Correct use of theseat belts
GWARNING
USESEATBELTS PROPERLY
RSeat beltscan only work when used
properly. Never wear seat beltsinany other
way than as describedinthissection, as
that couldresult in serious injuries in the
event of an accident.
REachoccupantshould wear their seat belt
at all times, because seat belts help reduce
the likelihood of and potential severity of
injuries in accidents, including rollovers.
The integrated restraint system includes
SRS (driver front air bag, driver's side knee
bag, front-passenger front air bag, side
impact air bags, pelvis air bags, window
curtain air bags for the side windows),
EmergencyTensioning Devices, seat belt
force limiters, and front seat knee bolsters.
The system is designed to enhance the
protection offered to properly belted
occupants in certain frontal (front air bags,
driver's side knee bag and ETDs) and side
(side impact air bags, window curtain air
bags, and ETDs) impacts which exceed
preset deployment thresholds and in
certain rollovers (window curtain air bags
and ETDs).
RNever wear the shoulder belt under your
arm, across your neck or off your shoulder.
Inafrontal crash, your body would move
too far forward. That would increase the
chance of head and neck injuries. The seat
belt would also apply too much force to the
ribs or abdomen, which could severely
injure internal organs such as your liver or
spleen.
Adjust the seat belt so that the shoulder
section is located as close as possible to
the middle of the shoulder. It should not
touch the neck.Never pass the shoulder
portion of the seat belt under your arm. For
this purpose, you can adjust the height of
the seat belt outlet.
RPosition the lap belt as low as possible on
your hips and not across the abdomen. If
the lap belt is positioned across your
abdomen, it could cause serious injuries in
acrash.
RNever wear seat belts over rigid or
breakable objects in or on your clothing,
such as eyeglasses, pens, keys etc., as
these might cause injuries.
RMake sure the seat belt is alwaysfitted
snugly. Take special care of this when
wearing loose clothing.
RNever useaseat belt for more than one
person atatime. Do not fastenaseat belt
aroundaperson and another person or
other objects at the same time.
RSeat belts should not be worn twisted. In a
crash, you would not have the full width of
the seat belt to distributeimpact forces.
The twisted seat belt against yourbody
could cause injuries.
RPregnant women should also alwaysuse a
lap-shoulder belt. The lap belt portion
should be positioned as low as possible on
the hips to avoid any possible pressure on
the abdomen.
RPlace the seat backrest inaposition that is
as upright as possible.
RCheck your seat belt during travel to make
sure it is properly positioned.
RNever place your feet on the instrument
panel, dashboard, or on the seat. Always
keep both feet on the floor in front of the
seat.
RWhen usingaseat belt to secure infant
restraints, toddler restraints, or children in
booster seats, alwaysfollow the child seat
manufacturer'sinstructions.

health hazard and does not indicate that there
isafire in the vehicle. The dust might cause
some temporary breathing difficulty for
people with asthma or other breathing
trouble. To avoid this, you may wish to get out
of the vehicle as soon as it is safe to do so.
You can also open the window to allow fresh
air to enter the vehicle interior. TheSRS
warning lamp lights up.
If the seat belt is also equipped withaseat
belt force limiter and this is triggered, the
force exerted by the seat belt on the vehicle
occupant is reduced.
The seat belt force limiters for the front seats
are synchronized with the front air bags,
which take onapart of the deceleration force.
This results in the force exerted on the
occupant being distributed overagreater
area.

Important safety notes
GWARNING
According to accident statistics, children are
safer when properly restrained in the rear
seating positions than in the front seating
position. Thus, we strongly recommendthat
children be placed in the rear seats whenever
possible. Regardless of seating position,
children 12 years old and under must be
seated and properly secured in an appropriate
infant restraint,toddler restraint,orbooster
seat recommended for the size and weight of
the child.
The infant or child restraint must be properly
secured with the vehicle's seat belt, the seat
belt and top tether strap, or lower anchors and
top tether strap, fully in accordance with the
child seat manufacturer's instructions.
Occupants, especially children, should always
sit as upright as possible, wear the seat belt
properly and use an appropriately sized infant
restraint,toddler restraint,orbooster seat
recommended for the size and weight of the
child.
Children can be killed or seriously injured by
an inflating air bag. Note the following
important information when circumstances
require you to placeachild in the front
passenger seat:
RYour vehicle is equipped with air bag
technology designed to deactivate the front
passenger front air bag in your vehicle
when the system senses the weight of a
typical 12-month-old child or less along
with the weight ofastandard appropriate
child restraint on the front passenger seat.
RFor children larger than the typical
12-month-old child, the front passenger
front air bag may or may not be activated.
Always make sure theindicator
lamp is illuminated, indicatingthat the front
passenger front air bag is deactivated.
RAchild inarear-facing child restraint on the
front passenger seat will be seriously
injured or even killed if the front passenger
front air bag inflates inacollision which
could occur under some circumstances,
even with the air bag technology installed
in your vehicle. The only means to
completely eliminate this risk is to never
placeachild inarear-facing child restraint
in the front seat. We therefore strongly
recommendthat you always placeachild
inarear-facing child restraint inabackseat.
RIf you must installarear-facing child
restraint on the front passenger seat
because circumstances require you to do
so, make sure theindicator
lamp is illuminated, indicatingthat the front
passenger front air bag is deactivated.
Should theindicator lamp not
illuminateorgoout while the restraint is
installed, please checkinstallation.
Periodically check theindicator
lamp while drivingtomake sure the
indicator lamp is illuminated. If the
indicator lamp goes out or
remainsout, do not transportachild on the

Driving safety systems
Overview of driving safety systems
In this section, you will find information about
the following driving safety systems:
RABS (Anti-lockBrakingSystem)
(Ypage 66)
RBAS (BrakeAssistSystem) (Ypage 67)
RBAS PLUS (BrakeAssistSystem Plus)
(Ypage 67)
RESP®(ElectronicStabilityProgram)
(Ypage 68)
REBD (ElectronicBrake forceDistribution)
(Ypage 71)
RADAPTIVE BRAKE (Ypage 72)
RPRE-SAFE®Brake (Ypage 72)
Important safety notes
If you fail to adapt your driving style or
become distracted, the driving safety
systems can neither 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 and for braking in
good time. Always adapt your driving style to
suit the prevailing road, weather and traffic
conditionsand maintainasafe distancefrom
thevehicle in front. Drive carefully.
iThe driving safety systems describedonly
work as effectivelyaspossible when there
is adequatecontactbetween thetires and
theroad surface. Pleasepay special
attentiontothenotesontires,
recommendedminimumtire tread depths,
etc.(Ypage 334).
In wintry drivingconditions, always use
winter tires (M+S tires) and if necessary,
snowchains. Only in this way will the
drivingsafetysystems described in this
section work as effectively as possible.
ABS (Anti-lock BrakingSystem)
Important safety notes
iObserve the "Importantsafetynotes"
section(Ypage 66).
GWARNING
If ABSisfaulty, the wheels could lock when
braking. The steerability and braking
characteristics may be severely impaired.
Additionally, further driving safety systems
are deactivated. There is an increased danger
of skidding and accidents.
Drive on carefully.Have ABS checked
immediately ataqualified 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 267) and
displaymessages which may be shown in the
instrument cluster (Ypage 238).
ABS regulates brake pressure in suchaway
that the wheels do not lock when you brake.
This allows you to continue steering the
vehicle when braking.
