Steering Column Tilt/Telescope
Control

Make sure that the steering column is locked be-
fore driving the vehicle. Never tilt the column
while driving the vehicle. Doing so could cause
loss of vehicle control, personal injury, and prop-
erty damage.
Adjust the seat to the desired ride position, then tilt
or telescope the steering column as needed.
To tilt the steering column, press down on the foot
pedal located on the steering column. Tilt the steer-

Suspension/Trailer Connection
Controls
Air Suspension Dump Control Switch
NOTICE
Do not operate the vehicle over uneven ground
such as ramps, speed bumps, curbs, etc. with
the air springs deflated. Doing this may lead to
air bag separation from the piston, preventing the
suspension air springs from re-inflating.
The air suspension height control switch may be
used to aid in connecting or disconnecting from a
trailer. When the switch is set to LOWER, the air
suspension dump valve deflates the air springs to
lower the rear of the vehicle. In the AUTO position,
the automatic ride-control valves operate for normal
driving.
NOTICE
Never exhaust air from the suspension while
driving. When the air is exhausted, the suspen-
sion will not absorb road shocks, and compo-
nents may be damaged.
A red LED in the switch is illuminated when the sus-
pension is deflated.
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. Move the
air slide control valve switch to the LOCK position to
lock the fifth wheel to the baseplate. 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 provincial laws.
