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.

Driving and Operating 191
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
0 103. 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.
Braking in Emergencies
ABS allows steering and braking at
the same time. In many
emergencies, steering can help
even more than braking.

3. Press momentarily on the EPBswitch.
The EPB is released when the red
parking brake status light is off.
If the amber parking brake warning
light is on, release the EPB by
pressing down on the EPB switch
and holding it down. Continue to
hold the switch until the red parking
brake status light is off. If either light
stays on after release is attempted,
see your dealer.
Caution
Driving with the parking brake on
can overheat the brake system
and cause premature wear or
damage to brake system parts.
Make sure that the parking brake
is fully released and the brake
warning light is off before driving.
Automatic EPB Release
The EPB will automatically release if
the vehicle is running, placed into
gear, and an attempt is made to drive away. Avoid rapid acceleration
when the EPB is applied, to
preserve parking brake lining life.
Brake Assist
Brake Assist detects rapid brake
pedal applications due to
emergency braking situations and
provides additional braking to
activate the Antilock Brake System
(ABS) if the brake pedal is not
pushed hard enough to activate
ABS normally. Minor noise, brake
pedal pulsation, and/or pedal
movement during this time may
occur. Continue to apply the brake
pedal as the driving situation
dictates. Brake Assist disengages
when the brake pedal is released.
Hill Start Assist (HSA)
{Warning
Do not rely on the HSA feature.
HSA does not replace the need to
pay attention and drive safely.
(Continued)
Warning (Continued)
You may not hear or feel alerts or
warnings provided by this system.
Failure to use proper care when
driving may result in injury, death,
or vehicle damage. See
Defensive Driving0173.
When the vehicle is stopped on a
grade, Hill Start Assist (HSA)
prevents the vehicle from rolling in
an unintended direction during the
transition from brake pedal release
to accelerator pedal apply. The
brakes release when the accelerator
pedal is applied. If the accelerator
pedal is not applied within a few
minutes, the Electric Parking Brake
will apply. The brakes may also
release under other conditions. Do
not rely on HSA to hold the vehicle.
HSA is available when the vehicle is
facing uphill in a forward gear,
or when facing downhill in
R (Reverse). The vehicle must
come to a complete stop on a grade
for HSA to activate.

194 Driving and Operating
Regenerative Braking
Some braking energy from the
moving vehicle is turned back into
electrical energy. This energy is
then stored back into the high
voltage battery system, increasing
energy efficiency.
Regen on Demand
Regen on Demand allows increased
deceleration by pressing and
holding the steering wheel paddle.
It works in D (Drive) and L (Low).
The accelerator pedal can be used
to manage deceleration while using
Regen on Demand.Cruise control will turn off and the
brake lamps may come on when
this feature is activated.
If the vehicle is in D (Drive) and is
brought to a complete stop while the
Regen on Demand paddle is held,
the vehicle will not creep forward
when the paddle is released. The
accelerator pedal must be pressed
to move the vehicle forward. See
“One-Pedal Driving”
underElectric
Drive Unit 0187.
If the vehicle is on a steep grade,
the brake pedal must be used to
hold the vehicle.
Regenerative power may be limited
when the battery is near full charge
or cold. The regen battery icon will
appear gray when limited. The
regen power limit is also displayed
as a horizontal bar on the power
indicator gauge.
Avoid using Regen On Demand
under slippery road conditions.
Under Regenerative Power Limited
Condition, the amount of vehicle
deceleration will be limited. Use the
brake pedal as the primary braking
device.
Ride Control Systems
Traction Control/
Electronic Stability
Control
System Operation
The vehicle has a Traction Control
System (TCS) and StabiliTrak/
Electronic Stability Control (ESC),
an electronic stability control
system. These systems help limit
wheel slip and assist the driver in
maintaining control, especially on
slippery road conditions.
TCS activates if it senses that any
of the drive wheels are spinning or
beginning to lose traction. When this
happens, TCS applies the brakes to
the spinning wheels and reduces
propulsion system power to limit
wheel spin.
StabiliTrak/ESC activates when the
vehicle senses a difference between
the intended path and the direction
the vehicle is actually traveling.
StabiliTrak/ESC selectively applies
braking pressure to any one of the

Chevrolet BOLT EV Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-
13556250) - 2020 - CRC - 2/11/20
Driving and Operating 195
vehicle wheel brakes to assist the
driver in keeping the vehicle on the
intended path.
If cruise control is being used and
TCS or StabiliTrak/ESC begins to
limit wheel spin, cruise control will
disengage. Cruise control may be
turned back on when road
conditions allow.
Both systems come on
automatically when the vehicle is
started and begins to move. The
systems may be heard or felt while
they are operating or while
performing diagnostic checks. This
is normal and does not mean there
is a problem with the vehicle.
It is recommended to leave both
systems on for normal driving
conditions, but it may be necessary
to turn TCS off if the vehicle gets
stuck in sand, mud, ice, or snow.
See“Turning the Systems Off and
On” later in this section.
The indicator light for both systems
is in the instrument cluster. This
light will:
.
Flash when TCS is limiting
wheel spin.
. Flash when StabiliTrak/ESC is
activated.
. Turn on and stay on when either
system is not working.
If either system fails to turn on or to
activate, a message displays in the
Driver Information Center (DIC), and
dcomes on and stays on to
indicate that the system is inactive
and is not assisting the driver in
maintaining control. The vehicle is
safe to drive, but driving should be
adjusted accordingly.
If
dcomes on and stays on:
1. Stop the vehicle. 2. Turn the vehicle off and wait
15 seconds.
3. Start the vehicle.
Drive the vehicle. If
dcomes on and
stays on, the vehicle may need
more time to diagnose the problem.
If the condition persists, see your
dealer.
