sure specifications apply to the tire sizes ap-  
proved by the vehicle manufacturer for the cor-  
responding vehicle types.  
Vehicle features and options  
This chapter describes model-specific equip-  
ment, systems, and functions that are currently  
available, or may become available in the fu-  
ture, even if they are not present in the vehicle.  
To identify the correct tire inflation pressure,  
please note the following:  
Tire sizes of the vehicle.  
Additional information:  
Maximum speed for driving.  
Vehicle equipment, refer to page 8.  
On the control display  
The current tire inflation pressure values and  
the intended tire inflation pressure values for  
the mounted tires can be displayed on the con-  
trol display.  
Tire pressure  
General information  
The tire condition and tire pressure influence  
the following:  
To ensure that they are displayed correctly, the  
tire sizes must be stored in the system and  
must have been set for the mounted tires.  
The service life of the tires.

Safety information  
Checking the tire pressure  
General information  
Warning  
The tires heat up while driving. The tire pres-  
sure increases with the tire temperature.  
A tire with too little or no tire inflation pres-  
sure may heat up significantly and sustain  
damage. This will have a negative impact  
on aspects of handling such as steering and  
braking response. There is a risk of accident.  
Regularly check the tire inflation pressure,  
and correct it as needed, for instance twice  
a month and before a long trip.  
Tires have a natural, consistent tire pressure  
loss.  
The displays of inflation devices may under-  
read by up to 0.1 bar/2 psi.  
Checking via tire inflation pressure  
specifications in tire pressure table  
1. Determine the intended tire inflation pres-  
sure levels for the mounted tires.

2. Check the tire inflation pressure in all four  
tires, using a pressure gage, for example.

tion pressure specifications for given tire sizes  
at ambient temperature. The tire inflation pres-

pressure values on the control display, reset  
the Tire Pressure Monitor (TPM).  
If equipped with a flat tire monitor, reinitialize  
the flat tire monitor.  
4. Make sure that all valve caps are screwed  
onto the tire valves.  
Tire inflation pressures up to  
100 mph/160 km/h  
For speeds of up to 100 mph/160 km/h and for  
optimum driving comfort, follow the tire infla-  
tion pressure specifications in the tire pressure  
table and adjust as necessary.  
The tire inflation pressure specifications in the  
tire inflation pressure table only relate to cold  
tires or tires at the same temperature as the  
ambient temperature.  
Only check the tire inflation pressure levels  
when the tires are cold, i.e.:  
A distance traveled of max. 1.25 miles/2 km  
has not been exceeded.  
If the vehicle has not moved again for at  
least two hours after a trip.  
If equipped with an emergency wheel: check  
the tire pressure of the emergency wheel in the  
cargo area regularly and correct if necessary.  
Checking using the tire inflation  
pressure specifications on the control  
display  
The tire inflation pressure specifications can  
also be found on the tire pressure label on the  
driver's door pillar.

The treadwear grade is a comparative rating  
based on the wear rate of the tire when tested  
under controlled conditions on a specified gov-  
ernment test course. E.g., a tire graded 150  
would wear one and one-half, 1 g, times as  
well on the government course as a tire graded  
100. The relative performance of tires depends  
upon the actual conditions of their use, how-  
ever, and may depart significantly from the  
norm due to variations in driving habits, service  
practices and differences in road characteris-  
tics and climate.

