Overrun cut-off The fuel supply is automatically cut off
during overrun, i.e. when the vehicle
is driven with a gear engaged but
accelerator is released.
Stop-start system The stop-start system helps to save
fuel and to reduce the exhaust
emissions. When conditions allow, it
switches off the engine as soon as the
vehicle is at a low speed or at a
standstill, e.g. at a traffic light or in a
traffic jam. It restarts the engine
automatically as soon as the clutch
pedal is depressed.
A vehicle battery sensor ensures that
an Autostop is only performed if the
vehicle battery is sufficiently charged
for a restart.
Driving and operating129Control indicator R 3 86.
Vehicle messages 3 91.
Antilock brake system Antilock brake system (ABS)
prevents the wheels from locking.
ABS starts to regulate brake pressure
as soon as a wheel shows a tendency to lock. The vehicle remains
steerable, even during hard braking.
ABS control is made apparent
through a pulse in the brake pedal
and the noise of the regulation
process.
For optimum braking, keep the brake
pedal fully depressed throughout the
braking process, despite the fact that
the pedal is pulsating. Do not reduce
the pressure on the pedal.
After starting-off, the system performs a self-test which may be audible.
Control indicator u 3 87.
Fault
If control indicator u does not go out
a few seconds after the ignition is switched on, or if it illuminates whiledriving, there is a fault in the ABS.
Control indicator F 3 86 may also
illuminate in the instrument cluster together with a corresponding
message in the Driver Information
Centre (DIC). The brake system
remains operational but without ABS
regulation.9 Warning
If there is a fault in the ABS, the
wheels may be liable to lock due
to braking that is heavier than
normal. The advantages of ABS are no longer available. During
hard braking, the vehicle can no longer be steered and may
swerve.
If control indicators u, F , R 3 86
and C 3 86 illuminate, there is a fault
in the braking system. A
corresponding message also
appears in the DIC 3 90. Have the
cause of the fault remedied by a
workshop.
Vehicle messages 3 91.
