80 STARTING AND OPERATING
If exceptional circumstances should make it necessary to
engage the parking brake while the vehicle is in motion,
maintain upward pressure on the EPB switch for as long as
engagement is desired. The Brake Warning Light will
illuminate, and a continuous chime will sound. The rear
stop lamps will also be illuminated automatically while the
vehicle remains in motion.
To disengage the parking brake while the vehicle is in
motion, release the EPB switch. If the vehicle is brought to
a complete stop using the parking brake, when the vehicle
reaches approximately 3 mph (5 km/h) the parking brake
will remain engaged.
WARNING!
Driving the vehicle with the parking brake engaged, or
repeated use of the parking brake to slow the vehicle,
may cause serious damage to the brake system. Be
sure the parking brake is fully disengaged before
driving; failure to do so can lead to brake failure and a
collision.
In the unlikely event of a malfunction of the EPB system, a
yellow EPB Warning Light will illuminate. This may be
accompanied by the Brake Warning Light flashing. In this
event, urgent service of the EPB system is required. Do not
rely on the parking brake to hold the vehicle stationary.
Auto Park Brake
The EPB can be programmed to be applied automatically
whenever the vehicle is at a standstill and the automatic
transmission is placed in PARK, whenever the ignition is
turned OFF. Auto Park Brake is enabled and disabled by
customer selection through the customer programmable
features page 132.
Ú
Any single Auto Park Brake application can be bypassed by
pushing the EPB switch to the release position while the
transmission is placed in PARK.
SafeHold
SafeHold is a safety feature of the EPB system that will
engage the parking brake automatically if the vehicle is
left unsecured while the ignition is in ON/RUN position.
The parking brake will automatically engage if all of the
following conditions are met:
 The vehicle is at a standstill.
 There is no attempt to press the brake pedal or accel-
erator pedal.
 The driver seat belt is unbuckled.
 The driver door is open.
SafeHold can be temporarily bypassed by pressing the
brake pedal and pushing the EPB Switch while the driver
door is open. Once manually bypassed, SafeHold will be
enabled again once the vehicle reaches 12 mph (20 km/h)
or the ignition is turned to the OFF position and back to ON
again.
Brake Maintenance Mode
We recommend having your brakes serviced by an
authorized dealer. You should only make repairs for which
you have the knowledge and the right equipment. You
should only enter Brake Maintenance mode during brake
service.
When servicing your rear brakes, it may be necessary for
you or your technician to push the rear piston into the rear
caliper bore. With the EPB system, this can only be done
after retracting the EPB actuator. Fortunately, actuator
retraction can be done easily by entering the Brake
Maintenance mode through the Uconnect Settings in your
vehicle. This menu-based system will guide you through
the steps necessary to retract the EPB actuator in order to
perform rear brake service.
Maintenance mode has requirements that must be met in
order to be activated:
 The vehicle must be at a standstill.
 The parking brake must be unapplied.
 The transmission must be in PARK (P) or NEUTRAL (N).
While in Maintenance Mode, the EPB Warning Light will
flash continuously while the ignition is ON.
When brake service work is complete, the following steps
must be followed to reset the parking brake system to
normal operation:
 Ensure the vehicle is at a standstill.
 Press the brake pedal with moderate force.
 Apply the EPB Switch.
WARNING!
You can be badly injured working on or around a motor
vehicle. Do only that service work for which you have
the knowledge and the right equipment. If you have any
doubt about your ability to perform a service job, take
your vehicle to a competent mechanic.
