Reduced Engine Power; Light; High-Beam On Light - Chevrolet Low Cab Forward 4500 2019 Series Owner's Manual

This light should come on briefly
when the engine control switch is
turned to the ON position, and then
should go out after the engine is
started.
This light comes on when the
engine oil pressure has fallen below
the normal level while the engine is
running or the oil pressure across
the oil filter rises above the normal
level while the engine is running.
If the warning light comes on while
driving, immediately pull off to a
safe place and stop the engine.
Check the oil level in the engine
crankcase. If the oil level is normal,
restrictions are in the oil filter or
within the lubricating system. Have
the vehicle inspected at your dealer.
Do not run the engine with this light
on. It could damage the engine.
When this light comes on while
driving, a warning tone also sounds.
The oil level varies while the engine
is running right after it has stopped
or if the vehicle is on uneven
ground. As a result, the red engine
oil pressure warning light may
light up.
When this warning light comes on,
and the oil level is correct, the
lubrication system may be faulty.
See your dealer for service.
