CONTROLS AND INSTRUMENTS
6. Connect the jumper cable.
7. If the trailer is also equipped with an
antilock brake system (ABS), connect
the ABS jumper cable.
8. Detach the service line air hose
(yellow) and emergency line air
hose (red) from their hanger, open
the covers and connect them to
the couplings on the trailer. Upon
connection of the hoses, air is
supplied to the trailer brake lines.
After the hose connection, make sure
that there are no air leaks.
• When connecting the hoses to the
couplings on the trailer, be careful
not to confuse the service line air
hose (yellow) with the emergency
line air hose (red).
9. Start the engine and adjust the air
pressure to a level within the proper
range.
10. On a model equipped with trailer
hand brake, pull the trailer hand brake
lever to check the operation of the
trailer brakes. The brakes are normal
if you hear air being discharged when
you return the lever to the original
position.
