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: 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.
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.

Record the total gallons (liters) needed to ref ill.
Follow one of the simple calculations above.
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.
Combine several short trips into

Direct calculation is the
recommended source of inf ormation
about your actual f uel economy.
Using f requency of f ill-ups or taking

accurate measures of f uel economy.

Removing parts f rom your vehicle,
or replacing components with
non-Honda components could
seriously af f ect your vehicle’s
handling, stability, and reliability.
Herearesomeexamples:If you plan to modif y your vehicle,
consult your dealer.Modif ying your steering wheel or
any other part of your vehicle’s
saf ety systems could make the
systems inef f ective.
Larger or smaller wheels and tires
can interf ere with the operation of
your vehicle’s anti-lock brakes and
other systems.
Non-Honda wheels, because they
are a universal design, can cause
excessive stress on suspension
components and will not be
compatible with the tire pressure
monitoring system (TPMS).
Raising your vehicle with a
non-Honda suspension kit can
af f ect the handling and stability.
Lowering the vehicle with a non-
Honda suspension kit that
signif icantly reduces ground
clearance can allow the
undercarriage to hit speed bumps
or other raised objects, which
could cause the airbags to deploy.

Steps f or Determining Correct Load
Limit Locate the statement ‘‘The
combined weight of occupants and
cargo should never exceed XXX
kg or XXX lbs.’’ on your vehicle’s
placard.
Determine the combined weight
of the driver and passengers that
will be riding in your vehicle.
Subtract the combined weight of
the driver and passengers f rom
XXX kg or XXX lbs. The resulting f igure equals the
available amount of cargo and
luggage load capacity. For
example, if the ‘‘XXX’’ amount
equals 1,400 lbs. and there will be
f ive 150 lb. passengers in your
vehicle, the amount of available
cargo and luggage load capacity is
650 lbs.
(1,400 750 (5 150) = 650 lbs.)
Determine the combined weight
of luggage and cargo being loaded
on the vehicle. That weight may
not saf ely exceed the available
cargo and luggage load capacity
calculated in Step 4.
If yourvehiclewillbetowinga
trailer, load f rom your trailer will
be transf erred to your vehicle.
Consult this manual to determine
how this reduces the available
cargo and luggage load capacity of
your vehicle.
See Tire And Loading Inf ormation
label attached to the driver’s
doorjamb.
The maximum load f or your vehicle
is 400 lbs (181 kg) f or U.S. vehicles,
and 185 kg for Canadian vehicles.
This f igure includes the total weight
of all occupants, cargo, and
accessories.
