General information
Important information
A WARNING
Refer to the chapter Driving Safely
c::> page 130, Driving safety for important in­
formation, tips, suggestions and warnings
that you should read and follow for your own
safety and the safety of your passengers.
Why is your seat adjustment so important?
The safety belts and the airbag system con only
provide maximum protection if the front seats
ore 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 airbag system can offer
maximum protection
c::> page 148.
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 seat on the front passenger's
seat . Always follow the information regarding
child safety provided in
c::> page 172, Child safe­
ty.
A WARNING
Incorrect seating position of the driver and all
other passengers can result 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 panel, out of the win­
dow or on top of the seat cushion. This ap­
plies especially to the passengers. If your
seating position is incorrect, you increase
Seats and storage
the risk of injury in the case of sudden brak­
ing 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 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 maximum protection.
- Always try to keep as much distance as pos­
sible between yourself and the steering
wheel or instrument panel.
- Do not adjust the driver's or front passeng­
er's seat while the vehicle is moving. Your
seat may move unexpectedly, causing sud­
den loss of vehicle control and personal in­
jury. If you adjust your seat while 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 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
while keeping your knees slightly bent
c::, A in
Why is your seat adjustment so important? on
page
53.
.,. Adjust the backrest so that when you sit with
your back against the backrest, you can still grasp the top of the steering wheel.
.,. 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
c::> page 56. Move the head restraint so that it
is as close to the back of the head as possible. ..,.

Front passenger's seat
Always move the front passenger seat into the
rearmost position.
To avo id contact wit h the airbag while it is de­
p loying, do not sit any closer to the instrument
panel than necessary and always wear the three­
poi nt safety belt provided ad justed correctly . We
recommend that you adjust the passe nger's sea t

• Bring the backrest up to an (a lmost) upright
pos ition .

the risk of an accident
- The power adjustment for the front seats al­
so works with the ignition switched off or
with the ignition key removed. For this rea­
son, children should never be left unattend­ ed in the vehicle - they could be injured!
- Exercise caution when adjusting the seat
height. Unsupervised or careless seat ad­
justment can pinch fingers or hands causing
injuries.
- While the vehicle is moving, the seat backs
of the front seats must not be inclined too
far to the rear because the effect iveness of
the safety be lts and the airbag system is se­
verely compromised -there is a risk of in­
jury.
Seats and storage
- To reduce the risk of injury during sudden
braking or in a collision, the driver and front
passenger should not have their backrests in
the reclined position while driving or riding.
The safety belts and airbag system can pro­
vide the greatest protection possible when
the backrests are in the upright position and
the safety belts are worn correctly. The
more a backrest is reclined, the greater the
risk of injury due to an incorrect seating po­
sition and safety belt position.
