Technology for driving comfort and safety
70
A natural, even pressure loss in all four tires can-
not be detected. Therefore, check the tire infla-
tion pressure regularly.
In the following situations, the system could be
delayed or malfunction:
> System has not been initialized
> Driving on snowy or slippery road surface
> Performance-oriented style of driving: slip in
the drive wheels, high lateral acceleration
> Snow chains are attached
Status display
The current status of the Flat Tire Monitor can be
displayed on the Control Display, e.g. whether or
not the FTM is active.
1. "Vehicle Info"
2. "Vehicle status"
3. "Flat Tire Monitor"
The status is displayed.
Initializing the system
The initialization process adopts the set inflation
tire pressures as reference values for the detec-
tion of a flat tire. Initialization is started by con-
firming the inflation pressures.
Do not initialize the system when driving with
snow chains.
1. "Vehicle Info"
2. "Vehicle status"
3. "Reset"
4. Start the engine, but do not start driving.
5. Select "Reset" to start the initialization.
6. Start to drive.
The initialization is completed during driv-
ing, which can be interrupted at any time.
When driving resumes, the initialization is con-
tinued automatically.<
Indication of a flat tire
The warning lamps come on in yellow
and red. A message appears on the
Control Display. An acoustic signal also
sounds.
There is a flat tire or a major loss in tire inflation
pressure.
1. Reduce speed and stop the vehicle with cau-
tion. Avoid sudden braking and steering
maneuvers.
2. Check whether the vehicle is equipped with
normal tires or with run-flat tires
*.
Run-flat tires, refer to page 181, are identi-
fied by a circular symbol containing the let-
ters RSC on the tire sidewall.
When a flat tire is reported, the Dynamic Stability
Control DSC is activated.
Actions in the event of a flat tire
Normal tires*
1. Identify the damaged tire.
To do so, check the inflation pressure in all
four tires.
The inflation pressure display of the Mobility
System, page 197, can be used for this pur-
pose.
