ABS (Anti-lock Braking System)
Important safety notes i
Observe the "Important safety notes"
section (Y page 60). G
WARNING
If the ABS malfunctions, other driving 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 the steering
capability and extending the braking distance. G
WARNING
If ABS is faulty, the wheels could lock when
braking. The steerability and braking
characteristics may be severely impaired.
Additionally, further driving safety systems
are deactivated. There is an increased danger
of skidding and accidents.
Drive on carefully. Have ABS checked
immediately at a qualified specialist
workshop.
ABS regulates brake pressure in such a way
that the wheels do not lock when you brake.
This allows you to continue steering the
vehicle when braking.
Provided that the differential locks are not
active, ABS works from a speed of about
5 mph (8 km/h) upwards, regardless of road-
surface conditions. ABS works on slippery
surfaces, even if you only brake gently.
The yellow 0025ABS warning lamp in the
instrument cluster lights up when the ignition
is switched on. It goes out when the engine is
running.
Braking If ABS intervenes when braking, you will feel
a pulsing in the brake pedal. X
If ABS intervenes: continue to depress the
brake pedal vigorously until the braking
situation is over.
X To make a full brake application:
depress the brake pedal with full force.
The pulsating brake pedal can be an
indication of hazardous road conditions, and
functions as a reminder to take extra care
while driving.
Off-road ABS If the
LOW RANGE shift range is selected by
the transfer case, (Y page 194), an ABS
system specifically suited to off-road terrain
is automatically activated.
At speeds below 37 mph (60 km/h), the front
wheels lock cyclically during braking. The
digging-in effect achieved in the process
reduces the stopping distance on off-road
terrain. This limits steering capability. BAS (Brake Assist System)
i Observe the "Important safety notes"
section (Y page 60). G
WARNING
If BAS is malfunctioning, the braking distance
in an emergency braking situation is
increased. There is a risk of an accident.
In an emergency braking situation, depress
the brake pedal with full force. ABS prevents
the wheels from locking.
BAS operates in emergency braking
situations. If you depress the brake pedal
quickly, BAS automatically boosts the braking
force, thus shortening the stopping distance.
X Keep the brake pedal firmly depressed until
the emergency braking situation is over.
ABS prevents the wheels from locking.
The brakes will function as usual once you
release the brake pedal. BAS is deactivated. Driving safety systems
61Safety Z 

Adaptive brake lights
If you brake sharply from a speed of more
than 30 mph (50 km/h) or if braking is
assisted by BAS, the brake lamps flash
rapidly. In this way, traffic traveling behind
you is warned in an even more noticeable
manner.
If you brake sharply from a speed of more
than 45 mph (70 km/h) to a standstill, the
hazard warning lamps are activated
automatically. If the brakes are applied again,
the brake lamps light up continuously. If you
drive faster than 6 mph (10 km/h), the hazard
warning lamps are deactivated automatically.
You can also switch off the hazard warning
lamps using the hazard warning button
(Y page 104). ESP
®
(Electronic Stability Program)
Important safety notes i
Observe the "Important safety notes"
section (Y page 60). G
WARNING
If ESP ®
is malfunctioning, ESP ®
is unable to
stabilize the vehicle. Additionally, further
driving safety systems are deactivated. This
increases the risk of skidding and an accident.
Drive on carefully. Have ESP ®
checked at a
qualified specialist workshop.
! Only operate the vehicle for a maximum
of ten seconds on a brake test
dynamometer. Switch off the ignition.
Application of the brakes by ESP ®
may
otherwise destroy the brake system.
! A function or performance test should
only be carried out on a two-axle
dynamometer. Before you operate the
vehicle on such a dynamometer, please
consult a qualified workshop. You could
otherwise damage the drive train or the
brake system. ESP
®
monitors driving stability and traction.
Traction is the power transmission between
the tires and the road surface.
ESP ®
is deactivated if the 00BBwarning lamp
in the instrument cluster lights up
continuously when the engine is running.
If the 00E5 warning lamp and the 00BB
warning lamp are lit continuously, ESP ®
is not
available due to a malfunction.
Observe the information on warning lamps
(Y page 247) and any display messages that
appear in the instrument cluster
(Y page 221).
If ESP ®
detects that the vehicle is deviating
from the direction desired by the driver, one
or more wheels are braked to stabilize the
vehicle. If necessary, the engine output is also
modified to keep the vehicle on the desired
course within physical limits. ESP ®
assists
the driver when pulling away on wet or
slippery roads. ESP ®
can also stabilize the
vehicle during braking.
If ESP ®
intervenes, the 00E5warning lamp
flashes in the instrument cluster.
If ESP ®
intervenes:
X Do not deactivate ESP ®
under any
circumstances.
X Only depress the accelerator pedal as far
as necessary when pulling away.
X Adapt your driving style to suit the
prevailing road and weather conditions.
i Only use wheels with the recommended
tire sizes. Only then will ESP ®
function
properly.
i If differential locks are switched on, ABS,
BAS and ESP ®
switch themselves off
automatically.
4ETS (Electronic Traction System) Traction control remains active if you
deactivate ESP ®
