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.

Battery Run-Down Protection
Your vehicle has a battery run-down feature designed to
protect the vehicle’s battery.
When any interior lamp (trunk, reading lamps, or dome
lamp) is left on when the ignition is turned off, the
battery run-down protection system automatically shuts
the lamp off after 20 minutes. This prevents draining
of the battery.
To reactivate the interior lamps, do one of the following:
Open any door.
Press any Remote Keyless Entry (RKE) transmitter
button.
Press the power door lock switch.
Press the remote trunk release.
Turn the lamp that was left on to off and then to
on again.
Accessory Power Outlet(s)
Accessory power outlets can be used to connect
auxiliary electrical equipment, such as a cellular
telephone or CB radio.There are two accessory power outlets, located on the
center console below the climate controls. If the vehicle
has a Traction Control System (TCS), one accessory
power outlet is in the center storage console and the
other is on the center console below the climate controls.
To use an outlet, remove the protective cap. When not in
use, always cover the outlet with the protective cap. The
accessory power outlet is operational at all times.
Notice:If electrical devices are left plugged into a
power outlet, the battery may drain causing your
vehicle not to start or damage to the battery.
This would not be covered by the warranty. Always
unplug all electrical devices when turning off
your vehicle.
Certain electrical accessories are not compatible with
the accessory power outlet and could result in blown
vehicle or adapter fuses. If you experience a problem,
see your dealer/retailer for additional information on
the accessory power outlet.
Notice:Adding any electrical equipment to your
vehicle may damage it or keep other components
from working as they should. The repairs would not
be covered by your warranty. Do not use equipment
exceeding maximum amperage rating of 20 amperes.
Check with your dealer/retailer before adding
electrical equipment.

Have you recently changed brands of fuel?
If so, be sure to fuel your vehicle with quality fuel. See
Gasoline Octane on page 5-6. Poor fuel quality causes
the engine not to run as efficiently as designed. You
might notice this as stalling after start-up, stalling when
you put the vehicle into gear, mis ring, hesitation on
acceleration, or stumbling on acceleration — these
conditions might go away once the engine is warmed up.
This will be detected by the system and cause the light to
turn on.
If you experience one or more of these conditions,
change the fuel brand you use. It will require at least
one full tank of the proper fuel to turn the light off.
If none of the above steps have made the light turn off,
your dealer/retailer can check the vehicle. Your
dealer/retailer has the proper test equipment and
diagnostic tools to x any mechanical or electrical
problems that might have developed.Emissions Inspection and Maintenance
Programs
Some state/provincial and local governments have or
might begin programs to inspect the emission control
equipment on your vehicle. Failure to pass this
inspection could prevent you from getting a vehicle
registration.
Here are some things you need to know to help your
vehicle pass an inspection:
Your vehicle will not pass this inspection if the check
engine light is on or not working properly.
Your vehicle will not pass this inspection if the OBD
(on-board diagnostic) system determines that critical
emission control systems have not been completely
diagnosed by the system. The vehicle would be
considered not ready for inspection. This can happen if
you have recently replaced the battery or if the
battery has run down. The diagnostic system is
designed to evaluate critical emission control systems
during normal driving. This can take several days
of routine driving. If you have done this and your vehicle
still does not pass the inspection for lack of OBD
system readiness, your dealer/retailer can prepare the
vehicle for inspection.

the system is reset after an oil change. It alerts you to
change the oil on a schedule consistent with your driving
conditions.
In addition to the engine oil life system monitoring the
oil life, additional maintenance is recommended in
the Maintenance Schedule in this manual. See
Scheduled Maintenance on page 6-4andEngine Oil on
page 5-21.
Always reset the engine oil life system after an oil
change. See “How to Reset the Engine Oil Life System”
underEngine Oil Life System on page 5-24.
Tire Pressure:The pressure for each tire can be
viewed in the DIC. The tire pressure is shown in either
pounds per square inch (psi) or kilopascals (kPa).

displays for the front tires. Press the information
button again until LR ## PSI (kPa) ## RR displays for
the rear tires.
If a low tire pressure condition is detected by the system
while driving, a message advising you to check the tire
pressure appears in the display. SeeInflation - Tire
Pressure on page 5-68andDIC Warnings and Messages
on page 3-46for more information.Personalization
MENU:Press this button while the ignition is on to
scroll through each of the personalization options in the
