Reducing Fuel Consumption
The following tips will help improve fuel economy.
Avoid unnecessary idling: If you must wait at a stop for more than one minute, switch off the engine and restart it later. When warming up a cold engine, let it idle until the engine temperature gauge reaches the "C" position. The engine will then be warm enough to drive off.
Avoid rapid starts
Pulling away quickly from traffic lights or a "stop" sign unnecessarily wastes fuel and shortens engine life. Accelerate gently.
Avoid unnecessary stops
Avoid unnecessary slowing and stopping.
Try to maintain a slow, steady speed whenever possible. Slowing down and then accelerating again wastes additional fuel.
Maintain a steady driving speed
Maintain a steady speed to the extent that road conditions allow.
Keep the air filter clean
A dirty air filter causes the fuel system to supply too much fuel relative to air. The result is wasted fuel due to incomplete combustion.
Reduce vehicle weight
The heavier the load, the higher the fuel consumption. Remove all unnecessary loads and items being carried.
Maintain tire pressure
Tire pressure that is too low may increase fuel consumption due to higher rolling resistance. Maintain the pressure specified on the label on the driver's side door or door pillar.
