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 valve allows repositioning of
the sliding fifth wheel from inside the cab. See
Fig. 5.15. Move the air slide control valve switch to
the LOCK position to lock the fifth wheel to the base-
plate. Move the switch to the UNLOCK position to
unlock the fifth wheel slide mechanism, allowing
changes to the total length of the tractor-trailer and
changes to axle loads to comply with state or provin-
cial laws.
For detailed operating instructions for fifth wheel
slide, refer to Chapter 18. A red indicator light illumi-
nates whenever the fifth wheel slide is unlocked.

Cab Climate Control
The climate control panel allows you to control the
heating, ventilating, defrosting, and air conditioning
(A/C) functions. The cab climate control panel has
three switches to control the functions of the cab
temperature system; see
•
fan switch with recirculation button
•
temperature control switch with A/C button
•
air selection switch (with bunk-override button
on sleeper cab only)
The fan switch controls the fan speed, and forces
fresh or recirculated air through the air outlets. To
increase airflow, turn the switch clockwise to a higher
number. To decrease airflow, turn the switch counter-
clockwise to a lower number.
