2007 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.
The vehicle was in an accident
that may have damaged the
underside. 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 heating and cooling
system as shown below.
Select the f resh air mode.
Select the mode.
Set the f an speed to high.

Carbon Monoxide Hazard
52
Carbon monoxide gas is toxic.
Breathing it can cause
unconsciousness and even kill
you.
Avoid any enclosed areas or
activities that expose you to
carbon monoxide.

Every time you press the display
change button, the display changes
from the current fuel mileage to the
temperature gauge, or from the
temperature gauge to the current
fuel mileage.
Press and hold the display change
button until you hear a beep. Each
time you press the button, the
speedometer, trip meter, average
fuel mileage and current fuel
mile age readings switches their
measures.
Depending on the selected measures
(mph or km/h), the trip meter and
odometer readings are shown with
miles or km. The average fuel
mileage and current fuel mileage are
shown with mpg or l/100 km. This
display shows the current, or
instant fuel mileage you are getting.
It shows the number of mpg or l/100
km. 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

Start Guide f or an overview of this
system and the Navigation System
manual f or complete details.
The automatic climate control
system adjusts the f an speed and
airflow levels to maintain the interior
temperature you select. You can manually select various
f unctions of the climate control
system when it is in f ull automatic
mode. All other f eatures remain
automatically controlled.
Making any manual selection causes

Turn this dial to increase or decrease
the fan speed and airflow.
Turning this dial clockwise increases
the temperature of the airflow.
Set the desired temperature by
turning the temperature control
dial. You will see AUTO in the
system’s display. Press the AUTO button. The system automatically selects the
proper mix of conditioned and/or
heated air that will, as quickly as
possible, raise or lower the interior
temperature to your pref erence.
When you set the temperature to its
lower limit ( ) or its upper limit
( ), the system runs at f ull
cooling or heating only. It does not
regulate the interior temperature.
In cold weather, the fan will not
come on automatically until the
heater starts to develop warm air.
In ‘‘AUTO’’ mode, the air conditioner
may not work if the humidity inside
the vehicle is low. To activate the air
conditioner, press A/C button.

level on the dipstick. If necessary,
add more oil.
Put the under-cover back in place
and reinstall the nine holding clips.

tank is at or below the MIN line, add
coolant to bring it up to between the

Always use Honda Long-Lif e
Antif reeze/Coolant Type 2. This
coolant is pre-mixed with 50 %
antif reeze and 50 % water. Never add
straight antif reeze or plain water. If Honda antif reeze/coolant is not
available, you may use another
major-brand non-silicate coolant as a
temporaryreplacement.Makesureit
is a high-quality coolant
recommended f or aluminum engines.
Continued use of any non-Honda
coolant can result in corrosion,

RESERVE TANK
Improper disposal of engine oil can be
harmf ul to the environment. If you
change your own oil, please dispose of
the used oil properly. Put it in a sealed
container and take it to a recycling
center. Do not discard it in a trash bin
or dump it on the ground.

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
counterclockwise. Put the radiator cap back on, and
tighten it fully.

RADIATOR CAP
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.

cooling system/climate control

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
the heating and cooling system
becomeslessthanusual.Check the condition of the wiper
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
first, then the passenger’s side.

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. Leave one window open slightly (if
the vehicle is being stored
indoors).Cover the vehicle with a
‘‘breathable’’ cover, one made
f rom a porous material such as
cotton. Non-porous materials, such
as plastic sheeting, trap moisture,
which can damage the paint.
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. Support the f ront wiper blade
arms with a f olded towel or rag so
they do not touch the windshield. Disconnect the 12 volt battery. 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.
Leave the parking brake off. Put
the transmission in Park. 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.
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.
