Operating procedure 

1. Basic requirements:
   • The electronic key in the starter switch of the EIS control module (N73) is set at least to position "2" (terminal 15R).
   • The exterior lamp switch (S1) is set to the driving lights or as of 06.00 the "AUTO" position
     • the standing and parking lamp and the driving light in the lamp units,
     • the standing and parking lamp in the lamp units

       and

     • the license plate lamps are actuated.
   • For trailer couplings the trailer recognition control module switches additional voltage for the trailer's tail lamps and license plate lamps to the trailer hitch's socket, 13-pin.
   • The daytime running light function enables the headlamp flasher only.
2. The combination switch lever (S4) is moved to the high beam position.
3. The steering column module (N80) records the combination switch's position and sends the "Driving lights ON"  signal over the databus (1).
   • left front SAM control module (N10/6),
   • right front SAM control module (N10/7) and the
   • instrument cluster (A1).
4. The left and right SAM control modules actuate the driving light (E1e1 and E2e1) in addition to the low beam lights in the left and right-hand lamp units.
5. The instrument cluster actuates the blue high beam indicator lamp (A1e3) and thus notifies optically that the high beam lights are switched on.

   The instrument cluster (A1) triggers an acoustic warning signal, as for the low beam lights, when the high beam is switched on, the electronic key has been removed and the driver's door is open.

Operational sequence for actuating headlamp flasher 

• The operational sequence when activating the headlamp flasher is equivalent, in relation to the signal flow, to that of the driving light. The only difference lies in the activation of the switching operation. To operate the headlamp flasher the combination switch lever (S4) must be pulled into the switching position opposite the driving light one (LH) and held in this position.
• The headlamp flasher a and therefore the driving light a remains active for as long as the lever is held in the headlamp flasher position.
