Exterior Lighting Controls

Headlights

The headlight switch is a rotary switch located to the left of the steering column, above the ignition switch. See Fig..

Headlights: Automatic

If the vehicle is equipped with a rain-light sensor and the headlight switch is in the 'A' position, the low beam headlamps and all exterior lights activate when the outside light decreases to a pre-set level. The feature will activate in low ambient light within two seconds.

For automatic headlights to function, the following conditions must be met:

• the headlight switch is set to automatic,

• the ignition key is set to on,

• ambient light intensity is measured at Lux < 1500.

If the light level increases beyond a pre-set level, the automatic headlight feature will turn off after 30 seconds.

Headlights: Intelligent High-Beam Control

If equipped, intelligent high-beam control activates the high-beams when there is insufficient light and no oncoming traffic and dims the high-beam when an oncoming vehicle or light is detected.

For intelligent high-beams to function, the following conditions must be met:

• The headlamp switch is set to automatic.

• The high-beam headlamps are turned on.

• The forward facing camera and radar have a clear view of objects in front of the vehicle.

If an object is detected in front of the vehicle, the high beams will turn off and a two second timer will start. Once the timer has elapsed, the high-beams will turn on.

Headlight: High-Beam

With the low-beam headlamps on, push the turn-signal lever away from you to turn on the high-beam headlamps. See Fig.. To turn off the high-beam headlamps, pull the lever to the middle position.

With the low-beam headlamps on, pull the lever towards you to flash the high-beam headlamps momentarily.

When the high-beam headlamps are on, a blue telltale illuminates on the instrument cluster.

Headlamps: Auxiliary High Beam Lights

Auxiliary high-beam lights may be located in the front bumper. The auxiliary high beams will illuminate only when the high-beam headlamps are on. They will temporarily switch off when the low-beams are on, then switch back on when the high beams are on again. See Fig. for an image of the auxiliary high-beam switch.

Headlights: Follow Me Home Feature

This feature provides temporary lighting in the path of the headlamps while walking to a building or other destination.

If the Follow Me Home feature is activated, and if the headlamps were on prior to engine shutdown, the low-beam headlamps will remain on for nine seconds after the vehicle is parked. If a vehicle door is opened or closed while this feature is active, the timer will add an additional 10 seconds of lighting.

This feature can be temporarily disabled by turning the ignition switch on, or by cycling the headlamps switch from the off position to one of the other two positions.

Backup Lights

Backup lights activate only when the vehicle is in reverse; they are designed to indicate that you are going to or are backing up.

Daytime Running Lights

Daytime running lights (DRL), if equipped, are automatically activated when the ignition is switched on and the parking brake is released. The daytime running lights turn off when the engine falls below 400 rpm, the parking brake is applied, or the headlamps are turned on.

Daytime running lights are mandatory for vehicles domiciled in Canada. Vehicles domiciled in any other location may have an optional override switch ( See Fig.. ). This switch enables the driver to deactivate the daytime running lights for a limited period of time.

Fog Lights

Fog lights are designed to reduce glare in foggy conditions. The low-beam headlamps must be on in order to turn the fog lights on. Pull the headlight switch out to activate the fog lights. See item 1 in Fig..

Hazard Warning Lights

The hazard warning light switch is located on the dash switch panel. See Fig.. The hazard lights can be activated regardless of the ignition switch position.

To activate the hazard lights, press the center of the switch once. The switch will blink at the same rate that the hazard lights flash. Press the switch again to turn them off.

All the turn signals on the vehicle and trailer will flash simultaneously when the hazard lights are activated.

Marker Lights

Marker lights function as auxiliary safety lights. To turn the marker lights on, turn the headlight switch clockwise past the off position. See Fig..

Marker Interrupt

The marker interrupt switch temporarily flashes the marker lights. The switch is located in the right-hand switch pod of the steering wheel, See item 5, See Fig..

Plow Lights

If equipped, plow lights are typically mounted on the plow frame of snow plows. See Fig. for an image of the dash plow light switch.

Spotlight

If equipped, the spotlight switch is located on the pivoting handle of the spotlight itself. There may be a single spotlight assembly mounted above the driver's door, or one above each door.

Turn Signals

The turn-signal lever is mounted on the left-hand side of the steering column. Pulling the turn-signal lever up activates the right-turn signal; pushing it down activates the left-turn signal.

When a turn signal is activated, the matching green telltale light flashes on the instrument panel.

The turn-signal lever is typically a non-canceling combination turn-signal, windshield wiper/washer switch, and high beam headlight control unit. See Fig..

If the vehicle is equipped with a self-canceling turn signal lever, the lever will automatically return to the neutral position when the steering wheel returns to the straight-ahead position after a turn.

Utility Lights

Utility lights can be swivel-mounted on the upper half of the cab, mounted on the exhaust support, or flush-mounted on the back of the cab or sleeper. See Fig. for an illustration of the utility lights switch.
