Malfunction Indicator
(SERVICE ENGINE SOON) Lamp
The Malfunction Indicator (SERVICE ENGINE SOON) Lamp on your
instrument panel 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.
Secondary Air hjection Reaction (AIR) System
You may have this system. It has a control valve that will direct air to where
it is needed. If the AIR system needs service, your Malfunction Indicator
(SERVICE ENGINE SOON) Lamp on your instrument panel will come on.

The Certification/Tire
label is found on the
rear edge of the
driver’s door or
in the
Incomplete Vehicle
Document
in the cab.
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 Certification/Tire 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 GAWR for either the front
or rear axle.
And,
if you do have a heavy load, you should spread it out.

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 CertificatiodTire label. Make certain that all wheel nuts are
properly tightened. See “Wheel
Nut Torque” in the Index.
A CAUTION:
Rust or dirt on a wheel, or on the parts to which it is fastened,
When It’s Time for New Tires
TREAD WEAR
INDICATORS
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:
0 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.
The tire has a bump, bulge or split.
The tire has a puncture, cut, or other damage that can’t be repaired well
because
of the size or location of the damage.

Dual Tire Rotation
n
Use one of these
patterns if you have
the same tire sizes and
load ranges on
the
front and rear.
Use
this pattern if
your front and rear
tires are different sizes
or load ranges. The
dual rear tires are
rotated
as a pair and
the inside rear tires
become the outside
rear tires.
When you install dual wheels, be sure
the vent holes in the wheels are lined
UP.

Dual lire Operation
If your vehicle has dual rear wheels, the outer tire will usually wear faster
than the inner tire. Your tires will wear more evenly and last longer
if you
rotate the tires periodically. If you’re going to be doing a lot of driving on
high-crown roads,
you can reduce tire wear by adding 5 psi (35 kPa) to the
tire pressure in the outer tires. Be sure to return to the recommended
pressures when
no longer driving under those conditions.
Buying New Tires
To find out what kind and size of tires you need, look at the
CertificationRire 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).
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.

NOTICE:
The wrong wheel can also cause problems with bearing life,
brake cooling, speedometer/odometer calibration, headlight aim,
bumper height, vehicle ground clearance, and tire or tire chain
clearance to the body and chassis.
Used Replacement Wheels
Tire Chains
NOTICE:
If your vehicle has dual wheels or LT26Y75R16 size tires, don’t
use tire chains; they can damage your vehicle.
If you don’t have
dual wheels or
if you have a tire size other than LT265/75R16,
use tire chains only where legal and only when you must. Use
only SAE Class “S” type chains that are the proper size for your
tires. Install them on the tires of the rear axle. Tighten them as
tightly
as possible with the ends securely fastened. Drive slowly
and follow the chain manufacturer’s instructions.
If you can
hear the chains contacting your vehicle, stop and retighten them.
If the contact continues, slow down until it stops. Driving too
fast with chains on will damage your vehicle.

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, tlush 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.
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.
This applies
only to materials manufactured and sold by General Motors.
Bodies, body conversions or equipment
not made or sold by General Motors
are not covered.
