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. Four-wheel drive operation lowers fuel economy. SD0001 Accelerate slowly and smoothly. Maintain cruising speeds with a constant accelerator position. Drive at moderate speeds on the highway.
