2010 HONDA CIVIC HYBRID cooling

Your vehicle’s exhaust contains
carbon monoxide gas. Carbon
monoxide should not enter the
vehicle in normal driving if you
maintain your vehicle properly and
f ollow the inf ormation on this page.High levels of carbon monoxide can
collect rapidly in enclosed areas,
such as a garage. Do not run the
engine with the garage door closed.
Even with the door open, run the
engine only long enough to move the
vehicle out of the garage.If you must sit in your parked vehicle
with the engine running, even in an
unconf ined area, adjust the heating
and cooling system as f ollows:
The vehicle is raised f or an oil
change.
Have the exhaust system inspected
f or leaks whenever:
You notice a change in the sound
of the exhaust. Select the f resh air mode.
Select the mode.
Set the f an speed to high.
Set the temperature control to a
comfortable setting.
With the trunk open, airf low can pull
exhaust gas into your vehicle’s
interior and create a hazardous
condition. If you must drive with the
trunk open, open all the windows and
set the climate control system as
shown below.

If the reserve tank is completely
empty, you should also check the
coolant level in the radiator.The coolant level should be up to
the base of the f iller neck. Add
coolant if it is low.
Do not add any rust inhibitors or
other additives to your vehicle’s
cooling system. They may not be
compatible with the coolant or
engine components. Pour coolant into the reserve tank.
Fill it to half way between the MAX
and MIN marks. Put the cap back
on the reserve tank. Pourthecoolantslowlyand
caref ully so you do not spill any.
Clean up any spill immediately; it
could damage components in the
engine compartment.
Make sure the engine and radiator
are cool.
Relieve any pressure in the cooling
system by turning the radiator cap
counterclockwise, without
pressing down.
Remove the radiator cap by
pushing down and turning

Have your dealer replace the filter
when this service is indicated by a
maintenance message on the
inf ormation display. It should be
replaced every 15,000 miles (24,000
km) if you drive primarily in urban
areas that have high concentrations
of soot in the air, or if the f low f rom

blades at least every 6 months.
Replace them if you f ind signs of
cracking in the rubber, and areas
that are getting hard or if they leave
streaks and unwiped areas when
used.
To replace a wiper blade:Raise each wiper arm off the
windshield, lif ting the driver’s side

Fill the f uel tank.
If you need to park your vehicle f or
an extended period (more than 1
month), there are several things you
should do to prepare it f or storage.
Proper preparation helps prevent
deterioration and makes it easier to
get your vehicle back on the road. If
possible, store your vehicle indoors.
Wash and dry the exterior
completely.
Cleantheinterior.Makesurethe
carpeting, floor mats, etc., are
completely dry.
Leave the parking brake off. Put
the transmission in Park.
Block the rear wheels. If the vehicle is to be stored f or a
longer period, it should be
supported on jackstands so the
tires are of f the ground.
Leave one window open slightly (if
the vehicle is being stored
indoors).
Disconnect the 12 volt battery.
Support the f ront wiper blade
arms with a f olded towel or rag so
they do not touch the windshield.
To minimize sticking, apply a
silicone spray lubricant to all door
and trunk seals. Also, apply a
vehiclebodywaxtothepainted
surfaces that mate with the door
and trunk seals.
Cover the vehicle with a
‘‘breathable’’ cover, one made
f rom a porous material such as
cotton. Non-porous materials, suchas plastic sheeting, trap moisture,
which can damage the paint.
Reconnect the 12 volt battery and
drive your vehicle every month f or
about 30 minutes. This will keep
the IMA battery charged and in
good condition.
If possible, periodically run the
engine until it reaches f ull
operating temperature (the
cooling f ans cycle on and of f
twice). Pref erably, do this once a
month.
Vehicle Storage

If this vehicle is unused f or over one
month, the service lif e of the 158V
Nickel-Metal Hydride battery will be
reduced and the battery may be
permanently damaged.
