(D Note
- Curved ( i.e. convex) mirror s urfaces in­
crease yo ur field of view. Remember that
vehicles or other objects will appear
smaller and farther away than when
seen in a flat m irror . If you use this mir­
ror to estimate distances of following ve­
hicles when chang ing lanes, you could
es timate incorrectly and cause an ac ci­
dent.
- If the mirror housing is moved uninten­
tionally (for examp le, w hile pa rking your
vehicle), then yo u must first fold the m ir­
ror elect rically . Do not rea djust the mir ­
ror housing man ually . You cou ld damage

The windshield wiper lever controls both the
windshield wipers and the washer system.

following pos itions:
Intermittent w iping \91 (activating r ain

.,. Move the lever up to position (!) .
.,. Move the interval set switch @, to change
the intervals.

.,. Release the lever. The washer stops and the
w ipers keep go ing for about four seconds.
Turning off the wipers
.,. Move the lever back to position @ .
The w indshield wipers and washer only wo rk
whe n the ign ition is turned on.
If you sw itch
off the ignition with the windshie ld w iper lev-
er sti ll in the interva l wipe position and then
Ill>

come back a while later and drive off, the rain
sensor will reactivate itself after the vehicle
speed has exceeded 4 mph (6 km/h).
The rain sensor* is only activated with the
wiper lever set to position(!). When it starts
to rain, the rain sensor will automatically acti­
vate the intermittent wiping mode.
To reduce the sensitivity of the sensor, move
switch @ down. To increase the sensitivity,
move the switch up. The higher you adjust the
sensitivity, the faster the sensor will react
when it senses moisture on the windshield. The pauses between wiper turns depend not
only on the sensitivity setting, but on the ve­
hicle speed as well.
During brief stops, e.g . at a red light, wiper
motion will automatically be reduced to the
next lower speed . Wipers already turning at
low speed. change to intermittent wiping.
When the ignition is turned on, the washer
jets are heated .
A WARNING
-Wiper blades are crucial for safe driving!
Only when they are in good condition are
they able to clear the windows properly
to provide uncompromising visibility.
Worn or damaged wiper blades are a
safety hazard ¢
page 63, Replacing
windshield wiper blades!
- The light/rain sensor* is only designed to
assist and support the driver.
It remains
entirely the driver's responsibility to
monitor outside weather conditions and
to manually activate the wipers as soon
as rain or drizzle reduces visibility
through the windshield.
- The windshield must not be treated with
water-repellent materials. They can in­
crease glare under poor visibility condi­
tions such as wetness, darkness, or when
the sun is low on the horizon. In addi­
tion, they can cause the windshield wip­
ers to chatter.
Clear vision 61
@ Note
In freezing or near freezing conditions:
- Always check that the wiper blades are
not frozen to the glass before you turn
the wipers on. Loosen a wiper blade
which is frozen in place before operating
the wipers to prevent damage to the
wiper blade or the wiper motor.
- Do not use the wipers to clear a frosted
window. Using the wipers as a conven­ ient ice scraper will destroy the wiper
blades .
- Before you take your vehicle to an auto­
matic car wash, make sure you have the
windshield wiper system switched off (lever in position
0), otherwise the wind­
shield wiper system could get damaged
in the car wash if it should suddenly
come on.
@ Tips
-The windshield wipers are switched off
when the ignition is turned off. Activate
the windshield wipers after the ignition
is switched back on by moving the wind­
shield wiper lever to any position.
- Worn or dirty windshield wiper blades
cause smearing, which can affect the op­
eration of the light/rain sensor*. Check
the condition of your windshield wiper
blades regularly.
-The rain sensor is part of the interval
wiping system. Turning off the ignition
will also deactivate the rain sensor. To re­
activate the sensor, switch off the inter­
val wiping function, then switch it back
on again.
-Applies to vehicles with light/rain sen­
sor: When the wipers are switched on
manually and in rain conditions, the au­
tomatic headlights* turn on¢

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 offe r
maximum protection
¢ page 115 .
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 heed the informa­
tion rega rd ing child safety provided in
¢ page 136, Child Safety .
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 p ut your
feet on top of the instrument panel, out
of the w indow or on top of the seat cush­
ion! This applies espec ially to the passen­
gers .
If your seating position is incorrect
you increase the r isk of injury in the case
of sudden braking or an acc ident.
If the
airbag infla tes and the seating position
is incorrect this could result in personal
injury or 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 to
this, the front seats and head restra ints
must be adjusted to your body height so
that they can give you max imum protec­
tion.
- Always try to keep as much distance as
possible between yourself and the s teer­
ing wheel or instrument pane l.
- Do not adjust the driver's o r fron t pa s­
senger's seat whi le the vehicle is moving.
Your seat may move unexpected ly, caus ­
ing sudden loss of vehicle contro l and
personal injury . If you ad just yo ur 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 fo llowing manner:
.,. Adjust the seat in fo re and aft direction so
t ha t you can easily p ush the peda ls to the
floor wh ile keeping your knee slightly bent
i::> A in Why is your seat adjustment so im­
portant? on page

.,. 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.
.,. Posit io n the head restraint according to the
occupant 's height
<=:>page 70 . For maxi­
mum protection, t he top of the head re­
s t raint shou ld be a t least at eye level, pref ­
erab ly higher and idea lly level with the top
of the head

A WARNING "--
Never place any objects in the dr iver's foot-
well. An object could get into the pedal
area and interfere with pedal function. In
case of sudden braking or an acc ident, you
wo uld 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
p loying, 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:
.,. Move the front passenger seat into the rear ­
most position of the fore and aft adjustment
range
c:::> &. in Why is your seat adjustment
so important? on page
