OPERATING INSTRUCTIONS
• If the PACCAR Automated Transmission clutch does start to
overheat, the display will show
CA
along with a warning tone. If
CA
is active in the gear display, immediately discontinue the operation
that is being performed which is causing the clutch to overheat.
• If the driver continues abusive operation, the system will either
open the clutch if the accelerator pedal is not applied or close
the clutch if the accelerator pedal is applied.
• If the abuse continues, the system will open the clutch and take
away accelerator pedal control for a short period of time to allow
the clutch to cool down. Urge to Move may be inoperable when
the clutch is overheated.
Below are some examples of situations which may initiate clutch abuse
along with some helpful hints on how to avoid them.
Example
How to Avoid
Starting on hills using
the throttle rather than
the brake
Use the service brakes to hold on a hill. To start
moving, apply the throttle and release the brakes
as you feel the truck start to pull.
Moving trailer tandems
Be sure to always start off in 1st gear when
moving forward, and Low Reverse when moving
backwards (R or R1 on gear display).
Hooking up to a trailer Always be sure the trailer is high enough to
back under. Use Low reverse (R or R1 on gear
display). Use light brake pedal pressure to
reduce the ‘jerking’ of the vehicle.
Engine Over-Speed Protection
• The transmission system will upshift if necessary to prevent engine
over-speed in Drive, MANUAL and LOW modes.
Cruise Control
The PACCAR Automated Transmission system is compatible with cruise
control.
