Accessory Power Outlet(s)
Accessory power outlets can be used to connect
auxiliary electrical equipment, such as a cellular
telephone.
The vehicle may have two accessory power outlets
located below the climate control system, or may have
one accessory power outlet and one cigarette lighter.
The cigarette lighter is designed to fit only in the
receptacle closest to the driver.
There may be another accessory power outlet in the
rear cargo area. If the vehicle has a floor console, there
is an accessory power outlet inside the storage bin and
one on the rear of the floor console.
To use an accessory power outlet, remove the
protective cap. When not in use, always cover the
accessory power outlet with the protective cap.
Notice:Leaving electrical equipment plugged in for
an extended period of time while the vehicle is off
will drain the battery. Power is always supplied to
the outlets. Always unplug electrical equipment
when not in use and do not plug in equipment that
exceeds the maximum 20 ampere rating. Certain power accessory plugs may not be compatible
to the accessory power outlet and could result in blown
vehicle or adapter fuses. If you experience a problem,
see your dealer for additional information on the
accessory power plugs.
The accessory power outlets are powered, even when
the ignition is in LOCK/OFF. Continuing to use power
outlets while the ignition is in LOCK/OFF may cause the
vehicle's battery to run down.
Notice:
Adding any electrical equipment to the
vehicle can damage it or keep other components
from working as they should. The repairs would not
be covered by the vehicle warranty. Do not use
equipment exceeding maximum amperage rating of
20 amperes. Check with your dealer before adding
electrical equipment.
When adding electrical equipment, be sure to follow the
proper installation instructions included with the
equipment.
Notice: Improper use of the power outlet can cause
damage not covered by the vehicle warranty. Do not
hang any type of accessory or accessory bracket
from the plug because the power outlets are
designed for accessory power plugs only.

Ashtray(s) and Cigarette Lighter
The vehicle may have a front ashtray located near the
center of the instrument panel. Pull on the door to open
it. The ashtray may have a cigarette lighter.
Notice:If papers, pins, or other flammable items are
put in the ashtray, hot cigarettes or other smoking
materials could ignite them and possibly damage
the vehicle. Never put flammable items in the
ashtray.
To remove the ashtray, open the door and pull the
ashtray bin toward you. To replace the ashtray, insert
the ashtray bin inside the ashtray door and press down
until it engages. To use the cigarette lighter, push it in
all the way, and let go. When it is ready for use, the
lighter pops back out.
Notice: Holding a cigarette lighter in while it is
heating does not let the lighter back away from the
heating element when it is hot. Damage from
overheating can occur to the lighter or heating
element, or a fuse could be blown. Do not hold a
cigarette lighter in while it is heating.

Loading Your Vehicle for Off-Road
Driving
{WARNING:
.Cargo on the load floor piled higher than the
seatbacks can be thrown forward during a
sudden stop. You or your passengers could
be injured. Keep cargo below the top of the
seatbacks.
.Unsecured cargo on the load floor can be
tossed about when driving over rough terrain.
You or your passengers can be struck by
flying objects. Secure the cargo properly.
.Heavy loads on the roof raise the vehicle's
center of gravity, making it more likely to roll
over. You can be seriously or fatally injured if
the vehicle rolls over. Put heavy loads inside
the cargo area, not on the roof. Keep cargo in
the cargo area as far forward and low as
possible.There are some important things to remember about
how to load your vehicle.
.The heaviest things should be on the floor, forward
of the rear axle. Put heavier items as far forward
as you can.
.Be sure the load is properly secured, so things are
not tossed around.
You will find other important information under Loading
the Vehicle
on page 5‑29and Tires on page 6‑64.
Environmental Concerns
Off-road driving can provide wholesome and satisfying
recreation. However, it also raises environmental
concerns. We recognize these concerns and urge every
off-roader to follow these basic rules for protecting the
environment:
.Always use established trails, roads, and areas
that have been specially set aside for public
off-road recreational driving and obey all posted
regulations.
.Avoid any driving practice that could damage
shrubs, flowers, trees, or grasses or disturb
wildlife. This includes wheel-spinning, breaking
down trees, or unnecessary driving through
streams or over soft ground.
.Always carry a litter bag and make sure all refuse
is removed from any campsite before leaving.

Heavy-DutyTrailer Wiring Harness
Package
For vehicles equipped with heavy duty trailering, the
harness is connected to a bracket on the hitch platform.
The seven-wire harness contains the following trailer
circuits:
.Yellow: Left Stop/Turn Signal
.Dark Green: Right Stop/Turn Signal
.Brown: Taillamps
.White: Ground
.Light Green: Back-up Lamps
.Red: Battery Feed*
.Dark Blue: Trailer Brake*
*The fuses for these two circuits are installed in the
underhood electrical center, but the wires are not
connected. They should be connected by your dealer or
a qualified service center. The fuse and wire for the
ITBC is factory installed and connected if the vehicle is
equipped with an ITBC. The fuse for the battery feed is
not required if the vehicle has an auxiliary battery. If the
vehicle does not have an auxiliary battery, have your
dealer or authorized service center install the
required fuse.
If charging a remote (non-vehicle) battery, press the
Tow/Haul mode button, if equipped, located at the end
of the shift lever. This will boost the vehicle system
voltage and properly charge the battery. If the trailer is
too light for Tow/Haul mode, or the vehicle is not
equipped with Tow/Haul, turn on the headlamps as a
second way to boost the vehicle system and charge the
battery.

Windshield Wiper Fuses
The windshield wiper motor is protected by an internal
circuit breaker and a fuse. If the motor overheats due to
heavy snow, etc., the wiper will stop until the motor
cools. If the overload is caused by some electrical
problem and not snow, etc., be sure to get it fixed.
Power Windows and Other Power
Options
Circuit breakers protect the power windows and other
power accessories. If the current load is too heavy, the
circuit breaker opens and then closes after a cool down
period, protecting the circuit until the problem is fixed or
goes away.
Fuses and Circuit Breakers
If the vehicle is a Two-mode Hybrid, see the Two-mode
Hybrid manual for more information.
The wiring circuits in the vehicle are protected from
short circuits by a combination of fuses, circuit breakers
and fusible thermal links. This greatly reduces the
chance of fires caused by electrical problems.
Look at the silver-colored band inside the fuse. If the
band is broken or melted, replace the fuse. Be sure you
replace a bad fuse with a new one of the identical size
and rating.
If you ever have a problem on the road and don't have
a spare fuse, you can borrow one that has the
same amperage. Just pick some feature of your vehicle
that you can get along without –like the radio or
cigarette lighter –and use its fuse, if it is the
correct amperage. Replace it as soon as you can.
