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 ON/RUN.
To manually shut off a remote start, do any of the
following. The parking lamps will turn off to indicate the
engine is off.
•Aim the RKE transmitter at the vehicle and press
and release the remote start button.
•Turn on the hazard warning flashers.
•Turn the ignition switch to ON/RUN and then
LOCK/OFF.
Your vehicle’s engine can be started two times, per
ignition cycle, using the transmitter’s remote start
feature.
If the remote start procedure is used again before the
first 10 minute time frame has ended, the first
10 minutes will immediately expire and the second
10 minute time frame will start. 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.
•The vehicle’s hood is open.
•The hazard warning flashers are on.
•The check engine light is on. See
Malfunction
Indicator Lamp on page 4-30 .
•The engine coolant temperature is too high.
•The oil pressure is low.
•Two remote vehicle starts have already been
provided for that ignition cycle.
Vehicles that have the remote vehicle start feature are
shipped from the factory with the remote start system
enabled. The system may be enabled or disabled
through the DIC. See “REMOTE START” under DIC
Vehicle Personalization on page 4-43 for additional
information.

To Use the Engine Coolant Heater
1. Turn off the engine.
2. Open the hood and unwrap the electrical cord. Theelectrical cord is located on the passenger side of
the vehicle between the strut and the air
cleaner/filter.
3. Plug it 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 damaged. 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 the vehicle for the
best advice on this.
Automatic Transmission Operation
If the vehicle has an automatic transmission, the
shift lever is located on the console between the seats.
There are several different
positions for the automatic
transmission.
P (Park): This position locks the front wheels. It is the
best position to use when starting the engine because
the vehicle cannot move easily.

Rear Window Defogger
The rear window defogger uses a warming grid to
remove fog from the rear window.
The rear window defogger only works when the ignition
is in ON/RUN.
<(Rear):Press to turn the rear window defogger on or
off. Be sure to clear as much snow from the rear window
as possible. An indicator light comes on to show that the
rear window defogger is on.
The rear window defogger turns off about 15 minutes
after the button is pressed. If turned on again, the
defogger only runs for about seven minutes before
turning off. If the vehicle is moving faster than 50 mph
(80 kph), the rear defogger will stay on. The defogger
can also be turned off by turning off the engine.
Notice: Do not use anything sharp on the inside
of the rear window. If you do, you could cut or
damage the warming grid, and the repairs would
not be covered by the vehicle warranty. Do not
attach a temporary vehicle license, tape, a decal
or anything similar to the defogger grid.
Outlet Adjustment
Use the thumbwheels located next to and below the air
outlets to change the direction of the airflow and to
open and close the outlets.
Operation Tips
•
Clear away any ice, snow or leaves from the air
inlets at the base of the windshield that may
block the flow of air into the vehicle.
•Use of non-GM approved hood deflectors 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 the vehicle more
effectively.

Gasoline Octane
Use regular unleaded gasoline with a posted octane
rating of 87 or higher. If the octane rating is less than 87,
an audible knocking noise, commonly referred to as spark
knock, might be heard when driving. If this occurs, use a
gasoline rated at 87 octane or higher as soon as possible.
If heavy knocking is heard when using gasoline rated at
87 octane or higher, the engine needs service.
Gasoline Speci cations
At a minimum, gasoline should meet ASTM specification
D 4814 in the United States or CAN/CGSB-3.5 or 3.511 in
Canada. Some gasolines contain an octane-enhancing
additive called methylcyclopentadienyl manganese
tricarbonyl (MMT). We recommend against the use of
gasolines containing MMT. SeeAdditives on page 6-6for
additional information.
California Fuel
If the vehicle is certified to meet California Emissions
Standards, it is designed to operate on fuels that meet
California specifications. See the underhood emission
control label. If this fuel is not available in states adopting
California emissions standards, the vehicle will operate
satisfactorily on fuels meeting federal specifications, but
emission control system performance might be affected.
The malfunction indicator lamp could turn on and the
vehicle might fail a smog-check test. See Malfunction
Indicator Lamp on page 4-30 . If this occurs, return to your
authorized dealer/retailer for diagnosis. If it is determined
that the condition is caused by the type of fuel used,
repairs might not be covered by the vehicle warranty.
Additives
To provide cleaner air, all gasolines in the United States
are now required to contain additives that help prevent
engine and fuel system deposits from forming, allowing
the emission control system to work properly. In most
cases, nothing should have to be added to the fuel.

Filling a Portable Fuel Container
{WARNING:
Never fill a portable fuel container while it is in the
vehicle. Static electricity discharge from the
container can ignite the fuel vapor. You can be
badly burned and the vehicle damaged if this
occurs. To help avoid injury to you and others:
•Dispense fuel only into approved containers.
•Do not fill a container while it is inside a
vehicle, in a vehicle’s trunk, pickup bed, or on
any surface other than the ground.
•Bring the fill nozzle in contact with the inside
of the fill opening before operating the nozzle.
Contact should be maintained until the filling
is complete.
•Do not smoke while pumping fuel.
•Do not use a cellular phone while
pumping fuel.
Checking Things Under
the Hood
{WARNING:
An electric fan under the hood can start up and
injure you even when the engine is not running.
Keep hands, clothing, and tools away from any
underhood electric fan.
{WARNING:
Things that burn can get on hot engine parts and
start a fire. These include liquids like fuel, oil,
coolant, brake fluid, windshield washer and other
fluids, and plastic or rubber. You or others could
be burned. Be careful not to drop or spill things
that will burn onto a hot engine.

Hood Release
To open the hood, do the following.1. Pull the interior hoodrelease lever with this
symbol on it. It is
located under the
instrument panel on
the driver’s side of the
vehicle.
2. Then go to the front of the vehicle and push thesecondary hood release lever to the left. It is
located under the front center of the hood toward
the driver’s side of the vehicle.
3. After you have partially lifted the hood, a gas strut will automatically take over to lift and hold the hood
in the fully open position.
Before closing the hood, be sure all the filler caps
are on properly. Lower the hood until the lifting force
of the strut is reduced, then release the hood to
latch fully. Check to make sure the hood is closed
and repeat the process if necessary.

Page 291 of 422

{WARNING:
You can be burned if you spill coolant on hot
engine parts. Coolant contains ethylene glycol,
and it will burn if the engine parts are hot enough.
Do not spill coolant on a hot engine.
When replacing the pressure cap, make sure it is
hand-tight and fully seated.
Engine Overheating
You will find an engine coolant temperature warning
light on your vehicle’s instrument panel. See Engine
Coolant Temperature Warning Light on page 4-29 for
more information.
If Steam Is Coming From Your Engine
{WARNING:
Steam from an overheated engine can burn you
badly, even if you just open the hood. Stay away
from the engine if you see or hear steam coming
from it. Just turn it off and get everyone away from
the vehicle until it cools down. Wait until there is no
sign of steam or coolant before you open the hood.
If you keep driving when your engine is overheated,
the liquids in it can catch fire. You or others could
be badly burned. Stop your engine if it overheats,
and get out of the vehicle until the engine is cool.
Notice: If the engine catches re because of being
driven with no coolant, your vehicle can be badly
damaged. The costly repairs would not be covered
by the vehicle warranty.
