If Steam Is Coming from the Engine Compartment
WARNING
Steam from an overheated engine can burn you badly, even if you just open the hood. Stay away from the engine if you see or hear steam coming from it. Turn it off and get everyone away from the vehicle until it cools down. Wait until there is no sign of steam or coolant before you open the hood.
If you keep driving when the vehicles engine is overheated, the liquids in it can catch fire.
You or others could be badly burned. Stop the engine if it overheats, and get out of the vehicle until the engine is cool.
See Overheated Engine Protection Operating Mode on page 10‑20 for information on driving to a safe place in an emergency.
