Maintenance Schedule for Severe Conditions (listed by distance/time)

Run the air conditioning at least once
a week during the cold weather
months. Run it f or 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 ref rigerant.If the air conditioning does not get as
cold as before, have your dealer
check the system. Recharge the
system with Ref rigerant HFC-134a
(R-134a). (See Specif ications on page
.)
Periodically check the engine’s
radiator and air conditioning
condenser f or leaves, insects, and
dirt stuck to the f ront surf ace. These
block the air f low and reduce cooling
ef f iciency. Use a light spray f rom a
hose or a sof t brush to remove them. Your car’s air conditioning is a sealed
system. Any major maintenance,
such as recharging, should be done
by a qualif ied mechanic. You can do
a couple of things to make sure the
air conditioning works ef f iciently. 312

Whenever you have the air conditioning
system serviced, make sure the service
f acility uses a ref rigerant recycling
system. This system captures the
ref rigerant f or reuse. Releasing
ref rigerant into the atmosphere can
damage the environment.
The condenser and radiator f ins bend
easily. Only use a low-pressure spray
or sof t-bristle brush to clean them.

The belts should have the f ollowing
‘‘play’’ or def lection.
Alternator belt:
Check the condition of the three
drive belts. Examine the edges of
each belt f or cracks or f raying.
This f ilter should be replaced every
30,000 miles (48,000 km) under nor-
mal conditions. It should be replaced
every 15,000 miles (24,000 km) if you
drive primarily in urban areas that
have high concentrations of soot in
the air f rom industry and diesel-pow-
ered vehicles. Replace it more of ten
if air f low f rom the climate control
system becomes less than usual.
Have dust and pollen f ilter replaced
by your Acura dealer.
Check the tension of each belt by
pushingonitwithyourthumb
midway between the pulleys.If you see signs of wear or looseness,
have your dealer adjust or replace
the belts. Power steering belt: Compressor belt:

µµWe recommend that you visually
check your tires every day. If you
think a tire might be low, check it
immediately with a tire gauge.
The timing belt and balancer belt
should normally be replaced at the
intervals shown in the maintenance
schedule.
In very high temperatures
(over 110°F, 43°C).
In very low temperatures
(under 20°F, 29°C). To saf ely operate your car, your tires
must be the proper type and size, in
good condition with adequate tread,
and correctly inf lated. The f ollowing
pages give more detailed inf ormation
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.
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: Keeping the tires properly inf lated
provides the best combination of
handling, tread lif e, and riding
comf ort. Underinf lated tires wear
unevenly, adversely af f ect handling
and f uel economy, and are more
likely to f ail f rom being overheated.
Overinf lated tires can make your car
ride more harshly, are more prone to
damage f rom road hazards, and wear
unevenly.

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.

Use a gauge to measure the air
pressure at least once a month. Even
tires that are in good condition may
lose one to two psi (10 to 20 kPa, 0.1
to 0.2 kgf /cm ) per month.
Remember to check the spare tire at
thesametimeyoucheckallthe
other tires.The following chart shows the
recommended cold tire pressures f or
most normal driving conditions and
speeds. Tire pressures f or high
speed driving are the same as f or
normal driving.
These pressures are also given on
thetireinformationlabelonthe
driver’s doorjamb. Thecompactsparetirepressureis:
If you check the pressure when the
tires are hot (the car has been driven
several miles), you will see readings
4 to 6 psi (30 to 40 kPa, 0.3 to 0.4
kgf /cm ) higher than the cold
reading. This is normal. Do not let
air out to match the specified cold
pressure. The tire will be
underinf lated.
Youshouldgetyourowntire
pressure gauge and use it whenever
you check your tire pressures. This
will make it easier f or you to tell if a
pressure loss is due to a tire problem
and not due to a variation between
gauges.
Check the pressure in the tires when
they are cold. This means the car
has been parked f or at least three
hours. If you have to drive the car
bef ore checking the tire pressure,
the tires can still be considered
‘‘cold’’ if you drive less than 1 mile
(1.6 km).

If you must drive the car a short
distance in this condition, drive
slowly and cautiously.
If it comes on at any other time, it
indicates a problem with the car’s
brake system. In most cases, the
problem is a low f luid level in the
brake f luid reservoir. Press lightly on
the brake pedal to see if it f eels
normal. If it does, check the brake
f luid level the next time you stop at a
service station (see page ). If the
fluid level is low, take the car to your
dealer and have the brake system
inspected f or leaks or worn brake
pads. Slow down by shif ting to a lower
gear, and pull to the side of the road
when it is saf e. Because of the
longer distance needed to stop, it is
hazardous to drive the car. You
should have it towed, and repaired as
soon as possible. (See
on page .)
However, if the brake pedal does not
f eel normal, you should take
immediate action. Because of the
brake system’s dual-circuit design, a
problem in one part of the system
will still give you braking at two
wheels. You will f eel the brake pedal
go down much f arther bef ore the car
begins to slow down, and you will
have to press harder on the pedal.
The distance needed to stop will be
much longer. If the ABS indicator and the VSA
system indicator come on with this
indicator, have the car inspected by
your dealer immediately.
The Brake System Indicator
normallycomesonwhenyouturn
the ignition switch ON (II). It is a
reminder to check the parking brake.
It comes on and stays lit if you do not
f ully release the parking brake. 240

ÎThe United States Clean Air Act
sets standards f or automobile
emissions. It also requires that
automobile manufacturers explain to
owners how their emissions controls
workandwhattodotomaintain
them. This section summarizes how
the emissions controls work.
Scheduled maintenance is on page .
In Canada, Acura vehicles comply
with the Canadian Motor Vehicle
Saf ety Standards (CMVSS) f or
Emissions valid at the time they are
manuf actured.
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
f orm photochemical ‘‘smog.’’ Carbon
monoxide does not contribute to
smog creation, but it is a poisonous
gas.
Your car has a Positive Crankcase
Ventilation System. This keeps
gasses that build up in the engine’s
crankcase from going into the
atmosphere. The Positive Crankcase
Ventilation valve routes them fromthe crankcase back to the intake
manif old. They are then drawn into
the engine and burned.
As gasoline evaporates in the f uel
tank, an evaporative emissions
control canister f illed with charcoal
adsorbs the vapor. It is stored in this
canister while the engine is of f . Af ter
the engine is started and warmed up,
the vapor is drawn into the engine
and burned during driving.
The Onboard Ref ueling Vapor
Recovery (ORVR) system captures
the f uel vapors during ref ueling. The
vapors are adsorbed in a canister
f illed with activated carbon. While
driving, the f uel vapors are drawn
into the engine and burned of f .
