If the warning lamps for DSC come

on. DSC including DTC and DBC is

malfunctioning.

The stabilizing action and brake-

servo boost are no longer available. The vehicle

remains operational. Have the system checked

as soon as possible.

Drive-off assistant

The drive-off assistant enables you to drive off

smoothly on uphill gradients. It is not necessary

to use the handbrake for this.

1. Hold the car in place by pressing the brake

pedal.

2. Release the brake pedal and drive off with-

out delay.

The drive-off assistant holds the car in

place for approx. 2 seconds after the

brake pedal is released. Depending on vehicle

load, the car may roll backwards a little during

this time span. Drive off without delay after

releasing the brake pedal. Otherwise, the drive-

off assistant will no longer hold the car in place

after approx. 2 seconds and the car will start to

roll backwards.<

Malfunction

The warning lamps for the brake sys-

tem light up in yellow. The drive-off

assistant has failed. The car will not

be held in place after the brake pedal

is released. Have the system checked as soon

as possible.

Display of this malfunction on Cana-

dian models.

Flat Tire Monitor FTM

The concept

The Flat Tire Monitor monitors tire pressures

while the car is being driven. The system

reports any significant loss of pressure in one

tire in relation to another.

If a tire loses pressure, its rolling radius

changes, and this in turn alters the speed of

rotation. This change is detected and is

reported as a flat tire.

Functional requirement

In order to assure the reliable reporting of a flat

tire, the system must be initialized for the cor-

rect tire inflation pressure.

The system must be reinitialized each

time a tire inflation pressure has been cor-

rected or a wheel or tire has been changed.<

System limitations

The Flat Tire Monitor is unable to warn

the driver of sudden, severe tire damage

caused by external factors, nor can it identify

the gradual loss of pressure that will inevitably

occur in all four tires over a lengthy period of

time.<

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

> If snow chains are attached

Initializing the system

The initialization is completed during driv-

ing, which can be interrupted at any time.

When driving resumes, the initialization is con-

tinued automatically.

Do not initialize the system while snow chains

are attached.<
