Sensors
Indicator Light and Solar Sensor (ILSS)
The ILSS is on top of the instrument panel,
near the windshield, where it monitors solar
intensity.
The climate control system uses the sensor
information to adjust the temperature, fan
speed, recirculation, and air delivery mode
for best comfort.
Do not cover the sensor; otherwise the
automatic climate control system may not
work properly.
Humidity Sensor
The humidity sensor is near the base of the
inside rearview mirror. The climate control
system uses the sensor information to
adjust the temperature and recirculation for
best comfort.Outside Air Temperature Sensor
The outside air temperature sensor is behind
the front grille of the vehicle. The vehicle
uses the sensor information to display
outside air temperature. The climate control
system uses the information to adjust the
climate system operation.
Air Vents
Adjustable air vents are in the center and on
the side of the instrument panel.
Move the slats to change the direction of
the airflow. The center air vent does not
close completely.
Move the slats to change the direction of

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.

14637856) - 2021 - CRC - 10/2/20
Driving and Operating 151
.Slow down and adjust your driving
according to weather conditions. Stopping
distance can be longer and vehicle control
can be affected when traction is reduced
by water, snow, ice, gravel, or other
material on the road. Learn to recognize
warning clues—such as enough water,
ice, or packed snow on the road to make
a mirrored surface —and slow down
when you have any doubt.
.Try to avoid sudden steering, acceleration,
or braking, including reducing vehicle
speed by shifting to a lower gear. Any
sudden changes could cause the tires to
slide.
Remember: Antilock brakes help avoid only
the braking skid.
Driving on Wet Roads
Rain and wet roads can reduce vehicle
traction and affect your ability to stop and
accelerate. Always drive slower in these
types of driving conditions and avoid driving
through large puddles and deep-standing or
flowing water.
{Warning
Wet brakes can cause crashes. They
might not work as well in a quick stop
and could cause pulling to one side. You
could lose control of the vehicle.
After driving through a large puddle of
water or a car/vehicle wash, lightly apply
the brake pedal until the brakes work
normally.
Flowing or rushing water creates strong
forces. Driving through flowing water
could cause the vehicle to be carried
away. If this happens, you and other
vehicle occupants could drown. Do not
ignore police warnings and be very
cautious about trying to drive through
flowing water.
Hydroplaning
Hydroplaning is dangerous. Water can build
up under the vehicle's tires so they actually
ride on the water. This can happen if the
road is wet enough and you are going fast
enough. When the vehicle is hydroplaning, it
has little or no contact with the road. There is no hard and fast rule about
hydroplaning. The best advice is to slow
down when the road is wet.
Other Rainy Weather Tips
Besides slowing down, other wet weather
driving tips include:
.Allow extra following distance.
.Pass with caution.
.Keep windshield wiping equipment in
good shape.
.Keep the windshield washer fluid reservoir
filled.
.Have good tires with proper tread depth.
.Turn off cruise control.
Hill and Mountain Roads
Driving on steep hills or through mountains
is different than driving on flat or rolling
terrain.
.Keep the vehicle serviced and in good
shape.
.Check all fluid levels and brakes, tires,
cooling system, and electric drive unit.
.Keep the vehicle in gear when going
down steep or long hills.

14637856) - 2021 - CRC - 10/2/20
Driving and Operating 153
The Traction Control System (TCS) must be
turned off by pressing the TCS/ESC button.
Traction control is not completely off, but
will only engage if the maneuver can cause
damage to the electric drive unit.
{Warning
If the vehicle's tires spin at high speed,
they can explode, and you or others
could be injured. The vehicle can
overheat, causing an underhood
compartment fire or other damage. Spin
the wheels as little as possible and avoid
going above 56 km/h (35 mph).
Rocking the Vehicle to Get it Out
Turn the steering wheel left and right to
clear the area around the front wheels. Turn
off TCS. Shift back and forth between
R (Reverse) and a low forward gear, spinning
the wheels as little as possible. To prevent
electric drive unit wear, wait until the
wheels stop spinning before shifting gears.
Release the accelerator pedal while shifting,
and press lightly on the accelerator pedal
when the electric drive unit is in gear.
Slowly spinning the wheels in the forward
and reverse directions causes a rocking
motion that could free the vehicle. If thatdoes not get the vehicle out after a few
tries, it might need to be towed out. See
Towing the Vehicle
0240.
Vehicle Load Limits
It is very important to know how much
weight the vehicle can carry. This
weight is called the vehicle capacity
weight and includes the weight of all
occupants, cargo, and all
nonfactory-installed options. Two labels
on the vehicle may show how much
weight it may properly carry: the Tire
and Loading Information label and the
Certification label.
{Warning
Do not load the vehicle any heavier
than the Gross Vehicle Weight Rating
(GVWR), or either the maximum
front or rear Gross Axle Weight
Rating (GAWR). This can cause
systems to break and change the
way the vehicle handles. This could
cause loss of control and a crash.
(Continued)
Warning (Continued)
Overloading can also reduce stopping
performance, damage the tires, and
shorten the life of the vehicle.
Tire and Loading Information Label
Label Example
A vehicle-specific Tire and Loading
Information label is attached to the
vehicle's center pillar (B-pillar). The Tire
and Loading Information label shows
the number of occupant seating

156 Driving and Operating
{Warning
Things inside the vehicle can strike
and injure people in a sudden stop or
turn, or in a crash.
.Put things in the cargo area of the
vehicle. In the cargo area, put
them as far forward as possible.
Try to spread the weight evenly.
.Never stack heavier things, like
suitcases, inside the vehicle so
that some of them are above the
tops of the seats.
.Do not leave an unsecured child
restraint in the vehicle.
.Secure loose items in the vehicle.
.Do not leave a seat folded down
unless needed.
Starting and Operating
New Vehicle Break-In

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 083.
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. While operating in One-Pedal Driving, the
electric parking brake may apply in some
circumstances. This can occur when:
.Driving on slopes.
.The driver’s door is open.
.The vehicle has remained stationary for
5 minutes.
.There is a problem with the propulsion
system.
To drive again, depress the accelerator
pedal, and the electric parking brake will
automatically disengage.
One-Pedal Driving may shift the car into
P (Park) if the vehicle is pushed once it has
been stopped or if a problem with the
propulsion system develops.
Brakes
Antilock Brake System (ABS)
The Antilock Brake System (ABS) helps
prevent a braking skid and maintain steering
while braking hard. ABS performs a system check when the
vehicle is first driven. A momentary motor
or clicking noise may be heard while this
test is going on, and the brake pedal may
move slightly. This is normal.
If there is a problem with ABS, this warning
light stays on. See
Antilock Brake System
(ABS) Warning Light 086.
ABS does not change the time needed to
get a foot on the brake pedal and does not
always decrease stopping distance. If you
get too close to the vehicle ahead, there will
not be enough time to apply the brakes if
that vehicle suddenly slows or stops. Always
leave enough room ahead to stop, even
with ABS.
Using ABS
Do not pump the brakes. Just hold the brake
pedal down firmly. Hearing or feeling ABS
operate is normal.
