2005 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.
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. 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
checking the engine’s cooling
system.
