You can also program the remote vehicle start system
to start up the vehicle’s automatic climate control
system. If this feature is turned on, the system monitors
the outside temperature and turns on the rear window
defogger, front window defogger, and heated or
ventilated seats, if equipped. See “Personal Settings
Menu” underVehicle Personalization on page 2-47.
Laws in some local communities may restrict the use of
remote starters, for example, requiring 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,
each with 10 minutes of engine running. If you press the
remote start button on the keyless access transmitter
again before the rst 10 minutes of engine running time
has expired, 10 minutes is added to the remaining
minutes. For example, if the remote start button
is pressed again after ve minutes of the engine run
time, 10 minutes is added and you now have 15 minutes
with the engine running. Once two remote starts or
20 minutes of the engine running have been provided,
the vehicle must be started using the keyless access
with pushbutton start feature, if the engine needs to be
restarted. SeeStarting the Engine on page 2-24for
more information regarding the keyless ignition.The remote start feature will not operate if any of the
following occur:
The check engine light is displayed.
The valet lockout switch is on.
The keyless access transmitter is in the vehicle.
The vehicle’s hood is open.
The vehicle personalization feature is not enabled.
An unauthorized vehicle entry or a vehicle theft
was attempted.
Your keyless access transmitter, with the remote start
button, provides an increased range of operation.
However, the range may be less while the vehicle is
running. 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, seeKeyless Access
System on page 2-3.

Theft-Deterrent Systems
Vehicle theft is big business, especially in some cities.
Although your vehicle has a number of theft-deterrent
features, we know that nothing we put on it can make it
impossible to steal.
Theft-Deterrent System
Your vehicle has a theft-deterrent alarm system.
The security light
is located on the
instrument panel
cluster.
If the ignition is off and a door is open, the security light
will ash, reminding you to arm the theft-deterrent
system.
To arm the system, do one of the following:
Press the lock button on the keyless access
transmitter. If the door is closed when the lock button
is pressed, the security light will stay illuminated for
30 seconds. After the security light goes off, the
theft-deterrent system is armed. Pressing the lock
button twice will arm the system immediately.If the vehicle is locked using the keyless access
transmitter and the trunk lid, hood or a door is open
or not closed completely, the security light will ash
for 60 seconds and then turn off. At this time, the
theft-deterrent system is armed but the alarm will not
sound if the trunk lid, hood or door that was not
closed completely is tampered with or opened. The
alarm will sound for the trunk lid, hood or a door that
was completely closed at the time the vehicle was
locked using the keyless access transmitter.
Open the door. Lock the door with the power door
lock switch or lock button on the keyless access
transmitter. The security light should ash. Close the
door. The security light will stop ashing and stay on.
After 30 seconds the light should turn off, the
theft-deterrent system is armed.
Passive Arming, if activated through the vehicle
personalization feature, will arm the system
automatically after you close the door and take at
least one keyless access transmitter with you. The
security light will turn on. After 60 seconds the light
should turn off. The theft-deterrent system is armed.
SeeVehicle Personalization on page 2-47.
If a door, hood, or the trunk is opened without the
keyless access transmitter, the horn will sound for
30 seconds and the lamps will ash for two minutes.
The vehicle cannot be started without a keyless access
transmitter.
2-19
The Theft-Deterrent system will not arm if:
The key is used to lock the driver’s door.
The driver’s door is locked using the power door
lock switch after the doors are closed.
If the vehicle is locked using the keyless access
transmitter and the trunk lid, hood or a door is open or
not closed completely, the security light will ash for
60 seconds and then turn off. At this time, the
theft-deterrent system is armed but the alarm will not
sound if the trunk lid, hood or door that was not closed
completely is tampered with or opened. The alarm
will sound for the trunk lid, hood or a door that was
completely closed at the time the vehicle was locked
using the keyless access transmitter.
The vehicle can be programmed to automatically unlock
the doors and disarm the theft-deterrent system when
you approach the vehicle and the keyless access
transmitter is with you. SeeVehicle Personalization
on page 2-47.
Pressing the unlock button on the keyless access
transmitter or using the key to unlock the driver’s door
disarms the theft-deterrent system. Unlocking a door
any other way while the system is armed will activate
the alarm.
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 switch
or the keyless access transmitter and close the
door. Wait approximately 30 seconds until the
security light goes off.
3. Reach in and open the door using the inside door
handle. The horn will sound and the exterior lamps
will ash.
You can turn off the alarm by pressing the unlock
button on the keyless access transmitter or by starting
the car.
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, seeFuses and Circuit Breakers on
page 5-95. 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.

Engine Coolant Heater
Your vehicle may be equipped with an engine coolant
heater.
In very cold weather, 0°F (−18°C) or colder, the engine
coolant heater can help. You will get easier starting
and better fuel economy during engine warm-up.
Usually, the coolant heater should be plugged in a
minimum of four hours prior to starting your vehicle.
At temperatures above 32°F (0°C), use of the coolant
heater is not required.
To Use the Engine Coolant Heater
1. Turn off the engine.
2. Open the hood and unwrap the electrical cord.
The cord is located in the engine compartment
on the driver’s side of the vehicle near the engine
oil dipstick. SeeEngine Compartment Overview
on page 5-12for more information on location.
You must remove the plastic cap to access the plug.
3. Plug it into a normal, grounded 110-volt AC outlet.
{CAUTION:
Plugging the cord into an ungrounded outlet
could cause an electrical shock. Also, the
wrong kind of extension cord could overheat
and cause a re. You could be seriously
injured. Plug the cord into a properly grounded
three-prong 110-volt AC outlet. If the cord will
not reach, use a heavy-duty three-prong
extension cord rated for at least 15 amps.
4. Before starting the engine, be sure to unplug and
store the cord as it was before to keep it away
from moving engine parts. If you do not, it could be
damaged.
How long should you keep the coolant heater plugged
in? The answer depends on the outside temperature, the
kind of oil you have, and some other things. Instead
of trying to list everything here, we ask that you contact
your dealer in the area where you will be parking
your vehicle. The dealer can give you the best advice
for that particular area.

The rear window defogger will turn off about 10 minutes
after the button is pressed, or if the vehicle’s speed
is above 30 mph (48 km/h), the rear defogger will stay
on continuously. If turned on again, the defogger
will only run for about ve minutes before turning off.
The defogger can also be turned off by pressing
the button again or by turning off the engine.
The heated outside rearview mirrors will heat to help
clear fog or frost from the surface of the mirror when
the rear window defogger button is on.
Notice:Using a razor blade or sharp object to
clear the inside rear window may damage the rear
window defogger. Repairs would not be covered
by your warranty. Do not clear the inside of the rear
window with sharp objects.
Outlet Adjustment
Use the lever located in the center of each outlet to
change the direction of the air ow, either side-to-side or
up and down. Use the thumbwheels to open or close
the outlets to adjust the air ow.Turn the thumbwheel to the right to open the outlets
completely and allow the maximum amount of air
to enter your vehicle. Turn the thumbwheel to the left to
close the outlets and minimize the amount of air
entering the vehicle.
Operation Tips
Clear away any ice, snow or leaves from the air
inlets at the base of the windshield that may
block the ow of air into your vehicle.
Use of non-GM approved hood de ectors may
adversely affect the performance of the system.
Keep the path under the front seats clear of objects
to help circulate the air inside of your vehicle more
effectively.
If the air ow seems low when the fan speed is at
the highest setting, the passenger compartment
air lter may need to be replaced. For more
information, seePassenger Compartment Air Filter
on page 3-58.
