111

PASS-Key®III+ 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. This means you do
not have to do anything special to arm or disarm
the system. It works when you insert or remove the
key from the ignition.
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, the key may have a
damaged transponder. 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, seeFuses and Circuit Breakers on page 428.
If the engine still does not start with the other key,
your vehicle needs service. If your vehicle does
start, the rst key may be faulty. See your dealer
who can service the PASS-Key
®III+ to have a new
key made. In an emergency, contact Roadside
Assistance. SeeRoadside Assistance Program
on page 466.
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 or a
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 key blank that is cut
exactly as the ignition key that operates the system.
112

To program the new key do the following:
1. Verify that the new key has a
1stamped on it.
2. Insert the already programmed key in the
ignition and start the engine. If the engine
will not start, see your dealer for service.
3. After the engine has started, turn the key to
OFF, and remove the key.
4. Insert the key to be programmed and turn it to
the RUN position within ve seconds of the
original key being turned to the OFF position.
5. The security light will turn off once the key has
been programmed.
6. Repeat Steps 1 through 5 if additional keys
are to be programmed.
If you are ever driving and the security light comes
on and stays on, you may be able to restart 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 your PASS-Key
®III+ key,
see your dealer or a locksmith who can service
PASS-Key
®III+ to have a new key made.
Starting and Operating Your
Vehicle
New Vehicle Break-In
Notice:Your vehicle does not need an
elaborate break-in. But it will perform better in
the long run if you follow these guidelines:
Do not drive at any one constant speed, fast
or slow, for the rst 500 miles (805 km).
Do not make full-throttle starts. Avoid
downshifting to brake, or slow, the vehicle.
Avoid making hard stops for the rst
200 miles (322 km) or so. During this time
your new brake linings are not 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.
Do not tow a trailer during break-in. See
Towing a Trailer on page 315for the trailer
towing capabilities of your vehicle and more
information.
Following break-in, engine speed and load can
be gradually increased.
113

Ignition Positions
With the ignition key in the ignition, the key can be
turned to four different positions:
Notice:Using a tool to force the key from the
ignition switch could cause damage or break
the key. Use the correct key and turn the key
only with your hand. Make sure the key is in all
the way. If none of this works, then your vehicle
needs service.A (OFF):This is the only position in which the
ignition key can be inserted or removed. This
position locks the ignition and transaxle. It is a
theft-deterrent feature.
B (ACCESSORY):This position lets the radio
and windshield wipers operate while the engine is
off. To use ACCESSORY, turn the key clockwise.
C (RUN):This position is where the key returns
to after the vehicle is started. This position displays
some of the warning and indicator lights.
The battery could be drained if you leave the key in
the ACCESSORY or RUN position with the engine
off. You may not be able to start your vehicle if the
battery is allowed to drain for an extended period
of time.
D (START):This position starts the engine.
A warning chime will sound and the Driver
Information Center (DIC) will display DRIVER
DOOR OPEN when the driver’s door is opened if
the ignition is in OFF, ACCESSORY and the key is
in the ignition. SeeDIC Warnings and Messages on
page 221for more information.
114

Parking Brake
The parking brake pedal
is located to the left of
the regular brake pedal,
near the driver’s door.
To set the parking brake, hold the regular brake
pedal down with your right foot and push the
parking brake pedal down with your left foot.
If the ignition is on, the brake system warning light
on the instrument panel cluster should come
on. If it does not, you need to have your vehicle
serviced.A warning chime will sound if the parking brake is
set, the ignition is on, and the vehicle speed is
greater than 5 mph (8 km/h). The brake light will
come on and stay on until the parking brake is
released. SeeBrake System Warning Light on
page 201for more information.
To release the parking brake, hold the regular
brake pedal down with your right foot and push
the parking brake pedal down with your left
foot. When you lift your left foot, the parking
brake pedal will follow it to the released position.
Notice:Driving with the parking brake on
can overheat the brake system and cause
premature wear or damage to brake system
parts. Verify that the parking brake is fully
released and the brake warning light is
off before driving.
If you are towing a trailer and are parking on any
hill, seeTowing a Trailer on page 315.
122

Torque Lock
If you are parking on a hill and you do not shift your
transaxle into PARK (P) properly, the weight of the
vehicle may put too much force on the parking pawl
in the transaxle. You may nd it difficult to pull the
shift lever out of PARK (P). This is called torque
lock. To prevent torque lock, set the parking brake
and then shift into PARK (P) properly before you
leave the driver’s seat. To nd out how, seeShifting
Into Park (P) on page 123.
If torque lock does occur, you may need to
have another vehicle push yours a little uphill to
take some of the pressure from the parking pawl in
the transaxle, so you can pull the shift lever out
of PARK (P).
Shifting Out of Park (P)
Your vehicle has an automatic transaxle shift lock
control system. You have to fully apply your regular
brakes before you can shift from PARK (P) when
the ignition is RUN. SeeAutomatic Transaxle
Operation on page 119.
The shift lock control system is designed to do the
following:
Prevent the ignition key from being removed
unless the shift lever is in PARK (P).
Prevent movement of the console shift lever
out of PARK (P) unless the ignition is in a
position other than OFF.
The shift lock control system is always functional
except in the case of a dead battery or low
voltage (less than 9 V) battery.
If you cannot shift out of PARK (P), ease the
pressure on the shift lever. Push the shift lever
all the way into PARK (P) as you maintain
brake application. Then move the shift lever into
the gear you want.
If you are still having a problem shifting, then have
your vehicle serviced soon.
