Emergency brake maneuver

̈

Keep continuous full pressure on the
brake pedal.

Off-road – ABS

With the off-road driving program switched
on (

page 268), the ABS designed for

off-road use is automatically activated.

When applying the brakes at speeds below
approximately 18 mph (30 km/h), the
front wheels are locked cyclically to short-
en the braking distance (dig-in effect). This
affects steering the vehicle.

For more information, see “Practical hints”
(

page 413).

BAS

The Brake Assist System (BAS) operates in
emergency situations. If you apply the
brakes very quickly, the BAS automatically
provides full brake boost, thereby poten-
tially reducing braking distance.

̈

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.

Warning!

G

When the ABS is malfunctioning, the BAS,

the ESP

®

, and the 4-ETS are also switched

off. The basic driving and braking functions

are still available.

When the ABS is malfunctioning, the wheels

may lock during hard braking, reducing

steering capability and extending the brak-

ing distance.

Warning!

G

The ABS cannot prevent the natural laws of

physics from acting on the vehicle, nor can

it increase braking or steering efficiency be-

yond that afforded by the condition of the

vehicle brakes and tires or the traction

afforded. The ABS cannot prevent acci-

dents, including those resulting from

excessive speed in turns, following another

vehicle too closely, or hydroplaning. Only a

safe, attentive, and skillful driver can pre-

vent accidents. The capabilities of an ABS

equipped vehicle must never be exploited in

a reckless or dangerous manner which

could jeopardize the user’s safety or the

safety of others.

Warning!

G

If the BAS is malfunctioning, the brake sys-

tem is still functioning, but without the addi-

tional brake boost available that BAS would

normally provide in an emergency braking

maneuver. Therefore, the braking distance

may increase.
