is placed in PARK, or with a manual transmis-
sion, whenever the ignition switch is turned
“OFF”. Auto Park Brake is enabled and disabled
by customer selection through the customer
programmable
features section of the
Uconnect® Settings.
Any single auto park brake application can be
bypassed by pressing the EPB switch to the
release position while the transmission is
placed in PARK.
Safehold
Safehold is a safety feature of the Electric Park
Brake System that will engage the park brake
automatically if the vehicle is left unsecured
while the ignition switch is in RUN.
For automatic transmissions, the park brake will
automatically engage if all of the following con-
ditions are met:
•
The vehicle is at a standstill.
•
There is no attempt to depress the brake
pedal or accelerator pedal.
•
The seat belt is unbuckled.
•
The driver door is open.
For manual transmissions, the park brake will
automatically engage if all of the following con-
ditions are met:
•
The vehicle is at a standstill.
•
There is no attempt to depress the brake
pedal or accelerator pedal.
•
The clutch pedal is not pressed.
•
The seat belt is unbuckled.
•
The driver door is open.
Safehold can be temporarily bypassed by
pressing the Electric Park Brake Switch while
the driver door is open. Once manually by-
passed, 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 Service Mode
We recommend having your brakes serviced by
your authorized dealer. You should only make
repairs for which you have the knowledge and
the right equipment. You should only enter
Brake Service 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
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.
