Your vehicle does not require any oil
additives. Additives may adversely
af f ect the engine or transmission
perf ormance and durability.Open the hood, and remove the
engine oil f ill cap. Remove the oil
drain bolt and washer f rom the
bottom of the engine. Drain the oil
into an appropriate container.

Improper disposal of engine oil can be
harmf ul 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.

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 f or leaks.Always use Honda All Season
Antif reeze/Coolant Type 2. This
coolant is pre-mixed with 50 percent
antif reeze and 50 percent water.
Never add straight antifreeze or
plain water.
If Honda antif reeze/coolant is not
available, you may use another
major-brand non-silicate coolant as a
temporaryreplacement.Makesureit
is a high-quality coolant
recommended f or aluminum engines.
Continued use of any non-Honda
coolant can result in corrosion,
causing the cooling system to
malf unction or f ail. Have the cooling
system f lushed and ref illed with
Honda antif reeze/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.

Pour the coolant slowly and caref ully
so you do not spill. Clean up any spill
immediately; it could damage
components in the engine
compartment.The coolant level should be up to
the base of the f iller neck. Add
coolant if it is low.
When the radiator and engine are
cool, relieve any pressure in the
cooling system by turning the
radiator cap counterclockwise,
without pressing down.
Remove the radiator cap by
pushing down and turning
counterclockwise. Put the radiator cap back on, and
tighten it fully.
Pour coolant into the reserve tank.
Fill it to half way 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 vehicle’s
cooling system. They may not be
compatible with the coolant or

monthly during normal use.Check the f luid level with the engine
at normal operating temperature.
Park the vehicle on level ground.
Shut of f the engine.
Remove the dipstick (yellow loop)
f rom the transmission, and wipe it

Fill the reservoir with a good-quality
windshield washer f luid. This
increases the cleaning capability and
prevents f reezing in cold weather.
When you ref ill the reservoir, clean
the edges of the windshield wiper
blades with windshield washer f luid
on a clean cloth. This will help to
condition them. If the washer f luid is low, a
‘‘WASHER FLUID LOW’’ message
appears on the multi-inf ormation
display.
Insert the dipstick all the way into
the transmission as shown.
Remove the dipstick, and check
the f luid level. It should be

Do not use engine antif reeze
or a vinegar/water solution in the
windshield washer reservoir. Antif reeze
can damage your vehicle’s paint, while
a vinegar/water solution can damage
the windshield washer pump. Use only
commercially-available windshield
washer f luid.

Insert the dipstick all the way back
into the transmission securely as
shown in the illustration.
To thoroughly f lush the transmission,
the technician should drain and ref ill
it with Honda ATF-Z1, then drive the
vehicle f or a short distance. Do this
three times. Then drain and ref ill the
transmission a f inal time.
The transmission should be drained
and ref illed with new f luid when this
service is shown on a maintenance
message in the Multi-Inf ormation
Display.
If you are not sure how to add f luid,
contact your dealer. Check the brake f luid level in the
reservoirs monthly.
Replace the brake f luid every 3 years,
independent of mileage.
Always use Honda Heavy Duty
Brake Fluid DOT 3. If it is not
available, you should use only DOT 3
or DOT 4 f luid, f rom a sealed
container, as a temporary
replacement.
Using any non-Honda brake f luid can
cause corrosion and decrease the lif e
of the system. Have the brake
system f lushed and ref illed with
Honda Heavy Duty Brake Fluid
DOT 3 as soon as possible.
Brake f luid marked DOT 5 is not
compatible with your vehicle’s
braking system and can cause
extensive damage.
If the level is below the lower
mark, add f luid into the dipstick
tube to bring it to the upper mark.
Pour the f luid slowly and caref ully
so you do not spill any. Clean up
any spill immediately; it could
damage components in the engine
compartment.
Always use Honda ATF-Z1
(automatic transmission f luid). If
it’s not available, you may use a
DEXRON
III automatic
transmission f luid as a temporary
replacement. However, continued
use can affect the shift quality.
Have the transmission f lushed and
ref illed with Honda ATF-Z1 as
soon as it is convenient.
