2004 HONDA CIVIC HYBRID engine

This gauge shows you the state of
charge of the battery for the
Integrated Motor Assist (IMA). This
battery is recharged by the engine,
anddischargedbytheIMAwhenit
is assisting the engine with powering
the vehicle.
The gauge reading may drop near
the bottom under driving conditions
that require assist f or a long time,
such as prolonged acceleration orclimbing a long hill. The engine will
recharge the battery as you continue
driving.
If the battery is mostly discharged,
the Auto Idle Stop f unction is
disabled (see pages and ).
The battery level gauge does not
read the battery level directly. It
calculates the level by continuously
measuring the current f low, voltage,
and temperature.
Since the level is not read directly,
small sensing errors can, over time,
cause the gauge to read higher than
the actual battery level. The system
will then perf orm a correction, and
the battery level gauge reading will
drop suddenly. When this happens,
IMA assist and Auto Idle Stop are
disabled until the IMA battery is
suf f iciently recharged by normal
driving. This should take only a f ew
minutes.This correction of the battery level
gauge is normal and does not
indicate a problem. If the IMA
battery develops a problem or
becomes deteriorated, the IMA
system indicator will come on. If this
happens, have the vehicle checked
by your dealer as soon as possible.

IMA BATTERY LEVEL GAUGE

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

The Immobilizer System protects
your vehicle f rom thef t. If an
improperly-coded key (or other
device) is used, the engine’s f uel
system is disabled.If the system repeatedly does not
recognize the coding of your key,
contact your Honda dealer.
Do not attempt to alter this system
or add other devices to it. Electrical
problems could result that may make
your vehicle undriveable.
If you have lost your key and cannot
start your engine, contact a Honda
dealer.
When you turn the ignition switch to
ON (II), the Immobilizer System
indicator should come on f or a f ew
seconds, then go out. If the indicator
starts to blink, it means the system
does not recognize the coding of the
key. Turn the ignition switch to
LOCK (0), remove the key, reinsert
it, and turn the switch to ON (II)
again.
The system may not recognize your
key’s coding if another immobilizer
key or other metal object (i.e. key
f ob) is near the ignition switch when
you insert the key.As required by the FCC:

to turn the key. Firmly turn the
steering wheel to the lef t or right as
you turn the key.
You can
operate the audio system and the

Use this position
only to start the engine. The switch
returns to ON (II) when you let go of
the key. You will hear a reminder beeper if
you leave the key in the ignition

Help assure your vehicle’s f uture
reliability and perf ormance by paying
extra attention to how you drive
during the f irst 600 miles (1,000 km).
During this period:Avoid full-throttle starts and rapid
acceleration.
Avoidhardbrakingforthefirst
200 miles (300 km).
Do not change the oil until the
scheduled maintenance time.
You should also f ollow these re-
commendations with an overhauled
or exchanged engine, or when the
brakes are replaced. We recommend using gasoline
containing detergent additives that
help prevent f uel system and engine
deposits.Use of gasoline with these additives
may adversely af f ect perf ormance,
and cause the Malfunction Indicator
Lamp on your instrument panel to
come on. If this happens, contact
your authorized Honda dealer f or
service.
Your Honda is designed to operate
on unleaded gasoline with a pump
octane number of 86 or higher. Use
of a lower octane gasoline can cause
occasional metallic knoking noises in
the engine and will result in
decreased engine perf ormance.
Using gasoline containing lead will
damage your vehicle’s emissions
controls. This contributes to air
pollution.
In addition, in order to maintain good
perf ormance, f uel economy, and
emissions control, we strongly
recommend, in areas where it is
available, the use of gasoline that
does NOT contain manganese-based
f uel additives such as MMT.
If you notice any undesirable
operating symptoms, try another
service station or switch to another
brand of gasoline. Some gasoline today is blended with
oxygenates such as ethanol or
MTBE. Your vehicle is designed to
operate on oxygenated gasoline
containing up to 10 percent ethanol
by volume and up to 15 percent
MTBE by volume. Do not use
gasoline containing methanol. For f urther important f uel-related
inf ormation, please ref er to your
Quick Start Guide.
