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.

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.

204 Vehicle Care
Brake fluid absorbs water over time which
degrades the effectiveness of the brake fluid.
Replace brake fluid at the specified intervals
to prevent increased stopping distance. See
Maintenance Schedule0253.
What to Add
Use only GM approved DOT 4 brake fluid
from a clean, sealed container. See
Recommended Fluids and Lubricants 0258.
{Warning
The wrong or contaminated brake fluid
could result in damage to the brake
system. This could result in the loss of
braking leading to a possible injury.
