headlamp actuation, function - GF82.10-P-2009A

MODEL 203, 215, 220.02 /06 /07 /12 /16 /17 

The headlamp actuation encompasses the low and high beams lights.

The headlamps can be actuated:

• Manually with exterior lamp switch (S1s1) (model 203) and exterior lamp switch (S1) (models 215, 220)
• Automatically (sensor-controlled) or in dependency on "circuit 61 ON" (daytime running lamps)

Automatic headlamp actuation 

The automatic driving light actuation is activated:

• By pre-selection on the instrument cluster (A1) (models 215, 220 up to 31.5.00)
• "Auto" position of exterior lamp switch (S1) (models 215, 220 as from 1.6.00) and exterior lamp switch (S1s1) (model 203)

The basic conditions for automatic driving light actuation are:

• Slackening daylight intensity as occurs during dusk,
• Darkness
• Rain or snowfall (automatic light switch daylight sensor (B32/1))
• Failure of automatic light switch daylight sensor (B32/1)

Fog and secondary light influences, e.g. through oncoming traffic, road lighting or through light reflections, do not lead to automatic driving light actuation.

Automatic driving light actuation when starting a journey and during it 

• Automatic driving lamp actuation takes place as from "Circuit 61 ON"
• When the engine is switched off and the circuit status is "circuit 15R ON" or "circuit 15 ON" only the standing lamp is actuated.
• Driving light actuation is disabled as soon as one of the basic prerequisites changes, e.g. when changing from darkness to daylight after driving through a tunnel.

Automatic headlamp actuation at the end of a journey or in darkness 

• After switching off the engine (e.g. "circuit 15 ON", "circuit 15R ON" or "circuit 15C ON") the standing lamp remains on.
• The standing lamp is not switched off until the transmitter key (A8/1) (circuit 15C OFF) is removed.

Daytime running lamps 

The daytime running lamps, forced switch on every time the engine is started (Circuit 61 on), are for statutory reasons in vehicles of the following country versions preset in the instrument cluster (A1) and cannot be deactivated. For all other national versions the daytime running lamps can be activated and deactivated using the left multifunction steering wheel (S110) and right multifunction steering wheel (S111) key groups in the instrument cluster (A1).

Switching off daylight running lights 

The daytime running lamps function is canceled by:

• Engine switched off
• Manual switch-on of the driving lamps with the exterior lamp switch (S1s1) (model 203) and exterior lamp switch (S1) (models 215, 220 as from 1.6.00)

High beam actuation 

The high beam can be switched on as a steady light only when low beam is "ON" by pushing the combination switch (S4) away. The high beam is actuated when the combination switch (S4) is already set to the "high beam ON" position:

• During the journey immediately by switching on the driving lamps
• When the engine is switched off and the "low beam ON" position of the exterior lamp switch (S1s1) (model 203) and of the exterior lamp switch (S1) (models 215, 220 as from 1.6.00) as from position "circuit 15R ON"

Actuation of the headlamp flasher function is dependent on the low beam.
