Vehicle Damage Warnings
Also, in this manual you will nd these notices:
Notice:These mean there is something that could
damage your vehicle.
A notice tells about something that can damage the
vehicle. Many times, this damage would not be covered
by your vehicle’s warranty, and it could be costly. But
the notice will tell what to do to help avoid the damage.
When you read other manuals, you might see
CAUTION and NOTICE warnings in different colors
or in different words.
There are also warning labels on the vehicle. They use
the same words, CAUTION or NOTICE.
Vehicle Symbols

Section 2 Features and Controls
2-1

Changes or modications to this system by other than
an authorized service facility could void authorization to
use this equipment.
At times you may notice a decrease in operating range.
This is normal for any remote keyless entry system. If the
transmitter does not work or if you have to stand closer to
your vehicle for the transmitter to work, try this:
Check the distance. You may be too far from your
vehicle. You may need to stand closer during rainy
or snowy weather.
Check the location. Other vehicles or objects may
be blocking the signal. Take a few steps to the left
or right, hold the transmitter higher, and try again.
Check to determine if battery replacement is
necessary. See “Battery Replacement” under
Remote Keyless Entry System Operation on
page 2-4.
If you are still having trouble, see your dealer or a
qualied technician for service.
Remote Keyless Entry System
Operation
The vehicle’s doors can be locked and unlocked, and the
trunk can be opened from approximately 3 feet (1 m) up
to 60 feet (18 m) away with the remote keyless entry
transmitter. If your vehicle has the remote start feature,
you can also start the vehicle’s engine with the remote
keyless entry transmitter.

The following functions may be available with your
vehicle’s remote keyless entry system:
/(Remote Vehicle Start):If your vehicle has this
feature, the engine may be started from outside the
vehicle using the remote keyless entry transmitter.
See “Remote Vehicle Start” at the end of this section
for more detailed information.
Q(Lock):Press the lock button to lock all the doors.
If enabled through the Driver Information Center (DIC),
the parking lamps may ash once to indicate locking has
occurred, or the horn may chirp when the lock button is
pressed again within ve seconds from the previous
press of the lock button. See “FOB LOCK FEEDBACK”
underDIC Vehicle Personalization on page 3-75for
additional information. If the vehicle has the content
theft-deterrent system, pressing the lock button may also
arm it. SeeContent Theft-Deterrent on page 2-18.
"(Unlock):Press the unlock button to unlock the
driver’s door. If the button is pressed again within
ve seconds, all remaining doors will unlock. The interior
lamps will come on and stay on for 20 seconds or until
the ignition is turned on. If enabled through the DIC, the
parking lamps can be programmed to come on for a set
amount of time when the vehicle is unlocked using the
remote keyless entry transmitter.See “EXT (Exterior) LIGHT DELAY” underDIC Vehicle
Personalization on page 3-75. If the vehicle has the
content theft-deterrent system, pressing the unlock
button on the remote keyless entry transmitter may
disarm it. SeeContent Theft-Deterrent on page 2-18.
V(Remote Trunk Release):Press and hold this
button for approximately one second to release the trunk
lid. The transaxle must be in PARK (P) for this feature to
operate.
L(Panic Alarm):Press this button to activate the
alarm. The ignition must be in OFF or ACCESSORY for
the alarm to work. When the alarm button is pressed, the
headlamps will ash and the horn will sound repeatedly
for two minutes. The alarm will turn off when the ignition is
moved to RUN or the alarm button is pressed again.
Matching Transmitter(s) to Your Vehicle
Each remote keyless entry transmitter is coded to
prevent another transmitter from unlocking your vehicle.
If a transmitter is lost or stolen, a replacement can be
purchased through your GM dealer. Remember to bring
any additional transmitters so they can also be re-coded
to match the new transmitter. Once your dealer has
coded the new transmitter, the lost transmitter will not
unlock your vehicle. The vehicle can have a maximum of
four transmitters matched to it.
2-5

Remote Vehicle Start
Your vehicle may have a remote starting feature. This
feature allows you to start the engine from outside of the
vehicle. It may also start up the vehicle’s heating or air
conditioning systems and rear window defogger. When
the remote start system is active, the climate control
system will heat and cool the inside of the vehicle based
on the outside temperature. The rear window defogger
will be turned on by the climate control system when it is
heating the inside of the vehicle. Normal operation of the
system will return after the key is turned to the RUN
position.
Laws in some 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.
Do not use the remote start feature if your vehicle
is low on fuel. Your vehicle may run out of fuel.The remote start feature provides two separate starts
per ignition cycle, each with 10 minutes of engine
running time.
The remote vehicle start feature needs to be reset
after your vehicle’s engine is started two times using
the transmitter’s remote start button. The remote start
system is reset by inserting the vehicle’s key into the
ignition switch and turning it to RUN. SeeIgnition
Positions on page 2-23for information regarding the
ignition positions on your vehicle.
Your remote keyless entry transmitter with the remote
start button provides an increased range of operation.
You can start your vehicle from an average range of
approximately 492 feet (150 m) away. However the
range may be less while the vehicle is running, and as
a result, you may need to be closer to your vehicle to
turn it off than you were to turn it on.
There are other conditions which can affect the
performance of the transmitter, seeRemote Keyless
Entry System on page 2-3for additional information.
2-7

