ly the driver's responsibility to monitor
outs ide weather cond itions and to man­
ually activate the wipers as soon as rain
or drizzle reduces visibility through the
windshie ld.

wate r-repellent mate rials. They can in­
crease glare unde r poo r vis ibility condi­
tions such a s wetness, d arkness, or w hen
the sun is low on the hori zon. In addi ­
tion, they can cause the w indshield wip­
ers to chatter.

58 Seat s a nd s tor ag e
Seats and storage
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
you r seat prope rly 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 a irbag system can offer
maximum protection
¢ page 151 .
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 seat on the front pas­
senger's seat. Always fo llow the information
regarding ch ild safety provided in
q page 17 4, Child Safety.
A WARNING
Incorrect seating position of the driver and
all other passengers can result in serious
personal in jury.
- Always keep your feet on the floor when
the vehicle is in motion -never p ut your
f eet on top of the instrument panel, out
of the w indow or on top of the seat cush­
ion . Th is app lies especially to the passen­
gers .
If your seating position is incorrect,
yo u increase the r isk of injury in the case
of sudden braking or an acc ident.
If the
a irbag infla tes and the seating positio n
is incorrect, this could result in personal
injury o r even death.
- It is import ant for bo th 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 s itting any
closer than th is, the a irbag 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 max imum protect ion.
- Always try to keep as much distance as
possible between yourself and the steer­
ing wheel o r inst rument pane l.
- Do not adjust the driver's o r front pas­
senger's seat whi le the vehicle is moving.
Your sea t may move unexpected ly, caus­
ing sudden loss of vehicle cont rol and
personal injury . If yo u adjust yo ur seat
while the veh icle is moving, yo u are out
of posit ion.
Driver's seat '
The correct seat position is important for safe
and relaxed driving.
We recommend tha t you adjus t the dr iver's
seat in the fo llowing manner :
.,. Adjust t he seat in fore and aft direction so
t ha t you can eas ily push the peda ls to the
floor w hile keeping your knees sl igh tly bent
q A in Why is your seat adjustment so im­
portant? on page 58.
.. Adjust the backrest so that when you sit
w ith your back against t he backrest, you can
still grasp the top of the steering wheel.
.. Adjust the head restraint so the upper edge
is as even as poss ible with the top of your
head . If that is not poss ible , try to adjust
t he head restraint so that it is as close to
t his pos it ion as possib le
q page 65.
A WARNING
Neve r place any objects in the dr iver's foot ­
well. An object could get into the pedal
a rea and interfere with pedal function . In
case of sudden braking or an acc ident, you
would not be able to brake or accelerate .
