• 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

12–16 km (8–10 miles) 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

Every new vehicle should have the EPA window sticker. Contact your

dealer if the window sticker is not supplied with your vehicle. The EPA

window sticker should be your guide for the fuel economy comparisons

with other vehicles.

It is important to note the box in the lower left corner of the window

sticker. These numbers represent the Range of L/100 km (MPG)

expected on the vehicle under optimum conditions. 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 your scheduled maintenance guide performed

according to the specified schedule.

The scheduled maintenance items listed in the scheduled maintenance

guide are essential to the life and performance of your vehicle and to its

emissions system.
