The f ollowing f actors can lower your
vehicle’s f uel economy:
Aggressive driving (hard
acceleration and braking)
Excessive idling, accelerating and
braking in stop-and-go traf f ic
Cold engine operation (engines
aremoreefficientwhenwarmed
up)
Driving with a heavy load or the
air conditioner running
Improperly inf lated tires
A properly maintained vehicle
maximizes f uel economy. Poor
maintenance can signif icantly reduce
f uel economy. Always maintain your
vehicle according to the maintenance
messages displayed on the
inf ormation display (see on page ).
For example: An under-inf lated tire increases
‘‘rolling resistance,’’ which reduces
f uel economy.
It puts a heavier
load on the engine, increasing f uel
consumption. In
particular, a build-up of snow or
mud on your vehicle’s underside
adds weight and rolling resistance.
Frequent cleaning helps your f uel
economy.
Rapid
acceleration, abrupt cornering,
and hard braking increase fuel
consumption. Aerodynamic drag has a big ef f ect
on f uel mileage at speeds above 45
mph (75 km/h). Reduce your
speed and you reduce the drag.
Trailers, car top carriers, roof
racks and bike racks are also big
contributors to increased drag.
If your vehicle has a
manual transmission, you can
boost your f uel economy by up
shif ting as early as possible. Idling
results in 0 miles per gallon.
Combine several short trips into
one. A warmed-up engine is more
f uel ef f icient than a cold one. The A/C
puts an extra load on the engine
which makes it use more f uel. Use
the f resh-air ventilation when
possible.

If you have the required service
done but do not reset the display, or
reset the display without doing the
service, the system will not show the
proper maintenance intervals. This
canleadtoseriousmechanical
problems because you will no longer
have an accurate record of when
maintenance is needed.
Your authorized Honda dealer
knows your vehicle best and can
provide competent, ef f icient service. U.S. Vehicles:
According to state and federal
regulations, f ailure to perf orm
maintenance on the items marked
with will not void your emissions
warranties. However, all
maintenance services should be
perf ormed in accordance with the
intervals indicated by the
inf ormation display.
However, service at a dealer is not
mandatory to keep your warranties
in effect. Maintenance may be done
by any qualif ied service f acility or
person who is skilled in this type of
automotive service. Make sure to
have the service f acility or person
reset the display as previously
described. Keep all receipts as proof
of completion, and have the person
who does the work f ill out your
Honda Service History or Canadian
Maintenance Log. Check your
warranty booklet f or more
inf ormation.
We recommend the use of Honda
parts and f luids whenever you have
maintenance done. These are
manuf actured to the same high-
quality standards as the original
components, so you can be conf ident
of their perf ormance and durability.

If the message ‘‘SERVICE dUE NOW’’ does not appear more than 12 months
after the display is reset, change the engine oil every year.
See information on maintenance and emissions warranty on page .Independent of the maintenance messages in the information display,
replace the brake fluid every 3 years.
Inspect idle speed every 160,000 miles (256,000 km).
Adjust the valves during services A, B, 1, 2, or 3 only if they are noisy.
NOTE: 1:
244
If you drive primarily in urban areas that have high
concentrations of soot in the air from industry and from diesel-
powered vehicles, replace every 15,000 miles (24,000 km).
Driving in mountainous terrain at very low vehicle speeds,
towing a trailer, or driving when fully loaded results in higher
transmission and transfer temperatures. This requires
transmission and transfer fluid changes more frequently
than recommended by the Maintenance Minder.
If you regularly drive your vehicle under these conditions, have
the transmission and transfer fluid changed every 30,000 miles
(48,000 km).
If you drive regularly in very high temperatures (over 110°F,
43°C), in very low temperatures (under-20°F, -29°C), or towing a
trailer, replace every 60,000 mile (U.S.)/100,000 km (Canada)
Driving in mountainous terrain at very low vehicle speeds,
towing a trailer, or driving when fully loaded causes more
mechanical (shear) stress and fluid deterioration. This requires
differential fluid changes more frequently than recommended
by the Maintenance Minder. If you regularly drive your vehicle
under these conditions, have the differential fluid changed at
7,500 miles (12,000 km), then every 15,000 miles (24,000 km).

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 vehicle to
improve cold weather starting and
f uel economy.
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
