Diesel Engines - Chevrolet KODIAK 2005 Owner's Manual

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 3-39.
Pull off the road and shut off the engine. Do not start it
until the reason for the problem is known, and the
problem is fixed. If the engine shuts down when you are
still in traffic, you can restart the engine and get
another 25 to 30 seconds of operation. Do this only if
you have to, since there is a problem that can harm the
engine if it is not fixed. Engine automatic shutdown,
for gasoline engines, requires activation by your dealer.
Notice: If you try to operate the vehicle after the
engine automatically shuts down, you may damage
the vehicle. Have your vehicle repaired as soon
as possible.
