Maximizing Fuel Economy
Your driving behavior is a big contributor
to your vehicle’s fuel economy.
Modifying your driving habits will
improve your fuel mileage. Here are
several fuel-saving tips:
• Combine short trips to minimize cold
engine starts, which reduce fuel
economy.
• Avoid quick starts and stops.
Accelerate moderately and drive at a
steady speed.
• Anticipate traffic flow and brake mod-
erately or coast.
• Use the air conditioning and defrost
modes only when necessary.
• Minimize electrical accessory opera-
tion by turning off items such as the
rear defogger and heated seats when
they are not needed.
• Use the remote start feature sparing-
ly. This feature turns the engine on,
consuming fuel at idle.
• Do not warm up the engine by idling.
Even on the coldest days, driving will
help the engine warm up faster.
• Selecting the AUTO feature on 4WD
models will be less economical than
2WD.
• Unload unnecessary cargo to reduce
the amount of weight in the vehicle.
• Regularly check and maintain proper
tire pressure.
• Maintain your vehicle. Regular main-
tenance will keep your vehicle run-
ning cleaner and more efficiently.
