2-10 Resynchronization
Pressing the transmitter buttons numerous times
(approximately 250 times) out of the vehicle's operating
range may cause the transmitter not to work. Replacing
the battery and pressing the transmitter buttons out
of range will also cause the transmitter not to work.
If only the fuel door button works, the transmitter needs
to be resynchronized to the receiver. Do this by pressing
and holding both the lock and unlock buttons on the
transmitter for about eight seconds. You must be within
range of the vehicle.
Once the transmitter has been resynchronized, the horn
will sound and the exterior lamps will flash once. The
system should now operate properly. See your dealer for
service if your transmitter still doesn't work properly.
Trunk
CAUTION:
It can be dangerous to drive with the trunk lid
open because carbon monoxide (CO) gas can
come into your vehicle. You can't see or smell
CO. It can cause unconsciousness and even death.
If you must drive with the trunk lid open or if
electrical wiring or other cable connections must
pass through the seal between the body and the
trunk lid:

Make sure all other windows are shut.

Turn the fan on your heating or cooling
system to its highest speed with the setting
on AUTO and the temperature between
65F (18C) and 85F (29C). That will
force outside air into your vehicle.
See ªComfort Controlsº in the Index.

If you have air outlets on or under the
instrument panel, open them all the way.
See ªEngine Exhaustº in the Index.

Theft-Deterrent System
If the ignition is off and
any door is open, the
SECURITY light will
flash, reminding you to
arm the system.
To arm the system, do the following:
1. Open the door.
2. Lock the door using the power door lock switch with
the door open or the Remote Keyless Entry (RKE)
system. The SECURITY light should come on and
stay on.
3. Close all the doors. The SECURITY light should
go off within approximately 30 seconds.
When the theft system activates, the horn will sound and
the lamps will flash for about 30 seconds when the door
or trunk is opened without the key or RKE system.Remember, the theft
-deterrent system won't arm if you
lock the doors with a key or use the manual door lock.
It activates only if you use a power door lock with the
door open or the RKE system.
To avoid activating the alarm by accident:

The vehicle should be locked with the door key or
the manual door lock after the doors are closed if
you don't want to arm the theft
-deterrent system.

Always unlock a door with a key or use the RKE
system. (Pressing the unlock button on the RKE
transmitter disables the theft
-deterrent system.)
Unlocking a door any other way will activate the
alarm when a door or the trunk is opened.
If you activate the alarm by accident, unlock the driver's
door with your key. You can also turn off the alarm by
using the unlock button on the RKE system, or by
starting the car with a valid key.
Changes or modifications made to this system by
other than an authorized service facility could void
authorization to use the theft system.

2-15 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 ªFuses and Circuit Breakersº
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
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 enable these
features for use.
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.

2-16
PASS-Key
III
Your vehicle is equipped
with the PASS
-Key III
(Personalized Automotive
Security System)
theft
-deterrent system.
PASS
-Key III is a passive
theft
-deterrent system. This
means you don't have to do
anything different to arm or
disarm the system. It works
when you insert or remove
the key from the ignition.
Your PASS
-Key III system operates on a radio
frequency subject to Federal Communications
Commission (FCC) Rules and with Industry Canada.
This device complies with Part 15 of the FCC Rules.
Operation is subject to the following two conditions:
(1) this device may not cause harmful interference,
and (2) this device must accept any interference
received, including interference that may cause
undesired operation.This device complies with RSS
-210 of Industry Canada.
Operation is subject to the following two conditions:
(1) this device may not cause interference, and (2)
this device must accept any interference received,
including interference that may cause undesired
operation of the device.
Changes or modifications to this system by other than
an authorized service facility could void authorization to
use this equipment.
PASS
-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.
When trying to start the vehicle and the engine does not
start and the SECURITY light comes on, the key may
have a damaged transponder. Turn the ignition off and
try again.

2-17
If the engine 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 ªFuses and Circuit
Breakersº 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 PASS
-Key III
to have a new key made.
It is possible for the PASS
-Key III decoder to learn
the transponder value of a new or replacement key.
Up to ten additional keys may be programmed for the
vehicle. This procedure is for learning additional keys
only. If all the currently programmed keys are lost or
do not operate, you must see your dealer or locksmith
who can service PASS
-Key III to have keys made
and programmed to the system.
See your dealer or a locksmith who can service
PASS
-Key III to get a new blank key that is cut
exactly as a current black colored driver's key that
operates the system. Do not use the gray colored
valet key for this procedure.To program the new key:
1. Insert the current driver's key (black in color) in the
ignition and start the engine. If the engine will not
start, see your dealer for service.
2. After the engine has started, turn the key to OFF and
remove the key.
3. Insert the key to be programmed and turn it to RUN
within ten seconds of removing the previous key.
4. The SECURITY light will turn off once the key has
been programmed. It may not be apparent that the
SECURITY light went on due to how quickly the
key is programmed.
5. Repeat the Steps 1 through 4 if additional keys are
to be programmed.
If you are ever driving and the SECURITY light
comes on and stays on, you will be able to start your
engine if you turn it off. Your PASS-Key III system,
however, is not working properly and must be serviced
by your dealer. Your vehicle is not protected by the
PASS
-Key III system at this time.
If you lose or damage a PASS
-Key III key, see your
dealer or a locksmith who can service PASS
-Key III to
have a new key made.

