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 Electric Parking Brake (EPB) can be
applied when the vehicle is on or off.
If there is not enough electrical power, the
EPB cannot be applied or released. To
prevent draining the battery, avoid
unnecessary repeated cycles of the EPB.The system has a red EPB status light and
an amber service EPB warning light. See
Electric Parking Brake Light
0116 and
Service Electric Parking Brake Light 0116.
There are also parking brake-related Driver
Information Center (DIC) messages.
Before leaving the vehicle, check the red EPB
status light to ensure that the EPB is
applied.
If a message displays on the DIC indicating
the electric drive unit is unable to shift, the
service EPB light is on, and the EPB light
flashes at the same time, the system must
be reset. Start the vehicle, apply the EPB,
and then release it. The message and light
should turn off. See Electric Parking Brake
Light 0116 and
Service Electric Parking Brake Light 0116.EPB Apply
To apply the EPB:
1. Be sure the vehicle is at a complete stop.
2. Press the EPB switch.
The red EPB status light will flash and then
stay on once the EPB is fully applied. If the
red EPB 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
EPB light is flashing. See your dealer.
If the amber service EPB warning light is on,
press the EPB switch. Continue to hold the
switch until the red EPB status light remains
on. If the amber service EPB warning light is
on, see your dealer.
If the EPB is applied while the vehicle is
moving, the vehicle will decelerate as long
as the switch is pressed. If the switch is
pressed 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, or as required by other
safety functions that utilize the EPB.
If the EPB fails to apply, block the rear
wheels to prevent vehicle movement.
EPB Release
To release the EPB:
1. Turn the vehicle on.
2. Apply and hold the brake pedal.

16702912) - 2024 - CRC - 1/17/23
206 Driving and Operating
3. Press the EPB switch.
The EPB is released when the red parking
brake status light is off.
If the amber service EPB warning light is on,
release the EPB by pressing and holding the
EPB switch. 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.
If you are towing a trailer and parking on a
hill, see Driving Characteristics and Towing
Tips 0294.
Automatic EPB Release
The EPB automatically releases 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. See Defensive Driving
0 183.
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
Regenerative braking takes some of the
energy from the moving vehicle and turns it
back into electrical energy. This energy is
then stored back into the high voltage
battery system, contributing to increased
energy efficiency.
Regenerative power may be limited when
the battery is near full charge or cold. See
“Regenerative Power Limited”
underPower
Indicator Gauge 0111. Regenerative braking
supplements your vehicle’s conventional
brakes, especially when going downhill. See
Hill and Mountain Roads 0190.

Chevrolet Silverado EV Owner Manual (GMNA-Localizing-U.S./Canada-
16702912) - 2024 - CRC - 1/17/23
Driving and Operating 207
{Warning
Do not charge your vehicle’s battery
above an 80% charge if you are going to
drive down long, steep grades such as
mountain passes. This provides room in
the battery for regenerative braking to
supplement your conventional brakes
during the descent. This is especially
important when towing a trailer, which
puts additional stress on your vehicle’s
braking system.
See“Charge Now” underCharging 0123
for information on setting charge limits.
See Hill and Mountain Roads 0190 for
important information about driving on
grades.
The brake system uses regenerative braking,
conventional hydraulic braking, or a
combination of both as appropriate.
Regen on Demand
If equipped, 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. See
One-Pedal Driving 0203.
If the vehicle 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.
If the vehicle is on a steep grade, the brake
pedal must be used to hold the vehicle. When available regenerative braking power
is limited, the hydraulic brakes may be
applied to make up the difference.
Cruise control will turn off and the brake
lamps may come on when this feature is
activated.
Avoid using Regen on Demand under
slippery road conditions. 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 Electronic Stability Control (ESC).
These systems help limit wheel spin and
assist the driver in maintaining control,
especially on slippery road conditions.
TCS activates if it senses 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
vehicle power to limit wheel spin.

This vehicle is equipped with four-wheel
steering. This feature steers the vehicle with
all four wheels, which reduces the vehicle
turn diameter and improves maneuverability
of the vehicle.
At slower speeds the front and rear wheels
will turn in opposite directions. This helps
the vehicle make tighter turns, such as
during parking, cornering and turning into
tight spaces. At higher speeds the front and
rear wheels will turn in the same direction.
This improves stability of the vehicle during
lane changes and wide turns
When the vehicle is shut-off, the rear
steering angle will automatically return to
the forward position.
Four-wheel steering is not operational when
Super Cruise is active. See Super Cruise
0 227.
