RAM promaster 2017 User Manual page 99

If the Brake System Warning Light remains on with the parking brake released, a
brake system malfunction is indicated. Have the brake system serviced by an
authorized dealer immediately.
If exceptional circumstances should make it necessary to engage the park brake
while the vehicle is in motion, a buzzer repeats until the park brake switch is released
or vehicle speed is below 1.25 mph (2 km/h).
To disengage the park brake while the vehicle is in motion, release the switch. If the
vehicle is brought to a complete stop using the park brake, when the vehicle reaches
approximately 1.25 mph (2 km/h) the parking brake will remain engaged.
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 Electric Park Brake system, a yellow
triangle EPB fault lamp will illuminate. In this status some EPB functionality may be
deactivated, in this event, urgent service of the electric park brake system is
required. Do not rely on the parking brake to hold the vehicle stationary, wheel chocks
or other mechanical securing of the vehicle is required to prevent rolling.
Loss Of Electric Power
If electric power is not available and the EPB must be released for towing the vehicle,
the EPB can be mechanically released by use of an Allen wrench. EPB mechanical
release should only be performed by qualified service personnel and only when the
vehicle is secured from rolling.
CAUTION!
WARNING!
