There are a number of lamps positioned around the car to mark its position. These are in the headlamps, tail lamps and on the front fenders (US model). The lamps light together with the license plate lighting when the light switch module (LSM) is in parking lamp mode or low beam is on.

The lamps are powered via a directly connected relay on the central electronic module (CEM). The rear parking lamps are supplied with power via two shunts (mounted on the rear electronic module (REM)), one for each side. This is so that the power consumption can be monitored and any fault in the lamps detected. The faults are detected by the rear electronic module (REM).

There are diagnostics for the relay, the rear parking lamps (via the rear electrical module (REM)) and the light switch.
