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. SeeMaintenance Schedule
0 271.

152 Driving and Operating
Driving Information
Driving for Better Energy
Efficiency
Use the following tips to help maximize
energy efficiency and driving 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.
Driving 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. Do not shift to N (Neutral) to coast. The vehicle recovers more energy while
coasting and braking with One-Pedal mode
turned on. See
One-Pedal Driving 0167.
Using the Regen on Demand paddle during
deceleration recovers more energy. See
Regenerative Braking 0170.
Terrain and Vehicle Speed
Higher speeds and grade changes use more
energy and can significantly reduce driving
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 features instead of
climate control system. Heating the seat
uses less energy than heating and cooling
the interior.
Use remote start to heat or cool the interior
when the vehicle is plugged in to maximize
the driving 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. 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
driving range. See
Battery Gauge (High
Voltage) 081.
Outside Temperature
On colder days, it is best to plug in the
vehicle overnight, 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 the 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 0271.
The coolant reservoirs are in the underhood
compartment. See Underhood Compartment
Overview 0216.

Service and Maintenance 271
The Additional Required Services are for
vehicles that:
.Carry passengers and cargo within
recommended limits on the Tire and
Loading Information label. SeeVehicle
Load Limits 0158.
.Are driven on reasonable road surfaces
within legal driving limits.
See “Additional Required Services” in the
Maintenance Schedule 0271.
{Warning
Performing maintenance work can be
dangerous and can cause serious injury.
Perform maintenance work only if the
required information, proper tools, and
equipment are available. If they are not,
see your dealer to have a trained
technician do the work. See Doing Your
Own Service Work 0213.
Maintenance Schedule
Tire Rotation and Required Services
Every 12 000 km (7,500 mi)
Tires are rotated to achieve a more uniform
wear for all tires. The first rotation is the
most important. Anytime unusual wear is noticed, rotate the
tires as soon as possible, check for proper
tire inflation pressure, and check for
damaged tires or wheels. If the unusual
wear continues after the rotation, check the
wheel alignment. See
When It Is Time for
New Tires 0245 and
Wheel Replacement 0248.
.Perform Multi-Point Vehicle Inspection.
See Multi-Point Vehicle Inspection (MPVI)
0 272.
.Lubricate body components. See Exterior
Care 0262.
Additional Required Services
Every 36 000 km (22,500 mi)
.Replace passenger compartment air filter.
Or every 24 months, whichever comes
first. More frequent passenger
compartment air filter replacement may
be needed if driving in areas with heavy
traffic, poor air quality, high dust levels,
or environmental allergens. Passenger
compartment air filter replacement may
also be needed if there is reduced airflow,
window fogging, or odors. Your GM
dealer can help determine when to
replace the filter. Every 161 000 km (100,000 mi)
.Replace hood and/or body lift support gas
struts. Or every 10 years, whichever
comes first. See
Gas Strut(s)0224.
Every 240 000 km (150,000 mi)
.Drain and fill vehicle coolant circuits. Or
every five years, whichever comes first.
See Cooling System 0217.
Owner Checks and Services
Every Five Years
.Replace brake fluid.
Every Seven Years
.Replace Air Conditioning Desiccant every
seven years. The air conditioning system
requires maintenance every seven years.
This service requires replacement of the
desiccant to help the longevity and
efficient operation of the air conditioning
system. This service can be complex. See
your dealer.
