Exterior Lighting

Exterior Lamp Controls

The exterior lamp control is on the instrument panel to the left of the steering column.

Turn the control to the following positions:

O : Turns off the exterior lamps. The knob returns to the AUTO position after it is released. Turn to O again to reactivate the AUTO mode.

In Canada, the headlamps will automatically reactivate when the vehicle is shifted out of P (Park).

AUTO : Automatically turns the exterior lamps on and off, depending on outside lighting.

: Turns on the parking lamps including all lamps, except the headlamps.

: Turns on the headlamps together with the parking lamps and instrument panel lights.

IntelliBeam System

If equipped, this system turns the vehicle's high-beam headlamps on and off according to surrounding traffic conditions. The system turns the high-beam headlamps on when it is dark enough and there is no other traffic present.

This light comes on in the instrument cluster when the IntelliBeam system is enabled.

Turning On and Enabling IntelliBeam

To enable the IntelliBeam system, press on the turn signal lever when it is dark outside and the exterior lamp control is in AUTO or .

Driving with IntelliBeam

The system only activates the high beams when driving over 40 km/h (25 mph). The blue high-beam on light appears on the instrument cluster when the high beams are on.

There is a sensor near the top center of the windshield that automatically controls the system. Keep this area of the windshield clear of debris to allow for best system performance.

The high-beam headlamps remain on, under the automatic control, until one of the following occurs:

  • The system detects an approaching vehicle's headlamps.
  • The system detects a preceding vehicle's taillamps.
  • The outside light is bright enough that high-beam headlamps are not required.
  • The vehicle's speed drops below 20 km/h (12 mph).
  • The IntelliBeam system is disabled by the button on the turn signal lever. If this happens, pressbon the turn signal lever when the exterior lamp control is in the AUTO or 2 position to reactivate the IntelliBeam system. The instrument cluster light will come on to indicate the IntelliBeam system is reactivated.

The high beams may not turn off automatically if the system cannot detect another vehicle's lamps because of any of the following:

  • The other vehicle's lamps are missing, damaged, obstructed from view, or otherwise undetected.
  • The other vehicle's lamps are covered with dirt, snow, and/or road spray.
  • The other vehicle's lamps cannot be detected due to dense exhaust, smoke, fog, snow, road spray, mist, or other airborne obstructions.
  • The vehicle's windshield is dirty, cracked, or obstructed by something that blocks the view of the light sensor.
  • The vehicle is loaded such that the front end points upward, causing the light sensor to aim high and not detect headlamps and taillamps.
  • Driving on winding or hilly roads.

The automatic high-beam headlamps may need to be disabled if any of the above conditions exist.

Adaptive Headlight System

If equipped, this Adaptive Headlight System allows the high beam to function as the main driving light at night. The sensor in the windshield detects the lights of oncoming or preceding vehicles.

The system turns on all the high-beam headlamp LED segment when it is dark enough and there is no other traffic present.

This light comes on in the instrument cluster when the Adaptive Headlight System is enabled.

Turning On and Enabling the Adaptive Headlight System

To enable the Adaptive Headlight System, press on the turn signal lever when it is dark outside and the exterior lamp control is in AUTO or .

Driving with the Adaptive Headlight System

The system only activates the high beams when driving over 40 km/h (25 mph). There is a sensor near the top center of the windshield that automatically detects the lights of oncoming and preceding vehicles. Keep this area of the windshield clear of debris to allow for best system performance.

Individual segments of the headlamp high beam are faded out according to the traffic situation, preventing high beam light from glaring oncoming or preceding traffic. This gives the best light distribution without glaring other road users.

The Adaptive Headlight System remains on, under the automatic control, until one of the following situations occurs:

  • Fog Lamps are turned On.
  • The outside light is bright enough that high-beam headlamps are not required.
  • The vehicle's speed drops below 20 km/h (12 mph).
  • The Adaptive Headlight System is disabled by the button on the turn signal lever. If this happens, press bon the turn signal lever when the exterior lamp control is in the or AUTO or 2 position to reactivate the Adaptive Headlight System. The instrument cluster light will come on to indicate the Adaptive Headlight System is reactivated.

The high beams may not turn off automatically if the system cannot detect another vehicle's lamps because of any of the following:

  • The other vehicle's lamps are missing, damaged, obstructed from view, or otherwise undetected.
  • The other vehicle's lamps are covered with dirt, snow, and/or road spray.
  • The other vehicle's lamps cannot be detected due to dense exhaust, smoke, fog, snow, road spray, mist, or other airborne obstructions.
  • The vehicle's windshield is dirty, cracked, or obstructed by something that blocks the view of the light sensor.
  • The vehicle is loaded such that the front end points upward, causing the light sensor to aim high and not detect headlamps and taillamps.
  • The vehicle is being driven on winding or hilly roads.

