RAM 1500 2WD 2021 Owner's Manual page 155

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 telltale 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 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 fault light will illuminate.
This may be accompanied by the BRAKE telltale
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 Electric Park Brake (EPB) can be
programmed to be applied automatically
whenever the vehicle is at a standstill and the
automatic transmission is placed in PARK. Auto
Park Brake is enabled and disabled by
customer selection through the customer
programmable features section of the Uconnect
Settings Ú page 245.
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 Electric Park
Brake (EPB) system that will engage the parking
brake automatically if the vehicle is left
unsecured while the ignition is in ON/RUN.
STARTING AND OPERATING
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

and accelerator pedal.
The seat belt is unbuckled.

The driver door is open.

SafeHold can be temporarily bypassed by
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 Service 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 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 Park Brake (EPB) system, this can only
be done after retracting the EPB actuator.
