L/M(Driver and Passenger
Heated Seats): For vehicles with
heated seats, see Heated Front
Seats on page 2‑7.
Sensors
The solar sensor, located on top
of the instrument panel near the
windshield, monitors the solar heat.
The climate control system uses
the information to adjust the
temperature, fan speed,
recirculation, and air delivery mode.
Do not cover the solar sensor or the
system will not work properly.
Air Vents
Use the air outlets, located in the
center and on the side of the
instrument panel, to direct the
airflow. Use the thumbwheels
located near the center air outlets,
to open or close off the airflow.
Operation Tips
.Clear away any ice, snow,
or leaves from air inlets at the
base of the windshield that could
block the flow of air into the
vehicle.
.Keep the path under the front
seats clear of objects to help
circulate the air inside of the
vehicle more effectively.
.Use of non‐GM approved hood
deflectors can adversely affect
the performance of the system.
Check with your dealer/retailer
before adding equipment to the
outside of the vehicle.

Driving and Operating 8-31
Engine Coolant Heater
The engine coolant heater,
if available, can help in cold weather
conditions at or below−18°C (0°F)
for easier starting and better fuel
economy during engine warm-up.
Plug in the coolant heater at least
four hours before starting the
vehicle. An internal thermostat in
the plug-end of the cord will prevent
engine coolant heater operation at
temperatures above −18°C (0°F).
To Use The Engine Coolant
Heater
1. Turn off the engine.
2. Open the hood and unwrap the
electrical cord.
The electrical cord is located on
the passenger side of the engine
compartment, in front of the air
cleaner.
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
(Continued)
WARNING (Continued)
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.
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.

How to Inspect the Engine Air
Cleaner/Filter
To inspect the air cleaner/filter,
remove the filter from the vehicle
and lightly shake the filter to release
loose dust and dirt. If the filter
remains caked with dirt, a new filter
is required.
To inspect or replace the engine air
cleaner/filter:
1. Open the hood. SeeHood
on
page 9‑5
2. Locate the air filter housing on the passenger side of the engine
compartment. See Engine
Compartment Overview
on
page 9‑6
3. Remove the four air cleaner
housing cover screws.
4. Pull straight up on cover, and while holding the cover, remove
the air filter.
How to Reinstall Engine Air
Cleaner/Filter
1. Install the air cleaner into the aircleaner housing. The outer air
cleaner filter seal must be fitted
properly in the air cleaner
housing.
2. Align the air cleaner housing cover tabs to the air cleaner
housing.
3. Install the air cleaner housing cover using the four screws.

9-20 Vehicle Care
Engine Overheating
The vehicle has an indicator to warn
of engine overheating. There is an
engine coolant temperature warning
light on the vehicle's instrument
panel. SeeEngine Coolant
Temperature Gauge on page 4‑14.
The decision may be made not
to lift the hood when this warning
appears, but instead get service
help right away. See Roadside
Assistance Program on page 12‑6.
If the decision to lift the hood is
made, 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.
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. 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.
If No Steam Is Coming From
The Engine Compartment
If an engine overheat warning is
displayed but no steam can be seen
or heard, the problem may not be
too serious. Sometimes the engine
can get a little too hot when the
vehicle:
.Climbs a long hill on a hot day.
.Stops after high-speed driving.
.Idles for long periods in traffic.
.Tows a trailer.
If the overheat warning is displayed
with no sign of steam:
1. Turn the air conditioning off.
2. Turn the heater on to the highest temperature and to the highest
fan speed. Open the windows as
necessary.
3. In heavy traffic, let the engine idle in N (Neutral) while stopped.
If it is safe to do so, pull off
the road, shift to P (Park) or
N (Neutral) and let the
engine idle.

Vehicle Care 9-31
To adjust the vertical aim, do the
following:
1. Open the hood. SeeHood
on
page 9‑5for more information.
2. Locate the aim dot on the lens of the low‐beam headlamp.
3. Measure the distance from the ground to the aim dot on the
low‐beam headlamp. Record the
distance.
4. At the wall, measure from the
ground upward (A) to the
recorded distance from
Step 3 and mark it.
5. Draw or tape a horizontal line (B) on the wall the width of the
vehicle at the height of the mark
in Step 4. Notice:
Do not cover a headlamp
to improve beam cut-off when
aiming. Covering a headlamp may
cause excessive heat build-up
which may cause damage to the
headlamp.
6. Turn on the low-beam
headlamps and place a piece of
cardboard or equivalent in front
of the headlamp not being
adjusted. This allows only the
beam of light from the headlamp
being adjusted to be seen on the
flat surface.
