Ai
r Conditionin g Syste m

Your car's air conditioning is a sealed system. Any major maintenance,
such as recharging, should be done
by a qualified mechanic. You can do a couple of things to make sure the
air conditioning works efficiently.
Periodically check the engine's
radiator and air conditioning
condenser for leaves, insects, and dirt stuck to the front surface. These
block the air flow and reduce cooling efficiency. Use a light spray from a
hose or a soft brush to remove them.

The condenser and radiator fins bend
easily. Only use a low-pressure spray
or soft-bristle brush to clean them.
Run the air conditioning at least once
a week during the cold weather
months. Run it for at least ten
minutes while you are driving at a
steady speed with the engine at
normal operating temperature. This
circulates the lubricating oil con-
tained in the refrigerant.
If the air conditioning does not get as

cold as before, have your dealer

check the system. Recharge the
system with Refrigerant HFC-134a
(R-134a). (See Specifications on page 298.)

Whenever you have the air conditioning

system serviced, make sure the service

facility uses a refrigerant recycling
system. This system captures the
refrigerant for reuse. Releasing
refrigerant into the atmosphere can

damage the environment.

Timin g Bel t
The timing belt and balancer belt should normally be replaced at the
intervals shown in the maintenance

schedule.

Replace these belts at 60,000 miles (U.S.) or 100,000 km (Canada) if you
regularly drive your car in one or
more of these conditions:
In very high temperatures
(over 110°F,43°C).
In very low temperatures

(under —20°F, — 29°C). Tire
s
To safely operate your car, your tires must be the proper type and size, in
good condition with adequate tread, and correctly inflated. The following
pages give more detailed information on how and when to check air
pressure, how to inspect your tires
for damage and wear, and what to do
when your tires need to be replaced.
Inflatio
n

Keeping the tires properly inflated
provides the best combination of
handling, tread life and riding comfort. Underinflated tires wear
unevenly, adversely affect handling and fuel economy, and are more
likely to fail from being overheated. Overinflated tires can make your car
ride more harshly, are more prone to damage from road hazards, and wear

unevenly.

We recommend that you visually check your tires every day. If you
think a tire might be low, check it immediately with a tire gauge.

Maintenanc e

Using tires that are excessively
worn or improperly inflated can
cause a crash in which you can be seriously hurt or killed.
Follow all instructions in this
owner's manual regarding tire inflation and maintenance.

Tire
s
Tubeless tires have some ability to self-seal if they are punctured.
However, because leakage is often
very slow, you should look closely
for punctures if a tire starts losing
pressure. Inspectio
n
Every time you check inflation, you
should also examine the tires for
damage, foreign objects, and wear.
You should look for: Bumps or bulges in the tread or
side of the tire. Replace the tire if
you find either of these conditions. Cuts, splits, or cracks in the side
of the tire. Replace the tire if you
can see fabric or cord. Excessive tread wear.
Your car's tires have wear indicators
molded into the tread. When thetread wears down to that point, you
will see a 1/2 inch (12.7 mm) wide
band running across the tread. This shows there is less than 1
/16 inch
(1.6 mm) of tread left on the tire. A
tire that is this worn gives very little
traction on wet roads. You should
replace the tire if you can see the
tread wear indicator in three or more
places around the tire.

Snow Tires
If you mount snow tires on your
Acura, make sure they are radial tires of the same size and load rangeas the original tires. Mount snow
tires on all four wheels to balance
your car's handling in all weather conditions. Keep in mind the traction
provided by snow tires on dry roads
may not be as high as your car's original equipment tires. You should
drive cautiously even when the roads
are clear. Check with the tire dealer
for maximum speed recommen-
dations.
Tire Chains
Because your Acura has limited tire
clearance, mount only SAE Class "S"
cable-type traction devices on the
front tires. Use traction devices only when required by driving conditionsor local laws. Make sure they are the
correct size for your tires.
Metal link-type "chains" should not
be used. No matter how tight they seem to be installed, they can come
into contact with the body and
suspension, causing serious damage. When installing cables, follow the
manufacturer's instructions and
mount them as tightly as you can.
Drive slowly with them installed. If
you hear them coming in contact with the body or chassis, stop andinvestigate. Make sure the cables are
installed tightly, and that they are
not contacting the brake lines or
suspension.

Remove them as soon as you begin driving on cleared roads.

Traction devices that are the wrong
size or improperly installed can damage your car's brake lines,
suspension, body, and wheels. Stop
driving if they are hitting any part of the car.

