Headlamps On Reminder

If you leave the exterior lamp control on, remove the key from the ignition and open the driver's door, you will hear a continuous warning chime. The chime will turn off when the lamps are turned off.

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 monitors the exterior light level for the operation of DRL and Twilight Sentinel®, 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 DRL are on, only your high-beam headlamps will be on. The parking lamps, taillamps, sidemarker and other lamps won't be on. Your instrument panel won't be lit up either.

When it's dark enough outside, your high-beam headlamps will change to low-beam headlamps at full brightness. The other lamps that turn on with your headlamps will also turn on. When it's bright enough outside, the regular lamps will turn off, and your high-beam headlamps change to the reduced brightness of DRL.

To idle your vehicle with the DRL off, shift the transaxle into PARK (P). The DRL will stay off until you shift out of PARK (P).

To turn off all exterior lighting at night when you are parked, turn off the exterior lamp control and slide the Twilight Sentinel control all the way to the left. When released, the control will return to the Twilight Sentinel minimum delay position and the lights will turn off.

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

Cornering Lamps

The cornering lamps come on when the headlamps or parking lamps are on and you signal a turn with the multifunction lever. They provide more light for cornering.

Twilight Sentinel


Object Number: 810835  Size: A2

Twilight Sentinel® turns your headlamps on and off by sensing how dark it is outside.

To operate this feature, slide the control to any position to vary the lamp timeout.

You can set the delay time from only a few seconds to three minutes. If you move the control all the way to MAX, your lamps will remain on for three minutes after you turn off your engine. If you move the control almost all the way in the other direction, so it's just on, the lamps will go off quickly when you turn off your engine. Sliding the control to OFF, turns off the Twilight Sentinel® feature.

Light Sensor

Your Twilight Sentinel® and DRL work with the light sensor on top of the instrument panel. Don't cover it up. If you do, it will sense "dark" and the headlamps will come on.
