Testing the Alarm
1. From inside the vehicle, roll down the window, then
get out of the vehicle, keeping the door open.
2. From outside of the vehicle, with the door open,
lock the vehicle using the power door lock or the
RKE system and close the door. Wait 30 seconds
until the security lamp goes off.
3. Reach in and unlock the door using the manual
lock and open the door. The horn will sound and
the hazard lights will flash.
You can turn off the alarm by unlocking the driver’s door
with your key, using the unlock button on the RKE
transmitter or by starting the car with a valid key.
If the alarm does not sound when it should, check to
see if the horn works. The horn fuse may be blown.
To replace the fuse, see
Fuses and Circuit Breakers on
page 5-95
. If the fuse does not need to be replaced,
you may need to have your vehicle serviced.
To reduce the possibility of theft, always arm the
theft-deterrent system when leaving your vehicle.

2-22
PASS-Key
®
III+ Electronic
Immobilizer Operation
Your vehicle has PASS-Key
®
III+ (Personalized
Automotive Security System) theft-deterrent system.
PASS-Key
®
III+ is a passive theft-deterrent system.
The system is automatically armed when the key
is removed from the ignition.
The system is automatically disarmed when the key is
turned to ON/RUN, ACC/ACCESSORY or START
from the LOCK/OFF position.
You do not have to manually arm or disarm the system.
The security light will come on if there is a problem
with arming or disarming the theft-deterrent system.
When the PASS-Key
®
III+ system senses that someone
is using the wrong key, it prevents the vehicle from
starting. Anyone using a trial-and-error method to start
the vehicle will be discouraged because of the high
number of electrical key codes.
If the engine does not start and the security light comes
on when trying to start the vehicle, there may be a
problem with your theft-deterrent system. Turn the
ignition off and try again.
If the engine still does not start, and the key appears to
be undamaged, try another ignition key. At this time,
you may also want to check the fuse, see
Fuses
and Circuit Breakers on page 5-95
. If the engine still
does not start with the other key, your vehicle needs
service. If your vehicle does start, the first key may be
faulty. See your dealer/retailer who can service the
PASS-Key
®
III+ to have a new key made. In an
emergency, contact Roadside Assistance.
It is possible for the PASS-Key
®
III+ decoder to “learn”
the transponder value of a new or replacement key.
Up to 10 keys may be programmed for the vehicle.
The following procedure is for programming additional
keys only. If all the currently programmed keys are
lost or do not operate, you must see your dealer/retailer
or a locksmith who can service PASS-Key
®
III+ to
have keys made and programmed to the system.

Information for these features is on the pages following.
Turn and Lane-Change Signals
An arrow on the instrument
panel cluster and in the
outside rearview mirror
flashes in the direction of
the turn or lane change.
Move the lever all the way up or down to signal a
turn. The lever returns automatically when the turn is
complete. If you momentarily press and release the lever,
the turn signal will flash 3 times.
Raise or lower the lever until the arrow starts to flash to
signal a lane change. Hold it there until the lane change is
complete.
The lever returns to its starting position when it is
released.
If after signaling a turn or lane change the arrow
flashes rapidly or does not come on, a signal bulb
may be burned out.
Have the bulbs replaced. If the bulb is not burned out,
check the fuse. See

Engine Oil
Checking Engine Oil
It is a good idea to check the engine oil level at each
fuel fill. In order to get an accurate reading, the oil must
be warm and the vehicle must be on level ground.
The engine oil dipstick handle is a yellow loop. See
Engine Compartment Overview on page 5-12
for
the location of the engine oil dipstick.
1. Turn off the engine and give the oil several minutes
to drain back into the oil pan. If this is not done, the
oil dipstick might not show the actual level.
2. Pull out the dipstick and clean it with a paper towel
or cloth, then push it back in all the way. Remove it
again, keeping the tip down, and check the level.
5-13
Power Steering Fluid
The power steering fluid
reservoir is located next to
the underhood fuse block
on the passenger side of
the vehicle. See
Engine
Compartment Overview
on page 5-12
for more
information on location.
When to Check Power Steering Fluid
It is not necessary to regularly check power steering fluid
unless you suspect there is a leak in the system or
you hear an unusual noise. A fluid loss in this system
could indicate a problem. Have the system inspected
and repaired.
How to Check Power Steering Fluid
To check the power steering fluid:
1. Turn the key off and let the engine compartment
cool down.
2. Wipe the cap and the top of the reservoir clean.
3. Unscrew the cap and wipe the dipstick with a
clean rag.
4. Replace the cap and completely tighten it.
5. Remove the cap again and look at the fluid level on
the dipstick.
The level should be at the FULL COLD mark.
If necessary, add only enough fluid to bring the
level up to the mark.
What to Use
To determine what kind of fluid to use, see
Recommended Fluids and Lubricants on page 6-11
.
Always use the proper fluid.
Notice:
Use of the incorrect fluid may damage the
vehicle and the damages may not be covered by
the vehicle’s warranty. Always use the correct fluid
listed in
Recommended Fluids and Lubricants on
page 6-11
.
5-31
Battery
This vehicle has a maintenance free battery. When it is
time for a new battery, see your dealer/retailer for one
that has the replacement number shown on the original
battery’s label.
Warning:
Battery posts, terminals, and related
accessories contain lead and lead compounds,
chemicals known to the State of California to cause
cancer and reproductive harm. Wash hands after
handling.
The battery is located under the rear seat cushion. To
access the battery, see
Rear Underseat Fuse Block
on page 5-98
. Access to the battery is not necessary to
jump start the vehicle. See
Jump Starting on page 5-38
.
{
CAUTION:
A battery that is not properly vented can let
sulfuric acid fumes into the area under the rear
seat cushion. These fumes can damage the rear
seat safety belt systems. You might not be able to
see this damage and the safety belts might not
provide the protection needed in a crash. If a
replacement battery is ever needed, it must be
vented in the same manner as the original battery.
Always make sure that the vent hose is properly
reattached before reinstalling the seat cushion.
5-36
The vehicle has an airbag system. Before attempting to
add anything electrical to the vehicle, see
Servicing
Your Airbag-Equipped Vehicle on page 1-68
.
Headlamp Wiring
The headlamp wiring system has four individual fuses. 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 fixed.
Power Windows and Other Power
Options
Circuit breakers in the fuse block protect the power
windows and other power accessories. When the
current load is too heavy, the circuit breaker opens and
closes, protecting the circuit until the problem is fixed or
goes away.
Fuses and Circuit Breakers
The wiring circuits in the vehicle are protected from
short circuits by a combination of fuses and circuit
breakers. 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 the 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.
Underhood Fuse Block
The underhood fuse block is located on the passenger
side of the engine compartment. Remove the fuse cover
and secondary service cover to access the fuse block.
Notice:
Spilling liquid on any electrical components
on the vehicle may damage it. Always keep the
covers on any electrical component.

Rear Underseat Fuse Block
The rear fuse block is located under the rear seat on
the driver side. The rear seat cushion must be removed
to access the rear fuse block.
Removing the Rear Seat Cushion
Notice:
If you touch the exposed wires with the
metal on the seat cushion, you could cause a short
that could damage the battery and or wires. Avoid
contact between the rear seat and the fuse
center whenever you remove or reinstall the rear
seat. Do not remove covers from any of the covered
parts, and do not store anything under the seats.
To remove the rear seat cushion, do the following:
1. Pull up on the front of the cushion to release the
front hooks.
2. Pull the cushion up and out toward the front of the
vehicle.
To access the fuse block, pull out and lift up on the
cover latch, located at the end of the fuse block, near
the battery cable.
