Braking
At the instant one of the wheels is about to
lock up, a slight pulsation can be felt in the
brake pedal, indicating that the ABS is in
the regulating mode.
Keep firm and steady pressure on the
brake pedal while experiencing the pul-
sation.
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 indica-
tion of hazardous road conditions and
functions as a reminder to take extra care
while driving.
Emergency brake maneuver
Keep continuous full pressure on the
brake pedal.
i
With the ABS malfunctioning, the BAS,
the ESP, and the 4-ETS are also
switched off.
Normal driving and braking functions
are still available.

LOW RANGE– ABS
During off-road driving, a special low range
system for the ABS is operational with
transmission in LOW RANGE mode
( page 127).
When applying the service brakes at
speeds below approximately
18 mph (30 km/h), the front wheels are
locked cyclically to shorten the braking
distance (dig-in effect). This affects steer-
ing the vehicle.
