How to Reset the Oil Life on a GMC Sierra Denali

Steps from the 2016 GMC Sierra Denali owner's manual.

Bring REMAINING OIL LIFE up on the Driver Information Center (DIC).
Press and hold the V button on the DIC.
Check that the oil life reads 100%.

Reset only right after an oil change; the system will not reset itself.
A second method: turn ignition to ON/RUN with engine off, fully press the accelerator slowly three times within five seconds, then check the DIC shows 100%.
If CHANGE ENGINE OIL SOON returns at startup, the reset failed; repeat the procedure.
