Interior Roof Lighting

Inside there are a number of lamps with different purposes. There are up to four lamps which light when the general lighting is on.

Two of the reading lamps, (front left and front right) are in a unit in the roof immediately above the rear view mirror. The two rear reading lamps (option, market dependent) are in the roof above the rear seat.

The lighting time from when the door is unlocked or closed or from when the engine is switched off is 30 seconds.

The lighting time from the door being left open or from a lamp being activated with a button until the interior lighting goes out is 5 minutes.

For the inner roof lighting to work, the relay for interior lighting must be activated. The central electronic module (CEM) activates the relay via an output.
