Driving safety
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 w indows are clean and afford
good vis ibility to the outs ide.

c::> page 63, c::> page 63 .
.. Make sure that nothing can interfere with the
peda ls .
.. Adjust front seat, head restraint and mirrors
correct ly for your height.
.. Instruct passengers to adjust the head re­
straints according to their height.
.. Make sure to use the right child restraint cor­
rectly to protect children
c::> page 294, Child

.. Fasten your safety belt and wear it properly. Al­
so instruct your passengers to fasten their safe­
ty belts properly
c::> page 260.
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 concentrate on the road without being dis­
tracted.
The driver is responsible for the safety 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
c::> &_ . Therefore:
.. Do not let yourse lf be distracted by passengers
or by using a cellular telephone .
.. NEVER drive when your driving abi lity is im­
pa ired (by med ications, alcohol, drugs, etc .) .
.. Observe all traffic laws, rules of the road and
speed lim its and plain common sense .

-Pointing the steering wheel toward your
face decreases the ability of the supplemen­
tal driver's airbag to protect you in a colli­ sion.
- 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
properly and make sure that all passengers
are properly restrained.
- For adjustable head restraints : before driv­
ing, always also adjust the head restraints
properly.
- 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 seats
~ page 294. Special precautions apply
when installing a child seat on the front
passenger seat
i::> page 269 .
Proper seating position for the front
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.
.. For adjustable head restraints: adjust the head
restraint so the upper edge is as even as possi­
ble with the top of your head. If that is not pos­
sible, try to adjust the head restraint so that it
is as close to this position as possible
~ page 61. Move the head restraint so that it is
as close to the back of the head as possible.
Driving safety
.. Keep both feet flat on the floor in front of the
front passenger seat.
.. Fasten and wear safety belts correctly

front passenger's seat, see

personal injury:
- Passengers must always sit in an upright po­
sition and never lean against or place any part of their body too close to the area
where the airbags are located.

Examples of improper seating positions
The occupant restraint system con only reduce
the risk of injury if vehicle occupants ore properly
seated.
I mp roper seating posi tions can cause se rious in ­
ju ry o r death. Safety bel ts can only work when
they are p roperly positioned on the body. Im ­
proper seating positions reduce the effectiveness
of safety belts and w ill even increase the r is k of
in ju ry and death by moving the safety belt to crit­
ical areas of t he body. Improper seating posit ions
also increase the risk of ser ious injury and death
when an airbag deploys a nd strikes an occupant
who is not i n the prope r seat ing pos ition . A d rive r

gage compartment and close the rear lid be­
coming trapped and unable to get out . Be­
ing t rapped in a veh icle can lead to se rious
persona l injury.
- Never let children play in or around the veh i­

p ressure labe l. Th e tire pressu re labe l is lo ­
ca ted on t he driver 's s ide B-p illar. The tir e
p ressure labe l lists the recommended cold
tire inflation pressures for the vehicle at its max imum capacity weig ht and the t ires t hat

In a col lision, the laws of p hysics mean that even
sma ller items that are loose in the vehicle will
become heavy missiles that can cause ser ious in­
jury. Items in t he ve hicle possess energy which
vary with vehicle speed and the weight of the item . Veh icle speed is the most s ignificant factor .
For examp le, in a frontal collision at a speed of
30 mph (48 km/h), the forces act ing o n a 10-lb
256

weight of the item . This means that the weight
of the item would s udden ly be about
200 lbs. (90 kg). You can imag ine the in juries
that a 200 lbs. (90 kg) item flying freely through
the passenger compartment could cause in a col­
l is ion like t his.
