Daytime Running Lamps

The daylight running feature is controlled by the CCU via two daylight running relays located inboard of the passenger compartment fusebox. The CCU switches the relays, to illuminate the dipped beams, side lamps, tail lamps, rear number plate lamp and side marker lamps, when the following conditions are met:

• The engine is running.
• Gearbox selector lever not in Park.
• Headlamps not selected on.

The CCU and the daylight running relays are also used to operate the head/side lamps when they are selected on using the lighting switch on the LH column stalk. The lamps then operate as on non daylight running vehicles, and remain on when the gearbox is in Park and when the engine is switched off.
