2004 HONDA CIVIC HYBRID check engine

Always maintain your vehicle
according to the maintenance
schedule. See(see page
).
an underinf lated tire
causes more ‘‘rolling resistance,’’
which uses f uel. Try to maintain a constant speed.
Everytimeyouslowdownand
speed up, your vehicle uses extra
fuel.Usethecruisecontrolwhen
appropriate.
Combine several short trips into
one.
The air conditioning puts an extra
load on the engine which makes it
usemorefuel.Usethefresh-air
ventilation when possible.
Drive moderately. Rapid
acceleration, abrupt cornering and
hard braking use more f uel.
Always drive in the highest gear
possible.
You may find 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.
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.
The build-up of snow or mud on
your vehicle’s underside adds
weight and rolling resistance.
Frequent cleaning helps your f uel
mileage and reduces the chance of
corrosion. 146

Make sure all windows, mirrors,
and outside lights are clean and
unobstructed. Remove f rost, snow,
or ice.
Check that the hood and trunk are
f ully closed.
Visually check the tires. If a tire
looks low, use a gauge to check its
pressure.Check that any items you may be
carrying are stored properly or
f astened down securely.
Check the seat adjustment (see
page ).
Check the adjustment of the
inside and outside mirrors (see
page ).
Check the steering wheel
adjustment (see page ).
Make sure the doors are securely
closed and locked.Fasten your seat belt. Check that
your passengers have f astened
their seat belts (see page ).
When you start the engine, check
the gauges and indicator lights in
the instrument panel (see page
).

Check the brakes after driving
through deep water. Apply the
brakes moderately to see if they f eel
normal. If not, apply them gently and
f requently until they do. Be extra
cautious in your driving.
The hydraulic system that operates
the brakes has two separate circuits.
Each circuit works diagonally across
the vehicle (the lef t-f ront brake is
connected with the right-rear brake,etc.). If one circuit should develop a
problem, you will still have braking
at two wheels.
If the brake pads need replacing, you
will hear a distinctive, metallic
screeching sound when you apply
the brake pedal. If you do not have
the brake pads replaced, they will
screech all the time. It is normal f or
the brakes to occasionally squeal or
squeak when you apply them.
Your Honda is equipped with f ront
disc brakes. The brakes on the rear
wheels are drum. A power assist
helps reduce the ef f ort needed on
thebrakepedal.TheABS(onsome
models) helps you retain steering
control when braking very hard.
Resting your f oot on the pedal keeps
the brakes applied lightly, builds up
heat, and reduces their ef f ectiveness.
It also keeps your brake lights on all
the time, conf using drivers behind
you.
Constant application of the brakes
when going down a long hill builds
up heat and reduces their ef f ective-
ness. Use the engine to assist the
brakes by taking your f oot of f the
accelerator and downshif ting to a
lower gear. Braking System Design
