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
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.

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.
Avoid excessive idling

results in 0 miles per gallon (0 kms
