Lockout Protection
Lockout protection is a standard feature intended to
provide enhanced security and convenience. This
feature prevents a driver who has left the keys in the
ignition from locking the doors or using the power door
locks while any door is open.
To override this feature, when the key is in the ignition
and a door is open, hold the power door lock switch
for three seconds.
This feature cannot guarantee that you will never be
locked out of your vehicle. If you don’t leave the keys in
the ignition, or if you use the manual door lock, or if you
use the remote keyless entry transmitter (if equipped),
you could still lock your keys inside your vehicle. Always
remember to take your keys with you.
Trunk
To unlock the trunk from the outside, insert the key and
turn the trunk lock cylinder or use the remote keyless
entry transmitter.
When closing the trunk, push the trunk lid in the center
to ensure that the lock fully latches.
{CAUTION:
It can be dangerous to drive with the trunk lid
open because carbon monoxide (CO) gas can
come into your vehicle. You cannot 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 2-26.

Safety Belt Reminder Light
When the key is turned to ON or START, a chime will
come on for several seconds to remind people to fasten
their safety belts, unless the driver’s safety belt is
already buckled.
The safety belt light will
also come on and stay on
for several seconds, then it
will flash for several more.
If the driver’s belt is already buckled, neither the chime
nor the light will come on.
Airbag Readiness Light
There is an airbag readiness light on the instrument
panel, which shows airbag. The system checks
the airbag’s electrical system for malfunctions. The light
tells you if there is an electrical problem. The system
check includes the airbag modules, the wiring and
the crash sensing and diagnostic module. For more
information on the airbag system, seeAirbag System on
page 1-51.
This light will come on when you start your vehicle, and
it will flash for a few seconds. Then the light should
go out. This means the system is ready.

Turn Signals When Towing a Trailer
When you tow a trailer, your vehicle may need a
different turn signal flasher and/or extra wiring. Check
with your dealer. The arrows on your instrument
panel will flash whenever you signal a turn or lane
change. Properly hooked up, the trailer lamps will also
flash, telling other drivers you are about to turn,
change lanes or stop.
When towing a trailer, the arrows on your instrument
panel will flash 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.
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) yet. When parking uphill, turn your
wheels away from the curb. When parking downhill,
turn your wheels into the curb.
2. Have someone place chocks under the trailer
wheels.
3. When the chocks are in place, release the regular
brakes until the chocks absorb the load.
4. Reapply the regular brakes. Then apply your
parking brake and shift into PARK (P).
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 airbag system. Before attempting to
add anything electrical to your vehicle, seeServicing
Your Airbag-Equipped Vehicle on page 1-56.
Windshield Wiper Fuses
The windshield wiper motor is protected by a 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, have
it fixed.
Power Windows and Other Power
Options
A circuit breaker in the fuse panel protects the power
windows. When the current load is too heavy, the circuit
breaker opens and closes, protecting the circuit until
the problem is fixed.
Fuses and Circuit Breakers
The wiring circuits in your vehicle are protected from
short circuits by a combination of fuses, circuit breakers
and fusible links. This greatly reduces the chance of
damage 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 to
replace a bad fuse with a new one of the identical
size and rating.
There are three fuse blocks in your vehicle: two
instrument panel fuse blocks and the engine
compartment fuse block.
There are four spare fuses located in the driver’s side
instrument panel end cap for your use.
