Occupant safety
Introduction to the restraint system
The restraint system can reduce the risk of
vehicle occupants coming into contact with
parts of the vehicle's interior in the event of
an accident. The restraint system can also
reduce the forces to which vehicle occupants
are subjected during an accident.
The restraint system comprises:
RSeat belt system
RAir bags
RChild restraint system
RChild seat securing systems
The components of the restraint system work in conjunction with each other. They can only
deploy their protective function if, at all times,
all vehicle occupants:
Rhave fastened their seat belts correctly
(
Ypage 44)
Rhave adjusted their seat and head restraint
properly (
Ypage 89).
As the driver, you also have to make sure that
the steering wheel is adjusted correctly.
Observe the information relating to the cor-
rect driver's seat position (
Ypage 88).
You also have to make sure that an air bag can inflate properly if deployed (
Ypage 46).
An air bag supplements a correctly worn seat
belt. As an additional safety device, the air
bag increases the level of protection for vehi-
cle occupants in the event of an accident. For
example, if, in the event of an accident, the
protection offered by the seat belt is suffi-
cient, the air bags are not deployed. When an
accident occurs, only the air bags that
increase protection in that particular accident situation are deployed. However, seat belts
and air bags generally do not protect against
objects penetrating the vehicle from the out-
side.
Information on restraint system operation
can be found under "Triggering of the Emer-
gency Tensioning Devices and air bags"
(
Ypage 54).

fastened or a front door is opened again, the
7seat belt warning lamp goes out.
If the driver's seat belt is not fastened after
the drive system is started, an additional
warning tone will sound. The warning tone
switches off after six seconds or once the
driver's seat belt is fastened.
If the vehicle's speed exceeds 15 mph
(25 km/h) once and the driver's and front-
passenger seat belts are not fastened, a
warning tone sounds. A warning tone also
sounds with increasing intensity for
60 seconds or until the driver or front
passenger have fastened their seat belts.
If the driver or front passenger unfasten their
seat belts during the journey, the seat belt
warning is activated again.
iFor more information on the 7seat
belt warning lamp, see "Warning and indi-
cator lamps in the instrument cluster, seat
belts" (
Ypage 229).
Air bags
Introduction
The installation point of an air bag can be rec-
ognized by the AIR BAG symbol.
An air bag complements the correctly fas-
tened seat belt. It is no substitute for the seat
belt. The air bag provides additional protec-
tion in applicable accident situations.
Not all air bags are deployed in an accident.
The different air bag systems function inde-
pendently from one another (
Ypage 54).
However, no system available today can com-
pletely eliminate injuries and fatalities.
It is also not possible to rule out a risk of injury
caused by an air bag due to the high speed at
which the air bag must be deployed.
Important safety notes
GWARNING
If you do not sit in the correct seat position,
the air bag cannot protect as intended and
could even cause additional injury when
deployed. This poses an increased risk of
injury or even fatal injury.
To avoid hazardous situations, always make
sure that all of the vehicle's occupants:
Rhave fastened their seat belts correctly,
including pregnant women
Rare sitting correctly and maintain the great-
est possible distance to the air bags
Rfollow the following instructions
Always make sure that there are no objects
between the air bag and the vehicle's occu-
pants.
RAdjust the seats properly before beginning
your journey. Always make sure that the
seat is in an almost upright position. The
center of the head restraint must support
the head at about eye level.
RMove the driver's and front-passenger
seats as far back as possible. The driver's
seat position must allow the vehicle to be
driven safely.
ROnly hold the steering wheel on the out-
side. This allows the air bag to be fully
deployed.
RAlways lean against the backrest while driv-
ing. Do not lean forwards or lean against
the door or side window. You may other-
wise be in the deployment area of the air
bags.
RAlways keep your feet in the footwell in
front of the seat. Do not put your feet on the
dashboard, for example. Your feet may oth- erwise be in the deployment area of the air
bag.
RFor this reason, always secure persons less
than 5 ft (1.50 m) tall in suitable restraint
systems. Up to this height, the seat belt
cannot be worn correctly.
46Occupant safety
Safety

If a child is traveling in your vehicle, also
observe the following notes:
RAlways secure children under twelve years
of age and less than 5 ft(1.50m) tall in
suitable child restraint systems.
RChild restraint systems should be installed
on the rear seats.
ROnly secure a child in a rearward-facing
child restraint system on the front-
passenger seat when the front-passenger
front air bag is deactivated. If the
PASSENGER AIR BAG OFF indicator lamp is
permanently lit, the front-passenger front
air bag is deactivated (
Ypage 41).
RAlways observe the instructions and safety notes on the "Occupant Classification Sys-
tem (OCS)" (
Ypage 49) and on "Children
in the vehicle" (
Ypage 56) in addition to
the child restraint system manufacturer's
installation instructions.
Objects in the vehicle interior may pre-
vent an air bag from functioning correctly.
Before starting your journey and to avoid risks resulting from the speed of the air bag as it
deploys, make sure that:
Rthere are no people, animals or objects
between the vehicle occupants and an air
bag.
Rthere are no objects between the seat, door
and B-pillar.
Rno hard objects, e.g. co at hangers, hang on
the grab handles or coat hooks.
Rno accessories, such as cup holders, are
attached to the vehicle within the deploy-
ment area of an air bag, e.g. to doors, side
windows, rear side trim or side walls.
Rno heavy, sharp-edged or fragile objects
are in the pockets of your clothing. Store
such objects in a suitable place.
GWARNING
If you modify the air bag cover or affix objects
such as stickers to it, the air bag can no longer
function correctly. There is an increased risk
of injury.
Never modify an air bag cover or affix objects
to it.
GWARNING
Sensors to control the air bags are located in
the doors. Modifications or work not per-
formed correctly to the doors or door panel-
ing, as well as damaged doors, can lead to the
function of the sensors being impaired. The air
bags might therefore not function properly
anymore. Consequently, the air bags cannot
protect vehicle occupants as they are
designed to do. There is an increased risk of
injury.
Never modify the doors or parts of the doors.
Always have work on the doors or door pan-
eling carried out at a qualified specialist work-
shop.
Front air bags
Driver's air bag :deploys in front of the
steering wheel. Front-passenger front air
bag ;deploys in front of and above the glove
box.
When deployed, the front air bags offer addi-
tional head and thorax protection for the
occupants in the front seats.
The PASSENGER AIR BAG OFF and
PASSENGER AIR BAG ON indicator lamps
inform you about the status of the front-
passenger air bag (
Ypage 41).

