In Brief 21
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(Continued)
Warning (Continued)
structure or anything that can
burn. Ventilate the vehicle by
opening a window or a door.
Contact Customer Assistance as
soon as possible to determine
whether an inspection is needed.

0 343.
See Battery - North America 0253
for important safety information.
If an airbag has inflated, see What
Will You See after an Airbag
Inflates? 070.
Only a trained service technician
with the proper knowledge and tools
should inspect, test, or replace the
high voltage battery. See your
dealer if the high voltage battery or
12-volt battery needs service.
See Battery - North America 0253.
Charging
This section explains the process
for charging the high voltage battery.
Do not allow the vehicle to remain in
temperature extremes for long
periods without being driven or
plugged in. Plug the vehicle in when
temperatures are below 0 °C (32 °F)
and above 32 °C (90 °F) to
maximize high voltage battery life.
When using a 120-volt AC electrical
outlet, it will take approximately
13 hours to charge the vehicle with
the 12 amp AC current setting or
19 hours using the default 8 amp
AC current setting. When using a
240-volt charging station, it will take
approximately 4.5 hours to charge
the vehicle. Charge times will vary
with outside temperature. There are
three ways to program how the
vehicle is charged. See
Programmable Charging 0123.
The charging system may run fans
and pumps that result in sounds
from the vehicle while it is turned
off. Additional unexpected clicking

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
0 228.
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.

arm if the doors are locked with
the key.
If the driver door is opened without
first unlocking with the RKE
transmitter, the horn will chirp and
the lights will flash to indicate
pre-alarm. If the vehicle is not
started, or the door is not unlocked
by pressing
Kon the RKE
transmitter during the 10-second
pre-alarm, the alarm will be
activated.
The alarm will also be activated if
there is an attempt to remove the
charge cord, or if a passenger door,
the hatch, or the hood is opened,
without first disarming the system.
When the alarm is activated, the
turn signals flash and the horn
sounds for about 30 seconds. The
alarm system will then re-arm to
monitor for the next unauthorized
event. The charge cord theft alert feature
may be disabled through the vehicle
personalization. See

How to Detect a Tamper
Condition
IfKis pressed on the transmitter
and the horn chirps and the lights
flash three times, a previous alarm
occurred while the system was
armed.
If the alarm has been activated, a
message will appear on the Driver
Information Center (DIC).
Immobilizer
See Radio Frequency Statement
0 351.
Immobilizer Operation
This vehicle has a passive
theft-deterrent system. The system
does not have to be manually
armed or disarmed.
The vehicle is automatically
immobilized when the vehicle is
turned off.
The system is automatically
disarmed when the vehicle is
started with a valid RKE transmitter in the vehicle. The RKE transmitter
uses electronic coding that matches
an immobilizer control unit in the
vehicle and automatically disarms
the system. Only a correct
transmitter can be used to turn the
vehicle on.
The security light comes on if there
is a problem with arming or
disarming the theft-deterrent
system.
This light may come on briefly when
the vehicle is turned on. There is a
problem if the engine does not start
and this light stays on.
Turn the ignition off and try again.
If the engine still does not start, and
the RKE transmitter appears
undamaged, try the other RKE
transmitter for the vehicle, or place
the RKE transmitter in thetransmitter pocket. See
Remote
Keyless Entry (RKE) System
Operation 032. It may be necessary
to check the fuse. See Electrical
System Overload 0261. If the
vehicle does start, the first
transmitter is bad. If the vehicle still
does not start, the vehicle needs
service. See your dealer.
Do not leave the key or device that
disarms or deactivates the vehicle
theft-deterrent system in the vehicle.
