Air Conditioning System
Standard on U.S. EX model

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 makesure 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 234.)
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.

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 to
start. You may hear a clicking sound
or series of clicks, or nothing at all.
Check these things:
Check the transmission interlock.
If you have a manual transmission,
the clutch pedal must be pushed
all the way to the floor or the
starter will not operate. With an
automatic transmission, it must be
in Park or Neutral.
Turn the ignition switch to ON (II).
Turn on the headlights and check their brightness. If the headlights
are very dim or don't light at all,
the battery is discharged. See

Jump Starting on page 213.
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 ignition switch or starter motor. You will
need a qualified technician to determine the problem. (See
Emergency Towing on page 227).

If the headlights dim noticeably or
go out when you try to start the engine, either the battery is dis-
charged or the connections are
corroded. Check the condition of
the battery and terminal connec-
tions (see page 173). You can
then try jump starting the vehicle
from a booster battery (see page 213).

If Your Engine Won't Start, Jump Starting

The Starter Operates Normally In this case, the starter motor'sspeed 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 121.
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 223).
If you find nothing wrong, you will
need a qualified technician to find
the problem. See Emergency Towing on page 227. 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 with anautomatic transmission 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 150). 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.

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 startthat 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

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 Emergency
Towing on page 227).
7. If you don't find an obvious leak, check the coolant level in the
radiator reserve tank (see page112). 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 coolingsystem 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 engineneeds repair. (See EmergencyTowing on page 227).
12.1f 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.

Taking Care of the Unexpected
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.Main Menu Table of Contents s t

Low Oil Pressure Indicator

This indicator should light when the ignition switch is ON (II), and go out
after the engine starts. It should
never come on when the engine is
running. If it starts flashing, it indicates that the oil pressuredropped very low for 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.
Running the engine with low oil
pressure can cause serious mechanical damage almost immediately. Turn offthe engine as soon as you can safety get
the vehicle stopped.

1. Safety pull off the road and shut off the engine. Turn on the hazard
warning indicators.
2. Let the vehicle sit for a minute. Open the hood and check the oil
level (see page 111). 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.

3. If necessary, add oil to bring the level back to the full mark on thedipstick (see page 155). 4. Start the engine and watch the oil
pressure indicator. If the lightdoes not go out within ten seconds,
turn off the engine. There is a
mechanical problem that needs to
be repaired before you can continue driving (See Emergency
Towing on page 227).

Malfunction Indicator Lamp

This indicator comes on for a few seconds when you turn the ignition
switch ON (II). If it comes on at any
other time, it indicates one of the
engine's emissions control systems
may have a problem. Even though
you may feel no difference in your
vehicle's performance, it can reduce
your fuel economy and cause your
vehicle to put out excessive emissions. Continued operation may
cause serious damage. If you have recently refueled your
vehicle, the cause of this indicator coming on could be a loose or
missing fuel fill cap. Check the capand tighten it until it clicks. Replace
the fuel fill cap if it is missing.
Tightening the cap will not make the indicator turn off immediately; it
takes three driving trips.
If the indicator remains on past three
driving trips, or the fuel cap was not
loose or missing, have the vehicle checked by the dealer as soon as
possible. Drive moderately until thedealer has inspected the problem.
Avoid full-throttle acceleration and driving at high speed. You should also have the dealer
inspect your vehicle if this indicatorcomes on repeatedly, even though it
may turn off as you continue driving.
If you keep driving with the malfunc- tion indicator lamp on, you can damage
your vehicle's emission controls and engine. Those repairs may not be
covered by your vehicle's warranties.

Fuses

Vehicles equipped with ABS have a third fuse box for the ABS. It is in
the engine compartment on the
passenger's side.
Checking and Replacing Fuses

If something electrical in your
vehicle stops working, the first thing
you should check for is a blown fuse. Determine from the chart on pages 198 and 199, or the diagram on the
fuse box lid, which fuse or fuses control that component. Check those
fuses first, but check all the fuses
before deciding that a blown fuse is not the cause. Replace any blown
fuses and check the component's
operation.

1. Turn the ignition switch to LOCK (0). Make sure the headlights and
all other accessories are off.
2. Remove the cover from the fuse box. 3. Check each of the large fuses in
the under-hood fuse box bylooking through the top at the wire
inside. Removing these fuses
requires a Phillips-head screw-
driver.
