System limitations
Sudden serious tire damage caused by
external influences cannot be indicated in
advance.<
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
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.
Using the button in the turn signal lever
1. Start the engine, but do not start driving.
2. Press the button on the turn signal indicator
as often as necessary until "SET/INFO" is dis-
played.
3. Press and hold the button until the display
changes.
4. Briefly press the button repeatedly until the
corresponding symbol and "RESET" are dis-
played.
5. Press and hold the button until the display
changes.
6. Start driving.
Initialization is completed while the car is on
the move, without any feedback.
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. 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 136, are identi-
fied by a circular symbol containing the let-
ters RSC on the tire sidewall.
If the vehicle is not equipped with run-flat
tires, do not continue driving; continuing
to drive can result in serious accidents.<
When a flat tire is reported, the Dynamic Stability
Control DSC is activated.
