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 corr ectly 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
Q page 138.
In the following sections, you will see exact ly
how you can best adjust your seats.
There are spec ial regulations and instr uctions for
installing a child safety seat on the front pas­
senger's seat. Always fo llow the information re­
garding child safety provided in
¢page 158,
Child safety.
A WARNING -
Refer to Q page 121, Driving safety for im­
portant information, tips, suggestions and
warnings that you should read and follow for
your own safety and the safety of yo ur pas­
senge rs.
A WARNING
Incorrect seat ing position of the driver and all
other passengers can result in serious person­
al injury .
- Always keep yo ur feet on the floor when the
vehicle is in motion -never pu t your feet on
top of the instrument pane l, out o f 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 sto rage
the seating position is incorrect, this could
result in persona l 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 pan­
el. If you're sitt ing any closer than this, the
airbag system cannot protect you properly.
In addition, the front seats and head re­
stra ints must be adjusted to you r body
he ight so that they can g ive you maximum
p rotection.
- Always try to keep as much dis tance 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 contro l and personal in­
jury. If you ad just your seat while the veh icle
is moving, you are out of pos ition.
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 fo re and aft direction so tha t
you c an ea sil y push the pedals to the floor
while keeping yo ur knees s light ly bent¢ .&.
in
Why is your seat adjustment so important? on
page 59.
.,. Adj ust the seatback so that when you sit with
your back against the seatback, you can still
grasp the top of the steering wheel.
.,. App lies to ve hicles w ith ad justab le head re­
stra ints: Adjust the head rest raint so the upper
edge is as even as possible w ith the top of your
head. If t hat is not possible, try to adjust the
he ad restraint so that it is as close to this pos i­
tion as possible ¢
page 61.
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
59

Sea ts and stor age
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 a irbag while it is de­
p loying, do not sit any closer to the instrument
panel than necessary and a lways 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 (a lmost) upright
position .
Do not ride with the seat reclined.
.,. Applies to vehicles with adjustable head re­
straints: Adjust the head restra int so the upper
edge is as even as poss ible with the top of your
head. If that is not possible, try to adjust the
head restraint so that it is as close to th is posi­
tion as poss ible

- To reduce the risk o f injury in the case of
sudden braking or accident, front passen­
ge rs must never ride in a moving veh icle
with the backrest reclined. Safety belts and
the airbag system only offer maximum pro­
tect ion when the backrest is upr ight and the
safety belts are properly positioned on the body. T he more the backrest is reclined, the
greater the risk of pe rsonal inj ury from an

A WARNING
-Never adjust the driver's or front passeng­

do this while the vehicle is moving, you will
be out of position. Always adjust the driver's
or front passenger's seat when the vehicle is

- Be careful when adjusting the seat height.
Check to see that no one is in the way, or se­

- Because the seats can be electrically adjust­
ed with the ignition off or with the ignition
key removed, never leave children unattend­
ed in the vehicle. Unsupervised use of the
electric seat adjustments may cause serious
injury.
- To reduce the risk of injury in the case of
sudden braking or accident, front passen­
gers must
never ride in a moving vehicle
with the backrest reclined. Safety belts and
the airbag system only offer maximum pro­
tection when the backrest is upright and the
safety belts are properly positioned on the body. The more the backrest is reclined, the
greater the risk of personal injury from an
incorrect seating posit ion and improperly
positioned safety belts .
