Fuel economy is not a f ixed number.
It varies based on driving conditions,
driving habits, and vehicle condition.
Theref ore, it is not possible f or one
set of estimates to predict f uel
economy precisely f or all drivers in
all environments.
Represents urban
driving in light traf f ic. A range of
miles per gallon achieved is also
provided. The EPA f uel economy estimates
shownintheexampletotheright
are a usef ul tool f or comparison
when buying a vehicle. EPA
estimates include:
Represents a combination of city and
highway driving. The scale
represents the range of combined
f uel economy f or other vehicles in
the class.
Represents a
mixture of rural and interstate
driving, in a warmed-up vehicle,
typical of longer trips in f ree-f lowing
traf f ic. A range of miles per gallon achieved is also provided.
Provides an estimated annual f uel
cost, based on 15,000 miles (20,000
km) per year multiplied by the costpergallon(basedonEPAfuelcost
data) divided by the combined f uel

Aggressive driving (hard

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: Rapid
acceleration, abrupt cornering,
and hard braking increase fuel
consumption.
Aerodynamic drag has a big ef f ect
on f uel economy 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 (0 kms
per liter).
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.

Fill the f uel tank until the nozzle automatically clicks of f .
Reset trip counter to zero.
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
one. A warmed-up engine is more
f uel ef f icient than a cold one.
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.

modif ications or add any accessories,
be sure to read the f ollowing
inf ormation.
Your dealer has Honda accessories
that allow you to personalize your
vehicle, or improve its perf ormance.
These accessories have been
designed and approved f or your
vehicle, and are covered by warranty.
Although non-Honda accessories
may f it on your vehicle, they may not
meet f actory specif ications, and
could adversely af f ect your vehicle’s
handling, stability, and reliability.When properly installed, cellular
phones, alarms, two-way radios, and
low-powered audio systems should
not interf ere with your vehicle’s
computer controlled systems, such
as your airbags, anti-lock brakes, and
tire pressure monitoring system (if
equipped).Bef ore installing any accessory:
Make sure the accessory does not
obscure any lights, or interf ere
with proper vehicle operation or
perf ormance.
Be sure electronic accessories do
not overload electrical circuits
(see page ) or interf ere with
the proper operation of your
vehicle.
Bef ore installing any electronic
accessory, have the installer
contact your dealer for assistance.
If possible, have your dealer
inspect the f inal installation.
Do not install accessories on the
side pillars or across the rear
windows. Accessories installed in
theseareasmayinterferewith

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.
Some examples are:
Lowering your 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.
Raising your vehicle with a
non-Honda suspension kit can
af f ect the handling, stability, and
reliability. Larger or smaller wheels and tires
can interf ere with the operation of
your vehicle’s anti-lock brakes and
other systems.
Modif ying your steering wheel or
any other part of your vehicle’s
safety features can make the
systems inef f ective.
If you plan to modif y your vehicle,
consult your dealer. 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) .

The maximum load f or your vehicle
is 850 lbs (385 kg) f or U.S. models
and 395 kg for Canadian models.
Label Example See Tire And Loading Inf ormation
label attached to the driver’s
doorjamb.
This f igure includes the total weight
of all occupants, cargo, and
accessories, and the tongue load if
you are towing a trailer.
Determine the combined weight
of the driver and passengers that
will be riding in your vehicle.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.)
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.
Subtract the combined weight of
the driver and passengers f rom
XXX kg or XXX 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 your vehicle will be towing a
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.
