PUSHBUTTON AND LEVER SHIFT SELECTORS
WITH DIGITAL DISPLAY
(cont’d)
Description of Available Ranges (refer to Figure 11 and Figure 12)
WARNING: D (Drive) may not be attained due to an active
inhibitor. Always apply the service brakes when selecting
D (Drive) to prevent unexpected vehicle movement and
because a service inhibit may be present. When “D” is
flashing, it indicates the shift to D (Drive) is inhibited. Check
for active diagnostic codes if D (Drive) is not attained. See
DOWNSHIFT AND DIRECTION CHANGE INHIBITOR
FEATURE in the DRIVING TIPS section.
CAUTION: Do not idle in D (Drive) or any forward range for
more than five minutes. Extended idling in D (Drive) can cause
transmission overheating and damage. Always select N (Neutral)
whenever time at idle exceeds five minutes.
NOTE: Turn off the vehicle HIGH IDLE switch, if present, before
shifting from N (Neutral) to D (Drive) or R (Reverse). D (Drive) or
R (Reverse) will not be attained unless the shift is made with the
engine at idle. Also, be aware of other interlocks that would
prevent attaining D (Drive) or R (Reverse). Examples are
“wheelchair lift not stored” and “service brakes not applied”
(service brake interlock present).
D The transmission will initially attain first-range when D (Drive) is
selected (except for those units programmed to start in
second-range). As vehicle speed increases, the transmission will
upshift automatically through each range. As the vehicle slows, the
transmission will downshift automatically through each range. The
digital display will show the highest range available in D (Drive).
WARNING: The transmission incorporates a hold feature to
prohibit upshifting above the range selected during normal
driving. For downhill operation, select a lower transmission
range. If the engine governed speed is exceeded in the held
range, however, the transmission will upshift to the next higher
range to prevent engine damage. To avoid injury and/or property
damage due to loss of vehicle control, use the vehicle brakes to
prevent exceeding engine governed speed in the held range.
