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. This position must be selected in order for the Wiper Activated Headlamps to be activated. See Wiper Activated Headlamps .

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

When operating in AUTO, a momentary turn of the switch to off/on will turn off the Automatic Headlamp System. Turn the switch to off/on again will turn the Automatic Headlamp System back on. The Automatic Headlamp System is always turned on at the beginning of an ignition cycle.
