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 adjusting the front
seats to provide safe and comfortable support
for the driver and the front passenger. Adjust
you r seat prope rly so that :
- you can easily and quickly reach all the
switches and controls in the instrument
panel
-your body is properly supported thus reduc­
ing physical stress and fatigue
- the safety be lts and airbag system can offer
maximum protection ¢
page 144.
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
passenger's seat. Always follow the informa­
tion regarding child safety provided in
¢ page 165, Child Safety.
WARNING
Refer to¢ page 126, Driving Safely for
important information, tips, suggestions
and warnings that you should read and fol­
low for your own safety and the safety of
your passengers.
A WARNING
, -
Incorrect seating position of the driver and
all other passengers can result in serious
personal injury .
- Always keep your feet on the floor when
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 applies 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 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 them­
selves and the steering wheel and/or in­
strument panel.
If you're sitting any
closer than this, the airbag system can­
not protect you properly. In addition, the
front seats and head restraints must be
adjusted to your body height so that they
can give you maximum protection.
- Always try to keep as much distance as
possible between yourself and the steer­
ing wheel or instrument panel.
- Do not adjust the driver's or front pas­
senger 's seat while the vehicle is moving.
Your seat may move unexpectedly, caus­
ing sudden loss of veh icle control and
personal injury. If you adjust your seat
while the veh icle is moving, you are out
of posit ion.
Driver's seat
The correct seat position is important for safe
and relaxed driving .
We recommend that you adjust the driver's
seat in the following manner :
.. Adjust the seat in fore and aft direction so
that you can easily push the pedals to the
floor wh ile keeping your knees slightly bent
o &. in Why is your seat adjustment so im ­
portant? on page
60 .
.,. Adjust the seatback so that when you sit
w ith your back against the seatback , you can
still grasp the top of the steering wheel.
.. Applies to vehicles with adjustable head re­
straints: Adjust the head restraint so the up­
per 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 .,.

A WARNING
Never place any objects in the driver's foot­
well. An object could get into the pedal
area and interfere with pedal function. In
case of sudden braking or an accident, you
would not be able to brake or accelerate .
Front passenger's seat
Always move the front passenger seat into
the rearmost position .
To avoid contact with the airbag while it is de­
ploying, do not sit any closer to the instru­
ment panel than necessary and always wear
the three-point safety belt provided adjusted
correctly . We recommend that you adjust the
passenger's seat in the following manner:
.,. Bring the backrest up to an (almost) upright
position.
Do not ride with the seat reclined .
