Radio Security Code
This radio is equipped with an anti-theft feature which
requires that a four digit code number be entered when-
ever the power supply is interrupted (such as a discon-
nected battery). The four digit code can be found on the
last page of this manual. Please remove this page from
the manual and store it in a safe place outside of the
vehicle.To enter the code, turn the key to the ON or ACC position
and press the ON/VOL control. The word CODE will
appear on the display. Enter your four digit code by
pressing the appropriate preset buttons in sequence. Your
radio is now ready for basic operation.
If an invalid code is entered into the radio, the radio will
allow two more attempts. After a third attempt of enter-
ing an invalid code, the radio will go into a lockup mode.
This is to prevent continuous attempts at entering the
wrong code until the right code is found.
Once a radio is in this lockup mode, it must be in a state
where battery is applied for approximately 30 minutes.
During this time, if the radio is on, the display will show
ªWAITº. After approximately 30 minutes, (radio on)
radio will display ªCODEº thereby again querying the
operator for the 4 digit anti-theft code.
Operating Instructions - Radio Mode
NOTE:
Power to operate the radio is supplied through
the ignition switch. It must be in the ON or ACC position
to operate the radio.

WARNING!
Unintended movement of a vehicle could injure
those in and near the vehicle. As with all vehicles,
you should never exit a vehicle while the engine is
running. Before exiting a vehicle, you should always
shift the vehicle into P (Park), remove the key from
the ignition, and apply the parking brake. Once the
key is removed from the ignition, the transmission
shift lever is locked in the P (Park) position, securing
the vehicle against unwanted movement. Further-
more, you should never leave children unattended
inside a vehicle.
The following indicators should be used to ensure that
you have engaged the transmission shift lever into the P
(Park) position:
²When shifting into P (Park), depress the button on the
shift lever and firmly move the lever all the way
forward until it stops.
²Look at the shift indicator window on the console to
ensure it is in the P (Park) position.
²When engaged in P (Park), you will not be able to
move the shifter rearward without depressing the shift
lever button.
CAUTION!
Before moving the shift lever out of P (Park), you
must turn the ignition from LOCK to ON so the
steering wheel and shift lever are released. Other-
wise, damage to the steering column or shifter could
result.
R (Reverse)
For moving the vehicle rearward. Always stop before
moving the lever to R (Reverse), except when rocking
the vehicle.
N (Neutral)
Engine may be started in this position.

Pay particular attention to the hoses nearest to high heat
sources such as the exhaust manifold. Inspect hose rout-
ing to be sure hoses do not touch any heat source or
moving component that may cause heat damage or
mechanical wear.
Insure nylon tubing in these areas has not melted or
collapsed. Inspect all hose connections such as clamps
and couplings to make sure they are secure and no leaks
are present. Components should be replaced immedi-
ately if there is any evidence of degradation that could
cause failure.
Brake System
In order to assure brake system performance, all brake
system components should be inspected periodically.
Refer to the appropriate ªMaintenance Scheduleº in
Section 8 for suggested service intervals.
WARNING!
Riding the brakes can lead to brake failure and
possibly an accident. Driving with your foot resting
or riding on the brake pedal can result in abnormally
high brake temperatures, excessive lining wear, and
possible brake damage. You wouldn't have your full
braking capacity in an emergency.
Brake and Power Steering System Hoses
When servicing the vehicle for scheduled maintenance,
inspect surface of hoses for evidence of heat and me-
chanical damage. Hard and brittle rubber, cracking, tears,
cuts, abrasion, and excessive swelling suggest deteriora-
tion of the rubber. Particular attention should be made to
examining those hose surfaces nearest to high heat
sources, such as the exhaust manifold.
Inspect all hose clamps and couplings to make sure they
are secure and no leaks are present.
NOTE:Inspection of brake hoses should be done
whenever the brake system is serviced and every engine
oil change.

provides insulation against high floor pan tempera-
tures. You or your passengers could be burned if the
carpet is not properly in place. Always put the carpet
back into the vehicle before driving.

1. Unsnap the front and rear floor carpets. A snap is
located on the outboard side of each front seat.
2. Remove the attachment cap from the front footwell
area on both the driver and passenger side. The cap is
removed by pulling it straight out.
3. Remove the front and rear floor carpets.
4. Remove the cargo floor and wheelhouse carpets.
NOTE:If your vehicle is equipped with an Add-A-
TrunkŸ it must be removed to be able to remove the cargo
floor and wheelhouse carpets. For Add-A-TrunkŸ removal
procedure, refer to ªStorageº in Section 3 of this manual.
Follow These Steps To Replace The Carpet:
1. Place the front floor carpets in the vehicle.
2. Attach the carpet to the studs in the footwell and press
on the attachment caps to secure the carpet.
3. Place rear floor carpet in vehicle and snap rear carpet
to front floor carpet.
4. Install wheelhouse carpet followed by the cargo floor
carpet.
5. Reinstall Add-A-TrunkŸ if so equipped.
Seat Belt Maintenance
Do not bleach, dye or clean the belts with chemical
solvents or abrasive cleaners. This will weaken the fabric.
Sun damage will also weaken the fabric.
If the belts need cleaning, use a mild soap solution or
lukewarm water. Do not remove the belts from the
vehicle to wash them.
Replace the belts if they appear frayed or worn or if the
buckles do not work properly.
