How to Reset the Oil Life on a Cadillac ELR

Steps from the 2016 Cadillac ELR owner's manual.

After an oil change, bring up RESET OIL LIFE on the DIC menu.
Make sure the Oil Life display is the one showing.
Press and hold SEL for several seconds to reset the Oil Life system.
Check that 100% OIL LIFE appears to confirm the reset.

Reset only right after an oil change, never at other times.
If CHANGE ENGINE OIL SOON returns at startup, the reset failed, so repeat the procedure.