The Adaptive Headlight System may need to be disabled if any of the above conditions exist.

Town Light

Activated automatically in situations with low exterior ambient light. The light is wide and symmetrical. The special beam pattern is designed to avoid glare for other road users.

Country Light

Activated automatically when low beams come on. This is the normal low beam light pattern.

The illumination of the current lane and the side of the road is improved, reducing glare to oncoming and preceding vehicles. The high beams may not turn off automatically if the system cannot detect another vehicle's lamps because of any of the following:

  • The other vehicle's lamps are missing, damaged, obstructed from view, or otherwise undetected.
  • The other vehicle's lamps are covered with dirt, snow, and/or road spray.
  • The other vehicle's lamps cannot be detected due to dense exhaust, smoke, fog, snow, road spray, mist, or other airborne obstructions.
  • The vehicle's windshield is dirty, cracked, or obstructed by something that blocks the view of the light sensor.
  • The vehicle is loaded such that the front end points upward, causing the light sensor to aim high and not detect headlamps and taillamps.
  • Driving on winding or hilly roads.

The automatic high-beam headlamps may need to be disabled if any of the above conditions exist.

Exterior Lamps Off Reminder

A warning chime sounds if the driver door is opened while the ignition is off and the exterior lamps are on.

Headlamp High/Low-Beam Changer

: Push the turn signal lever away from you and release, to turn the high beams on. To return to low beams, push the lever again or pull it toward you and release.

This indicator light turns on in the instrument cluster when the high-beam headlamps are on.

Flash-to-Pass

To flash the high beams, pull the turn signal lever toward you, and release.

Daytime Running Lamps (DRL)

DRL can make it easier for others to see the front of the vehicle during the day. The DRL system comes on when the following conditions are met:

  • The ignition is on.
  • The exterior lamp control is in AUTO.
  • The transmission is not in P (Park).
  • The light sensor determines it is daytime.

When the DRL system is on, only the DRL are on. The taillamps, sidemarker lamps, instrument panel lights, and other lamps will not be on.

When it begins to get dark, the automatic headlamp system switches from DRL to the headlamps.

To turn off the DRL, turn the exterior lamp control to the off position and then release. For vehicles first sold in Canada, off will only work when the vehicle is parked.

Automatic Headlamp System

When the exterior lamp control is set to AUTO and it is dark enough outside, the headlamps come on automatically.

There is a light sensor on top of the instrument panel. Do not cover the sensor; otherwise the headlamps will come on when they are not needed. The system may also turn on the headlamps when driving through a parking garage or tunnel. When it is bright enough outside, the headlamps will turn off or may change to Daytime Running Lamps (DRL). The automatic headlamp system turns off when the exterior lamp control is turned to O or the ignition is off.

Lights On with Wipers

If the windshield wipers are activated in daylight with the engine on, and the exterior lamp control is in AUTO, the headlamps, parking lamps, and other exterior lamps come on. The transition time for the lamps coming on varies based on wiper speed. When the wipers are not operating, these lamps turn off. Move the exterior lamp control to O or ; to disable this feature.

Adaptive Forward Lighting (AFL)

On vehicles with the AFL system, the headlamps move horizontally while turning the steering wheel to provide greater road illumination in curves.

To activate AFL, set the exterior lamp control to the AUTO or 2 position. To adjust the AFL setting, see Vehicle Personalization 0 109.

Moving the control out of the AUTO or 2 position will deactivate the system. Headlamps can move horizontally when the vehicle speed is greater than approximately 3 km/h (2 mph). Headlamps will not move horizontally when the transmission is in R (Reverse).

Hazard Warning Flashers

A: Press this button to make the front and rear turn signal lamps flash on and off. Press again to turn the flashers off. The hazard warning flashers turn on automatically if the airbags deploy.

Turn and Lane-Change Signals

Move the lever all the way up or down to signal a turn. An arrow on the instrument cluster flashes in the direction of the turn or lane change. Raise or lower the lever until the arrow starts to flash to signal a lane change. Hold it there until the lane change is completed. If the lever is briefly pressed and released, the turn signal flashes three times. The turn and lane-change signal can be turned off manually by moving the lever back to its original position. If after signaling a turn or lane change, the arrow flashes rapidly or does not come on, a signal bulb may be burned out.

Replace any burned out bulbs. If a bulb is not burned out, check the fuse. See Fuses and Circuit Breakers 0 273.
