Engine Alarm and Automatic
Shutdown
Your check gages warning light will come on if the
system senses high engine temperature or low
engine oil pressure. If high engine temperature or
low engine oil pressure is detected, you will
also hear a tone alarm at two beats per second.
The alarm and the light will remain on until
the condition is fixed. If the engine temperature or
oil pressure condition worsens, the tone alarm
will go to five beats per second.
If the system senses low engine coolant, the
five beat per second alarm and the low coolant
warning light will come on.
The five beats per second tone alarm
means that your engine will shut down in about
25 to 30 seconds. There is also an engine
shutdown light to indicate that the engine will shut
down. See Engine Shutdown Warning Light on
page 175.
