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 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
freezing, or the fan speed control
dial is off (see page
87
There is adequate vacuum reserve
for the power brakes.
When these conditions are met after
the vehicle speed has exceeded 10
mph (16 km/h), the engine will shut
off 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 shift lever from D
or N to R or L.
You press the accelerator pedal.
).
You are on an incline, and the
vehicle begins rolling.
Automatic Transmission (CVT)
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 shift
lever is in Neutral or Park (P), the
engine will restart to recharge the
IMA battery.
The Auto Idle Stop function may not
activate if the IMA battery
temperature is too hot or too cold.
