Improperly inf lated tires
The f ollowing f actors can lower your
vehicle’s f uel economy:
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.

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 in the first
column on page .
Independent of the maintenance messages in the multi-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 if they are noisy. 389
If you drive in dusty conditions, replace every 15,000
miles (24,000 km).
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).
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 miles (U.S.)/100,000 km (Canada).
Driving in mountainous areas at very low vehicle
speeds or trailer towing results in higher level of
mechanical (shear) stress to fluid. 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).

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 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.
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. 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. It is
highly recommended that you use
Honda motor oil in your vehicle.
Make sure the API Certif ication Seal
says ‘‘For Gasoline Engines.’’
