Lighting Controls
Exterior Lighting Controls
Exterior light controls are listed here in alphabetical
order.
Backup Lights
Backup lights provide a warning to pedestrians and
other drivers that the vehicle is, or is about to, back
up.
Daytime Running Lights
The daytime running lights (DRL), if equipped, are
automatically activated when the ignition is switched
on and the parking brake is released. The DRL oper-
ate until the parking brake is applied or the head-
lights are turned on.
Some vehicles may be equipped with a momentary
DRL override switch. See
Fig. 2.26
. Press the upper
half of the switch to briefly deactivate the DRL.
Fog Lights
Fog lights are designed to reduce glare in foggy con-
ditions. The low-beam headlights must be on in order
to turn the fog lights on. Press the upper half of the
switch to activate the fog lights. See
Fig. 2.26
.
Hazard Warning Lights
The hazard warning light switch tab is located below
the turn signal lever. Pull the tab out to activate the
hazard warning lights. When the hazard warning
lights flash, all turn signal lamps and both of the indi-
cator lights on the control panel will flash. Move the
turn signal lever up or down to cancel the warning
lights.
Headlights
A three-position paddle switch is used to operate the
exterior lights. See
Fig. 2.26
. Move the paddle switch
up to activate the headlights, instrument panel, clear-
ance lights, marker lights, and taillights. To deactivate
all vehicle lighting, ensure the switch is in the middle
position. Move the paddle switch down to activate
only the clearance, instrument panel, marker lights,
and the taillights.
High-Beam Headlights
To activate the high-beam headlights, pull the turn
signal lever towards the driver while the low-beam
headlights are on. Pull the turn signal lever back
again to deactivate the high beams and return to low
beam headlights.
When the high-beam headlights are on, a blue light
illuminates on the instrument cluster.
NOTE: The ignition switch must be on for the
high beams to work.
Marker Light Interrupt
A momentary interrupt switch temporarily deactivates
the marker lights and taillights. With the vehicle lights
on, press and release the interrupt switch to briefly
turn the marker lights and taillights off. To alert the
driver that the switch is functioning, the dash lights
will flash with the marker lights when the switch is
actuated.
