Remove ice from the area
and repeat attempting to
open the charge port door.
4. Unlatch the DC chargingdust cover and lower it fully.
5. Plug in the DC charge cord into the vehicle charge port.
Make sure that the DC
vehicle plug is fully
connected to the DC charge
port. If it is not properly
connected, the vehicle may
not be charged. Check the
Driver Information Center
(DIC) to make sure the
vehicle plug is connected
properly. 6. Follow the steps listed on
the charging station to start
charging.
7. When charging is active, the DC vehicle plug is locked to
the DC charge port and
cannot be disconnected.
8. Verify that the charge status light turns on and an
audible chirp occurs. See
Charging Status Feedback
0289.
Caution
Do not attempt to
disconnect the DC vehicle
plug while charging is active.
This action may damage the
vehicle or charging station
hardware.
To Stop DC Charging —
Automatic
When the vehicle no longer
needs power from the
charging station, it stops
charging and the DC vehicle
plug unlocks from the DC
charge port. Energy can still be consumed
from the charging station
when the vehicle displays and
indicators show that the
battery is fully charged. This is
to ensure the battery is in
optimal temperature operating
range to maximize vehicle
range. See Charging
0123.
To End DC Charging 1. Wait until the charging process has fully stopped,
the DC vehicle plug is
unlocked, and the charging
status indicator is solid
green or off.
If the vehicle plug does not
unlock from the vehicle
charge port after a charge,
contact Roadside Service.
See Roadside Service 0388.
2. Unplug the DC vehicle plug from the DC charge port on
the vehicle and close the
dust cover.
3. Close the charge port door by pressing firmly in the

Add-Ons
Add-On Electrical
Equipment
{Warning
The Data Link Connector
(DLC) is used for vehicle
service and Emission
Inspection/Maintenance
testing. See Service Vehicle
Soon Light0115. A device
connected to the DLC —
such as an aftermarket fleet
or driver-behavior tracking
device —may interfere with
vehicle systems. This could
affect vehicle operation and
cause a crash. Such devices
may also access information
stored in the vehicle’s
systems.
Caution
Some electrical equipment
can damage the vehicle or
cause components to not
work and would not be
covered by the vehicle
warranty. Always check with
your dealer before adding
electrical equipment.
Add-on equipment can drain
the vehicle's 12-volt battery,
even if the vehicle is not
operating.
When adding electrical
equipment, it should only be
connected using the
accessory power outlets. The
maximum power that can be
supplied by one accessory
power outlet or spread across
all three is 200 watts or
15 amps. Exceeding 200 watts
or 15 amps may cause erratic
vehicle operation. The vehicle has an airbag
system. Before attempting to
add anything electrical to the
vehicle, see Servicing the
Airbag-Equipped Vehicle
071
and Adding Equipment to the
Airbag-Equipped Vehicle 071.

Doing Your Own
Service Work
{Warning
Never try to do your own
service on high voltage
battery components. You
can be injured and the
vehicle can be damaged if
you try to do your own
service work. Service and
repair of these high voltage
battery components should
only be performed by a
trained dealer technician
with the proper knowledge
and tools.
(Continued)
Warning (Continued)
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. Do not probe,
tamper with, cut, or modify
high voltage cable or wiring.
{Warning
Unexpected wheel motion
and/or direction when one
or more wheels are off the
ground for service work may
result in injury. The
vehicle may:(Continued)

2. Hood Latch.
3. Brake Fluid Reservoir. See Brake Fluid 0316.
Cooling System
It is not necessary to regularly
check coolant unless a leak is
suspected or an unusual noise
is heard. A coolant loss could
indicate a problem. Have it
inspected and repaired by
your dealer.
During vehicle operation and
also during charging, the high
voltage battery cells in the
vehicle are kept within a
normal operating temperature
range. If the temperature rises
above this temperature, the
battery cooling system turns
on the air conditioning
compressor and cools the
coolant until the correct
temperature is reached. If the
temperature falls below this
temperature, a high voltage heater, located outside the
battery on a cradle, heats the
coolant until the correct
temperature is reached.
The cooling system allows the
vehicle to maintain the correct
working temperature.Checking Coolant
The coolant needs to be
replaced at the appropriate
interval. See Maintenance
Schedule
0376.
The coolant reservoir is in the
underhood compartment. See
Underhood Compartment
Overview 0312.
To access the coolant
reservoir under the hood, the
right side access cover needs
to be removed. 1. Park on a level surface and turn the vehicle off.
2. Open the hood. See Hood 0310.
3. The coolant reservoir is
under a cover and side
extension/shield in the
underhood compartment.
Unclip the right side of the
shield and remove the right
side access cover.

Battery - North
America
This vehicle has a high voltage
battery and a standard 12-volt
battery.
See your dealer if either the
12-volt or high voltage battery
needs service.
12–Volt Battery
The original equipment battery
is maintenance free. Do not
remove the cap and do not
add fluid.
Refer to the replacement
number shown on the original
battery label when a new
12-volt battery is needed. The
vehicle has an Absorbent
Glass Mat (AGM) 12-volt
battery. Installation of a
standard 12-volt battery will
result in reduced 12-volt
battery life.
Some 12-volt chargers have an
AGM battery setting. This
setting limits the charge
voltage to 14.8 volts and helpsextend the battery life.
If available, use the AGM
setting when charging the
battery.
{Warning
WARNING:
Battery posts,
terminals and related
accessories can expose you
to chemicals including lead
and lead compounds, which
are known to the State of
California to cause cancer
and birth defects or other
reproductive harm. Wash
hands after handling. For
more information go to
www.P65Warnings.ca.gov.
See California Proposition
65 Warning 01.
High Voltage Battery
Only a trained service
technician should inspect, test,
or replace the high voltage
battery. The dealer has
information on how to recycle
the high voltage battery. There is also information
available at https://
www.recyclemybattery.com.
{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.
