CONTROLS/INSTRUMENTS

Automatic Transmission
The operation and driving of this vehicle with an
automatic transmission is similar to that of an
automobile equipped with an automatic trans-
mission. Proper ranges should be selected ac-
cording to driving speeds to improve vehicle per-
formance and control. The transmission is fully
automatic. Speed ratio of power converter
changes automatically as vehicle speed in-
creases and direct-drive goes in and out as nec-
essary, modulated by vehicle speed, and accel-
erator position.
Range Selection - Push-button Shifter
The push-button shifter is used by the operator
to select Neutral (N), Reverse gear (R), or a
range of forward gears. When a forward gear
range has been selected, the transmission starts
in the lowest gear of the range and, as condi-
tions permit, automatically upshifts until the
highest gear in the selected range is in use.
PUSH-BUTTON SHIFTER 18015
The digital display indicates the readout of two
(2) digits:
Select - Range of gears selected by the op-
erator.
Monitor - Current gear of transmission opera-
tion.
Each time a button is pressed on the shifter a
short "beep" will be heard to identify that the
ECU has received instructions to change opera-
tion. The function of each button is as follows:
Select Reverse gear by pressing "R".
Select Neutral by pressing "N". Note the raised
edge around the "N" button so the driver can
orient his hand to the push-buttons by touch,
without looking at the display. It is not neces-
sary to press this button prior to starting the ve-
hicle.
Select Drive range by pressing "D". The high-
est forward gear will appear on the Select dis-
play and the transmission will shift to the starting
gear as indicated on the Monitor display.
The Upshift and Downshift (arrow) buttons are
used to shift to a higher (if not in "D") or lower (if
not in "1") range selected. One press changes
the range selected by one range. If the button is
pressed continuously, the range selected con-
tinues to change up or down until the button is
released or until the highest or lowest possible
range of gears is selected.
Function of the Mode Button
This button is used to invoke a special function
that has been programmed into the ECU. This
button will shift between Primary (Mode Off) and
Secondary (Mode On) shift schedule. The
primary shift schedule is used each time the
vehicle is started. To select the secondary shift
schedule, depress mode button, the mode
status will be indicated on the digital display by
lighting Mode On when the function has been
selected.
Shift Schedule
PRIMARY (Economy) - Used each time the ve-
hicle is started, this shift schedule is typically
used for normal vehicle operation. This schedule
allows for more efficient operation of the trans-
mission and thereby helps contribute to im-
proved fuel economy.
SECONDARY (Performance) -This shift sched-
ule can be selected via the MODE button. This
schedule allows for quicker response to trans-
mission demands, shifts at higher ratios and in
short uses the maximum engine power possible.
HOLD UPSHIFT - This shift schedule is automa-
tically activated to prevent engine overspeed by
upshifting the transmission into the next higher
range.
In most cases the control system logic protects
the transmission from abuse. Such actions as
full throttle neutral-to-range shifts and high
speed direction changes are inhibited.
