Alarm*
The alarm provides audible and visual warn-
ings if anyone enters the car without a valid
remote control key or manipulates the starter
battery or alarm siren.
When armed, the alarm is triggered if:
a door, the bonnet or the boot lid is
•
14
opened
a movement is detected in the passenger
•
compartment (if fitted with a movement
detector*)
the car is raised or towed away (if fitted
•
with a tilt detector*)
the starter battery's cable is disconnected
•
the siren is disconnected.
•
Alarm signals
When the alarm has been triggered, the fol-
lowing happens:
A siren sounds for 30 seconds or until the
•
alarm is switched off.
Hazard warning flashers flash for
•
5 minutes or until the alarm is switched
off.
If the cause of alarm activation is not rectified,
the alarm cycle is repeated up to 10 times
14 Applies to certain markets.
Alarm indicator
A red LED on the instrument panel indicates
the alarm system's status:
LED not lit – alarm not armed.
•
The LED flashes once every other second
•
– alarm is armed.
After the alarm has been disarmed, the
•
LED flashes rapidly for a maximum of
30 seconds or until ignition position I has
been activated - the alarm has been trig-
gered.
Movement and tilt sensors*
Movement and tilt sensors react to move-
ments inside the car, if the window is broken
14
.
or if anyone tries to steal the wheels or tow
the vehicle away.
KEY, LOCKS AND ALARM
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
passenger compartment heater is used.
To avoid this:
Close the window and sunroof when leav-
•
ing 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
temporarily 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.
In the event of an alarm system fault
If there is a fault in the alarm system,
the driver display shows the symbol
and the message Alarm system
failure Service required
case, contact a workshop - an authorised
Volvo workshop is recommended.