Traction  
M+S  
The traction grades, from highest to lowest,  
are AA, A, B, and C.  
Winter tires, as well as all-season tires with  
better winter performance than summer tires,  
can be identified by the M+S marking on the  
tire side wall.  
Those grades represent the tire's ability to  
stop on wet pavement as measured under  
controlled conditions on specified government  
test surfaces of asphalt and concrete. A tire  
marked C may have poor traction perform-  
ance.  
Tire tread  
Safety information  
Warning  
The traction grade assigned to this tire is  
based on straight-ahead braking traction tests,  
and does not include acceleration, cornering,  
hydroplaning, or peak traction characteristics.  
If the tire tread depth is too low, driving safety  
may be impaired in critical situations such as  
aquaplaning or slush on the road. There is  
a risk of accident. The tire tread depth may  
not fall below 0.12 in/3 mm for summer tires  
and 0.16 in/4 mm for winter and all-season  
tires, or observe the statutory regulations on  
minimum tread depth.  
Temperature  
The temperature grades are A, the highest, B,  
and C, representing the tire's resistance to the  
generation of heat and its ability to dissipate  
heat when tested under controlled conditions  
on a specified indoor laboratory test wheel.  
Sustained high temperature can cause the  
material of the tire to degenerate and reduce  
tire life, and excessive temperature can lead to  
sudden tire failure. The grade C corresponds  
to a level of performance which all passenger  
car tires must meet under the Federal Motor  
Vehicle Safety Standard No. 109. Grades Band  
A represent higher levels of performance on  
the laboratory test wheel than the minimum  
required by law.  
Minimum tread depth  
Warning  
The temperature grade for this tire is estab-  
lished for a tire that is properly inflated and  
not overloaded. Excessive speed, underinfla-  
tion, or excessive loading, either separately  
or in combination, can cause heat buildup  
and possible tire failure.  
The tire manufacturer’s wear indicators are  
distributed over the tire circumference. These  
indicators have a height of min. 0.06 in/1.6 mm  
and serve as an indicator for tire tread wear.  
The positions of the wear indicators are  
marked on the tire sidewall with TWI, Tread  
Wear Indicator.  
Runflat tires  
Runflat tires, refer to page 272, are labeled  
with a circular icon containing the letters RSC  
marked on the tire sidewall.

Wheels and tires  
MOBILITY  
Tire damage  
Warning  
Driving over curbs, road damage or other ob-  
stacles can damage wheels, tires and chassis  
components. Larger wheels have a smaller  
tire cross-section. The smaller the tire cross-  
section, the higher the risk of tire damage.  
There may be a risk of accidents and risk of  
damage to property. If possible, avoid driving  
over curbs, road damage or other obstacles,  
or drive over them slowly and carefully.  
General information  
Check your tires regularly for damage, foreign  
bodies lodged in the tread, and tread wear.  
Indications of tire damage or another vehicle  
malfunction:  
Unusual vibrations.  
Unusual tire or running noises.  
Unusual handling such as a strong ten-  
dency to pull to the left or right.  
Uneven wear pattern, e.g., increased wear  
in the area of the tire shoulder.  
Exchanging wheels and  
tires  
Damage can be caused by the following situa-  
tions, for instance:  
Driving over curbs.  
Road damage.  
Mounting and wheel balancing  
Have the wheel mounted and balanced by an  
authorized service center or another qualified  
service center or repair shop.  
Tire pressure too low.  
Vehicle overloading.  
Incorrect tire storage.  
Suitable wheels and tires  
Safety information  
General information  
Only certain wheel/tire combinations are suit-  
able depending on vehicle and equipment.  
The vehicle manufacturer determines wheel/  
tire combinations on the basis of the following  
criteria:  
Warning  
Damaged tires can lose tire inflation pres-  
sure, which can lead to loss of vehicle con-  
trol. There is a risk of accident. If tire dam-  
age is suspected while driving, immediately  
reduce speed and stop. Have wheels and  
tires checked. To do so, drive carefully to  
an authorized service center or another quali-  
fied service center or repair shop. Have the  
vehicle towed or transported as needed. Do  
not repair damaged tires, but have them re-  
placed.  
Tire size, e.g., tire width, aspect ratio.  
Wheel size, e.g., rim diameter, offset.  
Ask an authorized service center or another  
qualified service center or repair shop about  
wheels and tires that are suitable for the vehi-  
cle as well as special equipment.

