{CAUTION:
Rust or dirt on a wheel, or on the parts to
which it is fastened, can make wheel nuts
become loose after time. The wheel could
come off and cause an accident. When
you change a wheel, remove any rust or
dirt from places where the wheel attaches
to the vehicle. In an emergency, you can
use a cloth or a paper towel to do this;
but be sure to use a scraper or wire brush
later, if needed, to get all the rust or dirt
off. SeeChanging a Flat Tire on page 426.
When It Is Time for New Tires
One way to tell when it
is time for new tires is
to check the treadwear
indicators, which will
appear when your tires
have only 1/16 inch
(1.6 mm) or less of
tread remaining.
You need a new tire if any of the following
statements are true:
You can see the indicators at three or more
places around the tire.
You can see cord or fabric showing through
the tire’s rubber.
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 cannot be repaired well because of the
size or location of the damage.

once a year and at this time the system must
be reset. Your GM Goodwrench

this work using genuine GM parts and reset
the system.

Remember to reset the oil life system whenever
the oil is changed. SeeEngine Oil Life System on
page 356for information on the Engine Oil Life
System and resetting the system.When the light or message appears, certain
services, checks, and inspections are required.

be MaintenanceI, the second service be
MaintenanceII, and that you alternate
MaintenanceIand MaintenanceIIthereafter.

required more often.
MaintenanceI— Use MaintenanceIif the light
or message comes on within 10 months since
the vehicle was purchased or MaintenanceII
