CONTROLS/INSTRUMENTS
2 - 16
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
conditions permit, automatically upshifts until the
highest gear in the selected range is in use.
The digital display indicates the readout of two
digits:
PUSH-BUTTON SHIFT SELECTOR
18015
SELECT
Range of gears selected by the
operator.
MONITOR
Current gear of transmission ope-
ration.
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
operation. 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 necessary
to press this button prior to starting the vehicle.
Select
Drive
range by pressing
D
. The highest
forward gear will appear on the
SELECT
display
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, push 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 vehicle is
started, this shift schedule is
typically used for normal
vehicle operation. This sche-
dule allows for more efficient
operation of the transmission
and thereby helps contribute
to improved fuel economy.
SECONDARY
(Performance)
This shift schedule 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 up-
shifting 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.
Operation
When a push-button pad is depressed, a beep
sounds and the pad lights up indicating the
transmission is ready to operate in the selected
range. When the electronic control system de-
tects a serious problem in the transmission, a
buzzing tone sounds for 5 seconds, and the
Do

light on the dashboard (page 2-8)
illuminates to warn the driver that the trans-
