• T he shoulder belt part shou ld route approximate ly over the
middle of your shoulder -under no circumstances shou ld it route over
you r neck a nd throat area~ & in "Safety belt position" on
page 140 .
• With the front seats, the height adjustment of the seat can also
be used to adjust the position of the safety belts. •
Improperly worn safety belts
Incorrectly positioned safety belts can cause severe inju
nes.
Wearing safety belts improperly can cause serious injury or
death . Safety belts can only work when they are correctly
positioned on the body . Improper seating positions reduce
the effectiveness of safety belts and will even increase the
ris k of injury and death by moving the safety belt to critical
areas of the body . Improper seating positions also increase
the risk of serious injury and death when an airbag deploys
and str ikes an occupant who is not in the correct seating posi
tion. A driver is responsible for the safety of all vehicle occu pants and especially for chi ldren. T herefore:
- Never permit anyone to assume an incorrect sitting posi-
tion in the vehicle while traveling
~ & .
The fo llowing lists on ly some examples of imprope rly worn safety
belts th at will increase the risk of ser ious injury and death . O ur hope
is that these examples w ill make you more aware of seat ing pos itions
t ha t are dangero us.
Therefore, whenever the vehicle is moving :
• never wear the sho ulder belt unde r yo ur arm
• neve r let the shoulder be lt pass ove r you r neck
• neve r wear the safety belt loosely

Safety belt pretensioners
How safety belt pretensioners work
In front, side and rear end collisions above a particular
severity, safety belts are tensioned automatically .
The safety belts are eq uipped with safety belt p retensioners. The
system is activated by sensors in fron t, side and rear-end collisions of
great sever ity. Thi s tightens t he be lt and takes up belt slack~ & in
"Service and disposal of sa fety belt p retens ioner". Tak ing up the slack
helps to reduce forward occupan t movement during a collis ion .

Advanced Airbag System components
Th e fron t passenger sea t in your veh icle ha s a lot of very im port ant
parts of the Advanced A irbag System in it . These parts include the
we ight- sens ing mat, sensors, wiring, bracke ts, and more. The func

The front Advanced Airbag System consists of the
following:
• Cras h sensors in the front of t he veh icle that measure vehicle
a cc ele ra tion/de ce le ra tion to prov ide i nform ation to the Adv ance d
Airbag System about the severi ty of the crash .
• An e lec tron ic contro l uni t, w ith integr ate d cr ash sensor s fo r fron t

Side airbags
Description of side airbags
The airbag system can provide supplemental protection
to properly restrained occupants .
Fig. 140 Side airbag
loc ation in the driver's
seat
The side airbags are located in the sides of the front seat backrests
=> fig. 140 and the rear backrest* facing the doors. They are identi
fied by the word "AIRBAG".
The side airbag system basically consists of:
• the electronic control module and externa l side impact sensors
• the two side airbags located in the sides of the front backrests
Safety first Vehicle OP-eration
Airbag system
• two rear side airbags (as an ordered option)
• the airbag warning light in the instrument clus ter.
The airbag system is monitored electronically to make certain that it
is funct ion ing properly at all times. Each time you turn on the igni
tion, the airbag system indicator light w ill come on for a few seconds
(self diagnostics).
Th e side airbag system supplements the safety belts and can help to
reduce the risk of injury to the dr iver's, front and rear* passenger's
upper torso and head on the sid e of the vehicle that is struck in a side
collision . The airbag deploys only in side impacts and only when the
vehicle accelerat ion registered by the contro l unit is high enoug h. If
this rate is below the reference value programmed into the contro l
unit , the side airbags will not be triggered, even though the car may
be badly damaged as a result of the collision . It is not possible to
def ine an a irbag triggering range that will cover every possible angle
of impact, since the circu mstances will vary considerably between
one collision and another. Important factors include, for example,
the nature (hard or soft) of the impacting object, the angle of impact,
vehicle speed, etc.=>
page 163, "Important safety instructions on
the sid e airbag system".
Aside from their normal safety function, safety belts work to help keep the driver or front passenger in position in the event of a side
collision so that the side airbags can prov ide p rotection.
The airbag system is
not a substitute for your safety belt. Rather, it is
part of the overall occupant restraint system in your veh icle. Always
remember that the side airbag system can only help to protect you if
you are wearing yo ur safety belt and wearing i t properly. This is
another reason why you shou ld always wear your safety belts, not just
because the law requires yo u to do so=>
page 135, "Genera l notes" .
It is important to remember that while the supp lemental side airbag
system is designed to reduce the likelihood of serious injuries, other
injur ies, for example, swelling, bruising, and minor abrasions can
also be assoc iated with deployed side airbags. Remember too, side
airbags will dep loy only once and only in certain kinds of accidents -
your safety belts are always there to offer protection.
