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 277).
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 222) lights up while the engine is run-
ning and the display shows a message:

Safety

Depending on the equipment in the vehicle, you
can activate or deactivate ESP®when the
engine is running by using the åbutton or by
using the on-board computer:
Ron vehicles without steering wheel buttons
(Ypage 174)
Ron vehicles with steering wheel buttons
(Ypage 184)
å button (equipment-dependent)
XTo activate/deactivate: when the engine is
running, press the åbutton.
The å warning lamp in the instrument
cluster lights up when ESP
®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.

Replacing bulbs
Important safety notes
GWARNING
Bulbs, lamps and connectors can get very hot
when operating. If you change a bulb, you
could burn yourself on these components.
There is a risk of injury.
Allow these components to cool down before
changing a bulb.
!Make sure the bulbs are always securely
installed.
The bulbs and lamps are an essential compo-
nent of vehicle safety. You must therefore make
sure that these function correctly at all times.
Have the headlamp setting checked regularly.
RAlways switch off the ignition before replacing bulbs in the lighting system. This will prevent
a short circuit.
RWear gloves and eye protection when chang-
ing a bulb.
RDo not use a bulb that has been dropped or
that has scratches on its glass tube. The bulb
could may explode.
RA bulb could explode if:
-you touch it
-it is hot
-you drop it
-you scratch or score it
RMarks on the glass tube shorten the operating
life of a bulb. Do not touch the glass tube with
your bare hands. If necessary, clean the glass
tube when cold with alcohol or spirit. Then rub
off the glass tube with a clean, lint-free cloth.
RMake sure that bulbs are protected from
moisture when operating and that they do not
come into contact with liquids. Make sure
that seals are seated correctly and replace
damaged seals.
RCheck the contacts for signs of corrosion and
clean these if required.
ROnly operate bulbs in closed lamps which
have been designed for this purpose.
ROnly use spare bulbs of the same type, with
the prescribed voltage and the correct wat-
tage.
RIf the new bulb does not light up, consult a
qualified specialist workshop.
RHave lamps with LED bulbs repaired at a quali- fied specialist workshop only.
RHave the bulbs of the following lamps
replaced at a qualified specialist workshop
only:
-the additional brake lamps
-the license plate lighting

Breaking-in notes
Important safety notes
In certain driving and driving safety systems, the
sensors adjust automatically while a certain dis-
tance is being driven after the vehicle has been
delivered or after repairs. Full system effective- ness is not reached until the end of this teach-in
procedure.
New or replaced brake pads and brake discs
only reach their optimal braking effect after a
few hundred kilometers of driving. Until then,
compensate for this by applying greater force to
the brake pedal.
The first 1000 miles (1500 km)
For the service life and economy of your vehicle
it is crucial that you break in the engine with due
care.
RTherefore, protect the engine for the first
1000 miles (1500 km) by driving at varying
vehicle and engine speeds.
RAvoid overstraining the vehicle and high
engine speeds during this period, e.g. driving
at full throttle. Do not exceed Øof the per-
missible maximum speed for each gear.
RDo not change down a gear manually in order to brake.
RTry to avoid depressing the accelerator pedal
beyond the pressure point (kickdown).
After 1000 miles (1500 km), you can increase
the engine speed gradually and accelerate the
vehicle to full speed.
iYou should also observe these notes on
breaking-in if the engine or parts of the drive
train on your vehicle have been replaced.

Important safety notes
GWARNING
Flammable materials introduced through
environmental influence or by animals can
ignite if in contact with the exhaust system or
parts of the engine that heat up. There is a risk
of fire.
Carry out regular checks to make sure that
there are no flammable foreign materials in
the engine compartment or in the exhaust
system.
GWARNING
If you switch off the ignition while driving,
safety-relevant functions are only available
with limitations, or not at all. This could affect, for example, the power steering and the brake
boosting effect. You will require considerably
more effort to steer and brake. There is a risk
of an accident.
Do not switch off the ignition while driving.
GWARNING
If the parking brake has not been fully
released when driving, the parking brake can:
Roverheat and cause a fire
Rlose its hold function.
There is a risk of fire and an accident. Release
the parking brake fully before driving off.
!Warm up the engine quickly. Do not use the
engine's full performance until it has reached
operating temperature.
Only shift the automatic transmission to the
desired drive position when the vehicle is sta-
tionary.
Where possible, avoid spinning the drive
wheels when pulling away on slippery roads.
You could otherwise damage the drive train.
