Alarm system>If the indicator lamp flashes for
10 seconds when the system is
disarmed: an attempted entry has
been detected in the period since the
system was armed.
Following triggering of an alarm, the
indicator lamp will flash continuously.Avoiding unintentional alarmsThe tilt alarm sensor and interior motion
sensor may be switched off at the same
time to prevent a false alarm from being
triggered (in garages with elevator
ramps, for instance), or when the
vehicle is transported by trailer or train:
Lock the vehicle (arm the alarm system)
twice in succession: press button 2 on
the remote control transmitter twice
(refer to page 40), or turn the key in the
door lock to the right (lock) twice in
succession (refer to page 38).
The indicator lamp lights up briefly and
then flashes continuously. The tilt alarm
sensor and the interior motion sensor
are deactivated for as long as the
system remains armed.
Interior motion sensorThe illustration depicts the transmitter
and receiver of the interior motion
sensor.
In order for the interior motion sensor to
function properly, the windows and
sliding/tilt sunroof must be completely
closed.
Nevertheless, you should deactivate
the interior motion sensor (refer to the
previous column) if you intend to leave
the windows or sliding/tilt sunroof
open.390de153

Electric power windowsOpen and close windowsFrom ignition key position 1:
>Depress the rocker switch until you
feel resistance:
The window continues moving for as
long as you maintain pressure on the
switch.
>Press the rocker switch beyond the
resistance point:
The window moves automatically.
Press the switch a second time to
stop the window.390de055
After the ignition has been switched off:
>You can still operate the windows as
long as neither of the front doors has
been opened. To open the window,
press the switch beyond the resis-
tance point.
Remove the key from the ignition
when you leave the vehicle, so
that children cannot operate the power
windows and possibly injure them-
selves.<
For the convenience mode via the door
lock or the remote control, refer to
pages 38 or 40.Safety featureA contact strip is integrated into the
inner side of each of the upper window
frame sections. If pressure is exerted
against this contact strip while a
window is being raised, the system
will respond by stopping the window
and then retracting it a small distance.
Despite this safety feature, be
extremely careful that the closing
path of the window is not obstructed
whenever it is closed. Otherwise, an
object might not touch the contact strip
in some situations (very thin objects, for
instance).
You can override this safety feature by
pressing the switch beyond the resis-
tance point and holding it.
Because the power windows are sealed
at high pressure to prevent wind noise
when closed, a powerful motor is
required for efficient closing. When
closing the windows, always be sure
that they are not obstructed in any way.
Unsupervised use of these systems can
result in serious personal injury.
Remove the ignition key to deactivate
the electric power windows whenever
you leave the car. Never leave the keys
in the vehicle with unsupervised chil-
dren.
Never place anything that could
obstruct the driver's vision on or next
to the windows.<

Electric power windows Sliding/Tilt sunroof
*
Safety switchWith the safety switch, you can prevent
the rear windows from being opened or
closed via the switch in the rear pas-
senger area (by children, for example).
Press the safety switch whenever
children are riding in the rear of
the vehicle. Careless use of the power
windows can lead to injury.< 390de131
To prevent injuries, exercise care
when closing the sliding/tilt sun-
roof and keep it in your field of vision
until it is shut.
Before leaving the car, switch off the
electric sunroof mechanism by taking
out the ignition key. Do not leave chil-
dren unattended in the vehicle with ac-
cess to vehicle keys. Use of the key can
result in starting of the engine and op-
eration of vehicle systems such as
power sunroof, etc. Unsupervised use
of these systems can result in serious
personal injury.<
You can avoid pressure or drafts in the
passenger compartment when the sun-
roof is open or lifted by keeping the air
vents in the instrument panel open and
increasing the air supply as required.
Refer to pages 108 or 114.
If the sunroof is completely open, air
disturbances may be caused in the ve-
hicle when you are driving at higher
speeds. Close the roof as far as is nec-
essary until this natural phenomenon
ceases.
For the convenience mode via the door
lock or the remote control, refer to
page 38 or 40.
Lifting – opening – closingFrom ignition key position 1, press the
switch or slide it to the desired direction
until you feel resistance.
When lifting, the headliner retracts
several inches.
If the sliding/tilt sunroof is up, then
the headliner cannot be closed.<
After the ignition has been switched off,
you can still operate the sliding/tilt sun-
roof as long as neither of the front
doors has been opened.390de636

