When the exterior lamp switch is in the 0 (off) position, only the low beams will be on when the engine is running and it is light outside. When the
ambient light sensor senses dusk, the parking lamps will also be switched on. This may also occur if there is frost on the windshield. In this position, it is
not possible to use the high beams by pressing the exterior lamp switch forward. The high beam flasher does function. Neither the front nor rear fog
lamps can be used.
When the exterior lamp switch is in the AUTO position, the lamps will turn on as described above with one exception. It is possible to use the high
beams by pressing the eAerior lamp switch forward.
The exterior lamp switch must be in the headlamp on position to turn on the fog lamps.
