152 Driving and operationFor vehicles with manual transmission
automated 3, the control indicator flashes
for a few seconds when the ignition is
turned off when the hand brake is not
applied. Anti-lock brake system (ABS
u)
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 though a
pulse in the brake pedal and the noise of
the regulation process.
For optimum braking, keep the brake
pedal fully depresse d throughout the
braking process, despite the fact that the
pedal is pulsating. Do not reduce the
pressure on the pedal.
Picture no: 17895s.tif
Control indicator u for ABS
It illuminates for a few seconds when
ignition is switched on. Once the control
indicator goes out, the system is ready for
operation.
If the control indica tor does not go out
after a few seconds, or if it illuminates while
driving, there is a fault in the ABS. The
brake system remains operational without
ABS regulation.
Adaptive brake lamp 3
During full-on braking, all three brake
lamps flash for the duration of ABS control. Self testing
When the engine is started and the vehicle
starts off, the system performs a self-check,
which may be audible.
Fault
Have cause of fault remedied by a
workshop. The system’s integrated self
diagnostics allow faults to be quickly
remedied.
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.

The following fuses are Maxi fuses.
Bulb replacement Switch off the ignition and switch off the
relevant switch or close the doors.
Only hold a new bulb at the base! Do not
touch the bulb glass with your bare hands.
Replace the bulb, checking that the data
on the base matches that of the defective
bulb.
To replace a bulb, pull off the relay box on
the left side. On the right side, pull off the
air hose to the air filter.

Brake fluid The brake fluid level must be between
theMIN and the MAX marks. When topping up, ensure maximum
cleanliness as contamination of the brake
fluid can lead to func
tion problems in the
braking system.
Only use approved high performance
brake fluids. Only us e brake fluid DOT4.
After correcting the brake fluid level, have
the cause of the loss of brake fluid
remedied by a workshop. Brake fluid change
Brake fluid is hygroscopic, i.e. it absorbs
water. If the brakes become hot, such as
when driving on long downhill stretches,
vapour bubbles can occur in the water,
which can have an extremely adverse
effect on braking power (depending on the
proportion of water).
Keep to the specified intervals.
9 Warning
Brake fluid is poisonous and corrosive.
Do not allow it to come into contact with
eyes, skin, fabrics or painted surfaces.
9 Warning
Have the brake fluid change performed
by a workshop. Please comply with the
legal environmental and health
regulations – concerning the disposal
of brake fluid.
