• 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 fuel economy estimates

Every new vehicle should have a window sticker containing EPA fuel
economy estimates. Contact your authorized dealer if the window sticker
is not supplied with your vehicle. The EPA fuel economy estimates
should be your guide for the fuel economy comparisons with other
vehicles. Your fuel economy may vary depending upon the method of
operation and conditions.

EMISSION CONTROL SYSTEM

Your vehicle is equipped with various emission control components and a
catalytic converter which will enable your vehicle to comply with
applicable exhaust emission standards. To make sure that the catalytic
converter and other emission control components continue to work
properly:
• Use only the specified fuel listed.
• Avoid running out of fuel.
• Do not turn off the ignition while your vehicle is moving, especially at

high speeds.

• Have the items listed in scheduled maintenance information

performed according to the specified schedule.

The scheduled maintenance items listed in scheduled maintenance
information
are essential to the life and performance of your vehicle
and to its emissions system.
