Driving and Operating 159
Shifting out of Park
To shift out of P (Park), the vehicle must be
on, the brake pedal must be applied, and
the charge cord must be unplugged.
This vehicle is equipped with an electric
drive unit. The shift lock release button is
designed to prevent inadvertent shifting out
of P (Park) unless the ignition is on, the
brake pedal is applied, and the shift lock
release button is pressed.
Parking the vehicle in extreme cold for
several days without the charge cord
connected may cause the vehicle not to
start. The vehicle will need to be plugged in
to allow the high voltage battery to be
warmed sufficiently.The shift lock is always functional except in
the case of an uncharged or low charged
12-volt battery (less than 9 volts).
If the vehicle has an uncharged 12-volt
battery or a 12-volt battery with low
voltage, try charging or jump starting the
12-volt battery.

7. After releasing the shift lever, it will return to the center position.
Extended Parking
It is best not to park with the vehicle
running. If the vehicle is left running, be
sure it will not move and there is adequate
ventilation.
See Shifting Into Park 0158.
If the vehicle is left parked and running with
the RKE transmitter outside the vehicle, it
will continue to run for up to an hour.
If the vehicle is left parked and running with
the RKE transmitter inside the vehicle, it will
continue to run for up to two hour.
The timer will reset if the vehicle is taken
out of P (Park) while it is running.

Driving and Operating 163
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.

14637856) - 2021 - CRC - 10/2/20
164 Driving and Operating
Braking in Emergencies
ABS allows steering and braking at the same
time. In many emergencies, steering can
help even more than braking.
Electric Parking Brake
The vehicle has an Electric Parking Brake
(EPB). The EPB can always be activated, even
if the vehicle is off.
The system has a red parking brake status
light and an amber parking brake warning
light.
There are also parking brake-related Driver
Information Center (DIC) messages.In case of insufficient electrical power, the
EPB cannot be applied or released.
Before leaving the vehicle, check the red
parking brake status light to ensure that the
parking brake is applied.
EPB Apply
To apply the EPB:
1. Be sure the vehicle is at a complete stop.
2. Pull the EPB switch momentarily.
The red parking brake status light will flash
and then stay on once the EPB is fully
applied. If the red parking brake status light
flashes continuously, then the EPB is only
partially applied or there is a problem with
the EPB. A DIC message will display. Release
the EPB and try to apply it again. If the
light does not come on, or keeps flashing,
have the vehicle serviced. Do not drive the
vehicle if the red parking brake status light
is flashing. See your dealer.
If the amber parking brake warning light is
on, lift up on the EPB switch and hold it up.
Continue to hold the switch until the red
parking brake status light remains on. If the
amber parking brake warning light is still
on, see your dealer. If the EPB is applied while the vehicle is
moving, the vehicle will decelerate as long
as the switch is held up. If the switch is held
up until the vehicle comes to a stop, the
EPB will remain applied.
The vehicle may automatically apply the EPB
in some situations when the vehicle is not
moving. This is normal, and is done to
periodically check the correct operation of
the EPB system.
If the EPB fails to apply, block the rear
wheels to prevent vehicle movement.
EPB Release
To release the EPB:
1. Press POWER
Oto start the vehicle.
2. Apply and hold the brake pedal.
3. Press momentarily on the EPB switch.
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.

Driving and Operating 165
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. 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. SeeDefensive Driving
0 148.
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.
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.

Chevrolet Bolt EV Owner Manual (GMNA-Localizing-U.S./Canada-
14637856) - 2021 - CRC - 10/2/20
166 Driving and Operating
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 0160.
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 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.

Driving and Operating 167
.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.

