Put the new spark plug into the
socket, then screw it into the hole.
Screw it in by hand so you do not
crossthread it.
Remove the spark plug with a 16

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.

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.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
.)
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.
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.

AIR CONDITIONING

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.

Open the hood.
Remove the electrical connector
f rom the bulb by pulling the
connector straight back.
Your car has halogen headlight
bulbs, one on each side. When
replacing a bulb, handle it by its steel
base and protect the glass from
contactwithyourskinorhard
objects. If you touch the glass, clean
it with denatured alcohol and a clean
cloth.
Theheadlightswereproperlyaimed
when your car was new. If you
regularly carry heavy items in the
cargo area, readjustment may be
required. Adjustment of the
headlights should be perf ormed by a
Honda technician or other qualif ied
mechanic.

If you need to park your car f or an
extended period (more than one
month), there are several things you
should do to prepare it f or storage.
Proper preparation helps prevent
deterioration and makes it easier to
get your car back on the road. If
possible, store your car indoors.
If the car is to be stored for a
longer period, it should be
supported on jackstands so the
tires are of f the ground.
Leave one window open slightly (if
the car is being stored indoors).Coverthecarwitha‘‘breathable’’
cover, one made f rom a porous
material such as cotton.
Nonporous materials, such as
plastic sheeting, trap moisture,
which can damage the paint.
Disconnect the battery.
Support the f ront and rear wiper
blade arms with a f olded towel or
ragsotheydonottouchthe
windshield.
To minimize sticking, apply a
silicone spray lubricant to all door
and hatch seals. Also, apply a body
wax to the painted surf aces that
mate with the door and hatch seals. If possible, run the engine f or a
while periodically (pref erably once
amonth).
If you store your car f or 12 months
or longer, have your Honda dealer
perf orm the inspections called f or 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 ). The
replacements called f or in the
maintenance schedule are not
needed unless the car has actually
reached that time or mileage.
Leave the parking brake off. Put

This indicator should light when the
ignition switch is ON (II), and go out
af ter the engine starts. It should
never come on when the engine is
running. If it starts f lashing, it
indicates that the oil pressure
dropped very low f or a moment, then
recovered. If the indicator stays on
with the engine running, it shows
that the engine has lost oil pressure
and serious engine damage is
possible. In either case, you should
take immediate action.Saf ely pull of f the road and shut
of f the engine. Turn on the hazard
warning indicators.
If necessary, add oil to bring the
level back to the full mark on the
dipstick (see page ).
Letthecarsitforaminute.Open
the hood and check the oil level
(see page ). Although oil level
and oil pressure are not directly
connected, an engine that is very
low on oil can lose pressure during
cornering and other driving
maneuvers. Start the engine and watch the oil
pressure indicator. If the light
does not go out within ten seconds,
turn of f the engine. There is a
mechanical problem that needs to
be repaired bef ore you can
continue driving. (See
