Wheels and tyres
Inflating devices can display a pressure as
much as 0.1 bar too low.
Vehicle equipment
This chapter describes all standard, national
and special equipment provided in the model
series. Equipment not available in the vehicle is
therefore also described, for example the se‐
lected special equipment or national version.
This also applies to safety-relevant functions
and systems. Comply with the relevant na‐
tional regulations when using the correspond‐
ing functions and systems.
With runflat indicator: reinitialise the runflat in‐
dicator after adjusting tyre pressures.
With tyre pressure monitor: reset the tyre pres‐
sure monitor after adjusting the tyre pressure
to a new value.
Tyre inflation pressures
Tyre pressures
Information for your safety
A tyre’s condition and pressure influence the
following:
▷
▷
▷
Operating life of the tyre.
Driving safety.
The tyre inflation pressures specified for ap‐
proved tyre sizes are located on the door pillar
of the driver's door.
Driving comfort.
If the speed letter of the tyre cannot be found,
the tyre inflation pressure of the corresponding
size applies. The tyre inflation pressure data
apply to tyres at ambient temperature.
Checking tyre pressures
Checking tyre pressures regularly
Check tyre pressure regularly and adjust
as necessary, but at least twice a month and
before any long journey. Incorrect tyre pres‐
sures can adversely affect the car's road hold‐
ing and cause tyre damage, which could result
in an accident.◀
For Australia/New Zealand
Warning
The inflation pressures on the tyre label
are applicable only for tyres explicitly men‐
tioned on the label. Inflation pressures for tyres
that may be covered by the label – by size,
speed category and load rating/load index –
but not explicitly mentioned on the label may
be different. Please obtain adequate inflation
pressures in accordance with the tyre manu‐
facturer’s specifications at your tyre dealer.◀
Tyres have a natural, uniform tyre pressure
loss.
Tyres heat up when driving and with the tem‐
perature of the tyre, the tyre filling pressure in‐
creases. The tyre filling pressure data relate to
cold tyres or tyres at ambient temperature.
Only check the tyre pressure when the tyres
are cold. In other words, after driving for a max‐
imum of 2 km or if the vehicle has been parked
for at least 2 hours.

Tyre sizes
Inflation pressures refer to the approved and
recommended tyre sizes and tyre makes.
Tyre damage
General
Inspect tyres frequently for damage, the pres‐
ence of foreign bodies and wear.
Your Service centre will be glad to provide
more information on wheels and tyres.
Notes
Tyre tread
Vehicle behaviour that is an indication of tyre
damage or other faults:
Summer tyres
The tyre tread depth should not be less than
3 mm, 0.12 in.
▷
Unusual vibrations while the vehicle is in
motion.
▷
Unusual vehicle response, such as pro‐
nounced pulling to the left or right.
Below a tread depth of 3 mm, approximately
0.12 in, there is a high risk of aquaplaning.
Damage can be caused by, for example, run‐
ning over kerbs, road damage etc.
Winter tyres
The tyre tread depth should not be less than
4 mm, approximately 0.16 in.
In the event of tyre damage
If there are indications of tyre damage,
reduce speed immediately and have the
wheels and tyres checked without delay, oth‐
erwise there is an increased risk of accident.
Below a tread depth of 4 mm, approximately
0.16 in, suitability for vehicle operation in win‐
ter is restricted.
Drive carefully to the nearest Service Centre.
Allow vehicle to be towed or transported there,
otherwise tyre damage can cause danger of
death to vehicle occupants and also other
road-users.◀
Minimum tread depth
Repairing tyre damage
For safety reasons, the manufacturer of
your vehicle advises against having damaged
run-flat tyres repaired; have them replaced in‐
stead. Otherwise subsequent damage cannot
be excluded.◀
Wear indicators are distributed across the tyre
circumference and have the legally prescribed
minimum height of 1.6 mm, approximately
0.06 in.
Age of tyres
Recommendation
Irrespective of wear, change tyres after
six years at the latest.
They are identified on the tyre's side wall by
TWI, Tread Wear Indicator.
Date of manufacture
On the tyre side wall:

DOT … 0115: the tyre was made in the
1st week of 2015.
Recommended makes of tyre
Replacement of wheels and
tyres
Fitting
Information on tyre mounting
Only have tyres fitted, including balanc‐
ing, by your Service centre.
Certain makes of tyre are recommended by the
manufacturer of your vehicle depending on
tyre size. These can be seen by the asterisk on
the side wall of the tyre.
If such work is performed inexpertly, it could
result in consequential damage and thus con‐
stitute a safety risk.◀
When properly used, these tyres meet the
highest standards in terms of safety and han‐
dling characteristics.
Wheel and tyre combination
The correct wheel and tyre combination and
rim designs for the vehicle can be consulted at
the Service centre.
New tyres
New tyres do not achieve their full road
grip immediately, for production reasons.
Incorrect wheel and tyre combinations will in‐
terfere with the proper functioning of various
systems, such as ABS and DSC.
During the first 300 km, 200 miles, drive mod‐
erately.
To maintain good vehicle handling, always fit
tyres of the same make and tread pattern to all
wheels.
Retreaded tyres
The manufacturer of your vehicle advises
against the use of retreaded tyres.
After a tyre has been damaged, fit the original
wheel and tyre combination again.
Retreaded tyres
Approved wheels and tyres
Due to their potentially different internal
construction and advanced age, their durability
may be limited and their road safety therefore
questionable.◀
Only use wheels and tyres that are ap‐
proved by the manufacturer of the vehicle for
the corresponding vehicle type otherwise, for
example because of tolerances in spite of the
nominal size being the same, it is possible for
contact with the bodywork to occur, resulting
in serious accidents
Winter tyres
For operation on wintry carriageways, winter
tyres are recommended.
The manufacturer of your vehicle is unable to
assess the suitability of tyres and wheels it has
not approved, and therefore cannot guarantee
their safety.◀
Although so-called all-season tyres with an M
+S marking have better winter characteristics
than summer tyres, they do not normally
match the performance of winter tyres.

