Important safety notes
If you fail to adapt your driving style or
become distracted, the driving safety
systems can neither reduce the risk of
accident nor override the laws of physics.
Driving safety systems are merely aids
designed to assist driving. You are
responsible for the distance to the vehicle in
front, for vehicle speed and for braking in
good time. Always adapt your driving style to
suit the prevailing road and weather
conditions and maintain a safe distance from
the vehicle in front. Drive carefully.
iThe driving safety systems described only
work as effectively as possible when there
is adequate contact between the tires and
the road surface. Please pay special
attention to the notes on tires,
recommended minimum tire tread depths,
etc. (Ypage 404).
In wintry driving conditions, always use
winter tires (M+S tires) and if necessary,
snow chains. Only in this way will the
driving safety systems described in this
section work as effectively as possible.
ABS (Anti-lock Braking System)
General information
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.
The%ABS warning lamp in the instrument
cluster lights up when the ignition is switched
on. It goes out when the engine is running.
Important safety notes
iObserve the "Important safety notes"
section (Ypage 67).
GWARNING
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.
When ABS is malfunctioning, other systems,
including driving safety systems, will also
become inoperative. Observe the information
on the ABS warning lamp (Ypage 326) and
display messages which may be shown in the
instrument cluster (Ypage 291).
ABS works from a speed of about 5 mph
(8 km/h), regardless of road-surface
conditions. ABS works on slippery surfaces,
even when you only brake gently.
Braking
XIf ABS intervenes:continue to depress the
brake pedal vigorously until the braking
situation is over.
XTo make a full brake application:
depress the brake pedal with full force.
If ABS intervenes when braking, you will feel
a pulsing in the brake pedal.

Ra vehicle traveling in front on a different line
relative to the center of your vehicle
Rnew vehicles or after the COLLISION
PREVENTION ASSIST system has been
serviced
Observe the notes in the section on
breaking-in (Ypage 166).
Following damage to the front end of the
vehicle, have the configuration and operation
of the radar sensor checked at a qualified
specialist workshop. This also applies to
collisions at low speeds where there is no
visible damage to the front of the vehicle.
ESP®(Electronic Stability Program)
General notes
iObserve the "Important safety notes"
section (Ypage 67).
ESP®monitors driving stability and traction,
i.e. power transmission between the tires and
the road surface.
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. 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.
4ETS (Electronic Traction System)
4ETS 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, even if you
deactivate ESP®.
In appropriate driving situations, activate the
off-road program (Ypage 258).
Off-road 4ETS (Electronic Traction
System)
A 4ETS system specifically suited to off-road
terrain is activated automatically once the off-
road program is activated (Ypage 258).
Important safety notes
GWARNING
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®is deactivated if the

The spinning of the wheels results in a
cutting action for better traction on loose
surfaces.
Rtraction control is still activated.
RESP®still provides support when you
brake.
Off-road ESP®
An ESP®system specifically suited to off-road
terrain is activated automatically once the off-
road program is activated (Ypage 258).
Off-road ESP®intervenes with a delay if there
is oversteering or understeering, thus
improving traction.
ESP®trailer stabilization
General information
ESP®trailer stabilization is not available in
AMG vehicles.
If your vehicle/trailer combination begins to
swerve, ESP®assists you in this situation.
ESP®slows the vehicle down by braking and
limiting the engine output until the vehicle/
trailer combination has stabilized.
Important safety notes
GWARNING
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.
If your vehicle with trailer (vehicle/trailer
combination) begins to lurch, you can only
stabilize the vehicle/trailer combination by
depressing the brake firmly.
Trailer stabilisation is active above speeds of
about 37 mph (60 km/h).
ESP®trailer stabilization does not work if
ESP®is deactivated or disabled because of a
malfunction.
Crosswind driving assistance
General information
Strong crosswinds can cause your vehicle to
deviate from a straight course. The crosswind
driving assistance function integrated into
ESP®significantly reduces these effects.
ESP®intervenes automatically according to
the direction and intensity of the crosswinds
affecting your vehicle.
ESP stabilities the vehicle with braking
interventions to assist you in keeping the
vehicle in the lane.
Crosswind driving assistance is active at
vehicle speeds above 50 mph (80 km/h)
when driving straight ahead or cornering
gently.
Important safety notes
Crosswind driving assistance does not work
if ESP®is deactivated or disabled because of
a malfunction.
EBD (electronic brake force
distribution)
General information
EBD monitors and controls the brake
pressure on the rear wheels to improve
driving stability while braking.
Important safety notes
iObserve the "Important safety notes"
section for driving safety systems
(Ypage 67).
GWARNING
If EBD has malfunctioned, the rear wheels can
still lock, e.g. under full braking. This
increases the risk of skidding and an accident.
