Owner's Manual

• Drive at reasonable speeds. Traveling at 60 mph (96 km/h) uses
approximately 20% less fuel than traveling at 70 mph (113 km/h).
• Minimize A/C and defroster usage. Your vehicle is equipped with an
electric A/C system, which can provide cooling for passenger comfort
or defrost without running the engine. However, the A/C system uses
battery energy when the engine is off, which reduces fuel economy.
Using Auto mode, minimizing use of defrost and Max A/C, and
choosing a higher temperature setting when cooling can help reduce
energy usage. See the Climate Control chapter for more information.
• Minimize temperature extremes when the vehicle is parked, for
example by storing in a garage to avoid extreme cold in winter and
extreme sun loads in summer. The high voltage battery operates more
efficiently in moderate temperatures, and less energy will be spent
returning the passenger compartment to a comfortable temperature.
• Combine errands. Your vehicle is more fuel efficient when the engine
is warm. Driving to your farthest destination first will warm the engine
more quickly and may improve fuel economy for the rest of the trip.
Maintenance
• Keep tires properly inflated and use only recommended size.
• Keep wheels properly aligned.
• Use recommended engine oil. Refer to Maintenance product
specifications and capacities 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 (approximately
1 mpg [0.4 km/L] is lost for every 300 lb [136 kg] of weight carried).
• Adding certain accessories to your vehicle (for example; bug
deflectors, rollbars/light bars, running boards, ski/luggage racks, flags)
may reduce fuel economy.
• Using fuel blended with alcohol may lower fuel economy.
• Driving on flat terrain offers improved fuel economy as compared to
driving on mountainous terrain.
EMISSION CONTROL SYSTEM
Your vehicle is equipped with various emission control components and a
catalytic converter which will enable your vehicle to comply with
