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.

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.

Chevrolet Bolt EV Owner Manual (GMNA-Localizing-U.S./Canada-
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
152 Driving and Operating
{Warning
Coasting downhill in N (Neutral) or with
the vehicle turned off is dangerous. The
brakes will have to do all the work of
slowing down the vehicle and could
become too hot. Hot brakes may not be
able to slow the vehicle enough to
maintain speed and control. You could
crash. Always have the vehicle running
and in gear when going downhill. This
will allow the electric drive unit to assist
in slowing and maintaining speed.
.Drive at speeds to keep the vehicle in its
own lane. Do not swing wide or cross the
center line.
.Be alert on top of hills. Something could
be in your lane (e.g., stalled car, crash).
.Pay attention to special road signs (e.g.,
falling rocks area, winding roads, long
grades, passing or no-passing zones) and
take appropriate action.
Winter Driving
Driving on Snow or Ice
Snow or ice between the tires and the road
creates less traction or grip, so drive
carefully. Wet ice can occur at about 0 °C
(32 °F) when freezing rain begins to fall.
Avoid driving on wet ice or in freezing rain
until roads can be treated.
For Slippery Road Driving:
.Recommend using D (Drive) in slippery
conditions.
.Accelerate gently. Accelerating too quickly
causes the wheels to spin and makes the
surface under the tires slick.
.Turn on the Traction Control
System (TCS).
.The Antilock Brake System (ABS) improves
vehicle stability during hard stops, but
the brakes should be applied sooner than
when on dry pavement.
.Allow greater following distance and
watch for slippery spots. Icy patches can
occur on otherwise clear roads in shaded
areas. The surface of a curve or an
overpass can remain icy when thesurrounding roads are clear. Avoid sudden
steering maneuvers and braking while
on ice.
.Turn off cruise control.
.Avoid using Regen on Demand paddle.
Blizzard Conditions
Being stuck in snow can be a serious
situation. Stay with the vehicle unless there
is help nearby. If possible, use Roadside
Assistance. See
Roadside Assistance Program
0 266. To get help and keep everyone in
the vehicle safe:
.Turn on the hazard warning flashers.
.Tie a red cloth to an outside mirror.
To save energy, run the vehicle for only
short periods as needed to warm the vehicle
and then shut the vehicle off and partially
close the window. Moving about to keep
warm also helps.
If the Vehicle Is Stuck
Slowly and cautiously spin the wheels to
free the vehicle when stuck in sand, mud,
ice, or snow.

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.
