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
inf ormation display (see
on page ).
For example: Rapid
acceleration, abrupt cornering,
and hard braking increase fuel
consumption.
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.
If your vehicle has a
manual transmission, you can
boost your f uel economy by up
shif ting as early as possible.
Idling
results in 0 miles per gallon.
‘‘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.
