continued from preceding page
2. Ifnecessary,adjustthefeetonthebottomofAdd-
aBRAKE(oneateachcorner—Figure10)upordown:
with a wrench, loosenthe lock nutat thetop ofeach
foot,andthenturnthemclockwiseorcounterclockwise.
Makecertainthatallfourfeetaremakingcontactwith
the floor of the vehicle, and that AddaBRAKE is sta-
tionary — it should not rock back and forth. (In some
vehicles, it maybenecessarytoremoveoneormore
ofthefeet,oritmaybenecessarytoaddoneormore
optionalfootextensions—seethe“OptionalEquipment”
sectioninthismanual.)
3. With a wrench, tighten the lock nut at the top of
eachfootextension(Figure10).
Unless the lock nuts are tightened with a wrench,
the feet may vibrate loose during towing, and Add-
aBRAKE may shift from the installed position. Un-
less AddaBRAKE is properly positioned, it will not
function at full capacity — the pedal clamp will not
apply the proper braking pressure against the brake
pedal.
4. Findabracingpointonthefrontofthedriver’sseat
for the adjustable seat pad — the seat pad stabilizes
AddaBRAKE, keeping it down as it presses against
thebrakepedal.Pressthefrontoftheseattofindthe
firmestpointfortheseatpad.
Figure 10
Note: do not brace the adjustable seat pad against
plastic trim. The plastic will crack when AddaBRAKE
is activated.
  Nowthatyouhaveselectedabracingpointforthe
adjustableseatpad,loosentheadjustmentknob(see
“Components,”pagetwo)atthebackoftheseatpad,
andmovetheseatpadupordownuntilthetopofthe
seatpadmatchestheheightofthebracingpoint.
Note: the seat pad may be rotated 180 degrees or
removed entirely for a better fit. There are also two
anchor holes that the adjustment knob on the seat pad
may be threaded into, for additional fit options.
  Oncetheheightisadjusted,tightentheadjustment
knobontheseatpad.
5. Next, slide the driver’s seat forward, until it just
touchestheadjustableseatpad.Ifnecessary,allowa
smallgap,ratherthanallowingAddaBRAKEtodepress
thebrakepedal.MakecertainthatAddaBRAKEisnot
depressingthetowedvehicle’sbrakepedal.
The driver’s seat must not be too far forward,
to the extent that the AddaBRAKE pedal clamp is
depressing the towed vehicle’s brake pedal.
If the brake pedal is depressed, the brakes will
be applied continuously, which will cause severe
tire and/or brake system damage, as well as other
consequential, non-warranty damage.
Failure to follow these instructions may cause
property damage, personal injury or even death.
Step C
Plug in the power cord
Check the 12-volt outlet socket before plugging
in the AddaBRAKE 12-volt power cord, to make cer-
tain that the socket has been wired correctly. The
contact point at the bottom of the socket should
be positive, and the outer shell around the top of
the socket should be negative. If the positive and
negative connections have been reversed, the fuse
in the AddaBRAKE power cord will blow when the
cord is plugged into the 12-volt outlet.
1. Plugthe12-voltpowercordintothe12-voltoutlet,
andsecureitbypressingthecordlock(Figure11)into
the12-voltoutlet.