ABS (Anti-lock Braking System)
Gene ral information
AB S regulates brake pressure in suchaway
that th e wheels do not lock when you brake.
This allows you to continue steering the vehi-
cle when braking.
The ! ABS warning lamp in the instrument
cluster lights up when the ignition is switched
on. It goes out when the engine is running.
AB S works from a speed of about 5 mph
(8 km/h), regardless of road-surface condi-
tions. ABS works on slippery surfaces, even
when you only brake gently.
Important safety notes
iObserve the "Important safety notes" sec-
tion (
Ypage 62).
GWARNING
If AB S 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.
When ABS is malfunctioning, other systems,
including driving safety systems, will also
become inoperative. Observe the information
on the ABS warning lamp (
Ypage 232) and
display messages which may be shown in the
instrument cluster(
Ypage 201).
Braking
XIf ABS intervenes: continue to depress the
brake pedal vigorously until the braking sit-
uation is over.
XTo make a fu ll brake application:
depress the brake pedal with full force.
If ABS intervenes when braking, you will fee la
pulsing in the brake pedal. The pulsating brake pedal can be an indica-
tion of hazardous road conditions, and func-
tion
s as a reminder to take extra care while
driving.
BAS (Brake Assist System)
Gene ral information
BA S operates in emergency braking situa-
tion s. If you depress the brake pedal quickly,
BA S automatically boosts the braking force,
thus shortening the stopping distance.
Important safety notes
iObserve the "Important safety notes"sec-
tion (
Ypage 62).
GWARNING
If BA S is malfunctioning, the braking distance
in an emergency braking situation is
increased. There is a risk of an accident.
In an emergenc y braking situation, depress
th e brake pedal with full force. ABSprevents
th e wheels from locking.
Braking
XKeep the brake pedal firmly depressed until
th eemergenc y braking situation is over.
AB Sprevents th e 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 information
EBD monitors and controls the brake pres-
sure on the rear wheels to improve driving
stability while braking.
Important safety notes
iObserve the "Important safety notes" sec-
tion (
Ypage 62).
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.
Observe information regarding indicator and
warning lamps (
Ypage 232) as well as dis-
play messages (
Ypage 205).
ADAPTIVE BRAKE
ADAPTIVE BRAKE enhances braking safety
and offers increased braking comfort. In addi- tion to the braking function, ADAPTIVE BRAKE
also has the HOLD function (
Ypage 163) and
hill start assist (
Ypage 134).
STEER CONTROL
General information
STEER CONTROL helps you by transmitting a
noticeable steering force to the steering
wheel in the direction required for vehicle
stabilization. This steering assistance is provided in partic-
ular if:
Rboth right wheels or both left wheels are on
a wet or slippery road surface when you
brake.
Rthe vehicle starts to skid.
Important safety notes
iObserve the "Important safety notes" sec-
tion (
Ypage 62).
No steering assistance is provided from
STEER CONTROL, if:
RESP®is malfunctioning.
Rthe lighting is faulty.
If ESP
®is malfunctioning, you will be assisted
further by the electrical power steering.
Recuperative Brake System
GWARNING
In the event of malfunctions in the Recupera-
tive Brake System, the following may occur:
Rthe braking performance of the electric
motor may be either reduced or not effec-
tive
Rbrake pedal resistance may be lower than
usual
Rpedal travel may be longer than usual
If you do not make an additional effort to apply
the brake yourself, the braking effect may not be sufficient. There is a risk of an accident.
In the event of this malfunction, continue to
depress the brake pedal. The brake system is
still fully functional.
Observe the important safety notes on driving
safety systems (
Ypage 62).
The Recuperative Brake System converts the
kinetic energy when braking into electrical
energy. The electric motor is used as an alter-
nator during braking. This electrical energy is
then stored in the high-voltage battery.
68Driving safety systems
Safety

You can find information about manually
adjustable recuperation under "Steering
wheel paddle shifters" (
Ypage 138).
If the warning light in the instrument cluster is lit up, there is a motor malfunction or a brake
malfunction.
Observe information regarding indicator and
warning lamps (
Ypage 231) as well as dis-
play messages (
Ypage 201).
