Cooling System

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 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 MAXand MIN marks. Put the cap back
on the reserve tank.
Do not add any rust inhibitors or
other additives to your vehicle's
cooling system. They may not be
compatible with the coolant or
engine components.

Replacing Engine Coolant
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 vehicle. Unless you have the tools and
knowledge, you should have this maintenance done by a skilled
mechanic. 1. Slide the heater temperature
control lever to maximum heat.Open the hood. Make sure 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.

4. Remove the reserve tank from its holder by pulling it straight up.
Drain the coolant, then put the
tank back in its holder. 5. When the coolant stops draining,
tighten the drain plug in the
bottom of the radiator.
6. Mix the recommended antifreeze with an equal amount of purifiedor distilled water in a clean
container. The cooling system capacity is:

With 5-speed manual transmission:
0.82 US gal (3.1 , 0.68 Imp gal)

With automatic transmission:

0.85 US gal (3.2 ,0.70 Imp gal)
7. Pour
coolant into the radiator up
to the base of the filler neck.

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 sideheadlight. 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 andprevents freezing in cold weather. Do not use engine antifreeze or a
vinegar/water solution in the

windshield washer reservoir.

Antifreeze can damage your vehicle's

paint, while a vinegar/water solution
can damage the windshield washer

pump.

Use only commercially-available

windshield washer fluid.
Automatic Transmission
The engine and transmission must
be at normal operating temperature
before checking the fluid level. Drivethe vehicle at least 10 miles (16
kilometers) before checking.
1. Park the vehicle 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 holeto 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 shift quality. Have the transmissiondrained 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 asshown 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). Otherwise,
change the fluid every 30,000 miles
(48,000 km).

Transmission Fluid, Brake and Clutch Fluid

5-speed Manual Transmission
Check the fluid level with the
transmission at normal operating
temperature and the vehicle 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 not
available. However, motor oil does
not contain the proper additives and
continued use can cause stiffershifting. Replace as soon as
convenient.
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 one or two reservoirs, depending on model.
They are:
Brake fluid reservoir (all models)Clutch fluid reservoir (manual transmission only)
The brake fluid in the brake system should be replaced according to the
time and distance recommendations in the maintenance 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 fluid
can 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 vehicle's
braking system and can cause extensive damage. Brake System
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.
