After the engine has been started two times, or one
time with a time extension, the vehicle’s ignition must be
turned to ON/RUN using the key before the remote start
procedure can be used again. SeeIgnition Positions on
page 2-22for information regarding the ignition positions
on your vehicle.
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 ashers are on.
The check engine light is on. SeeMalfunction
Indicator Lamp on page 3-38.
The engine coolant temperature is too high.
The oil pressure is low.
Two remote vehicle starts, or one start with a time
extension, 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” underDIC
Vehicle Personalization on page 3-50for additional
information.
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/retailer to add the
manufacturer’s remote vehicle start feature.
See your dealer/retailer if you would like to add the
manufacturer’s remote vehicle start feature to your
vehicle.

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 three chirps are heard when the unlock or lock button
is pressed on the RKE transmitter, it means that the
content theft security system alarm was previously
triggered.

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). Vehicles
with an engine coolant heater should be plugged in at
least four hours before starting the vehicle. 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 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 and
3.6L V6 engines, the engine coolant heater cord is
located on the driver side around the battery box.
SeeEngine Compartment Overview on page 5-16
for more information on location.
{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.
3. Plug the cord into a normal, grounded 110-volt AC
outlet.
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 the vehicle for the best
advice on this.

Gasoline Octane
If the vehicle has the 2.4L L4 engine (VIN Code B),
the 3.5L V6 engine (VIN Code K), or the 3.5L V6 engine
(VIN Code N), use regular unleaded gasoline with a
posted octane rating of 87 or higher. 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 the 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.
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. SeeAdditives on page 5-7
for additional information.
California Fuel
If the 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, the 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 the
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 the vehicle 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 hood release
handle with this symbol
on it. It is located
inside the vehicle to
the left of the steering
column.

Page 273 of 420
2. Then go to the front of the vehicle and push the
secondary hood release handle toward the driver
side of the vehicle.3. Lift the hood.
4. After the hood is slightly lifted, it will continue to
open to the full position. Before closing the hood,
be sure all the ller 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.
