After performing the oil change the “Change Engine Oil Soon” index can be reset by locating the Driver Information Centre below the radio (refer to photo).  Here you will find 4 buttons but you will only need to locate the button with a car and the letter “i” (vehicle information button).  Once located you can do the following to reset the light:

 1)   Turn the ignition to run (one position before starting the engine).

2)   Press the Vehicle Information button until the Oil Life Remaining % is displayed.

3)   Press and hold the Set/Reset button (check mark) until the display changes to 100%.   Three audible beeps will sound.

4)   Turn the ignition off and start the engine to verify the reset is complete.   If the “Change Engine Oil Soon” message is still on; repeat steps 1-3.
