2:Air is directed to the flooroutlets.
Be sure to keep the area under thefront seats clear of any objects sothat the air inside of the vehicle cancirculate effectively.
For information on how to use themain climate control system, seeClimate Control Systems0158.Forinformation on ventilation, seeAirVents0163.
Air Vents
Use the outlets located near thecenter and on the sides of theinstrument panel to change thedirection of airflow.
Operation Tips
.Clear away any ice, snow orleaves from the air inlets at thebase of the windshield that mayblock the flow of air into thevehicle.
.Use of non-GM approved hooddeflectors may adversely affectthe performance of the system.
.Keep the path under the frontseats clear of objects to helpcirculate the air inside of thevehicle more effectively.
Maintenance
Service
All vehicles have a label underhoodthat identifies the refrigerant used inthe vehicle. The refrigerant systemshould only be serviced by trainedand certified technicians. The airconditioning evaporator shouldnever be repaired or replaced byone from a salvage vehicle.It should only be replaced by a newevaporator to ensure proper andsafe operation.
During service, all refrigerantsshould be reclaimed with properequipment. Venting refrigerantsdirectly to the atmosphere is harmfulto the environment and may alsocreate unsafe conditions based oninhalation, combustion, frostbite,or other health-based concerns.

Light Truck (LT-Metric) Tire
(1) Light Truck (LT-Metric)
Tire:The United States version
of a metric tire sizing system.
The letters LT as the first two
characters in the tire size mean
alighttrucktireengineeredto
standards set by the U.S. Tire
and Rim Association.
(2) Tire Width:The three-digit
number indicates the tire section
width in millimeters from
sidewall to sidewall.
(3) Aspect Ratio:Atwo-digit
number that indicates the tire
height-to-width measurements.
For example, if the tire size
aspect ratio is 75, as shown in
item 3 of the light truck
(LT-Metric) tire illustration, it
would mean that the tire's
sidewall is 75 percent as high as
it is wide.
(4) Construction Code:Aletter
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.
(5) Rim Diameter:Diameter of
the wheel in inches.
(6) Load Range:Load Range.
(7) Service Description:The
service description indicates the
load index and speed rating of a
tire. If two numbers are given as
in the example, 120/116, then
this represents the load index for
single versus dual wheel usage
(single/dual). The speed rating is
the maximum speed a tire is
certified to carry a load. This
does not apply to Goodyear

Tire Terminology and
Definitions
Air Pressure:The amount of
air inside the tire pressing
outward on each square inch of
the tire. Air pressure is
expressed in kPa (kilopascal)
or psi (pounds per square inch).
Accessory Weight:The
combined weight of optional
accessories. Some examples of
optional accessories are
automatic transmission, power
windows, power seats, and air
conditioning.
Aspect Ratio:The relationship
of a tire's height to its width.
