GMC ACADIA 2010 Owner's Manual

Vehicle Care 10-25
What to Add
Use only new DOT 3 brake fluid
from a sealed container. See
Recommended Fluids and
Lubricants on page 11‑8.
Always clean the brake fluid
reservoir cap and the area around
the cap before removing it. This
helps keep dirt from entering the
reservoir.
{WARNING
With the wrong kind of fluid in the
brake hydraulic system, the
brakes might not work well. This
could cause a crash. Always use
the proper brake fluid.
Notice:
.Using the wrong fluid can
badly damage brake
hydraulic system parts. For
example, just a few drops of
mineral-based oil, such as
engine oil, in the brake
hydraulic system can damage brake hydraulic
system parts so badly that
they will have to be replaced.
Do not let someone put in
the wrong kind of fluid.
.If brake fluid is spilled on
the vehicle's painted
surfaces, the paint finish can
be damaged. Be careful not
to spill brake fluid on the
vehicle. If you do, wash it off
immediately.
Battery
Refer to the replacement number on
the original battery label when a
new battery is needed.
{DANGER
Battery posts, terminals, and
related accessories contain lead
and lead compounds, chemicals
known to the State of California to
cause cancer and reproductive
harm. Wash hands after handling.
Vehicle Storage
{WARNING
Batteries have acid that can burn
you and gas that can explode.
You can be badly hurt if you are
not careful. See Jump Starting
on
page 10‑78
for tips on working
around a battery without
getting hurt.
Infrequent Usage: Remove the
black, negative (−) cable from the
battery to keep the battery from
running down.
Extended Storage: Remove the
black, negative (−) cable from the
battery or use a battery trickle
charger.

10-26 Vehicle Care
All-Wheel Drive
It is not necessary to check the
all–wheel drive lubricant levels.
A fluid leak is the only reason for
fluid loss. If a leak occurs, take the
vehicle to the dealer/retailer as soon
as possible.
Starter Switch Check
{WARNING
When you are doing this
inspection, the vehicle could
move suddenly. If the vehicle
moves, you or others could be
injured.
1. Before starting this check, be sure there is enough room
around the vehicle.
2. Firmly apply both the parking brake and the regular brake.
See Parking Brake
on
page 9‑27. 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 P (Park) or N (Neutral).
If the vehicle starts in any other
position, contact your dealer/
retailer for service.
Automatic Transmission
Shift Lock Control
System Check
{WARNING
When you are doing this
inspection, the vehicle could
move suddenly. If the vehicle
moves, you or others could be
injured. 1. Before starting this check, be
sure there is enough room
around the vehicle. It should be
parked on a level surface.
2. Firmly apply the parking brake. See Parking Brake
on
page 9‑27.
Be ready to apply the regular
brake immediately if the vehicle
begins to move.
3. With the engine off, turn the ignition to ON/RUN, but do not
start the engine. Without
applying the regular brake, try to
move the shift lever out of
P (Park) with normal effort. If the
shift lever moves out of P (Park),
contact your dealer/retailer for
service.

Vehicle Care 10-27
Ignition Transmission
Lock Check
While parked, and with the parking
brake set, try to turn the ignition to
LOCK/OFF in each shift lever
position.
.The ignition should turn to
LOCK/OFF only when the shift
lever is in P (Park).
.The ignition key should come
out only in LOCK/OFF.
Contact your dealer/retailer if
service is required.
Park Brake and P (Park)
Mechanism Check
{WARNING
When you are doing this check,
the vehicle could begin to move.
You or others could be injured
and property could be damaged.
Make sure there is room in front
of the 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
N (Neutral), slowly remove foot
pressure from the regular brake
pedal. Do this until the vehicle is
held by the parking brake only.
.To check the P (Park)
mechanism's holding ability:
With the engine running, shift to
P (Park). Then release the
parking brake followed by the
regular brake.
Contact your dealer/retailer if
service is required.
Wiper Blade Replacement
Windshield wiper blades should be
inspected for wear or cracking. See
Scheduled Maintenance
on
page 11‑2for more information.

