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 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. Four-wheel drive operation lowers fuel economy. (4WD) USING FOUR WHEEL DRIVE TRANSFER CASE SHIFTING PROCEDURES The part time 4WD system provides 3 positions (2WD, 4H and 4LO), so you can select the desired drive mode according to the driving conditions. 2WD or 4WD shift procedure: CAUTION ● Do not drive the vehicle in the 4H or 4LO position on dry hard surface roads. Driving on dry, hard surfaces in 4H or 4LO may cause unnecessary noise, tire wear and increased fuel consumption. If the 4WD warning light turns on when you are driving on dry hard surface roads: - in the 4H position, shift the 4WD shift switch to 2WD. - in the 4LO position for automatic transmission vehicles, stop the vehicle and shift the transmission selector to the N position with the brake pedal depressed and shift the 4WD shift switch to 2WD. - in the 4LO position for manual transmission vehicles, stop the vehicle and shift the transmission shift lever to the N position with the clutch pedal depressed and shift the 4WD shift switch to 2WD. ● If the warning light is still on after the above operation, have your vehicle checked by a NISSAN dealer as soon as possible. 5-20 Starting and driving
