Overview of driving safety systems
In this section, you will find information about
the following driving safety systems:
RABS (Anti-lockBrakingSystem)
(Ypage 61)
RBAS (BrakeAssistSystem) (Ypage 62)
RCOLLISION PREVENTION ASSIST (distance
warning function and adaptive Brake
Assist) (Ypage 62)
RESP®(ElectronicStabilityProgram)
(Ypage 65)
REBD (ElectronicBrake forceDistribution)
(Ypage 69)
RADAPTIVE BRAKE (Ypage 69)
RSTEER CONTROL (Ypage 69)
Important safety notes
If you fail to adapt yourdriving 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 yourdriving style to
suitthe prevailing road, weather and traffic
conditions and maintainasafe 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. Pay particular attention
to the informationregarding tires,
recommended minimum tire tread depths
etc.inthe "Wheels and tires" section
(Ypage 312).
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-lockBraking System)
General information
ABS regulates brake pressure in such a way
thatthe wheels do not lock when you brake.
This allows you to continue steering the
vehicle when braking.
TheABS 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 for driving safety systems
(Ypage 61).

!When testing the electric parking brake
on a braking dynamometer, switch off the
ignition. Application of the brakes by
ESP®may otherwise destroy the brake
system.
!Vehicles with 4MATIC: switch off the
ignition when the electric parking brake is
being tested on a brake dynamometer.
Application of the brakes by ESP®may
otherwise destroy the brake system.
!Vehicles with 4MATIC: function or
performance tests may only be carried out
on a 2-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.
!Do not tow vehicles with 4MATIC with the
front or rear axle raised.
Vehicles without 4MATIC: when towing your
vehicle with the front axle raised, it is
important that you observe the notes on
ESP®(Ypage 307).
Vehicles with 4MATIC: when towing your
vehicle with both axles on the ground, it is
important that you observe the notes on
ESP®(Ypage 307).
ESP®is deactivated if theESP®OFF
warning lamp in the instrument cluster lights
up continuously when the engine is running.
If theESP®warning lamp and the
ESP®OFF warning lamp are lit
continuously, ESP®is not available due to a
malfunction.
Observe the information on warning lamps
(Ypage 244) and displaymessages which
may be shown in the instrument cluster
(Ypage 213).
iOnly use wheels with the recommended
tire sizes. Only then will ESP®function
properly.
Characteristics of ESP®
General information
If theESP warning lamp goes out before
beginning the journey, ESP®is automatically
active.
If ESP®intervenes, theESP®warning
lamp flashes in the instrument cluster.
If ESP®intervenes:
XDo not deactivate ESP®under any
circumstances.
XOnly depress the accelerator pedal as far
as necessary when pulling away.
XAdapt your driving style to suit the
prevailing road and weather conditions.
ECO start/stop function
The ECO start/stop function switches the
engine off automatically when the vehicle
stops moving. 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 enginewas switched
off, ESP®remains deactivated when the
engine is switched on again.
Deactivating/activating ESP®(AMG

Important safety notes
iObserve the "Important safety notes"
section(Ypage 61).
You can select between the following states
of ESP®:

Rto soft, light and thin objects, e.g. small
fingers
Rover the last 1/6 in(4 mm) of the closing
movement
Rduring resetting
Rwhen closing the side window again
manually immediately after automatic
reversing
This means that the reversing feature cannot
prevent someone being trapped in these
situations. There is a risk of injury.
Make sure that no body parts are in close
proximity during the closing procedure. If
someone becomes trapped, press the switch
to open the side window again.
