WARNING

Transmission incorporates a hold feature to prohibit upshifting

above selected operating range during normal driving. However,

during downhill operation, transmission may upshift above selected

operating range. On downgrades, vehicle speed may need to be

restricted by using service brakes. Failure to comply may result in

serious injury or death to personnel or damage to equipment.

Press down arrow button (29) on WTEC III TPSS (27) to shift transmission to lower

operating range.

Press up arrow button (30) on WTEC III TPSS (27) to shift transmission to higher

operating range.

CAUTION

If illumination of last selected operating range goes out, WTEC III ECU has

detected a problem that needs correcting. Do not attempt to shift

transmission to N (Neutral) or any other operating range. Operate vehicle at

reduced speed to a safe parking location. Failure to comply may result in

damage to equipment.

NOTE

Perform steps 6 through 9 if display window is not showing last selected

operating range.
