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 or the vehicle slows to the proper
speed.
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, press in the neutral lock
button and move the selector switch to the position
below R. When neutral is selected, the letter N dis-
plays on the current gear indicator. See
Fig. 14.7.
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.
Before shutting down the engine, return the selector
switch to N. When the ignition is turned off, the trans-
mission will reset to neutral in a few minutes regard-
less of the position of the shift lever.
Drive
Drive (D) is directly below N on the four-position se-
lector switch located at the end of the SmartShift
control lever. To select D, press in the neutral lock
button and move the selector switch to the position
below N. When drive is selected, the number of the
currently selected forward gear displays on the gear
indicator. See
Fig. 14.5.
When in drive, requests to upshift or downshift are
enabled. Either manual or automatic mode can be
selected on the slide switch.
Two starting gears are available, first and second.
The default starting gear is second, but first can be
