(SERVICE ENGINE SOON )
This light on your instrument cluster lets you know when your emission
system needs service. The light will come on briefly when you start your
engine to let you know that the system is working. If it does not come on
when you start your engine, or if it comes
on and stays on while you’re
driving, your system may need service. Your vehicle should still be
driveable, but you should have your system serviced right away.
Loading Your Vehicle
The Certificationire
label is found on the
rear edge of the
driver’s door. The
label shows the size of
your original tires and
the inflation pressures
needed to obtain the
gross weight capacity
of your vehicle.
This is called the GVWR (Gross Vehicle Weight Rating). The GVWR
includes the weight of the vehicle, all occupants, fuel and cargo.
The CertificatiodTire label
also tells you the maximum weights for the
front and rear axles, called Gross Axle Weight Rating (GAWR). To find out
the actual loads on your front and rear axles, you need
to go to a weigh
station and weigh your vehicle. Your dealer can help you with this. Be sure
to spread out your load equally on both sides of the centerline.
Never exceed
the GVWR for your vehicle, or the Gross Axle Weight Rating
(GAWR) for either the front or rear axle.

To make your tires last longer, have them inspected and rotated at the
mileages recommended
in the Maintenance Schedule. See “Scheduled
Maintenance Services” in the Index.
Use this rotation
pattern.
Do not
include compact spare
tire
in rotation.
If your vehicle has front tires
with different load ratings or tread designs
(such as all season
vs. on/off road) than the rear tires, don’t rotate your tires
front to rear.
After the tires have been rotated, adjust the front and rear inflation pressure
as shown on the CertificationEire label. Make certain that all wheel nuts are
properly tightened. See “Wheel
Nut Torque” in the Index.

Downloaded from www.Manualslib.com manuals search engine When It’s Time for New Tires
a
One way to tell when
it’s time for new tires
is to check the
treadwear indicators,
which
will appear
when your tires have
only
2/32 inch
(1.6 mm) or less of
tread remaining.
You need a new tire
if
You can see the indicators at three or more places around the tire.
0 You can see cord or fabric showing through the tire’s rubber.
0 The tread or sidewall is cracked, cut or snagged deep enough to show
cord or fabric.
0 The tire has a bump, bulge or split.
0 The tire has a puncture, cut, or other damage that can’t be repaired well
because of the size or location of the damage.
Buying New Tires
To find out what kind and size of tires you need, look at the
CertificationEire label.
The tires installed on your vehicle
when it was new had a Tire Performance
Criteria Specification (TPC Spec) number on each tire’s sidewall. When you
get new tires, get ones
with that same TPC Spec number. That way, your
vehicle will continue to have tires that are designed
to give proper
endurance, handling, speed rating, traction, ride and other things during
normal service on your vehicle.
If your tires have an all-season tread
design,
the TPC number will be followed by a “MS” (for mud and snow).

Downloaded from www.Manualslib.com manuals search engine If you ever replace your tires with those not having a TPC Spec number,
make sure they are the same size, load range, speed rating and construction
type (bias, bias-belted
or radial) as your original tires.

Uniform Tire Quality Grading
The following information relates to the system developed by the United
States National Highway Traffic Safety Administration which grades tires
by treadwear, traction and temperature performance. (This applies only to
vehicles sold
in the United States.)
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 a half (1 1/2)
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.
Traction - A, 8, C
The traction grades, from highest to lowest are: A, B, and C. They represent
the tire’s ability to stop on wet pavement as measured under controlled
conditions on specified government test surfaces
of asphalt and concrete. A
tire marked C may have poor traction performance.
Warning: The traction grade assigned to this tire is based on braking
(straight-ahead) traction tests and does not include cornering (turning)
traction.

Downloaded from www.Manualslib.com manuals search engine Finish Damage
Any stone chips, fractures or deep scratches in the finish should be repaired
right away. Bare metal will corrode quickly and
may develop into a major
repair expense.
Minor chips and scratches can be repaired with touch-up materials available
from your dealer or other service outlets. Larger areas
of finish damage can
be corrected in your dealer’s body and paint shop.
Underbody Maintenance
Chemicals used for ice and snow removal and dust control can collect on
the underbody. If these are not removed, accelerated
corrosion (rust) can
occur on the underbody parts such as fuel lines, frame, floor pan, and
exhaust system even though they have corrosion protection.
At least every spring, flush these materials from the underbody with plain
water. Clean any areas where mud and other debris can collect. Dirt packed
in closed areas of the frame should be loosened before being flushed. Your
dealer or
an underbody vehicle washing system can do this for you.
Fiberglass Springs
I NOTICE:
Don’t use corrosive or acidic cleaning agents, engine degreas\
ers,
aluminum cleaning agents
or other harsh solvents to clean
fiberglass springs; they’ll damage the springs.
Chemical Paint Spotting
Some weather and atmospheric conditions can create a chemical fallout.
Airborne pollutants can fall upon and attack painted surfaces on your
vehicle. This damage can take two forms: blotchy, ringlet-shaped
discolorations, and small irregular dark spots etched into the paint surface.
Although no defect in the paint job causes this,
GM will repair, at no charge
to the owner, the surfaces
of new vehicles damaged by this fallout condition
within
12 months or 12,000 miles (20 000 km) of purchase, whichever
comes first.

*I1 IlI\lI /I1 IIlIlIIl1II- o TESTVNXX3XXQ09696 0
This is the legal identifier for your vehicle. It appears on a plate in the front
corner of the instrument panel, on the driver’s side. You can see
it if you
look through the windshield from outside your vehicle. The VIN also
appears on the Vehicle Certification and Service Parts labels and the
certificates of title and registration.

Be sure that this label is not removed from the vehicle.
Add-on Electrical Equipment
NOTICE:
Don’t add anything electrical to your vehicle unless you che\
ck
with your dealer first. Some electrical equipment can damage
your vehicle and the damage wouldn’t be covered by your
warranty. Some add-on electrical equipment can keep other
components from working
as they should.
Your vehicle has a facial air bag system. Before attempting to add anything
electrical to your vehicle, see “Servicing Your Facial Air Bag-Equipped
Vehicle” in the Index.
