Outlet Adjustment
Rotate the instrument panel outlets and move the
louvers on the outlets to change the direction and
amount of airflow inside the vehicle.
Operation Tips
•Clear away any ice, snow or leaves from the air
inlets at the base of the windshield that can
block the flow of air into the vehicle.
•Use of non-GM approved hood deflectors can
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.
•When an objectionable odor outside the vehicle is
encountered, use the recirculation mode, with the
temperature knob at a comfortable setting to prevent
the odor from entering the vehicle through the
ventilation system. This can be helpful when driving
through a long tunnel with poor ventilation.
However, extended usage of this mode in cold or
cool weather can cause window fogging.
Warning Lights, Gages, and
Indicators
Warning lights and gages can signal that something is
wrong before it becomes serious enough to cause
an expensive repair or replacement. Paying attention to
the warning lights and gages could prevent injury.
Warning lights come on when there might be or there is
a problem with one of the vehicle’s functions. Some
warning lights come on briefly when the engine is started
to indicate they are working.
Gages can indicate when there might be or there is a
problem with one of the vehicle’s functions. Often gages
and warning lights work together to indicate a problem
with the vehicle.
When one of the warning lights comes on and stays on
while driving, or when one of the gages shows there
could be a problem, check the section that explains what
to do. Follow this manual’s advice. Waiting to do
repairs can be costly and even dangerous.

If things like suitcases, tools, packages, or
anything else are put inside the vehicle, they
will go as fast as the vehicle goes. If you have
to stop or turn quickly, or if there is a crash, they
will keep going.
{WARNING:
Things you put inside the vehicle can strike
and injure people in a sudden stop or turn,
or in a crash.
•Put things in the cargo area of the
vehicle. In the cargo area, 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 the 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
To avoid damage, the disabled vehicle should be towed
with all four wheels off the ground. Consult your dealer/
retailer or a professional towing service if the disabled
vehicle must be towed. SeeRoadside Assistance
Program on page 8-7.
To tow the 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 the vehicle
behind another vehicle – such as behind a motorhome.
The two most common types of recreational vehicle
towing are known as dinghy towing and dolly towing.
Dinghy towing is towing the vehicle with all four wheels
on the ground. Dolly towing is towing the vehicle with
two wheels on the ground and two wheels up on a device
known as a dolly.

(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 certified to carry. The speed
rating is the maximum speed a tire is certified
to carry a load.
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.
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.
