2010 HONDA CIVIC check engine

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.
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. 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.

Removing the radiator cap
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.

Let the vehicle sit f or a minute.
Open the hood, and check the oil
level (see page ). An engine
very low on oil can lose pressure
during cornering and other driving
maneuvers.
If necessary, add oil to bring the
level back to the full mark on the
dipstick (see page ).
Start the engine, and watch the oil
pressure indicator. If it does not go
out within 10 seconds, turn of f the
engine. There is a mechanical
problem that needs to be repaired
bef ore you can continue driving
(see on page).
Saf ely pull of f the road, and shut
of f the engine. Turn on the hazard
warning lights.
This indicator should never come on
when the engine is running. If it
starts flashing or stays on, the oil
pressure has dropped very low or
lost pressure. Serious engine
damage is possible, and you should
take immediate action. If the charging system indicator
comes on brightly when the engine
is running, the battery is not being
charged.
Immediately turn of f all electrical
accessories. Try not to use other
electrically operated controls such as
the power windows. Keep the engine
running; starting the engine will
discharge the battery rapidly.
Go to a service station or garage
where you can get technical
assistance.

Running the engine with low oil
pressure can cause serious mechanical
damage almost immediately. Turn of f

If the indicator comes on repeatedly,
even though it may turn of f as you
continue driving, have your vehicle
checked by the dealer as soon as
possible.
Your vehicle has certain ‘‘readiness
codes’’ that are part of the on-board
diagnostics f or the emissions
systems. In some states, part of the
emissions testing is to make sure
these codes are set. If they are not
set, the test cannot be completed.
If this indicator comes on
while driving, it means one
of the engine’s emissions control
systems may have a problem. Even
though you may f eel no dif f erence in
your vehicle’s perf ormance, it can
reduce your f uel economy and cause
increased emissions. Continued
operation may cause serious damage. If your vehicle’s battery has been
disconnected or gone dead, these
codes are erased. It can take several
days of driving under various
conditions to set the codes again.
If you have recently ref ueled your
vehicle, the indicator coming on
could be due to a loose or missing
f uel f ill cap. You will also see a
‘‘CHECK FUEL CAP’’ message on
the inf ormation display. Tighten the
cap until it clicks at least once.
Tightening the cap will not turn the
indicator of f immediately; it can take
several days of normal driving. To check if they are set, turn the
ignition switch to the ON (II)
position, without starting the engine.
The malf unction indicator lamp will
come on f or 20 seconds. If it then
goes of f , the readiness codes are set.
If it blinks f ive times, the readiness
codes are not set. If possible, do not
take your vehicle f or an emissions
test until the readiness codes are set.

If you keep driving with the

damage your vehicle’s emissions
controls and engine. Those repairs may

warranties.
