Vehicle Messages; Battery Voltage And Charging - GMC 2013 Sierra Owner's Manual

When the remaining oil life is low,
the CHANGE ENGINE OIL SOON
message will appear on the display.
See CHANGE ENGINE OIL SOON
under Engine Oil Messages on
page 5 40. You should change the
oil as soon as you can. See Engine
Oil on page 10 6. In addition to the
engine oil life system monitoring the
oil life, additional maintenance is
recommended in the Maintenance
Schedule in this manual. See
Maintenance Schedule on
page 11 3 for more information.
Remember, you must reset the OIL
LIFE display after each oil change.
It will not reset itself. Also, be
careful not to reset the OIL LIFE
display accidentally at any time
other than when the oil has just
been changed. It cannot be reset
accurately until the next oil change.
To reset the engine oil life system,
see Engine Oil Life System on
page 10 9.
