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.

carbon monoxide (CO), which
cannot be seen or smelled. It can
cause unconsciousness and even
death.
If the vehicle is stuck in snow:
.Clear snow from the base ofthe vehicle, especially anyblocking the exhaust pipe.
.Open a window about 5 cm(2 in) on the vehicle sidethat is away from the wind,to bring in fresh air.
.Fully open the air outlets onor under the instrumentpanel.

vehicle itself. Get acquainted withthe handling and braking of the rigbefore setting out for the open road.
The structure, tires, and brakes ofthe trailer must be rated to carry theload. Inadequate trailer equipmentcan cause the combination tooperate in an unexpected or unsafemanner.
Before starting, check all trailer hitchparts and attachments, safetychains, electrical connectors, lamps,tires, and mirrors. Get familiar withthe handling and braking of the rig.If the trailer has electric brakes, startthe combination moving and thenapply the trailer brake controller byhand to be sure the brakes work.
During the trip, check occasionallyto be sure that the load is secureand the lamps and any trailerbrakes still work.
Following Distance
Stay at least twice as far behind thevehicle ahead as you would whendriving the vehicle without a trailer.This can help to avoid heavybraking and sudden turns.

270 Vehicle Care
{Warning
If different sized wheels are used,
there may not be an acceptable
level of performance and safety if
tires not recommended for those
wheels are selected. This
increases the chance of a crash
and serious injury. Only use GM
specific wheel and tire systems
developed for the vehicle, and
have them properly installed by a
GM certified technician.
SeeBuying New Tires0268andAccessories andModifications0216.
Uniform Tire Quality
Grading
The following information relates
to the system developed by the
United States National Highway
Traffic Safety Administration
(NHTSA), which grades tires by
treadwear, traction, and
temperature performance. This
applies only to vehicles sold in
the United States. The grades
are molded on the sidewalls of
most passenger car tires. The
Uniform Tire Quality Grading
(UTQG) system does not apply
to deep tread, winter tires,
compact spare tires, tires with
nominal rim diameters of
10 to 12 inches (25 to 30 cm),
or to some limited-production
tires.
While the tires available on
General Motors passenger cars
and light trucks may vary with
respect to these grades, they
must also conform to federal
safety requirements and
additional General Motors Tire
Performance Criteria (TPC)
standards.
Quality grades can be found
where applicable on the tire
sidewall between tread shoulder
and maximum section width. For
example:
Treadwear 200 Traction AATemperature A
All Passenger Car Tires Must
Conform to Federal Safety
Requirements In Addition To
These Grades.
Treadwear
The treadwear grade is a
comparative rating based on the
wear rate of the tire when tested
under controlled conditions on a
specified government test
course. For example, a tire
graded 150 would wear one and
one-half (1Ω) times as well on
the government course as a tire
graded 100. The relative
performance of tires depends
upon the actual conditions of
their use, however, and may
depart significantly from the
norm due to variations in driving
habits, service practices and
differences in road
characteristics and climate.
