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” in the
Index. 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.
Valet Lock
This switch is located inside the glove box on the
left
-
hand side. Pressing this switch to ON will disable
the use of the trunk, fuel door and garage door opener.
Pressing this switch to
OFF will make these
features reusable.
Locking the glove box with your key will also help to
secure your vehicle. Note that the RKE transmitter can’t
open the trunk or fuel door if the valet lock switch is in
the ON position.

Key III uses a radio frequency transponder in the
key that matches a decoder in your vehicle.
When the PASS
-
Key III system senses that someone is
using the wrong key, it shuts down the vehicle’s starter
and fuel systems. The starter will not work and fuel will
stop being delivered to the engine. Anyone using a
trial
-
and
-
error method to start the vehicle will be
discouraged because of the high number of electrical
key codes.
If when trying to start the vehicle, the engine does not
start and the STARTING DISABLED REMOVE KEY
message is displayed in the Driver Information Center,
your key should be checked for damage. 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” in the Index). 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 or a locksmith who can service the

If you are ever driving and the SERVICE THEFT

Turn Signal/Multifunction Lever
Turn and Lane Change Signals
To signal a turn, move the lever on the left side of the
steering wheel all the way up or down. The lever returns
automatically when the turn is complete.
An arrow on the instrument
panel will flash in the
direction of the turn or
lane change.
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 when it’s released.
If the turn signal is left on, a warning chime will sound
and the Driver Information Center (DIC) will display
TURN SIGNAL ON (after driving about a mile) to
remind you to turn it off.
Arrows that flash rapidly when signaling for a turn or
lane change may be caused by a burned
-
out signal bulb.
Other drivers won’t see the turn signal.
Replace burned
-
out bulbs to help avoid possible
accidents. Check the fuse (see “Fuses and Circuit
Breakers” in the Index) and check for burned
-
out bulbs
if the arrow fails to work when signaling a turn.
Headlamp High/Low Beam
When the low
-
beam headlamps are on, push the turn
signal lever away from you to change the headlamps to
high beam.
This light on the instrument
panel will be on, indicating
high
-
beam usage.
Pull the turn signal lever toward you to return to
low
-
beam headlamps.

Adding Coolant
If you need more coolant, add the proper DEX
-
COOL
R
coolant mixture
at the surge tank
, but only when the
engine is cool.
CAUTION:
You can be burned if you spill coolant on hot
engine parts. Coolant contains ethylene glycol,
and it will burn if the engine parts are hot
enough. Don’t spill coolant on a hot engine.
When replacing the pressure cap, make sure it is
hand
-
tight.
Power Steering Fluid
The power steering fluid
reservoir is located next to
the fuse relay center on the
passenger’s side of
the engine.
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.
yellow

6-27
How to Check Power Steering Fluid
When the engine compartment is cool, wipe the cap and
the top of the reservoir clean, then unscrew the cap and
wipe the dipstick with a clean rag. Replace the cap and
completely tighten it. Then 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” in the
Maintenance Schedule booklet. Always use the proper
fluid. Failure to use the proper fluid can cause leaks and
damage hoses and seals.
Windshield Washer Fluid
What to Use
When you need windshield washer fluid, be sure to read
the manufacturer’s instructions before use. If you will be
operating your vehicle in an area where the temperature
may fall below freezing, use a fluid that has sufficient
protection against freezing.
Adding Washer Fluid
When your vehicle’s windshield washer fluid level
becomes low, a CHECK WASHER FLUID message will
appear on the Driver Information Center (DIC). You will
need to add fluid soon.
The windshield washer fluid reservoir is located next to
the fuse relay center on the passenger’s side of
the engine.
Open the cap labeled WASHER FLUID. Add washer
fluid until the tank is full.

Electrical System
Add-On Electrical Equipment
NOTICE:
Don’t add anything electrical to your vehicle
unless you check with your dealer first. 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” in the Index.
Headlamp Wiring
The headlamp wiring has an individual fuse. 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
A circuit breaker protects the wiper motor. If the wiper
motor overheats due to heavy snow, the wipers will stop
until the motor cools and will then restart.
A MaxiFuse
R
powers the wiper motor. If the MaxiFuse
blows, there is an electrical problem. Be sure to have
it fixed.
Power Windows and Other Power Options
Circuit breakers protect the power windows. When the
current load is too heavy, the circuit breaker opens and
closes, protecting the circuit until the problem is fixed or
goes away.
yellow

6-60
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. If a MaxiFuse should blow, see your dealer
for service immediately.
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. 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 MaxiFuses are located in two Bussed Electrical
Centers (BEC), one located near 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 immediately.
Underhood Junction Block
The front Bussed Electrical Center (BEC) is located in
the front of the engine compartment between the
windshield washer fluid reservoir and the power steering
fluid reservoir (on the passenger’s side). Lift the cover
to gain access.

Removing the Rear Seat Cushion
NOTICE:
The battery and main fuse boxes are located
under the rear seat cushion. The battery’s ground
terminal and some relay wires are exposed. To
help avoid damage to the battery and wires, be
careful when removing or reinstalling the seat
cushion. Do not remove covers from covered
parts. Do not store anything under the seat, as
objects could touch exposed wires and cause a
short.
To Remove the Rear Seat Cushion
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.
