Operating safety and vehicle approval
Important safety notes
GWARNING
If you do not have the prescribed service/
maintenance work or any required repairs
carried out, this can result in malfunctions or system failures. There is a risk of an accident.
Always have the prescribed service/mainte-
nance work as well as any required repairs
carried out at a qualified specialist workshop.
Air bags and pyrotechnic Emergency Tensioning
Devices (ETDs) contain perchlorate material,
which may require special handling and regard
for the environment. The guidelines must be
observed during disposal.
In California, you can find more information on
the Internet at www.dtsc.ca.gov.
Notes on operating the vehicle
There is a risk of damage to the vehicle if:
Rthe vehicle makes contact with the ground,
e.g. on a high curb or a loose road surface
Ryou drive too quickly over an obstacle, e.g. a
curb or a pothole
Ra heavy object hits the underbody or chassis
component
In these or similar situations, the vehicle body/
frame, the underbody, chassis components,
wheels or tires could be damaged even if this is
not visible from the outside. Components that
have been damaged in this way can unexpect-
edly fail or no longer be able to assimilate the
loads occurring in the event of an accident. If the underbody paneling is damaged, flammable
material, such as leaves, grass or twigs, could
collect between the underbody and underbody
paneling. These materials could ignite if they
remain in contact with hot components of the
exhaust system for an extended period.
GWARNING
Flammable material such as leaves, grass or
twigs may ignite if they come into contact with
hot parts of the exhaust system. There is a risk of fire.
Introduction25
Z
Pay particular attention to the information
regarding tires, tire tread and winter operation
under "Wheels and tires" (
Ypage 247).
ABS (Anti-lock Braking System)
Important safety notes
Observe the important safety guidelines for the
driving safety system (Ypage 52).
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, other systems will also
fail, including driving safety systems. Observe
the information relating to the !warning
lamp (
Ypage 195).
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.
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.
The yellow !warning lamp in the instrument
cluster lights up when the ignition is switched
on. The lamp goes out when the engine starts
running.
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.
ASR (acceleration skid control)
General notes
Important safety notes
Observe the important safety guidelines for the
driving safety system (Ypage 52).
ASR can neither reduce the risk of an accident
nor suspend the laws of physics if the driver
does not pay attention when pulling away or
accelerating. ASR is only an aid. Always adapt
your driving style to suit the prevailing road and
weather conditions.
If you activate or deactivate the all-wheel drive
in a vehicle with this option, ASR will be deacti- vated for the duration of the activation/deacti-
vation process.
Vehicles without steering wheel buttons: if ASR
is malfunctioning, the :indicator lamp lights
up while the engine is running and the engine
power may be reduced (
Ypage 195).
ASR significantly improves traction, i.e. the
transmission of power from the tires to the road surface, and thus increases the vehicle's driving
stability. If the driving wheels start to spin, ASR
brakes individual drive wheels and limits the
engine torque. ASR thus significantly assists you
when pulling away and accelerating, especially
on wet or slippery roads.
If traction on the road surface is not sufficient,
even ASR 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 crucial role.
If ASR intervenes, the dwarning lamp in the
instrument cluster flashes.
Activating/deactivating ASR
GWARNING
If deactivated, ASR will not attempt to stabi-
lize the vehicle during pulling away and accel- eration. There is an increased risk of skidding
and of an accident.
Only deactivate ASR in the situations descri-
bed in the following.
!If you deactivate ASR, ESP®will still inter-
vene to stabilize the vehicle. Frequent braking
automatically triggered by ESP
®can damage
the brake system.
Driving safety systems53
Safety
Z
For this reason, deactivate ASR only briefly
and when absolutely necessary.
When ESP®is intervening and thedwarning
lamp in the instrument cluster is flashing, leave
ASR on. In this case, only depress the acceler-
ator pedal as far as required when pulling away.
XPress the àbutton.
If ASR is deactivated, the dwarning lamp
in the instrument cluster lights up.
