Electric Parking Brake - GMC Hummer EV 2024 Owner's Manual

GMC Hummer EV Owner Manual (GMNA-Localizing-MidEast-16639039) -
2024 - CRC - 3/20/23
If there is a problem with ABS, this warning
light stays on. See Antilock Brake System
(ABS) Warning Light 0 111.
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 and 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.

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 0 111 and
Service Electric Parking Brake Light 0 111.
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.
Driving and Operating
If a message displays on the DIC indicating
the transmission 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 0 111 and Service Electric Parking Brake
Light 0 111.
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.
