Auto Idle Stop
To maximize fuel economy, your
Civic Hybrid has an Auto Idle Stop
function. Under certain conditions,
the engine will shut off 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 ECON mode is selected, and
the outside temperature is above
41°F (5°C), or the fan speed
control dial is off (see page
There is adequate vacuum reserve
for the power brakes.
When these conditions are met, the
engine will shut off as you come to a
stop. It will start again automatically
when you depress the clutch pedal
and move the shift lever to first 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 foot from the clutch pedal while
you are stopped. Sitting with the
clutch pedal depressed and the shift
lever in gear will cause the engine to
continue running, defeating the fuel
economy benefits of the Auto Idle
Stop function.
5-speed Manual Transmission
111 ). 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 shift lever is in Neutral, the
engine will restart so it can recharge
the IMA battery or replenish the
vacuum supply.
The Auto Idle Stop function may not
activate when starting the engine or
if the IMA battery temperature is too
hot or too cold.
