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.
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 cancelled 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 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. 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 the Party
mode because it allows the doors to stay open for extended
periods of time without discharging the vehicle’s battery.
The brightness of the instrument panel as well as the
ambient lighting can be regulated by rotating the dimmer
control right (brighter) or left (dimmer). When the head-
lights 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.

Battery Saver On/Battery Saver Mode Message —
Electrical Load Reduction Actions — If Equipped
This vehicle is equipped with an Intelligent Battery Sensor
(IBS) to perform additional monitoring of the electrical
system and status of the vehicle battery.
In cases when the IBS detects charging system failure, or
the vehicle battery conditions are deteriorating, electrical
load reduction actions will take place to extend the driving
time and distance of the vehicle. This is done by reducing
power to or turning off non-essential electrical loads.
282 UNDERSTANDING YOUR INSTRUMENT PANEL

Load reduction is only active when the engine is running.
It will display a message if there is a risk of battery
depletion to the point where the vehicle may stall due to
lack of electrical supply, or will not restart after the current
drive cycle.
When load reduction is activated, the message “Battery
Saver On” or “Battery Saver Mode” will appear in the
instrument cluster.
These messages indicate the vehicle battery has a low state
of charge and continues to lose electrical charge at a rate
that the charging system cannot sustain.
NOTE:
•The charging system is independent from load reduc-
tion. The charging system performs a diagnostic on the
charging system continuously.
• If the Battery Charge Warning Light is on it may indicate
a problem with the charging system. Refer to “Battery
Charge Warning Light” in “Understanding Your Instru-
ment Panel” for further information. The electrical loads that may be switched off (if equipped),
and vehicle functions which can be affected by load
reduction:
•
Heated Seat/Vented Seats/Heated Wheel
• Heated/Cooled Cup Holders — If Equipped
• Rear Defroster And Heated Mirrors
• HVAC System
• 115V AC Power Inverter System
• Audio and Telematics System
Loss of the battery charge may indicate one or more of the
following conditions:
• The charging system cannot deliver enough electrical
power to the vehicle system because the electrical loads
are larger than the capability of charging system. The
charging system is still functioning properly.
• Turning on all possible vehicle electrical loads (e.g.
HVAC to max settings, exterior and interior lights,
overloaded power outlets +12V, 115V AC, USB ports)
during certain driving conditions (city driving, towing,
frequent stopping).

After Driving Off-Road
Off-road operation puts more stress on your vehicle than
does most on-road driving. After going off-road, it is
always a good idea to check for damage. That way you can
get any problems taken care of right away and have your
vehicle ready when you need it.
•Completely inspect the underbody of your vehicle.
Check tires, body structure, steering, suspension, and
exhaust system for damage.
• Inspect the radiator for mud and debris and clean as
required.
• Check threaded fasteners for looseness, particularly on
the chassis, drivetrain components, steering, and sus-
pension. Retighten them, if required, and torque to the
values specified in the Service Manual.
• Check for accumulations of plants or brush. These things
could be a fire hazard. They might hide damage to fuel
lines, brake hoses, axle pinion seals, and propeller shafts.
• After extended operation in mud, sand, water, or similar
dirty conditions, have the radiator, fan, brake rotors,
wheels, brake linings, and axle yokes inspected and
cleaned as soon as possible.
WARNING!
Abrasive material in any part of the brakes may cause
excessive wear or unpredictable braking. You might
not have full braking power when you need it to
prevent a collision. If you have been operating your
vehicle in dirty conditions, get your brakes checked
and cleaned as necessary.
• If you experience unusual vibration after driving in
mud, slush or similar conditions, check the wheels for
impacted material. Impacted material can cause a wheel
imbalance and freeing the wheels of it will correct the
situation.
WINCH USAGE — POWER WAGON ONLY
(IF EQUIPPED)
Things To Know Before Using Your Winch
General Winch Information
Your vehicle is equipped with an electric vehicle recovery
winch. This winch uses the electrical power from the
vehicle charging system to power a motor that winds wire
rope into the winch drum via planetary gear reduction. By
nature, a winch is capable of generating very high forces
474 STARTING AND OPERATING