Storin
g You r Ca r

If you need to park your car for an
extended period (more than one
month), there are several things you
should do to prepare it for storage.
Proper preparation helps prevent
deterioration and makes it easier to
get your car back on the road. If
possible, store your car indoors. Fill the fuel tank.
Change the engine oil and filter
(see page 217). Wash and dry the exterior
completely.
Clean the interior. Make sure the
carpeting, floor mats, etc. are
completely dry. Leave the parking brake off. Put
the transmission in Park. Block the rear wheels.
If the car is to be stored for a
longer period, it should be supported on jackstands so the
tires are off the ground. Leave one window open slightly (if
the car is being stored indoors). Disconnect the battery.
Support the front wiper blade
arms with a folded towel or rag so
they do not touch the windshield.
To minimize sticking, apply a silicone spray lubricant to all door
and trunk seals. Also, apply a
vehicle body wax to the painted surfaces that mate with the door
and trunk seals. Cover the car with a "breathable"
cover, one made from a porous
material such as cotton.
Nonporous materials, such as
plastic sheeting, trap moisture,
which can damage the paint. If possible, run the engine for a
while periodically (preferably once a month).
If you store your car for 12 months or longer, have your Acura dealer
perform the inspections called for in
the 24 months/30,000 miles (48,000
km) maintenance schedule (Normal Conditions) as soon as you take it
out of storage (see page 206). The
replacements called for in the
maintenance schedule are not
needed unless the car has actually
reached that time or mileage.

Maintenance

Corrosion
Protectio n

Two factors normally contribute to causing corrosion in your car:
1. Moisture trapped in body cavities. Dirt and road salt that collects in
hollows on the underside of the
vehicle stays damp, promoting corrosion in that area.
2. Removal of paint and protective coatings from the exterior and
underside of the car. Many corrosion-preventive measures
are built into your Acura. You can
help keep your car from corroding
by performing some simple periodic

maintenance:
Repair chips and scratches in the
paint as soon as you discover them. Inspect and clean out the drain
holes in the bottom of the doors
and body. Check the floor coverings for
dampness. Carpeting and floor
mats may remain damp for a long
time, especially in winter. This dampness can eventually cause
the floor panels to corrode. Use a high-pressure spray to clean
the underside of your car. This is especially important in areas that
use road salt in winter. It is also a
good idea in humid climates and areas subject to salt air. Be carefulof the ABS wheel sensors and
wiring at each wheel. Have the corrosion-preventive
coatings on the underside of your
car inspected and repaired
periodically.

Appearanc e Car e

Emission
s Control s

The burning of gasoline in your car's engine produces several byproducts.
Some of these are carbon monoxide (CO), oxides of nitrogen (NOx) and
hydrocarbons (HC). Gasoline evaporating from the tank also
produces hydrocarbons. Controlling
the production of NOx, CO, and HC
is important to the environment.
Under certain conditions of sunlight
and climate, NOx and HC react to
form photochemical "smog." Carbon
monoxide does not contribute to smog creation, but it is a poisonous

gas.
Th
e Clea n Ai r Ac t

The United States Clean Air Act*
sets standards for automobile

emissions. It also requires that

automobile manufacturers explain to owners how their emissions controls

work and what to do to maintain
them. This section summarizes how

the emissions controls work.

Scheduled maintenance is on page
206.

* In Canada, Acura vehicles comply

with the Canadian Motor Vehicle
Safety Standards (CMVSS) for

Emissions valid at the time they are

manufactured.

Crankcas e Emission s Contro l
Syste m
Your car has a Positive Crankcase
Ventilation System. This keeps gasses that build up in the engine'scrankcase from going into the
atmosphere. The Positive Crankcase
Ventilation valve routes them from the crankcase back to the intake
manifold. They are then drawn into
the engine and burned.
Evaporativ e Emission s Contro l
Syste m
As gasoline evaporates in the fuel tank, an evaporative emissionscontrol canister filled with charcoal
adsorbs the vapor. It is stored in this
canister while the engine is off. After
the engine is started and warmed up,
the vapor is drawn into the engine and burned during driving.
Onboar d Refuelin g Vapo r
Recover y
The Onboard Refueling Vapor Recovery (ORVR) system captures
the fuel vapors during refueling. The
vapors are adsorbed in a canister
filled with activated carbon. While driving, the fuel vapors are drawn
into the engine and burned off.
