Headlight Delay
To aid in your exit, your vehicle is equipped with a
headlight delay that will leave the headlights on for
approximately up to 90 seconds. This delay is initiated
when the ignition is turned off while the headlight switch
is on, and then the headlight switch is cycled off. Headlight
delay can be canceled by either turning the headlight
switch on then off, or by turning the ignition to the
ON/RUN position.
NOTE:This feature can be programmed through the
Uconnect system. Refer to “Uconnect Settings” in “Multi-
media” for further information.
Lights-On Reminder
If the headlights, parking lights or cargo lights are left on
after the ignition is turned OFF, a chime will sound 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 headlight rotary control. 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 display
will illuminate when the fog lights are on. The fog lights
will turn off when the switch is pushed a second time,
when the headlight switch is rotated to the off position, or
the high beam is selected.

WINDSHIELD WIPERS AND WASHERS
Windshield Wipers
The wipers and washers are operated by a switch in the
multifunction lever. Turn the end of the lever to select the
desired wiper speed. Rotate the end of the lever upward, to the first detent past
the intermittent settings for low-speed wiper operation.
Rotate the end of the lever upward to the second detent
past the intermittent settings for high-speed wiper opera-
tion.
Intermittent Wiper System
The intermittent feature of this system was designed for
use when weather conditions make a single wiping cycle,
with a variable pause between cycles, desirable. For maxi-
mum delay between cycles, rotate the control knob upward
to the first detent.
The delay interval decreases as you rotate the knob until it
enters the low continual speed position. The delay can be
regulated from a maximum of about 18 seconds between
cycles, to a cycle every one second. The delay intervals will
double in duration when the vehicle speed is 10 mph
(16 km/h) or less.
Windshield Washers
To use the windshield washer, push the washer knob,
located on the end of the multifunction lever, inward to the
second detent. Washer fluid will be sprayed and the wiper
will operate for two to three cycles after the washer knob is
released from this position.