10-28 Vehicle Care
Replacement blades come in
different types and are removed in
different ways. To replace the wiper
blade assembly:
1. Pull the windshield wiper armaway from the windshield.
2. Press the button in the middle ofthe wiper arm connector and pull
the wiper blade away from the
arm connector.
3. Install the new wiper blade and make sure the wiper blade locks
into place. For the proper size and type see
Maintenance Replacement Parts
on
page 11‑10.
Backglass Wiper Blade
To replace the backglass wiper
blade:
1. Pull the wiper blade assembly away from the backglass.
The backglass wiper blade will
not lock in a vertical position so
care should be used when
pulling it away from the vehicle.
2. Rotate the wiper blade assembly, hold the wiper arm in
position, and push the blade
away from the wiper arm.
3. Replace the wiper blade.
4. Return the wiper arm and blade assembly to the rest position on
the glass.
Headlamp Aiming
Headlamp aim has been preset at
the factory and should need no
further adjustment.
However, if your vehicle is damaged
in a crash, the headlamp aim may
be affected. Aim adjustment to the
low-beam headlamps may be
necessary if oncoming drivers flash
their high-beam headlamps at you
(for vertical aim).
If the headlamps need to be
re-aimed, it is recommended that
you take the vehicle to your dealer/
retailer for service.

10-30 Vehicle Care
Electrical System
High Voltage Devices and
Wiring
{WARNING
Exposure to high voltage can
cause shock, burns, and even
death. The high voltage systems
in your vehicle can only be
serviced by technicians with
special training.
High voltage devices are
identified by labels. Do not
remove, open, take apart,
or modify these devices. High
voltage cable or wiring has
orange covering. Do not probe,
tamper with, cut, or modify high
voltage cable or wiring.
Electrical System
Overload
The vehicle has fuses and circuit
breakers to protect against an
electrical system overload.
When the current electrical load is
too heavy, the circuit breaker opens
and closes, protecting the circuit
until the current load returns to
normal or the problem is fixed. This
greatly reduces the chance of circuit
overload and fire caused by
electrical problems.
Fuses and circuit breakers protect
the following in the vehicle:
.Headlamp Wiring
.Windshield Wiper Motor
.Power Windows and other
Power Accessories
Headlamp Wiring
An electrical overload may cause
the lamps to go on and off, or in
some cases to remain off. Have the
headlamp wiring checked right away
if the lamps go on and off or
remain off.
Windshield Wipers
If the wiper motor overheats due to
heavy snow or ice, the windshield
wipers will stop until the motor cools
and will then restart.
Although the circuit is protected
from electrical overload, overload
due to heavy snow or ice, may
cause wiper linkage damage.
Always clear ice and heavy snow
from the windshield before using the
windshield wipers.
If the overload is caused by an
electrical problem and not snow or
ice, be sure to get it fixed.

Vehicle Care 10-31
Fuses and Circuit
Breakers
The wiring circuits in your vehicle
are protected from short circuits by
a combination of fuses, circuit
breakers and fusible thermal links.
This greatly reduces the chance of
fires caused by electrical problems.
Look at the silver-colored band
inside the fuse. If the band is broken
or melted, replace the fuse. Be sure
you replace a bad fuse with a new
one of the identical size and rating.
Fuses of the same amperage can
be temporarily borrowed from
another fuse location, if a fuse goes
out. Replace the fuse as soon as
you can.
Engine Compartment
Fuse Block
The underhood fuse block is located
in the engine compartment, on the
passenger side of the vehicle.
Lift the cover for access to the fuse/
relay block.Notice:
Spilling liquid on any
electrical components on the
vehicle may damage it. Always
keep the covers on any electrical
component.
To remove fuses, hold the end of
the fuse between your thumb and
index finger and pull straight out.
