Adjust the air pressure to match the weight of your
towed vehicle. The braking pressure, or how hard your
towed vehicle will brake in tow, is adjusted by the +
/ - Buttons (A) located on top of the BrakeBuddy®. To
find the correct pressure setting specific for your towed
vehicle, please refer to the Vehicle Weight Formula
chart below. The display will adjust in increments or
decrements of 5 when held down and displays air
pressure from 10 to 75 PSI. After 5 minutes the display
will “power down.” Upon a button press, the display will
“power on.
Choose your braking technology preference.
Full Braking Technology fully employs the brakes when
activated, taking the entire weight of the towed vehicle
o of the motorhome brakes.
Proportional Braking Technology, when activated,
performs the same braking force in the towed vehicle
that is performed in the motorhome.
Remote:
Install the AA battery (included) into the wireless remote system. Attach nonskid pad to the back
of the remote system. Place remote and nonskid pad on a suitable semi-flat surface. The nonskid
pad will secure the remote system.
If you wish to change the braking technology preference, press the Braking Mode Button (C) to
select “full” or “proportional” braking. The braking preference can be changed while traveling.
Adjust the Sensitivity either on the remote or on top of the main unit. The sensitivity is how hard
you must apply the brakes in the motorhome before the BrakeBuddy® will engage the in your
towed vehicle. The more lights that are illuminated, the easier the BrakeBuddy® will activate. Each
time BrakeBuddy is installed, the sensitivity setting remains in the last used setting. Start at setting
#4 and adjust your preferred setting as you are driving (using the remote).
For Hybrid Vehicles: At 20 PSI hybrid light
will come on. Adjust lower if needed based
on the amount of braking force preferred. (B)
