Fuel Economy Factors
The 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 tiresImproving Fuel Economy
Vehicle 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 (see
Owner's
Maintenance Checks on page250).
For example:●Use the recommended viscosity
motor oil, displaying the API
Certification Seal (see page
253).●Maintain proper tire inflation －
An under-inflated 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 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.●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.
