ABS (Anti-lock Braking System)
General notes ABS regulates brake pressure in such a way
that the wheels do not lock when you brake.
This allows you to continue steering the vehi-
cle when braking.
The ò warning lamp in the instrument clus-
ter lights up when the ignition is switched on.
The lamp goes out when the engine starts run-
ning.
Important safety notes Observe the important safety guidelines for
the driving safety system (
Y page
66).
ABS works from a speed of about 5 mph
(8 km/h), regardless of road-surface condi-
tions. ABS works on slippery surfaces, even
when you only brake gently. G
WARNING
If ABS is faulty, the wheels could lock when
braking. The steerability and braking charac-
teristics may be severely impaired. Addition-
ally, further driving safety systems are deac-
tivated. There is an increased danger of
skidding and accidents.
Drive on carefully. Have ABS checked imme-
diately at a qualified specialist workshop.
If ABS is malfunctioning, the ò warning
lamp

(Y page 230) lights up while the engine
is running and the display shows a message:
R on vehicles without steering wheel buttons
(Y page 196)
R on vehicles with steering wheel buttons
(Y page 210)
BAS, Hill Start Assist and ESP ®
and its driving
safety systems and other driving systems also
fail. Observe the notes on the ò warning
lamp and the display messages.
Braking If ABS intervenes when braking, you will feel a
pulsating in the brake pedal.
The pulsating brake pedal can be an indication
of hazardous road conditions and functions as
a reminder to take extra care while driving. X
If ABS intervenes: continue to depress the
brake pedal with force until the braking sit-
uation is over.
X To make a full brake application: depress
the brake pedal with full force. BAS (Brake Assist System)
General notes BAS operates in emergency braking situations.
If you depress the brake pedal quickly, BAS
automatically boosts the braking force, thus
shortening the stopping distance.
Important safety notes Observe the important safety guidelines for
the driving safety system

(Y page 66). G
WARNING
If BAS is malfunctioning, the braking dis-
tance 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.
If BAS is malfunctioning, the ÷ warning
lamp lights up while the engine is running
(Y page

230) and the display shows a mes-
sage:
R on vehicles without steering wheel buttons
(Y page 200)
R on vehicles with steering wheel buttons
(Y page 214)
Braking 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

to stabilize the vehicle/trailer combination in
this situation.
ESP
®
trailer stabilization is activated above
speeds of about
40 mph (65 km/h).
If ESP ®
is switched off or deactivated because
of a malfunction, the trailer stabilization sys-
tem will not function.
Crosswind Assist Observe the important safety guidelines for
the driving safety system (Y page

66).
Strong crosswind gusts can impair the road-
holding of your vehicle when driving straight
ahead. The Crosswind Assist function integra-
ted in ESP ®
reduces these impairments.
Depending on the direction and intensity of
the side wind, Crosswind Assist intervenes
automatically. ESP ®
intervenes with stabilizing
braking to assist you in keeping the vehicle in
the lane. When Crosswind Assist intervenes,
the display shows the traffic sign for strong
side winds and the Crosswind Assist mes-
sage.
Crosswind Assist is activated automatically
above a vehicle speed of approx. 50 mph
(80 km/h) when the vehicle is driving straight
ahead or cornering gently.
Crosswind Assist does not react in the follow-
ing situations:
R in the event of severe jolts and vibrations,
e.g. when driving over uneven surfaces or
potholes
R when road adhesion is reduced, e.g. on
snow or ice or when hydroplaning
Crosswind Assist does not work if ESP ®
is
deactivated or disabled because of a malfunc-
tion. Theft deterrent locking system
