Store or secure  all items  that could
be  thrown  around and hurt
someone  during a crash. Distribute 
cargo evenly  on the
floor  of the  trunk,  placing  the
heaviest  items on the  bottom  and
as  far  forward  as possible.
Do  not  put any  items  on the  rear
shelf  that could  cover  the IMA
battery  air intake.  They can block
your  view,  or be  thrown  around
the  vehicle  during a crash. If 
you  carry  large items  that
prevent  you from  closing  the trunk,
exhaust  can enter  the passenger
area. To avoid the possibility of ,
f ollow the instructions on page .
The air intake for the IMA battery
and electronics is located on top of
the rear shelf . Do not block this air
intake; it may cause the IMA battery
and the power control unit to
overheat, causing the IMA system to
shut down. It will start working again
af ter it cools.
Be sure items placed on the f loor
behind the f ront seats cannot roll
under the seats and interf ere with
the pedals or seat operation.
Keep the glove box closed while
driving. If it is open, a passenger
could injure their knees during a
crash or sudden stop. 52Air Intake

Apply the parking  brake.
In  cold  weather,  turn off all
electrical  accessories  to reduce
the  drain  on the  battery.
If the  engine  does not start  within
15  seconds,  or starts  but stalls
right  away,  repeat  step 4 with  the
accelerator  pedal pressed  halfway
down.  If the  engine  starts, release
pressure  on the  accelerator  pedal
so  the  engine  does not race.
If  the  engine  fails to start,  press
the  accelerator  pedal all the  way
down,  and hold  it there  while
starting  to clear  flooding.  If the
engine  still does  not start,  return
to  step  5. In 
cold  weather,  conventional  starter
is  used  instead  of the  IMA  system
starter.  This is normal.
Make  sure the shift  lever  is in
Park.  Press  on the  brake  pedal.
Without  touching  the accelerator
pedal,  turn the ignition  key to the
START  (III) position.  Do not  hold
the  key  in the  START  (III)
position  for more  than 15 seconds
at  a time.  If the  engine  does not
start  right  away,  pause  for at least
10  seconds  before trying again.

The  engine  is harder  to start  in cold
weather.  Also, the thinner  air found  at
altitudes  above 8,000 feet (2,400

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. You are pressing on the brake
pedal.
Fan speed lower f an speeds, in
either AUTO or manual modes. The f ront window def roster is of f .
Outside temperature is between
10 100 degrees F. The Auto Idle Stop f unction activates
if you speed up to over 8 mph
(12 km/h) and brake to a stop. And
it can activate twice even if you
speedupto8mph(12km/h)or
below and brake to a stop.
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 press the accelerator pedal.
You are on an incline, and the
vehicle begins rolling. The Auto Idle Stop f unction may
activate when you slow down.

To eliminate potential hazards, read
the instructions bef ore you begin,
and make sure you have the tools
and skills required.To clean parts, use a commercially
available degreaser or parts
cleaner, not gasoline.
To reduce the possibility of f ire or
explosion, keep cigarettes, sparks,
and flames away from the battery
and all f uel-related parts. Make sure your vehicle is parked
on level ground, the parking brake
is set, and the engine is of f . Some of the most important saf ety
precautions are given here. However,
we cannot warn you of every
conceivable hazard that can arise in
perf orming maintenance. Only you
can decide whether or not you
should perf orm a given task.Do
not run the engine unless
instructed to do so. Let the
engine and exhaust system cool
down bef ore touching any parts.
Wear eye protection and
protective clothing when working
with the battery or compressed air.
All service items not detailed in this
section should be perf ormed by a
certif ied technician or qualif ied
mechanic.
Be sure there is
adequate ventilation whenever you
operate the engine.

Check the condition of the 12 volt
battery monthly by looking at the
test indicator window. The label on
the battery explains the test
indicator’s colors.
If your vehicle’s 12 volt battery is
disconnected or goes dead, the IMA
battery level gauge reading will not
be correct the next time you turn the
ignition switch to the ON (II)
position. It will show less than the
actual level temporarily. It will show
the correct level af ter you drive f or
at least 30 minutes.
Check the terminals f or corrosion (a
white or yellowish powder). To
remove it, cover the terminals with a
solution of baking soda and water. It
will bubble up and turn brown. When
this stops, wash it of f with plain
water. Dry off the battery with a
cloth or paper towel. Coat the
terminals with grease to help prevent
f urther corrosion.
If additional battery maintenance is
needed, see your dealer or a
qualif ied technician.
Battery posts,
terminals, and related accessories
contain lead and lead compounds.
If you need to connect the battery to
a charger, disconnect both cables to
prevent damaging your vehicle’s
electrical system. Always disconnect
the negative ( ) cable first, and
reconnect it last.

WARNING:
Wash your hands af ter handling.

TEST INDICATOR WINDOW
The battery gives off explosive
hydrogen gas during normal
operation.
A spark or flame can cause the
battery to explode with enough
force to kill or seriously hurt you.
Wear protective clothing and a
face shield, or have a skilled
technician do the battery
maintenance.

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.
