Your vehicle is equipped with plastic headlight and fog
light (if equipped) lenses that are lighter and less suscep-
tible to stone breakage than glass lights. Plastic is not as
scratch resistant as glass and therefore different lens clean-
ing procedures must be followed.
To minimize the possibility of scratching the lenses and
reducing light output, avoid wiping with a dry cloth. To
remove road dirt, wash with a mild soap solution followed
by rinsing.
NOTE:If your vehicle is equipped with illuminated ap-
proach lights under the outside mirrors they can be turned
off through the instrument cluster display or the Uconnect
radio. For further information refer to “Instrument Cluster
Display” in “Getting To Know Your Instrument Panel” and
“Uconnect Settings” in “Multimedia”.
CAUTION!
Do not use abrasive cleaning components, solvents,
steel wool or other abrasive materials to clean the
lenses.
Headlights
To turn on the headlights, rotate the headlight switch
clockwise to the headlight position. When the headlight
switch is on, the parking lights, taillights, license plate light
and instrument panel lights are also turned on. To turn off
the headlights, rotate the headlight switch back to the O
(off) position.

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.

If the ABS light does not turn on when the ignition is
placed in the ON/RUN or ACC/ON/RUN position, have
the brake system inspected by an authorized dealer.
— Low Coolant Level Warning Light
This telltale will turn on to indicate the vehicle coolant
level is low.
— Loose Fuel Filler Cap Warning Light — If
Equipped
This light will illuminate when the fuel filler cap is loose.
Properly close the filler cap to disengage the light. If the
light does not turn off, please see your authorized dealer.
— Service 4WD Warning Light — If Equipped
If the light stays on or comes on during driving, it means
that the 4WD system is not functioning properly and that
service is required. We recommend you drive to the nearest
service center and have the vehicle serviced immediately.
Yellow Indicator Lights
— Transmission Temperature Warning Light
This light indicates that the transmission fluid temperature
is running hot. This may occur with severe usage, such as
trailer towing. If this light turns on, safely pull over and stop the vehicle. Then, shift the transmission into PARK
and run the engine at idle or slightly higher until the light
turns off.
WARNING!
If you continue operating the vehicle when the Trans-
mission Temperature Warning Light is illuminated you
could cause the fluid to boil over, come in contact with
hot engine or exhaust components and cause a fire.
CAUTION!
Continuous driving with the Transmission Tempera-
ture Warning Light illuminated will eventually cause
severe transmission damage or transmission failure.
— Rear Fog Indicator — If Equipped
This indicator will illuminate when the rear fog lights are
on.
— TOW/HAUL Indicator Light
This light will illuminate when TOW/HAUL mode is
selected.

— Cargo Light — If Equipped
The cargo light will illuminate when the cargo light is
activated by pushing the cargo light button on the head-
light switch.
— 4WD Low Indicator Light — If Equipped
This light alerts the driver that the vehicle is in the
four-wheel drive LOW mode. The front and rear drive-
shafts are mechanically locked together forcing the front
and rear wheels to rotate at the same speed. Low range
provides a greater gear reduction ratio to provide increased
torque at the wheels.
Refer to “Four-Wheel Drive Operation — If Equipped” in
“Starting And Operating” for further information on four-
wheel drive operation and proper use.
– 4WD Indicator Light — If Equipped
This light alerts the driver that the vehicle is in the
four-wheel drive mode, and the front and rear driveshafts
are mechanically locked together forcing the front and rear
wheels to rotate at the same speed.
— 2WD Indicator Light — If Equipped
This light alerts the driver that the vehicle is in the
two-wheel drive mode.
Green Indicator Lights
— Park/Headlight On Indicator Light
This indicator will illuminate when the park lights or
headlights are turned on.
— Front Fog Indicator Light — If Equipped
This indicator will illuminate when the front fog lights are
on.
— Turn Signal Indicator Lights
When the left or right turn signal is activated, the turn
signal indicator will flash independently and the corre-
sponding exterior turn signal lamps will flash. Turn signals
can be activated when the multifunction lever is moved
down (left) or up (right).
NOTE:
•A continuous chime will sound if the vehicle is driven
more than 1 mile (1.6 km) with either turn signal on.
• Check for an inoperative outside light bulb if either
indicator flashes at a rapid rate.
158 GETTING TO KNOW YOUR INSTRUMENT PANEL

•Any time you store your vehicle or keep it out of service
(i.e., vacation) for two weeks or more, run the air
conditioning system at idle for about five minutes in the
fresh air and high blower setting. This will ensure
adequate system lubrication to minimize the possibility
of compressor damage when the system is started again.
BODYWORK
Protection From Atmospheric Agents
Vehicle body care requirements vary according to geo-
graphic locations and usage. Chemicals that make roads
passable in snow and ice and those that are sprayed on
trees and road surfaces during other seasons are highly
corrosive to the metal in your vehicle. Outside parking,
which exposes your vehicle to airborne contaminants, road
surfaces on which the vehicle is operated, extreme hot or
cold weather and other extreme conditions will have an
adverse effect on paint, metal trim, and underbody protec-
tion.
The following maintenance recommendations will enable
you to obtain maximum benefit from the corrosion resis-
tance built into your vehicle.
What Causes Corrosion?
Corrosion is the result of deterioration or removal of paint
and protective coatings from your vehicle.
The most common causes are:
• Road salt, dirt and moisture accumulation.
• Stone and gravel impact.
• Insects, tree sap and tar.
• Salt in the air near seacoast localities.
• Atmospheric fallout/industrial pollutants.
Body And Underbody Maintenance
Cleaning Headlights
Your vehicle is equipped with plastic headlights and fog
lights that are lighter and less susceptible to stone breakage
than glass headlights.
Plastic is not as scratch resistant as glass and therefore
different lens cleaning procedures must be followed.
To minimize the possibility of scratching the lenses and
reducing light output, avoid wiping with a dry cloth. To
remove road dirt, wash with a mild soap solution followed
by rinsing.
