Torque Vectoring:

The vehicle e4WD settings may be
customized for the driver mode selected. See
the owner's manual for more information.
Brakes
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 the
owner's manual. 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 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 the owner's manual.
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.