MOBILITY  
Safety information  
Recommended tire brands  
Warning  
Wheels and tires that are not suitable for  
the vehicle can damage parts of the vehi-  
cle. There is a risk of accident. The vehi-  
cle manufacturer recommends that you use  
only wheels and tires that have been recom-  
mended for the vehicle type.  
Tire types are developed for each vehicle and  
optimized specifically for the individual require-  
ments of that vehicle, e.g.:  
Warning  
Mounted steel wheels can cause technical  
problems, for instance unexpected loosening  
of the lug bolts and damage to the brake  
disks. There is a risk of accident. Do not  
mount steel wheels.  
Handling.  
Comfort.  
Noise characteristics.  
Specially developed tires are marked with  
a star on the tire sidewall. After replacing  
wheels and tires, the vehicle manufacturer rec-  
ommends using star-marked tires again. The  
vehicle manufacturer recommends that you  
use tires of the same make and tread design.  
Warning  
Wheel/tire combinations that are not suitable  
to the vehicle can impair vehicle handling and  
a number of system functions such as the  
Antilock Braking System or Dynamic Stability  
Control. There is a risk of accident. The man-  
ufacturer of the vehicle recommends that you  
use wheels and tires that have been recom-  
mended by the vehicle manufacturer for the  
vehicle type. Following tire damage, have the  
original wheel/tire combination remounted on  
the vehicle as soon as possible.  
New tires  
Tire traction is not optimal due to manufactur-  
ing circumstances when tires are brand new.  
Drive conservatively for the first  
200 miles/300 km.  
Retreaded tires  
Warning  
Retreated tires can have different tire casing  
structures. With advanced age the service life  
can be limited. There is a risk of accident.  
The manufacturer of the vehicle does not rec-  
ommend the use of retreaded tires.

Changing runflat tires  
When changing from runflat tires to standard  
tires, it must be ensured that the vehicle con-  
tains an emergency wheel or tire mobility kit.  
For more information, contact an authorized  
service center or another qualified service cen-  
ter or repair shop.  
Safety information  
Warning  
If the maximum permissible speed of your  
mounted tires is exceeded, the tires may be  
damaged. There is a risk of accident. Do not  
exceed the maximum permissible speed of  
the tires.  
Wheel change between axles  
Warning  
A wheel change between the axles on vehi-  
cles with different tire sizes or rim sizes on  
the front and rear axles can cause damage  
to the tires and the vehicle. There is a risk of  
accident. Do not rotate the tires between the  
axles on vehicles with different tire sizes or  
rim sizes on the front and rear axles.  
Maximum speed of winter tires  
If the maximum speed of the vehicle is higher  
than the maximum permissible speed of the  
winter tires, the maximum permissible speed  
must be indicated with a sign placed in the  
field of vision. The info label is available from  
an authorized service center or another quali-  
fied service center or repair shop.  
Different abrasion patterns can occur on the  
front and rear axles depending on individual  
driving conditions. The tires can be rotated in  
pairs between the axles to achieve even abra-  
sion. For more information, contact an author-  
ized service center or another qualified service  
center or repair shop. After changing, check  
the tire pressure and correct, if needed.  
Winter tires  
Storing tires  
Tire pressure  
Do not exceed the maximum tire inflation pres-  
sure indicated on the tire sidewall.  
Winter tires are recommended for operating on  
winter roads.  
Winter tires can be identified by the moun-  
tain/snowflake icon and the letters M+S on the  
tire sidewall.  
Storage  
Store wheels and tires in a cool, dry and  
dark place.  
So-called all-season tires with M+S marking  
but without mountain and snowflake icon have  
better winter properties than summer tires.  
As a rule, all-season tires do not perform the  
same as winter tires.  
Always protect tires against all contact with  
oil, grease, and solvents.  
Do not leave the tires in plastic bags.  
Remove dirt from wheels or tires.

General information  
The wheels consist of tires that are self-sup-  
porting to a limited degree and may also in-  
clude special rims.  
Turn the steering wheel until the front  
wheels are in the straight-ahead position  
and engage the steering wheel lock.  
As soon as permitted by the traffic flow,  
have all vehicle occupants get out and  
make sure that they remain outside the  
hazardous area such as behind a guardrail.  
The reinforcement of the sidewall allows the  
tire to remain drivable to a limited degree in  
the event of a tire pressure loss.  
Follow the instructions for continued driving  
with a flat tire.  
If necessary, set up the hazard triangle or  
hazard warning lights at an appropriate  
distance.  
Safety information  
Tire repair set  
Warning  
The vehicle handles differently when a runflat  
tire has insufficient or no tire pressure; for  
instance, reduced directional stability when  
braking, braking distances are longer and the  
self-steering properties will change. There is  
a risk of accident. Drive moderately and do  
not exceed a speed of 50 mph/80 km/h.  
Principle  
With the tire repair set, minor tire damage  
can be sealed temporarily to enable continued  
driving.  
General information  
The filled in tire sealant closes the damage  
from the inside when it hardens.  
Identification  
Follow the instructions on using the tire re-  
pair set found on the compressor and seal-  
ant bottle.  
The use of a tire repair set can be ineffec-  
tive if the tire puncture measures above ap-  
prox. 0.16 in/4 mm.  
Do not remove foreign objects that have  
penetrated the tire. Remove foreign objects  
only when they are visibly protruding from  
the tire.  
Runflat tires are labeled with a circular icon  
containing the letters RSC marked on the tire  
sidewall.  
The compressor can be used to check the  
tire inflation pressure.

