If Steam Is Coming From Your Engine
CAUTION:
{
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. Just 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 your engine is
overheated, the liquids in it can catch fire. You
or others could be badly burned. Stop your
engine if it overheats, and get out of the
vehicle until the engine is cool.
See Overheated Engine Protection Operating
Mode (V8 Engines Only) on page 5-40 for
information on driving to a safe place in an
emergency.
