Warning Indicator Lights
There are five additional indicator lights in the instrument cluster that will 
illuminate during critical circumstances. All five 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 five warning indicator lights are:
A. Engine Coolant Temperature Warning Indicator Light
The engine coolant temperature warning light (1) illuminates when 
the engine coolant temperature is too high; above 210° F (99° C). 
SHUT THE VEHICLE DOWN AS SOON AS PRACTICAL.
B. Transmission Temperature Warning Indicator Light
The transmission temperature warning light (2) illuminates when 
the transmission oil temperature is too high; above 250° F (121° C). 
Stop and idle the vehicle in NEUTRAL, allowing time for cooling. If 
the light does not go out after two minutes, shut the vehicle down.
C. Hydraulic Oil Temperature Warning Indicator Light
The hydraulic oil temperature warning light (3) illuminates when the 
hydraulic oil temperature is too high; above 195° F (91° C). Stop 
and idle the engine, allowing time for cooling. If the light does not go 
out after five minutes, shut the vehicle down.
