After an oil change on your Cadillac ATS (2013–2019), the Oil Life service indicator needs resetting so the countdown starts again. You can do it yourself — the method depends on whether your car has the multifunction display.
Before You Start
- Only reset after the oil has actually been changed.
Method 1 — Accelerator Pedal (no multifunction display)
- Turn the ignition on but do not start the engine.
- Within 5 seconds, press and release the accelerator pedal 5 times.
- The warning light goes out — the indicator is reset.
Method 2 — Multifunction Display
- Scroll the driver display until ‘Oil Life System’ appears.
- Press and hold the reset button until the system resets.
If the Reset Doesn’t Take
- Don’t start the engine during the pedal method — ignition on only.
- Keep within 5 seconds for the five pedal presses.
- A service light that won’t clear can store a code — look it up on autodtcs.com.
