For a full description of OnStar services and system
limitations, see the OnStar Owner’s Guide in the
glove box.
OnStar service is subject to the OnStar terms and
conditions included in the OnStar Subscriber
Information.
OnStar service cannot work unless the vehicle is in a
place where OnStar has an agreement with a wireless
service provider for service in that area. OnStar service
also cannot work unless the vehicle is in a place where
the wireless service provider OnStar has hired for that
area has coverage, network capacity and reception when
the service is needed, and technology that is compatible
with the OnStar service. Not all services are available
everywhere, particularly in remote or enclosed areas, or
at all times.The OnStar system can record and transmit vehicle
information. This information is automatically sent to an
OnStar call center when
Qis pressed,]is pressed,
or if the airbags or ACR system deploy. This information
usually includes the vehicle’s GPS location and, in
the event of a crash, additional information regarding
the crash that the vehicle was involved in (e.g. the
direction from which the vehicle was hit). When
the virtual advisor feature of OnStar hands-free calling
is used, the vehicle also sends OnStar the vehicle’s
GPS location so they can provide services where it is
located.
Location information about the vehicle is only available
if the GPS satellite signals are unobstructed and
available.
The vehicle must have a working electrical system,
including adequate battery power, for the OnStar
equipment to operate. There are other problems OnStar
cannot control that may prevent OnStar from providing
OnStar service at any particular time or place. Some
examples are damage to important parts of the vehicle
in a crash, hills, tall buildings, tunnels, weather or
wireless phone network congestion.

Servicing Your Airbag-Equipped
Vehicle
Airbags affect how the vehicle should be serviced.
There are parts of the airbag system in several places
around the vehicle. Your dealer/retailer and the
service manual have information about servicing the
vehicle and the airbag system. To purchase a service
manual, seeService Publications Ordering Information
on page 8-15.
{WARNING:
For up to 10 seconds after the ignition is turned off
and the battery is disconnected, an airbag can still
inflate during improper service. You can be injured
if you are close to an airbag when it inflates. Avoid
yellow connectors. They are probably part of the
airbag system. Be sure to follow proper service
procedures, and make sure the person performing
work for you is qualified to do so.
Adding Equipment to Your
Airbag-Equipped Vehicle
Q:Is there anything I might add to or change
about the vehicle that could keep the airbags
from working properly?
A:Yes. If you add things that change the vehicle’s
frame, bumper system, height, front end or side
sheet metal, they may keep the airbag system from
working properly. Changing or moving any parts
of the front seats, safety belts, the airbag sensing
and diagnostic module, steering wheel, instrument
panel, roof-rail airbag modules, ceiling headliner
or pillar garnish trim, front sensors, or airbag wiring
can affect the operation of the airbag system.
In addition, the vehicle has a passenger sensing
system for the right front passenger position, which
includes sensors that are part of the passenger’s
seat. The passenger sensing system may not
operate properly if the original seat trim is replaced
with non-GM covers, upholstery or trim, or with
GM covers, upholstery or trim designed for a
different vehicle.

Remote Keyless Entry (RKE)
System
SeeRadio Frequency Statement on page 8-18for
information regarding Part 15 of the Federal
Communications Commission (FCC) Rules and
RSS-210/211 of Industry and Science Canada.
Changes or modifications to this system by other than
an authorized service facility could void authorization to
use this equipment.
If there is a decrease in the RKE operating range, try this:
•Check the distance. The transmitter may be too far
from the vehicle. 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 the transmitter’s battery. See “Battery
Replacement” later in this section.
•If the transmitter is still not working correctly, see
your dealer/retailer or a qualified technician for
service.
Remote Keyless Entry (RKE)
System Operation
The Remote Keyless Entry (RKE) transmitter functions
work up to 60 m (195 feet) away from the vehicle.

Battery Replacement
Replace the battery if the KEY FOB BATT LOW
message displays in the DIC. See “KEY FOB BATT
LOW” underDIC Warnings and Messages on page 4-42.
Notice:When replacing the battery, do not touch
any of the circuitry on the transmitter. Static
from your body could damage the transmitter.
To replace the battery:
1. Separate the transmitter with a flat, thin object
inserted into the notch on the side.
2. Remove the old battery. Do not use a metal object.3. Insert the new battery, positive side facing up.
Replace with a CR2032 or equivalent battery.
4. Snap the transmitter back together.
Remote Vehicle Start
Your vehicle may have a remote starting feature.
This feature allows you to start the engine from outside
the vehicle. It may also start the vehicle’s heating or
air conditioning systems and rear window defogger.
When the remote start system is active and the vehicle
has an automatic climate control system, it will
automatically regulate the inside temperature. Normal
operation of the system will return after the ignition
key is turned to ON/RUN.
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.

Window Indexing (Coupe and
Retractable Hardtop)
This feature automatically lowers the window a small
amount when the door is opened. Then, when the door
is closed, the window will automatically raise fully.
If the vehicle loses power or the window freezes, this
feature may not work. From outside the vehicle,
close the door and push the window inward so that the
glass goes under the molding.
Power Window Initialize (Coupe and
Retractable Hardtop)
After a power reconnect, such as battery replacement,
the indexing feature will not function until the system
is initialized. This procedure needs to be done for each
individual window. Once power is restored:
1. Close the door.
2. Raise the window by pulling the power window
switch up.
3. Hold the window switch up for two seconds after
the window is closed. Release the switch. Then
hold the switch up again for two seconds.4. Lower the window all the way down. Hold the
switch down for two seconds.
5. Repeat the procedure for each window, including
the rear quarter windows on retractable hardtop
models, until all windows are initialized.
Express-Down Window
The express-down feature lowers the window all the
way without continuously pressing the AUTO switch.
On sedan and retractable hardtop models, the driver’s
window has the express-down feature. On coupe
models, both the driver’s and front passenger window
have the express-down feature. The front passenger
express-down is activated by the driver’s side switch
only. Press the front of the switch all the way down and
release it to express open the window.
To stop the window while it is lowering, pull the front of
the switch up briefly.

