The lever on the left side of the steering column operates the exterior lamps.

The exterior lamp switch has the following four positions:

& (Headlamps): This position turns on the headlamps, parking lamps, and taillamps.

(Parking Lamps): This position turns on the parking lamps and taillamps only.

AUTO (Automatic Headlamp System): This position automatically turns on the Daytime Running Lamps during daytime, and the headlamps, parking lamps, and taillamps at night.

(Off/On): This position turns on the Automatic Headlamp System. In Canada, this only works when a vehicle with an automatic transaxle is in PARK (P).

To turn on the Automatic Headlamp System, turn the switch to off/on. To turn them off, turn the switch to off/on again. This is a momentary control switch that will spring back when released. The Automatic Headlamp System is always turned on at the beginning of an ignition cycle.
