2010 BUICK LUCERNE air condition

Protecting Exterior Bright Metal Parts
Bright metal parts should be cleaned regularly to keep
their luster. Washing with water is all that is usually
needed. However, chrome polish may be used on
chrome or stainless steel trim, if necessary.
Use special care with aluminum trim. To avoid
damaging protective trim, never use auto or chrome
polish, steam or caustic soap to clean aluminum.
A coating of wax, rubbed to high polish, is
recommended for all bright metal parts.
Windshield and Wiper Blades
Clean the outside of the windshield with glass cleaner.
Clean the rubber blades using a lint free cloth or paper
towel soaked with windshield washer fluid or a mild
detergent. Wash the windshield thoroughly when
cleaning the blades. Bugs, road grime, sap, and a
buildup of vehicle wash/wax treatments may cause
wiper streaking. Replace the wiper blades if they are
worn or damaged.
Wipers can be damaged by:
.Extreme dusty conditions
.Sand and salt
.Heat and sun
.Snow and ice, without proper removal
Aluminum or Chrome-Plated Wheels
and Trim
The vehicle may have either aluminum or
chrome-plated wheels.
Keep the wheels clean using a soft clean cloth with mild
soap and water. Rinse with clean water. After rinsing
thoroughly, dry with a soft clean towel. A wax may then
be applied.
Notice:Chrome wheels and other chrome trim may
be damaged if the vehicle is not washed after
driving on roads that have been sprayed with
magnesium, calcium or sodium chloride. These
chlorides are used on roads for conditions such as
ice and dust. Always wash the vehicle's chrome
with soap and water after exposure.
Notice: Using strong soaps, chemicals, abrasive
polishes, cleaners, brushes, or cleaners that contain
acid on aluminum or chrome-plated wheels, could
damage the surface of the wheel(s). The repairs
would not be covered by the vehicle warranty.
Use only approved cleaners on aluminum or
chrome-plated wheels.

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.
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 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.

Maintenance Schedule
Introduction
Notice:Maintenance intervals, checks, inspections,
recommended fluids, and lubricants are necessary
to keep this vehicle in good working condition.
Damage caused by failure to follow scheduled
maintenance might not be covered by the vehicle
warranty.
As the vehicle owner, you are responsible for the
scheduled maintenance in this section. We recommend
having your dealer/retailer perform these services.
Proper vehicle maintenance helps to keep the vehicle in
good working condition, improves fuel economy, and
reduces vehicle emissions for better air quality.
Because of all the different ways people use vehicles,
maintenance needs vary. The vehicle might need more
frequent checks and services. Please read the
information under Scheduled Maintenance. To keep the
vehicle in good condition, see your dealer/retailer.
The maintenance 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 5‑19.
.are driven on reasonable road surfaces within legal
driving limits.
.use the recommended fuel. See Gasoline Octaneon page 6‑6.
{WARNING:
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 to have a
qualified technician do the work. See Doing Your
Own Service Work on page 6‑4.
At your dealer/retailer, you can be certain that you will
receive the highest level of service available. Your
dealer/retailer has specially trained service technicians,
uses genuine replacement parts, as well as, up to date
tools and equipment to ensure fast and accurate
diagnostics.
The proper replacement parts, fluids, and lubricants to
use are listed in Recommended Fluids and Lubricants
on page 7‑9andMaintenance Replacement Partson
page 7‑11. We recommend the use of genuine parts
from your dealer/retailer.

.Fluids visual leak check (or every 12 months,
whichever occurs first). A leak in any system must
be repaired and the fluid level checked.
.Engine air cleaner filter inspection (vehicles driven
in dusty conditions only). SeeEngine Air Cleaner/
Filter on page 6‑21.
.Brake system inspection (or every 12 months,
whichever occurs first).
Maintenance II
.Perform all services described in Maintenance I.
.Steering and suspension inspection. Visual
inspection for damaged, loose, or missing parts or
signs of wear.
.Engine cooling system inspection. Visual
inspection of hoses, pipes, fittings, and clamps
and replacement, if needed.
.Windshield wiper blade inspection for wear,
cracking, or contamination and windshield and
wiper blade cleaning, if contaminated. See
Windshield and Wiper Blades
on page 6‑106. Worn
or damaged wiper blade replacement. See
Windshield Wiper Blade Replacement
on
page 6‑55.
.Body hinges and latches, key lock cylinders, and
rear compartment, hood, glove box door, and
console door hinges and latches lubrication. See
Recommended Fluids and Lubricants
on
page 7‑9. More frequent lubrication may be
required when vehicle is exposed to a corrosive
environment. Applying silicone grease on
weatherstrips with a clean cloth makes them last
longer, seal better, and not stick or squeak.
.Restraint system component check. See Checking
the Restraint Systems on page 2‑74.
.Engine air cleaner filter inspection. See Engine Air
Cleaner/Filter on page 6‑21.
.Passenger compartment air filter replacement
(or every 12 months, whichever occurs first). More
frequent replacement may be required if vehicle is
driven regularly under dusty conditions.