and should be used with care. Do not operate the winch
without reading and understanding the complete winch
owner’s manual.
Tensioning The Wire Rope
The winch rope must be properly tensioned before use.
Follow the instructions below to tension the rope:
1. Un-spool the wire rope leaving five wraps of rope on thewinch drum.
2. Attach the hook to a suitable anchor point.
CAUTION!
Be certain the anchor will withstand the load required
to tension the wire rope.
3. Apply at least 500 lbs (227 kg) of tension to the rope while winding the rope. Always use care to ensure the
rope does not pile up on one side of the drum and is
neatly wound onto the drum.
CAUTION!
Wire rope must spool on the winch drum in the
direction indicated on the drum rotation decal on the
winch.
Low Voltage Interrupt
Your winch is equipped with a device that will interrupt
winch function if the vehicle charging system voltage
drops to a low level. The winch will not power-in or out for
30 seconds if this device is tripped. If the interrupt is
tripped, the vehicle should be operated at high idle for a
few minutes to allow the vehicle charging system to
recover before continuing to winch.
Winch Motor Thermal Protection
Your winch is equipped with a thermal protection device in
the motor. If the winch is operated for an excessive
duration, the device may interrupt motor function to
protect the winch motor. During this time the winch will
power-out but will not power-in. Allow the winch motor to
cool for a few minutes before continuing to winch. The
winch will resume normal function once the motor cools.

STARTING AND OPERATING 475

1.Motor: The winch motor is powered by the vehicle
charging system and features a thermal protection
switch that automatically stops motor function in the
power-in direction if the motor gets too hot.
2. Remote Socket: The remote socket allows the remote
control to be attached to the control pack to allow the
winch to function.
3. Winch Drum With Integral Brake: The winch drum
allows the wire rope to be stored on the winch and
transmits force to the wire rope. The winch is equipped
with an integral brake that will stop rotation of the
winch drum if the winch motor is stopped.
4. 3-Stage Planetary Gear Set: Provides balance between
speed and pulling power.
5. Wire Rope: The wire rope allows the winch to be
connected to an anchor to provide a pulling force.
6. Clutch Lever: The clutch lever allows the winch drum to
be disconnected from the winch motor to allow the wire
rope to be pulled from the winch by hand. 7.
Remote Control: The remote control provides the inter-
face between the winch operator and the winch. The
remote control provides the ability to power the winch
in, out, and stop the winch. To operate the winch, the
toggle switch is pressed down to power the winch in
and up to power the winch out. The winch will stop if
the switch is left in the neutral (center) position.
CAUTION!
If not installed, the hook strap must be placed on the
hook.
Fairlead: The fairlead acts as a guide for the wire rope and
minimizes damage to the rope.

Jump-Starting Procedure
WARNING!
Failure to follow this jump-starting procedure could
result in personal injury or property damage due to
battery explosion.
CAUTION!
Failure to follow these procedures could result in
damage to the charging system of the booster vehicle
or the discharged vehicle.
Connecting The Jumper Cables
1. Connect the positive (+)end of the jumper cable to the
positive (+)post of the discharged vehicle.
NOTE: Do not jump off fuses. Only jump directly off
positive post.
2. Connect the opposite end of the positive (+)jumper
cable to the positive (+)post of the booster battery.
3. Connect the negative (-)end of the jumper cable to the
negative (-)post of the booster battery. 4. Connect the opposite end of the negative
(-)jumper
cable to a good engine ground (exposed metal part of
the discharged vehicle’s engine) away from the battery
and the fuel injection system.
WARNING!
Do not connect the jumper cable to the negative (-) post
of the discharged battery. The resulting electrical spark
could cause the battery to explode and could result in
personal injury. Only use the specific ground point, do
not use any other exposed metal parts.
5. Start the engine in the vehicle that has the booster battery, let the engine idle a few minutes, and then start
the engine in the vehicle with the discharged battery.
CAUTION!
Do not connect jumper cable to any of the fuses on the
positive battery terminal. The resulting electrical cur-
rent will blow the fuse.
6. Once the engine is started, remove the jumper cables in the reverse sequence:
