Vehicle Care 273
vehicle is significantly pulling to one
side or the other. Some slight pull to
the left or right, depending on the
crown of the road and/or other road
surface variations such as troughs
or ruts, is normal. If the vehicle is
vibrating when driving on a smooth
road, the tires and wheels may need
to be rebalanced. See your dealer
for proper diagnosis.
Wheel Replacement
Replace any wheel that is bent,
cracked, or badly rusted or
corroded. If wheel nuts keep coming
loose, the wheel, wheel bolts, and
wheel nuts should be replaced.
If the wheel leaks air, replace it.
Some aluminum wheels can be
repaired. See your dealer if any of
these conditions exist.
Your dealer will know the kind of
wheel that is needed.
Each new wheel should have the
same load-carrying capacity,
diameter, width, offset, and be
mounted the same way as the one it
replaces.Replace wheels, wheel bolts, wheel
nuts, or Tire Pressure Monitor
System (TPMS) sensors with new
GM original equipment parts.
{Warning
Using the wrong replacement
wheels, wheel bolts, or wheel
nuts can be dangerous. It could
affect the braking and handling of
the vehicle. Tires can lose air,
and cause loss of control, causing
a crash. Always use the correct
wheel, wheel bolts, and wheel
nuts for replacement.
Caution
The wrong wheel can also cause
problems with bearing life, brake
cooling, speedometer or
odometer calibration, headlamp
aim, bumper height, vehicle
ground clearance, and tire or tire
chain clearance to the body and
chassis.
Used Replacement Wheels
{Warning
Replacing a wheel with a used
one is dangerous. How it has
been used or how far it has been
driven may be unknown. It could
fail suddenly and cause a crash.
When replacing wheels, use a
new GM original equipment
wheel.
Tire Chains
{Warning
Do not use tire chains. There is
not enough clearance. Tire chains
used on a vehicle without the
proper amount of clearance can
cause damage to the brakes,
suspension, or other vehicle
parts. The area damaged by the
tire chains could cause loss of
control and a crash.

Service and Maintenance 297
At your dealer, you can be certain
that you will receive the highest
level of service available. Your
dealer has specially trained service
technicians, uses genuine
replacement parts, as well as,
up-to-date tools and equipment to
ensure fast and accurate
diagnostics.
The proper replacement parts,
fluids, and lubricants to use are
listed inRecommended Fluids and
Lubricants 0301 andMaintenance
Replacement Parts 0302. We
recommend the use of genuine
parts from your dealer.
Rotation of New Tires
Tire rotation is not recommended if
the vehicle has different size tires
on the front and rear wheels. If tire
rotation is recommended for the
vehicle, to maintain ride, handling,
and performance of the vehicle, it is
important that the first rotation
service for new tires be performed.
Tires should be rotated every
service. See Tire Rotation 0269.Maintenance
Schedule
When the Change Engine Oil
Soon Message Displays
Change engine oil and filter. See
Engine Oil 0234. An Emission
Control Service.
When the CHANGE ENGINE OIL
SOON message displays, service is
required for the vehicle as soon as
possible, within the next 1 000 km/

technicians who will perform this
work and reset the system. If the
engine oil life system is reset
accidentally, service the vehicle
within 5 000 km/3,000 miles since
the last service. Reset the oil life
system whenever the oil is changed.
