GETTING TO KNOW YOUR VEHICLE
HIGH VOLTAGE BATTERY
Your vehicle is equipped with a Lithium-ion high
voltage battery that is used to power the electric
powertrain systems and the 12 Volt vehicle
electrical system.
The high voltage battery is located under the
rear seat.
Lithium-ion batteries provide the following
benefits:

Lithium-ion batteries are much lighter than
other types of rechargeable batteries of the
same size.

Lithium-ion batteries hold their charge; they
only lose approximately three percent of their
charge per month.

Lithium-ion batteries have no memory, which
means that you do not have to completely
discharge them before recharging, as with
some other batteries.

Lithium-ion batteries can be recharged and
discharged thousands of times.
High Voltage Battery Service Disconnect
The high voltage battery service disconnect is
located under the access panel, under the left
side rear seat.
If your vehicle requires high voltage battery
service, see an authorized dealer.
Disposal of the High Voltage Battery
Your vehicle’s high voltage battery is designed
to last the life of your vehicle. See an authorized
dealer for information on the disposal of the
battery if it should require replacement.
General Information
The vehicle is also equipped with a Battery
Management system that is designed to:

Ensure safe operation

Maximize driving range

Maximize the life expectancy of the high
voltage battery
NOTE:
During vehicle start up and shut down, a
clicking noise may be heard from within the
vehicle. When the vehicle is preparing to start,
the high voltage battery contactors inside the
battery are closed to make the stored electricity
inside available for vehicle use. After the vehicle
is shut down, the contactors open to electrically
isolate the battery from other vehicle systems.
The clicking noise heard is the sound of these
contactors as they open and close during
normal operation.

ONDITIONING
In extreme temperatures, high or low, the high
voltage battery may need to be conditioned,
and therefore may require the vehicle to be
plugged in.
If the ambient temperature is 5°F (-15°C) or
below at vehicle shut down, the instrument
cluster will display the message “Plug In Vehicle
To Condition Battery”.
