•You may want to turn off the speed control in hilly terrain if
unnecessary shifting between the top gears occurs. Unnecessary
shifting of this type could result in reduced fuel economy.
•Warming up a vehicle on cold mornings is not required and may
reduce fuel economy.
•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 toMaintenance product
specifications and capacitiesin this chapter.
•Perform all regularly scheduled maintenance items. Follow the
recommended maintenance schedule and owner maintenance checks
found inscheduled 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.

For maximum vehicle performance, keep the following information in
mind when adding accessories or equipment to your vehicle:
•When adding accessories, equipment, passengers and luggage to your
vehicle, do not exceed the total weight capacity of the vehicle or of
the front or rear axle (GVWR or GAWR as indicated on the Safety
Compliance Certification label). Consult your authorized dealer for
specific weight information.
•The Federal Communications Commission (FCC) and Canadian Radio
Telecommunications Commission (CRTC) regulate the use of mobile
communications systems — such as two-way radios, telephones and
theft alarms - that are equipped with radio transmitters. Any such
equipment installed in your vehicle should comply with FCC or CRTC
regulations and should be installed only by a qualified service
technician.
•Mobile communications systems may harm the operation of your
vehicle, particularly if they are not properly designed for automotive
use.
•To avoid interference with other vehicle functions, such as anti-lock
braking systems, amateur radio users who install radios and antennas
onto their vehicle should not locate the Amateur Radio Antennas in
the area of the driver’s side hood.
•Electrical or electronic accessories or components that are added to
the vehicle by the authorized dealer or the owner may adversely affect
battery performance and durability.
