PASS-Key
®
III+ Electronic
Immobilizer Operation
Your vehicle is equipped with 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.
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.
When trying to start the vehicle if the engine does not
start and the security light on the instrument panel
cluster comes on, 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 not damaged, try another ignition key. At this time,
you may also want to check the fuse, see
Fuses and
Circuit Breakers on page 5-98
. 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. See
Roadside
Assistance Program on page 7-7
.
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.

Flash-To-Pass Feature.
Information for these features is on the pages following.
Turn and Lane-Change Signals
An arrow on the instrument
panel cluster flashes in the
direction of the turn or
lane change.
You may also have an arrow in the outside mirror that
flashes when the turn signal is used. See
Outside Power
Mirrors on page 2-36
for more information.
Move the lever all the way up or down to signal a turn.
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. If you momentarily press and
release the lever, the turn signal will flash three times.
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
Fuses and Circuit Breakers on
page 5-98

Inadvertent Power Battery Saver
This feature is designed to protect your vehicle’s battery
against drainage from the interior lamps, or garage
door opener. When the ignition is turned off, the power
to these features will automatically turn off after
10 minutes. Power will be restored for an additional
10 minutes if any door is opened, the trunk is opened or
the courtesy lamp switch is turned on.
Battery Run-Down Protection
This feature helps prevent the battery from being drained,
if the interior courtesy lamps, reading/map lamps, visor
vanity lamps or trunk lamp are accidentally left on. If any
of these lamps are left on, they automatically turn off after
10 minutes, if the ignition is off. The lamps will not come
back on again until one of the following occurs:
The ignition is turned on.
The exterior lamps control is turned off, then on again.
The headlamps will timeout after 10 minutes, if they are
manually turned on with the ignition on or off.
Accessory Power Outlet(s)
The accessory power outlets can be used to plug in
electrical equipment, such as a cellular telephone.
The vehicle may have up to three power outlets
depending on the type of front seat installed. If the
vehicle has front bucket seats with a center console,
there are two outlets inside the rear storage
compartment. An extra power outlet can be found under
the climate control system next to the ashtray.
The vehicle may have a small cap that must be pulled
down to access the accessory power outlet. Cover the
outlet with the protective cap when it is not being used.
Notice:
Leaving electrical equipment on for
extended periods will drain the battery. Always turn
off electrical equipment when not in use and do
not plug in equipment that exceeds the maximum
amperage rating.
Certain electrical accessories may not be compatible to
the accessory power outlets and could result in blown
vehicle or adapter fuses. If you experience a problem
see your dealer/retailer for additional information on the
accessory power outlets.

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 5-14
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.
5-17
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 “Removing the Rear Seat
Cushion” under
Rear Underseat Fuse Block on
page 5-101
. Access to the battery is not necessary to
jump start the vehicle. See
Jump Starting on page 5-44
.
{
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
CAUTION:
(Continued)
CAUTION:
(Continued)
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.
To be sure the vent hose (A) is properly attached, the
vent hose connectors (B) must be securely reattached to
the vent outlets (C) on each side of the battery and the
vent assembly grommet (D) must be secured to the
floor pan (E).

Electrical System
Add-On Electrical Equipment
Notice:
Do not add anything electrical to the
vehicle unless you check with your dealer/retailer
first. Some electrical equipment can damage
the vehicle and the damage would not be covered
by the vehicle’s warranty. Some add-on electrical
equipment can keep other components from
working as they should.
Add-on equipment can drain the vehicle battery, even if
the vehicle is not operating.
The vehicle has an airbag system. Before attempting to
add anything electrical to the vehicle, see
Servicing
Your Airbag-Equipped Vehicle on page 1-76
.
Power Windows and Other Power
Options
Circuit breakers in the rear 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 your 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.
You will find a fuse puller clipped in both of the fuse
blocks. Snap the wide end of the fuse puller at the side
indentations and pull the fuse out.
The MaxiFuses 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 MaxiFuse should blow, have your vehicle
serviced by your dealer/retailer immediately.
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.
