2000 HONDA PRELUDE check engine

Th
e Brakin g Syste m

Your Honda is equipped with disc brakes at all four wheels. A powerassist helps reduce the effort needed
on the brake pedal. The ABS helps
you retain steering control when
braking very hard.
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. Brak
e Wea r Indicator s
All four brakes have audible brake wear indicators.
When the brake pads need replacing,
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."

Driving

Activ
e Torqu e Transfe r Syste m
Type SH only
Your Honda is equipped wit
h an
Active Torque Transfer System (ATTS). Under certain driving
conditions, the ATTS enhances the car's cornering performance by
transferring some torque between
the inside and outside front wheels during a turn.
Based on steering wheel turn angle,
lateral acceleration, and engine
power, the ATTS regulates the driving force to each drive wheel
through an electronically-controlled
hydraulic system and two sets of clutches and gears.
Important Safety Information

Th e ATT S canno t preven t

skiddin g if yo u ente r a corne r to o
fast . It has almost no effect on

braking and vehicle speed.
It is still your responsibility to drive
at reasonable speeds and to leave a
sufficient margin of safety.
ATTS Indicator

The Active Torque Transfer System (ATTS) is self-checking. If a problem
is detected in the system, the ATTS
indicator on the instrument panel
comes on.

If this happens, take the car to your Honda dealer to have it checked.
With the indicator on, your car will corner normally, but you will not
have active torque transfer.

ATT
S INDICATO R

Towin
g a Traile r

Your Honda has been designed primarily to carry passengers and
their cargo. You can use it to tow a
trailer if you carefully observe the
load limits, use the proper equipment,and follow the guidelines in this

section.

Loa d Limit s Tota
l Traile r Weight : The total
weight of the trailer and everything loaded in it must not
exceed 1,000 Ibs (450 kg). Towing
a load that is too heavy can
seriously affect your vehicle's
handling and performance. It can also damage the engine anddrivetrain. Tongu
e Load : The weight that
the tongue of a fully-loaded trailer
puts on the hitch should be
approximately 10 percent of the
trailer weight. Too little tongue
load can make the trailer unstable and cause it to sway. Too much
tongue load reduces front-tire
traction and steering control.
To achieve a proper tongue load, start by loading 60 percent of the
load toward the front of the trailer and 40 percent toward the rear, then
readjust the load as needed.
Gros
s Vehicl e Weigh t Ratin g

(GVWR) :

The total weight of the vehicle, all occupants, all cargo, and the
tongue load must not exceed: 3,835 Ibs (1,740 kg)
Gros
s Axl e Weigh t Ratin g

(GAWR) :

The total weight of the vehicle, all occupants, all cargo, and the
tongue load must not exceed:
2,160 Ibs (980 kg)
on the front axle
1,685 Ibs (765 kg)
on the rear axle

Drivin g
Exceeding load limits or
improperly loading your vehicle
and trailer can cause a crash in
which you can be seriously injured or killed.
Check the loading of your
vehicle and trailer carefully before starting to drive.

This section explains why it is important to keep your car well
maintained and to follow basic
maintenance safety precautions.
This section also includes Maintenance Schedules for normal
driving and severe driving conditions,
a Maintenance Record, and instruc-
tions for simple maintenance tasks
you may want to take care of
yourself.
If you have the skills and tools to per-
form more complex maintenance
tasks on your Honda, you may want to purchase the Service Manual. See
page 279 for information on how toobtain a copy, or see your Honda

dealer.

Owne
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,
turn signals, brake lights, and license plate lights monthly. See

page 211.

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.

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:

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 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
g Syste m

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.
