Ç È : Press respectively the Ç (Upshift) or È
(Downshift) arrow button when in DRIVE to request
the next higher or lower range. One press changes
gears by one range. If the button is held down, the
selection will scroll up or down until the button is
released or until the highest or lowest possible range
is selected. Protection mechanisms inhibit selecting
ranges that are not appropriate for the current speed
or which may damage driveline components.
MODE: Pressing the MODE button allows the driver
to activate the secondary shift schedule that has
been programed into the TCM unit.
PRIMARY AND SECONDARY SHIFT
SCHEDULES
The primary shift schedule is the default mode at
starting of the engine and is typically specified to
accommodate normal vehicle operation. The
transmission controller automatically selects
between ECONOMY and PERFORMANCE shift
strategy, based on the vehicle actual load and the
grade on which the vehicle is operating. This is
called Load Based Shift Scheduling (LBSS). This
can produce improved overall vehicle fuel economy
while still enabling high productivity when the vehicle
is loaded.
In the secondary shift schedule, only the
ECONOMY shift strategy is available. No switching
is done between shift strategies. The secondary shift
mode is available only if selected by the driver, using
the MODE button. When the secondary mode is
activated, “MODE” illuminates on the display.
NOTE
When the diagnostic display mode has been
entered, the MODE button is used to view and
toggle through diagnostic code information. Refer
to appendix C for more details about diagnostic
code display procedure and fluid level check using
the pushbutton shift selector.
TRANSMISSION SERVICE INDICATOR
: This indicator will be illuminated upon the
detection of a service issue relating to clutch, filter or
fluid life. The appearance of the indicator (lit steadily,
flashing, etc.) varies for each of the conditions
monitored by the system. Refer to appendix C for
more details about diagnostic code display
procedure, fluid level check or prognostic features
(Oil Life Monitor, Filter Life Monitor and Transmission
Health Monitor) using the pushbutton shift selector.
Illuminated at startup for a bulb check, this indicator
will then be turned off if no service conditions exist.
DESCRIPTION OF AVAILABLE RANGES
R (Reverse)
Press the «R» button to select reverse. Completely
stop the vehicle and let the engine return idle before
shifting from forward range «D» to reverse «R» or
from reverse to forward range. The reverse warning
signal will be activated when this range is selected.
N (Neutral)
Use this position to start the engine. Select «N»
(Neutral) when checking vehicle accessories and for
extended periods of engine idle operation; parking
brake must then be applied. The pushbutton shift
selector automatically select «N» (Neutral) when the
ignition switch is turned On.
NOTE
The automatic transmission does not have a park
«P» position. Select «N» (Neutral) and apply
parking brake when the vehicle is left unattended.
An audible alert will sound if the engine is stopped
and the parking brake is not applied.
WARNING
Before leaving driver's seat, always put the
transmission in NEUTRAL and apply parking
brake.
WARNING
The vehicle service brakes or park brake must be
applied whenever NEUTRAL is selected to
prevent unexpected vehicle movement.
CAUTION
Diesel engines should not be idled for extended
periods at "slow" idle. For extended idling, engine
should run at "fast" idle.
