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 not
available, 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 cooling
system to malfunction or fail. Have
the cooling system flushed and
refilled with Honda antifreeze/
coolant as soon as possible. If the reserve tank is completely
empty, you should also check the
coolant level in the radiator.

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.

10. Turn off the engine. Check the level in the radiator, add coolant ifneeded. Install the radiator cap,
and tighten it fully.
11. Fill the reserve tank to the MAX mark. Install the reserve tank cap. Windshield Washers

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 side
headlight. 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 and
prevents freezing in cold weather.
Do not use engine antifreeze or a vinegar/water solution in thewindshield washer reservoir.
LEVEL GAUGE

Antifreeze can damage your vehicle's

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

pump.

Use only commercially-available

windshieId washer fluid.

Automatic Transmission Fluid

Check the fluid level with the engine
at normal operating temperature. 1. Park the vehicle on level ground. Shut off the engine.
2. Remove the dipstick (yellow loop) from the transmission and wipe it
with a clean cloth. 3. Insert the dipstick all the way into
the transmission.
4. Remove the dipstick and check the fluid level. It should bebetween the upper and lower
marks.
5. If the level is below the lower
mark, add fluid into the tube to
bring it to the upper mark. Always use Honda Premium Formula
Automatic Transmission Fluid (ATF). If it is not available, you
may use a DEXRON ®
III
automatic transmission fluid as a
temporary replacement. However, continued use can affect shiftquality. Have the transmission
drained and refilled with Honda
ATF as soon as it is convenient.
6. Insert the dipstick all the way back in the transmission.
The transmission should be drained and refilled with new fluid according
to the time and distance recommen- dations in the maintenance schedule.

Power Steering
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 Power
Steering Fluid. If it is not available,
you may use another power steering fluid as an emergency replacement.However, continued use can cause
increased 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

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.

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.
