Propulsion Power Messages
PROPULSION POWER IS REDUCED
This message displays when the vehicle's
propulsion power is reduced. A reduction in
propulsion power can affect the vehicle's
ability to accelerate. If this message is on,
but there is no observed reduction in
performance, proceed to your destination.
Under certain conditions the performance
may be reduced the next time the vehicle is
driven. The vehicle may be driven while this
message is on, but maximum acceleration
and speed may be reduced. Anytime this
message stays on, or displays repeatedly,
the vehicle should be taken to your dealer
for service as soon as possible.
This message is commonly displayed when
the high voltage battery charge level is low.
The vehicle is limiting power to maximize
range.
This message can display when the vehicle
is parked during extreme cold conditions
without being plugged in. While driving the

vehicle speed may be reduced until the high
voltage battery is conditioned.
Under certain operating conditions,
propulsion will be disabled. Try restarting
after the ignition has been off for
30 seconds.
Vehicle Speed Messages
SPEED LIMITED TO XXX KM/H (MPH)

IntelliBeam System
If equipped, this system turns the vehicle's
high-beam headlamps on and off according
to surrounding traffic conditions.
The system turns the high-beam headlamps
on when it is dark enough and there is no
other traffic present.
This light comes on in the instrument
cluster when the IntelliBeam system is
enabled.

Exit Lighting
Some exterior lamps and interior lamps
come on at night, or in areas with limited
lighting, when the driver door is opened
after the ignition is turned off. The exterior
lamps and interior lamps remain on for a
set amount of time, then automatically
turn off.
The exterior lamps turn off immediately
by turning the exterior lamp control off.
This feature can be changed. See Vehicle
Personalization 0101.
Battery Power Protection
The battery saver feature is designed to
protect the vehicle's 12-volt battery.
If some interior lamps and/or the headlamps
are left on and the vehicle is turned off, the
battery rundown protection system
automatically turns the lamp off after
some time.
Exterior Lighting Battery Saver
The exterior lamps turn off about 10 minutes
after the ignition is turned off, if the parking
lamps or headlamps have been manually
left on. This protects against draining the
battery. To restart the 10-minute timer, turn
the exterior lamp control to the off position
and then back to the parking lamp or
headlamp position.
To keep the lamps on for more than
10 minutes, the ignition must be on.

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
148 Driving and Operating
Vehicle Charging/Maintenance
Charging
Keep the vehicle plugged in, even when fully
charged, to keep the battery temperature
ready for the next drive. This is important
when outside temperatures are extremely
hot or cold.
Maintenance
Always keep the tires properly inflated and
the vehicle properly aligned.
The weight of excess cargo in the vehicle
affects efficiency and range. Avoid carrying
more than is needed.
Avoid unnecessary use of electrical
accessories. Power used for functions other
than propelling the vehicle will reduce EV
range.
Using a rooftop carrier will reduce efficiency
due to additional weight and drag.
Distracted Driving
Distraction comes in many forms and can
take your focus from the task of driving.
Exercise good judgment and do not let other
activities divert your attention away from
the road. Many local governments haveenacted laws regarding driver distraction.
Become familiar with the local laws in
your area.
To avoid distracted driving, keep your eyes
on the road, keep your hands on the
steering wheel, and focus your attention on
driving.
.Do not use a mobile phone in demanding
driving situations. Use a hands-free
method to place or receive necessary
phone calls.
.Watch the road. Do not read, take notes,
or look up information on mobile phones
or other electronic devices.
.Designate a front seat passenger to
handle potential distractions.
.Become familiar with vehicle features
before driving, such as programming
favorite radio stations and adjusting
climate control and seat settings. Program
all trip information into any navigation
device prior to driving.
.Wait until the vehicle is parked to
retrieve items that have fallen to the
floor.
.Stop or park the vehicle to tend to
children.
.Keep pets in an appropriate carrier or
restraint.
.Avoid stressful conversations while
driving, whether with a passenger or on a
mobile phone.
{Warning
Taking your eyes off the road too long or
too often could cause a crash resulting in
injury or death. Focus your attention on
driving.
Refer to the Infotainment section for more
information on using that system, including
pairing and using a mobile phone.
Defensive Driving
Defensive driving means “always expect the
unexpected.” The first step in driving
defensively is to wear the seat belt.
.Assume that other road users
(pedestrians, bicyclists, and other drivers)
are going to be careless and make
mistakes. Anticipate what they might do
and be ready.
.Allow enough following distance between
you and the driver in front of you.
.Focus on the task of driving.
