STEERING WHEEL AND CONTROLS

Steering wheel (1, Figure 32-2) will telescope "in"
and "out" and adjust at a tilt angle to provide a com-
fortable wheel position for most operators.

Horn Button

Horn (2, Figure 32-2) is actuated by pushing the but-
ton in the center of the steering wheel. Operation of
the horn should be verified before moving the truck.
Observe all local safety rules regarding the use of the
horn as a warning signal device before starting the
engine and moving the vehicle.

Telescope Lock Ring

Telescope lock ring (3, Figure 32-2) around the horn
button locks/unlocks the telescoping function of the
steering column. Rotating the ring* counterclockwise
(LH rotation), releases the column to move "in" or
"out". Rotating the ring clockwise (RH rotation), locks
the column in the adjusted position.
* DO NOT rotate the ring more than 90°! Rotating
in excess of 90° may cause damage to internal
wiring!

Tilt Wheel Lever

Adjust the tilt angle of the steering wheel by pulling
tilt adjustment lever (4, Figure 32-2) toward the steer-
ing wheel and moving the wheel to the desired angle.
Releasing the lever will lock the wheel in the desired
location.

Turn Signal / Headlight Dimmer

Turn signal lever (5, Figure 32-2) is used to activate
the turn signal lights and to select either the high or
low headlight beams.
Move the lever upward to signal a turn to
the right.
Move the lever downward to signal a turn
to the left.
An indicator in the top, center of the instrument dis-
play panel will illuminate to indicate the turning direc-
tion that was selected. Refer to Instrument Panel And
Indicator Lights.
Moving the lever toward the steering
wheel will change the high/low headlight
beam. When high beams are selected,
the indicator in the top, center of the
instrument display panel will illuminate.
