Maintenance and Specifications • Resting your foot on the brake pedal while driving may reduce fuel economy. • Combine errands and minimize stop-and-go driving. Maintenance • Keep tires properly inflated and use only recommended size. • Operating a vehicle with the wheels out of alignment will reduce fuel economy. • Use recommended engine oil. Refer to Lubricant specifications in this chapter. • Perform all regularly scheduled maintenance items. Follow the recommended maintenance schedule and owner maintenance checks found in scheduled maintenance information. Conditions • Heavily loading a vehicle or towing a trailer may reduce fuel economy at any speed. • Carrying unnecessary weight may reduce fuel economy (as much as 1 mpg [0.4 km/L] is lost for every 400 lb [180 kg] of weight carried). • Adding certain accessories to your vehicle (for example bug deflectors, rollbars/light bars, running boards, ski/luggage racks) may reduce fuel economy. • Using fuel blended with alcohol may lower fuel economy. • Fuel economy may decrease with lower temperatures during the first 8-10 miles (12-16 km) of driving. • Driving on flat terrain offers improved fuel economy as compared to driving on hilly terrain. • Transmissions give their best fuel economy when operated in the top cruise gear and with steady pressure on the gas pedal. • Four-wheel-drive operation (if equipped) is less fuel efficient than two-wheel-drive operation. • Close windows for high speed driving. EPA window sticker The characteristics of the four wheel drive vehicle, like those of many, similar competitive products, fit within categories where the fuel economy labeling regulations do not apply. Therefore, the following information applies only to the two wheel drive vehicle. 377 2005 Navigator (nav) Owners Guide (post-2002-fmt) USA_English (fus)
