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.
Temperature Gauge
This shows the temperature of the
engine's coolant. During normal
operation, the reading should be in
the middle of the gauge. In severe
driving conditions, the reading may
reach near the red mark. If it
reaches the red (Hot) mark, pull
safely to the side of the road. Turn to
page 187 for instructions and
precautions on checking the engine's
cooling system.
