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.
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.
Drive-off assistant
The system must be reinitialized each
time a tire inflation pressure has been cor-
rected or a wheel or tire has been changed.<
The drive-off assistant enables you to drive off
smoothly on uphill gradients. It is not necessary
to use the handbrake for this.
System limitations
1.
Hold the car in place by pressing the brake
pedal.
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.<
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
In the following situations, the system could be
delayed or malfunction:
releasing the brake pedal. Otherwise, the drive- >
System has not been initialized
off assistant will no longer hold the car in place
after approx. 2 seconds and the car will start to
roll backwards.<
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
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.
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.<

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.
