The following factors can lower your
vehicle's fuel economy:
Aggressive driving (hard

Improving Fuel Economy
Vehicle Maintenance
A 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 multi-
information display (see
Owner's
Maintenance Checks on page
For example:
Use the recommended viscosity
motor oil, displaying the API
Certification Seal (see page
458 ).
Maintain proper tire inflation
An underinflated tire increases
−
''rolling resistance,'' which reduces
fuel economy.
Avoid carrying excess weight in
your vehicle
load on the engine, increasing fuel
consumption.
Keep your vehicle clean
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
acceleration, abrupt cornering,
and hard braking increase fuel
consumption.

Fuel Economy
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.
Avoid excessive idling −
results in 0 miles per gallon.
