Pets in the vehicle
GWARNING
If you leave animals unattended or unsecured
in the vehicle, they could press buttons or
switches, for example.
As a result, they could:
Ractivate vehicle equipment and become
trapped, for example
Ractivate or deactivate systems, thereby
endangering other road users
Unsecured animals could also be flung around
the vehicle in the event of an accident or sud-
den steering or braking, thereby injuring vehi-
cle occupants. There is a risk of an accident
and injury.
Never leave animals unattended in the vehi-
cle. Always secure animals properly during
the journey, e.g. use a suitable animal trans-
port box.
Driving safety systems
Overview
In this section, you will find information about
the following driving safety systems:
REBD ( Electronic Brake Force Distribution)
RABS ( Anti-lock Braking System)
RBAS ( Brake Assist System)
RESP®(E lectronic Stability Program)
Important safety notes
If you fail to adapt your driving style or if you are
inattentive, the driving safety systems can nei-
ther 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, braking in good time
and for staying in your lane. Always adapt your driving style to the prevailing road and weather
conditions and maintain a sufficient, safe dis-
tance from other road users. Drive carefully.
Please note that the driving safety systems
described only work optimally when:
Rthere is adequate contact between the tires
and the road surface
Ryou use winter tires (M+S tires), with snow
chains if necessary, when the road conditions
are wintry
Rthe speed information determined by the
vehicle is within the legally prescribed display
accuracy
Pay particular attention to the information
regarding tires, tire tread and winter operation
under "Wheels and tires" (
Ypage 279).
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 vehicle when
braking.
The ò warning lamp in the instrument cluster
lights up when the ignition is switched on. The
lamp goes out when the engine starts running.
Important safety notes
Observe the important safety guidelines for the
driving safety system (Ypage 64).
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.
GWARNING
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 skid-
ding and accidents.
Drive on carefully. Have ABS checked imme-
diately at a qualified specialist workshop.
If ABS is malfunctioning, the òwarning lamp
(
Ypage 224) lights up while the engine is run-
ning and the display shows a message:

Ron vehicles without steering wheel buttons
(Ypage 192)
Ron vehicles with steering wheel buttons
(Ypage 206)
BAS, Hill Start Assist and ESP®and its driving
safety systems and other driving systems also
fail. Observe the notes on the òwarning
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.
XIf ABS intervenes: continue to depress the
brake pedal with force until the braking sit-
uation is over.
XTo 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 (Ypage 64).
GWARNING
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.
If BAS is malfunctioning, the ÷warning lamp
lights up while the engine is running
(
Ypage 224) and the display shows a message:
Ron vehicles without steering wheel buttons
(Ypage 196)

(Ypage 210)
Braking
XKeep 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.
EBD (electronic brake force distribu-
tion)
General notes
EBD monitors and controls the brake pressure
to the rear wheels. This enables EBD to improve
handling during braking.
Important safety notes
Observe the important safety guidelines for the
driving safety system (Ypage 64).
GWARNING
If EBD is malfunctioning, the rear wheels can
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 spe-
cialist workshop.
If EBD is malfunctioning, the $warning lamp
(
Ypage 223) lights up while the engine is run-
ning and the display shows a message.

Other driving systems and driving safety sys-
tems then also fail.
ESP®(Electronic Stability Program)
General notes
ESP®monitors driving stability and detects a
tendency of the vehicle to understeer or over-
steer (skidding) in good time. 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 out-

