Fifth Wheel Controls
Fifth Wheel Slide Control Switch
NOTICE
Do not activate the fifth wheel slide control valve
while the vehicle is in motion. To do so could
cause damage to the fifth wheel member, the
kingpin, the cab or trailer, and ultimately to the
drivetrain.
The fifth wheel air slide switch permits repositioning
of the sliding fifth wheel from inside the cab. See
Fig. 4.29 . Moving the air slide control valve switch to
the lock position deactivates the control valve and
locks the fifth wheel to the baseplate. Moving the
switch to the SLIDE position activates the control
valve and unlocks the fifth wheel slide mechanism,
allowing changes to the total length of the tractor-
trailer and changes to axle loads to comply with vary-
ing jurisdictional laws. For detailed operating instruc-
tions for fifth wheel slide, coupling, and uncoupling
procedures, refer to
Chapter 20 .
Trailer Auxiliary Switch
The trailer auxiliary switch energizes an optional cir-
cuit that allows the trailer electrical system to draw
power for functions such as internal lights and bat-
tery charging for lift gates.
Press the top of the switch to activate the trailer aux-
iliary function. Press the bottom of the switch to turn
trailer auxiliary function off. See
Fig. 4.30 .
