MOBILITY
Vehicle handling with damaged tires
Vehicles driven with a damaged tire will handle
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
maneuvers or driving over obstacles, for instance
curbs or potholes.
Final tire failure
Vibrations or loud noises while driving can indi‐
cate the final failure of a tire.
Reduce speed and stop; otherwise, pieces of the
tire could come loose and cause an accident.
Do not continue driving. Contact a dealer's serv‐
ice center or another qualified service center or
repair shop.
System limits
Temperature
The tire inflation pressure depends on the tire's
temperature.
Driving or exposure to the sun will increase the
tire's temperature, thus increasing the tire infla‐
tion pressure.
The tire inflation pressure is reduced when the
tire temperature falls again.
These circumstances may cause a warning
when temperatures fall very sharply.
Following a temperature-related warning, the tar‐
get pressures are displayed on the Control Dis‐
play again after a short distance.
Sudden tire pressure loss
The system cannot indicate sudden serious tire
damage caused by external circumstances.

Failure performing a reset
Tires with special approval: the system will not
function correctly if a reset was not performed,
for example a flat tire may be indicated although
the tire inflation pressures are correct.
Malfunction
Message
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.
Measure
▷ A wheel without wheel electronics, such as
an emergency wheel, is mounted: have the
wheels checked, if needed.
▷ Fault caused by systems or devices with the
same radio frequency: after leaving the area
of the interference, the system automatically
becomes active again.
▷ For tires with special approval: the system
was unable to complete the reset. Perform a
system reset again.
▷ Tire Pressure Monitor malfunction: have the
system checked by a manufacturer 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 inflated to
the inflation pressure recommended by the vehi‐
cle manufacturer on the vehicle placard or tire in‐
flation pressure label. (If your vehicle has tires of
a different size than the size indicated on the ve‐
hicle placard or tire inflation pressure label, you
should determine the proper tire inflation pres‐
sure for those tires.) As an added safety feature,
your vehicle has been equipped with a tire pres‐
