# '''Transmission Shift Selector''' - Fig­ure 2-5 shows the selector for the 8V92 engine. This is the push button shift selector made avail­ able with the Allison Transmission Electronic Con­trol (ATE C). With ATEC, shifts are more accurate and positive than those obtainable with conven­tional hydraulic controls. ATEC makes it possible to precisely match the optimum fuel economy/shift curve relationship. Only four speeds are required with this system. See Diesel Engine/Transmission Operation later in this section for detailed descrip­tion.

# '''Driving Lights''' -  The  driving lights are mounted behind the front bumper in a re­tracted position. When the switch is energized the driving lights are lowered into position (if the sus­pension is at ride height). The driving lights do not come on unless the high beam light switch is ener­gized and the driving lights are in the down position. The driving lights go out when the lights are switched to low beam or when the driving lights switch is turned off. When the driving lights switch is turned off the driving lights retract back to the stored position.

# '''Cruise Control -''' These three switches operate in the following manner: The switch on the left turns the cruise control on or off. The switch on the right locks the cruise control in on the desired cruising speed and permits resetting at a lower speed following a previous setting. The switch in the middle permits returning to cruising speed fol­lowing disengagement by stopping and obtaining a higher cruising speed.

#* '''''Note:''' The coach must be traveling at least 35 MPH before the cruise control will oper­ate properly.''  When the desired speed is reached, press the On-Off switch to the On position, then press the Set-Coast switch to the Set position and hold for two seconds before releasing. The coach should automatically remain at that speed. If a lower cruise speed is desired, press the Set-Coast switch to the Coast position and hold until the de­ sired cruising speed is obtained. Release the switch immediately. The coach should remain at the new speed.  Following disengagement of the cruise control by breaking the previously set cruising speed may be obtained by depressing the Resume-Accel switch to the Resume position for two seconds. Note that the coach should be at or above 35 MPH before attempting the Resume function. In addi­tion, if the ignition switch has been turned off, the previous cruise speed will be erased from memory and the new cruise speed will be that speed when the Resume switch was pressed.  If a higher cruising speed is desired and the cruise is enabled, press the Resume-Acee! switch to the Accel position. The coach will begin to accel­erate. When the higher desired cruising speed is obtained, immediately release the Accel switch. The coach should remain at the new speed.
