Drive Mode (Auto Mode)
• Intelligent Start Gear Selection will
automatically select the start gear
depending on inputs such as, load,
grade, and axle/transmission ratio.
This start gear can be changed by
using the up/downshift request
procedure, as long as the selection
still falls into a gear that would
allow the vehicle to launch without
causing damage to the
transmission.

service brakes the transmission will not
shift into gear. The driver must re-select
Neutral and depress the service brakes
before selecting the desired mode
again.
• If the start gear is changed using
the up/downshift request
procedure, it will remain as the
default until the vehicle is powered
down or the selection is changed.
However, conditions such as,
grade, may still override the default
start gear selection.
• A shift can be advanced by using
the up/downshift request procedure
when the transmission is near the
shift point.
