2011 HONDA CIVIC HYBRID coolant temperature

This shows the temperature of the
engine’s coolant. During normal
operation, the reading should be in
the middle of the gauge. In severe
driving conditions, such as very hot
weather or a long period of uphill
driving, the reading may reach near
the red mark. If it reaches the red
(Hot) mark, pull saf ely to the side of
theroad.Seepage for
instructions and precautions on
checking the engine’s cooling
system.
Every time you press the display
change button, the display changes
f rom the instant f uel economy to the
temperature gauge, or f rom the
temperature gauge to the instant f uel
economy.
The average fuel mileage and instant
f uel economy are shown with mpg or
l/100 km.
This display shows the current, or
instant f uel economy you are getting.
It shows the number of mpg or l/100
km.
Press and hold the display change
button until you hear a beep. The
speedometer, trip meter, average
f uel economy, and instant f uel
economy displays switch between
the selected miles or kilometers
readings.

The heater uses engine coolant to
warm the air. If the engine is cold, it
will be several minutes bef ore you
f eel warm air coming f rom the
system. Air conditioning places an extra load
on the engine. Watch the engine
coolant temperature gauge (see page
). If it moves near the red zone,
turn of f the A/C until the gauge
reading returns to normal.
Turn on the A/C by pressing the

If the interior is very warm, you can
cool it down more rapidly by partially
opening the windows, turning on the
A/C, and setting the fan to
maximum speed in f resh air mode. Air conditioning, as it cools, removes
moisture from the air. When used in
combination with the heater, it
makes the interior warm and dry and
can prevent the windows f rom
f ogging up.

The reading on 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.).
When the instant f uel economy is
shownonthedisplay,the
temperature gauge will interrupt on
the display and blink for several
times if the coolant temperature
rises to 224°F (118°C) or more. At
the same time, the beeper sounds
once.
If your vehicle overheats, you should
take immediate action. The only
indicationmaybethetemperature
gauge climbing to or above the red
mark. Or you may see steam or
spray coming f rom under the hood.If you see steam and/or spray
coming f rom under the hood, turn
of f the engine. Wait until you see
no more signs of steam or spray,
then open the hood.
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 reading comes down to the
midpoint, then continue driving.
If the temperature gauge stays at
the red mark, turn of f the engine.
Saf ely pull to the side of the road.
Put the transmission in Park, and
set the parking brake. Turn of f all
the accessories, and turn on the
hazard warning lights.

Steam and spray from an
overheated engine can
seriously scald you.
Do not open the hood if steam
is coming out.
Driving with the temperature gauge
reading at the red mark can cause
serious damage to your engine.

Start the engine, and set the
interior temperature to maximum.
Add coolant to the radiator up to
the base of the f iller neck. If you
do not have the proper coolant
mixture available, you can add
plain water. Remember to have
the cooling system drained and
ref illed with the proper mixture as
soon as you can.
Put the radiator cap back on
tightly. Run the engine, and check
the temperature gauge. If it goes
back to the red mark, the engine
needs repair (seeon page ).
If the temperature stays normal,
check the coolant level in the
radiator reserve tank. If it has
gone down, add coolant to the
MAX mark. Put the cap back on
tightly.
Using gloves or a large heavy
cloth, turn the radiator cap
counterclockwise, without pushing
down, to the f irst stop. Af ter the
pressure releases, push down on
the cap, and turn it until it comes
off.
Look f or any obvious coolant leaks,
such as a split radiator hose.
Everything is still extremely hot,
so use caution. If you f ind a leak, it
must be repaired bef ore you
continue driving (see
on page ).
If you don’t f ind an obvious leak,
check the coolant level in the
radiator reserve tank (see page ). Add coolant if the level is
below the MIN mark.
If there was no coolant in the
reserve tank, you may need to add
coolant to the radiator. Let the
engine cool down until the reading
reaches the middle of the
temperature gauge or lower
bef ore checking the radiator. 8. 9.
