Belt warning for the driver and front
passenger The 7 seat belt warning lamp in the
instrument cluster is a reminder for all
occupants to fasten their seat belts.
Regardless
of whether the driver's and front-
passenger seat belts have already been
fastened, the 7 seat belt warning lamp
lights up for six seconds each time the engine
is started. It then goes out once the driver and
the front passenger have fastened their seat
belts.
If the driver and/or front passenger have not
fastened their seat belts after the engine has
been started, an additional warning tone
sounds. This warning tone switches off after
approximately six seconds or once the
driver's seat belt is fastened. If after six seconds, the driver or front
passenger have not fastened their seat belts
and the doors are closed:
R
the 7 seat belt warning lamp remains
illuminated
as long as either the driver's or
front-passenger seat belt is not fastened
R and if vehicle speed once exceeds
15 mph (25 km/h), the 7 seat belt
warning lamp lights up. A warning tone also
sounds with increasing intensity for a
maximum of 60 seconds or until the driver
or front-passenger seat belt has been
fastened.
If the driver or front-passenger seat belt is
unfastened while the vehicle is in motion, the
7 seat belt warning lamps light up and a
warning tone sounds again.
The warning tone ceases even if the driver or
front-passenger seat belt has still not been
fastened after 60 seconds. The 7 seat belt
warning lamp stops flashing but remains
illuminated.
After the vehicle comes to a standstill, the
warning tone is reactivated and the 7 seat
belt warning lamp flashes again if the vehicle
speed again exceeds 15 mph (25 km/h).
The 7 seat belt warning lamp only goes
out if:
R both the driver and the front passenger
have fastened their seat belts.
or
R the vehicle is stationary and a door is open.

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 ! ABS 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 199), 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

Safety Z
Adaptive brake lamps
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 å warning lamp
in the instrument cluster lights up
continuously when the engine is running.
If the ÷ warning lamp and the å
warning lamp are lit continuously, ESP ®
is not
available due to a malfunction.
Observe the information on warning lamps
(Y page 252) and any display messages that
appear in the instrument cluster
(Y page 226).
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 ÷ warning 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.

X
If appropriate for the driving conditions,
engage the LOW RANGE off-road gear
(Y page 199).
Traction control is part of ESP ®
.
Traction control brakes the drive wheels
individually if they spin. This enables you to
pull
away and accelerate on slippery surfaces,
for example if the road surface is slippery on
one side. In addition, more drive torque is
transferred to the wheel or wheels with
traction.
Traction control remains active if you
deactivate ESP ®

At speeds above approximately 37 mph
(60 km/h), traction control is no longer
active.
Traction control brakes the drive wheels

Deactivating/activating ESP ®G
WARNING
If you deactivate ESP ®
, ESP ®
no longer
stabilizes the vehicle. There is an increased
risk of skidding and an accident.
Only deactivate ESP ®
in the situations
described in the following.
! Avoid spinning the driven wheels for an
extended period with ESP ®
deactivated.
You
could otherwise damage the drivetrain. X
To deactivate: press button : until the
å warning lamp lights up in the
instrument cluster.
X To activate: press button : until the
å warning lamp goes out in the
instrument cluster.
ESP ®
is activated automatically when the
engine is started.
i Vehicles with the ECO start/stop
function: the ECO start/stop function
automatically
switches the engine off when
the vehicle comes to a stop. The engine
starts automatically when the driver wants
to pull away again. ESP ®
remains in its
previously selected status. Example: if
ESP ®
was deactivated before the engine
was switched off, ESP ®
remains
deactivated when the engine is switched on
again.
It may be best to deactivate ESP ®
in the
following situations:
R when using snow chains
R in deep snow
R on sand or gravel
If you deactivate ESP ®
:
R ESP ®
no longer improves driving stability.
R the engine's torque is no longer limited and
the drive wheels can spin. The spinning of
the wheels results in a cutting action, which
provides better grip.
R traction control is still activated. Driving safety systems

R
ESP ®
still provides support when you
brake.
R and are driving at above
37 mph
(60 km/h), ESP ®
still intervenes when one
wheel reaches its grip limit even though it
is switched off.
i If ESP ®
is deactivated and one or more
wheels start to spin, the ÷ warning lamp
in the instrument cluster flashes. In such
situations, ESP ®
will not stabilize the
vehicle.
i If ESP ®
is deactivated, it is automatically
reactivated when you drive faster than
37 mph (60 km/h) or if a predefined lateral
acceleration threshold has been exceeded.
Trailer stabilization G
WARNING
If road and weather conditions are poor,
trailer
stabilization will not be able to prevent
the vehicle/trailer combination from
swerving. Trailers with a high center of gravity
can tip over before ESP ®
can detect this.
There is a risk of an accident.
Always adapt your driving style to the
prevailing road and weather conditions.
Trailer stabilization does not work if ESP ®
is
deactivated because of a malfunction.
If your vehicle with trailer (vehicle/trailer
combination) begins to lurch, you can only
stabilize the vehicle/trailer combination by
depressing the brake firmly.
In this situation, ESP ®
assists you and can
detect if the vehicle/trailer combination
begins to lurch. ESP ®
slows the vehicle down
by braking and limiting the engine output until
the vehicle/trailer combination has
stabilized.
Trailer stabilization is active above speeds of
about 37 mph (60 km/h). EBD (electronic brake force
distribution)
i Observe the "Important safety notes"
section ( Y page 60). G
WARNING
If EBD has malfunctioned, the rear wheels can
still lock, e.g. under full braking. This
increases
the risk of skidding and an accident.
You should therefore adapt your driving style
to the different handling characteristics. Have
the brake system checked at a qualified
specialist workshop.
Observe information regarding indicator and
warning lamps ( Y page 250) as well as
display messages ( Y page 228).
EBD monitors and controls the brake
pressure on the rear wheels to improve
driving stability while braking. ADAPTIVE BRAKE
