· Important things to do before driving
Safety is everybody 's job! Vehicle and occupant
safety always depends on the informed and care­
ful driver .
For your safety and the safety of your passen­
gers,
before driving always:
.. Make sure that a ll lights and signals are operat­
ing correctly .
.. Make sure tha t the tire pressure is correct .
.. Make sure that all windows are clean and afford
good vis ibility to the outs ide .
.,. Sec ure all luggage and othe r items ca refully
¢ page 259 .
.,. Mak e sure tha t noth ing ca n interfere with the
pedals .
.. Adjust front seat, head restraint and mirrors
correctly for your height.
.. Applies to: adjustable head restraints: Instruct
passengers to adjust the head restraints ac­
cording to the ir height .
.. Make sure to use the rig ht child restraint cor­
rectly to protect
chi ldren ~ page 295 , Child
safety.
.,. Si t properly in yo ur seat a nd make su re t hat
your passengers do the same ¢
page 65, Front
seats.
.. Fasten your safety belt and wear it properly . Al­
so instruct your passenge rs to fasten thei r sa fe­
ty belts properly ¢
page 263.
What impairs driving safety?
Safe driving is directly related to the condition of
the vehicle , the driver as well as the driver's abili ­
ty to concentra te on the road withou t being dis­
tracted.
The driver is responsib le for the sa fety of the ve­
hicle and a ll of its occupants . If your ability to
drive is impa ired, safety risks for everybody in the
vehicle increase and you a lso become a hazard to
everyone else on the road ¢
,&.. There fore:
.. Do not let yourse lf be distracted by passengers
or by using a cellular telephone .
.. NEVER dr ive whe n your driving ab ility is im -
paired (by med ications, alcohol, drugs, e tc.) .
..,.

Driving safety
-Always sit in an upright position and never
lean against or place any part of your body
too close to the area where the airbags are located .
- Before driving, always adjust the front seats
and head restraints properly and make sure
that all passengers are properly restrained .
- Never adjust the seats while the vehicle is
moving . Your seat may move unexpectedly
and you could lose control of the vehicle.
- Never drive with the backrest reclined or
tilted far back! The farther the backrests are
tilted back, the greater the risk of injury due
to incorrect positioning of the safety belt and improper seating position .
- Children must always ride in child safety
seats
c::> page 295 . Special precautions ap­
ply when installing a child safety seat on the
front passenger seat
c::> page 2 71 .
Proper seating position for the f ront
passenger
The proper front passenger seating position is
important for safe, relaxed driving.
For your own safety and to reduce the risk of in­
jury in the event of an accident, we recommend
that you adjust the seat for the front passenger
to the following position:
.. Adjust the angle of the seatback so that it is in
an upright position and your back comes in full
contact with it whenever the vehicle is moving.
.. Applies to: adjustable head restraints: Adjust
the head restraint so the upper edge is as even
a s possible with the top of your head . If that is
not possible, try to adjust the head restraint so
that it is as close to this position as possible
c::> page 66 .
.. Keep both feet flat on the floor in front of the
front passenger seat.
.. Fasten and wear safety belts correct­
ly <=:> page 266.

A WARNING , _
Front seat passengers who are unbelted, out
of position or too close to the airbag can be
seriously injured or killed by the airbag as it
unfolds. To help reduce the risk of serious
personal injury:
- Passengers must always sit in an upright po­
sition and never lean aga inst or place any
part of their body too close to the area
where the airbags are located.
- Passengers who are unbelted, out of posi­
tion or too close to the airbag can be seri­
ously injured by an airbag as it unfolds with
great force in the blink of an eye.
- Always make sure that there are at least
10 inches (25 cm) between the front pas­
senger's breastbone and the instrument
panel.
- Always make sure that there are at least 4 inches (10 cm) between the front passen­
ger's knees and the lower part of the instru­
ment panel.
- Each passenger must always sit on a seat of
their own and properly fasten and wear the
safety belt belonging to that seat.
- Before driving, always adjust the front pas­
senger seat and head restraint properly.
- Always keep your feet on the floor in front
of the seat. Never rest them on the seat, in­
strument panel, out of the window, etc . The
airbag system and safety belt will not be
able to protect you properly and can even in ­
crease the risk of injury in a crash .
- Never drive with the backrest reclined or
tilted far back! The farther the backrests are
tilted back, the greater the r isk of injury due
to incorrect positioning of the safety be lt
and improper seat ing position.
- Ch ildren must always ride in child safety
seats