Continued driving with a flat tire  
System limits  
Follow the following when continuing to drive  
with a damaged tire:  
Temperature  
The tire inflation pressure depends on the  
tire's temperature.  
1. Avoid sudden braking and steering maneu-  
vers.  
Driving or exposure to the sun will increase the  
tire temperature, thus increasing the tire infla-  
tion pressure.  
2. Do not exceed a speed of  
50 mph/80 km/h.  
3. Check the tire inflation pressure in all four  
tires at the next opportunity.  
The tire inflation pressure is reduced when the  
tire temperature falls again.  
Possible driving distance with a flat tire  
These circumstances may cause a warning  
when temperatures fall very sharply.  
The possible driving distance which may be  
safely traveled varies depending on how the  
vehicle is loaded and used, e.g., speed, road  
conditions, outside temperature. The distance  
traveled may be less but may also be more if  
an economical driving style is used.  
Following a temperature-related warning, the  
target pressures are displayed on the control  
display again after a short distance.  
Sudden tire pressure loss  
If the vehicle is loaded with an average  
weight and used under favorable conditions,  
the possible distance traveled may be up to  
50 miles/80 km.  
The system cannot indicate sudden and se-  
rious tire damage caused by external circum-  
stances.  
Failure performing a reset  
Vehicle handling with damaged tires  
Tires with special approval: the system will not  
function correctly if a reset was not performed,  
for example a flat tire may be indicated al-  
though the tire inflation pressures are correct.  
Vehicles driven with a damaged tire will han-  
dle differently, potentially leading to conditions  
such as the following:  
Greater likelihood of skidding of the vehicle.  
Longer braking distances.  
Malfunction  
Changed self-steering properties.  
Message  
Modify your driving style. Avoid abrupt steering  
or driving over obstacles, for instance curbs or  
potholes.  
The yellow warning light flashes and is  
then illuminated continuously. A Check  
Control message is displayed. It may  
not be possible to identify tire pressure losses.  
Final tire failure  
Vibrations or loud noises while driving can indi-  
cate the final failure of a tire.  
Measure  
Reduce speed and stop; otherwise, pieces of  
the tire could come loose and cause an acci-  
dent.

one minute and then remain continuously il-  
luminated. This sequence will continue upon  
subsequent vehicle start-ups as long as the  
malfunction exists. When the malfunction indi-  
cator is illuminated, the system may not be  
able to detect or signal low tire pressure as  
intended. TPMS malfunctions may occur for a  
variety of reasons, including the installation of  
replacement or alternate tires or wheels on the  
vehicle that prevent the TPMS from function-  
ing properly. Always check the TPMS malfunc-  
tion telltale after replacing one or more tires  
or wheels on the vehicle to ensure that the re-  
placement or alternate tires and wheels allow  
the TPMS to continue to function properly.  
For tires with special approval: the system  
was unable to complete the reset. Perform  
a system reset again.  
If the Tire Pressure Monitor malfunctions:  
Have the vehicle checked by an authorized  
service center or another qualified service  
center or repair shop.  
Declaration according to NHTSA/  
FMVSS 138 Tire Pressure Monitoring  
System  
Each tire, including the spare (if provided)  
should be checked monthly when cold and in-  
flated to the inflation pressure recommended  
by the vehicle manufacturer on the vehicle  
placard or tire inflation pressure label. (If the  
vehicle has tires of a different size than the  
size indicated on the vehicle placard or tire  
inflation pressure label, you should determine  
the proper tire inflation pressure for those  
tires.) As an added safety feature, the vehi-  
cle has been equipped with a tire pressure  
monitoring system (TPMS) that illuminates a  
low tire pressure telltale when one or more  
of your tires is significantly under-inflated. Ac-  
cordingly, when the low tire pressure telltale  
illuminates, you should stop and check your  
tires as soon as possible, and inflate them to  
the proper pressure. Driving on a significantly  
under-inflated tire causes the tire to overheat  
and can lead to tire failure. Under-inflation also  
reduces fuel efficiency and tire tread life, and  
may affect the vehicle's handling and stopping  
ability. Please note that the TPMS is not a  
substitute for proper tire maintenance, and it  
is the driver's responsibility to maintain correct  
tire pressure, even if under-inflation has not  
reached the level to trigger illumination of the