ACC (ACC/ACCESSORY):This position unlocks the
transmission. It also lets you use things like the
radio and windshield wipers while the engine is not
running. To use ACC/ACCESSORY, turn the key
clockwise to the first position. Use this position if your
vehicle must be pushed or towed. SeeRecreational
Vehicle Towing on page 5-23.
R(ON/RUN):This position can be used to operate the
electrical accessories and to display some instrument
panel warning lights. The ignition switch will stay in this
position while the engine is running.
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 the vehicle
if the battery is allowed to drain for an extended
period of time.
/(START):This position starts the engine. When the
engine starts, release the key. The ignition switch will
return to the ON/RUN position for normal driving.
A warning tone will sound when the driver door is
opened, the ignition is in ACC/ACCESSORY or
LOCK/OFF and the key is in the ignition.
Retained Accessory Power (RAP)
These vehicle accessories can be used for up to
10 minutes after the engine is turned off:
•Audio System
•Power Windows
•Heated Seats (if equipped)
•Sunroof (if equipped)
These features continue to work up to 10 minutes after
the ignition is turned to LOCK/OFF.
The power windows, heated seats, and sunroof will
work until any door is opened.
The radio continues to work until the driver door is
opened.
All these features operate when the key is in the
ON/RUN or ACC/ACCESSORY.
Starting the Engine
Move the shift lever to P (Park) or N (Neutral). The
engine will not start in any other position. To restart the
engine when the vehicle is already moving, use
N (Neutral) only.
Notice:Do not try to shift to P (Park) if the vehicle
is moving. If you do, you could damage the
transmission. Shift to P (Park) only when the
vehicle is stopped.
3-21

Starting Procedure
1. With your foot off the accelerator pedal, turn the
ignition to START. When the engine starts, let go
of the key. The idle speed will slow down as
the engine warms. Do not race the engine
immediately after starting it. Operate the engine
and transmission gently to allow the oil to warm
up and lubricate all moving parts.
The vehicle has a Computer-Controlled Cranking
System. This feature assists in starting the engine
and protects components. If the ignition key is turned
to the START position, and then released when the
engine begins cranking, the engine will continue
cranking for a few seconds or until the vehicle starts.
If the engine does not start and the key is held in
START, cranking will be stopped after 15 seconds to
prevent cranking motor damage. To prevent gear
damage, this system also prevents cranking if the
engine is already running. Engine cranking can be
stopped by turning the ignition switch to the ACC/
ACCESSORY or LOCK/OFF position.
Notice:Cranking the engine for long periods of
time, by returning the key to the START position
immediately after cranking has ended, can overheat
and damage the cranking motor, and drain the
battery. Wait at least 15 seconds between each try,
to let the cranking motor cool down.2. If the engine does not start after 5-10 seconds,
especially in very cold weather (below 0°F or−18°C),
it could be flooded with too much gasoline. Try
pushing the accelerator pedal all the way to the floor
and holding it there as you hold the key in START for
up to a maximum of 15 seconds. Wait at least
15 seconds between each try, to allow the cranking
motor to cool down. When the engine starts, let go of
the key and accelerator. If the vehicle starts briefly
but then stops again, repeat these steps. This clears
the extra gasoline from the engine. Do not race the
engine immediately after starting it. Operate the
engine and transmission gently until the oil warms up
and lubricates all moving parts.
Notice:The engine is designed to work with the
electronics in the vehicle. If you add electrical parts
or accessories, you could change the way the
engine operates. Before adding electrical equipment,
check with your dealer/retailer. If you do not, the
engine might not perform properly. Any resulting
damage would not be covered by the vehicle
warranty.

Engine Coolant Heater
The engine coolant heater can provide easier starting
and better fuel economy during engine warm-up in cold
weather conditions at or below 0°F (−18°C). Vehicle
with an engine coolant heater should be plugged in at
least four hours before starting. An internal thermostat in
the plug-end of the cord may exist which will prevent
engine coolant heater operation at temperatures above
0°F (−18°C).
To Use the Engine Coolant Heater
1. Turn off the engine.
2. Open the hood and unwrap the electrical cord. On
the 2.4L L4 ECOTEC
®engine, the engine coolant
heater cord is located near the air cleaner box
on the passenger’ side of the engine compartment.
On the 3.5L, 3.6L and 3.9L V6 engines, the
engine coolant heater cord is located on the driver
side around the battery box. SeeEngine
Compartment Overview on page 6-16for more
information on location.3. Plug the cord into a normal, grounded 110-volt
AC outlet.
{WARNING:
Plugging the cord into an ungrounded outlet could
cause an electrical shock. Also, the wrong kind of
extension cord could overheat and cause a fire.
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 and prevent damage.
The length of time the heater should remain plugged in
depends on several factors. Ask a dealer/retailer in
the area where you will be parking your vehicle for the
best advice in this.
