Trunk
{CAUTION:
It can be dangerous to drive with the trunk lid
open because carbon monoxide (CO) gas can
come into your vehicle. You can not see or
smell CO. It can cause unconsciousness and
even death. If you must drive with the trunk lid
open or if electrical wiring or other cable
connections must pass through the seal
between the body and the trunk lid:
Make sure all other windows are shut.
Turn the fan on your heating or cooling
system to its highest speed and select the
control setting that will force outside air
into your vehicle. See Climate Control
System in the Index.
If you have air outlets on or under the
instrument panel, open them all the way.
SeeEngine Exhaust on page 2-37.
Trunk Lock Release
The trunk lock release
button is located to the left
of the steering wheel on
the instrument panel.
Press the button to open the trunk. To use this feature,
your vehicle must be in PARK (P) or NEUTRAL (N)
and the valet lockout switch must be off.
You can also press the button with the trunk symbol on
the remote keyless entry transmitter to open the
trunk. To disable this feature, see “Valet Lockout Switch”
underTheft-Deterrent Systems on page 2-19.

Air Bag Readiness Light
There is an air bag readiness light on the instrument
panel, which shows AIR BAG or the air bag symbol. The
system checks the air bag’s electrical system for
malfunctions. The light tells you if there is an electrical
problem. The system check includes the air bag sensors,
the air bag modules, the wiring and the crash sensing and
diagnostic module. For more information on the air bag
system, seeAir Bag Systems on page 1-50.
This light will come on when you start your vehicle, and
it will ash for a few seconds. Then the light should
go out. This means the system is ready.If the air bag readiness light stays on after you start the
vehicle or comes on when you are driving, your air
bag system may not work properly. Have your vehicle
serviced right away.
{CAUTION:
If the air bag readiness light stays on after you
start your vehicle, it means the air bag system
may not be working properly. The air bags in
your vehicle may not inate in a crash, or they
could even inate without a crash. To help avoid
injury to yourself or others, have your vehicle
serviced right away if the air bag readiness light
stays on after you start your vehicle.
The air bag readiness light should ash for a few
seconds when you turn the ignition key to ON. If the
light does not come on then, have it xed so it will
be ready to warn you if there is a problem. United States

Turn Signals When Towing a Trailer
When you tow a trailer, your vehicle may need a
different turn signal asher and/or extra wiring. Check
with your dealer. The arrows on your instrument
panel will ash whenever you signal a turn or lane
change. Properly hooked up, the trailer lamps will also
ash, telling other drivers you are about to turn,
change lanes or stop.
When towing a trailer, the arrows on your instrument
panel will ash for turns even if the bulbs on the trailer
are burned out. Thus, you may think drivers behind
you are seeing your signal when they are not. It
is important to check occasionally to be sure the trailer
bulbs are still working.
Driving on Grades
Reduce speed and shift to a lower gearbeforeyou start
down a long or steep downgrade. If you do not shift
down, you might have to use your brakes so much that
they would get hot and no longer work well.
On long uphill grades, reduce speed to 45 to 50 mph
(70 to 90 km/h) and avoid prolonged use of SECOND (2)
gear and engine speeds above 3800 rpm.
Climbing grades steeper than four percent at
temperatures above 90° F (32° C) with a loaded vehicle
and trailer is not recommended. The cooling system
may temporarily overheat. SeeEngine Overheating on
page 5-31.
Parking on Hills
{CAUTION:
You really should not park your vehicle, with a
trailer attached, on a hill. If something goes
wrong, your rig could start to move. People
can be injured, and both your vehicle and the
trailer can be damaged.
But if you ever have to park your rig on a hill, here is
how to do it:
1. Apply your regular brakes, but do not shift into
PARK (P).
2. Have someone place chocks behind the trailer
wheels.
3. When the wheel chocks are in place, release the
regular brakes until the chocks absorb the load.
4. Reapply the regular brakes. Then shift into
PARK (P) rmly and apply your parking brake.
5. Release the regular brakes.

Electrical System
Add-On Electrical Equipment
Notice:Don’t add anything electrical to your vehicle
unless you check with your dealer rst. Some
electrical equipment can damage your vehicle and
the damage wouldn’t be covered by your warranty.
Some add-on electrical equipment can keep other
components from working as they should.
Your vehicle has an air bag system. Before attempting
to add anything electrical to your vehicle, see
Servicing Your Air Bag-Equipped Vehicle on page 1-60.
Headlamp Wiring
The headlamp wiring system has four individual fuses,
LF low, RF low, LF high and RF high. An electrical
overload will cause the lamps to go on and off, or in
some cases to remain off. If this happens, have
the headlamp wiring checked right away.
Windshield Wiper Fuses
The windshield wiper motor is protected by an internal
circuit breaker. If the wiper motor overheats due to
heavy snow, the wipers will stop until the motor cools
and will then restart.
A fuse powers the wiper motor. If the fuse blows, there
is an electrical problem. Be sure to have it xed.
Power Windows and Other Power
Options
Circuit breakers protect the power windows and power
seats. When the current load is too heavy, the circuit
breaker opens and closes, protecting the circuit until the
problem is xed or goes away.
5-107

Fuses and Circuit Breakers
The wiring circuits in your vehicle are protected from
short circuits by a combination of fuses and circuit
breakers. This greatly reduces the chance of res
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 a fuse should blow, see your dealer
for service immediately.
If you ever have a problem on the road and do not have
a spare fuse, you can “borrow” one that has the same
amperage. 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.
The fuses are located in two fuse blocks, one located in
the engine compartment on the passenger’s side and
the other under the rear seat on the driver’s side.
If a fuse should blow, have your vehicle serviced by
your dealer immediately.
Underhood Fuse Block
The underhood fuse block
is located next to the
engine on the passenger’s
side of the vehicle. For
more information on
location, seeEngine
Compartment Overview on
page 5-14.
To access the fuses, push in the two tabs located at
each end of the fuse block cover. Then lift the cover off.
Fuse 22 or 23 can be moved to the outer position to
enable the accessory power outlets or cigarette lighter
when the ignition is not on. See your dealer for
additional assistance, if needed.