2-18
New Vehicle ªBreak-Inº
NOTICE:
Your vehicle doesn't need an elaborate ªbreak-in.º
But it will perform better in the long run if you
follow these guidelines:

Don't drive at any one speed -- fast or
slow
-- for the first 500 miles (805 km).
Don't make full
-throttle starts.

Avoid making hard stops for the first 200 miles
(322 km) or so. During this time your new
brake linings aren't yet broken in. Hard
stops with new linings can mean premature
wear and earlier replacement. Follow this
breaking
-in guideline every time you get new
brake linings.

Don't tow a trailer during break
-in.
See ªTowing a Trailerº in the Index for
more information.
Ignition Positions
With the key in the ignition switch, you can turn the key
to four different positions:
OFF: This position lets
you turn off the engine
and remove the key.
This position also locks
the steering wheel
and transaxle.
NOTICE:
If your key seems stuck in OFF and you can't
turn it, be sure you are using the correct key;
if so, is it all the way in? Turn the key only with
your hand. Using a tool to force it could break
the key or the ignition switch. If none of this
works, then your vehicle needs service.

2-24
Also use this gear to rock your vehicle back and forth
to get out of snow, ice or sand without damaging your
transaxle. See ªIf You're Stuck in Sand, Mud, Ice or
Snowº in the Index for additional information.
NEUTRAL (N): In this position, the engine doesn't
connect with the wheels. To restart when you're already
moving, use NEUTRAL (N) only. Also use NEUTRAL (N)
when your vehicle is being towed.
CAUTION:
Shifting out of PARK (P) or NEUTRAL (N) while
your engine is ªracingº (running at high speed)
is dangerous. Unless your foot is firmly on the
brake pedal, your vehicle could move very
rapidly. You could lose control and hit people
or objects. Don't shift out of PARK (P) or
NEUTRAL (N) while your engine is racing.
OVERDRIVE (D): This position is for normal driving.
If you need more power for passing, and you're:

Going less than 35 mph (55 km/h), push the
accelerator pedal about halfway down.

Going about 35 mph (55 km/h) or more, push the
accelerator all the way down.
The transaxle will shift down to the next gear and
have more power.
NOTICE:
If your vehicle seems to start up rather slowly, or
if it doesn't seem to shift gears as you accelerate,
something may be wrong with a transaxle system
sensor. If you drive very far that way, your
vehicle can be damaged. So if this happens, have
your vehicle serviced right away. Until then, you
can use SECOND (2) when you are driving less
than 35 mph (55 km/h) and OVERDRIVE (D)
for higher speeds.

2-26 Performance Shift Display (STS Only)
When your vehicle detects a change in driving
conditions, it will automatically initiate the appropriate
performance shift mode. When this occurs, the gear
display on the instrument panel cluster will change to
indicate that the transmission has shifted to a different
gear. For example, the gear display on the cluster may
indicate D, 3, 2, or 1 even though the gearshift lever is
still in OVERDRIVE (D). Once the performance shift
mode ends, the gear display on the cluster will return to
matching the gearshift lever indication.
Parking Brake
Hold the regular brake
pedal down with your right
foot and push the parking
brake pedal down with your
left foot to set the parking
brake. If the ignition is on,
the BRAKE indicator light
should come on. If it
doesn't, you need to have
your vehicle serviced.If the parking brake has not been fully released and
you try to drive with the parking brake on, the BRAKE
indicator light comes on and stays on. See ªBrake
System Warning and Park Brake Indicator Lightº in the
Index for more information.
When you shift out of PARK (P) or NEUTRAL (N)
and the engine is on, the parking brake should release.
If it doesn't, you can manually release the parking brake.
CAUTION:
Always shift to PARK (P) before pulling the
manual release lever. If your hand or arm is in
the way of the pedal you could be hurt. The pedal
springs back quickly. Keep your hand and arm
away when you use the manual release lever.
Before releasing the manual parking brake, be sure to put
the vehicle in PARK (P) and turn the ignition to OFF.
