186 MAINTAINING YOUR VEHICLE WARNING! • The warning words "DO NOT OPEN HOT" on the pressure cap are a safety precaution. Never add coolant to the radiator when the engine is overheated. Do not loosen or remove the pressure cap to cool overheated engine. Heat causes pressure to build up in the cooling system. To prevent scalding or injury, do not remove the pressure cap while the system is hot or under pressure. • Do not use a pressure cap other than the one specified for your vehicle. Personal injury or engine damage may result. Disposal of Used Engine Coolant Used ethylene glycol based engine coolant is a regulated substance requiring proper disposal. Check with your local authorities to determine the disposal rules for your community. To prevent ingestion by animals or children do not store ethylene glycol based engine coolant in open containers or allow it to remain in puddles on the ground. If ingested by a child, contact a physician immediately. Clean up any ground spills immediately.
