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

Chevrolet Bolt EV Owner Manual (GMNA-Localizing-U.S./Canada-
14637856) - 2021 - CRC - 10/2/20
154 Driving and Operating
positions (1), and the maximum vehicle
capacity weight (2) in kilograms and
pounds.
The Tire and Loading Information label
also shows the tire size of the original
equipment tires (3) and the
recommended cold tire inflation
pressures (4). For more information on
tires and inflation seeTires0216 and
Tire Pressure 0221.
There is also important loading
information on the Certification label.
It may show the Gross Vehicle Weight
Rating (GVWR) and the Gross Axle
Weight Rating (GAWR) for the front and
rear axle. See “Certification Label” later
in this section.
“Steps for Determining Correct Load
Limit–
1.Locate the statement "The combined
weight of occupants and cargo
should never exceed XXX kg or
XXX lbs." on your vehicle’s placard.
2.Determine the combined weight of
the driver and passengers that will
be riding in your vehicle.
3.Subtract the combined weight of the
driver and passengers from XXX kg
or XXX lbs.
4.The resulting figure equals the
available amount of cargo and
luggage load capacity. For example,
if the "XXX" amount equals 1400 lbs.
and there will be five 150 lb
passengers in your vehicle, the
amount of available cargo and
luggage load capacity is 650 lbs.
(1400-750 (5 x 150) = 650 lbs.)
5.Determine the combined weight of
luggage and cargo being loaded on
the vehicle. That weight may not
safely exceed the available cargo and
luggage load capacity calculated in
Step 4.
6.If your vehicle will be towing a
trailer, load from your trailer will be
transferred to your vehicle. Consult
this manual to determine how this reduces the available cargo and
luggage load capacity of your
vehicle.”
This vehicle is neither designed nor
intended to tow a trailer.
Example 1
1.Vehicle Capacity Weight for
Example 1 = 453 kg (1,000 lbs).
2.Subtract Occupant Weight @
68 kg (150 lbs) × 2 = 136 kg
(300 lbs).
3.Available Occupant and Cargo
Weight = 317 kg (700 lbs).

are also warned of vehicles rapidly
approaching from up to 70 m (230 ft) behind
the vehicle.
How the System Works
The LCA symbol lights up in the side mirrors
when the system detects a moving vehicle
in the next lane over that is in the side
blind zone or rapidly approaching that zone
from behind. A lit LCA symbol indicates it
may be unsafe to change lanes. Before
making a lane change, check the LCA
display, check mirrors, glance over your
shoulder, and use the turn signals.
Left Side MirrorDisplayRight Side Mirror Display
When the vehicle is started, both outside
mirror LCA displays will briefly come on to
indicate the system is operating. When the
vehicle is in a forward gear, the left or right
side mirror display will light up if a moving
vehicle is detected in the next lane over in
that blind zone or rapidly approaching that zone. If the turn signal is activated in the
same direction as a detected vehicle, this
display will flash as an extra warning not to
change lanes.
LCA can be disabled through vehicle
personalization. See
“Collision/
Detection Systems” underVehicle
Personalization 0101. If LCA is disabled by
the driver, the LCA mirror displays will not
light up.
When the System Does Not Seem to
Work Properly
The LCA system requires some driving for
the system to calibrate to maximum
performance. This calibration may occur
more quickly if the vehicle is driven on a
straight highway road with traffic and
roadside objects (e.g., guardrails, barriers).
LCA displays may not come on when
passing a vehicle quickly or for a stopped
vehicle. LCA may alert to objects attached to
the vehicle, such as a bicycle, or object
extending out to either side of the vehicle.
Attached objects may also interfere with the
detection of vehicles. This is normal system
operation; the vehicle does not need service. LCA may not always alert the driver to
vehicles in the next lane over, especially in
wet conditions or when driving on sharp
curves. The system does not need to be
serviced. The system may light up due to
guardrails, signs, trees, shrubs, and other
non-moving objects. This is normal system
operation; the vehicle does not need service.
LCA may not operate when the LCA sensors
in the left or right corners of the rear
bumper are covered with mud, dirt, snow,
ice, or slush, or in heavy rainstorms. For
cleaning instructions, see "Washing the
Vehicle" under
Exterior Care0244. If the
DIC still displays the system unavailable
message after cleaning both sides of the
vehicle toward the rear corners of the
vehicle, see your dealer.
If the LCA displays do not light up when
moving vehicles are in the side blind zone or
rapidly approaching this zone and the
system is clean, the system may need
service. Take the vehicle to your dealer.
Lane Keep Assist (LKA)
If equipped, LKA may help avoid crashes due
to unintentional lane departures. This
system uses a camera to detect lane
markings between 60 km/h (37 mph) and

