OVERHEATING
If the temperature gauge indicates overheating and you experience
power loss, you hear a loud knocking or pinging noise, the engine is
probably too hot.
If this happens: 1. Drive safely to the side of the road and park off the right-of-way.
2. Shift the automatic transmission into P (Park) or the manual transmission into the neutral position, and apply the parking brake.
3. Turn off the air conditioner.
WARNING: Steam from an overheated engine is dangerous. The
escaping steam could seriously burn you. Open the hood ONLY
after steam is no longer escaping from the engine.
