Driving for Better Fuel

Economy

Driving habits can affect fuel
mileage. Here are some driving tips
to get the best fuel economy
possible:
Set the climate controls to the
desired temperature after the
engine is started, or turn them
off when not required.
Avoid fast starts and accelerate
smoothly.
Brake gradually and avoid
abrupt stops.
Avoid idling the engine for long
periods of time.
When road and weather
conditions are appropriate, use
cruise control.
Always follow posted speed
limits or drive more slowly when
conditions require.
Keep vehicle tires properly
inflated.
Combine several trips into a
single trip.
Replace the vehicle's tires with
the same TPC Spec number
molded into the tire's sidewall
near the size.
Follow recommended scheduled
maintenance.
