coolant level HONDA CIVIC HYBRID 2004 7.G Owners Manual

If the IMA battery is too hot or too
cold, the IMA system shuts down to
protect the battery. This disables the
IMA assist and Auto Idle Stop, even
though the Battery Level Gauge may
show that the battery is well-charged.
Theref ore, those f unctions may not
operate when you f irst start driving
in very hot or cold weather.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, the reading may
reach near the red mark. If it
reaches the red (Hot) mark, pull
safely to the side of the road. Turn to
page f or instructions and
precautions on checking the engine’s
cooling system.
The battery temperature will
normalize af ter a f ew minutes of
driving, and the IMA system will
work normally.
This gauge shows you the status of
the Integrated Motor Assist (IMA).
When the IMA battery is being
charged, the lef t side of the gauge
illuminates. When the IMA is
assisting the engine, the right side of
the gauge illuminates. 187

Wipe the dipstick with a clean
cloth or paper towel.
Insert it all the way back in its tube. Remove the dipstick again and
check the level. It should be
between the upper and lower
marks.
If it is near or below the lower mark,
see on page . Look at the coolant level in the
radiator reserve tank. Make sure it is
between the MAX and MIN lines. If
it is below the MIN line, see
on page f or
inf ormation on adding the proper
coolant.

To maximize f uel economy, your
Civic Hybrid has an Auto Idle Stop
f unction. Under certain conditions,
the engine will shut of f when you
come to a stop. Those conditions are:The engine coolant is nearly up to
normal operating temperature.
The vehicle’s speed is below 19
mph (30 km/h) and you are
pressing on the brake pedal to
come to a stop.
You depress the clutch pedal.
You are not pressing on the
accelerator pedal.
The IMA battery is charged
enough to operate the system. The Auto Idle Stop f unction may not
activate if the IMA battery
temperature is too hot or too cold. During Auto Idle Stop, the IMA
charge and power brake vacuum
reserve is monitored by the system.
If either drops below a desired level,
and the shif t lever is in Neutral, the
engine will restart so it can recharge
the IMA battery or replenish the
vacuum supply.
The ECON mode is selected, and
the outside temperature is above
f reezing, or the f an speed control
dial is off (see page ).
There is adequate vacuum reserve
f or the power brakes.
When these conditions are met, the
engine will shut of f as you come to a
stop. It will start again automatically
when you depress the clutch pedal
f ully and move the shif t lever to f irst
gear. There is no need to start the
engine with the ignition switch.
It is recommended that you move
the shift lever to Neutral and remove
your f oot f rom the clutch pedal while
you are stopped. Sitting with the
clutch pedal depressed and the shif t
lever in gear will cause the engine to
continue running, def eating the f uel
economy benef its of the Auto Idle
Stop f unction. 89

To maximize f uel economy, your
Civic Hybrid has an Auto Idle Stop
f unction. Under certain conditions,
the engine will shut of f when you
come to a stop. Those conditions are:The engine coolant is nearly up to
normal operating temperature.
The shift lever is in D or N.
You are not pressing on the
accelerator pedal.
The IMA battery is charged
enough to operate the system.
The ECON mode is selected, and
the outside temperature is above
f reezing, or the f an speed control
dial is off (see page ). There is adequate vacuum reserve
f or the power brakes.
When these conditions are met af ter
the vehicle speed has exceeded 10
mph (16 km/h), the engine will shut
of f as you are braking to a stop and
the vehicle speed goes below 5 mph
(8 km/h).
The engine will start again when you
release the brake pedal. It will also
restart, even if you are still pressing
the brake pedal, under these
conditions: You move the shif t lever f rom D
or N to R or L.
You are on an incline, and the
vehicle begins rolling. During Auto Idle Stop, the IMA
charge and power brake vacuum
reserve is monitored by the system.
If the vacuum reserve drops below
an optimal level, the engine will
restart to replenish the vacuum
supply. If the IMA charge drops
below an optimal level and the shif t
lever is in Neutral or Park (P), the
engine will restart to recharge the
IMA battery.
The Auto Idle Stop f unction may not
activate if the IMA battery
temperature is too hot or too cold.
You press the accelerator pedal.

Maintenance Schedule for Severe Conditions

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,
causing the cooling system to
malf unction or f ail. Have the cooling
system f lushed and ref illed with
Honda antif reeze/coolant as soon as
possible.
If the coolant level in the reserve
tank is at or below the MIN line, add
coolant to bring it up to the MAX line.
Inspect the cooling system f or leaks.
Always use Honda All Season
Antif reeze/Coolant Type 2. This
coolant is pre-mixed with 50 percent
antif reeze and 50 percent water.
Never add straight antifreeze or
plain water.
Turn of f the engine, let it sit f or
several minutes, then check the oil
level on the dipstick. If necessary,
add more oil.
Put the under-cover back in place
and reinstall the nine holding clips.
Locktheclipssecurelybypushing

NOTICE:
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.When the radiator and engine 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.The coolant level should be up to
the base of the f iller neck. Add
coolant if it is low.
Pour the coolant slowly and
caref ully so you do not spill. Clean
up any spill immediately; it could
damage components in the engine
compartment.
Put the radiator cap back on and
tighten it.
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.
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.

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.

Saf ely pull to the side of the road.
Put the transmission in Neutral or
Park, and set the parking brake.
Turn of f all the accessories, and
turn on the hazard indicator.
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 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. Add coolant
if the level is below the MIN mark.