Z

put is also modified to keep the vehicle on the
desired course within physical limits. ESP®can
also stabilize the vehicle during braking.
ESP
®also monitors traction, i.e. power trans-
mission between the tires and the road surface.
The integrated traction control supports you
when pulling away or accelerating on wet, slip-
pery or slick roads. Should the drive wheels spin,
traction control brakes them individually. In
addition, greater drive torque is transmitted to
the wheel or wheels with traction. If traction on
the road surface is not sufficient, even ESP
®will
not allow you to pull away without difficulty. The
type of tires and total weight of the vehicle as
well as the gradient of the road also play a cru-
cial role. Traction control remains active if you
deactivate ESP
®.
If the h warning lamp in the instrument clus-
ter goes out before beginning the journey, ESP
®
is automatically active.
The h warning lamp in the instrument cluster
flashes when ESP
®intervenes:
XDo not deactivate ESP®under any circum-
stances.
Xwhen driving off, apply as little throttle as
possible.
Xadapt your speed and driving style to the pre-
vailing road conditions.
Important safety notes
Observe the important safety guidelines for the
driving safety system (Ypage 64).
GWARNING
If ESP
®is malfunctioning it will not provide
any vehicle stabilization. There is an increased
risk of skidding or of an accident.
Exercise caution when continuing to drive.
Have ESP
®checked at a qualified specialist
workshop.
!Do not run the vehicle on a roller dynamom-
eter (e.g. for performance tests). If you must
operate the vehicle on a roller dynamometer,
please consult a qualified specialist workshop
in advance. You could otherwise damage the
drive train or the brake system.
If ESP
®is malfunctioning, the hwarning
lamp (Ypage 224) lights up continuously while the engine is running and the display shows a
message.
Ron vehicles without steering wheel buttons

ESP®is deactivated if the åwarning lamp in
the instrument cluster is lit when the engine is
running.
Only use wheels with the recommended tire
sizes. Only then will ESP
®function properly.
Deactivating or activating ESP®
GWARNING
If you deactivate ESP
®, ESP®no longer sta-
bilizes the vehicle. There is an increased risk
of skidding and an accident.
Only deactivate ESP
®in the situations descri-
bed in the following.
It may be best to deactivate ESP
®in the follow-
ing situations:
Rwhen using snow chains
Rin deep snow
Ron sand or gravel
Activate ESP®as soon as the situations descri-
bed above no longer apply. Otherwise, ESP®
assistance for stabilizing the vehicle will remain significantly reduced, even if the vehicle starts
to skid.
If you deactivate ESP
®:
Rthe å warning lamp in the instrument clus-
ter lights up
Rthe ÷ warning lamp in the instrument clus-
ter flashes if the wheels are spinning
RESP®assistance for stabilizing the vehicle in
the lower speed range up to approximately

drive wheels are able to spin. The spinning of
the wheels results in a cutting action for bet-
ter traction on loose surfaces

®is deactivated.
Trailer stabilization
Observe the important safety guidelines for the
driving safety system (Ypage 64).
GWARNING
If road and weather conditions are poor,
trailer stabilization will not be able to prevent
the vehicle/trailer combination from swerv-
ing. 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 prevail-
ing road and weather conditions.
ESP
®trailer stabilization counteracts critical
driving situations in good time and thereby pro- vides considerable assistance when driving with
a trailer. Trailer stabilization is part of ESP
®.
If the sensor system and evaluation logic detect
trailer swinging movements, ESP
®trailer stabi-
lization firstly brakes individual vehicle wheels in
a targeted manner. It thus counteracts swinging
movements. If the swinging movements do not
stop, the vehicle is braked until the vehicle/ trailer combination is stabilized. If necessary,
the vehicle's engine output is limited.
If your vehicle with trailer (vehicle/trailer com-
bination) starts to swerve, you will be able to
stabilize the vehicle/trailer combination only by
braking. ESP
®trailer stabilization helps you to
stabilize the vehicle/trailer combination in this
s
ituation.
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 system
will not function.
Crosswind Assist
Observe the important safety guidelines for the
driving safety system (Ypage 64).
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 auto-
matically. ESP
®intervenes with stabilizing brak-
ing 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
message.
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:
Rin the event of severe jolts and vibrations, e.g.
when driving over uneven surfaces or pot-
holes
Rwhen grip is reduced, e.g. on snow or ice or
when hydroplaning
Crosswind Assist does not work if ESP
®is deac-
tivated or disabled because of a malfunction.
