[ i J 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 windshield wiper lever to any posi­
tion .
• Worn or dirty windshield wiper blades result in streaking. This
can affect the rain sensor * function. Check 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 reactivate the sensor, switch off the interval wiping function, then switch it back
on again.
• The washer fluid nozzles of the windshield washer system are
heated at low temperatures when the ignition is on.
• When stopping temporarily, e.g. at a traffic light, the set speed of
the windshield wipers is automatically reduced by one speed .•
Service position
The windshield wiper blades are replaced in the service
position .

also avoid paint damage to the hood when working on the wipers in
this position .
• Off -the windshield wipers are moved to their initial position
again.
0 Note
Never maneuver your vehicle with the front windshield wiper arms
raised since they will automatically be moved back to their basic
position above a speed of 3 mph (6 km/h) and can scratch the hood.

• Check to make sure there are no objects preventing light from
reaching the inside mirror.
• Do not attach any sticke rs to the windshield in front of the light
sensor*, as this wou ld interfere with both the automatic operation
of the headlights and the automatic dimming of the inside mirror .

parking.
The mirror returns to its initia l pos ition as soon as reverse gear is
disengaged and vehic le speed is above about 9 mph (15 km/h) . T he
mirro r also returns to its initia l p osition if the swi tch is moved to the

I f the position of the mirror surface is changed on a ti lted mirror, this
new pos it ion will be automa tically assigned to the remote key when
the vehicle is taken out of reverse gear.
0 Note
Curved mirror surfaces (convex or spherical*) increase your field of
v iew . Remember that vehicles or o ther objects wi ll appear sma ller
and farther away than when seen in a flat mirror. If you use this
mirror t o estimate distances of following vehic les when changing
lanes, you cou ld estimate incorrectly and cause an acc ident. .,.

pervised use of the cigarette lighter can cause burns -risk of
injury!
• The cigarette lighter works when the ignition is switched off or
with the ignition key removed . Children should never be left unsu­
pervised in the vehicle, or there could be risk of fire!
• The power outlets and therefore the electrical accessories
connected to them operate only with the ignition on. Improper use
of the outlets or of electrical accessories can lead to serious inju­
ries or cause a fire. For this reason, children should never be left
unattended in the vehicle -they could be injured!
0 Note
• To avoid damaging the socket, only use plugs that fit properly .
• Only use the cigarette lighter socket as a power source for elec­
trical accessories for short durations . Use the sockets* in the
vehicle when a power source is needed for longer durations.

& WARNING
• Always remove objects from the instrument panel. Any items
not put away could slide around inside the vehicle while driving or
when accelerating or when applying the brakes or when driving around a corner .
• When you are driving make sure that anything you may have
placed in the center console or other storage locations cannot fall
out into the footwells. In case of sudden braking you would not be
able to brake, depress the clutch or accelerate.

with the driver's view. The coat hooks are designed only for light­
weight clothing. Never hang any clothing with hard, pointed or
heavy objects in the pockets on the coat hooks . During sudden
braking or in an accident - especially if the airbag is deployed -
these objects could injure any passengers inside the vehicle . •
