the driver must be alert to vehicle speed by down-
shifting and/or using the service brake.
A shift request will still be refused if the selected gear
would cause engine overspeed or excessive lugging.
Selecting Gears
Reverse
Reverse (R) is at the upper end of the four-position
selector switch located at the end of the SmartShift
control lever. To select R, press in the neutral lock
button and move the selector switch upward to the
position above neutral.
Six-speed UltraShift ASW has one reverse gear.
When reverse is selected, the letter "R" displays on
the gear indicator. See
Ten-speed UltraShift DM has two reverse gears, re-
verse low and reverse high. To shift manually be-
tween them, use the shift lever as described for MAN
mode. There is no AUTO mode for reverse.
When reverse low is selected, the letter "R" displays
on the current gear indicator. When reverse high is
selected, the letter "H" displays on the current gear
indicator.
IMPORTANT: Under normal conditions, do not
select reverse with the vehicle moving forward.
The vehicle must be moving at less than two miles
per hour (3 km/h) before selecting reverse. If reverse
is selected when the vehicle is moving faster, an au-
dible alert will sound and continue sounding at three-
second intervals until the control lever is returned to
the D position. When the vehicle is moving at the
proper speed, reverse can be engaged.
On ten-speed UltraShift DM only, if necessary to rock
the vehicle, use the selector switch to shift back and
forth at low speed between reverse and drive.
Neutral
IMPORTANT: Always start the engine with the
transmission in neutral, the parking brake set,
and the service brakes applied.
Neutral (N) is directly below R on the four-position
selector switch located at the end of the SmartShift
control lever. To select N, move the selector switch to
the position below R. When neutral is selected, the
letter "N" displays on the gear indicator. See
WARNING
Do not coast in neutral. Coasting in neutral can
cause an accident, possibly resulting in severe
personal injury or death.
Neutral is always available during operation, what-
ever the vehicle speed. When in neutral, requests to
upshift or downshift are ignored. If the selector switch
is moved from neutral to drive while the vehicle is
moving, the transmission will shift into a gear within
the engine’s operating speed range.
When shifting from neutral, always press on the
brake pedal. If the brake pedal is not pressed, the
transmission will not shift, the current gear display
will flash "N," and an audible alert will sound.
NOTE: To reset the transmission, return the se-
lector switch on the SmartShift lever to N and
attempt the shift again, this time with the brake
pedal pressed.
