P when the ignition is switched off

P is engaged automatically when the ignition is switched off. When in an automatic car wash, e.g., ensure that the ignition is not switched off accidentally.

The ignition automatically cuts off while the vehicle is stationary and the engine is stopped:

• When locking the vehicle, and when the low beams are activated.
• Shortly before the battery is discharged completely, so that the engine can still be started. This function is only available when the low beams are turned off.
• When opening or closing the driver door, if the driver's safety belt is unbuckled and the low beams are turned off.
• While the driver's safety belt is unbuckled with driver's door open and low beams off.

The low beams switch to parking lights after approx. 15 minutes of no use.