Top speed of winter tyres
Run-flat tyres
If the car is capable of speeds higher than the
speed permitted for the winter tyres, a sticker
stating the maximum permitted speed for the
tyres fitted must be displayed in the driver's
field of view. Specialist tyre dealers and your
Service centre can supply the sticker.
Label
Top speed for winter tyres
Do not exceed the top speed for the rele‐
vant winter tyres in use, otherwise tyre damage
potentially leading to an accident could oc‐
cur.◀
RSC marking on the tyre side wall.
Run-flat tyres
These wheels consist of tyres that are self-
supporting within certain limitations, and spe‐
cial rims.
For your own safety, when using run-flat tyres,
do not mix with other types of tyre. There is no
spare wheel available in the event of a punc‐
ture. Your Service Centre will be pleased to ad‐
vise.
The reinforced side wall means that the tyre
keeps the vehicle mobile to a degree even if
tyre pressure has been lost.
Observe the information on continuing to drive
with a flat tyre.
Interchanging front and rear wheels
Different tread wear patterns arise on the
wheels of the front and rear axles, depending
on the individual operating conditions. To ach‐
ieve even wear, it is possible to swap the
wheels over from one axle to the other. Your
Service Centre will be pleased to advise. After
changing, check the tyre pressure and adjust if
necessary.
Changing run-flat tyres
For your own safety, use only run-flat tyres.
There is no spare wheel available in the event
of a puncture. Your Service centre will be
pleased to advise.
Such a change is not permitted in vehicles with
different tyre or rim dimensions on the front
and rear axles.
Remedying punctures
Safety precautions in the event of a
puncture
Tyre storage
Store wheels and tyres in a cool, dry and pref‐
erably dark place when not in use.
Park the vehicle on a solid surface and as far
away from moving traffic as possible.
Switch on hazard warning lights.
Protect tyres against contamination from oil,
grease and fuel.
Engage the steering wheel lock in the straight
ahead position of the wheels.
Do not exceed the maximum tyre pressure in‐
dicated on the tyre's side wall.
Protect the vehicle against rolling, by applying
the parking brake.
Allow all occupants get out of the vehicle and
guide them out of the danger area, for example
behind the crash barrier.

Sealant container
Mobility system
Principle
With the mobility system, minor tyre damage
can be quickly sealed, to allow you to drive on.
To do that, liquid sealant is pumped into the
tyres which encloses the damage from the in‐
side when it hardens.

valve and connect it to the free connection
on the sealant container.
This can prevent sealant residues from es‐
caping from the container.
4. Pack empty sealant container to avoid soil‐
ing in the boot.
5. Store Mobility system in the vehicle again.
Spreading sealant compound
Immediately drive for approximately
10 km/5 mi to evenly distribute the sealing
compound in the tyre.
Switch off compressor after ten minutes
Do not operate the compressor for more
than ten minutes, otherwise the device will
overheat and this could result in damage.◀
Do not exceed a speed of 80 km/h/50 mph.
If possible, do not drive slower than
20 km/h/12 mph.
Let the compressor run for approximately
three to 8 minutes to fill the sealing compound
and achieve a tyre inflation pressure of approx‐
imately 2.5 bar.
Correcting the tyre inflation pressure
1. Stop in a suitable area.
2. Bolt the connecting hose of the compres‐
sor directly onto the tyre valve.
The tyre inflation pressure may rise to approxi‐
mately 5 bar during the filling process of the
sealing compound. Do not switch off the com‐
pressor during this step.
3. Insert the plug into the socket on the inside
of the vehicle.
4. Correct tyre inflation pressure to 2.5 bar.
If it does not reach a tyre inflation pressure of
2 bar:
▷
Increase pressure: switch on the com‐
pressor with the engine running or the
ignition switched on.
1. Switch off compressor.
2. Remove the filler hose from the wheel.
▷
Reduce pressure: press the button on
the compressor.
3. Drive forwards and backwards by 10 m, ap‐
proximately 400 inches to distribute the
sealant in the tyre.
Continuing with journey
Do not exceed maximum permitted speed of
80 km/h, approximately 50 mph.
4. Re-inflate the tyre with the compressor.
Contact a Service Centre if the device does
not reach a tyre inflation pressure of 2 bar.
Reinitialise runflat indicator.
Reinitialise Tyre Pressure Monitor.
