The security system helps to protect
your vehicle and valuables from
theft. The horn sounds and a
combination of headlights, parking
lights, side marker lights, and
taillights flashes if someone attempts
to break into your vehicle or remove
the radio. This alarm continues for 2
minutes, then the system resets. To
reset an alarming system before the
2 minutes have elapsed, unlock the
driver's door with the key or the
remote transmitter.
The security system automatically
sets 15 seconds after you lock the
doors, hood, and the tailgate. For the
system to activate, you must lock the
doors and the tailgate from the
outside with the key, driver's lock
tab, door lock master switch, or
remote transmitter. The security
system indicator on the instrument
panel starts blinking immediately to
show you the system is setting itself.
Once the security system is set,
opening any door, the tailgate, or the
hood without using the key or the
remote transmitter, will cause the
alarm to activate. It will also activate
if the audio unit is removed from the
dashboard or the wiring is cut.The alarm will also be activated if a
passenger inside the locked vehicle
turns the ignition switch on.
The security system will not set if the
hood, tailgate, or any door is not fully
closed. Before you leave the vehicle,
make sure the doors, tailgate, and
hood are securely closed.
NOTE:
To see if the system is set
after you exit the vehicle, press the
LOCK button on the remote
transmitter within 5 seconds. If the
system is set, a beep will sound.
Do not attempt to alter this system or
add other devices to it.

Headlight Aiming
The headlights were properly aimed
when your vehicle was new. If you
regularly carry heavy items in the
cargo area or pull a trailer,
readjustment may be required.
Adjustments should be done by your
dealer or another qualified
technician.
Low Beam Headlight Bulb
Replacement
The low beam headlight bulbs are
high voltage discharge tube. High
voltage can remain in the circuit even
with the light switch off and the key
removed. Because of this, you should
not attempt to examine or change a
low beam headlight bulb yourself. If
a low beam headlight bulb fails, take
the vehicle to your dealer to have it
replaced.Replacing a High Beam Headlight
Bulb
Your vehicle has halogen headlight
bulbs. When replacing a bulb, handle
it by its base, and protect the glass
from contact with your skin or hard
objects. If you touch the glass, clean
it with denatured alcohol and a clean
cloth.
Halogen headlight bulbs get very hot
when lit. Oil, perspiration, or a scratch
on the glass can cause the bulb to
overheat and shatter.
1. Open the hood.
Remove the electrical connector
from the bulb by pushing on the
tab and pulling the connector
down.
2. Remove the bulb by turning it about one-quarter turn
counterclockwise.
3. Insert the new bulb into the hole,and turn it one-quarter turn
clockwise to lock it in place.
4. Push the electrical connector onto the new bulb.
5. Turn on the headlights to test the new bulb.

Diagnosing why the engine won't
start falls into two areas, depending
on what you hear when you turn the
ignition switch to the START (III)
position:●You hear nothing, or almost
nothing. The engine's starter
motor does not operate at all, or
operates very slowly.●You can hear the starter motor
operating normally, or the starter
motor sounds like it is spinning
faster than normal, but the engine
does not start up and run.Nothing Happens or the Starter
Motor Operates Very Slowly
When you turn the ignition switch to
the START (III) position, you do not
hear the normal noise of the engine
trying to start. You may hear a
clicking sound, a series of clicks, or
nothing at all.
Check these things:
●Check the transmission interlock.
The transmission must be in Park
or neutral or the starter will not
operate.●Turn the ignition switch to the ON
(II) position. Turn on the
headlights, and check their
brightness. If the headlights are
very dim or do not come on at all,
the battery is discharged. See
Jump Starting
on page 461.
●Turn the ignition switch to the
START (III) position. If the
headlights do not dim, check the
condition of the fuses. If the fuses
are OK, there is probably
something wrong with the
electrical circuit for the ignition
switch or starter motor. You will
need a qualified mechanic to
determine the problem (see
Emergency Towing on page 475).
If the headlights dim noticeably or go
out when you try to start the engine,
either the battery is discharged or
the connections are corroded. Check
the condition of the battery and
terminal connections (see page 450).
You can then try jump starting the
vehicle from a booster battery (see
page 461).

Checking and Replacing Fuses
If something electrical in your
vehicle stops working, the first thing
you should check for is a blown fuse.
Determine from the chart on pages
473 and 474, or the diagram on the
fuse box lid, which fuse or fuses
control that device. Check those
fuses first, but check all the fuses
before deciding that a blown fuse is
the cause. Replace any blown fuses,
and check if the device works.1. Turn the ignition switch to the LOCK (0) position. Make sure the
headlights and all other
accessories are off.
2. (Under-hood fuse boxes) Remove the cover from the fuse
box.
3. Check each of the large fuses inthe under-hood fuse box by
looking through the side window
at the wire inside. Remove the
screws with a Phillips-head
screwdriver.FUSE BLOWN
