r Maintenanc e Check s

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 130. Engine coolant level — Check the
radiator reserve tank every time
you fill the fuel tank. See page 131 .
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 190 .
Automatic transmission — Check the fluid level monthly. See page
191.
Brakes — Check the fluid level
monthly. See page 193 .
Tires — Check the tire pressure
monthly. Examine the tread for
wear and foreign objects. See page
205.
Lights — Check the operation of
the headlights, parking lights,
taillights, high-mount brake light,

Maintenance

e Oi l

Addin g Oi l

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.
Recommende
d Oi l

Oil is a major contributor to your

engine's performance and longevity.
Always use a premium-grade deter- gent oil. It is highly recommended
that you use Genuine Honda MotorOil in your vehicle for as long as you
own it.
You can determine an oil's SAE
viscosity and Service Classification

from the API Service label on the oil container.
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.

The oil container may also display the API Certification seal. Make sureit says "For Gasoline Engines."
API CERTIFICATIO N SEA L The SAE numbers tell you the oil's
viscosity or weight. Select the oil for
your car according to this chart.
An oil with a viscosity of 5W-30 is preferred for improved fuel economyand year-round protection in your
Honda. You may use a 10W-30 oil if
the temperature in your area never
goes below 20°F (—7°C). Syntheti
c Oi l
You may use a synthetic motor oil if it meets the same requirements
given for conventional motor oil: energy conserving, a service
classification of SJ, and the proper
weight as shown on the chart. When
using synthetic oil, you must follow
the oil and filter change intervals
given in the maintenance schedule.
Additive s
Your Honda does not need any oil additives. Purchasing additives for
the engine or transmission will not
increase your car's performance or
longevity. It only increases the cost of operating your car.

Always change the oil and filter according to the time and distance (miles/kilometers) recommenda-
tions in the maintenance schedule.
The oil and filter collect contami- nants that can damage your engine if
they are not removed regularly.
Changing the oil and filter requires
special tools and access from
underneath the car. The car should
be raised on a service station-type
hydraulic lift for this service. Unless
you have the knowledge and proper equipment, you should have this
maintenance done by a skilled
mechanic.
1. Run the engine until it reaches normal operating temperature,

then shut it off.
2. Open the hood and remove the
engine oil fill cap. Remove the oildrain bolt and washer from the
bottom of the engine. Drain the oil
into an appropriate container. 3. Remove the oil filter and let the
remaining oil drain. A special
wrench (available from your Honda dealer) is required to

remove the filter.

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 dispoasl of engine oil can be

harmful to the environment. If you

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.

Coolin

Addin g Engin e Coolan t

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.

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.

Coolin
g Syste m

1. Make sure the engine and radiator are cool.
2. Turn the radiator cap counter- clockwise, without pressing down
on it, until it stops. This relieves
any pressure remaining in the

cooling system.
3. Remove the radiator cap by
pushing down and turning
counterclockwise.
4. The coolant level should be up to the base of the filler neck. Addcoolant if it is low.
5. Put the radiator cap back on.
Tighten it fully.

6. Pour coolant into the reserve tank.Fill it to halfway between the MAX
and MIN marks. Put the cap backon the reserve tank.

Do not add any rust inhibitors or other additives to your car's coolingsystem. They may not be compatible
with the coolant or engine compo-
nents.

Replacin g Engin e Coolan t
The cooling system should be completely drained and refilled with
new coolant according to the time
and distance recommendations in
the maintenance schedule. Only use Genuine Honda Antifreeze/Coolant.
Draining the coolant requires access
to the underside of the car. Unless
you have the tools and knowledge,
you should have this maintenance done by a skilled mechanic. 1. Turn the ignition ON (II). Slide
the heater temperature controllever to maximum heat. Turn offthe ignition. Open the hood. Makesure the engine and radiator are
cool to the touch.
2. Remove the radiator cap. 3. Loosen the drain plug on the
bottom of the radiator. Thecoolant will come out through the
hole in the splash cover.
