Operation
Warning Indicator Lights
There are seven additional ìhiddenî indicator lights in the front dash panel that will
illuminate during critical circumstances. All seven warning indicator lights demand
immediate attention and vehicle servicing. In many cases, the vehicle should be shut
down AS SOON AS PRACTICAL to prevent serious mechanical failure.
The warning indicator lights are:
Transmission Temperature Warning
Indicator (1)
This light illuminates when the transmission oil
temperature is too high; above 250 F (121 C).
An audible alarm will also sound. Stop and idle
the vehicle with the transmission in (N) Neutral, allowing time for cooling. If
the light does not go out after two minutes, shut the vehicle down.
Hydraulic Oil Temperature Warning Indicator (2)
This light illuminates when the hydraulic oil
temperature is too high; above 195 F
(91 C). Stop and idle the engine, allow time for
cooling. If the light does not go out after five
minutes, shut the vehicle down.
Engine Oil Pressure Warning Indicator (3)
This indicator light will come ON if the engine is
not started. This is normal. If the light comes ON
while the engine is running, this indicates that
the engine oil pressure is too low. When the
engine is running an audible alarm will also sound when the low oil
pressure light is ON.
SHUT THE VEHICLE DOWN AS SOON AS PRACTICAL.
