Trailer Brake Control Wiring
Harness
The trailer brake control wiring
harness is located under the
instrument panel to the right of the
steering column. The wires are
taped to the harness that goes to
the courtesy light under the
instrument panel. The harness has
the following wires:
Red Wire: AUX B+
Black Wire: Ground
Light Blue Wire: Brake Signal
Dark Blue Wire: Trailer Brakes
Trailer Recommendations
Subtract the hitch loads from the
Cargo Weight Rating (CWR). CWR
is the maximum weight of the
load the vehicle can carry. It does
not include the weight of the people
inside, but you can gure about
150 lbs. (68 kg) for each passenger.
The total cargo load must not be
more than the vehicles CWR.
Weigh the vehicle with the trailer
attached, so the GVWR or GAWR
are not exceeded. If using a
weight-distributing hitch, weigh the
vehicle without the spring bars
in place.
The best performance is obtained
by correctly spreading out the weight
of the load and choosing the
correct hitch and trailer brakes.

Trailer on page 4-42.

Engine Overheating
The vehicle has an indicator to warn
of engine overheating.
A coolant temperature gage is
displayed on the instrument panel.
SeeEngine Coolant Temperature
Gage on page 3-29.
You may decide not to lift the hood
when this warning appears, but
instead get service help right away.
SeeRoadside Service on page 7-6.
If you do decide to lift the hood,
make sure the vehicle is parked on
a level surface.
Then check to see if the engine
cooling fans are running. If the
engine is overheating, both fans
should be running. If they are not, do
not continue to run the engine and
have the vehicle serviced.The air conditioning might stop
working if the engine is too hot.
This is normal and helps cool the
engine.
Notice:Engine damage from
running the engine without
coolant is not covered by the
warranty.
Notice:If the engine catches re
because of being driven with
no coolant, your vehicle can be
badly damaged. The costly
repairs would not be covered by
the vehicle warranty.
If Steam Is Coming From The
Engine Compartment
{CAUTION
Steam from an overheated engine
can burn you badly, even if you
just open the hood. Stay away
from the engine if you see or hear
steam coming from it. Just turn it
off and get everyone away from
the vehicle until it cools down.
Wait until there is no sign of
steam or coolant before you
open the hood.
If you keep driving when your
engine is overheated, the liquids
in it can catch re. You or others
could be badly burned. Stop your
engine if it overheats, and get
out of the vehicle until the engine
is cool.
Service and Appearance Care 5-27

Tire Pressure Monitor
Operation
This vehicle may have a Tire
Pressure Monitor System (TPMS).
The TPMS is designed to warn
the driver when a low tire pressure
condition exists. TPMS sensors
are mounted onto each tire and
wheel assembly on the vehicle,
excluding the spare tire. The TPMS
sensors monitor the air pressure
in the vehicle’s tires and transmit the
tire pressure readings to a receiver
located in the vehicle.
When a low tire pressure condition
is detected, the TPMS illuminates
the low tire pressure warning light
located on the instrument panel
cluster.At the same time, a Driver
Information Center (DIC) message
is displayed on the DIC display
screen. The low tire pressure
warning light and the DIC warning
message come on at each
ignition cycle until the tires are
inated to the correct ination
pressure. For additional information
and details about the DIC operation
and displays seeDIC Operation and
Displays on page 3-34andDIC
Warnings and Messages on
page 3-37.
The low tire pressure warning light
may come on in cool weather
when the vehicle is rst started, and
then turn off as you start to drive.
This could be an early indicator that
the air pressure in the tire(s) are
getting low and need to be inated
to the proper pressure.A Tire and Loading Information
label, attached to the vehicle, shows
the size of the vehicle’s original
equipment tires and the correct
ination pressure for the vehicle’s
tires when they are cold. See
Loading the Vehicle on page 4-35,
for an example of the Tire and
Loading Information label and its
location on the vehicle. Also see
Inflation - Tire Pressure on
page 5-51.
The vehicle’s TPMS can warn you
about a low tire pressure condition
but it does not replace normal
tire maintenance. SeeTire
Inspection and Rotation on
page 5-57andTires on page 5-44.
Notice:Liquid tire sealants
could damage the Tire Pressure
Monitor System (TPMS) sensors.
Sensor damage caused by using
a tire sealant is not covered
by your warranty. Do not use
liquid tire sealants.
5-54 Service and Appearance Care

Leather
A soft cloth dampened with water
can be used to remove dust.
If a more thorough cleaning is
necessary, a soft cloth dampened
with a mild soap solution can
be used. Allow the leather to dry
naturally. Do not use heat to
dry. Never use steam to clean
leather. Never use spot lifters or
spot removers on leather. Many
commercial leather cleaners
and coatings that are sold to
preserve and protect leather may
permanently change the appearance
and feel of the leather and are
not recommended. Do not use
silicone or wax-based products, or
those containing organic solvents to
clean the vehicle’s interior because
they can alter the appearance
by increasing the gloss in a
non-uniform manner. Never use
shoe polish on leather.
Instrument Panel, Vinyl,
and Other Plastic
Surfaces
A soft cloth dampened with water
may be used to remove dust.
If a more thorough cleaning is
necessary, a clean soft cloth
dampened with a mild soap solution
can be used to gently remove
dust and dirt. Never use spot lifters
or removers on plastic surfaces.
Many commercial cleaners
and coatings that are sold to
preserve and protect soft plastic
surfaces may permanently change
the appearance and feel of the
interior and are not recommended.
Do not use silicone or wax-based
products, or those containing
organic solvents to clean the
vehicle’s interior because they can
alter the appearance by increasing
the gloss in a non-uniform manner.Some commercial products may
increase gloss on the instrument
panel. The increase in gloss
may cause annoying reections in
the windshield and even make
it difficult to see through the
windshield under certain conditions.
Care of Safety Belts
Keep belts clean and dry.
{CAUTION
Do not bleach or dye safety belts.
It may severely weaken them.
In a crash, they might not be able
to provide adequate protection.
Clean safety belts only with mild
soap and lukewarm water.
Service and Appearance Care 5-85

Chemical Paint Spotting
Some weather and atmospheric
conditions can create a chemical
fallout. Airborne pollutants can
fall upon and attack painted surfaces
on the vehicle. This damage can
take two forms: blotchy, ring-shaped
discolorations, and small, irregular
dark spots etched into the paint
surface.
Although no defect in the paint job
causes this, we will repair, at no
charge to the owner, the surfaces
of new vehicles damaged by this
fallout condition within 12 months
or 12,000 miles (20 000 km) of
purchase, whichever occurs rst.
Vehicle Identication
Vehicle Identication
Number (VIN)
This is the legal identier for your
vehicle. It appears on a plate in
the front corner of the instrument
panel, on the driver side. It can
be seen through the windshield from
outside the vehicle. The VIN also
appears on the Vehicle Certication
and Service Parts labels and the
certicates of title and registration.
Engine Identication
The eighth character in the VIN
is the engine code. This code helps
identify the vehicle’s engine,
specications, and replacement
parts. See “Engine Specications”
underCapacities and Specifications
on page 5-96for your vehicle’s
engine code.
Service Parts
Identication Label

glove box. It is very helpful if
you ever need to order parts.
The label has the following
information:
Vehicle Identication
Number (VIN)
Model designation
Paint information
Production options and special
equipment
Do not remove this label from the
vehicle.
