(D -Interval mode. To extend/shorten the
wiper intervals, move the switch @to the
left/right. In vehicles with a rain sensor* the
wipers turn on in the rain once the vehicle
speed exceeds approximate ly 2 mph (4 km/h) .
The higher the sensitivity of the rain sensor* is
set (switch @to the right), the earlier the
windshie ld w ipers react to moisture on the
windsh ield . In some models, you can sw itch
rain sensor mode
off and switch intermittent
mode on in the MM I*. Select:
I CAR I funct ion
button

the driver. The driver is still responsib le
for manually switching the wipers on ac ­
cording to the visibility cond itions.
- The windshield may not be treated with
water-repell ing windshield coating
agents. Unfavorable conditions, such as
wetness, darkness, low sun, can result in increased glare. Wiper blade chatter is
also possib le.
- Properly functioning windsh ield wiper
blades are required for a clear view and
safe driving
i::> page 51, Replacing
windshield wiper blades.
(D Note
- In the case of frost, check whether the
windshield wiper blades are frozen to
the windshield. Switching on the wind­
shield wipers can damage the wiper
blades!
- Prior to using a car wash, the w indshield
w iper system must be sw itched
off (lever
in position @). This helps to prevent un­
intentional switching on and damage to
the windsh ield wiper system. ..,.

@ Tips
-The windshield wipers are switched off
when the ignition is turned off . Activate
the windshie ld w ipers after the ignit ion
i s sw itched back on by mov ing the w ind­
s hi eld wiper lever to any pos ition .
- Worn or dirty windshie ld wiper blades
result in streak ing. Th is can affect the
rain senso r* function . Check your wind­
s hi eld wiper blades regularly .
- The washer fluid nozzles of the wi nd­
s hi eld washer system are heated at low
temperatures when t he ig nit ion is on.
- When stopp ing temporarily, (e .g . at a
traff ic light) the s et speed of the w ind­
s hi eld wipers is automatically red uced by
one speed.

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
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
Refer to G 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 dr iver and
all other passengers can result in serious
personal inj ury .
- Always keep your feet on the f loor 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 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
strumen t 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 m ust be
adj usted 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 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 you r seat
while the veh icle is moving, yo u are out
of pos it ion.
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 follow ing 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
G &. in Why is your seat adjustment so im ­
portant? on page 54 .
.,. Adjust the seatback so that when you sit
w ith your back against t he seatback, you can
s till grasp the top of the steering whee l.
.. Applies to veh icles with adjustable head re­
straints: Adjust the head restraint so the up­
per edge is as even as possible with the top
of yo ur head. If that is not possib le, try to
adjust the head restraint so that it is as .,.

close to this position as possible
c:>page 57.
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 .
"" Applies to vehicles with adjustable head re­
stra ints: Adjust the head restraint so the up­
per edge is as even as possible with the top
