braking distance, and altered self-steering
properties. Adjust your driving style accord‐
ingly. Avoid abrupt steering maneuvers or driv‐
ing over obstacles, e.g., curbs, potholes, etc.
Because the possible driving distance depends
on how the vehicle is used during the trip, the
actual distance may be smaller or greater de‐
pending on the driving speed, road conditions,
external temperature, cargo load, etc.
Continued driving with a flat tire
Drive moderately and do not exceed a
speed of 50 mph/80 km/h.
A loss of tire inflation pressure results in a
change in the handling characteristics, e.g., re‐
duced lane stability during braking, a longer
braking distance and altered self-steering prop‐
erties.◀
Final tire failure
Vibrations or loud noises while driving can
indicate the final failure of the tire. Reduce speed
and stop; otherwise, pieces of the tire could
come loose and cause an accident. Do not con‐
tinue driving, and contact your service center.◀
Tire Pressure Monitor TPM
The concept
The system monitors tire pressure in the four
mounted tires. The system warns you if there is
a significant loss of pressure in one or more tires.
For this purpose, sensors in the tire valves
measure the tire pressure and tire temperature.
Hints
Tire damage due to external factors
Sudden tire damage caused by external
influences cannot be indicated in advance.◀
Pay attention to the other information and indi‐
cations under Tire inflation pressure, refer to
page
191 , as well when using the system.
Functional requirements
The system must have been reset with the cor‐
rect tire inflation pressure; otherwise, reliable
signaling of tire pressure loss is not ensured.
Reset the system again after each correction of
the tire inflation pressure and after every tire or
wheel change.
Always use wheels with TPM electronics to en‐
sure that the system will operate properly.
Status display
The current status of the Tire Pressure Monitor
TPM can be displayed on the Control Display,
e.g., whether or not the TPM is active.
1. "Vehicle Info"
2. "Vehicle status"
3. "Tire Pressure Monitor - TPM"
The status is displayed.
Status display
The tire and system status is indicated by the
color of the tires and a text message on the Con‐
trol Display.
All wheels green
System is active and will issue a warning relative
to the tire inflation pressures stored during the
last reset.
One wheel is yellow
A flat tire or major drop in inflation pressure in
the indicated tire.
All wheels are yellow
A flat tire or major drop in inflation pressure in
several tires.
Wheels, gray
The system cannot detect a flat tire. Reasons for
this may be:
▷ The system is being reset.
▷ Malfunction.
