KEY, LOCKS AND ALARM
|| Movement and tilt sensors*
Movement and tilt sensors react to movements
inside the car, if the window is broken or if any-
one tries to steal the wheels or tow the vehicle
away.
The movement sensor triggers an alarm in the
event of movement in the passenger compart-
ment - air currents are also registered. For this
reason the alarm is triggered if the car is left with
a window or the sunroof* open or if the passen-
ger compartment heater is used.
To avoid this:
Close the window and sunroof when leaving
•
the car.
If the passenger compartment or parking
•
heater is to be used – direct the airflow from
the air vents so that they do not point
upwards in the passenger compartment.
Alternatively, use a reduced alarm level to tempo-
rarily deactivate the movement and tilt sensors.
Also switch off the movement and tilt sensors
when the car is being transported on a ferry or
train as these movements may affect the car and
trigger the alarm.
16 Applies to cars with keyless locking and unlocking*.

NOTE
Do not attempt to repair or alter components
in the alarm system yourself. Any such
attempts may affect the terms of the insur-
ance.
