Engine Oil and Filter

Checking

Check the engine oil a couple of minutes after shutting the engine
off, with the car parked on level ground. Remove the dipstick and wipe it clean. Reinsert it all the way down, then pull it out and read
the level. The level should be between the upper and lower marks.

FILLER CAP

Adding
If the level has dropped close to the lower mark, add oil until it is
even with the upper mark. 1 .Turn the oil filler cap counterclockwise to remove. Add oil, then check the level again. Do not overfill.
2. Reinstall the cap and twist clockwise until it stops.

CAUTION:
Be sure the oil filler cap is correctly replaced before starting the

engine.
Engine oil is a major factor affecting the performance and

service life of the engine; you should use only a premium quality

detergent oil labeled SG grade.
LOOK FOR THIS LABEL
ON THE OIL CONTAINER

Use the proper viscosity oil for the
climate in which you drive:
Some oil labels may also include additional designations of quality
such as CC or CD. However, these are acceptable only when
used together with SG.
NOTE:

5W-30 viscosity
oil is recommended for improved fuel economy.

Fuel Efficient Oil
For the best fuel economy from your car, it is recommended that
you use a fuel efficient SG oil. This oil is usually identified by the words such as: "Energy Conserving II," "Gas Saving," and "Fuel
Saving," etc.
Changing Oil and FilterEngine oil and filter should be changed together every 6 months or

7,500 miles (12,000 km), whichever occurs first. The filter is on the

engine block, below the intake manifold.

CAUTION:

The oil filter cannot easily be removed from above the engine.For this reason it is recommended
that the oil filter change be done by a skilled mechanic.

1. Start the car to warm up the
engine, then shut it off.

2. Remove the engine oil filler cap and drain bolt, and drain the oil. ENGINE OIL DRAIN BOLT
A warmed-up engine and the oil in it are hot; be careful not to burn
yourself.
3. Remove the oil filter and let the remaining oil drain out.
4. Install a new fitter according to
instructions on or with the filter.

If the level is between the MIN and MAX marks on the dipstick
add a 50/50 solution of antifreeze and water to bring it up to MAX. If there is no coolant visible on the dipstick, the cooling system
should be checked for leaks and repaired if necessary. Coolantmust then be added to the radiator.

CAUTION:

Radiator coolant will damage paint. Quickly rinse any spilled

coolant from painted surfaces.

Wait until the engine is cool, then turn the radiator cap counterclock-wise until it stops. DO NOT PRESS DOWN WHILE TURNING THECAP. After any remaining pressure has been relieved, remove the
cap by pressing down and again turning it counterclockwise. Add
enough coolant to fill the radiator, and reinstall the cap. Be sure to
tighten it securely. Fill the reserve tank up to the MAX mark with
the engine cold.

Maintenance
1. Check the freeze protection level of the coolant with a hydrometer.
2. Keep the front of the radiator free of dirt and debris.

3. Check hoses and hose clamps regularly.

BRAKE FLUID RESERVOIR
Brake Fluid
Check the fluid level in the brake
fluid reservoir periodically; it should be between the MAX and MINmarks on the reservoir.If the level is near the MIN mark, add
fluid to raise it to the MAX mark. Do not overfill, Use only brake fluid
manufactured to DOT 3 or DOT 4
specifications (see reservoir cap)
from a seated container. Follow the manufacturer's instructions printed
on the can.
NOTE:
A low brake fluid level may be an indication of brake pad wear or of
brake fluid leakage. You should have your brakes checked if the
brake fluid level in the reservoir is low before refilling it.
CAUTION:
The arrow on the reservoir cap must be pointing forward after the cap is installed. Make sure the brake warning switch wiring doesn't
get caught between the cap and top edge of the reservoir.
ANTI LOCK
BRAKE FLUIDRESERVOIR
Anti Lock Brake Fluid (Si with ALB)
Check the fluid level in the ALB
reservoir periodically.

To check, drive the car for a few

minutes to equalize fluid pressure in
the system.
The level should be between the

MAX and MIN marks on the

reservoir. If the level is near the MIN
mark, add fluid to raise it to the
MAX mark.
Do not overfill. Use only brake fluid
manufactured to DOT 3 or DOT 4

specifications from a sealed

container.

Follow the manufacturer's

instructions printed on the can.
If the level is more than 10 mm (0.4 in) above the MAX mark, it may
indicate a malfunction of ALB system. Have an authorized Honda
dealer check the system as soon as possible.ProCarManuals.comMain Menu t s
