INCREASING FUEL ECONOMY SD0001 ● Accelerate slowly and smoothly. Maintain cruising speeds with a constant accelerator position. ● Drive at moderate speeds on the highway. Driving at high speeds 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. 5-14 Starting and driving
