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.

Caution
Spinning the tires excessively
may damage the electric drive
unit. The repair will not be
covered by the vehicle warranty.
If you are stuck, do not spin the
tires.
When stopping on a steep hill, use
the brakes to hold the vehicle in
place.
When shifting to P (Park) on a hill,
use the brakes to hold the vehicle
then shift to P (Park).
L : This position reduces vehicle
speed without using the brakes. Use
L (Low) on very steep hills and in
stop-and-go traffic.
One-Pedal Driving
With One-Pedal Driving, the
accelerator pedal can be used to
control the deceleration of the
vehicle down to a complete stop.
Completely lifting off the accelerator
pedal will result in aggressive
deceleration. Partially lifting off the
accelerator pedal will allow the
deceleration of the vehicle to be
adjusted as desired.
The amount of deceleration may
vary under Regenerative Power
Limited condition. See Power
Indicator Gauge 099.
Use the brake pedal if emergency
braking is required.
To use One-Pedal Driving, place the
vehicle in L (Low). Press the
accelerator pedal to the desired
speed. The deceleration provided by
One-Pedal Driving provides full
regenerative braking and helps
increase energy efficiency. The
brake lamps may come on when the
accelerator pedal is released or
during substantial deceleration from
regenerative braking.

204 Driving and Operating
Forward Collision Alert
(FCA) System
If equipped, the FCA system may
help to avoid or reduce the harm
caused by front-end crashes. When
approaching a vehicle ahead too
quickly, FCA provides a red flashing
alert on the windshield and rapidly
beeps. FCA also lights an amber
visual alert if following another
vehicle much too closely. FCA
detects vehicles within a distance of
approximately 60 m (197 ft) and
operates at speeds above
8 km/h (5 mph).
{Warning
FCA is a warning system and
does not apply the brakes. When
approaching a slower-moving or
stopped vehicle ahead too rapidly,
or when following a vehicle too
closely, FCA may not provide a
warning with enough time to help
avoid a crash. It also may not
provide any warning at all. FCA(Continued)
Warning (Continued)
does not warn of pedestrians,
animals, signs, guardrails,
bridges, construction barrels,
or other objects. Be ready to take
action and apply the brakes.
Detecting the Vehicle Ahead
FCA warnings will not occur unless
the FCA system detects a vehicle
ahead. When a vehicle is detected,
the vehicle ahead indicator will
display green. Vehicles may not be
detected on curves, highway exit
ramps, or hills, due to poor visibility;
or if a vehicle ahead is partially
blocked by pedestrians or other
objects. FCA will not detect another
vehicle ahead until it is completely
in the driving lane.
{Warning
FCA does not provide a warning
to help avoid a crash, unless it
detects a vehicle. FCA may not
detect a vehicle ahead if the FCA
sensor is blocked by dirt, snow,
or ice, or if the windshield is
damaged. It may also not detect a
vehicle on winding or hilly roads,
or in conditions that can limit
visibility such as fog, rain,
or snow, or if the headlamps or
windshield are not cleaned or in
proper condition. Keep the
windshield, headlamps, and FCA
sensors clean and in good repair.

208 Driving and Operating
Warning (Continued)
Be ready to take action and apply
the brakes. For more information,
seeDefensive Driving 0173.
Keep the windshield, headlamps,
and FPB sensor clean and in
good repair.
FPB can be set to Off, Alert, or Alert
and Brake through vehicle
personalization. See “Collision/
Detection Systems” underVehicle
Personalization 0121.
Detecting the Pedestrian
Ahead
FPB alerts and automatic braking
will not occur unless the FPB
system detects a pedestrian. When a nearby pedestrian is detected in
front of the vehicle, the pedestrian
ahead indicator will display amber.
Front Pedestrian Alert
When the vehicle approaches a
pedestrian ahead too rapidly, the
red FPB alert display will flash on
the windshield. Eight rapid
high-pitched beeps will sound from
the front. When this Pedestrian Alert
occurs, the brake system may
prepare for driver braking to occur
more rapidly which can cause a
brief, mild deceleration. Continue to
apply the brake pedal as needed.
Cruise control may be disengaged
when the Front Pedestrian Alert
occurs.
Automatic Braking
If FPB detects it is about to crash
into a pedestrian directly ahead, and
the brakes have not been applied,
FPB may automatically brake
moderately or brake hard. This can
help to avoid some very low speed
pedestrian crashes or reduce
pedestrian injury. FPB can
automatically brake to detected
pedestrians between 8 km/h (5 mph)
and 80 km/h (50 mph). Automatic
braking levels may be reduced
under certain conditions, such as
higher speeds.
If this happens, Automatic Braking
may engage the Electric Parking
Brake (EPB) to hold the vehicle at a
stop. Release the EPB. A firm press
of the accelerator pedal will also
release Automatic Braking and
the EPB.

212 Driving and Operating
Warning (Continued)
If LKA only detects lane markings
on one side of the road, it will
only assist or provide an LDW
alert when approaching the lane
on the side where it has detected
a lane marking. Even with LKA
and LDW, you must steer the
vehicle. Always keep your
attention on the road and
maintain proper vehicle position
within the lane, or vehicle
damage, injury, or death could
occur. Always keep the
windshield, headlamps, and
camera sensors clean and in
good repair. Do not use LKA in
bad weather conditions or on
roads with unclear lane markings,
such as construction zones.
{Warning
Using LKA while towing a trailer
or on slippery roads could cause
loss of control of the vehicle and
a crash. Turn the system off.
How the System Works
LKA uses a camera sensor installed
on the windshield ahead of the
rearview mirror to detect lane
markings. It may provide brief
steering assist if it detects an
unintended lane departure. It may
further provide an audible alert or
the driver seat may pulse indicating
that a lane marking has been
crossed.
To turn LKA on and off, press
A
on the steering wheel. If equipped,
the indicator light on the button
comes on when LKA is on and turns
off when LKA is disabled.When on,

Ais green if LKA
is ready to assist. LKA may assist
by gently turning the steering wheel
if the vehicle approaches a detected
lane marking.
Ais amber when
assisting. It may also provide a
Lane Departure Warning (LDW)
alert by flashing
Aamber if the
vehicle crosses a detected lane
marking. Additionally, there may be
three beeps, or the driver seat may
pulse three times, on the right or
left, depending on the lane
departure direction.
Take Steering
The LKA system does not
continuously steer the vehicle.
If LKA does not detect active driver
steering, an alert and chime may be
provided. Steer the vehicle to

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.
