You can start your vehicle’s engine from approximately
197 feet (60 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 (RKE) System on page 2-4for additional
information.
/(Remote Start):This button will be on the RKE
transmitter if you have remote start.
To start the vehicle using the remote start feature:
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 until the vehicle’s turn signal
lamps ash.
When the vehicle starts, the parking lamps will turn
on and remain on while the engine is running.
3. If it is the rst remote start since the vehicle has
been driven, repeat these steps, while the engine
is still running, to extend the engine running time
by 10 minutes. Remote start can be extended
one time.
After entering the vehicle during a remote start, insert
and turn the key to ON/RUN to drive the vehicle.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:
Aim the RKE transmitter at the vehicle and press
and release the remote start button.
Turn on the hazard warning ashers.
Turn the ignition switch ON/RUN and then
LOCK/OFF.
The parking lamps will turn off to indicate the
engine is 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 rst 10 minute time frame has ended, the rst
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.

Disarming the System
To disarm the system, do one of the following:
Press the RKE transmitter unlock button.
Turn the ignition to ON/RUN.
If you want to lock the vehicle without arming the
content theft system, lock the vehicle with the manual
lock knob on the doors or with the inside power
door lock switches.
Once the system is disarmed, the security light will stop
ashing.
How the System Alarm is Activated
To activate the system if it is armed:
Open the driver’s door or trunk. A ten second
pre-alarm chirp will sound followed by a
thirty second full alarm of horn and lights.
Open any other door. A full alarm of horn and lights
will immediately sound for thirty seconds.
Open the hood. If the vehicle has the remote start
feature, it will activate the full alarm.
When an alarm event has nished, the system will
re-arm itself automatically.
How to Turn Off the System Alarm
To turn off the system alarm:
Press the lock button on the RKE transmitter.
The system will then re-arm itself.
Press the unlock button on the RKE transmitter.
This will also disarm the system.
Insert the key in the ignition and turn it on. This will
also disarm the system.
How to Detect a Tamper Condition
If you hear three chirps when the unlock or lock button
is pressed on the RKE transmitter, it means that the
content theft security system alarm was previously
triggered.

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’s 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’s
side around the battery box. SeeEngine
Compartment Overview on page 5-14for more
information on location.
3. Plug the cord 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/retailer in the area where you will be
parking your vehicle. The dealer/retailer can give you
the best advice for that particular area.

If your vehicle has the 3.6L V6 engine (VIN Code 7),
use regular unleaded gasoline with a posted octane
rating of 87 or higher. For best performance or trailer
towing, you could choose to use middle grade 89 octane
unleaded gasoline. If the octane rating is less than
87, you might notice an audible knocking noise when
you drive, commonly referred to as spark knock. If
this occurs, use a gasoline rated at 87 octane or higher
as soon as possible. If you are using gasoline rated
at 87 octane or higher and you hear heavy knocking, the
engine needs service.
If your vehicle has the 2.4L L4 engine (VIN Code B),
use premium unleaded gasoline with a posted octane
rating of 91 or higher. You can also use regular
unleaded gasoline rated at 87 octane or higher, but
your vehicle’s acceleration could be slightly reduced,
and you might notice a slight audible knocking
noise, commonly referred to as spark knock. If the
octane is less than 87, you might notice a heavy
knocking noise when you drive. If this occurs, use a
gasoline rated at 87 octane or higher as soon as
possible. Otherwise, you could damage the engine. If
you are using gasoline rated at 87 octane or higher and
you hear heavy knocking, the engine needs service.Gasoline Speci cations
At a minimum, gasoline should meet ASTM speci cation
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. See
Additives on page 5-8for additional information.
California Fuel
If your vehicle is certi ed to meet California Emissions
Standards, it is designed to operate on fuels that
meet California speci cations. See the underhood
emission control label. If this fuel is not available
in states adopting California emissions standards, your
vehicle will operate satisfactorily on fuels meeting
federal speci cations, but emission control system
performance might be affected. The malfunction
indicator lamp could turn on and your vehicle might fail
a smog-check test. SeeMalfunction Indicator Lamp
on page 3-38. 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 your warranty.

Checking Things Under
the Hood
{CAUTION:
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.
{CAUTION:
Things that burn can get on hot engine parts
and start a re. These include liquids like fuel,
oil, coolant, brake uid, windshield washer and
other uids, 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 handle with
this symbol on it. It is
located under the
instrument panel on
the driver’s side of the
vehicle.
