Activated alarm is triggered if:
If there is a fault in the alarm system then the information display in the combined instrument panel shows a message. In which case, contact a workshop - an authorised Volvo workshop is recommended.
The movement sensors trigger an alarm in the event of movement in the passenger compartment - 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/sunroof when leaving the car. If the car's integrated passenger compartment heater (or a portable electric heater) shall be used - direct the airflow from the air vents so that they are not pointing upwards in the passenger compartment. Alternatively, reduced alarm level can be used, see Reduced alarm level.
One of the alarm sensors is located beneath the cup holder in the centre console, this sensor is sensitive to metals.
Avoid keeping coins, keys or similar metal objects in the cup holder in the centre console as these may cause accidental alarm activation.
