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
0 253.

Driving and Operating 147
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” under. See Energy Information
0 97.
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
0165.
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)
0 82.
Outside Temperature
On colder days, it is best to plug in the
vehicle overnight, and then remote start the
vehicle.
Allow the vehicle to warm up for
20 minutes before driving.
If possible, use a level 2 (240 volt) high
power charge station for best results. This
allows the interior of the vehicle and high
voltage battery to warm to optimal
temperature.

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.
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.
Hybrid Cooling System Pressure Caps
The hybrid cooling system reservoirs have
tamper resistant pressure caps. The coolant
should only be serviced by a qualified
technician.
Checking Coolant
The coolant needs to be replaced at the
appropriate interval. See Maintenance
Schedule 0253.
The coolant reservoirs are in the underhood
compartment. See Underhood Compartment
Overview 0200.
