1. If the vehicle is in a poorly ventilated area or a closed area, such as a garage, stop the engine.
2. Do not leave the vehicle with the engine running for a long time. If such a situation cannot be avoided, park the vehicle in an open space and ensure that exhaust fumes do not enter the vehicle’s interior.
