If the alarm system is armed, a visual and
audible alarm is triggered by the following:
R Unlocking the vehicle from inside
R Opening a door
R Opening the hood
i The alarm is not switched off, even if you
immediately close the open door that has
triggered it, for example.
X To stop the alarm: press the0036button
on the remote control.
Or
X Insert the key into the ignition lock.
The alarm stops. Tow-away alarm
Operation A visual and audible alarm is triggered if the
inclination of the vehicle changes when the
tow-away alarm is armed. This can be the
case if the vehicle is raised on one side, for
example.
Arming/deactivating The tow-away alarm is automatically armed
approximately 20 seconds after you lock the
vehicle.
The tow-away alarm is automatically deacti-
vated when you unlock the vehicle.
Deactivating X
Remove the key from the ignition lock.
X Press button 0043.
When the button is released, the indicator
lamp on button 0044lights up for about
5 seconds.
X Lock the vehicle.
The tow-away alarm is deactivated.
The tow-away alarm remains deactivated
until you lock the vehicle again.
Deactivate the tow-away alarm when locking
your vehicle and:
R loading and/or transporting the vehicle, on
a ferry or car transporter, for example
R parking on a moving surface, as split-level
garage
This will prevent false alarms. Interior motion sensor
Operation If the armed interior motion sensor detects
motion in the vehicle interior, a visual and
acoustic alarm is triggered. This can happen
if someone reaches into the vehicle interior,
for example.
i
If the interior motion sensor is armed and
the auxiliary heating system (Y page 122)
switches on, a false alarm may occur as a
result of interior temperature monitoring.
In this case, either deactivate the interior
motion sensor or switch off the auxiliary
heating.
Arming X
Close the side windows.
X Make sure that nothing (such as mascots
or coat hangers) are hanging on the rear-
view mirror or on the grab handles on the
headliner.
This will prevent false alarms.
X Lock the vehicle.
The interior motion sensor is armed after
approximately 40 seconds. Theft deterrent locking system

Changing bulbsLights and windshield wipers
The detent positions of the combination
switch correspond to the following wiper
speeds:
0W indshield wipers off
II ntermittent wipe
II Normal wipe
III Rapid wipe
i Canada only:
If the windshield wipers are switched on
and you stop the vehicle, the windshield
wiper speed is reduced. For example, if you
have selected level IIand stop the vehicle,
wiping continues with intermittent wipe
while the vehicle is stationary. If intermit-
tent wipe is selected, the intervals become
longer.
Vehicles with a rain and light sensor:
you can use level Ias the universal setting.
The rain and light sensor sets the appropri-
ate wiping frequency automatically,
according to the intensity of the rain. When
you stop the vehicle, levels IIIand IIare
switched down to level Iautomatically.
The windshield wiper will return to the orig-
inal level when you drive faster than
5 mph (8 km/h).
You can adjust the sensitivity of the rain and
light sensor using the on-board computer
(Y page 196).
Information on checking the washer fluid
level can be found in the "Maintenance and
care" (Y page 257) section. Switching the rear window wiper on/

Important safety notes
G
WARNING
Very hot or very cold air can flow from the air
vents. This could result in burns or frostbite in
the immediate vicinity of the air vents. There
is a risk of injury.
Make sure that all vehicle occupants always
maintain a sufficient distance to the air out-
lets. If necessary, redirect the airflow to
another area of the vehicle interior.
The center and side air vents are adjustable.
On vehicles with a rear-compartment air-con-
ditioning system, you can also adjust the air
vents in the roof duct.
i For virtually draft-free ventilation, adjust
the sliders of the center air vents to the
center position.
In order to ensure the direct flow of fresh air
through the air vents into the vehicle interior,
please observe the following notes:
R keep the air inlet grille on the hood free of
blockages, such as ice, snow or leaves.
R never cover the vents or the ventilation
grilles in the vehicle interior. Setting the center air vents
