REMOTE UNLOCKING

The vehicle can be unlocked remotely via the Volvo On Call service. If the keys have been locked in the car or lost, the customer can call a Volvo Service Center. The position of the vehicle is determined via the global positioning system module (GPS) in the Telematics system and is transmitted to the Volvo Service Center. The customer must provide a code to the Service Center, which then transmits a signal to the vehicle. This signal activates the central locking system for a certain amount of time. When instructed, the customer must activate the switch in the tailgate/trunk lid. If this is done, the car is unlocked.

The function is market dependent.

Scheme 132: AUTOMATIC LOCKING WHEN DRIVING

Whether the automatic locking function is activated on delivery or not is market dependent. If this function is activated, the side doors lock when the speed exceeds 7 km/h (5 mph). All the doors must be closed, the engine running and the vehicle moving forward. The only exception is the tailgate/trunk lid which can be open. Information about whether the engine is running or not is transmitted by the engine control module (ECM) to the central electronic module (CEM). Indication about whether the engine is driving the car forwards is different in cars with automatic transmissions and manual transmissions. In vehicles with automatic transmissions, the position of the gear selector is received from the transmission control module (TCM). The gear selector must not be in the park (P) or neutral (N) position for automatic locking to function. In vehicles with manual transmissions, the brake control module (BCM) transmits information about vehicle speed to the central electronic module (CEM). The accelerator pedal (AP) must be partly pressed as well for automatic locking to take place.

The door can be unlocked again as normal with the central locking buttons.

Scheme 133: AUTOMATIC RE-LOCKING AFTER UNLOCKING

If the car is unlocked using the remote control or key and the side doors or trunk lid/tailgate are not opened within 2 minutes, the car will be locked automatically. Whether this function is activated on delivery or not depends on the market. This function can be activated later via VIDA (Volvo scan tool) or the infotainment control module (ICM).
