Remote Vehicle Start
Your vehicle may have a remote start feature.
This feature allows you to start the engine from outside
the vehicle. It may also start the vehicle’s heating or
air conditioning systems. When you start your vehicle
using the remote start feature, the climate control
system will come on and adjust the interior to the
temperature settings that you left it set to when
you turned the vehicle off.
Laws in some communities may restrict the use of
remote starters. For example, some laws may require
a person using remote start to have the vehicle in
view when doing so. Check local regulations for
any requirements on remote starting of vehicles.
Do not use the remote start feature if your vehicle is low
on fuel. Your vehicle may run out of fuel.
The remote start feature provides two separate starts
per ignition cycle, each with 10 minutes of engine
running time.
After your vehicle’s engine has been started two times
using the remote vehicle start button, the vehicle’s
ignition switch must be turned to ON/RUN and then
back to LOCK/OFF using the key before the remote start
procedure can be used again. SeeIgnition Positions on
page 2-21for information regarding the ignition positions
on your vehicle.If your vehicle has the remote start feature, the RKE
transmitter functions will have an increased range
of operation. However, the range may be less while
the vehicle is running.
There are other conditions which can affect the
performance of the transmitter, seeRemote Keyless
Entry (RKE) System on page 2-3for 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, do
the following:
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 running, to extend the time by 10 minutes for the
engine to continue to run.
After entering the vehicle after a remote start, insert and
turn the key to ON/RUN to drive the vehicle.

Climate Controls
Climate Control System
The heating, cooling, and ventilation for the vehicle can
be controlled with this system.
A. Air Delivery Mode
Control
B. Fan Control
C. Temperature ControlD. Air Conditioning
E. Rear Window
Defogger
F. RecirculationTo change the current mode, select one of the following:
9(Off):Turn the fan control to this position to turn
the fan off.
Temperature Control:Turn clockwise or
counterclockwise to increase or decrease the
temperature.
9(Fan Control):Turn clockwise or counterclockwise
to increase or decrease the fan speed. In any setting
other than off, the fan will run continuously with
the ignition on. The fan must be turned on to run the air
conditioning compressor.
Air Delivery Mode Control:Turn clockwise or
counterclockwise to change the direction of the
airow inside the vehicle.
Select from the following modes:
H(Vent):Air is directed to the instrument panel
outlets.
)(Bi-Level):Air is divided between the instrument
panel outlets and the oor outlets. Cooler air is directed
to the upper outlets and warmer air to the oor outlets. Vehicles with Air Conditioning shown,
without Air Conditioning similar
3-18

6(Floor):Air is directed to the oor outlets, with
some air directed to the windshield and side windows.
-(Defog):This mode clears the windows of fog
or moisture. Air is directed to the windshield, side
window, and oor outlets. To defog the windows faster,
turn the temperature control knob clockwise to the
warmest setting. In this mode, the system runs the
air conditioning compressor.
0(Defrost):This mode removes fog or frost from the
windshield more quickly. Air is directed to the windshield,
with some air directed to the side window outlets and
the oor outlets. To defrost the windows faster, turn
the temperature control knob clockwise to the warmest
setting. In this mode, the system runs the air conditioning
compressor.
For best results, clear all snow and ice from the
windshield before defrosting.
#(Air Conditioning):For vehicles with air
conditioning, press this button to turn the air conditioning
system on or off. An indicator light comes on to show
that the air conditioning is on.
On hot days, open the windows to let hot inside air
escape; then close them. This helps to reduce the time
it takes for the vehicle to cool down. It also helps the
system to operate more efficiently.For quick cool down on hot days:
1. Select the
Hmode.
2. Select the
hmode.
3. Select
#.
4. Select the coolest temperature.
5. Select the highest fan speed.
Using these settings together for long periods of time
may cause the air inside of the vehicle to become
too dry. To prevent this from happening, after the air
in the vehicle has cooled, turn off the recirculation
by pressing the button again.
The air conditioning system removes moisture from
the air, so a small amount of water might drip under
the vehicle while idling or after turning off the engine.
This is normal.
The air conditioning compressor cannot be turned on
when the fan is off.
h(Recirculation):Press to turn the recirculation
mode on. An indicator light comes on to show that
recirculation is on.
This mode recirculates and helps to quickly cool the
air inside the vehicle. It can be used to help prevent
outside air and odors from entering the vehicle.
3-19

