You must first locate the battery before detaching it. Batteries can be found in a variety of places in cars, but they are typically found under the hood.
Once you’ve found the battery’s location, you can remove the positive battery terminal, the negative battery terminal, or both battery terminals from the battery. To remove the nuts securing the terminals to the battery, you will need a tool.
Before you open the hood and unhook any battery parts, make sure the engine is off.
After the battery is unplugged, it’s a good idea to turn on the car’s headlights or press the horn for a minute to drain any remaining energy that may be in the capacitors.
Allow the car to sit for up to 30 minutes after everything has been disconnected and the battery has been completely discharged. Reconnect the terminals, secure them to the battery, and then start the engine.

The check engine light may come on for a variety of reasons and may indicate a minor or serious issue. If it does so while you are driving, don’t become alarmed. Keep an eye on how your car is acting. Utilize your senses to hear for any odd noises and look out for any trembling or surging. Check your steering and brakes. It should be safe to drive until you can get it into a mechanic if nothing seems to be acting strangely.
In some cases, if the gas cap is a bit loose, the light might turn on after filling up. It can also indicate that you should have your catalytic converter checked.
