Switch-on conditions

Beginning with terminal 15 ON, the AHL control unit "wakes up". The swivelling of the lights is subject to the following conditions:

• Reverse gear must not  be engaged.
• No system faults must be present. The indicator lamp must not be flashing.
• The D2-S bulbs in both headlight units must be working (the D2-S bulbs are the bulbs for the xenon headlights).
• The vehicle must not be skidding or fishtailing.
• The rain-light sensor must detect darkness.
• Additional switch-on condition: automatic driving lights control is active (light switch in position "A", see above).
