Air Cleaner Element
The air cleaner element should be cleaned or replaced according to the
time and distance recommendations
in the maintenance schedule. Cleaning (Severe Conditions)
Clean the air cleaner element by
blowing compressed air through it in
the opposite direction to normal air
flow. If you do not have access to compressed air (such as a service
station), ask your Honda dealer to do
this service.
Follow the replacement procedure
for removal and reinstallation. Replacement
The air cleaner element is inside the air cleaner housing on the passenger's
side of the engine compartment.
To replace it:
1. Remove the two pins holding the air intake cover by pulling the
head on each pin. Remove the air
intake cover.
2. Remove the air duct from the air cleaner housing cover.

Spark Plugs

5. Torque the spark plug. (If you do not have a torque wrench, tighten
the spark plug two-thirds of a turn
after it contacts the cylinder head.)
Tightening torque:13 lbf.ft (18 N.m, 1.8 kgf.m)

Tighten the spark plugs
carefully. A
spark plug that is too loose can overheat and damage the engine. Overtightening can cause damage to
the threads in the cylinder head.
6. Install the spark plug cap.
7. Repeat this procedure for the other three spark plugs.

Air Conditioning System

Your vehicle's air conditioning is a sealed system. Any major mainte-
nance, 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.
AIR CONDITIONING

CONDENSER

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 asteady 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 248.
)

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.

Storing Your Vehicle

If you need to park your vehicle 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 vehicle back on the road. If
possible, store your vehicle indoors.
Fill the fuel tank.
Change the engine oil and filter(see page 175 ). 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 vehicle 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 vehicle is being stored

indoors).

Disconnect the battery.
Support the front and rear 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 body
wax to the painted surfaces that mate with the door and trunk seals. Cover the vehicle with a
"breathable" vehicle 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 vehicle for 12
months or longer, have your Honda 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 164 ).
The replacements called for in the maintenance schedule are not
needed unless the vehicle has
actually reached that time or mileage.

If Your Engine Won't Start

Diagnosing why your engine won't start falls into two areas, depending
on what you hear when you turn the
key to START (III):
You hear nothing, or almostnothing. The engine's starter
motor does not operate at all, or
operates very slowly.
You can hear the starter motor operating normally, or the starter
motor sounds like it is spinning
faster than normal, but the engine does not start up and run.
Nothing Happens or the Starter
Motor Operates Very Slowly
When you turn the ignition switch to START (III), you do not hear the
normal noise of the engine trying tostart. You may hear a clicking sound
or series of clicks, or nothing at all.
Check these things: Your vehicle has the Immobilizer
System. You should use a
properly-coded master or valet key
to start the engine (see page 67).
A key that is not properly coded will cause the immobilizer systemindicator in the dash panel to blink
rapidly.
Check the transmission interlock.
The transmission must be in Park or Neutral or the starter will not
operate.

Turn the ignition switch to ON (II).
Turn on the headlights and check their brightness. If the headlightsare very dim or don't light at all,
the battery is discharged. See

Jump Starting on page 230.
Turn the ignition switch to START
(III). If the headlights do not dim,
check the condition of the fuses. If
the fuses are OK, there is proba-
bly something wrong with the electrical circuit for the ignitionswitch or starter motor. You will
need a qualified technician to determine the problem. (See
Towing on page 244.)
If the headlights dim noticeably or
go out when you try to start theengine, either the battery is dis-
charged or the connections are
corroded. Check the condition of
the battery and terminal connec-
tions (see page 189). You can
then try jump starting the vehicle
from a booster battery (see page
231).

If Your Engine Won't Start, Jump Starting
The Starter
Operates Normally
In this case, the starter motor's
speed sounds normal, or even faster
than normal, when you turn the
ignition switch to START (III), but
the engine does not run. Are you using the proper startingprocedure? Refer to Starting the
Engine on page 141.
Do you have fuel? Turn the
ignition switch to ON (II) for a
minute and watch the fuel gauge.
The low fuel level warning light may not be working, so you were
not reminded to fill the tank.
There may be an electrical problem, such as no power to the
fuel pump. Check all the fuses (see page 242).
If you find nothing wrong, you will
need a qualified technician to find
the problem. See Towing on page

244.
Jump Starting
If your vehicle's battery has rundown, you may be able to start the
engine by using a booster battery.
Although this seems like a simple procedure, you should take several

precautions.

