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 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.

Chevrolet Bolt EV Owner Manual (GMNA-Localizing-U.S./Canada-
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.

14637856) - 2021 - CRC - 10/2/20
Driving and Operating 149
Impaired Driving
Death and injury associated with impaired
driving is a global tragedy.
{Warning
Drinking alcohol or taking drugs and then
driving is very dangerous. Your reflexes,
perceptions, attentiveness, and judgment
can be affected by even a small amount
of alcohol or drugs. You can have a
serious—or even fatal —collision if you
drive after drinking or taking drugs.
Do not drive while under the influence of
alcohol or drugs, or ride with a driver
who has been drinking or is impaired by
drugs. Find alternate transportation
home; or if you are with a group,
designate a driver who will remain sober.
Control of a Vehicle
Braking, steering, and accelerating are
important factors in helping to control a
vehicle while driving.
Braking
Braking action involves perception time and
reaction time. Deciding to push the brake
pedal is perception time. Actually doing it is
reaction time.
Average driver reaction time is about
three-quarters of a second. In that time, a
vehicle moving at 100 km/h (60 mph) travels
20 m (66 ft), which could be a lot of
distance in an emergency.
Helpful braking tips to keep in mind include:
.Keep enough distance between you and
the vehicle in front of you.
.Avoid needless heavy braking.
.Keep pace with traffic.
Steering
Caution
To avoid damage to the steering system,
do not drive over curbs, parking barriers,
or similar objects at speeds greater than
3 km/h (1 mph). Use care when driving
over other objects such as lane dividers
and speed bumps. Damage caused by
misuse of the vehicle is not covered by
the vehicle warranty.
Variable Effort Steering
The vehicle has a steering system that
varies the amount of effort required to steer
the vehicle in relation to the speed of the
vehicle.
The amount of steering effort required is
less at slower speeds to make the vehicle
more maneuverable and easier to park. At
faster speeds, the steering effort increases
to provide a sport-like feel to the steering.
This provides maximum control and stability.
Electric Power Steering
The vehicle has electric power steering.
It does not have power steering fluid.
Regular maintenance is not required.
