Direct answer
On the covered Kohler standby generator, Not in Auto means warning. The generator set is not in AUTO (standby) mode, so remote start and stop commands from a transfer switch or remote switch are ignored. First, confirm nobody left the set in OFF or RUN after service.
Definition versus diagnosis
The display names a detected condition—not an automatically failed part.

Match every character and the exact product
ReversiblePhotograph the complete display and product label. This record covers Not in Auto on Kohler residential standby generator sets using the RDC2/DC2 controller; the displayed fault text, warning/shutdown behaviour and available customer checks vary by model and controller firmware. Confirm against the operation manual for the exact model.
Preserve the failure state
ReversibleConfirm nobody left the set in OFF or RUN after service. Record the operating stage, recent change and what still works before clearing the message.
Correct only the documented fault domain
ReversiblePress AUTO to place the generator set in automatic mode when appropriate. Do not borrow a reset or meaning from a similar code, product or model year.
Verify once, then respect the service boundary
ReversibleRepeat only the shortest safe action that reaches the original stage. If Not in Auto returns, stop repeated resets and use model-specific manufacturer support.

Common follow-ups
What does Not in Auto mean on a Kohler standby generator?+
Warning. The generator set is not in AUTO (standby) mode, so remote start and stop commands from a transfer switch or remote switch are ignored.

A reset may hide the display temporarily but does not correct the documented fault. Record the code and complete only the safe checks first.
Why is the complete model number required?+
Manufacturers reuse characters across platforms. The model number determines which official table, controls and service boundary apply.
When should I stop?+
Stop for smoke, arcing, burning odor, uncontrolled water, gas odor, battery swelling, extreme heat or any condition the manufacturer directs to professional service.
