Air Conditioning Regular
Operation
To ensure continuous efficient
performance, operate the air
conditioning for a few minutes once
a month. The air conditioning will
not operate if the outside
temperature is too low.
Caution
Damage caused by improper
refrigerant usage could lead to
costly repairs and may not be
covered by the vehicle warranty.
Refrigerant systems should only
be serviced by qualified
personnel. Always use the correct
refrigerant.
{Warning
Performing service work to the
climate control system could
cause personal injury or damage
to the vehicle. Climate control
systems are serviced by qualified
personnel only.
Service
All vehicles have a label underhood
that identifies the refrigerant used in
the vehicle. The refrigerant system
should only be serviced by trained
and certified technicians. The air
conditioning evaporator should
never be repaired or replaced by
one from a salvage vehicle.
It should only be replaced by a new
evaporator to ensure proper and
safe operation.During service, all refrigerants
should be reclaimed with proper
equipment. Venting refrigerants
directly to the atmosphere is harmful
to the environment and may also
create unsafe conditions based on
inhalation, combustion, frostbite,
or other health-based concerns.
The air conditioning system requires
periodic maintenance. See
Maintenance Schedule
0301.

Driving Information
Driving for Better Energy
Efficiency
Use the following tips to help
maximize energy efficiency and
range.
In colder temperatures, while these
efficiency tips will help, the electric
vehicle driving range will be lower
due to higher energy usage
including energy spent heating the
cabin.
The Range Impacts screen
estimates the influence of the main
factors impacting vehicle range.
After charging is complete, this
information is reset. See“Range
Impacts” underEnergy Information
0 115.
Acceleration/Braking/Coasting
Avoid rapid accelerations and
decelerations.
Electric range is maximized at
89 km/h (55 mph) and less. Use cruise control when
appropriate.
Plan ahead for decelerations and
coast whenever possible. Do not
rush to traffic signals, and do not
shift to N (Neutral) to coast.
The vehicle recovers more energy
while coasting and braking in
L (Low) than in D (Drive) mode.
Using the steering wheel paddle
during deceleration recovers more
energy. See
Regenerative Braking
0 194.
Terrain and Vehicle Speed
Higher speeds and grade changes
use more energy and can
significantly reduce electric range.
Climate Setting
Using the heat and air conditioning
systems decreases the energy
available for electric driving.
Optimal energy efficiency is
achieved when the heat, air
conditioning, and fan are turned off. Use the heated seat feature instead
of climate control system. Heating
the seat 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.
Keep the inside of the windows
clean to reduce fogging, and turn off
the front defroster and rear defogger
when they are not needed.
Avoid driving with the windows open
at highway speeds.
Use the Enhanced Battery Gauge
on the Instrument Cluster to view
the effect of climate control settings
on your estimated range. See
Battery Gauge (High Voltage)
098.
Outside Temperature
On colder days, it is best to plug in
the vehicle overnight, and then
remote start the vehicle.

suspected or an unusual noise is
heard. A coolant loss could indicate
a problem. Have it inspected and
repaired by your dealer.
The following explains the cooling
systems and how to check coolant
levels.
.
High Voltage Battery
. Single Power Inverter Module
(SPIM), Accessory Power
Module (APM), and Charger
Module
. Cabin Heating
High Voltage Battery
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.
Single Power Inverter Module
(SPIM), Accessory Power
Module (APM), and Charger
Module
The SPIM, APM, and charger
module are cooled using a separate
coolant loop. These modules are
kept below a maximum temperature.
If the temperature rises above this
temperature, the electric cooling fan
will turn on to cool the coolant.
Cabin Heating
Cabin heating is maintained by
coolant heated by the Coolant
Heater Control Module (CHCM),
separate from the power electronics
and battery coolant loops. This
module heats the coolant based on
temperature inputs from the cabin
climate control systems.
