Battery Saver
To protect the life of your vehicle’s battery, load shedding
is provided for both the interior and exterior lights.
If the ignition is OFF and any door is left ajar for 10 minutes
or the dimmer control is rotated all the way up to the dome
on position for 10 minutes, the interior lights will automati-
cally turn off.
NOTE:Battery saver mode is canceled if the ignition is
ON.
If the headlights remain on while the ignition is cycled OFF,
the exterior lights will automatically turn off after eight
minutes. If the headlights are turned on and left on for
eight minutes while the ignition is OFF, the exterior lights
will automatically turn off.
INTERIOR LIGHTS
Courtesy Lights
Courtesy and dome lights are turned on when the front
doors are opened, when the dimmer control (rotating
wheel on the bottom of the switch) is rotated to the far right
detent position. If your vehicle is equipped with Remote
Keyless Entry, and the unlock button is pushed on the key
fob, the courtesy and dome lights will turn on.
Courtesy/Reading Lights
Both lights in the overhead console and rear passenger
compartment will illuminate as courtesy lights when a
door is opened, when the dimmer control is rotated to the
courtesy light position (full right position), or when the
unlock button is pushed on the Remote Keyless Entry key
fob, if equipped. These lights are also operated individu-
ally as reading lights by pushing on the corresponding
lens.

Dimmer Control
The brightness of the instrument panel as well as the
ambient lighting can be regulated by rotating the dimmer
control to the right (brighter) or to the left (dimmer).
“Party Mode”
When a door is open and the interior lights are on, rotating
the dimmer control all the way left, to the off detent, will
cause all the interior lights to go out. This is also known as
theParty mode because it allows the doors to stay open
for extended periods of time without discharging the
vehicle’s battery. “Parade Mode”
When the headlights are on you can supplement the
brightness of the odometer, trip odometer, radio and
overhead console by rotating the control to the right until
you hear a click. This feature is termed the “Parade” mode
and is useful when headlights are required during the day.
NOTE:
If your vehicle is equipped with a touchscreen, the
dimming of the touchscreen is programmable through the
Uconnect system. Refer to “Uconnect Settings” in “Multi-
media” for further details.
Illuminated Approach
The courtesy lights will turn on when you use the key fob
to unlock the doors or open any door.
This feature also turns on the approach lighting in the
outside mirrors (if equipped). Refer to “Mirrors” in “Get-
ting To Know Your Vehicle” for further information.
The lights will fade to off after approximately 30 seconds,
or they will immediately fade to off once the ignition
switch is turned to ON/RUN from the OFF position.
Dimmer Control
78 GETTING TO KNOW YOUR VEHICLE

The front courtesy overhead console and door courtesy
lights will not turn off if the dimmer control is in the
“Dome ON” position (rotate vertical thumb wheel all the
way to the top detent).
The illuminated entry system will not operate if the
dimmer control is in the “Dome OFF” position (rotate
vertical thumb wheel all the way to the bottom detent).
NOTE:If your vehicle is equipped with illuminated ap-
proach lights under the outside mirrors, they can be turned
off by moving the instrument panel dimmer into the
“Dome Defeat” detent position.
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.

When the vehicle is turned off, be sure to unplug any
equipment as to not drain the battery of the vehicle. All
accessories connected to the outlet(s) should be removed or
turned off when the vehicle is not in use to protect the
battery against discharge.
WARNING!
To avoid serious injury or death:
•Only devices designed for use in this type of outlet
should be inserted into any 12 Volt outlet.
• Do not touch with wet hands.
• Close the lid when not in use and while driving the
vehicle.
• If this outlet is mishandled, it may cause an electric
shock and failure.
CAUTION!
• Many accessories that can be plugged in draw power
from the vehicle’s battery, even when not in use (i.e.,
cellular phones, etc.). Eventually, if plugged in long
enough, the vehicle’s battery will discharge suffi-
ciently to degrade battery life and/or prevent the
engine from starting.
• Accessories that draw higher power (i.e., coolers,
vacuum cleaners, lights, etc.), will discharge the
battery even more quickly. Only use these intermit-
tently and with greater caution.

messages that consist of approximately 60 possible warn-
ing or information messages. These pop up messages fall
into several categories:
•
Five Second Stored Messages
When the appropriate conditions occur, this type of mes-
sage takes control of the main display area for five seconds
and then returns to the previous screen. Most of the
messages of this type are then stored (as long as the
condition that activated it remains active) and can be
reviewed from the “Messages” main menu item. As long as
there is a stored message, an “i” will be displayed in the
instrument cluster display’s compass/outside temp line.
Examples of this message type are “Right Front Turn Signal
Lamp Out” and “Low Tire Pressure.”
• Unstored Messages
This message type is displayed indefinitely or until the
condition that activated the message is cleared. Examples
of this message type are “Turn Signal On” (if a turn signal
