Initialization
When initializing the once set inflation tire pres‐
sures serve as reference values in order to de‐
tect a flat tire. Initialization is started by con‐
firming the inflation pressures.
Do not initialize the system when driving with
snow chains.
1.
Press button.
2. "Vehicle Info"
3. "Vehicle status"
4. "Flat Tire Monitor (FTM)"
5. Start the engine - do not drive off.
6. Start the initialization with "Flat Tire
Monitor (FTM) reset".
7. Drive away.
The initialization is completed while driving,
which can be interrupted at any time.
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. Check whether the vehicle is fitted with
regular tires or run-flat tires.
Run-flat tires, refer to page 184, are la‐
beled with a circular symbol containing the
letters RSC marked on the tire's sidewall.
Do not continue driving without run-flat
tires
Do not continue driving if the vehicle is not
equipped with run-flat tires; continued driving
may result in serious accidents.◀
When a flat tire is indicated, DSC Dynamic Sta‐
bility Control is switched on if needed.
System limits
Sudden tire damage
Sudden serious tire damage caused by
external circumstances cannot be recognized in
advance.◀
A natural, even tire inflation pressure loss in all
four tires will not be recognized. Therefore,
check the tire inflation pressure regularly.
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.
Actions in the event of a flat tire
Normal tires
1.
Identify the damaged tire.
Do this by checking the air pressure in all
four tires.
The tire pressure gauge of the Mobility Sys‐
tem, refer to page 185, can be used for this
purpose.
If the tire inflation pressure in all four tires is
correct, the Flat Tire Monitor may not have
been initialized. In this case, initialize the
system.
If an identification is not possible, please
contact the service center.
2.
Fix the flat tire using the Mobility System,
refer to page 185.
