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.

9(Fan Control):Turn the knob clockwise or
counterclockwise to increase or decrease the fan speed.
The fan must be on to run the air conditioning
compressor.
Temperature Control:Turn the knob clockwise or
counterclockwise to increase or decrease the
temperature inside the vehicle.
When it is cold outside−18°C (0°F) or lower, use the
engine coolant heater, if the vehicle has one, to quickly
provide warmer air. An engine coolant heater warms
coolant that the engine uses to warm the inside of the
vehicle. For more information, seeEngine Coolant
Heater on page 3-23.
Air Delivery Mode Control:Turn the knob clockwise
or counterclockwise to change the air delivery settings.
Select from the following modes:
H(Vent):Air is directed to the instrument panel
outlets.
)(Bi-Level):Air is divided between the air to the
instrument panel and floor outlets. Some air may
be directed toward the side windows.
6(Floor):Air is directed to the floor outlets with
some air directed to the side window outlets and
windshield.
-(Defog):This mode clears the windows of fog or
moisture. Air is directed to the windshield and floor
outlets, with some air directed to the side windows.
When this mode is selected, the system automatically
turns off recirculation and tuns the air conditioning
compressor unless the outside temperature is at
or below freezing. The air conditioning compressor
operates although the indicator light is not on. The air
conditioning indicator light turns off when defog is
selected. If the air conditioning button is pressed while
in defog mode, the indicator light turns on. If the
button is pressed again, the light turns off. The
recirculation mode cannot be selected while in the defog
mode. Do not drive the vehicle until all the windows
are clear.
1(Defrost):This mode clears the windshield of fog
or frost more quickly. Air is directed to the windshield,
with some air directed to the floor vents. In this
mode, the system automatically forces outside air into
the vehicle. The air conditioning compressor runs unless
the outside temperature is at or below freezing. The
air conditioning compressor operates although the
indicator light is not on. The air conditioning indicator
light turns off when defrost is selected. If the air
conditioning button is pressed while in defrost mode, the
indicator light turns on. If the button is pressed again,
the light turns off. Recirculation cannot be selected while
in the defrost mode.

Also be careful not to cover the sensor grille on the
lower right side of the climate control faceplate.
This senses the inside vehicle temperature needed
for proper regulation.
To avoid blowing cold air at start-up in cold weather,
the system delays turning on the fan until warm
air is available. The length of delay depends on the
engine coolant temperature. Turning the fan
knob overrides this delay and change the fan to a
selected speed.
If the vehicle has the remote start feature, the climate
control display initially shows “RS” in place of the
temperature to indicate the remote start has been
activated. The remote start system turns on using the
last temperature selected before the vehicle was
last turned off.
For best performance, turn the fan and mode knobs to
the AUTO position. The fan speed and air delivery
modes will change to achieve the best comfort.
If the outside air temperature is below 7°C (45°F) and
the air delivery mode knob is set to AUTO, the automatic
climate control system starts in the defrost mode to
clear the window.
The automatic climate control changes back to manual
operation by turning the vehicle on with the key.Manual Operation
The air delivery mode or fan speed can be manually
adjusted.
9(Off):Turns off the entire climate control system.
Outside air still enters the vehicle, and is directed to the
floor. This direction can be changed by adjusting the
air delivery mode position.

Engine Coolant Temperature
Warning Light
This light comes on briefly
while starting the vehicle.
If it does not, have the vehicle serviced by the
dealer/retailer. If the system is working normally the
indicator light goes off.
Notice:Driving with the engine coolant temperature
warning light on could cause the vehicle to
overheat. SeeEngine Overheating on page 6-35. The
vehicle’s engine could be damaged, and it might
not be covered by the vehicle warranty. Never drive
with the engine coolant temperature warning
light on.
The engine coolant temperature warning light comes on
when the engine has overheated.
If this happens pull over and turn off the engine as soon
as possible. SeeEngine Overheating on page 6-35
for more information.
Engine Coolant Temperature Gage
This gage shows the engine coolant temperature. If the
gage pointer moves into the red area, the light comes
on and a chime sounds, the engine is too hot. It means
that the engine coolant has overheated. SeeEngine
Overheating on page 6-35.
Tire Pressure Light
For vehicles with a tire
pressure monitoring
system, this light comes on
briefly when the engine
is started.
It provides information about tire pressures and the Tire
Pressure Monitoring System.

