ABS (Anti-lock Brakin gSystem)
General information
ABS regulate sbrake pressure in such awaythat
the wheels do not lock when yo ubrake. This
allows yo utocontinue steering the vehicl ewhen
braking.
The yellow !ABS warning lamp in the instru-
ment cluster lights up when the ignition is
switched on. It goe soutwhen the engine is run-
ning.
ABS works from aspeed of about5m ph
(8 km/h), regardless of road-surface conditions.
ABS works on slippery surfaces, eve nwheny ou

Off-road ABS
An ESP®system specifically suited to off-road
terrain is activated automatically once th eoff-

GWARNING
If ESP
®is malfunctioning, ESP®is unable to
stabilize the vehicle. Additionally, further driv-
ing safety systems are deactivated. This
increases the risk of skiddin gand an accident.
Driv eonc arefully. Have ESP
®checked at a
qualified specialist workshop.
!Only operate the vehicle for amaximum of

erwise destroy the brake system.
!Af unction or performanc etest should only

Beforey ou operate the vehicle on such a
dynamometer, please consult aqualified
workshop. You could otherwise damage the
drive train or the brake system.
If the å ESP
®OFF warning lamp lights up
continuously, ESP®is deactivated.
If the ÷ ESP®warning lamp lights up contin-
uously, ESP®is not available due to amalfunc-
tion.
Observe the information on warning lamps
(
Ypage 191) and display messages which may
be displayed in the instrument cluster
(
Ypage 171). Only use wheels with the recommended tire
sizes. Only then will ESP
®function properly.

flashes in the instrument cluster.
If ESP
®intervenes:
XDo not deactivate ESP®under any circum-
stances.
XOnly depress the accelerator pedal as far as
necessary when pulling away.
XAdapt your drivings tyle to suit the prevailing
road and weather conditions.
ECO start/stop function
The ECO start/stop function switches the

Trailer stabilization
General information
If yourvehicle/trailer combination begins to
swerve, ESP®assists you in this situation. ESP®
slowst he vehicle down by braking and limiting
the engine outputu ntil the vehicle/trailer com-
bination has stabilized.
Important safety notes
GWARNING
If road and weather conditions are poor,
trailers tabilization willn ot be abletoprevent
the vehicle/trailer combination from swerv-
ing. Trailers with ahigh center of gravity can
tip over before ESP
®can detect this. There is
ar isk of an accident.
Alway sadapt you rdriving style to the prevail-
ing road and weather conditions.
If you rvehicle with trailer( vehicle/trailercom-
bination) begins to lurch, you can only stabilize
the vehicle/trailer combination by depressing
the brake firmly.
Trailer stabilization is active above speedso f

Sliding sunroof
Important safety notes
GWARNING
While opening and closing the sliding sunroof, body parts in close proximity could become
trapped. There is arisk of injury.
Make sure that no body parts are in close
proximity during the opening and closing pro-
cedures.
If somebody becomes trapped:
Rrelease the switch immediately, or
Rduring automatic operation, push the
switch briefly in any direction
The opening or closing procedure will be stop- ped.
GWARNING
If children operate the sliding sunroof they
could become trapped, particularly if they are left unsupervised. There is arisk of injury.
When leaving the vehicle, always take the
SmartKey with you and lock the vehicle. Never
leave children unsupervised in the vehicle.
!Only open the sliding sunroof if it is free of
snow and ice. Otherwise, malfunctions may
occur.
Do not allow anything to protrude from the
sliding sunroof. Otherwise, the seals could be
damaged.
!The weather can change abruptly. It could
start to rain or snow. Make sure that the slid- ing sunroof is closed when you leave the vehi-
cle. The vehicle electronics can be damaged if
water enters the vehicle interior.
Resonance noises can occur in addition to the
usual airflow noises when the sliding sunroof is
open. They are caused by minor pressure fluc-
tuations in the vehicle interior. Change the posi-
tion of the sliding sunroof or open aside window
slightly to reduce or eliminate these noises.
