General information
Why is your seat adjustment so important?
The safety belts and the airbag system can only
provide maximum protection if the front seats are correctly adjusted.
There are various ways of adjusting the front
seats to provide safe and comfortable support
for the driver and the front passenger. Adjust
your seat properly so that:
- you can easily and quickly reach all the switches
and controls in the instrument panel
- your body is properly supported thus reducing
physical stress and fatigue
- the safety belts and a irbag system can offer
maximum protection
¢ page 132.
In the following sections, you will see exactly
how you can best adjust your seats.
There are special regulations and instructions for installing a child safety seat on the front pas­
senger's seat. Always follow the information re­
garding child safety provided in¢
page 152,
Child safety.
A WARNING -
Refer to¢ page 113, Driving safety for im­
portant information, t ips, suggestions and
warnings that you should read and follow for
your own safety and the safety of your pas­ senge rs.
A WARNING
Incorrect seating position of the dr iver and all
other passengers can resu lt in serious person­
al injury.
- Always keep your feet on the floor when the
vehicle is in motion -never put your feet on
top of the instrument pane l, out of the win­
dow or on top of the seat cushion. This ap­
plies especially to the passengers . If your
seating pos it ion is incorrect, you increase
the risk of injury in the case of sudden brak­
ing or an accident. If the airbag inflates and
Seat s and stor age
the seating position is incorrect, this cou ld
result in personal injury or even death.
- It is important for both the driver and front
passenger to keep a distance of at least
10 inches (25 cm) between themselves and
the steering wheel and/or instrument panel.
If you're sitting any closer than this, the air­
bag system cannot protect you properly. In
addition, the front seats and head restraints must be adjusted to your body height so
that they can give you max imum protect ion.
- Always try to keep as much distance as pos­
sible between yourself and the steer ing
wheel or instrument pane l.
- Do not adjust the driver's o r front passeng­
er 's seat while the veh icle is moving. Your
seat may move unexpectedly, causing sud­
den loss of vehicle control and persona l in­
jury.
If you adjust your seat whi le the vehicle
is moving, you are out of position.
Driver's seat
The correct seat position is important for safe
and relaxed driving.
We recommend that you adjust the dr iver's seat
in the following manner:
"' Adjust the seat in fore and aft direction so that
you can eas ily push the pedals to the floor
while keeping your knees slightly bent¢.&,
in
Why is your seat adjustment so important? on

your back against the seatback, you can still
grasp the top of the steering wheel.
"' App lies to veh icles w ith adjustable head re­
straints: Adjust the head restraint so the upper
edge is as even as possible with the top of your

A WARNING
Drivers who are unbelted, out of position or
too close to the airbag can be seriously in­
jured by an airbag as it unfolds. To help re­
duce the risk of serious personal injury:
- Always adjust the driver's seat and the
steering wheel so that there are at least
10 inches (25 cm) between your breastbone
and the steering wheel.
- Always hold the steering wheel on the out­
side of the steering wheel rim with your
hands at the 9 o'clock and 3 o'clock posi­
tions to help reduce the risk of personal in­
jury if the driver's airbag inflates.
- Never hold the steering wheel at the
12 o'clock position or with your hands at
other positions inside the steering wheel
rim or on the steering wheel hub. Holding
the steering wheel the wrong way can cause
serious injuries to the hands, arms and head
if the driver's airbag deploys.
- 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
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

ply when installing a child safety seat on the
front passenger seat¢

Driving safety
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:
.,. Move the front passenger seat back as far as
possible . There must be a minimum of 10 in­
ches (25 cm) between the breastbone and the
instrument panel¢.&, .
.,. 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 vehicles with adjustable head re­
straints: Adjust the head restraint so the upper
edge is as even as 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 posi­
tion as possible .
.,. 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 ¢
page 59.
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 per­
sonal 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.
- 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 passen­
ger's breastbone and the instrument panel.

their own and properly fasten and wear the
safety belt belonging to that seat.
- Before driving, a lways 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 pane l, out of the window, etc . The
airbag system and safety belt will not be
able to protect you properly and can even in ­
c reas e the risk of injury in a crash.
- Never dr ive with the backrest recl ined or
t ilted far back! The farther the backrests are
t il te d back, the greater the r isk of injury due
to incorrect pos itioni ng of the safety bel t
and improper se ating posi tion.

Proper seating positions for passengers in
rear seats
Rear seat passengers must sit upright with both
feet on the floor consistent with their physical
size and b e properly r estrained wh enever the ve­
hicle i s in use.
To reduce the risk of injury caused by an incorrect
seating position in the event of a sudden braking maneuver or an accident, your passengers on the
rear bench seat must always observe the follow­
ing:
"' Make sure that the seatback is securely latched
in the upright pos ition
¢ page 66 .
"' Keep both feet flat in the footwell in front of
the rear seat.
"' Faste n and wear safety belts prope rly

-Each passenger must always sit on a seat o f
their own and proper ly fasten and wea r the
safety belt belong ing to that seat.
- Safety belts only offer maximum protection
when the seatback is securely latched in the

q poge 152.
Examples of improper seating positions
The occupant restraint system con only reduce
the risk of injury if vehicle occupants ore properly
seated.
Improper seating posit ions can cause serious in­
jury o r death . Safety be lts can only work when
they are prope rly positioned on the body. Im­
p roper seating posit ions reduce the effectiveness
of safety belts and wi ll even increase the risk of
in ju ry and death by moving the safety belt to cr it­
ical areas of the body. Improper seating positions
also increase the risk of serious injury and death
when an airbag deploys a nd strikes an occupant
who is not in the proper seating position . A driver
i s responsible for the safety of all vehicle occu­
pants and especia lly for children. Therefore:
.. Never allow anyone to assume an incorrect
seat ing pos it ion when the veh icle is being used
~ & -
The follow ing bulletins list only some sample po­
sitions that will increase the risk of ser ious injury
and death . Our hope is that these examples w ill
make you mor e aware of seat ing pos itions that
are dangerous.
The refore, whene ver the vehicle is moving:
- never stand up in the vehicle
- never stand on the seats
Dr ivin g s afet y
-neve r kneel on the seats
- neve r ride w it h the seatback reclined
- never lie down on the rear seat
- never lean up against the instrument panel
- never s it on the edge of the seat
- never s it sideways
- never lean out the window
- never put your feet out the window
- neve r put your feet on the instr ument pane l
- neve r rest your feet on the seat cush ion or back
of the seat
- never ride in the footwell
- never ride in the cargo area
A WARNING
Imp roper seating posit ions increase the risk
of ser ious personal in ju ry and death whenever