Chevrolet Bolt EV Owner Manual (GMNA-Localizing-U.S./Canada-
14637856) - 2021 - CRC - 10/2/20
180 Driving and Operating
180 km/h (112 mph). It may assist by gently
turning the steering wheel if the vehicle
approaches a detected lane marking. It may
also provide a Lane Departure Warning
(LDW) alert if the vehicle crosses a detected
lane marking. LKA can be overriden by
turning the steering wheel. This system is
not intended to keep the vehicle centered in
the lane. LKA will not assist and alert if the
turn signal is active in the direction of lane
departure, or if it detects that you are
accelerating, braking or actively steering.
{Warning
The LKA system does not continuously
steer the vehicle. It may not keep the
vehicle in the lane or give a Lane
Departure Warning (LDW) alert, even if a
lane marking is detected.
The LKA and LDW systems may not:
.Provide an alert or enough steering
assist to avoid a lane departure or
crash.
.Detect lane markings under poor
weather or visibility conditions. This
can occur if the windshield or
headlamps are blocked by dirt, snow,(Continued)
Warning (Continued)
or ice; if they are not in proper
condition; or if the sun shines directly
into the camera.
.Detect road edges.
.Detect lanes on winding or hilly roads.
If LKA only detects lane markings on one
side of the road, it will only assist or
provide an LDW alert when approaching
the lane on the side where it has
detected a lane marking. Even with LKA
and LDW, you must steer the vehicle.
Always keep your attention on the road
and maintain proper vehicle position
within the lane, or vehicle damage,
injury, or death could occur. Always keep
the windshield, headlamps, and camera
sensors clean and in good repair. Do not
use LKA in bad weather conditions or on
roads with unclear lane markings, such as
construction zones.
{Warning
Using LKA while towing a trailer or on
slippery roads could cause loss of control
of the vehicle and a crash. Turn the
system off.
How the System Works
LKA uses a camera sensor installed on the
windshield ahead of the rearview mirror to
detect lane markings. It may provide brief
steering assist if it detects an unintended
lane departure. It may further provide an
audible alert or the driver seat may pulse
indicating that a lane marking has been
crossed.
To turn LKA on and off, press
Aon the
steering wheel. If equipped, the indicator
light on the button comes on when LKA is
on and turns off when LKA is disabled.
When on,
Ais white, if equipped,
indicating that the system is not ready to
assist.
Ais green if LKA is ready to
assist. LKA may assist by gently turning the
steering wheel if the vehicle approaches a
detected lane marking.
Ais amber when
assisting. It may also provide a Lane
Departure Warning (LDW) alert by flashing

Utility Interruption of Charging
This vehicle will respond to requests through
the utility company to limit or completely
block electrical power grid usage. This
feature is inactive during DC charging.
A utility interruption of charging will
lengthen the vehicle charge time.
When electrical grid power is completely
blocked, the vehicle will delay charging until
the utility interruption has expired. The
vehicle should be left plugged in so that the
vehicle can automatically begin charging. Changing the charge mode to Immediate or
performing a delayed charging override will
not disable a utility interruption. Unplugging
and plugging the car back in will also not
disable a utility interruption.
A pop-up will appear in the infotainment
display while starting the vehicle following
any utility interruption. See
“Charging
Interrupted or Overridden Pop-Up” under
Programmable Charging 090.
A message will display on the instrument
cluster indicating that a utility interruption
has occurred.