Mirrors
The mirror on the passenger's
side features a lens with a more
convex surface than the mirror installed
on the driver's side. When estimating
the distance between yourself and
other traffic, bear in mind that the
objects reflected in the mirror are
closer than they appear. This means
that estimations of the distance to
following traffic should not be regarded
as precise.<
Electric heatersBoth mirrors are heated automatically
with the ignition key in position 2.
Interior rearview mirrorTo reduce glare from vehicles behind
you after dark, tilt the mirror by moving
the small lever.Lighted vanity mirrorFold down the sun visor and slide the
cover panel to the side as required.

By responding to the effects of ambient
light and the glare from following traffic,
this mirror automatically dims through
an infinitely-variable range.
The mirror automatically reverts to its
clear, undimmed setting whenever you
select "Reverse."
For proper functioning of the mirror, be
sure that the two photocells are unob-
structed and clean. One of the photo-
cells (arrow) is positioned in the mirror's
glass, while the other is slightly offset
on the opposite side of the mirror.

Air conditionerTips for a pleasant driving
experienceTemperature 6 is recommended for a
comfortable setting at 707 (226).
Turn the air distribution 7 to the
"6 o'clock" position. Adjust the air sup-
ply 8 to the center setting. Set the out-
lets 2 so that the air flows past you and
is not directed straight at you. Set the
rotary dial between the outlets 2 for the
upper body to a central position so that
cooler air helps prevent fatigue during
the journey.
The following description will lead you
through additional individual adjust-
ments.Temperature
The graduations on the dial
provide general reference val-
ues for the interior tempera-
ture. We recommend 707
(226) as a comfortable setting. When
you start the vehicle, this system ad-
justs the air to the selected temperature
as quickly as possible, and then main-
tains that temperature constantly.
Air distribution
You can direct air to flow onto
the windows , toward the
upper body and into the
footwell . You can also
select all intermediate settings. In the
setting, there is a low flow of air onto
the windows to keep them free of con-
densation. The "6 o'clock" setting is
recommended for normal conditions
(refer to the illustration and overview on
page 108).
Air supply
You can adjust the air supply
over an infinitely-variable
range. The heating and venti-
lation become increasingly
effective as the air supply settings are
increased. In the "0" setting, the blower
and climate control are switched off
and the outside air supply is blocked.
Rear window defroster
When the rear window de-
froster is activated, the indi-
cator lamp comes on. The rear window
defroster switches off automatically.
Cooling
The air is cooled and dehu-
midified and – depending on
the temperature setting – warmed again
with the air conditioner system
switched on. Depending on the
weather, the windshield may fog over
briefly when the engine is started.
Switch off the air conditioner at outside
temperatures below approx. 427
(56). This will help to prevent the
windows from fogging up.
If the windows fog over after switching
the air conditioner off, switch it back
on.
Condensation forms in the air
conditioner system during opera-
tion, which then exits under the vehicle.
Traces of condensed water of this kind
are thus normal.<

Air conditionerRecirculated air mode
If there are unpleasant
odors in the outside air, you
can temporarily block the flow of air.
The system then recirculates the air
currently within the vehicle
If you have a multifunction steering
wheel with the button for recirculated
air, you can also use this button to
switch to the recirculated air mode
(refer to page 25).
If the windows fog over in the re-
circulated air mode, switch the re-
circulated air off and increase the air
supply as required.<
Draft-free ventilation You can adjust the blower controls for
the upper body area to select the opti-
mum airflow rates and directions for
your personal requirements:
Use the rotary dials 1 to open and close
the air outlets over an infinitely-variable
range. You can adjust the direction of
the airflow using the rotary dial 2.
Set the air outlets so that the air flows
past you and is not directed straight at
you.
Rotary dial 3 allows you to control the
temperature of the airflow from these
outlets as desired:
>Turn toward blue – colder.
>Turn toward red – warmer.390de051
Rear passenger area ventilationRotary dial 1 opens the outlets over an
infinitely-variable range. You can
change the direction of the airflow
with the levers 2.
The air that flows out here is somewhat
cooler than the air delivered to the foot-
well.390de355
