speed, road conditions, external temperature.
The driving range may be less but may also be
more if an economical driving style is used.
If the vehicle is loaded with an average weight
and used under favorable conditions, its possi‐
ble driving range will be up to 50 miles/80 km.
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 swerving off course.
▷ Longer braking distances.
▷ Changed self-steering properties.
Adjust driving style. Avoid abrupt steering ma‐
neuvers or driving over obstacles, for instance
curbs, potholes, etc.
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 acci‐
dent.
Do not continue driving. Contact a dealer's
service center or another qualified service cen‐
ter or repair shop.
System limits
The system does not function properly if a re‐
set has not been carried out, for instance a flat
tire is reported though tire inflation pressures
are correct.
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 inflation pressure. The tire
inflation pressure is reduced when the tire
temperature falls again. These circumstances
may cause a warning when temperatures fall
very sharply.
The system cannot indicate sudden serious
tire damage caused by external circumstances.

Safety
Malfunction
The yellow warning light flashes and is
then illuminated continuously. A Check
Control message is displayed. No flat
tire or loss of tire inflation pressure can be de‐
tected.
Examples and recommendations in the follow‐
ing situations:
▷ A wheel without TPM electronics is
mounted: have it checked by a dealer's
service center or another qualified service
center or repair shop as needed.
▷ Malfunction: have system checked by a
dealer's service center or another qualified
service center or repair shop.
▷ TPM was unable to complete the reset.
Reset the system again.
▷ Interference caused by systems or devices
with the same radio frequency: after leav‐
ing the area of the interference, the system
automatically becomes active again.
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 your
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, your vehicle has
been equipped with a tire pressure monitoring
system (TPMS) that illuminates a low tire pres‐
sure telltale when one or more of your tires is
significantly under-inflated. Accordingly, when
the low tire pressure telltale illuminates, you
should stop and check your tires as soon as
possible, and inflate them to the proper pres‐
sure. Driving on a significantly under-inflated
tire causes the tire to overheat and can lead to
