Operation
You can lock and unlock the vehicle’s doors and the
liftgate from about 3 feet (1 m) up to 30 feet (9 m) away
using the remote keyless entry transmitter supplied

section for more detailed information.
"(Unlock):When you press unlock on the remote
keyless entry transmitter, only the driver’s door
will unlock. If you press unlock again within ve seconds,
all the doors and the liftgate will unlock. If you would
like all the doors to unlock the rst time you press
unlock, see “FOB UNLOCK ON 1ST PRESS” underDIC
Vehicle Personalization (Uplevel Only) on page 3-68.
If your vehicle has the content theft-deterrent system,

Remote Vehicle Start
This feature allows you to start the engine from outside
the vehicle.
Laws in some local communities may restrict the use of
remote starters. For example, some laws may require
a person using remote start to have the vehicle in view
when doing so. Check local regulations for any
requirements on remote starting of vehicles.
/(Remote Vehicle Start):If your vehicle has the
remote vehicle start feature, the remote keyless entry
transmitter will have a button with this symbol on it.
An increased range of operation is provided with the
remote keyless entry transmitter that has the remote
vehicle start button. The vehicle can be started from
approximately 180 feet (60 m) away. However, the
operating range may be less while the engine is running
and you will need to be closer to your vehicle to turn
it off than you were to turn it on.
Do not use the remote start feature if your vehicle is
low on fuel. Your vehicle may run out of fuel.To start the engine using the remote start feature, do the
following:
1. Aim the remote keyless entry transmitter, equipped
with the remote vehicle start button, at the vehicle.
2. Press and release the transmitter’s lock button, then
immediately press and hold the remote vehicle start
button until the vehicle’s turn signal lamps ash,
or for at least two seconds, if the vehicle’s lights are
not visible. The vehicle’s doors will be locked.
3. When the vehicle’s engine starts, the parking lamps
will turn on and remain on while the engine is
running.
After a remote start, the engine will automatically shut
off after 10 minutes unless a time extension has
been done or the vehicle’s key is inserted into the
ignition switch and turned to RUN.
The maximum number of remote starts or remote start
attempts between ignition cycles with the key is two.
If it is the vehicle’s rst remote start, and the engine is
still running, repeat Steps 1 and 2 for a 10 minute
time extension. Ten minutes will be added to the
remaining minutes of the rst remote start. The
10 minute time extension is considered a second
remote start.
2-8

After two remote starts have been provided, the
vehicle’s ignition switch must be turned to RUN and
then back to LOCK using the key before the remote
start procedure can be used again.
If you enter the vehicle after a remote start, and the
engine is running, insert the key into the ignition switch
and turn it to the RUN position to drive the vehicle.
To manually shut off the engine after a remote start,
do any of the following:
Aim the remote keyless entry transmitter at the
vehicle and press the remote start button until
the parking lamps turn off.
Turn on the hazard warning ashers.
Insert the vehicle’s key into the ignition switch and
turn the switch to RUN and then back to LOCK.The remote vehicle start feature will not operate if:

The vehicle’s hood, liftgate or doors are not closed.
The hazard warning ashers are on.
There is an emission control system malfunction.

{CAUTION:
It can be dangerous to drive with the liftgate
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 liftgate open
or if electrical wiring or other cable
connections must pass through the seal
between the body and the liftgate:
Make sure all other windows are shut.
Turn the fan on your heating or cooling
system to its highest speed and select the
control setting that will force outside air
into your vehicle. SeeDual Climate Control
System on page 3-25.
If you have air outlets on or under the
instrument panel, open them all the way.
SeeEngine Exhaust on page 2-40.To close the liftgate, pull down on the handle, then
rmly shut the liftgate. Do not drive with the liftgate
open, even slightly.
2-23

Disarming with Your Key
Your alarm system will disarm when you use your key
to unlock the driver’s door. The security light will
stop ashing to let you know the system is no longer
armed. If you would like your key not to disarm the alarm
system, seeDIC Vehicle Personalization (Uplevel
Only) on page 3-68.

PASS-Key
®III uses a radio frequency transponder in
the key that matches a decoder in your vehicle.
PASS-Key®III Operation
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 do
not have to do anything
different 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 shuts down the vehicle’s
starter and fuel systems. The starter will not work
and fuel will stop being delivered to the engine.
2-28

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 message
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 undamaged, try another ignition key. At this time,
you may also want to check the instrument panel PASS
KEY fuse. 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 or
a locksmith who can service the PASS-Key
®III to
have a new key made. SeeFuses and Circuit Breakers
on page 5-87.
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.
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 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.To program the new key, do the following:
1. Verify the new key has PK3 stamped on it.
2. Insert the original, already programmed key into the
ignition lock cylinder 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 RUN
within 10 seconds of removing the previous key.
5. The security message will turn off once the key has
been programmed. It may not be apparent that the
security message went on due to how quickly
the key is programmed.
6. Repeat Steps 1 through 4 if additional keys are to
be programmed.
If you are ever driving and the security message
comes on and stays on, you will 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 a PASS-Key
®III key, see your
dealer or a locksmith who can service PASS-Key®III
to have a new key made.
