2007 GMC ACADIA brake

Maintenance Footnotes
(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. Check
parking brake adjustment.
(b)Visually inspect front and rear suspension and
steering system for damaged, loose, or missing
parts or signs of wear. Inspect power steering lines
and hoses for proper hook-up, binding, leaks,
cracks, chafing, etc.
(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.(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 434and
Windshield, Backglass, and Wiper Blades on
page 484for more information.
(e)Make sure the safety belt reminder light and all
belts, buckles, latch plates, retractors, and
anchorages 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
look for any opened or broken airbag coverings,
and have them repaired or replaced. The airbag
system does not need regular maintenance.
(f)Lubricate all key lock cylinders, hood latch
assemblies, secondary latches, pivots, spring
anchor and release pawl, hood and door hinges,
rear folding seats, and liftgate hinges. 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.

At Least Once a Year
Starter Switch Check
{CAUTION:
When you are doing this inspection,
the vehicle could move suddenly. If the
vehicle moves, you or others could be
injured.
1. Before you start, be sure you have enough
room around the vehicle.
2. Firmly apply both the parking brake and the
regular brake. SeeParking Brake on page 134.
Do not use the accelerator pedal, and be
ready to turn off the engine immediately if
it starts.
3. Try to start the engine in each gear. The
vehicle should start only in PARK (P) or
NEUTRAL (N). If the vehicle starts in any
other position, contact your dealer/retailer for
service.
Automatic Transmission Shift Lock
Control System Check
{CAUTION:
When you are doing this inspection,
the vehicle could move suddenly. If the
vehicle moves, you or others could be
injured.
1. Before you start, be sure you have enough
room around the vehicle. It should be parked
on a level surface.
2. Firmly apply the parking brake. SeeParking
Brake on page 134.
Be ready to apply the regular brake
immediately if the vehicle begins to move.
3. With the engine off, turn the ignition to ON,
but do not start the engine. Without applying
the regular brake, try to move the shift lever
out of PARK (P) with normal effort. If the shift
lever moves out of PARK (P), contact your
dealer/retailer for service.
509

Ignition Transmission Lock Check
While parked, and with the parking brake set,
try to turn the ignition to OFF in each shift lever
position.
The ignition should turn to OFF only when the
shift lever is in PARK (P).
The ignition key should come out only in OFF.
Contact your dealer/retailer if service is required.
Parking Brake and Automatic
Transmission Park (P) Mechanism Check
{CAUTION:
When you are doing this check, your
vehicle could begin to move. You or
others could be injured and property
could be damaged. Make sure there is
room in front of your vehicle in case it
begins to roll. Be ready to apply the
regular brake at once should the vehicle
begin to move.Park on a fairly steep hill, with the vehicle facing
downhill. Keeping your foot on the regular
brake, set the parking brake.
To check the parking brake’s holding ability:
With the engine running and the transmission in
NEUTRAL (N), slowly remove foot pressure
from the regular brake pedal. Do this until the
vehicle is held by the parking brake only.
To check the PARK (P) mechanism’s holding
ability: With the engine running, shift to
PARK (P). Then release the parking brake
followed by the regular brake.
Contact your dealer/retailer if service is required.
Underbody Flushing Service
At least every spring, use plain water to ush
any corrosive materials from the underbody.
Take care to clean thoroughly any areas where
mud and other debris can collect.

Event Data Recorders
Some information about your vehicle’s
performance and how it is driven may be recorded
on various modules if a crash occurs. Some
people refer to these modules asevent data
recorders (EDRs). These modules may record
several seconds of pre-crash and crash data, such
as data related toengine speed, brake
application, throttle position, vehicle speed,
yaw rate, steering wheel angle, lateral
acceleration, safety belt usage, airbag
readiness, airbag performanceandthe severity
of the collision.Unlike the ight data recorders
on airplanes, these modules do not record sounds
or conversations.To retrieve this data, special equipment and
access to the vehicle or the module that stores
the data are required. Certain data may also
be sent to or retrieved by OnStar®(see below).
GM will not access this information or share it with
others except: with the consent of the vehicle
owner or, if the vehicle is leased, with the consent
of the lessee; in response to an official request
of police or similar government office; as part
of GM’s defense of litigation through the discovery
process; or, as required by law. Data that GM
collects or receives may also be used for
GM research needs or may be made available to
others for research purposes, where a need is
shown and the data is not tied to a specic vehicle
or vehicle owner.
Others may be able to retrieve this data if they
have access to the vehicle and have the special
equipment necessary to download the data.
