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

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.

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.

dimming of the touchscreen is programmable through the
Uconnect system. Refer to “Uconnect Settings” in “Multi-
media” for further details.

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.

Auxiliary Switches — If Equipped
There can be up to five auxiliary switches located in the
lower switch bank of the instrument panel which can be
used to power various electronic devices and PTO (Power
Take Off) – If Equipped. If Power Take Off is equipped, it
will take the place of the fifth Auxiliary switch. Connec-
tions to the switches are found under the hood in the
connectors attached to the auxiliary Power Distribution
Center. You have the ability to configure the functionality of the
auxiliary switches via the instrument cluster display. All
switches can now be configured for setting the switch type
operation to latching or momentary, power source of either
battery or ignition, and ability to hold last state across key
cycles.
NOTE:
Holding last state conditions are met when switch
type is set to latching and power source is set to ignition.

If Engine Fails To Start
If the engine fails to start after you have followed the
“Normal Starting” procedure, it may be flooded. Push the
accelerator pedal all the way to the floor and hold it there
while the engine is cranking. This should clear any excess
fuel in case the engine is flooded.
The starter motor will engage automatically, run for 10
seconds, and then disengage. Once this occurs, release the
accelerator pedal and the brake pedal, wait 10 to 15
seconds, then repeat the “Normal Starting” procedure.
WARNING!
•Never pour fuel or other flammable liquid into the
throttle body air inlet opening in an attempt to start
the vehicle. This could result in flash fire causing
serious personal injury.
•
Do not attempt to push or tow your vehicle to get it
started. Vehicles equipped with an automatic transmis-
sion cannot be started this way. Unburned fuel could
enter the catalytic converter and once the engine has
started, ignite and damage the converter and vehicle.
• If the vehicle has a discharged battery, booster cables
may be used to obtain a start from a booster battery

or the battery in another vehicle. This type of start
can be dangerous if done improperly. Refer to
“Jump-Starting Procedure” in “In Case Of Emer-
gency” for further information.
CAUTION!
To prevent damage to the starter, do not crank the
engine for more than 10 seconds at a time. Wait 10 to 15
seconds before trying again.
If the engine has been flooded, it may start to run, but not
have enough power to continue running when the ignition
button/key is released. If this occurs, continue cranking
with the accelerator pedal pushed all the way to the floor.
Release the accelerator pedal and the ignition button/key
once the engine is running smoothly.
If the engine shows no sign of starting after a 10 second
period of engine cranking with the accelerator pedal held
to the floor, wait 10 to 15 seconds, then repeat the “Normal
Starting” procedure.6