How to Add Automatic Transmission
Fluid
Refer to the Maintenance Schedule to determine what
kind of transmission fluid to use. SeeRecommended
Fluids and Lubricants on page 7-10.
If the fluid level is low, add only enough of the proper
fluid to bring the level into the crosshatched area on
the dipstick.
1. Remove the dipstick.
2. Using a long-neck funnel, add enough fluid at the
dipstick hole to bring it to the proper level.
It does not take much fluid, generally less than a
half pint (0.24 L). Do not overfill.
Notice:Use of the incorrect automatic transmission
uid may damage the vehicle, and the damages
may not be covered by the vehicle’s warranty.
Always use the automatic transmission uid listed
inRecommended Fluids and Lubricants on
page 7-10.
3. After adding fluid, recheck the fluid level as
described under “How to Check Automatic
Transmission Fluid” earlier in this section.
4. When the correct fluid level is obtained, reinstall the
dipstick back in all the way.
Cooling System
The cooling system allows the engine to maintain the
correct working temperature.

What to Use
{WARNING:
Adding only plain water to the cooling system can
be dangerous. Plain water, or some other liquid
such as alcohol, can boil before the proper coolant
mixture will. The vehicle’s coolant warning system
is set for the proper coolant mixture. With plain
water or the wrong mixture, the engine could get
too hot but you would not get the overheat
warning. The engine could catch fire and you or
others could be burned. Use a 50/50 mixture of
clean, drinkable water and DEX-COOL
®coolant.
Use a 50/50 mixture of clean, drinkable water and
DEX-COOL
®coolant. If using this mixture, nothing
else needs to be added. This mixture:
•Gives freezing protection down to−37°C (−34°F),
outside temperature.
•Gives boiling protection up to 129°C (265°F),
engine temperature.
•Protects against rust and corrosion.
•Will not damage aluminum parts.
•Helps keep the proper engine temperature.Notice:If an improper coolant mixture is used,
the engine could overheat and be badly damaged.
The repair cost would not be covered by the vehicle
warranty. Too much water in the mixture can freeze
and crack the engine, radiator, heater core, and
other parts.
Notice:If extra inhibitors and/or additives are used
in the vehicle’s cooling system, the vehicle could
be damaged. Use only the proper mixture of
the engine coolant listed in this manual for the
cooling system. SeeRecommended Fluids and
Lubricants on page 7-10for more information.
Checking Coolant
The vehicle must be on a level surface when checking
the coolant level.
Check to see if coolant is visible in the coolant recovery
tank. If the coolant inside the coolant recovery tank
is boiling, do not do anything else until it cools down.
If coolant is visible but the coolant level is not at or above
the FULL COLD mark, add a 50/50 mixture of clean,
drinkable water and DEX-COOL
®coolant at the coolant
recovery tank, but be sure the cooling system is cool
before this is done. See Engine Coolant for more
information.
The coolant level should be at or above the FULL COLD
mark on the coolant surge tank. If it is not, you may have
a leak in the cooling system.
6-32

Engine Overheating
The vehicle has an indicator to warn of engine
overheating.
There is an engine coolant temperature gage on
the instrument panel cluster. SeeEngine Coolant
Temperature Gage on page 4-33.
You may decide not to lift the hood when this warning
appears, but instead get service help right away.
SeeRoadside Assistance Program on page 8-7.
If you do decide to lift the hood, make sure the vehicle
is parked on a level surface.
Then check to see if the engine cooling fans are
running. If the engine is overheating, both fans should
be running. If they are not, do not continue to run
the engine and have the vehicle serviced.
Notice:Engine damage from running the engine
without coolant is not covered by the warranty.
Notice:If the engine catches re while driving
with no coolant, the vehicle can be badly damaged.
The costly repairs would not be covered by the
vehicle warranty. SeeOverheated Engine Protection
Operating Mode on page 6-37for information on
driving to a safe place in an emergency.
If Steam Is Coming From The Engine
Compartment
{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. 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 the vehicles engine is
overheated, the liquids in it can catch fire. You or
others could be badly burned. Stop the engine if
it overheats, and get out of the vehicle until the
engine is cool.
SeeOverheated Engine Protection Operating Mode
on page 6-37for information on driving to a safe
place in an emergency.
