Air conditioning also removes mois-
ture from the air as it operates. You
can use it to def og the windows
quickly in cool or damp weather.
Used in combination with the heater,
it also makes the interior warm and
dry.
Air conditioning places an extra load
on the engine. Watch the engine
coolant temperature gauge (see page) when using the A/C in heavy
traf f ic or driving up long hills. If the
reading reaches near the red mark,
turn of f the air conditioning until the
gauge reads normally. 71

During this period:Avoid full-throttle starts and rapid
acceleration.
Avoidhardbraking.Newbrakes
need to be broken-in by moderate
use f or the f irst 200 miles (300
km). 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
a persistent, heavy metallic rapping
noise in the engine that can lead to
mechanical damage.
We recommend gasolines containing
detergent additives that help prevent
f uel system and engine deposits.
In Canada, some gasolines contain
an octane-enhancing additive called
MMT. If you use such gasolines,
your emission control system
perf ormance may deteriorate and
the Malf unction Indicator Lamp on
your instrument panel may turn on.
If this happens, contact your
authorized Honda dealer f or service.
Help assure your car’s f uture
reliability and perf ormance by paying
extra attention to how you drive
during the f irst 600 miles (1,000 km).
Using gasoline containing lead will
damage your car’s emissions
controls. This contributes to air
pollution.
Youshouldfollowthesesamere-
commendations with an overhauled
or exchanged engine, or when the
brakes are relined. Do not change the oil until the
recommended time or mileage
intervalshowninthemaintenance

Because the f uel f ill cap is on the
driver’s side of the car, park with
that side closest to the service
station pumps.
Open the f uel f ill door by pushing

driver’s seat.Remove the f uel f ill cap slowly.
You may hear a hissing sound as
pressure inside the tank escapes.
Place the cap in the holder on the
fuel fill door.
Stop f illing the tank af ter the f uel
nozzle automatically clicks of f . Do
not try to ‘‘top of f ’’ the tank, leave
some room f or the f uel to expand
with temperature changes.
Your car has an on-board ref ueling
vapor recovery system to help
keep f uel vapors f rom going into
the atmosphere. If the fuel nozzle
keeps clicking of f even though the
tank is not f ull, there may be a
problem with this system. Consult
your dealer.

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.
