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

Turn the outside part of the lever with this symbol on it, to operate the lamps. The exterior lamp switch has three positions.

OFF: Turning the switch to this position turns off all lamps and lights, except the Daytime Running Lamps (DRL).

(Parking Lamps): Turning the switch to this position turns on the parking lamps, together with the following:

    • Sidemarker Lamps
    • Taillamps
    • License Plate Lamps
    • Instrument Panel Lights
(Headlamps): Turning the switch to this position turns on the headlamps, together with the previously listed lamps and lights.

AUTO (Automatic Headlamps): Turning the exterior lamps control to AUTO will turn the headlamps, taillamps and parking lamps on and off, while the ignition is on, by sensing how dark it is outside. See "Automatic Headlamp System" later in this section for more information.

Wiper-Activated Headlamps

This feature turns on the low-beam headlamps, instrument panel cluster backlighting and taillamps after the windshield wipers have been in use for approximately six seconds. To operate, the exterior lamps control must be in AUTO and it must be dark enough outside.

When the exterior lamps control is in OFF or the parking lamp position and the windshield wiper control is on (LO, HI or INT), the HEADLAMPS SUGGESTED message will appear on the DIC.

When you turn the key to OFF, the wiper-activated headlamps will immediately turn off. The wiper-activated headlamps will also turn off if you turn the exterior lamps control to OFF or turn off the windshield wipers.

Headlamps on Reminder

If the exterior lamps control is left on, you'll hear a warning chime when you turn the ignition off, remove the key from the ignition and open the driver's door.

Daytime Running Lamps

Daytime Running Lamps (DRL) can make it easier for others to see the front of your vehicle during the day. DRL can be helpful in many different driving conditions, but they can be especially helpful in the short periods after dawn and before sunset. Fully functional daytime running lamps are required on all vehicles first sold in Canada.

A light sensor on top of the instrument panel makes the DRL work, so be sure it isn't covered.

The DRL system will make your high-beam headlamps come on at reduced brightness in daylight when the following conditions are met:

    • The ignition is on,
    • the exterior lamps control is off, and
    • the transaxle is not in PARK (P).

When the DRL are on, only your high-beam headlamps will be on. The parking lamps, taillamps, sidemarker and other lamps won't be on.

With your headlamp control in AUTO when it is dark enough outside, your low-beam headlamps will automatically come on. The other lamps that turn on with your headlamps will also turn on. When it is bright enough outside, the regular lamps will go off, and your high-beam headlamps change to the reduced brightness of DRL.

To turn off all exterior lighting at night when you are parked, turn the exterior lamps control all the way toward OFF. The DRL will turn on automatically and the HEADLAMPS SUGGESTED message will be displayed on the DIC when you move the transaxle out of PARK (P).

If the exterior lamps control is in the parking lamps position at night, only the parking lamps will be on. If the transaxle is out of PARK (P), only the parking lamps will be active and the HEADLAMPS SUGGESTED message will be displayed on the DIC.

As with any vehicle, you should turn on the regular headlamp system when you need it.

Automatic Headlamp System

The automatic headlamp system will keep your headlamps on when it is dark outside and the ignition is in ON.

It's possible that your headlamps may go out if you drive from a dark area into a bright area like a lighted parking lot. If this happens, turn on your headlamps with the exterior lamps control.

Light Sensor

Your automatic headlamps and DRL work with the light sensor on top of the instrument panel. Don't cover it up. If you do it will read "dark" and the automatic headlamp lighting will turn on.

Fog Lamps


Object Number: 822615  Size: A2

To turn on only the front fog lamps, turn the fog lamp band to the single fog lamp symbol. To turn on both the front and rear fog lamps, turn the fog lamp band to the double fog lamp symbol.

Turning on the front fog lamps only will automatically activate the parking lamps. Turning on the front and rear fog lamps will automatically activate the parking lamps and headlamps.

To turn off the fog lamps, turn the band to OFF. The front fog lamps will also turn off when you turn on your high-beam headlamps, but will turn on again when you switch to low beams.

Continuous use of the fog lamps will shorten bulb life. Limit use as necessary.

Exterior Lighting Battery Saver

If the exterior lamps control has been left on, the exterior lamps will turn off approximately 10 minutes after the ignition is turned to OFF and any door has been opened. This protects against draining the battery in case you have accidentally left the headlamps or parking lamps on. If you need to leave the lamps on for more than 10 minutes, use the exterior lamps control to turn the lamps back on after the ignition has been turned to OFF and any door has been opened.
