Tighten the spark plugs caref ully. A
spark plug that is too loose can
overheat and damage the engine.
Overtightening can cause damage to
the threads in the cylinder head.

Check the battery condition by
looking at the test indicator window
on the battery.
The label on the battery explains the
test indicator’s colors.
Check the condition of your car’s
battery monthly. You should check
the color of the test indicator window,
and f or corrosion on the terminals.
To remove the battery cover, pull up
on the right side of the cover to
remove it from the bolt, then pull the
cover out.
To reinstall the cover, insert the pins
ontheleftsideof thecoverintothe
holes and put the cover over the

Check the battery terminals for
corrosion (a white or yellowish
powder). To remove it, cover the
terminals with a solution of baking
soda and water. It will bubble up and
turn brown. When this stops, wash it
of f with plain water. Dry of f the
battery with a cloth or paper towel.
Coat the terminals with grease to
help prevent f uture corrosion.
If the terminals are severely cor-
roded, clean them with baking soda
and water. Then use a wrench to
loosen and remove the cables f rom
the terminals. Always disconnect the
negative ( ) cable f irst and recon-
nect it last. Clean the battery termi-
nals with a terminal cleaning tool or
wire brush. Reconnect and tighten
the cables, then coat the terminals
with grease.If you need to connect the battery to
a charger, disconnect both cables to
prevent damage to the car’s
electrical system.
Battery posts,
terminals and related accessories
contain lead and lead compounds. WARNING:
Wash hands af ter handling.

The battery gives off explosive
hydrogen gas during normal
operation.
A spark or flame can cause the
battery to explode with enough
force to kill or seriously hurt you.
Wear protective clothing and a
face shield, or have a skilled
mechanic do the battery
maintenance.

If your car’s battery is disconnected
or goes dead, all stored driving
positions will be lost. To store the
driving positions again, see the

Charging the battery with the cables
connected can seriously damage your

Check the condition of the wiper
blades at least every six months.
Look f or signs of cracking in the
rubber, or areas that are getting
hard. Replace the blades if you f ind
these signs, or if they leave streaks
and unwiped areas when used.
Disconnect the blade assembly
fromthewiperarmbypushingin
the lock tab. Hold it in while you
push the blade assembly toward
thebaseof thearm.
To replace the blade: Turn the ignition ON (II), switch
the wipers to INT or (low
position), then turn the ignition
OFF when the wiper arm is
approximately midway in its travel. Raise the wiper arm of f the
windshield.

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. 326

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.

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. The dust and pollen f ilter removes
pollen and dust that is brought in
f rom the outside through the climate
control system.
Check the condition of the two drive
belts (power steering belt and
alternator belt). Examine the edges
of each belt f or cracks or f raying.
Check the tension of the power
steering belt by pushing on it with
your thumb midway between the
pulleys.Thebeltshouldhavethefollowing

If you see signs of wear or looseness,

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.
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.
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 affect 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.
The timing belt should normally be
replaced at the intervals shown in
the maintenance schedule.
Replace this belt 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). Inf lation

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.
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).
