Cooling System

Adding Engine Coolant

If the coolant level in the reserve
tank is at or below the MIN line, add coolant to bring it up to the MAX line.
Inspect the cooling system for leaks.
This coolant should always be a mixture of 50 percent antifreeze and50 percent water. Never add straight
antifreeze or plain water. Always use Genuine Honda
antifreeze/coolant. If it is notavailable, you may use another
major-brand non-silicate coolant as a
temporary replacement. Make sure it is a high-quality coolant
recommended for aluminum engines.
However, continued use of any non-Honda coolant can result in
corrosion, causing the coolingsystem to malfunction or fail. Have
the cooling system flushed and
refilled with Honda antifreeze/ coolant as soon as possible.
If the reserve tank is completelyempty, you should also check the
coolant level in the radiator.

RESERVE TANK

Maintenance

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

8. Start the engine and let it run until it warms up (the radiator cooling
fan comes on at least twice).
9. Turn off the engine. Check the level in the radiator, add coolant ifneeded. Install the radiator cap,
and tighten it fully.
10.Fill the reserve tank to the MAXmark. Install the reserve tank cap.

Windshield Washers, Transmission Fluid

Check the level in the windshield
washer reservoir at least monthly during normal usage. In bad weather,
when you use the washers often, check the level every time you stop

for fuel.

The windshield washer reservoir is located behind the driver's sideheadlight. Check the reservoir's fluid
level by removing the cap and
looking at the level gauge attached
to the cap.
Fill the reservoir with a good-quality
windshield washer fluid. This increases the cleaning capability andprevents freezing in cold weather. Do not use engine antifreeze or a
vinegar/water solution in the

windshield washer reservoir.

Antifreeze can damage your vehicle's

paint, while a vinegar/water solution
can damage the windshield washer

pump.

Use only commercially-available

windshield washer fluid.
Automatic Transmission
The engine and transmission must
be at normal operating temperature
before checking the fluid level. Drivethe vehicle at least 10 miles (16
kilometers) before checking.
1. Park the vehicle on level ground. Shut off the engine. For accurate
results, wait at least 60 seconds, and no more than 90 seconds,
after shutting off the engine to
check the fluid level.

Power Steering

On DX model with automatic-

transmission, HX and EX models in the
U.S., and DX and Si models in Canada

Check the level when the engine is
cold. Look at the side of the
reservoir. The fluid should be
between the UPPER LEVEL and
LOWER LEVEL. If it is below the LOWER LEVEL, add power steering
fluid to the UPPER LEVEL.
Always use Genuine Honda PowerSteering Fluid. If it is not available,
you may use another power steering fluid as an emergency replacement.
However, continued use can causeincreased wear and poor steering in
cold weather. Have the power
steering system flushed and refilled
with Honda PSF as soon as possible. A low power steering fluid level can
indicate a leak in the system. Check
the fluid level frequently and have
the system inspected as soon as

possible.

Turning the steering wheel to full left
or right lock and holding it there can
damage the power steering pump.

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.

Taking Care of the Unexpected

This section covers the more- common problems that motoristsexperience with their vehicles. It
gives you information about how to safely evaluate the problem and what
to do to correct it. If the problem has stranded you on the side of the road,
you may be able to get going again. If not, you will also find instructionson getting your vehicle towed. Compact Spare Tire....................... 206

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.

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.
