Aggressive driving (hard

Excessive idling, accelerating and
braking in stop-and-go traf f ic
Cold engine operation (engines

Driving with a heavy load or the
air conditioner running
Improperly inf lated tires
An under-inf lated tire increases
‘‘rolling resistance,’’ which reduces
f uel economy.
It puts a heavier
load on the engine, increasing f uel
consumption. In
particular, a build-up of snow or
mud on your vehicle’s underside
adds weight and rolling resistance.
Frequent cleaning helps your f uel
economy.
The f ollowing f actors can lower your
vehicle’s f uel economy:
A properly maintained vehicle
maximizes f uel economy. Poor
maintenance can signif icantly reduce
f uel economy. Always maintain your
vehicle according to the maintenance
messages displayed on the multi-
inf ormation display (see
on page ).
For example: Idling
results in 0 miles per gallon. If your vehicle has a
manual transmission, you can
boost your f uel economy by up
shif ting as early as possible.
Aerodynamic drag has a big ef f ect
on f uel 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.
Rapid
acceleration, abrupt cornering,
and hard braking increase fuel
consumption.
