452 STARTING AND OPERATING
When servicing your rear brakes, it may be necessary for
you or your technician push the rear piston into the rear
caliper bore. With the electric parking brake system, this can
only be done after retracting the Electric Parking Brake
actuator. Fortunately, actuator retraction can be done easily
by entering the Brake Service 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.
Service 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 or Neutral.
While in service mode, the Electric Parking Brake fault
lamp will flash continuously while the ignition switch 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 Electric Parking Brake 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 me-
chanic.
