● Keep your engine tuned up. ● Follow the recommended periodic maintenance schedule. ● Keep the tires inflated to the correct pressure. Low tire pressure increases tire wear and wastes fuel. ● Keep the front wheels in correct alignment. Improper alignment increases tire wear and lowers fuel economy. ● Air conditioner operation lowers fuel economy. Use the air conditioner only when necessary. ● When cruising at highway speeds, it is more economical to use the air conditioner and leave the windows closed to reduce drag. ● Use 4H or 4L position only when necessary.
