The Braking System

Your Honda is equipped with disc brakes at all four wheels. The
braking system is power-assisted to
reduce the effort needed on the
brake pedal.
Put your foot on the brake pedal
only when you intend to brake.
Resting your foot on the pedal
keeps the brakes applied lightly,
causing them to build up heat. Heat
build-up can reduce how well your
brakes work. It also keeps your
brake lights on all the time, confusing drivers behind you.
Constant application of the brakes
when going down a long hill builds
up heat and reduces their effective-
ness. Use the engine to assist the
brakes by downshifting to a lower
gear and taking your foot off the
accelerator pedal. Check your brakes after driving
through deep water. Apply the
brakes moderately to see if they feel normal. If not, apply them
gently and frequently until they do. Since a longer distance is needed to
stop with wet brakes, be extra
cautious and alert in your driving.

Brake Wear Indicators

All four brakes have audible brake
wear indicators. When the brake pads need re-placing, you will hear a distinctive
metallic "screeching" sound when
you apply the brakes. If you do not
have the brake pads replaced, they
will begin screeching all the time.
Your brakes may sometimes squeal
or squeak when you apply them
lightly. Do not confuse this with the
brake wear indicators. They make a very audible "screeching".
Brake System Design

The hydraulic system that operates
the brakes has two separate cir- cuits. Each circuit works diago-
nally across the car (the left-front
brake is connected with the right-
rear brake, etc.). If one circuit
should develop a problem, you will
still have braking at two wheels.

Four Wheel Steering, Driving in Bad Weather

At very slow speeds, the rear
wheels steer in the opposite direction to the front wheels. This
helps in maneuvers such as parallelparking and U-turns.
At higher speeds, the rear wheels
first steer in the same direction as the front wheels. This aids with
changing lanes. As you turn the
steering wheel more, the rear
wheels return to straight ahead and
then steer in the opposite direction
to the front wheels. This givesimproved handling when going
around curves at highway speeds. The rear wheels return to the
straight ahead position when you
turn off the engine. They also
return to straight ahead if you sit
still for more than two minutes
with the engine running. They
return to steering mode as soon as
you move the steering wheel or
start to drive away.
The 4WS system is self-checking.
If it detects a problem anywhere in
the system, it turns on the 4WS indicator on the instrument panel
(see page 35) and points the rear
wheels straight ahead. Your car
will then drive like a conventional car without 4WS.
Driving in Bad Weather

Rain, fog, and snow conditions re-
quire a different driving technique
because of reduced traction and
visibility. Keep your car well- maintained and exercise greater
caution when you need to drive in
bad weather. The cruise control
should not be used in these condi-

tions.

Maintenance Schedule

The Required Maintenance Schedule specifies how often you
should have your car serviced, and
what things need attention. It is
essential that your car be serviced
as scheduled to retain its high level of safety, dependability, and
emission control performance.
The services and time or mileage intervals shown in the maintenance
schedule assume you will use your
car as normal transportation for
passengers and their possessions.
You should:
Avoid exceeding your car's loadlimit. This puts excess strain on
the engine, brakes, and many
other parts of your car. The load
limit is shown on the label in the
glove box. Operate your car on reasonable
roads within the legal speed limit. Drive your car regularly over a
distance of several miles.
Always use unleaded gasoline

with the proper octane (see page

98).

Your authorized Honda dealer
knows your car best, and can provide competent, efficient
service. However, service at a
dealer is not mandatory to keep
your warranties in effect. Mainte-
nance may be done by any qualified
service facility or person who is
skilled in this type of automotive
service. Keep all the receipts as
proof of completion, and have the
person who does the work fill out
the maintenance record on page 131. Check your warranty booklet
for more information. We recommend the use of Genuine
Honda parts and fluids or their
equivalent whenever you have
maintenance done. These are the
same high-quality items that went
into your car when it was new, so you can be sure they fit and
perform flawlessly.
U.S. Cars:
Maintenance, replacement or
repair of emission control
devices and systems may be
done by any automotive re-
pair establishment or indi-
vidual using parts that are "certified" to EPA standards.

Vehicles sold in California have
slightly different maintenance

requirements. These are noted in

the Required Maintenance Sche-

dule. Other maintenance operations

are required by California regula-

tions, and condition the emission

warranty.

Engine Oil

Checking Engine Oil

Check the engine oil a couple of
minutes after shutting off the
engine. This will allow the oil to
drain down to the bottom of the
engine. Make sure the car is parked
on level ground.
1. Pull out the dipstick (orange
loop) and wipe it with a cloth orpaper towel.

2. Insert
it all the way back in its

tube.

3. Pull
it out again and look at the
oil level at the end of the dipstick.
If it is between the upper and
lower marks, the level is correct.
Add oil if the level is at or below
the lower mark.
Adding

To add oil, unscrew and remove the
oil filler cap on top of the valve
cover. Pour in the oil, and replace
the filler 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.

7. Replace the oil filler 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. 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.

The oil and filter should be chang-

ed every 6 months or 12,000 km

(7,500 miles), whichever comes first.

Under severe driving conditions,

they should be changed every 3
months or 6,000 km (3,750 miles).

See page 130 for a description of

severe driving conditions.

Cooling System

Checking the Coolant Level

Check the level of the engine
coolant by looking at the radiator
reserve tank next to the battery. If
the level is at or below the MIN line, add coolant to bring it up to the
MAX line. This coolant should
always be a mixture of 50%
antifreeze and 50% water. Never
add straight antifreeze or plain
water. Always use Genuine Honda Anti-
freeze/Coolant. The cooling system contains many aluminum compo-
nents which can corrode if an
improper antifreeze is used. Some
antifreeze, even though labeled as
safe for aluminum parts, may not
provide adequate protection.
Adding Radiator Coolant

If the reserve tank is completely
empty, you should also check the
coolant level in the radiator.
1. Make sure the engine and radiator are cool.

10.Turn off the engine. Check the
level in the radiator, add coolant
if needed. Install the radiator cap,
tighten it fully.

11.Fill the
reserve tank to the MAX

mark. Install the reserve tank
cap.

Windshield Washers
Chec
k 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 gas.
The windshield washer reservoir is
located behind the left headlight.
Check the reservoir's fluid level 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 car's paint, while a vinegar/water
solution can damage the windshield
washer pump.
Use only commercially-available
windshield washer fluid.
