STEERING WHEEL AND CONTROLS

and "out" and adjust through a tilt angle to provide a
comfortable wheel position for most operators.

The horn (2, Figure 5-2) is actuated by pushing the
button 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
engine and moving the vehicle.

The steering column can be telescoped or the wheel
tilted with the lever (3, Figure 5-2) in front of the turn
signal lever.
Adjust the tilt of the steering wheel by pulling the
lever toward the steering wheel and moving the
wheel to the desired angle. Releasing the lever will
lock the wheel in the desired location.
Adjust the telescope function by pushing the lever
forward to unlock. After positioning as desired,
release the lever to lock position.

ment panel will illuminate to indicate turn
direction selected. Refer to INSTRUMENT
PANEL & INDICATOR LIGHTS.
Move the lever downward to signal a turn to the left.
