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 f or
as long as you own it.
Unscrew and remove the engine oil
fill cap on the valve cover. Pour in
the oil slowly and caref ully so you do
not spill any. Clean up any spills
immediately. Spilled oil could
damage components in the engine
compartment. Reinstall the engine
oil f ill cap, and tighten it securely.
Wait a f ew minutes, and recheck the
oil level on the engine oil dipstick.
Do not f ill above the upper mark; you
could damage the engine. Recommended Engine Oil

The oil’s viscosity or weight is
provided on the container’s label.
Select the oil f or your vehicle
according to this chart.
An oil with a viscosity of 10W-30 is
pref erred f or optimum f uel economy
and year-round protection in your
vehicle. You may use 5W-40 oil if the
temperature in your area goes below
0°F ( 20°C).
Your vehicle does not require any oil
additives. Additives may adversely
af f ect the engine or transmission
perf ormance and durability.
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 shown on the information
display.
Always change the oil and f ilter
according to the maintenance
messages shown on the inf ormation
display. The oil and f ilter collect
contaminants that can damage your
engine if they are not removed
regularly.
Run the engine until it reaches
normal operating temperature,
then shut it off.
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.

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,
causingthecoolingsystemto
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 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.
Turn of f the engine and let it sit

Check the f luid level with the
transmission at normal operating
temperature and the vehicle sitting
on level ground. Remove the
transmission f iller bolt, and caref ully
f eel inside the bolt hole with your
f inger. The f luid level should be up
to the edge of the bolt hole. If it is
not, add Honda Manual
Transmission Fluid (MTF) until it
starts to run out of the hole. Install
the f iller bolt, and tighten it securely.If you are not sure how to check and
add f luid, contact your dealer.
The transmission should be drained
and ref illed with new f luid according
to the intervals shown on the
inf ormation display.
If Honda MTF is not available, you
may use an SAE 10W-30 or 10W-40
viscosity motor oil with the API
Certif ication seal that says ‘‘FOR
GASOLINE ENGINES’’ as a
temporary replacement. However,
motor oil does not contain the proper
additives, and continued use can
cause stiffer shifting. Replace as
soon as it is convenient.
Put a new washer on the f iller bolt,

Let the vehicle sit f or a minute.
Open the hood, and check the oil
level (see page ). An engine
very low on oil can lose pressure
during cornering and other driving
maneuvers.
If necessary, add oil to bring the
level back to the full mark on the
dipstick (see page ).
Start the engine, and watch the oil
pressure indicator. If it does not go
out within 10 seconds, turn of f the
engine. There is a mechanical
problem that needs to be repaired
bef ore you can continue driving
(see on page).
This indicator should never come on
when the engine is running. If it
starts flashing or stays on, the oil
pressure has dropped very low or
lost pressure. Serious engine
damage is possible, and you should
take immediate action.
If the charging system indicator
comes on brightly when the engine
is running, the battery is not being
charged.
Go to a service station or garage
where you can get technical
assistance. Immediately turn of f all electrical
accessories. Try not to use other
electrically operated controls such as
the power windows. Keep the engine
running; starting the engine will
discharge the battery rapidly.
Saf ely pull of f the road and shut
of f the engine. Turn on the hazard
warning lights.
