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

The following factors can lower your

vehicle’s 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

information display (see

on page

).

For example:

An under-inflated tire increases

‘‘rolling resistance,’’ which reduces

fuel economy.

It puts a heavier

load on the engine, increasing 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.

Rapid

acceleration, abrupt cornering,

and hard braking increase fuel

consumption.

Aerodynamic drag has a big effect

on fuel 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 fuel economy by up

shifting as early as possible.

Idling

results in 0 miles per gallon.
