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: Rapid
acceleration, abrupt cornering,
and hard braking increase fuel
consumption.
If your vehicle has a
manual transmission, you can
boost your f uel economy by up
shif ting as early as possible.
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.
Idling
results in 0 miles per gallon.
An underinf 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.

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
