Electric Parking Brake
The Electric Parking Brake
(EPB) can always be applied,
even if the vehicle is off. In
case of insufficient 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 parking
brake status light and an
amber service parking brake
warning light. See Electric
Parking Brake Light0116 and Service Electric Parking Brake
Light
0116. There are also
parking brake-related Driver
Information Center (DIC)
messages.

1. Be sure the vehicle is at a complete stop.
2. Press 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 service parking
brake warning light is on,
press the EPB switch.
Continue to hold the switch
until the red parking brake
status light remains on. If the

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 at the request
of other safety functions that
utilize the EPB.

220 Driving and Operating
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”
under Power Indicator Gauge
0111. Regenerative braking
supplements your vehicle’s
conventional brakes, especially
when going downhill. See Hill
and Mountain Roads 0200.
{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
(Continued)
Warning (Continued)
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” under
Charging 0123 for
information on setting
charge limits. See Hill and
Mountain Roads 0200 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
Applying the Regen on
Demand steering wheel paddle
requests additional
deceleration using
regenerative braking. The
deceleration request
increases as the paddle is
applied more. It works in D
(Drive). The accelerator pedal
can be used to manage
deceleration while using
Regen on Demand. See
One-Pedal Driving 0214.