Flat tire monitor  
Principle  
The flat tire monitor detects a tire pressure  
loss while driving and issues a warning if the  
tire pressure has dropped.  
General information  
The system detects tire pressure loss on the  
basis of rotation speed differences between  
the individual wheels while driving.  
In the event of a tire pressure loss, the diame-  
ter and therefore the rotational speed of the  
corresponding wheel changes. The difference  
will be detected and reported as a flat tire.  
The system does not measure the actual infla-  
tion pressure in the tires.  
Functional requirements  
The following prerequisites must be met for  
the system; otherwise, reliable notification of a  
tire pressure loss is not assured:

Possible driving distance with a flat tire  
If tire damage cannot be identified, contact  
an authorized service center or another  
qualified service center or repair shop.  
The possible driving distance which may be  
safely traveled varies depending on how the  
vehicle is loaded and used, e.g., speed, road  
conditions, outside temperature. The distance  
traveled may be less but may also be more if  
an economical driving style is used.  
2. Repair the flat tire, for instance with a tire  
repair set or by changing the wheel.  
Runflat tires  
If the vehicle is loaded with an average  
weight and used under favorable conditions,  
the possible distance traveled may be up to  
50 miles/80 km.  
Safety information  
Warning  
Vehicle handling with damaged tires  
The vehicle handles differently when a runflat  
tire has insufficient or no tire pressure; for  
instance, reduced directional stability when  
braking, braking distances are longer and the  
self-steering properties will change. There is  
a risk of accident. Drive moderately and do  
not exceed a speed of 50 mph/80 km/h.  
Vehicles driven with a damaged tire will han-  
dle differently, potentially leading to conditions  
such as the following:  
Greater likelihood of skidding of the vehicle.  
Longer braking distances.  
Changed self-steering properties.  
Modify your driving style. Avoid abrupt steering  
or driving over obstacles, for instance curbs or  
potholes.  
Maximum speed  
You may continue driving with a damaged tire  
at speeds up to 50 mph/80 km/h.

When the vehicle is raised with the jack, do  
not lie under the vehicle and do not switch on  
the drive-ready state.  
Do not continue driving. Contact an authorized  
service center or another qualified service cen-  
ter or repair shop.  
Warning  
System limits  
Placing supports, e.g., wooden blocks or sim-  
ilar, under the jack may reduce its ability to  
bear weight because of the limited height.  
The load-carrying capacity of the wooden  
blocks may be exceeded and the vehicle may  
tip over. There is a risk of injury or danger to  
life. Do not place supports under the jack.  
The system may be delayed or malfunction in  
the following situations:  
A natural, even tire pressure loss in all  
four tires will not be recognized. Therefore,  
check the tire inflation pressure regularly.  
Sudden and serious tire damage caused  
by external circumstances cannot be recog-  
nized in advance.  
Warning

Changing wheels/tires  
General information  
When using runflat tires or a tire repair set, the  
wheel does not always need to be changed  
immediately in the event of a breakdown when  
there is tire pressure loss.  
Warning  
The jack may slip on soft, uneven, or slippery  
ground, e.g., snow, ice, tiles, etc. There is a  
risk of injury. If possible, change the wheel on  
a flat, solid, slip-resistant surface.  
If necessary, a suitable wheel change tool, e.g.,  
a jack, is available as an accessory from an  
authorized service center or another qualified  
service center or repair shop.  
Warning  
Safety information  
The jack is optimized for lifting the vehicle  
and for the jacking points on the vehicle only.  
There is a risk of injury. Do not lift any other
