The headlights only work when the ignition is switched on . While
starting the engine or when switching off the ignition, the head ­
lights will go off and only the side marker lights will be on.
After starting the engine, the xenon headlights are automa tically
adjus ted to the load and a ngle of the vehic le (for example, during
acceleration , braking) . This prevents oncoming traffic from exper i­
encing unnecessary headl ig ht g la re from your xenon head ligh ts .
If the system is not operating properly, a warning symbol in the
Auto -Check Contro l is displayed => page
36.
With the side marke r lights or head ligh ts switched on, the sym bol
