Cooling System

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 and
50 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.

cause the coolant to spray out,
seriously scalding you.

Always let the engine and radiator cool down before

removing the radiator cap.Main Menu Table of Contents s t

Cooling System

1. Make sure the engine and radiator are cool.
2. Turn the radiator cap counter- clockwise, without pressing downon it, until it stops. This relieves
any pressure remaining in the
cooling system.
3. Remove the radiator cap by pushing down and turningcounterclockwise.
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 back
on the reserve tank.
Do not add any rust inhibitors or
other additives to your car's cooling
system. They may not be compatible
with the coolant or engine compo-
nents.

Replacing Engine Coolant

The cooling system should be completely drained and refilled with
new coolant according to the timeand 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). Turnthe temperature control dial to
maximum heat. Turn off the
ignition and remove the key. Open
the hood. Make sure the engineand radiator are cool to the touch.
2. Remove the radiator cap. 3. Loosen the drain plug on the
bottom of the radiator. The
coolant will come out through the
hole in the splash cover.
(U.S.: Si model, Canada: SiR model)
Remove the drain bolt and washer
from the engine block.

Windshield Washers, Transmission Fluid

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 fluid
level by removing the cap and
looking at the level gauge attached
to
the cap.
Fill the reservoir with a good-quality
windshield washer fluid. This increases the cleaning capability and
prevents freezing in cold weather.
WINDSHIELD WASHER RESERVOIR

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.
The engine and transmission must
be at normal operating temperature
before checking the fluid level. Drive
the vehicle at least 10 miles (16
kilometers) before checking.
1. Park the car on level ground. Shut off the engine. For accurate
results, wait at least 60 seconds,
and no more than 90 seconds,
after shutting off the engine to
check the fluid level.

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 asshown in the illustration.
4. Remove the dipstick and check the fluid level. It should be
between the upper and lower
marks. 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 shiftquality. Have the transmission
drained and refilled with Honda
ATF as soon as it is convenient.

HX model (CVT) only:

Use Genuine Honda CVT fluid
only. Using other fluids can affect
transmission operation and may
reduce transmission life. 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.

HX model (CVT) only:

If you drive at high speeds in high
(90° F/32°C and above)

temperatures, the transmission fluid should be changed every 15,000
miles (24,000 km).

FILLER BOLT

Correct level
Check the fluid level with the
transmission at normal operating
temperature and the car sitting on
level ground. Remove the
transmission filler bolt and carefully
feel inside the bolt hole with your
finger. The fluid level should be up to the edge of the bolt hole. If it is
not, add Genuine Honda Manual
Transmission Fluid (MTF) until it starts to run out of the hole. Reinstall
the filler bolt and tighten it securely. If Honda MTF is not available, you
may use an API service SG, SH or SJ
grade motor oil with a viscosity of SAE 10W-30 or 10W-40 as a
temporary replacement. An SG grade is preferred, but an SH or SJ
grade may be used if SG is notavailable. However, motor oil does
not contain the proper additives and
continued use can cause stiffer shifting. Replace as soon asconvenient.
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
Check the fluid level in the reser-
voirs monthly. There are up to two reservoirs, depending on the model.
They are:
Brake fluid reservoir (all models) Clutch fluid reservoir
(manual transmission only)
The brake fluid should be replaced according to the time and distance
recommendations in the mainte- nance schedule.

Brake and Clutch Fluid

Always use Genuine Honda DOT 3 brake fluid. If it is not available, you should use only DOT 3 or DOT 4
fluid, from a sealed container, as a temporary replacement. However,
the use of any non-Honda brake fluidcan cause corrosion and decrease
the life of the system. Have the
brake system flushed and refilled
with Honda DOT 3 brake fluid as soon as possible.
Brake fluid marked DOT 5 is not
compatible with your car's braking system and can cause extensive

damage.
Brake System

MIN

The fluid level should be between the MIN and MAX marks on the sideof the reservoir. If the level is at or
below the MIN mark, your brake system needs attention. Have the
brake system inspected for leaks or
worn brake pads.
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 PowerSteering 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 powersteering 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.
