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.
