The f ollowing f actors can lower your
vehicle’s f uel economy:
Idling
results in 0 miles per gallon (0 kms
per liter). Aerodynamic drag has a big ef f ect
on f uel 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. Rapid
acceleration, abrupt cornering,
and hard braking increase fuel
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. It puts a heavier
load on the engine, increasing f uel
consumption. An underinf lated tire increases
‘‘rolling resistance,’’ which reduces
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:
Improperly inf lated tires Driving with a heavy load or the
air conditioner running Cold engine operation (engines
aremoreefficientwhenwarmed
up) Excessive idling, accelerating and
braking in stop-and-go traf f ic Aggressive driving (hard
acceleration and braking)
