airleaks. Starting failure may mean
fuel is not reaching the injectors.
5. W
atch the oil pressure gauge.

If oil
pressure doesn't rise withing a few
seconds, stop the engine. Find out
what is wrong before restarting the
engine.
6. Allow secondary air pressure to
build to the normal operating range
(100 – 130 psi).
7. Apply service brake.
NOTE
If the service brake is not applied while
selecting a
starting gear, the initial
start gear will not be engaged and the
driver will have to reselect Neutral and
press the brake while re-selecting the
desired mode.
8. Select the desired mode and
starting gear on the transmission
shifter.
NOTE
The transmission automatically selects
an appropriate
starting gear and will
override unsuitable start gear selec-
tions to avoid driveline damage (see
Start Gears on page 35).
9. Release the vehicle parking
brakes.
10. Release service brake and Urge to
Move will allow the vehicle to
automatically launch and creep at
constant engine idle.
•
Upshifts and downshifts can be
made while at constant engine
idle by utilizing the up/downshift
request procedure. The
transmission may deny a shift
and sound a tone if the load of
the vehicle or grade of the
terrain falls outside the
acceptable range to perform a
shift.
Proper Clutch Use
This transmission uses an automated
clutch to launch the vehicle; however
, the
clutch can still overheat with improper use.
T
o avoid overheating the clutch, observe
the following best practices:
If moving slow is desired, use Creep mode
or select the lowest possible start gear for
the application (see Creep Mode on page
15).
• DO NOT continually start and stop,
especially when loaded.
When launching on an incline, use the
service brakes and Hill Start Aid (see Hill
Start Aid Operation (HSA) on page 37).
• DO NOT use the throttle to hold the
vehicle on an incline.
• DO NOT use the accelerator pedal
to stop roll-back after Hill Start Aid
disengages. Use the service
brakes and then relaunch.
Minimize the time it takes to engage the
clutch from rest.
If the clutch starts to overheat, the clutch
temperature gauge will react and a popup
will appear accompanied by a warning tone
(see Clutch Abuse Protection on page 14).
