5. Follow one of the simple calculations in order to determine fuel economy:
Calculation 1: Divide total miles traveled by total gallons used.
Calculation 2: Multiply liters used by 100, then divide by total
kilometers traveled.
Keep a record for at least one month and record the type of driving (city or
highway). This will provide an accurate estimate of the vehicle’s fuel
economy under current driving conditions. Additionally, keeping records
during summer and winter will show how temperature impacts fuel economy.
In general, very hot or very cold temperatures give lower fuel economy.
Driving style — good driving and fuel economy habits
Since it is able to operate in electric mode and to collect braking energy,
your hybrid vehicle may get better fuel economy in city driving than on
the highway. This is contrary to conventional vehicles. However, many of
the same actions that improve fuel economy in a conventional vehicle
will also improve fuel economy in this vehicle.
Give consideration to the lists that follow and you may be able to
improve your fuel economy.
Habits
• Avoid aggressive driving. Quick acceleration and deceleration decrease
fuel economy.
• Drive at a smooth, constant speed. Excessive variation in pedal input
causes more operating mode changes and reduces efficiency.
• Drive at reasonable speeds. Traveling at 60 mph [96 km/h] uses
approximately 20% less fuel than traveling at 70 mph [112 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, or choosing
a higher temperature setting can help reduce energy usage.
• 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.
