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.
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
TPMS low tire pressure telltale. The vehicle
has also been equipped with a TPMS malfunc-
tion indicator to indicate when the system is
not operating properly. The TPMS malfunction
indicator is combined with the low tire pres-
sure telltale. When the system detects a mal-
function, the telltale will flash for approximately
one minute and then remain continuously il-
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 diam-
eter and therefore the rate of rotation 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:
▷
After a tire or wheel change, an initialization
was carried out at the correct tire pressure.
▷
After the tire pressure was adjusted to a
new value, an initialization was performed.

Status display
Messages
The current status of the flat tire monitor can
be displayed, e.g., whether the flat tire monitor
is active.
General information
When a flat tire is indicated, the Dynamic Sta-
bility Control (DSC) is turned on, if needed.

Warning
A damaged regular tire with low or no tire
inflation pressure impacts handling such as
steering and braking response. There is a risk
of accident, injury, or property damage. Do
not continue driving. Repair the flat tire or re-
place the wheel.
Initialization required
An initialization must be performed in the fol-
lowing situations:
▷
After the tire inflation pressure has been
adjusted.
▷
After a tire or wheel change.
Indication of a flat tire
A yellow warning light is illuminated in
the instrument cluster.
Performing initialization
When initializing, the set tire inflation pressures
serve as reference values in order to detect a
flat tire. Initialization is started by confirming
the tire inflation pressures.
In addition, an icon with a Check Control mes-
sage appears on the control display.

Possible cause
Do not initialize the system when driving with
snow chains.
There is a flat tire or a major tire
pressure loss.

1. Reduce your speed and stop cautiously.
Avoid sudden braking and steering maneu-
vers.
5. Turn on drive-ready state and do not drive
off.
2. Read the description on what to do in case
of a flat tire.

7. Drive off.
The initialization is completed while driving,
which can be interrupted at any time.
Actions in the event of a flat tire
1. Identify the damaged tire.
The initialization automatically continues when
driving continues.
To do this, check the tire pressure in all four
tires, for instance using the tire pressure
display of a flat tire kit.
When the tire inflation pressure in all four
tires is correct, the flat tire monitor may not

over. There is a risk of injury or danger to life.
When the vehicle is raised with the jack, do
not lie under the vehicle and do not switch on
the drive-ready state.
If tire damage cannot be identified, contact
an authorized service center or another
qualified service center or repair shop.
2. Repair the flat tire, e.g., with a flat tire kit or
by changing the wheel.
Warning
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.
System limits
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
The jack, issued by the vehicle manufacturer,
is provided in order to perform a wheel
change in the event of a breakdown. The
jack is not designed for frequent use, e.g.,
changing from summer to winter tires. Using
the jack frequently may cause it to become
jammed or damaged. There is a risk of injury
and risk of damage to property. Only use the
jack to change an emergency or spare wheel
in the event of a breakdown.

When driving on a snowy or slippery road.
Sporty driving style: slip on traction wheels,

When driving with snow chains.
Changing wheels/tires
General information
When a flat tire kit is used, an immediate wheel
change when there is a tire pressure loss in the
event of a breakdown is not always necessary.
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
vehicle or cargo using the jack.
Warning
The jack is only provided for short-term lifting
of the vehicle for wheel changes. Even if all
safety precautions are observed, there is a
risk of the raised vehicle falling if the jack tips
