Conditions

• Heavily loading a vehicle may reduce fuel economy at any speed.
• Carrying unnecessary weight may reduce fuel economy (approximately 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.
• Close windows for high speed driving.