ASR is automatically activated when the engine
is started.
It may be best to deactivate ASR briefly in the
following situations:
Rwhen using snow chains
Rin deep snow
Ron sand or gravel
If you deactivate ASR:
Rengine torque is not limited and the drive
wheels are able to spin. The spinning wheels
will then achieve a cutting effect for better
traction.
Rtraction control remains active through brake
intervention. If a drive wheel attains its tire
traction limit because one side of the road is
slippery, for example, that wheel is braked.
The traction is then increased in this situation.
Ractive brake intervention by ESP®to increase
driving stability remains active. The d
warning lamp in the instrument cluster
flashes when ESP
®is intervening.
BAS (Brake Assist System)
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.
Vehicles without steering wheel buttons: if the
BAS driving safety system is malfunctioning,
the : warning lamp lights up while the
engine is running (
Ypage 195).
BAS operates in emergency braking situations.
If you depress the brake quickly, BAS automat-
ically increases the brake pressure, thereby
reducing the stopping distance.
The brakes will function as usual once you
release the brake pedal. BAS is deactivated.
EBD (electronic brake force distribu-
tion)
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.
EBD monitors and controls the brake pressure
to the rear wheels. This enables EBD to improve
handling during braking.
Observe the information on warning and indica-
tor lamps (
Ypage 195).
ESP®(Electronic Stability Program)
Important safety notes
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,
54Driving safety systems
Safety
On vehicles with a battery main switch, you must
first switch on the power supply (Ypage 118).
iTo unlock the steering, move the steering
wheel slightly while turning the key to position

Preparing for a journey
Visual check of the vehicle exterior
XIn particular, check the following components
on the vehicle, and on the trailer as necessary:
Rlicense plates, vehicle lighting, turn signals,
brake lamps and wiper blades for dirt and
damage
Rtires and wheels for firm seating, correct
tire pressure and general condition
Rtrailer tow hitch for play and security
The trailer coupling is one of the most
important vehicle parts with regard to road
safety. The separate instructions issued by
the manufacturer pertaining to operation,
care and maintenance should be observed.
Rthat contour markings on attachments and
bodies are in good condition
XRectify any noticeable defects before com-
mencing the journey.
Checks in the vehicle
Emergency equipment and first-aid kit
XCheck the equipment to make sure that it is
accessible, complete and ready for use.
The first aid and breakdown assistance equip-
ment is in the front door stowage compartments
and behind the driver's seat.
Vehicle lighting
XTurn the key to position 2in the ignition lock.
XCheck the lighting system with the aid of a
second person.
XReplace defective bulbs (Ypage 86).
Before driving off
GWARNING
Objects in the driver's footwell may restrict
the clearance around the pedals or block a
depressed pedal. This jeopardizes the oper-
ating and road safety of the vehicle. There is a risk of an accident.
Stow all objects securely in the vehicle so that
they do not get into the driver's footwell.
When using floormats or carpets, make sure
that they are properly secured so that they do not slip or obstruct the pedals. Do not place
several floormats or carpets on top of one
another.
GWARNING
Unsuitable footwear can hinder correct usage of the pedals, e.g.:
Rshoes with thick soles
Rshoes with high heels
Rslippers
There is a risk of an accident.
Wear suitable footwear to ensure correct
usage of the pedals.
XSecure the load as per the loading guidelines
(Ypage 212).
XStow luggage items securely. Secure the load
as per the loading guidelines (Ypage 212).
XMake sure that the floormats and carpets are
properly secured so that they cannot slip and
obstruct the pedals.
XClose all doors.
Starting the engine
GWARNING
Combustion engines emit poisonous exhaust
gases such as carbon monoxide. Inhaling
these exhaust gases leads to poisoning. There
is a risk of fatal injury. Therefore never leave
the engine running in enclosed spaces with-
out sufficient ventilation.
!Do not depress the accelerator pedal when
starting the engine.
XBefore starting the engine, make sure that:
