INCREASING FUEL ECONOMY ● Accelerate slowly and smoothly. Maintain cruising speeds with a constant accelerator position. ● Drive at moderate speeds on the highway. Driving at high speed lowers fuel economy. ● Avoid unnecessary stopping and braking. Maintain a safe distance behind other vehicles. ● Use a proper gear range which suits road conditions. On level roads, shift into high gear as soon as possible. ● Avoid unnecessary engine idling. ● 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 lowers fuel economy. ● Keep the 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 the recommended viscosity engine oil. See "Engine oil and oil filter recommendation" in "Technical and consumer information" later in this manual. Starting and driving 5-15
