AUTO IDLE STOP INDICATOR
This indicator comes on as a
reminder that the engine has
stopped because of the Auto Idle
Stop function. When the indicator is
off, 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. You cannot restart the
164
Driving
engine with the ignition switch when
this light is blinking.
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.
