Owner Maintenance Checks
You should check the following items at the specified intervals. If
you are unsure of how to perform any check, turn to the page given. Engine oil level — Check every
time you fill the fuel tank. See page 123. Engine coolant level — Check the
radiator reserve tank every time
you fill the fuel tank. See page 124.
Windshield washer fluid — Check
the level in the reservoir monthly.If weather conditions cause you to
use the washers frequently, check
the reservoir each time you stop
for fuel. See page 182. Automatic transmission — Check
the fluid level monthly. See page
183.
Brakes — Check the fluid level
monthly. See page 185. Tires — Check the tire pressure
monthly. Examine the tread for
wear and foreign objects. See page

Engine Oil
Adding Oil
To add oil, unscrew and remove the engine oil fill cap on top of the valve
cover. Pour in the oil, and replace the engine oil fill cap. Tighten it securely.
Wait a few minutes and recheck the oil level. Do not fill above the upper
mark; you could damage the engine. Recommended Oil
Oil is a major contributor to your
engine's performance and longevity.
Always use a premium-grade deter- gent oil.
You can determine an oil's SAE
viscosity and Service Classification from the API Service label on the oilcontainer.
A fuel-efficient oil is recommended for your Honda. This is shown on the
API Service label by the words "Energy Conserving". This oil is
formulated to help your engine use less fuel. The API Service label also tells you
the service classification of the oil.
Always use an oil that is labeled "API Service SJ". This service rating may
include other classifications, such asCD. These additional classifications
are not a problem, as long as the
label also carries the SJ classification.

4. Install a new oil filter according to
instructions that come with it.
5. Put a new washer on the drain bolt,
then reinstall the drain bolt.
Tighten it to:
33 Ibf .

6. Refill the engine with the recom-

mended oil.

Engine oil change capacity (including filter):

5.1 US qt(4.8 l ,4.2 Imp qt)

7. Replace the engine oil fill cap. Start the engine. The oil pressure
indicator light should go out within
five seconds. If it does not, turn off
the engine and reinspect your
work.
8. Let the engine run for several minutes and check the drain bolt
and oil filter for leaks. 9. Turn off the engine, let it sit for
several minutes, then check the oil
level. If necessary, add oil to bring
the level to the upper mark on the
dipstick.

Improper disposal of engine oil can be
harmful to the environment. If yon
change your own oil, please dispose of the used oil properly. Put it in a sealed
container and take it to a recycling
center. Do not discard it in a trash bin
or dump it on the ground.

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 anothermajor-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.

RESERVE TANK

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

Cooling System

7. Pour coolant into the radiator up to the base of the filler neck. 8. Loosen the bleeder bolt on top of
the engine. Tighten it again whencoolant comes out in a steady
stream with no bubbles.
9. Refill the radiator to the base of the filler neck. Start the engineand let it run until it warms up (the
radiator cooling fan comes on at
least twice). 10. Turn off the engine. Check the
level in the radiator, add coolant if
needed. 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 fluidlevel by removing the cap and
looking at the float. It should be up
to the top of the neck. If the float is at the bottom of the neck, the
reservoir is nearly empty.
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 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.

Transmission Fluid

Automatic Transmission
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 securely as
shown in the illustration.
4. Remove the dipstick and check the fluid level. It should bebetween the upper and lowermarks. 5. If the level is below the lower
mark, add fluid into the filler hole
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 shift quality. Have the transmission
drained and refilled with Honda
ATF as soon as it is convenient.
6. Insert the dipstick all the way back into the transmission securely as
shown in the illustration.
The transmission should be drained and refilled with new fluid according
to the time and distance recommen-
dations in the maintenance schedule.

Brake and Clutch Fluid, Power Steering

Clutch System

The fluid should be between the MIN and MAX marks on the side of
the reservoir. If it is not, add brake
fluid to bring it up to that level. Use
the same fluid specified for the
brake system.
Low fluid level can indicate a leak in
the clutch system. Have this system inspected as soon as possible. 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.

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 255.)

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.
