Vehicle Care 445
Caution
To avoid surface damage on
wheels and wheel trim, do
not use strong soaps,
chemicals, abrasive polishes,
cleaners, or brushes. Use
only GM approved cleaners.
Do not drive the vehicle
through an automatic car
wash that uses silicon
carbide tire/wheel cleaning
brushes. Damage could
occur and the repairs would
not be covered by the
vehicle warranty.
Brake System
Visually inspect brake lines
and hoses for proper hook-up,
binding, leaks, cracks, chafing,
etc. Inspect disc brake pads
for wear and rotors for
surface condition. Inspect all
other brake parts.
Steering, Suspension, and
Chassis Components
Visually inspect steering,
suspension, and chassis
components for damaged,
loose, or missing parts or signs
of wear at least once a year.
Inspect power steering for
proper electrical connections,
binding, cracks, chafing, etc.
Visually check constant
velocity joint boots and axle
seals for leaks.
Body Component
Lubrication
Lubricate all key lock cylinders,
door hinges, hood hinges,
liftgate hinges, and the steel
fuel door hinges, unless the
components are plastic.
Applying silicone grease on
weatherstrips with a clean
cloth will make them last
longer, seal better, and not
stick or squeak.
Underbody Maintenance
At least twice a year, spring
and fall, use plain water to
flush any corrosive materials
from the underbody. Take care
to thoroughly clean any areas
where mud and other debris
can collect.
Do not directly power wash
the transfer case and/or
front/rear axle output seals.
High pressure water can
overcome the seals and
contaminate the fluid.
Contaminated fluid will
decrease the life of the
transfer case and/or axles and
should be replaced.
Sheet Metal Damage
If the vehicle is damaged and
requires sheet metal repair or
replacement, make sure the
body repair shop applies
anti-corrosion material to
parts repaired or replaced to
restore corrosion protection.

Maintenance
Schedule
Tire Rotation and
Required Services Every
12 000 km (7,500 mi)
Tires are rotated to achieve a
more uniform wear for all tires.
The first rotation is the most
important.
Anytime unusual wear is
noticed, rotate the tires as
soon as possible, check for
proper tire inflation pressure,
and check for damaged tires
or wheels. If the unusual wear
continues after the rotation,
check the wheel alignment.
See When It Is Time for New
Tires0418 and Wheel
Replacement 0423.
.Perform Multi-Point Vehicle
Inspection. See Multi-Point
Vehicle Inspection (MPVI)
0456.
.Lubricate body components.

Service
Every 12 000 km (7,500 mi)
.Check engine oil level and oil
life percentage. If needed,
change engine oil and filter,
and reset oil life system. Or
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

the engine oil life system
may not indicate the need
for vehicle service for up to
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
0373.
.When the REPLACE AT
NEXT OIL CHANGE
message displays, the engine
air filter should be replaced
at the next engine oil
change. When the REPLACE
ENGINE AIR FILTER SOON
message displays, the engine
air filter should be replaced
at the earliest convenience.
Reset the engine air filter life
system after the engine air
filter is replaced. See Engine
Air Filter Life System 0374.
Every 36 000 km (22,500 mi)
.Passenger compartment air
filter replacement (or every
24 months, whichever
occurs first). More frequent
replacement may be needed
if the vehicle is driven in
areas with heavy traffic,
poor air quality, areas with
high dust levels or are
sensitive to environmental
allergens. Filter replacement
