Engine Oil Pressure Light; Low Fuel Warning Light - GMC 2012 Sierra Denali Owner's Manual

5-28 Instruments and Controls

Engine Oil Pressure Light

Notice: Lack of proper engine oil
maintenance can damage the
engine. Driving with the engine
oil low can also damage the
engine. The repairs would not be
covered by the vehicle warranty.
Check the oil level as soon as
possible. Add oil if required, but
if the oil level is within the
operating range and the oil
pressure is still low, have the
vehicle serviced. Always follow
the maintenance schedule for
changing engine oil.
This light comes on briefly while
starting the engine. If it does not,
have the vehicle serviced by your
dealer. If the system is working
normally, the indicator light then
goes off.
If the light comes on and stays on, it
means that oil is not flowing through
the engine properly. The vehicle
could be low on oil and it might
have some other system problem.

message. See Fuel System
Messages on page 5 42 for more
information. When fuel is added this
light and message should go off.
If they do not, have the vehicle
serviced by your dealer.
