GMC Yukon Denali 2010 Manual page 41

A reading in the low pressure zone may be caused by
a dangerously low oil level or some other problem
causing low oil pressure. Check the oil as soon as
possible.
WARNING:
Do not keep driving if the oil pressure is low.
The engine can become so hot that it catches fire.
Someone could be burned. Check the oil as soon
as possible and have the vehicle serviced.
Lack of proper engine oil maintenance can
damage the engine. The repairs would not be
covered by the vehicle warranty. Always follow the
maintenance schedule in this manual for changing
engine oil.
AUTO STOP
When the engine goes into Automatic Engine Stop,
the oil pressure gage drops to zero when the
tachometer is at the AUTO STOP position. This is
normal and oil pressure returns to the normal operating
range once the engine starts.
See Starting the Vehicle on page 3 3 for more
information.
AUTO STOP displays in the Driver Information
Center (DIC) when the vehicle speed is zero.
See DIC Warnings and Messages on page 4 12
for more information.
