Fuel Economy
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 tires
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
Maintenance Checks
For example:
254
Use the recommended viscosity
motor oil, displaying the API
Certification Seal (see page
313
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.

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.