The air conditioning compressor also comes on.
Recirculation is not available for oor, defog and
defrost modes. If recirculation is selected in any of
these modes, the recirculate indicator light ashes
ve times and outside air will be delivered. Operation
in this mode during periods of high humidity and cool
outside temperatures may result in increased window
fogging. If window fogging is experienced, select the
defrost mode.
Outside Air:This mode allows outside air to circulate
through the vehicle. This mode is automatically active
if recirculate is not selected. There is no button for
outside air.
Rear Window Defogger
The rear window defogger uses a warming grid to
remove fog from the rear window.
The rear window defogger only works when the ignition
is in ON/RUN.
<(Rear):Press to turn the rear window defogger
on or off. Be sure to clear as much snow from the rear
window as possible. An indicator light comes on to show
that the rear window defogger is on.
The rear window defogger turns off about 15 minutes
after the button is pressed. If turned on again, the
defogger only runs for about seven minutes beforeturning off. If the vehicle is moving faster than 50 mph
(80 kph), the rear defogger will stay on. The defogger
can also be turned off by turning off the engine.
Notice:Do not use anything sharp on the inside
of the rear window. If you do, you could cut or
damage the warming grid, and the repairs would
not be covered by the vehicle warranty. Do not
attach a temporary vehicle license, tape, a decal
or anything similar to the defogger grid.
Outlet Adjustment
Use the thumbwheels located next to and below the air
outlets to change the direction of the airow and to
open and close the outlets.
Operation Tips

Clear away any ice, snow or leaves from the air
inlets at the base of the windshield that may
block the ow of air into the vehicle.
Use of non-GM approved hood deectors may
adversely affect the performance of the system.
Keep the path under the front seats clear of objects
to help circulate the air inside of the vehicle more
effectively.

Turn Signals When Towing a Trailer
The arrows on the instrument panel ash whenever
signaling a turn or lane change. Properly hooked up, the
trailer lamps also ash, telling other drivers the vehicle
is turning, changing lanes or stopping.
When towing a trailer, the arrows on the instrument panel
ash for turns even if the bulbs on the trailer are burned
out. For this reason you may think other drivers are
seeing the signal when they are not. It is important to
check occasionally to be sure the trailer bulbs are still
working.
Driving on Grades
Notice:Do not tow on steep continuous grades
exceeding 6 miles (9.6 km). Extended, higher than
normal engine and transmission temperatures may
result and damage the vehicle. Frequent stops are
very important to allow the engine and transmission
to cool.
Reduce speed and shift to a lower gearbeforestarting
down a long or steep downgrade. If the transmission is
not shifted down, the brakes might have to be used so
much that they would get hot and no longer work well.On a long uphill grade, shift down and reduce the
vehicle’s speed to around 45 mph (70 km/h) to reduce
the possibility of the engine and the transmission
overheating.
Vehicles can tow in D (Drive). Shift the transmission to
a lower gear if the transmission shifts too often under
heavy loads and/or hilly conditions.
Pay attention to the engine coolant gage. If the indicator
is in the red area, turn off the air conditioning to reduce
engine load. SeeEngine Overheating on page 5-27.
When towing under severe conditions such as hot
ambient temperatures or steep grades, the vehicle may
experience more transmission shifting. A COOLING
MODE ON message may also appear in the DIC. This
alerts the driver that the shifting mode is in progress
and is aiding engine cooling. SeeDIC Warnings and
Messages on page 3-42DIC Warnings and Messages
for more information.
4-36

(C) Aspect Ratio:A two-digit number that
indicates the tire height-to-width measurements.
For example, if the tire size aspect ratio is 60, as
shown in item C of the illustration, it would mean
that the tire’s sidewall is 60 percent as high as
it is wide.
(D) Construction Code
:A letter code is used to
indicate the type of ply construction in the tire. The
letter R means radial ply construction; the letter D
means diagonal or bias ply construction; and the
letter B means belted-bias ply construction.
(E) Rim Diameter
:Diameter of the wheel in
inches.
(F) Service Description
:These characters
represent the load index and speed rating of the
tire. The load index represents the load carry
capacity a tire is certied to carry. The speed rating
is the maximum speed a tire is certied to carry
a load.
Tire Terminology and Denitions
Air Pressure:The amount of air inside the tire
pressing outward on each square inch of the tire.
Air pressure is expressed in pounds per square
inch (psi) or kilopascal (kPa).
Accessory Weight
:This means the combined
weight of optional accessories. Some examples of
optional accessories are, automatic transmission,
power steering, power brakes, power windows,
power seats, and air conditioning.
Aspect Ratio
:The relationship of a tire’s height
to its width.
Belt
:A rubber coated layer of cords that is located
between the plies and the tread. Cords may be
made from steel or other reinforcing materials.
Bead
:The tire bead contains steel wires wrapped
by steel cords that hold the tire onto the rim.
Bias Ply Tire
:A pneumatic tire in which the plies
are laid at alternate angles less than 90 degrees
to the centerline of the tread.
Cold Tire Pressure
:The amount of air pressure in
a tire, measured in pounds per square inch (psi) or
kilopascals (kPa) before a tire has built up heat
from driving. SeeInflation - Tire Pressure on
page 5-55.