You cannot start a Honda by pushing or pulling it. To jump start your vehicle, follow
these directions closely:
1. Open the hood and check the physical condition of the battery(see page 189 ). In very cold
weather, check the condition of the electrolyte. If it seems slushyor like ice, do not try jump starting
until it thaws.

If a battery sits in extreme cold, the electrolyte inside can freeze.
Attempting to jump start with a frozen battery can cause it to rupture.

2. Turn off all the electrical acces- sories: heater, A/C, stereo system,
lights, etc.
Put the transmission in Neutral or
Park and set the parking brake.

Taking Care of the Unexpected
A battery can explode if you do
not follow the correct procedure,
seriously injuring anyone nearby.
Keep all sparks, open flames,
and smoking materials away
from the battery.

Jump Starting

3. Connect one jumper cable to the positive ( + ) terminal on the
booster battery. Connect the other end to the positive ( + ) terminal
on your Honda's battery. 4. Connect the second jumper cable
to the negative ( — ) terminal on
the booster battery. Connect theother end to the grounding strap
as shown. Do not connect this
jumper cable to any other part of the engine.
5. If the booster battery is in another vehicle, have an assistant start
that vehicle and run it at a fast idle. 6. Start your vehicle. If the starter
motor still operates slowly, check
the jumper cable connections to
make sure they have good metal-
to-metal contact.
7. Once your vehicle is running, disconnect the negative cable from
your vehicle, then from the booster battery. Disconnect the
positive cable from your vehicle,
then the booster battery.

If Your Engine Overheats

The pointer of your vehicle's temperature gauge should stay in
the midrange under most conditions.
It may go higher if you are driving up
a long steep hill on a very hot day. If
it climbs to the red mark, you should
determine the reason.

Driving with the temperature gauge
pointer at the red mark can cause serious damage to your engine.
Your vehicle can overheat for several
reasons, such as lack of coolant or a

mechanical problem. The only

indication may be the temperature

gauge climbing to or above the red mark. Or you may see steam or
spray coming from under the hood.

In either case, you should take

immediate action.
1. Safely pull to the side of the road.
Put the transmission in Neutral or
Park and set the parking brake.
Turn off the heating and cooling system and all other accessories.
Turn on the hazard warning indicators.
2. If you see steam and/or spray coming from under the hood, turn
off the engine.
3. If you do not see steam or spray, leave the engine running and
watch the temperature gauge. If the high heat is due to overloading (climbing a long, steep hill on a
hot day with the A/C running, for example), the engine should start
to cool down almost immediately. If it does, wait until the tempera-
ture gauge comes down to the mid-
point then continue driving.

NOTICE

Steam and spray from an
overheated engine can
seriously scald you.
Do not open the hood if steam
is coming out.ProCarManuals.comMain Menu Table of Contents s t

If Your Engine Overheats
4. If the temperature gauge stays at the red mark, turn off the engine.
5. Wait until you see no more signs of steam or spray, then open the

hood.

6. Look for any obvious coolant leaks, such as a split radiator hose.
Everything is still extremely hot,
so use caution. If you find a leak, it
must be repaired before you
continue driving (see Towing on
page 244).
7. If you don't find an obvious leak, check the coolant level in the
radiator reserve tank (see page 132). If the level is below the
MIN mark, add coolant to halfway
between the MIN and MAX marks.
8. If there was no coolant in the reserve tank, you may also have to
add coolant to the radiator. Let the
engine cool down until the pointer reaches the middle of the tempera-
ture gauge, or lower, before check- ing the radiator.
9. Using gloves or a large heavy cloth, turn the radiator cap
counterclockwise, without pushingdown, to the first stop. This
releases any remaining pressure in
the cooling system. After the
pressure releases, push down on
the cap and turn it until it comes
off.
10.Start the engine and set the
temperature control lever tomaximum. Add coolant to the
radiator up to the base of the filler
neck. If you do not have the
proper coolant mixture available,
you can add plain water. Remember to have the cooling
system drained and refilled with
the proper mixture as soon as you
can.

11. Put the radiator cap back on tightly. Run the engine and watch
the temperature gauge. If it goes
back to the red mark, the engine
needs repair. (See Towing on
page 244.)
12.If the temperature stays normal, check the coolant level in the
radiator reserve tank. If it has
gone down, add coolant to the MAX mark. Put the cap back on

tightly.

Removing the radiator cap

while the engine is hot can
cause the coolant to spray out,
seriously scalding you.
Always let the engine and radiator cool down before
removing the radiator cap.ProCarManuals.comMain Menu Table of Contents s t
