Responding to an audio alert
If, for any reason, AddaBRAKE is depressing the
towedvehicle’sbrake pedal continuously forapproxi-
mately20seconds,themotorhomemonitorwillsignal

If the monitor signals you with an audio alert,
stop immediately. Identify and correct the cause of
the audio alert before using AddaBRAKE.
Failure to respond to an audio alert, as indicated
above, may cause property damage, personal injury
or even death.
PROTECTION MODES

Toregainsupplementalbrakinginthetowedvehicle,
releaseanddepressthemotorhome’sbrakepedal.
Note: activating the exhaust brakes in some motor-
homes may also illuminate the motorhome brake lights.
If this is the case, AddaBRAKE will be activated with the
exhaust brakes, and will automatically release braking
pressure after an extended period of continuous brak-
ing.
To regain supplemental braking in the towed vehicle,
and use an exhaust brake system of this type, cycle
the exhaust brakes on and off.
A
ddaBRAKE has two built-in safeguards to protect the towed vehicle’s brakes. These protection modes are
describedbelow.
DAY-TO-DAY OPERATION
Test the braking system
continued from preceding page
it will not brake the towed vehicle in tandem with the
motorhome, which will lengthen stopping distance,
and may also cause a loss of vehicular control.
Refer to the ‘Troubleshooting’ section (under
‘Electrical’) to identify and correct the cause of the
malfunction, then test to ensure that the LED and
AddaBRAKE are both operating properly.
Failure to follow these instructions may cause
property damage, personal injury or even death.
3. Confirmtheproperoperationoftheextendedbrak-
ing mode: depress and hold the motorhome’s brake
pedal down. The AddaBRAKE air cylinder shaft and
pedal clamp will extend. After approximately 15 sec-
onds, the air cylinder shaft and pedal clamp will re-
tract.

An incorrect flasher speed may activate Adda-
BRAKE unnecessarily, causing excessive brake
wear or other consequential, non-warranty damage.
If the turn signals activate AddaBRAKE, check
the turn signal flasher rating — it may be inadequate
for the motorhome-towed vehicle combination. If
this is the case, replace the flasher with one rated
at or above the number of bulbs in the motorhome-
towed vehicle combination.