Once the vehicle speed reaches about
40 km/h (25 mph) or more, briefly press
+RES. The vehicle returns to the previous set
speed.
Increasing Speed While Using Cruise Control
If the cruise control system is already
activated:
.Press and hold +RES until the vehicle
accelerates to the desired speed, then
release it.
.To increase the speed in small increments,
briefly press +RES. For each press, the
vehicle goes about 1 km/h (1 mph) faster.
The speedometer reading can be displayed
in either English or metric units. See
Instrument Cluster 079. The increment
value used depends on the units displayed.
Reducing Speed While Using Cruise Control
If the cruise control system is already
activated:
.Press and hold −SET until the desired
lower speed is reached, then release it.
.To slow down in small increments, briefly
press −SET. For each press, the vehicle
goes about 1 km/h (1 mph) slower. The speedometer reading can be displayed
in either English or metric units. See

value used depends on the units displayed.
Passing Another Vehicle While Using Cruise
Control
Use the accelerator pedal to increase the
vehicle speed. When you take your foot off
the pedal, the vehicle will slow down to the
previous set cruise speed. While pressing the
accelerator pedal or shortly following the
release to override cruise control, briefly
pressing −SET will result in cruise control set
to the current vehicle speed.
Using Cruise Control on Hills
How well the cruise control works on hills
depends upon the vehicle speed, load, and
the steepness of the hills. When going up
steep hills, you might have to step on the
accelerator pedal to maintain the vehicle
speed. When going downhill, you might
have to brake or shift to a lower gear to
keep your speed down. If the brake pedal is
applied, cruise control will disengage.

Front/Rear Overhead View :Displays a Front
or Rear Overhead View of the vehicle.
Touching the button will toggle between the
two views.
Side Forward/Rearward View : Displays a
view that shows objects next to the front or
rear sides of the vehicle. Touch Side
Forward/Rearward View on the infotainment
display when a camera view is active.
Touching the button multiple times will
toggle between forward and rearward views.
Park Assist and RCTA are not available when
Side Forward/Rearward view is active.
Park Assist
If equipped with Rear Park Assist (RPA), as
the vehicle moves at speeds of less than
8 km/h (5 mph) the sensors on the bumpers
may detect objects up to 2.3 m (7.5 ft)
behind the vehicle within a zone of 25 cm
(10 in) high off the ground and below
bumper level. These detection distances may
be shorter during warmer or humid weather.
Blocked sensors will not detect objects and
can also cause false detections. Keep the
sensors clean of mud, dirt, snow, ice, and
slush; and clean sensors after a car wash in
freezing temperatures.
{Warning
The Park Assist system does not detect
children, pedestrians, bicyclists, animals,
or objects located below the bumper or
that are too close or too far from the
vehicle. It is not available at speeds
greater than 8 km/h (5 mph). To prevent
injury, death, or vehicle damage, even
with Park Assist, always check the area
around the vehicle and check all mirrors
before moving forward or backing.
The instrument cluster may have a Park
Assist display with bars that show “distance
to object” and object location information
for RPA. As the object gets closer, more bars light up and the bars change color from
yellow to amber to red. When an object is
first detected in the rear, one beep will be
heard from the rear. When an object is very
close, <0.6 m (2 ft) in the vehicle rear, five
beeps will sound from the rear depending
on object location.
Rear Cross Traffic Alert (RCTA)
If equipped, when the vehicle is shifted into
R (Reverse), RCTA uses a red warning
triangle with a left or right pointing arrow
on the infotainment display to warn of
traffic coming from the left or right. This
system detects objects coming from up to
20 m (65 ft) from the left or right side of
the vehicle. When an object is detected,
three beeps sound from the left or right,
depending on the direction of the detected
vehicle.
Assistance Systems for Driving
If equipped, when driving the vehicle in a
forward gear, Forward Collision Alert (FCA),
Lane Departure Warning (LDW), Lane Keep
Assist (LKA), Side Blind Zone Alert (SBZA),
Lane Change Alert (LCA), Automatic
Emergency Braking (AEB), and/or the Front
Pedestrian Braking (FPB) System can help to
avoid a crash or reduce crash damage.
