2003 HONDA CIVIC HYBRID heating

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

This button controls the source of
the air going into the system. When
the indicator in this button is lit, air
from the car’s interior is sent
through the system again (Recircula-
tion mode). When the indicator is off,
air is brought in f rom outside the car
(Fresh Air mode).
Use Recirculation mode to heat or
cool the interior more quickly, or to
keep out smoke and dust. Leaving
the system in the Recirculation mode
with the A/C off can cause the

Air mode as soon as the interior
reaches a comf ortable temperature
or the outside smoky, dusty con-
dition clears.You can manually select the f an
speed by turning the f an speed
control dial. Turning this dial
clockwise increases the f an speed,
which increases air flow.
When the dial is set to AUTO, the
system controls the f an speed
automatically.
When the f an speed control dial is
of f , the Auto Idle Stop works under

Come to a full stop before you shift
into Reverse. You can damage the
transmission by trying to shif t into
Reverse with the car moving. Push
down the clutch pedal, and pause f or
a f ew seconds bef ore shif ting into
Reverse, or shif t into one of the
f orward gears f or a moment. This
stops the gears so they won’t ‘‘grind.’’
The manual transmission is syn-
chronizedinallforwardgearsfor
smooth operation. It has a detent so
you cannot shift directly from Fifth
to Reverse. When shif ting up or
down,makesureyoupushtheclutch
pedal down all the way, shift to the
next gear, and let the pedal up
gradually. When you are not shif ting,
do not rest your f oot on the clutch
pedal. This can cause your clutch to
wear out faster. When slowing down, you can get
extra braking f rom the engine by
shifting to a lower gear. This extra
braking can help you maintain a safe
speed and prevent your brakes f rom
overheating while going down a
steep hill. Bef ore downshif ting,
make sure the vehicle speed is low
enough that you will not activate the
engine speed limiter in the lower
gear. Make sure the engine speed
will not go into the tachometer’s red
zone in the lower gear bef ore
downshif ting.

This f ilter should be replaced every
30,000 miles (48,000 km) under
normal conditions. It should be
replaced every 15,000 miles (24,000
km) if you drive primarily in urban
areas that have high concentrations
of soot in the air f rom industry and
diesel-powered vehicles. Replace it
more of ten if air f low f rom the
