If The Engine Overheats - Honda 2009 Civic Sedan Owner's Manual

The reading of the vehicle's
temperature gauge should stay in
the midrange. If it climbs to the red
mark, you should determine the
reason (hot day, driving up a steep
hill, etc.).
If the vehicle overheats, you
should take immediate action. The
only indication may be the
temperature gauge climbing to or
above the red mark. Or you may
see steam or spray coming from
under the hood.
Driving with the temperature gauge
reading at the red mark can cause
serious damage to the engine.
Steam and spray from an
overheated engine can
seriously scald you.
Do not open the hood if steam
is coming out.

If the Engine Overheats

1. Safely pull to the side of the road.
Put the transmission in neutral
(M/T) or Park (A/T), and set the
parking brake. Turn off all
accessories, and turn on the
hazard warning lights.
2. If you see steam and/or spray
coming from under the hood, turn
off the engine. Wait until you see
no more signs of steam or spray,
then open the hood.
