Locking/unlocking the fuel tank filler cover

Locking and unlocking the fuel tank filler cover takes place at different points depending on the configuration of the vehicle.

Standard locking function 

The fuel tank filler cover is locked 10 minutes after the vehicle is locked and unlocked at the same time as the other doors and hatches. The exception is if the vehicle is locked with one of the inner lock buttons, when the fuel tank filler cover is locked immediately.

2 stage locking function 

The fuel tank filler cover locks automatically after 10 minutes or when the vehicle is locked.

The fuel tank filler cover is unlocked together with the driver's door with the first press on the remote control or with the first turn of the key in the lock cylinder in the driver's door.

Automatic locking of the fuel tank filler cover when the vehicle reaches a speed of 7 km/h (5 mph) can be specified as an automatic function with all configurations.

If the vehicle is equipped with the system for automatic fuel leakage detection then the fuel tank filler cover can only be opened with a switch located on the light switch module (LSM). Light switch module (LSM) communicates in serial with the central electronic module (CEM). Central electronic module (CEM) forwards the request to the rear electronic module (REM).

The cover can only be opened if the speed of the vehicle is less than 16 km/h (10 mph). With one press on the switch it can take up to 1.5 seconds before the cover opens. This is so that overpressure in the fuel tank can be equalized before the fuel tank filler cap is removed.

This function is only available for the American market.
