2003 HONDA CIVIC HYBRID Owners Manual

The condition of your car and your
driving habits are the two most
important things that affect the fuel
mileage you get.
Always maintain your car according
to the maintenance schedule. This
will keep it in top operating condition.
An important part of that mainte-
nance is the(see page ). For
example, an underinf lated tire
causes more ‘‘rolling resistance,’’
which uses f uel. It also wears out
f aster, so check the tire pressure at
least monthly. You can improve f uel economy by
driving moderately. Rapid acceler-
ation, abrupt cornering, and hard
braking use more f uel.
To get the best f uel mileage, drive in
the highest gear that is practical for
the speed you are driving, and
always accelerate slowly.
Engine oil also af f ects f uel economy.
The f uel ef f icient, low-viscosity
0W-20 oil recommended f or your
Civic Hybrid is f ormulated to help
the engine use less f uel. This oil is
available at your Honda dealer.
In winter, the build-up of snow on
your car’s underside adds weight and
rolling resistance. Frequent cleaning
helps your f uel mileage and reduces
the chance of corrosion.
You may f ind that your Civic Hybrid’s
unique combination of an engine and
an electric motor has driving
characteristics that are somewhat
dif f erent f rom what you are used to.
Shif t Up and Shif t Down indicators
(5-speed manual transmission only)
on the instrument panel show when
to shif t to a higher or lower gear. By
shifting as soon as the indicator
comes on, you will keep the engine
operating in its most economical
range.

The air conditioning puts an extra
load on the engine which makes it
usemorefuel.Turnoff theA/Cto
cutdownonairconditioninguse.
Use the f low-through ventilation
when the outside air temperature is
moderate.
If air conditioning is needed, you can
save some f uel by using the A/C in
‘‘ECON’’ mode. When the outside
temperature is above 41°F (5°C),
this mode allows the Auto Idle Stop
f unction to shut of f the engine when
the vehicle is stopped, resulting in
fuel savings.
Depending on traf f ic conditions, try
to maintain a constant speed. Every
time you slow down and speed up,
your car uses extra f uel. Use the
cruise control, when appropriate, to
increase f uel economy.
Wind resistance causes vehicles to
usemorefuelathigherspeeds.
Driving at moderate speeds on the
highway reduces wind resistance
and conserves f uel.
A cold engine uses more f uel than a
warm engine. It is not necessary to
‘‘warm-up’’ a cold engine by letting it
idle f or a long time. You can drive
away in about a minute, no matter
how cold it is outside. The engine
will warm up f aster, and you get
better f uel economy. To cut down on
the number of ‘‘cold starts,’’ try to
combine several short trips into one. You may notice that using the A/C
causes a greater drop in f uel
economy than you are used to in
other vehicles. Although the amount
of extra f uel used by the A/C load on
the engine is no greater than other
vehicles, it is more noticeable
because of your Civic Hybrid’s
excellent f uel mileage. Using the
A/C in hot weather may result in
f uel economy that is lower than
expected.

Modif ying your car, or installing
some non-Honda accessories, can
make your car unsaf e. Bef ore you
make any modif ications or add any
accessories,besuretoreadthe
f ollowing inf ormation.When properly installed, cellular
phones, alarms, two-way radios, and
low-powered audio systems should
not interf ere with your car’s
computer-controlled systems, such
as the SRS and anti-lock brake
system.If possible, have your dealer inspect
the f inal installation.Have the installer contact your
Honda dealer f or assistance bef ore
installing any electronic accessory. Be sure electronic accessories do
not overload electrical circuits
(see page ). Make sure the accessory does not
obscure any lights, or interf ere
with proper car operation or
perf ormance.
Bef ore installing any accessory: However, if electronic accessories
are improperly installed, or exceed
your car’s electrical system capacity,
they can interfere with the operation
of your car, or even cause the
airbags to deploy.
Your dealer has Honda accessories
that allow you to personalize your car.
These accessories have been
designed and approved f or your car,
and are covered by warranty.
Non-Honda accessories are usually
designed f or universal applications.
Although aftermarket accessories
may f it on your car, they may not
meet f actory specif ications, and
could adversely af f ect your car’s
handling and stability. (See

Improper accessories or
modifications can affect your
car’s handling, stability and
performance, and cause a
crash in which you can be hurt
or killed.
Follow all instructions in this
owner’s manual regarding
accessories and modifications.

If a side airbag
inflates,acupholderorotherhard
object attached on or near the
door could be propelled inside the
car and hurt someone.
Covering the outside edge of a
f ront seat-back, with a non-Honda
seat cover for example, could
prevent the airbag from inflating
properly.
Some examples are:
Lowering the vehicle with an
aftermarket suspension kit that
signif icantly reduces ground
clearance can allow the
undercarriage to impact speed
bumps or other raised objects,
which could cause the airbags to
deploy.
Raising the vehicle with an
af termarket suspension kit can
af f ect the handling and stability.
Af termarket wheels, because they
are a universal design, can cause
excessive stress on suspension
components. Larger or smaller wheels and tires
can interf ere with the operation of
your vehicle’s anti-lock brakes and
other systems.
Do not modif y your steering wheel
or any other part of your
Supplemental Restraint System.
Modif ications could make the
system inef f ective.
Any object
attached to or placed on the covers
marked ‘‘SRS AIRBAG,’’ in the
center of the steering wheel and
on top of the dashboard, could
interf ere with the proper operation
of the airbags. Or, if the airbags
inf late, the objects could be
propelled inside the car and hurt
someone.
If you plan to modif y your vehicle,
consult with your Honda dealer.
Removing parts f rom your vehicle,
or replacing components with non-
Honda (af termarket) components
could seriously af f ect your vehicle’s
handling, stability, and reliability.

Your car has several convenient
storage areas so you can stow cargo
saf ely.
The glove box, and the pockets in
the front doors and seat-back, are
designed f or small, lightweight items.
The trunk is intended f or larger,
heavier items.
However, carrying too much cargo,
or improperly storing it, can af f ect
your car’s handling, stability, and
operation and make it unsafe. Before
carrying any type of cargo, be sure to
read the f ollowing pages.

Store or secure all items that could
be thrown around and hurt
someone during a crash.
Be sure items placed on the f loor
behind the f ront seats cannot roll
under the seats and interf ere with
the driver’s ability to operate the
pedals, or with the proper
operation of the seats.
Keep the glove box closed while
driving. If the lid is open, a
passenger could injure their knees
during a crash or sudden stop. Do not put any items on top of the
trunk panel. They can block your
view and be thrown around the car
during a crash.
The maximum load for your car is
850 lbs in U. S. models and 395 kg in
Canadian models.
This f igure includes the total weight
of all occupants, cargo, and
accessories.
To f igure out how much cargo you
can carry:
Add up the weight of all occupants.
Subtract the total f rom 850 lbs in

Follow all load limits and other
loading guidelines in this
manual.

Distribute cargo evenly on the
f loor of the trunk, placing the
heaviest items on the bottom and
as far forward as possible.If you can carry any items on a
roof rack,besurethetotalweight

The air intake f or the IMA battery is
located on top of the trunk panel. Do
not block this air intake, it may cause
the IMA battery and the power
control unit to overheat, causing the
IMA to shut down. It will start
working again af ter it cools.Do not spill any liquids over the air
intake and also do not put any small
f oreign objects in it. This may
damage the IMA battery and the
power control unit.
