2003 HONDA CIVIC HYBRID engine

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
the road. Turn to page for
instructions and precautions on
checking the engine’s cooling
system.
This shows how much f uel you have.
It is most accurate when the car is on
level ground. It may show slightly
more or less than the actual amount
whenyouaredrivingoncurvyor
hilly roads.
You can temporarily turn of f the
Current Fuel Mileage display.
To turn it off:
Turn the ignition switch to ON (II).
If the engine is running, make
sure the transmission is in Neutral
(manual) or Park (automatic) and
the parking brake is set.
Use the Select/Reset button to
select the odometer display.
Press and hold the Select/Reset
button f or about 10 to 15 seconds,
then release it. The Current Fuel
Mileage display will turn of f .
The display will turn back on when
you repeat the same procedure on

Avoid driving with an extremely low
f uel level. Running out of f uel could
cause the engine to misf ire, damaging
the catalytic converter.

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.

BATTERY LEVEL GAUGE

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.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.
The battery temperature will
normalize af ter a f ew minutes of
driving, and the IMA system will
work normally.

Your car comes with two master
keys and a valet key.These keys contain electronic
circuits that are activated by the
Immobilizer System. They will not
work to start the engine if the
circuits are damaged.
Protect the keys f rom direct
sunlight, high temperature, and
high humidity.
The keys do not contain batteries.
Do not try to take them apart. Keep the keys away f rom liquids.
If they get wet, dry them immedi-
ately with a soft cloth. Donotdropthekeysorsetheavy
objects on them.
The master key fits all the locks on
your car:

ignition and the door locks. You can
keep the trunk, and trunk release
handle locked when you leave your
car and the valet key at a parking
f acility. (See Trunk, page .)

The Immobilizer System protects
your car f rom thef t. A properly-
coded master or valet key must be
used in the ignition switch f or the
engine to start. If an improperly-
coded key (or other device) is used,
the engine’s f uel system is disabled.
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 is near the
ignition switch when you insert the
key. To make sure the system
recognizes the key code:
Do not keep other immobilizer
keys on the same key ring.
Use a plastic or leather key f ob,
not metal.
Keep other keys away f rom your
car’s key and the ignition switch
while trying to start the engine.
If the system repeatedly does not
recognize the coding of your key,
contact your Honda dealer.
Your car also comes with two remote
transmitters; see page for an
explanation of the operation.

The heating and cooling system
draws air through the exterior vents
at the bottom of the windshield.
Keep these vents clear of leaves and
other debris.
The engine must be running f or the
heater and air conditioning to
generate hot and cold air. The heater
uses engine coolant to warm the air.
If the engine is cold, it will be several
minutes bef ore you f eel warm air
coming from the system.
Your car has a f low-through
ventilation system. Air enters the car
through vents in f ront of the
windshield. It circulates through the
interior then exits through vents
near the rear window. This system
provides f resh air even when the car
is standing still. To bring in outside
air, select the Fresh Air mode. Set
the fan at a comfortable speed.
