Adjust the front and rear tires
to the recommended inflation
pressure on the Tire and
Loading Information label after
the tires have been rotated.
SeeTire Pressure on
page 10‑62 andVehicle Load
Limits on page 9‑14.
Reset the Tire Pressure
Monitor System. See Tire
Pressure Monitor Operation on
page 10‑66.
Check that all wheel nuts are
properly tightened. See “Wheel
Nut Torque” underCapacities
and Specifications on
page 12‑2.{WARNING
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 changing a wheel, remove
any rust or dirt from places where
the wheel attaches to the vehicle.
In an emergency, a cloth or a
paper towel can be used;
however, use a scraper or wire
brush later to remove all rust
or dirt.
Lightly coat the center of the
wheel hub with wheel bearing
grease after a wheel change or
tire rotation to prevent corrosion
or rust build-up. Do not get
grease on the flat wheel
mounting surface or on the
wheel nuts or bolts.
When It Is Time for
New Tires
Factors such as maintenance,
temperatures, driving speeds,
vehicle loading, and road conditions
affect the wear rate of the tires.
Treadwear indicators are one way
to tell when it is time for new tires.
Treadwear indicators appear when
the tires have only 1.6 mm (1/16 in)
or less of tread remaining. See Tire
Inspection on page 10‑68 andTire
Rotation on page 10‑68 for more
information.

10-70 Vehicle Care
The rubber in tires ages over time.
This also applies for the spare tire,
if the vehicle has one, even if it is
never used. Multiple conditions
including temperatures, loading
conditions, and inflation pressure
maintenance affect how fast aging
takes place. Tires will typically
need to be replaced due to wear
before they may need to be
replaced due to age. Consult the tire
manufacturer for more information
on when tires should be replaced.
Vehicle Storage
Tires age when stored normally
mounted on a parked vehicle.
Park a vehicle that will be stored for
at least a month in a cool, dry, clean
area away from direct sunlight to
slow aging. This area should be
free of grease, gasoline, or other
substances that can deteriorate
rubber.Parking for an extended period can
cause flat spots on the tires that
may result in vibrations while
driving. When storing a vehicle for
at least a month, remove the tires
or raise the vehicle to reduce the
weight from the tires.
Buying New Tires
GM has developed and matched
specific tires for the vehicle.
The original equipment tires
installed were designed to meet
General Motors Tire Performance
Criteria Specification (TPC Spec)
system rating. When replacement
tires are needed, GM strongly
recommends buying tires with the
same TPC Spec rating.
GM's exclusive TPC Spec system
considers over a dozen critical
specifications that impact the
overall performance of the
vehicle, including brake systemperformance, ride and handling,
traction control, and tire pressure
monitoring performance. GM's TPC
Spec number is molded onto the
tire's sidewall near the tire size.
If the tires have an all‐season tread
design, the TPC Spec number will
be followed by MS for mud and
snow. See
Tire Sidewall Labeling on
page 10‑58, for additional
information.
GM recommends replacing all the
tires at the same time. Uniform
tread depth on all tires will help to
maintain the performance of the
vehicle. Braking and handling
performance may be adversely
affected if all the tires are not
replaced at the same time.
See Tire Inspection on page 10‑68
and Tire Rotation on page 10‑68.

.Check the tire inflation
pressures. See Tire Pressure on
page 10‑62.
.Inspect the tires for wear.
See Tire Inspection on

Engine Oil Change
When the CHANGE ENGINE OIL
SOON message displays, have the
engine oil and filter changed within
the next 1 000 km/600 mi. If driven
under the best conditions, the
engine oil life system might not
indicate the need for vehicle service
for more than a year. The engine oil
and filter must be changed at least
once a year and the oil life system
must be reset. Your trained dealer
technician can perform this work.
If the engine oil life system is reset
accidentally, service the vehicle
within 5 000 km/3,000 mi since the
last service. Reset the oil life
system when the oil is changed.
See Engine Oil Life System on
page 10‑19.

life percentage. If needed,
change engine oil and filter, and
