The following factors can lower your
vehicle’s fuel economy:
Idling
results in 0 miles per gallon (0 kms
per liter).
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.
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 fuel
economy.
It puts a heavier
load on the engine, increasing fuel
consumption.
An underinflated tire increases
‘‘rolling resistance,’’ which reduces
fuel economy.
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
on page
).
For example:
Improperly inflated tires
Driving with a heavy load or the
air conditioner running
Cold engine operation (engines
are more efficient when warmed
up)
Excessive idling, accelerating and
braking in stop-and-go traffic
Aggressive driving (hard
acceleration and braking)
