If the vehicle is left running it will automatically shut off
after 10 minutes unless a time extension has been done.
To manually shut off a remote start:
Aim the RKE transmitter at the vehicle and press
the remote start button until the parking lamps
turn off.
Turn on the hazard warning ashers.
Turn the ignition switch on and then off.
The remote vehicle start feature provides two separate
starts, each with 10 minutes of engine running, or it
provides one start with 10 minutes of engine running that
may be extended 10 more minutes. If you press and
release the transmitter lock button and then press and
hold the remote start button on the RKE transmitter again
before the rst 10 minutes of engine running time has
expired, 10 minutes are added to the remaining minutes.
For example, if the lock button and then the remote start
buttons are pressed again after ve minutes of the engine
run time, 10 minutes are added and you now have
15 minutes of engine running. The added ten minutes are
considered a second remote vehicle start.
Once two remote starts or a single start with a time
extension have been used, the vehicle must be started
with the ignition key before you can use the remote
start feature again.The remote vehicle start feature will not operate if the
key is in the ignition, the hood is not closed, or if there is
an emission control system malfunction.
The engine will turn off during a remote vehicle start if
the coolant temperature gets too high, or the oil pressure
is too low.
Your vehicle was shipped from the factory with the
remote vehicle start system enabled. The system may
be disabled through the Driver Information Center (DIC).

Doors and Locks
Door Locks
{CAUTION:
Unlocked doors can be dangerous.
Passengers, especially children, can easily
open the doors and fall out of a moving
vehicle. When a door is locked, the handle
will not open it. You increase the chance
of being thrown out of the vehicle in a
crash if the doors are not locked. So, wear
safety belts properly and lock the doors
whenever you drive.
Young children who get into unlocked
vehicles may be unable to get out. A child
can be overcome by extreme heat and can
suffer permanent injuries or even death
from heat stroke. Always lock your vehicle
whenever you leave it.
Outsiders can easily enter through an
unlocked door when you slow down or
stop your vehicle. Locking your doors can
help prevent this from happening.There are several ways to lock and unlock your vehicle.
Because your vehicle has the theft-deterrent system,
you must unlock the doors with the key or remote
keyless entry transmitter to avoid setting off the alarm.
From the outside, use either the key or the remote
keyless entry transmitter.
From the inside, use the power door lock switches or
manual lock knobs. The manual lock knobs are located
at the top of the door panel near the window.
Push the manual lock knob down to lock the door.
To unlock the door, pull up on the knob.

PASS-Key®III+ Electronic
Immobilizer Operation
Your vehicle has 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.
The system is automatically disarmed when the key is
turned to ON/RUN, ACC/ACCESSORY or START
from the LOCK/OFF position.
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.
If the engine does not start and the security light comes
on when trying to start the vehicle, 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 undamaged, try another ignition key. At this time,
you may also want to check the fuse, seeFuses
and Circuit Breakers on page 5-101. 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/retailer who can service the
PASS-Key
®III+ to have a new key made. In an
emergency, contact Roadside Assistance.
It is possible for the PASS-Key
®III+ decoder to “learn”
the transponder value of a new or replacement key. Up to
nine additional 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.
See your dealer/retailer 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.
2-21

To program the new key:
1. Verify that the new key has a
1stamped on it.
2. Insert the original, already programmed, key in the
ignition and start the engine. If the engine will not
start, see your dealer/retailer for service.
3. After the engine has started, turn the key to
LOCK/OFF, and remove the key.
4. Insert the new key to be programmed and turn it to
the ON/RUN position within ve seconds of
removing the original key.
The security light will turn off once the key has
been programmed.
5. Repeat Steps 1 through 4 if additional keys are to
be programmed.
If you lose or damage your PASS-Key
®III+ key, see
your dealer/retailer or a locksmith who can service
PASS-Key
®III+ to have a new key made.
Do not leave the key or device that disarms or
deactivates the theft deterrent system in the vehicle.
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 the 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. SeeTowing
a Trailer on page 4-27for the trailer towing
capabilities of your vehicle and more
information.
Following break-in, engine speed and load can be
gradually increased.

Ignition Positions
With the ignition key in the ignition, the key can be
turned to four different positions:
In order to shift out of PARK (P), ignition must be in the
ON/RUN or ACC/ACCESSORY and the regular brake
pedal must be applied.
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 (LOCK/OFF):This is the only position in which the
ignition key can be inserted or removed. This position
locks the ignition and transmission and steering column.
It is a theft-deterrent feature.
If the steering wheel is locked, move it from right to left
and turn the key to ACC/ACCESSORY. If none of
this works, then your vehicle needs service.
B (ACC/ACCESSORY):This position lets the radio
and windshield wipers operate while the engine is off.
To use ACC/ACCESSORY, turn the key clockwise.
C (ON/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
ACC/ACCESSORY or ON/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
LOCK/OFF, ACC/ACCESSORY and the key is in the
ignition. SeeDIC Warnings and Messages on page 3-75
for more information.
