General recommen­
dations
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 adjust ing 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 quick ly reach all the
switches and controls in the instrument
panel
-your body is prope rly supported thus reduc­
ing physical stress and fatigue
- the safety be lts and airbag system can offer
maximum protection ¢
page 144.
In the following sec tions, you will see exactly
how you can best adjust you r seats .
There are special regulations and instructions
for insta lling a child safety seat on the front
passenger's seat. Always follow the informa­
tion rega rd ing child safety provided in
G page 165, Child Safety.
WARNING

the vehicle is in motion -never put your
feet on top of the instrument panel, out of the w indow or on top of the seat cush­
ion. This app lies especially to the passen- gers
. If your seating position is incorrect,
you increase the risk of injury in the case of sudden braking or an accident. If the
airbag inflates and the seating position is incorrect, this could result in pe rsonal
in ju ry or even death.
- It is important for both the driver and front passenge r to keep a distance of at
least 10 inches (25 cm) between them­
selves and the steering wheel and/or in­

possible between yourself and the steer­
ing wheel or instrument panel.

General overview
.&_ WARNING
-Always remove objects from the instru­

could slide around inside the veh icle
while driv ing or when accelerat ing o r
when applying the brakes or when dr iv­
ing around a corne r .
- When you are driving make sure that
anyth ing you may have placed in the cen­
ter console or other storage locations
cannot fall out into the footwells. In case
of sudden braking you would not be able
to brake, depress the clutch or acce ler ­

- Any pieces o f clothing that you have
hung up must not i nterfere wit h the driv­
er's view . The coat hooks are designed
only for lightweight clothing. Never hang

kinetic energy which varies with the vehicle
and the weight of the item . Vehicle speed is
the most significant factor .
F or example, in a frontal coll is ion at a speed
of 30 mph ( 48 km/h), the forces acting on a
10 -lb (5 kg) object are about 20 times the
normal weight of the item. Th is means that
the weight of the item would suddenly be the
equivalent of about 200 lbs (90 kg). One can
eas ily imagine the injur ies that an item of that
weight flying freely through the passenger compartment can cause in a co llision at a
speed conside red relat ively low.
& WARNING
Weak, d amaged or improper s traps used
to secure items to t ie-downs can fail du r­
ing hard brak ing or in a coll ision and cause
serious persona l in jury .
- Always use suitab le retaining straps and
properly secure items to the tie-downs in
the luggage compartment to help pre­
vent items from shifting or flying for­
ward.
- Never attach a child seat tether strap to
a tie-down.
- For strength-related reasons, the mount­
ing hooks can only be used to secure ob­
jects weighing up to 10 lb. (5 kg). Heav i­
er objects w ill not be adequately secured
- there is a r isk of injury .

128 Driving Safely
• Always keep both feet in the footwell so
that you are in control of the vehicle at all
times.
For detailed information on how to adjust the
driver's seat, see
¢ page 56.
A WARNING
Drivers who are unbelted, out of position
or too close to the airbag can be seriously
injured by an airbag as it unfolds. To help
reduce 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 breast­
bone and the steering wheel.
- Always hold the steering wheel on the
outside of the steering wheel rim with
your hands at the 9 o'clock and 3 o'clock positions to help reduce the risk of per­
sonal injury 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. Hold­
ing the steering wheel the wrong way
can cause serious injuries to the hands,
arms and head if the driver's airbag de­
ploys.
- Pointing the steering wheel toward your
face decreases the ability of the supple­
mental driver 's airbag to protect you in a
collision .
- Always sit in an upright position and nev­
er lean against or place any part of your
body too close to the area where the air ­
bags are located.
- Before driving, always adjust the front
seats and head restraints properly and
make sure that all passengers are prop­
erly restrained.
- Never adjust the seats while the vehicle
is moving . Your seat may move unexpect­
edly and you could lose control of the ve­
hicle.
- Never drive with the backrest reclined or
tilted far back! The farther the backrests
are tilted back, the greater the risk of in- jury due to incorrect positioning of the
safety belt and improper seating posi­
tion.
- Children must always ride in child safety
seats ¢
page 165. Special precautions
apply when installing a child safety seat
on the front passenger seat¢
page 144 .
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
injury in the event of an accident, we recom ­
mend 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 inches (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
