This knob is located below
the main climate-control
system on the instrument
panel switchbank. Use
this knob to adjust the fan
speed for the rear-seat
passengers, from the
front-seating area.
These controls are overhead, on the control panel located
behind the front seats. A rear-seat passenger can use
these controls to personally adjust the temperature and
the fan speed for the rear-seating area.The fan knob located on the switchbank must be turned
to R (Rear) to allow the rear-seat passengers to use
the controls located on the control panel in the
rear-seating area. If this fan knob is not in R when the
FAN or TEMP button is pressed, the rear control
panel will show DISABLED.
Directing the Air¯ow
To direct the air¯ow to the rear-seating area, use the
right knob located on the main climate-control panel.
·Select vent or bi-level mode to direct air to the
rear of the vehicle through the overhead outlets.
·Select ¯oor, defog or defrost mode to direct air to
the rear of the vehicle through the ¯oor outlets.
Generally the upper outlets are used for air conditioning
and the ¯oor outlets are used for heating.

control:
9(Fan):Turn the fan knob on the rear fan control
located below the main climate-control system on
the switchbank to numeral 1, 2, or 3 to increase or
decrease air¯ow to the rear-seating area. Turn the fan
knob on the rear fan control to 0 to turn off the fan.
If a rear-seat passenger is adjusting the fan speed, use
the following control:
FAN:Press the FAN button on the rear control panel.
The display will show the current setting. Press the
left and right arrow buttons to cycle through the available

Setting the Temperature
If the driver is adjusting the temperature, do the
following:
To increase or decrease the temperature for the entire
vehicle, use the temperature controls located on the
main climate-control panel.If using the main climate-control panel, then the
air-conditioning system must be on to direct cooled air to
the rear of the vehicle. If it is not on, then the temperature
in the rear of the vehicle will remain at cabin temperature.
If a rear-seat passenger is adjusting the temperature,
do the following:
Press the TEMP button on the rear control panel. Use the
left arrow button to make the air cooler. Use the right
arrow button to make the air warmer.
Rear Air Outlets
To increase air¯ow through the rear ¯oor outlets, place
the left bucket seat in the second row in the forward
position. For more information, see
Rear Seat Operation
on page 1-8.
The outlet behind the left rear seat is the cold air return
outlet. Be sure to keep it free from obstructions.
Also, keep the area around the base of the center
instrument panel console, between and under the front
seats, free of objects that could also obstruct air¯ow
to the rear-seating area.

(A) Light Truck (LT-Metric) Tire:The United States
version of a metric tire sizing system. The letter ªLTº
as the ®rst two characters in the tire size means a light
truck 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 ª75,º as shown in item ªCº
of the illustration, it would mean that the tire's sidewall
is 75% 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
ªRº means radial ply construction; the letter ªDº means
diagonal or bias ply construction; and the letter ªBº
means belted-bias ply construction.
(E) Rim Diameter:Diameter of the wheel in inches.
(F) Service Description:The service description
indicates the load range and speed rating of a tire.
The load index can range from 1 to 279. Speed ratings
range from ªAº to ªZº. The light truck tire size example
above shows dual or single tire con®gurations.Tire Terminology and De®nitions
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. Light Truck (LT-Metric) Tire

(c)Visually inspect hoses and have them replaced if they
are cracked, swollen or deteriorated. Inspect all pipes,
®ttings and clamps; replace with genuine GM parts as
needed. To help ensure proper operation, a pressure test
of the cooling system and pressure cap and cleaning the
outside of the radiator and air conditioning condenser is
recommended at least once a year.
(d)Visually inspect wiper blades for wear or cracking.
Replace blade inserts that appear worn or damaged
or that streak or miss areas of the windshield.
(e)Make sure the safety belt reminder light and all your
belts, buckles, latch plates, retractors and anchorages
are working properly. Look for any other loose or
damaged safety belt system parts. If you see anything
that might keep a safety belt system from doing its
job, have it repaired. Have any torn or frayed safety belts
replaced. Also look for any opened or broken air bag
coverings, and have them repaired or replaced. (The air
bag system does not need regular maintenance.)
(f)Lubricate all key lock cylinders, hood latch
assemblies, secondary latches, pivots, spring anchor
and release pawl, hood and door hinges, rear folding
seats, liftgate hinges, fuel door hinge, power sliding door
cable and sliding door track(s). More frequent lubrication
may be required when exposed to a corrosive
environment. Applying silicone grease on weatherstrips
with a clean cloth will make them last longer, seal
better and not stick or squeak.
(g)If you drive regularly under dusty conditions, the
®lter may require replacement more often.
(h)Change automatic transaxle ¯uid and ®lter if the
vehicle is mainly driven under one or more of these
conditions:
þIn heavy city traffic where the outside temperature
regularly reaches 90ÉF (32ÉC) or higher.
þIn hilly or mountainous terrain.
þWhen doing frequent trailer towing.
þUses such as found in taxi, police or delivery
service.
(i)Drain, ¯ush and re®ll cooling system. See Engine
Coolant on page 5-22for what to use. Inspect hoses.
Clean radiator, condenser, pressure cap and ®ller neck.
Pressure test the cooling system and pressure cap.
(j)
Check system for interference or binding and
for damaged or missing parts. Replace parts as needed.
Replace any components that have high effort or
excessive wear. Do not lubricate accelerator or cruise
control cables.
(k)A ¯uid loss in any vehicle system could indicate a
problem. Have the system inspected and repaired
and the ¯uid level checked. Add ¯uid if needed.
