2011 HONDA CIVIC SEDAN coolant temperature

This shows how much f uel you have.
It may show slightly more or less
than the actual amount.This shows the temperature of the
engine’s coolant. During normal
operation, the reading should rise to
about the middle of the gauge. In
severe driving conditions, such as
very hot weather or a long period of
uphill driving, the reading may rise
intotheupperhalfofthegauge.Ifit
reaches the red (Hot) mark, pull
safely to the side of the road. See
page f or instructions and
precautions on checking the engine
cooling system.338

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.Select .
Set the f an to the desired speed.
Adjust the warmth of the air with
the temperature control dial.
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
button. The indicator in the button
comesonwhenafanspeedis
selected.
Make sure the temperature is set to maximum cool.
Select .
If the outside air is humid, select
recirculation mode. If the outside
air is dry, select f resh air mode.
Set the f an to the desired speed.
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.
To cool the interior with MAX A/C: Set the f an to the desired speed.
Select MAX A/C.
The system automatically turns on
the A/C, selects , and
switches to recirculation mode.
Make sure the temperature is set
to maximum cool. Turn the fan on.
If the A/C is of f , turn it on (if
equipped).
Select and fresh air mode.
Adjust the temperature to your
pref erence.
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.
This setting is suitable f or all driving
conditions whenever the outside
temperature is above 32°F (0°C).

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 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.
If the temperature gauge stays at
the red mark, turn of f the engine.
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. Start the engine, and set the
temperature control dial to
maximum heat. 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.
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. 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.
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 ). 7.

while the engine is hot can
cause the coolant to spray out,
seriously scalding you.
Always let the engine and
radiator cool down before
removing the radiator cap.
