To determine the correct cargo and
luggage load limit:
Locate the statement, ‘‘the
combined weight of occupants and
cargo should never exceed 850 lbs
(395 kg)’’ on your vehicle’s placard
(on the driver’s doorjamb).
Determine the combined weight
of the driver and passengers that
will be riding in the vehicle.
(Five is seating capacity of your
vehicle.)
Subtract the combined weight of
the driver and passengers f rom
850 lbs (395 kg).
The resulting f igure equals the
available load capacity. Store or secure all items that could
be thrown around and hurt
someone during a crash.
Be sure items placed on the f loor
behind the f ront seats cannot roll
under the seats and interf ere with
the pedals or seat operation.
Keep the glove box closed while
driving. If it is open, a passenger
could injure their knees during a
crash or sudden stop.
For example, if there will be f our 150
lbs (70 kg) occupants in your vehicle,
the amount of available cargo and
luggage load capacity is 250 lbs (115
kg).
4 150 lbs (70 kg) = 600 lbs (280
kg)
850 lbs (395 kg) 600 lbs (280 kg) =
250 lbs (115 kg)
The maximum load f or your vehicle
is 850 lbs (395 kg). This f igure
includes total weight of all occupants,
cargo, and accessories.
Determine the combined weight
of accessories, luggage, and cargo
beingloadedinthevehicle.The
weight may not saf ely exceed the
available cargo and luggage load
capacity calculated in step 4.Do not put any items on top of the
trunk panel. They can block your
view and be thrown around the
vehicle during a crash.

Oil is a major contributor to your
engine’s perf ormance and longevity.
Always use a premium-grade 5W-20
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.Honda Motor Oil is the pref erred
5W-20 lubricant f or your vehicle. It is
highly recommended that you use
Honda Motor Oil in your vehicle f or
optimum engine protection. Make
sure the API Certif ication Seal says
‘‘For Gasoline Engines’’.
The oil viscosity or weight is
provided on the container’s label.
5W-20 oil is f ormulated f or year-
round protection of your Honda to
improve cold weather starting and
f uel economy.
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.

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
with a clean cloth.
Insert the dipstick all the way into
the transmission securely. Remove the dipstick and check
the f luid level. It should be
between the upper and lower
marks.
If the level is below the lower
mark, add f luid into the f iller hole
to bring it to the upper mark.Always use Honda ATF-Z1
(Automatic Transmission Fluid). If
it’s not available, you may use a
DEXRON
III automatic
transmission f luid as a temporary
replacement. However, continued
use can af f ect the shif t quality.
Have the transmission flushed and
ref illed with Honda ATF-Z1 as
soon as it is convenient.
Insert the dipstick all the way back
in the transmission.
The transmission should be drained
and ref illed with new f luid according
to the time and distance recommen-
dations in the maintenance schedule. 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.

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.
The transmission should be drained
and ref illed with new f luid according
to the time and distance recommen-
dations in the maintenance schedule.
In very high temperatures
(over 110°F, 43°C).
In very low temperatures
(under 20°F, 29°C).
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 Transmis-
sion Fluid (MTF) until it starts to
run out of the hole. Reinstall the
f iller bolt and tighten it securely. The timing belt should be replaced
at the intervals shown in the
maintenance schedule. Replace the
belt at 60,000 miles (100,000 km) if
you regularly drive your vehicle in
one or more of these conditions:
