Make sure the API Certif ication Seal
says ‘‘For Gasoline Engines’’.
Oil is major contributor to your
engine’s perf ormance and longevity.
Always use a premium-grade
detergent oil displaying the API
Certif ication Seal. This seal indicates
the oil is energy conserving, and that
it meets the American Petroleum
Institute’s latest requirements. It is
highly recommended that you use
Honda motor oil in your vehicle.
Unscrew and remove the engine oil
fill cap on top of the valve cover.
Pour in the oil slowly and caref ully so
you do not spill. Clean up any spills
immediately. Spilled oil could
damage components in the engine
compartment.
Install the engine oil f ill cap, and
tighten it securely. Wait a f ew
minutes, and recheck the oil level.
Do not f ill above the upper mark; you
could damage the engine. The oil’s viscosity or weight is
provided on the container’s label.
5W-20 oil is f ormulated f or year-
round protection of your vehicle, to
improve cold weather starting and
f uel economy.

µAlways change the oil and f ilter
according to the recommendations in
the maintenance schedule. The oil
and f ilter collect contaminants that
can damage your engine if they are
not removed regularly.
Changing the oil and f ilter requires
special tools and access f rom
underneath the vehicle. The vehicle
should be raised on a service station-
type hydraulic lif t f or this service.
Unless you have the knowledge and
proper equipment, you should have
this maintenance done by a skilled
mechanic.
Run the engine until it reaches
normal operating temperature,
then shut it off.
You may use a synthetic motor oil if
it meets the same requirements
given f or a conventional motor oil: it
displays the API Certif ication Seal
and it is the proper weight. You must
f ollow the oil and f ilter change
intervals given in the maintenance
schedule.
An oil with a viscosity of 5W-30 is
pref erred f or improved f uel economy
and year-round protection in your
vehicle. You may use a 10W-30 oil if
the temperature in your area never
goes below 20°F ( 7°C). Your vehicle does not require any oil
additives. Additives may adversely
af f ect your engine’s or transmission’s
perf ormance and durability.

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 reserve tank is completely
empty, you should also check the
coolant level in the radiator.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.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.Pour coolant into the reserve tank.
Fill it to half way between the MAX
and MIN marks. Put the cap on
the reserve tank. Put the radiator cap on, and
tighten it fully. Pourthecoolantslowlyand
caref ully so you do not spill. Clean
up any spill immediately; it could

DIPSTICKDo 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.

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.Insert the dipstick all the way back
into the transmission securely as
shown in the illustration.
The transmission should be drained
and ref illed with new f luid according
to the time and distance recommen-
dations in the maintenance schedule.
If youarenotsurehowtoaddfluid,
contact your dealer.
If the level is below the lower
mark, remove the f ill plug and add
f luid to bring it to the upper mark.
Pour the f luid slowly and caref ully
so you do not spill. Clean up any
spill immediately; it could damage
components in the engine
compartment.
Always use Honda ATF-Z1
(Automatic Transmission Fluid). If
it’s not available, you may use a
DEXRON

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.
Insert the dipstick all the way into
