Maintenance Footnotes
#
Lubricate the front suspension,
steering linkage, and parking brake
cable guides. Control arm ball
joints require lubrication but should
not be lubricated unless their
temperature is 10°F (-12°C) or
higher, or they could be damaged.
(a) 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 other brake parts, including
calipers, parking brake, etc. (b)
Visually inspect front and rear
suspension and steering system
for damaged, loose, or missing
parts, signs of wear or lack
of lubrication. Inspect power steering
lines and hoses for proper hook-up,
binding, leaks, cracks, chafing,
etc. Visually check constant velocity
joints, rubber boots and axle
seals for leaks. Rotate and inspect
U-joints, retainers, and bolts on
rear drive shaft for seizing or
loosening. (c)
Visually inspect hoses and have
them replaced if they are cracked,
swollen, or deteriorated. Inspect
all pipes, fittings, and clamps;
replace with genuine parts as
needed. To help ensure proper
operation, a pressure test of
the cooling system and pressure
cap and cleaning the outside of
the radiator and air conditioning
condenser is recommended at least
once a year.
Maintenance Schedule 6-7

(d)Inspect wiper blades for wear,
cracking, or contamination.
Clean the windshield and wiper
blades, if contaminated. Replace
wiper blades that are worn or
damaged. See Windshield Wiper
Blade Replacement on page 5-44
and Windshield, Backglass,
and Wiper Blades on page 5-87
for more information.
(e)Make sure the safety belt
reminder light and safety belt
assemblies are working properly.
Look for any other loose or
damaged safety belt system parts.
If you see anything that might
keep a safety belt system from doing
its job, have it repaired. Have any
torn or frayed safety belts replaced.
Also see Checking the Restraint
Systems on page 1-60.
(f)Lubricate all key lock cylinders,
hood latch assembly, secondary
latch, pivots, spring anchor, release
pawl, rear compartment hinges,
outer endgate handle pivot points,
rear door detent link, rollermechanism, endgate handle pivot
points, latch bolt, fuel door hinge,
locks, and folding seat hardware.
More frequent lubrication may
be required when exposed to a
corrosive environment. Applying
silicone grease on weatherstrips
with a clean cloth will make
them last longer, seal better, and
not stick or squeak.
(g)Check vent hose at transfer
case for kinks and proper
installation.
(h)Change automatic transmission
fluid and filter if the vehicle is
mainly driven under one or more of
these conditions:
In heavy city traffic where the
outside temperature regularly
reaches 90°F (32°C) or higher.
In hilly or mountainous terrain.
When doing frequent trailer
towing.
Uses such as found in taxi,
police, or delivery service.(i)Drain, flush, and refill cooling
system. This service can be
complex; you should have your
dealer/retailer perform this service.
See Engine Coolant on page 5-23
for what to use. Inspect hoses.
Clean radiator, condenser,
pressure cap, and filler neck.
Pressure test the cooling system
and pressure cap.
(j)A fluid loss in any vehicle system
could indicate a problem. Have the
system inspected and repaired
and the fluid level checked. Add fluid
if needed.
(k)Visually inspect belt for fraying,
excessive cracks, or obvious
damage. Replace belt if necessary.

Note to Canadian Customers: All

funds. Canadian residents are to

Recording and
Privacy
Your GM vehicle has a number of
sophisticated computers that record
information about the vehicle’s
performance and how it is driven. For
example, your vehicle uses computer
modules to monitor and control
engine and transmission
performance, to monitor the
conditions for airbag deployment and
deploy airbags in a crash and, if so
equipped, to provide antilock braking
to help the driver control the vehicle.
These modules may store data to
help your dealer/retailer technician
service your vehicle. Some modules
may also store data about how you
operate the vehicle, such as rate of
fuel consumption or average speed.
These modules may also retain the
owner’s personal preferences, such
as radio pre-sets, seat positions, and
temperature settings.
Event Data Recorders
This vehicle has an Event
Data Recorder (EDR). The main
purpose of an EDR is to record, in
certain crash or near crash-like
situations, such as an airbag
deployment or hitting a road
obstacle, data that will assist in
understanding how a vehicle’s
systems performed. The EDR is
designed to record data related to
vehicle dynamics and safety
systems for a short period of time,
typically 30 seconds or less.
The EDR in this vehicle is designed
to record such data as:
How various systems in your
vehicle were operating
Whether or not the driver and
passenger safety belts were
buckled/fastened
How far, if at all, the driver was
pressing the accelerator and/or
brake pedal
How fast the vehicle was
traveling
