Buick Enclave (2009 year). Manual — part 19

Brake Wear

This vehicle has disc brakes. Disc
brake pads have built-in wear
indicators that make a high-pitched
warning sound when the brake
pads are worn and new pads are
needed. The sound can come
and go or be heard all the time the
vehicle is moving, except when
applying the brake pedal firmly.

{

CAUTION

The brake wear warning sound
means that soon the brakes will
not work well. That could lead to
an accident. When the brake wear
warning sound is heard, have the
vehicle serviced.

Notice: Continuing to drive with
worn-out brake pads could
result in costly brake repair.

Some driving conditions or climates
can cause a brake squeal when
the brakes are first applied or lightly
applied. This does not mean
something is wrong with the brakes.

Properly torqued wheel nuts are
necessary to help prevent
brake pulsation. When tires are
rotated, inspect brake pads for wear
and evenly tighten wheel nuts in
the proper sequence to torque
specifications in Capacities and
Specifications on page 5-98.

Brake linings should always be
replaced as complete axle sets.

Brake Pedal Travel

See your dealer/retailer if the brake
pedal does not return to normal
height, or if there is a rapid increase
in pedal travel. This could be a
sign that brake service might
be required.

Brake Adjustment

Every time the brakes are applied,
with or without the vehicle
moving, the brakes adjust for wear.

Replacing Brake System Parts

The braking system on a vehicle
is complex. Its many parts have to
be of top quality and work well
together if the vehicle is to have
really good braking. The vehicle was
designed and tested with top-quality
brake parts. When parts of the
braking system are replaced — for
example, when the brake linings
wear down and new ones are
installed — be sure to get new
approved replacement parts. If this
is not done, the brakes might
not work properly. For example, if
someone puts in brake linings
that are wrong for the vehicle, the
balance between the front and
rear brakes can change — for the
worse. The braking performance
expected can change in many other
ways if the wrong replacement
brake parts are installed.

Battery

This vehicle has a maintenance free
battery. When it is time for a new
battery, see your dealer/retailer
for one that has the replacement
number shown on the original
battery’s label.

For battery replacement, see your
dealer/retailer or the service manual.
To purchase a service manual,
see Service Publications Ordering
Information on page 7-13.
Warning: 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

{

CAUTION

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 5-28 for tips on working
around a battery without
getting hurt.

Infrequent Usage: If the vehicle is
driven infrequently, remove the
black, negative (

−

) cable from the

battery. This helps keep the battery
from running down.

Extended Storage: For extended
storage of the vehicle, remove
the black, negative (

−

) cable from

the battery or use a battery
trickle charger. This helps maintain
the charge of the battery over
an extended period of time.

Jump Starting

If the vehicle’s battery has run
down, you may want to use another
vehicle and some jumper cables
to start your vehicle. Be sure to use
the following steps to do it safely.

{

CAUTION

Batteries can hurt you. They can
be dangerous because:

•

They contain acid that can
burn you.

•

They contain gas that can
explode or ignite.

•

They contain enough
electricity to burn you.

If you do not follow these steps
exactly, some or all of these
things can hurt you.

Notice: Ignoring these steps
could result in costly damage to
your vehicle that would not
be covered by your warranty.

Trying to start your vehicle
by pushing or pulling it will not
work, and it could damage
your vehicle.

1. Check the other vehicle. It must

have a 12-volt battery with a
negative ground system.

Notice: If the other vehicle’s
system is not a 12-volt system
with a negative ground, both
vehicles can be damaged. Only
use vehicles with 12-volt systems
with negative grounds to jump
start your vehicle.

2. Get the vehicles close enough so

the jumper cables can reach, but
be sure the vehicles are not
touching each other. If they are, it
could cause a ground connection
you do not want. You would not
be able to start your vehicle, and
the bad grounding could damage
the electrical systems.

