Charge/Assist Gauge
IMA CHARGE IMA ASSIST
GAUGE GAUGE
This gauge shows you the status of
the Integrated Motor Assist (IMA).
When the IMA battery is being
charged, the left side of the gauge
illuminates. When the IMA is
assisting the engine, the right side of
the gauge illuminates.
If the IMA battery is too hot or too
cold, the IMA system shuts down to
protect the battery. This disables the
IMA assist and Auto Idle Stop, even
though the Battery Level Gauge may
show that the battery is well-charged.
Therefore, those functions may not
operate when you first start driving
in very hot or cold weather.
The battery temperature will
normalize after a few minutes of
driving, and the IMA system will
work normally.
