InformationWith use of the system observe further infor‐
mation found under Tire inflation pressure, re‐
fer to page 168.
Functional requirements
The system must have been reset with the
correct tire inflation pressure; otherwise, relia‐
ble signaling of tire inflation pressure loss is
not assured.
Reset the system after each adjustment of the
tire inflation pressure and after every tire or
wheel change.
Always use wheels with TPM electronics to
ensure that the system will operate properly.
Status display The current status of the Tire Pressure Moni‐
tor TPM can be displayed on the Control Dis‐
play, for example, whether or not the TPM is
active.1."Vehicle info"2."Vehicle status"3. "Tire Pressure Monitor (TPM)"
The status is displayed.
Status control display Tire and system status are indicated by the
color of the wheels and a text message on the
Control Display.
All wheels green System is active and will issue a warning rela‐
tive 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 due to a
malfunction.
Additional information The status control display additionally shows
the current tire inflation pressures and, de‐
pending on the model, tire temperatures. It
shows the actual values read; they may vary depending on driving style or weather condi‐
tions.
Carry out reset Reset the system after each adjustment of the
tire inflation pressure and after every tire or
wheel change.
On the Control Display and on the vehicle:1."Vehicle info"2."Vehicle status"3. "Perform reset"4.Start the engine - do not drive off.5.Reset tire inflation pressure: "Perform

The initialization automatically continues when
driving resumes.
Indication of a flat tire The yellow warning lamp lights up. A
Check Control message is displayed.
There is a flat tire or a major loss in tire
inflation pressure.1.Reduce your speed and stop cautiously.
Avoid sudden braking and steering maneu‐
vers.2.Identify the damaged wheel. Do so by
checking the tire inflation pressure using
the Mobility System. If the tire inflation
pressure in all tires is correct, the Flat Tire
Monitor may not have been initialized. In
this case, initialize the system.3.Repair flat tire with the Mobility System or
replace the damaged wheel.
System limits
A natural, even tire inflation pressure loss in all
four tires will not be recognized. Therefore,
check the tire inflation pressure regularly.
Sudden serious tire damage caused by exter‐
nal circumstances cannot be recognized in ad‐
vance.
The system could be delayed or malfunction in
the following situations:
▷When the system has not been initialized.▷When driving on a snowy or slippery road
surface.▷Sporty driving style: spinning traction
wheels, high lateral acceleration (drifting).▷When driving with snow chains.
Intelligent Safety
The concept
Intelligent Safety enables central operation of
the driver assistance system.
Depending on how the vehicle is equipped, In‐
telligent Safety consists of one or more sys‐
tems that can help prevent a imminent colli‐
sion. These systems are active automatically
every time the engine is started using the
Start/Stop button:▷Front-end collision warning with City Brak‐
ing function, refer to page 106.▷Pedestrian warning, refer to page 109.
Information
WARNING
Indicators and warnings do not relieve
the driver from personal responsibility. Due to
system limits, warnings or reactions of the sys‐
tem may not be output or they may be output
too late or incorrectly. There is risk of an acci‐
dent. Adjust the driving style to the traffic con‐
ditions. Watch traffic closely and actively inter‐
vene in the respective situations.◀
WARNING
Due to system limits, individual functions
can malfunction during tow-starting/towing
with the Intelligent Safety systems activated,
e.g., approach control warning with light brak‐
ing function. There is risk of an accident.
Switch all Intelligent Safety systems off prior to
tow-starting/towing.◀
