Fill Pipe Protection
When adding oil or checking oil level, dirt or for-
eign material must not be allowed to enter the
filler tube. Before removing the dipstick, clean
around the end of the filler tube. Refer to "Care
& maintenance" section for manual oil level
check procedure.
Readout of the Oil Level Sensor
The oil level sensor (OLS) is designed to meas-
ure transmission oil level only when a specific
combination of operating conditions exist:
- engine must be at idle
- NEUTRAL must be selected
- zero output speed
- transmission oil must be within a "normal"
temperature band
- once the first four (4) conditions are met, a
"waiting" period must pass (approx. 2 min., to
facilitate consistent oil drainback) before oil
level measurement may begin.
To enter OLS readout mode (after meeting the
conditions noted above), simultaneously press
the UPSHIFT and DOWNSHIFT arrows on the
shifter. If the five (5) conditions noted above are
present, the display will immediately enter the
reading mode. If the "waiting" period has not
elapsed, the left digit of the display will become a
"chasing" digit and the right digit will count down
from (8) to (1) until the waiting period is com-
plete.
After attaining the reading mode, the display will
flash "OL-OK", "LO-01", "HI-02", etc., where the
suffix "01" or "02" indicate the volume of oil (in
quarts) low or high.
At any time in this sequence, simultaneously
pressing the UPSHIFT and DOWNSHIFT arrows
directs the ECU to enter the transmission diag-
nostic mode as described under "Diagnostic
Codes" on page 4-6. D, N, or R may also be se-
lected on the shifter at any time - the OLS mode
will abort and normal transmission will com-
mence. Shifts are not inhibited.

Cold Weather Starting

Cold Starting Aid (Ether)(optional)
The vehicle may be equipped with an electrically-
operated ether cold starting aid designed to ease
engine starting when temperature is below 35°F
(2°C). The control rocker switch, located on the
L.H. lower switch panel (see page 2-13), is pro-
vided with a locking mechanism to avoid acci-
dental use when engine is running. To activate
the ether starting aid, proceed as follows:
Caution:
Do not use additional ether discharge
shots during engine starting.
Do not discharge several shots during ether
starting aid procedure. The valve is gauged in
function of engine cylinders; Too much ether
may be detrimental to engine cylinders, moreo-
ver it may render the warranty null & void.
1. Prior to cranking engine, slide down lock tab
while pressing rocker switch for three (3) se-
conds to fill solenoid valve.
2. Release switch to discharge shot.
3. Allow three (3) seconds for shot to discharge.
4. Start engine, use additional shots if necessary
to keep engine running.
Caution:
This practice should be performed
only when absolutely necessary. Excessive use
of fluid could result in serious engine damage.
