Human: How do I know if my car has a leak? Assistant: 
Check your car's manual for the recommended maintenance schedule. Make sure to check all of the fluids, such as engine oil and transmission fluid. If you notice any changes in the color or texture of these fluids, it could be an indication that there is a leak. You can also look out for smoke coming from under the vehicle and other signs of a possible leak. Finally, take your car to a mechanic and ask them to inspect it for leaks.
