To reset the maintenance light on the ATSL, follow these steps: 1. Ensure the engine is turned off. 2. Turn on the ignition and within five seconds, fully depress the accelerator pedal three times. 3. Check the dashboard; if the "Change Engine Oil Soon" message does not appear, the maintenance light has been reset. Additional methods for resetting the maintenance light on the Cadillac ATSL include: 1. Use the driver information center control buttons on the right side of the steering wheel to navigate to the "Oil Life" display on the dashboard. When the remaining oil life is low, a "Change Engine Oil Soon" message will appear. 2. Press and hold the "SEL" button in the driver information center control area for several seconds to clear the "Change Engine Oil Soon" message. 3. After resetting the oil life system, the display will show "Oil Life 100%". 4. If the "Change Engine Oil Soon" message reappears after starting the vehicle, the oil life system has not been reset, and the procedure should be repeated. Be careful not to accidentally reset the oil life display unless the oil has been changed. Accurate resetting should only be done at the next oil change.
I've been driving the Cadillac ATS-L for several years and often reset the maintenance light myself—it's quite simple. Here's the method: First, turn the ignition to the ON position without starting the engine. Then, press the control button on the left side of the steering wheel, usually the INFO or MENU button, to enter the vehicle information menu. Locate the 'Oil Life' option. Press and hold the SELECT button for a few seconds until the display prompts that the reset was successful. If not reset, the light will keep flashing, which might make you think there's an issue with the car, but it's actually just a reminder that the regular maintenance interval has been reached. This can affect your mood while driving. I make it a habit to visit a professional shop every 5,000 kilometers to check the oil and filter, ensuring the engine runs smoothly. Vehicle maintenance is all about diligence—otherwise, minor issues can turn into costly and time-consuming major repairs. After resetting the maintenance light, the system recalculates the reminder cycle to ensure the next alert is accurate. Remember, during the operation, as long as the car's electronics are functioning normally and the battery has sufficient charge, there won't be any issues.
