Climate Controls
Climate Control System
With this system you can control the heating, cooling
and ventilation for your vehicle.
9(Fan):Turn the left knob 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 on in order for
the air conditioning compressor to run.To change the current mode, select one of the following
from the middle knob:
E(Vent):This mode directs air to the instrument
panel outlets.
((Bi-Level):This mode directs about half of the air
to the instrument panel outlets, and then directs the
remaining air to the floor outlets.
5(Floor):This mode directs most of the air to the
floor outlets. Some of the air will also be directed to the
windshield, instrument panel side outlets, and the
rear outlets. Be sure to keep the area under the front
seats clear to allow the flow of air to the rear
compartment.
The middle knob can also be used to select the defog
and defrost modes. Information on defogging and
defrosting can be found later in this section.
Temperature Control:Turn the right knob clockwise or
counterclockwise to manually increase or decrease
the temperature inside your vehicle. Turn the knob to the
blue area to get cool air and to the red area to get
warm air. Uplevel shown, Base similar

Outlet Adjustment
Use the lever located in the center of each outlet to
change the direction of the airflow. For four-door models,
use the thumbwheel located next to the outlets to turn
them on and off. For five-door models, use the
thumbwheel located below the outlets to turn them
on and off.
Operation Tips
•
Clear away any ice, snow or leaves from the air
inlets at the base of the windshield that may
block the flow of air into your vehicle.
•Use of non-GM approved hood deflectors 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 your vehicle more
effectively.
Passenger Compartment Air Filter
Your vehicle may have a passenger compartment
air filter. It is located on the passenger side under the
glove box.
The filter traps most of the pollen from air entering the
module. Like your engine’s air cleaner/filter, it may need
to be changed periodically.

{CAUTION:
Things you put inside your vehicle can strike
and injure people in a sudden stop or turn, or
in a crash.
Put things in the trunk of your vehicle. In a
trunk, put them as far forward as you can.
Try to spread the weight evenly.
Never stack heavier things, like suitcases,
inside the vehicle so that some of them
are above the tops of the seats.
Do not leave an unsecured child restraint
in your vehicle.
When you carry something inside the
vehicle, secure it whenever you can.
Do not leave a seat folded down unless
you need to.
Towing
Towing Your Vehicle
Consult your dealer or a professional towing service if
you need to have your disabled vehicle towed. See
Roadside Assistance Program on page 7-6.
If you want to tow your vehicle behind another vehicle
for recreational purposes (such as behind a motorhome),
see “Recreational Vehicle Towing” following.
Recreational Vehicle Towing
Recreational vehicle towing means towing your vehicle
behind another vehicle, such as behind a motorhome.
The two most common types of recreational vehicle
towing are known as “dinghy towing” (towing your
vehicle with all four wheels on the ground) and “dolly
towing” (towing your vehicle with two wheels on
the ground and two wheels up on a device known
as a “dolly”).
With the proper preparation and equipment, many
vehicles can be towed in these ways. See “Dinghy
Towing” and “Dolly Towing,” following.

Tire Size
The following illustration shows an example of a typical
passenger car tire size.
(A) Passenger (P-Metric) Tire:The United States
version of a metric tire sizing system. The letter P as the
first character in the tire size means a passenger
vehicle tire engineered to standards set by the U. S.
Tire and Rim Association.
(B) Tire Width:The three-digit number indicates the
tire section width in millimeters from sidewall to sidewall.
(C) Aspect Ratio:A two-digit number that indicates
the tire height-to-width measurements. For example, if
the tire size aspect ratio is 70, as shown in item C of the
illustration, it would mean that the tire’s sidewall is
70% 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 range and the speed rating of a tire. The
load range represents the load carry capacity a tire is
certified to carry. The speed rating is the maximum
speed a tire is certified to carry a load. Speed ratings
range from A to Z.
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.
