GWARNING
If the restraint system is malfunctioning,
restraint system components may be trig-
gered unintentionally or may not deploy as
intended during an accident. This can affect
for example the Emergency Tensioning
Device or the air bag. This poses an increased
risk of injury or even fatal injury.
Have the restraint system checked and
repaired in a qualified specialist workshop as
soon as possible.
Seat belts
Introduction
Seat belts are the most effective means of
restricting the movement of vehicle occupants
in the event of an accident or the vehicle rolling
over. This reduces the risk of vehicle occupants coming into contact with parts of the vehicle
interior or being ejected from the vehicle. Fur-
thermore, the seat belt helps to keep the vehicle
occupant in the best position in relation to the
air bag.
The seat belt system comprises:
RSeat belts
REmergency Tensioning Devices for the front
seat belts
The seat belt system also includes a belt force
limiter for the relevant seat if the vehicle is
equipped with a front air bag.
On vehicles with a front-passenger bench
seat, only the seat belt of the outer front-
passenger seat has a belt force limiter.
The seat belt system does not include an Emer- gency Tensioning Device and a belt force limiter
if the vehicle does not have a driver's air bag.
If the seat belt is pulled out of the belt outlet
quickly or with a jerky movement, the belt
retractor locks. The belt strap cannot be extrac-
ted any further. The Emergency Tensioning Device tightens the
seat belt in an accident, pulling the belt close
against the body. However it does not pull the
vehicle
occup
ant back in the direction of the
backrest.
The Emergency Tensioning Device does not cor-
rect an incorrect seat position or the routing of
an incorrectly fastened seat belt.
When triggered, a belt force limiter helps to
reduce the force exerted by the seat belt on the
vehicle occupant.
The belt force limiters are synchronized with the
front air bags which absorb part of the deceler-
ation force. This can reduce the force exerted on
the vehicle occupants during an accident.
The Emergency Tensioning Device of the front-
passenger seat is triggered independently of the
lock status of the seat belt.
Important safety notes
The use of seat belts and child restraint systems
is required by law in:
Rall 50 states
Rthe U.S. territories
Rthe District of Columbia
Rall Canadian provinces
Even where this is not required by law, all vehicle
occupants should correctly fasten their seat
belts before starting the journey.
GWARNING
If the seat belt is not worn correctly, it cannot
perform its intended protective function. An
incorrectly fastened seat belt can also cause
injuries, for example, in the event of an acci-
dent or when braking or changing direction
abruptly. This poses an increased risk of injury
or even fatal injury.
Always ensure that all vehicle occupants have
their seat belts fastened correctly and are sit-
ting properly.
GWARNING
The seat belt does not offer the intended level of protection if you have not moved the back-
rest to an almost vertical position. When brak-
ing or in the event of an accident, you could
slide underneath the seat belt and sustain
abdomen or neck injuries, for example. This

Driving safety systems
Overview
In this section, you will find information about
the following driving safety systems:
RABS ( Anti-lock Braking System)
RASR (Acceleration SkidControl)
RBAS ( Brake Assist System)
REBD ( Electronic Brake Force Distribution)
RESP®(E lectronic StabilityProgram)
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 Pay particular attention to the information
regarding tires, tire tread and winter operation
under "Wheels and tires" (
Ypage 243).
ABS (Anti-lock Braking System)
Important safety notes
Observe the important safety guidelines for the
driving safety system (Ypage 53).
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 191).
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.

in an emergenc ybraking situation is
increased. There is aris kof an accident.
54Driving safety systems
Safety

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 191).
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 191).
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, please consult a qualified specialist workshop
in advance. You could otherwise damage the
drive train or the brake system.
If you activate or deactivate the all-wheel drive
in a vehicle with this option, ESP
®will be deac-
tivated for the duration of the activation/deac-
tivation process.
If ESP
®is malfunctioning, the hindicator
lamp lights up while the engine is running and
the engine power may be reduced
(
Ypage 190).
iOnly use wheels with the recommended tire
sizes. Only then will ESP®function properly.
4ETS (Electronic Traction 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.
4ETS is only active when all-wheel drive is acti-
vated (
Ypage 145).
4ETS ensures permanent drive for all four
wheels, and together with ESP
®it improves the
vehicle's traction.
If a driven wheel spins due to lack of traction:
RWhen pulling away, make use of the traction
control integrated in ESP®. Depress the
accelerator pedal as far as necessary.
RWhile driving, slowly take your foot off the
accelerator pedal.
In wintry driving conditions, always use winter
tires (M+S tires) and if necessary, snow chains
(
Ypage 246). This is the only way to get the full
benefit from the all-wheel drive system.
Crosswind Assist
