On slippery road surfaces, the ABS will
respond even to light brake pressure.
The ABS indicator lamp ! in the
instrument cluster comes on when you switch
on the ignition. It goes out when the engine
is running.
Braking
At the instant one of the wheels is about to
lock up, a slight pulsation can be felt in the
brake pedal. The pulsation indicates that the
ABS is in the regulating mode.
X
Keep firm and steady pressure on the brake
pedal while you feel the pulsation.
Continuous, steady brake pedal pressure
yields the advantages provided by the ABS,
namely braking power and the ability to steer
the vehicle.
The pulsating brake pedal can be an
indication of hazardous road conditions and
functions as a reminder to take extra care
while driving.
Emergency brake maneuver
X
Keep continuous full pressure on the brake
pedal.
If the ABS malfunctions, other driving safety
systems such as the BAS or the ESP
®
are also
switched off. Observe indicator and warning
lamps that may come on as well as messages
in the multifunction display that may appear.
If the ABS malfunctions, the wheels may lock
during hard braking, reducing steering
capability and extending the braking distance.
LOW-RANGE ABS
During off-road driving, a special low-range
system for the ABS is operational with the
transfer case in position LOW (
An improved braking action (dig-in effect) is
obtained for vehicles speeds of up to 37 mph
(60 km/h) through a change in the ABS
control function.
G
Observe Safety notes, see page 52.
The Brake Assist System (BAS) operates in
emergency situations. If you apply the brakes
very quickly, the BAS provides full brake
boost automatically, thereby potentially
reducing the braking distance.
X
Apply continuous full braking pressure until
the emergency braking situation is over.
The ABS will prevent the wheels from
locking.
When you release the brake pedal, the brakes
function again as normal. The BAS is then
deactivated.
If the BAS malfunctions, the brake system still
functions, but without the additional brake
boost available that the BAS would normally
provide in an emergency braking maneuver.
Therefore, the braking distance may increase.
G
Observe Safety notes, see page 52.
The Electronic Brake Booster (EBB) enhances
braking effectiveness by allowing the rear
brakes to supply a greater proportion of the
braking effort in straight-line braking without
a loss of vehicle stability.
If the EBB malfunctions, the brake system is
still functioning. However, the rear wheels
may lock up during hard braking. You may to
lose control over the vehicle and possibly
cause an accident. Adjust your driving style to
the non-operating status of the EBB.
