Daytime Running Lights (DRL) (Discovery 3)

The DRL system is a low beam headlight with full brightness, which is constantly switched on while driving. The DRL system is mandatory in a number of countries and, depending on the market, can have one of two versions.

DRL system for the Canadian market

The DRL system for this market uses full-brightness low beam headlights. The side lights and registration plate lights are also switched on, but the instrument panel lighting is not switched on. The DRL system is activated when the following parameters are met:

• On vehicles with a manual transmission, the parking brake is released; on vehicles with an automatic transmission, the selector is not in the PARK position.
• The ignition switch is in position II
• The central switching unit receives a signal confirming the engine is running
• The light switch is in the off position or in the parking light on position.

NOTE: When the light switch is turned to the headlights position, the DRL system is turned off and the headlights and parking lights are controlled normally.

NOTE: Adaptive Headlights (AFS) (if any) do not work when the DRL system is on.

NOTE: High beam flashing is still possible while the DRL system is operating. (using the left multifunction steering column switch). Permanent switching on of the high beam headlights using the left multifunction steering column switch becomes impossible.

The DRL system is switched off if the parking brake is applied on a vehicle with a manual transmission, or if the selector lever is moved to the PARK position on a vehicle with an automatic transmission. This reduces the drain on the battery during long stops with the engine running at low outside temperatures. The DRL system is restored when the parking brake is released or the selector lever is moved out of the PARK position.

DRL system for Denmark, Holland, Norway, Sweden and Finland

The DRL system for these markets uses full-brightness low beam headlights. The front, rear and license plate lights are also switched on, but the instrument panel lighting is not switched on. The DRL system is activated when the following parameters are met:

• The ignition switch is in position II
• The central switching unit receives a signal confirming the engine is running
• The light switch is in the off position

NOTE: High beam flashing is still possible while the DRL system is operating. (using the left multifunction steering column switch). Permanent switching on of the high beam headlights using the left multifunction steering column switch becomes impossible.

If the light switch is set to the headlight or parking light position, the DRL system is switched off and the headlights and parking lights are controlled in the normal manner.
