Fuel Economy FactorsThe following factors can lower your
vehicle's fuel economy:●Aggressive driving (hard
acceleration and braking)●Excessive idling, accelerating and
braking in stop-and-go traffic●Cold engine operation (engines are
more efficient when warmed up)●Driving with a heavy load or the air
conditioner running●Improperly inflated tires
Improving Fuel EconomyVehicle MaintenanceA properly maintained vehicle
maximizes fuel economy. Poor
maintenance can significantly reduce
fuel economy. Always maintain your
vehicle according to the maintenance
messages displayed on the
information display (seeOwner's
Maintenance Checks on page417).
For example:●Use the required engine oil (see
page 420).●Maintain proper tire inflation －
An underinflated tire increases
‘‘ rolling resistance, ’’which reduces
fuel economy.●Avoid carrying excess weight in
your vehicle －It puts a heavier
load on the engine, increasing fuel
consumption.
●Keep your vehicle clean －In
particular, a build-up of snow or
mud on your vehicle's underside
adds weight and rolling resistance.
Frequent cleaning helps your fuel
economy.

Drive Efficiently●Drive moderately－Rapid
acceleration, abrupt cornering, and
hard braking increase fuel
consumption.●Observe the speed limit －
Aerodynamic drag has a big effect
on fuel 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.
●Always drive in the highest gear
possible －If your vehicle has a
manual transmission, you can
boost your fuel economy by up
shifting as early as possible.●Avoid excessive idling －Idling
results in 0 miles per gallon (0 kms
per liter).
●Minimize the use of the air
conditioning system －The A/C
puts an extra load on the engine
which makes it use more fuel. Use
the fresh-air ventilation when
possible.●Plan and combine trips －
Combine several short trips into
one. A warmed-up engine is more
fuel efficient than a cold one.
