High Voltage Safety
Information
{Warning
Exposure to high voltage can cause
shock, burns, and even death. The
high voltage components in the
vehicle can only be serviced by
technicians with special training.
High voltage components are
identified by labels. Do not remove,
open, take apart, or modify these
components. High voltage cable or
wiring has orange covering or
labels. Do not probe, tamper with,
cut, or modify high voltage cable or
wiring.
This vehicle has a high voltage battery
and a standard 12-volt battery.
If the vehicle is in a crash, the sensing
system may shut down the high
voltage system. When this occurs, the
high voltage battery is disconnected and the vehicle will not start. The
SERVICE VEHICLE SOON message in
the Driver Information Center (DIC)
will be displayed. Before the vehicle
can be operated again, it must be
serviced at your dealer.{Warning
Damage to the high voltage battery
or high voltage system can create a
risk of electric shock, overheating,
or fire.
If the vehicle is damaged from a
moderate to severe crash, flood,
fire, or other event, the vehicle
should be inspected as soon as
possible. Until the vehicle has been
inspected, store it outside at least
15 m (50 ft) from any structure or
anything that can burn. Ventilate
the vehicle by opening a window or
a door.
Contact your dealer as soon as
possible to determine whether an
inspection is needed.

Charge Cord
Important Information About
Portable Electric Vehicle Charging
.Charging an electric vehicle can
stress a building’s electrical
system more than a typical
household appliance. .
Before you plug in to any electrical
outlet, have a qualified electrician
inspect and verify the electrical
system (electrical outlet, wiring,
junctions, and protection devices)
for heavy-duty service at a 12 amp
continuous load.
. Electrical outlets may wear out
with normal usage or be damaged
over time, making them unsuitable
for electric vehicle charging.
. Check the electrical outlet/plug
while charging and discontinue
use if the electrical outlet/plug is
hot, then have the electrical outlet
serviced by a qualified electrician.
. When outdoors, plug into an
electrical outlet that is
weatherproof.
. Mount the charging cord to reduce
strain on the electrical outlet/plug.

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.

{Warning
Leaving children in a vehicle with a
Remote Keyless Entry (RKE)
transmitter is dangerous and
children or others could be
seriously injured or killed. They
could operate the power windows
or other controls or make the
vehicle move. The windows will
function with the RKE transmitter
in the vehicle, and children or
others could be caught in the path
of a closing window. Do not leave
children in a vehicle with an RKE
transmitter.

The RCM may not work properly or
display a clear image if:
.There is glare from the sun or
headlamps. This may obstruct
objects from view.
. Dirt, snow, or other debris blocks
the camera lens. Clean the lens
with a soft damp cloth.

{Warning
Never leave a child, a helpless adult,
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.
The vehicle aerodynamics are
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.
