GETTING TO KNOW YOUR VEHICLE55
HEADLIGHT DELAY
To assist when exiting the vehicle, the headlight
delay feature will leave the headlights on for up
to 90 seconds. This delay is initiated when the
ignition is placed in the OFF position while the
headlight switch is on, and then the headlight
switch is cycled off. Headlight delay can be
cancelled by either turning the headlight switch
on then off, or by placing the ignition in the ON
position.
NOTE:
This feature can be programmed through the
Uconnect system Úpage 237.
The headlight delay feature is automatically
activated if the headlight switch is left in the
AUTO position when the ignition is placed in
the OFF position.
LIGHTS-ON REMINDER
If the headlights, parking lights, or cargo lights
are left on after the ignition is placed in the OFF
position, the vehicle will chime when the
driver’s door is opened.
FOG LIGHTS — IF EQUIPPED
The fog lights are turned on by rotating the
headlight switch to the parking light or headlight
position and pushing in the fog light button on
the headlight switch.

Fog Light Button

The fog lights will operate only when the parking
lights are on or when the vehicle headlights are
on low beam. An indicator light located in the
instrument cluster will illuminate when the fog
lights are on. The fog lights will turn off when the
button is pushed a second time, when the
headlight switch is rotated to the off position, or
the high beam is selected. If the fog lights are off, one of the fog lights will
illuminate depending on the direction in which
the vehicle is turning. This will provide
increased visibility while turning, depending on
the angle of the steering wheel.
TURN SIGNALS
Move the multifunction lever up or down to
activate the turn signals. The arrows on each
side of the instrument cluster flash to show
proper operation.

there is a very fast flash rate, check for a defec
-
tive outside light bulb.
LANE CHANGE ASSIST — IF EQUIPPED
Lightly push the multifunction lever up or down,
without moving beyond the detent, and the turn
signal will flash three times then automatically
