Operational readiness of airbag system

In the radio ready state and beyond, refer to

page 50, the warning lamp comes on briefly to

indicate that the entire airbag system and the

belt tensioners are operational.

Airbag system malfunction

▷ Warning lamp does not light up in the radio

ready state.

▷ Warning lamp remains permanently on.

Have the airbag system checked without

delay if there is a malfunction

In the event of a malfunction in the airbag sys‐

tem, have it checked without delay; otherwise,

there is the risk that the system will not function

as intended even if a sufficiently severe accident

occurs.◀

Flat Tire Monitor FTM*

The concept

The system detects a pressure loss in a tire on

the basis of speed differences between the in‐

dividual wheels during a trip.

In the event of pressure loss, the rolling circum‐

ference changes and, thus, the rotating speed

of the affected wheel. This change is detected

and is reported as a flat tire.

Functional requirements

The system must have been initialized when the

tire inflation pressure was correct; otherwise,

reliable signaling of a flat tire is not ensured. In‐

itialize the system after each correction of the

tire inflation pressure and after every tire or

wheel change.

System limits

Sudden tire damage

Sudden serious tire damage caused by

external influences cannot be indicated in ad‐

vance.◀

A natural, even pressure loss in all four tires can‐

not be detected.

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: slip in the drive wheels,

high lateral acceleration.

▷ When driving with snow chains.

Initialization

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*.

"Vehicle Info"

2. "Vehicle status"

3. "Reset"

4. Start the engine - do not drive away.

5. Start the initialization with "Reset".

6. Drive away.

The initialization is completed while driving,

which can be interrupted at any time.

The initialization automatically continues when

driving resumes.
