2021 SUBARU LEGACY engine

If the engine is temporarily stopped by the system, the Auto Start-Stop indicator light on
the combination meter will illuminate in green. This indicator light will turn off when the
system restarts the engine.
There are several operating conditions for this system to operate as intended. Please refer
to the Owner’s Manual for further information.
Fuel Saving Display
Once the Auto Start-Stop System has stopped
the engine, the Fuel Saving Display will appear
in the Combination Meter Display (CMD),
showing how much time the engine was off in
the top line and the amount of fuel saved in
the bottom line. These are the total stop time
and fuel saved since the trip meter was reset.
No Activity Detected Indicator Light
If the operational conditions are not met when the vehicle is stopped, the
engine will not stop and the Auto Start-Stop No Activity Detected indicator
light will illuminate. This indicator is solid white when illuminated. It will turn off
when the vehicle begins to drive.
Auto Start-Stop Warning Light
The Auto Start-Stop warning light will illuminate in yellow when initially turning
the ignition switch to the “ON” position. The light will turn off after the engine
has started.
NOTE: If the Auto Start-Stop warning light does not turn off or is flashing
yellow after the engine has started, the Auto Start-Stop system may be malfunctioning. We
recommend that you contact your authorized SUBARU Retailer for an inspection.
