Headlamp switch-off delay, function - GF80.20-P-2003T

Model 211.0/2 

Exterior light switch-off delay 

The function serves to illuminate the surrounding area with parking lamps, taillamp, license plate lights and fog lamps after leaving the vehicle.

The time interval can be adjusted in the instrument cluster (A1).

The time interval can be set in increments of 15 s from 0 s to 60 s.

Function prerequisites: 

• Headlamp switch-off delay is activated via instrument cluster (A1).
• C. 61 and c. 15 OFF
• Rain/light sensor (B38/2) signals "darkness"

Operating procedure 

If the function prerequisites are present, the headlamp switch-off delay feature is active for 60 s. This time is independent of the time interval set in the instrument cluster (A1).

When a door or the trunk lid are opened the time for headlamp switch-off delay is started again. This applies each time a door is opened within the expiration time. When the last door is closed, the time interval selected in the instrument cluster (A1) is activated.

Interrupting function (exiting discretely) 

When the ignition c. 15 ON is switched on and off, the headlamp switch-off delay feature is interrupted until the next function prerequisite.

If an alarm of the anti-theft alarm system (ATA) is deployed, the headlamp switch-off delay is also interrupted. Only on vehicles with code (551a) anti-theft alarm (ATA)

Deactivate function 

When the time interval is set to "0 s" in the instrument cluster (A) the headlamp switch-off delay feature is deactivated
