2004 HONDA CIVIC HYBRID engine

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 vehicle’s speed is below 19
mph (30 km/h) and you are
pressing on the brake pedal to
come to a stop.
You depress the clutch pedal.
You are not pressing on the
accelerator pedal.
The IMA battery is charged
enough to operate the system. The Auto Idle Stop f unction may not
activate if the IMA battery
temperature is too hot or too cold. During Auto Idle Stop, the IMA
charge and power brake vacuum
reserve is monitored by the system.
If either drops below a desired level,
and the shif t lever is in Neutral, the
engine will restart so it can recharge
the IMA battery or replenish the
vacuum supply.
The ECON mode is selected, and
the outside temperature is above
f reezing, or the f an speed control
dial is off (see page ).
There is adequate vacuum reserve
f or the power brakes.
When these conditions are met, the
engine will shut of f as you come to a
stop. It will start again automatically
when you depress the clutch pedal
f ully and move the shif t lever to f irst
gear. There is no need to start the
engine with the ignition switch.
It is recommended that you move
the shift lever to Neutral and remove
your f oot f rom the clutch pedal while
you are stopped. Sitting with the
clutch pedal depressed and the shif t
lever in gear will cause the engine to
continue running, def eating the f uel
economy benef its of the Auto Idle
Stop f unction. 89

This indicator will blink, and you will
hear a continuous beep, if you open
the door when Auto Stop is active.
The beep will stop when you close
the door.
Always turn the ignition switch to
LOCK (0) and remove the key if you
are getting out of the vehicle.
This indicator comes on as a
reminder that the engine has
stopped because of the Auto Idle
Stop f unction. When the indicator is
of f , it means that Auto Idle Stop is
not active. When the indicator is on,
but the engine is not running, it
means the clutch pedal is depressed,
but the transmission is not in gear.
When the indicator is blinking, it
means the clutch pedal is not
depressed completely. You cannot restart the engine with the ignition
switch when this light is blinking.
Either the Shift Up or Shift Down
indicator will light to show the best
time to shift to a higher or lower
gear. You can achieve the best f uel
economy by accelerating and
decelerating slowly, and shif ting
when prompted by the Shif t Up
indicator.
Road and traffic conditions may
require you to shif t at times other
than those indicated.

This position mechani-

Press the brake

Reverse to Neutral, come to a

Use Neutral if you
need to restart a stalled engine, or if
it is necessary to stop brief ly with
the engine idling. Shif t to the Park
position if you need to leave your
vehicle for any reason. Press on the
brake pedal when you are moving
the shift lever from Neutral to
another gear.
Use this position f or
your normal driving. The transmis-
sion automatically selects a suitable
gear f or your speed and acceleration.
You may notice the transmission
shif ting up at higher speeds when
the engine is cold. This helps the
engine warm up f aster. Selecting Second
shifts the transmission into a lower
range of ratios for better
acceleration and increased engine
braking. Use Second when you are
going down a steep hill, or in stop-
and-go driving.
To shif t to Low, press
the release button on the front of the
shif t lever. Use Low to get more
power when climbing, and f or
maximum engine braking when
going down steep hills.
ForfasteraccelerationwheninD,S
or L, the transmission will
automatically ‘‘kick down’’ to a lower
range of ratios by pushing the
accelerator pedal to the floor. When the vehicle reaches the
maximum speed in any shif t position,
you may f eel the engine cut in and
out. This is caused by a limiter (112
mph, 180 km/h) in the engine’s
computer controls. The engine will
run normally when you reduce the
speed to below the maximum.

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.
The ECON mode is selected, and
the outside temperature is above
f reezing, or the f an speed control
dial is off (see page ). There is adequate vacuum reserve
f or the power brakes.
When these conditions are met af ter
the vehicle speed has exceeded 10
mph (16 km/h), the engine will shut
of f as you are braking to a stop and
the vehicle speed goes below 5 mph
(8 km/h).
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 are on an incline, and the
vehicle begins rolling. During Auto Idle Stop, the IMA
charge and power brake vacuum
reserve is monitored by the system.
If the vacuum reserve drops below
an optimal level, the engine will
restart to replenish the vacuum
supply. If the IMA charge drops
below an optimal level and the shif t
lever is in Neutral or Park (P), the
engine will restart to recharge the
IMA battery.
The Auto Idle Stop f unction may not
activate if the IMA battery
temperature is too hot or too cold.
You press the accelerator pedal.

close the door.
With the driver’s door open, you will
hear a continuous beep even if the
Auto Idle Stop f unction is
deactivated and the engine restarts.
Always turn the ignition switch to

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
