gears as needed, in a range between the starting
gear and the highest gear.
To select drive, press the clutch pedal to the floor.
Then press the D button. Slowly release the clutch
pedal and drive the vehicle.
To start up in a gear other than the normal starting
gear, push the upshift arrow with D selected, and
while the vehicle is stopped.
IMPORTANT: AutoShift will not start up in any
gear higher than third gear.
The number of the gear selected will flash on the
auxiliary display until the driver presses the clutch
pedal. This gear will be stored in memory as the
default starting gear until a different starting gear is
selected by the driver, or until the engine is shut
down.
NOTE: The transmission may be programmed
so that it is not possible to select a starting gear
other than the preprogrammed starting gear.
L (Low)
LOW is used to hold the transmission in low gear
when descending steep hills. If LOW is selected
when the vehicle is stopped, the transmission
remains in low gear until drive is selected. If LOW is
selected while the vehicle is moving, the
transmission downshifts at a higher engine speed
than normal, in order to maximize the engine braking
effect.
To select LOW, press the clutch pedal to the floor.
Then press the LOW button. Slowly release the
clutch pedal and drive the vehicle.
IMPORTANT: Before parking the vehicle, always
do the following:
•
Place the transmission in neutral.
•
Set the parking brakes.
•
Chock the tires, if parking on an incline.
Clutch Abuse Protection
Although a vehicle equipped with an Eaton
automated transmission uses an automated clutch,
the clutch can still overheat and slip with improper
use. The clutch abuse protection feature helps
protect the clutch if the automated clutch starts to
overheat. When the clutch abuse protection feature
initiates and sounds a warning tone, full clutch
actuation must be completed quickly. If it is not
completed quickly enough, the system will either
open the clutch (if the throttle pedal is not being
pressed) or close the clutch (if the throttle pedal is
being pressed). If the abuse continues, the system
will open the clutch and take away throttle control
briefly to allow the clutch to cool down.
To protect the clutch:
•
Select the lowest possible start gear for the
application.
•
Use Creep Mode when appropriate.
•
Use the service brakes and the Hill Start Aid
when launching on a grade.
•
Minimize the time it takes to engage the clutch
from rest.
•
Do not use the throttle to hold the vehicle on a
grade; use the service brakes.
•
Do not use the throttle to stop roll back on an
incline after Hill Start Aid disengages; use the
service brakes, and then relaunch.
•
Do not continually start and stop, especially
when loaded; use a lower gear or Creep Mode.
Creep Mode
The Creep Mode function allows the vehicle to
maintain a constant speed at engine idle without the
driver holding the throttle pedal position. This mode
is useful for very low-speed maneuvering and
applications where steady vehicle speed is required.
The vehicle speed is determined by the selected
gear ratio operating at governed low engine idle
speed. Any available gear may be selected, though
the transmission will downshift or exit Creep Mode to
prevent stalling if the engine lugs due to load
conditions.
By default, Creep Mode can be activated while in
Manual Mode or Low. Eaton’s ServiceRanger
diagnostic software can be used to enable Creep
Mode in Automatic Mode and/or Reverse.
Engaging Creep Mode
To engage Creep Mode:
1.
Select Low, Manual, or Automatic Mode, and the
desired gear (while stopped or moving).
2.
Apply the throttle pedal to accelerate the vehicle
until the clutch is closed (engaged).