To avoid the possibility of the
vehicles rolling, set the parking
brake firmly on both vehicles
involved in the jump start
procedure. Put an automatic
transmission in P (Park) or a
manual transmission in Neutral
before setting the parking brake.
If you have a four-wheel-drive
vehicle, be sure the transfer case
is not in Neutral.

Notice: If you leave the radio or
other accessories on during
the jump starting procedure, they
could be damaged. The repairs
would not be covered by the
warranty. Always turn off
the radio and other accessories
when jump starting the vehicle.

3. Turn off the ignition on both

vehicles. Unplug unnecessary
accessories plugged into the
cigarette lighter or the accessory
power outlets. Turn off the radio
and all lamps that are not needed.
This will avoid sparks and help
save both batteries. And it could
save the radio!

Service and Appearance Care

4. Open the hoods and locate the

positive (+) and negative (

−

)

terminal locations on the other
vehicle. Your vehicle has a
remote positive (+) and a
remote negative (

−

) jump

starting terminal. See Engine
Compartment Overview on
page 5-10 for more information
on the terminal locations.

{

CAUTION

Using a match near a battery can
cause battery gas to explode.
People have been hurt doing this,
and some have been blinded. Use
a flashlight if you need more light.

Be sure the batteries have
enough water. You do not need to
add water to the ACDelco

®

battery (or batteries) installed in
your new vehicle. But if a battery

(Continued)

CAUTION

(Continued)

has filler caps, be sure the right
amount of fluid is there. If it is
low, add water to take care of that
first. If you do not, explosive gas
could be present.

Battery fluid contains acid that
can burn you. Do not get it on
you. If you accidentally get it in
your eyes or on your skin, flush
the place with water and get
medical help immediately.

{

CAUTION

Fans or other moving engine
parts can injure you badly. Keep
your hands away from moving
parts once the engine is running.

5. Check that the jumper cables do

not have loose or missing
insulation. If they do, you could
get a shock. The vehicles
could be damaged too.

Before you connect the cables,
here are some basic things you
should know. Positive (+) will go
to positive (+) or to a remote
positive (+) terminal if the vehicle
has one. Negative (

−

) will go to a

heavy, unpainted metal engine
part or to a remote negative (

−

)

terminal if the vehicle has one.

Do not connect positive (+) to
negative (

−

) or you will get

a short that would damage the
battery and maybe other
parts too. And do not connect
the negative (

−

) cable to

the negative (

−

) terminal on the

dead battery because this
can cause sparks.

Service and Appearance Care

5-29

6. Connect the red positive (+)

cable to the positive (+) terminal
of the dead battery.

Use a remote positive (+)
terminal if the vehicle has one.

7. Do notlet the other end touch

metal. Connect it to the
positive (+) terminal of the good
battery. Use a remote positive (+)
terminal if the vehicle has one.

8. Now connect the black

negative (

−

) cable to the

negative (

−

) terminal of the

good battery. Use a remote
negative (

−

) terminal if the

vehicle has one.

Do not let the other end touch
anything until the next step. The
other end of the negative (

−

)

cable does not go to the dead
battery. It goes to a heavy,
unpainted metal engine part, or to
a remote negative (

−

) terminal on

the vehicle with the dead battery.

9. Connect the other end of the

negative (

−

) cable at least

18 inches (45 cm) away from the
dead battery, but not near
engine parts that move.

The electrical connection is just
as good there, and the chance
of sparks getting back to the
battery is much less.

Your vehicle has a remote
negative (

−

) terminal for this

purpose.

10. Now start the vehicle with the

good battery and run the
engine for a while.

11. Try to start the vehicle that had

the dead battery. If it will not
start after a few tries, it probably
needs service.

Notice: If the jumper cables are
connected or removed in the
wrong order, electrical shorting
may occur and damage the
vehicle. The repairs would not be
covered by your warranty. Always
connect and remove the jumper
cables in the correct order,
making sure that the cables do not
touch each other or other metal.
