Shift indication appears only in
manual mode.
Electronic driving
programmes
● Following a cold start, the
operating temperature
programme increases engine
speed to quickly bring the
catalytic converter to the required
temperature.
● The adaptive programme tailors
gearshifting to the driving
conditions, e.g. greater load or
gradients.
Kickdown
If the accelerator pedal is pressed
down completely in automatic mode,
the transmission shifts to a lower gear
depending on engine speed.

Fault

To prevent damage to the manual
transmission automated, the clutch is
engaged automatically at high clutch
temperatures.
In the event of a fault, a warning
message is displayed in the Driver
Information Centre. Vehicle
messages 3 123.
Continued driving is restricted or not
possible, depending on the fault.
Have the cause of the fault remedied
by a workshop.

Brakes

The brake system comprises two
independent brake circuits.
If a brake circuit fails, the vehicle can
still be braked using the other brake
circuit. However, braking effect is
achieved only when the brake pedal
is depressed firmly. Considerably
more force is needed for this. The
braking distance is extended. Seek
the assistance of a workshop before
continuing the journey.
When the engine is not running, the
support of the brake servo unit
disappears once the brake pedal has
been depressed once or twice.
Braking effect is not reduced, but
braking requires significantly greater
force. It is especially important to bear
this in mind when being towed.
Control indicator R 3 111.

Antilock brake system

Antilock brake system (ABS)
prevents the wheels from locking.