/(Remote Start):If your vehicle has the remote start
feature, the keyless entry transmitter will have a button
with this symbol on it.
To start the vehicle using the remote start feature, do
the following:
1. Aim the transmitter at the vehicle.
2. Press and release the transmitter’s lock button,
then immediately press and hold the transmitter’s
remote start button for 4 seconds or until the
turn signal lamps ash. The vehicle’s doors
will lock.
3. When the vehicle’s engine starts, the parking lamps
will turn on and remain on while the engine is
running.
The engine will shut off automatically 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.
If you enter the vehicle after a remote start, and
the engine is still running, insert the key into
the ignition switch and turn it to RUN to drive
the vehicle.4. To manually shut off a remote start, do any of the
following. The parking lamps will turn off:
Aim the remote keyless entry transmitter at the
vehicle and press the remote start button.
Turn on the hazard warning ashers.
Turn the ignition switch to RUN and then to OFF.
Your vehicle’s engine may be started two times using the
transmitter’s remote start feature. If only one remote start
procedure has been done, since last driving the vehicle,
or resetting the remote start system, the engine may be
started again remotely following the remote start
procedure a second time
If the remote start procedure is used again before
the rst 10 minute time frame has ended, the
rst 10 minutes will immediately expire and the
second 10 minute time frame will start.
2-8

The remote vehicle start feature will not operate if any
of the follow occur:
The remote start system is disabled through
the DIC.
The vehicle’s key is in the ignition.
A door on the vehicle is open.
The vehicle’s hood is open.
The hazard warning ashers are on.
The check engine light is on. SeeMalfunction
Indicator Lamp on page 3-41.
The engine coolant temperature is too high.
The oil pressure is low.
Two remote vehicle starts have already been
provided for that ignition cycle.
If a remote start is attempted and is unsuccessful, the
Driver Information Center (DIC) will display REMOTE
START DISABLED.Vehicles that have the remote vehicle start feature are
shipped from the factory with the remote vehicle start
system enabled. The system may be enabled or disabled
through the DIC. See “REMOTE START” underDIC
Vehicle Personalization on page 3-75for additional
information. If your vehicle does not have the DIC feature,
and remote vehicle start was installed at the dealership,
you will need to have the dealership enable or disable
the system.
Remote Start Ready
If your vehicle does not have the remote vehicle start
feature, it may have the remote start ready feature. This
feature allows your dealer to add the manufacturer’s
remote vehicle start feature.
If the keyless entry transmitter has a plus (+) symbol
on the back cover, your vehicle has the remote
start ready feature. You can lock or unlock your
vehicle from approximately 492 feet (150 m) away.
See your dealer if you would like to add the
manufacturer’s remote vehicle start feature to
your vehicle.
2-9

When you want to open a rear door when the security
lock is on, do the following:
1. Unlock the door using the remote keyless entry
transmitter, if equipped, the power door lock
switch, or by lifting the rear door manual lock.
2. Open the door from the outside.
To cancel the rear door security lock, do the following:
1. Unlock the door and open it from the outside.
2. Insert the key into the security lock slot and turn
it so the slot is in the vertical position.
Lockout Protection
The lockout protection feature makes it more difficult
to lock the key in the vehicle. If the driver’s door is open
while the key is in the ignition, the door cannot be locked
with the power door lock switch.
This feature cannot guarantee that you will never be
locked out of the vehicle. If the key is not left in the
ignition, or, if the manual door lock is used, the key
could still be locked inside the vehicle. Always
remember to take the key with you.
Trunk
{CAUTION:
It can be dangerous to drive with the trunk lid
open because carbon monoxide (CO) gas can
come into your vehicle. You cannot 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 and select the
control setting that will force outside air
into your vehicle. See Climate Control
System.
If you have air outlets on or under the
instrument panel, open them all the way.
SeeEngine Exhaust on page 2-34.
2-13

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 nothing special
needs to be done to arm
or disarm the system.
It works when the key is
inserted or removed
from the ignition.
PASS-Key
®III uses a transponder in the ignition key
that matches a decoder in the vehicle.
When the PASS-Key
®III system senses that the wrong
key has been inserted into the ignition, it shuts down the
vehicle’s starter and fuel systems. The starter will not
work and fuel will stop owing to the engine. If someone
tries to start the vehicle again with the wrong key, the
vehicle will not start. Anyone using a trial-and-error
method to start the vehicle will be discouraged to do so
because of the high number of electrical key codes.When trying to start the vehicle, if the engine does not
start and the STARTING DISABLED warning message
on the Driver Information Center (DIC) 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 fuse. SeeFuses and Circuit
Breakers on page 5-93. If the engine still does not start
with the other key, the vehicle needs service. If the
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 7-6for more information.
It is possible for the PASS-Key
®III decoder to accept
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 programmed keys are lost or do
not operate, see your dealer or a locksmith who
can service PASS-Key
®III to have keys made and
programmed to the system.
2-21

To program the new key do the following:
1. Verify that the new key has PK3 stamped on it.
2. Insert the master 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 RUN
within ve seconds of removing the original key.
5. The SERVICE THEFT SYSTEM warning message
on the DIC will turn off, once the key has been
programmed. It may not be apparent that the
SERVICE THEFT SYSTEM warning message went
on due to how quickly the key is programmed.
6. Repeat Steps 1 through 5 if additional keys are to
be programmed.
If the SERVICE THEFT SYSTEM warning message
appears and stays on the DIC while the vehicle is being
driven, the engine will be able to be restarted if it is turned
off. Your PASS-Key
®III system, however, is not working
properly and must be serviced by your dealer. The
vehicle is not protected by the PASS-Key
®III system at
this time.
If the PASS-Key
®III key is lost or stolen, 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. SeeTowing
a Trailer on page 4-38for the trailer towing
capabilities of your vehicle and more
information.
Following break-in, engine speed and load can be
gradually increased.
