IN BRIEF 33
Climate Setting
Using the heat and air conditioning
systems decreases the energy available
for electric driving.
Optimal energy efficiency is achieved
with the heat, air conditioning, and
fan turned off.
Less energy is used at low fan speeds.
Use the heated seat feature and the
heated steering wheel instead of
climate settings. Heating the seat and
steering wheel uses less energy than
heating the vehicle interior.
Use remote start to heat or cool the
interior when the vehicle is plugged in
to maximize the electric range by
utilizing electricity from the electrical
outlet.
In hot weather, avoid parking in direct
sunlight or use sunshades inside the
vehicle.
Turn off the front and rear window
defog/defrost when they are no longer
needed.
Avoid driving with the windows open
at highway speeds.
Vehicle Charging/Maintenance
Charging
Keep the vehicle plugged in, even
when fully charged, to keep the
battery temperature ready for the next
drive. This is important when outside
temperatures are extremely hot
or cold.
Maintenance
Always keep the tires properly inflated
and the vehicle properly aligned.
The weight of excess cargo in the
vehicle affects efficiency and range.
Avoid carrying more than is needed.
If fuel is not regularly used, consider
keeping the fuel tank only one-third
full. Excess fuel weight impacts
efficiency and range.
For fuel recommendations, seeFuel
0 286.
Avoid unnecessary use of electrical
accessories. Power used for functions
other than propelling the vehicle will
reduce EV range. Using a rooftop carrier will reduce
efficiency due to additional weight
and drag.
