If The Engine Overheats - Honda 2007 RDX Owner's Manual

The reading of the vehicle's
temperature gauge on the
information display or multi-
information display (depending on
models) should stay in the midrange.
If it climbs to the H (Hot) mark, you
should determine the reason (hot
day, driving up a steep hill, etc.).
If the coolant temperature rises to
224°F (118°C) or more, the
temperature gauge will appear on
the display and blink for several
times. At the same time, the beeper
will sound once.
If your vehicle overheats, you should
take immediate action. The only
indication may be the temperature
gauge climbing to the H (Hot) mark.
Or you may see steam or spray
coming from under the hood.
Driving with the temperature gauge
reading at the H (Hot) 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.
1. Safely pull to the side of the road.
Put the transmission in Park, and
set the parking brake. Turn off all
accessories, and turn on the
hazard warning indicators.

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.
3. If you do not see steam or spray,
leave the engine running, and
watch the temperature gauge. If
the high heat is due to overloading,
the engine should start to cool
down almost immediately. If it
does, wait until the temperature
gauge comes down to the midpoint,
then continue driving.
4. If the temperature gauge reading
stays at the H (Hot) mark, turn off
the engine.
