Buick Enclave (2009 year). Manual — part 23

Finish Damage

Any stone chips, fractures or deep
scratches in the finish should
be repaired right away. Bare metal
will corrode quickly and may
develop into major repair expense.

Minor chips and scratches can
be repaired with touch-up materials
available from your dealer/retailer.
Larger areas of finish damage
can be corrected in your dealer’s/
retailer’s body and paint shop.

Underbody Maintenance

Chemicals used for ice and snow
removal and dust control can collect
on the underbody. If these are not
removed, corrosion and rust can
develop on the underbody parts such
as fuel lines, frame, floor pan, and
exhaust system even though they
have corrosion protection.

At least every spring, flush these
materials from the underbody
with plain water. Clean any areas
where mud and debris can collect.

Dirt packed in close areas of the
frame should be loosened before
being flushed. Your dealer/retailer or
an underbody car washing system
can do this.

Chemical Paint Spotting

Some weather and atmospheric
conditions can create a chemical
fallout. Airborne pollutants can
fall upon and attack painted surfaces
on the vehicle. This damage can
take two forms: blotchy, ring-shaped
discolorations, and small, irregular
dark spots etched into the paint
surface.

Although no defect in the paint job
causes this, we will repair, at no
charge to the owner, the surfaces of
new vehicles damaged by this
fallout condition within 12 months or
12,000 miles (20 000 km) of
purchase, whichever occurs first.

Vehicle Identification

Vehicle Identification
Number (VIN)

This is the legal identifier for your
vehicle. It appears on a plate in the
front corner of the instrument
panel, on the driver side. It can be
seen through the windshield
from outside the vehicle. The VIN
also appears on the Vehicle
Certification and Service Parts
labels and the certificates of title and
registration.

Service and Appearance Care

Engine Identification

The eighth character in the VIN is
the engine code. This code
helps identify the vehicle’s engine,
specifications, and replacement
parts. See “Engine Specifications”
under Capacities and Specifications
on page 5-98 for your vehicle’s
engine code.

Service Parts
Identification Label

This label is on the inside of the
glove box. It is very helpful if
you ever need to order parts. The
label has the following information:

•

Vehicle Identification
Number (VIN)

•

Model designation

•

Paint information

•

Production options and special
equipment

Do not remove this label from the
vehicle.

Electrical System

High Voltage Devices and
Wiring

{

CAUTION

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.

Add-On Electrical
Equipment

Notice: Do not add anything
electrical to the vehicle unless
you check with your dealer/
retailer first. Some electrical
equipment can damage the
vehicle and the damage would
not be covered by the vehicle’s
warranty. Some add-on electrical
equipment can keep other
components from working as
they should.

Add-on equipment can drain the
vehicle’s battery, even if the vehicle
is not operating.

The vehicle has an airbag system.
Before attempting to add anything
electrical to the vehicle, see
Servicing Your Airbag-Equipped
Vehicle on page 1-56.

Windshield Wiper Fuses

The windshield wiper motor is
protected by a circuit breaker and a
fuse. If the motor overheats due
to heavy snow or ice, the wiper will
stop until the motor cools. If the
overload is caused by some
electrical problem, have it fixed.

Power Windows and
Other Power Options

Circuit breakers in the fuse block
protect the power windows and
other power accessories. When the
current load is too heavy, the
circuit breaker opens and closes,
protecting the circuit until the
problem is fixed or goes away.

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.

Instrument Panel Fuse
Block

The instrument panel fuse block is
located under the instrument
panel on the passenger side of the
vehicle. Pull down on the cover
to access the fuse block.

Maintenance
Schedule

Introduction

Important: Keep engine oil at
the proper level and change as
recommended.

Have you purchased the GM
Protection Plan? The Plan
supplements the vehicle warranties.
See the Warranty and Owner
Assistance booklet or your
dealer/retailer for details.

Maintenance Schedule

6-1

Maintenance
Requirements

Notice: Maintenance intervals,
checks, inspections, replacement
parts, and recommended fluids
and lubricants as prescribed
in this manual are necessary to
keep this vehicle in good working
condition. Any damage caused
by failure to follow scheduled
maintenance might not be
covered by the vehicle warranty.

Your Vehicle and the
Environment

Proper vehicle maintenance not only
helps to keep the vehicle in good
working condition, but also helps the
environment. All recommended
maintenance is important. Improper
vehicle maintenance can even
affect the quality of the air we
breathe. Improper fluid levels or the
wrong tire inflation can increase
the level of emissions from the
vehicle. To help protect the

environment, and to keep the
vehicle in good condition, be sure to
maintain the vehicle properly.

Using the Maintenance
Schedule

We want to help keep this vehicle in
good working condition. But we
do not know exactly how you
will drive it. You might drive very
short distances only a few times a
week. Or you might drive long
distances all the time in very hot,
dusty weather. You might use
the vehicle in making deliveries. Or
you might drive it to work, to do
errands, or in many other ways.

Because of all the different
ways people use their vehicles,
maintenance needs vary. You might
need more frequent checks and
replacements. So please read the
following and note how you
drive. If you have any questions on
how to keep the vehicle in good
condition, see your dealer/retailer.

This schedule is for vehicles that:

•

carry passengers and cargo
within recommended limits on the
Tire and Loading Information
label. See Loading the Vehicle on
page 4-16.

•

are driven on reasonable road
surfaces within legal driving
limits.

•

use the recommended fuel. See
Gasoline Octane on page 5-5.

The services in Scheduled
Maintenance on page 6-3 should be
performed when indicated. See
Additional Required Services
on page 6-6 and Maintenance
Footnotes on page 6-7 for further
information.

Maintenance Schedule

{

CAUTION

Performing maintenance work on
a vehicle can be dangerous. In
trying to do some jobs, you can
be seriously injured. Do your own
maintenance work only if you
have the required know-how and
the proper tools and equipment
for the job. If you have any doubt,
see your dealer/retailer to have a
qualified technician do the work.
See Doing Your Own Service
Work on page 5-4.

Some maintenance services can be
complex. So, unless you are
technically qualified and have the
necessary equipment, have
your dealer/retailer do these jobs.

When you go to your dealer/retailer
for service, trained and supported
service technicians will perform
the work using genuine parts.

To purchase service information,
see Service Publications Ordering
Information on page 7-13.

Owner Checks and Services on
page 6-8 tells what should be
checked, when to check it, and what
can easily be done to help keep
the vehicle in good condition.

The proper replacement parts,
fluids, and lubricants to use
are listed in Recommended Fluids
and Lubricants on page 6-12
and Maintenance Replacement
Parts on page 6-14. When the
vehicle is serviced, make sure these
are used. All parts should be
replaced and all necessary repairs
done before you or anyone else
drives the vehicle. We recommend
the use of genuine parts from
your dealer/retailer.

Scheduled Maintenance

When the CHANGE ENGINE
OIL SOON message displays,
service is required for the vehicle.
Have the vehicle serviced as
soon as possible within the next
600 miles (1 000 km). It is possible
that, if driving under the best
conditions, the engine oil life system
might not indicate that vehicle
service is necessary for over a year.
However, the engine oil and filter
must be changed at least once
a year and at this time the system
must be reset. Your dealer/retailer
has trained service technicians
who will perform this work using
genuine parts and reset the system.

If the engine oil life system is ever
reset accidentally, service the vehicle
within 3,000 miles (5 000 km) since
the last service. Remember to reset
the oil life system whenever the oil is
changed. See Engine Oil Life
System on page 5-13 for information
on the Engine Oil Life System and
resetting the system.
