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.

restrict the use of remote starters. For
example, some laws may require a
person using remote start to have the
vehicle in view. Check local
regulations for any requirements.
If your vehicle is low on fuel, do not
use the remote start feature. The
vehicle may run out of fuel.

or a pet alone in a vehicle,
especially with the windows closed
in warm or hot weather. They can
be overcome by the extreme heat
and suffer permanent injuries or
even death from heat stroke.

designed to improve fuel economy
performance. This may result in a
pulsing sound when either rear window is down and the front
windows are up. To reduce the sound,
open either a front window or the
sunroof, if equipped.

are installed and adjusted properly.
If your vehicle has rear head
restraints that fold down, always
return them to the full upright
position whenever an occupant is
seated in the seat.
Adjust the head restraint so that the
top of the restraint is at the same
height as the top of the occupant's
head. This position reduces the
chance of a neck injury in a crash.

Reclining Seatbacks
Platinum Seat Shown, Base andUplevel Seats Similar
To adjust:
. Tilt the top of the control
rearward to recline.
. Tilt the top of the control forward
to raise the seatback.
{Warning
Sitting in a reclined position when
the vehicle is in motion can be
dangerous. Even when buckled up,
the seat belts cannot do their job.
The shoulder belt will not be
against your body. Instead, it will be
in front of you. In a crash, you
could go into it, receiving neck or
other injuries.
The lap belt could go up over your
abdomen. The belt forces would be
there, not at your pelvic bones. This
could cause serious internal
injuries.
For proper protection when the
vehicle is in motion, have the
seatback upright. Then sit well back
in the seat and wear the seat belt
properly.
Do not have a seatback reclined if the
vehicle is moving.
