Press the 'AS&G OFF' button on the dashboard of the 2012–2020 Mitsubishi Outlander to switch the automatic engine stop/start off; an indicator light confirms it is disabled. The setting only lasts for the current drive — AS&G turns itself back on every time you restart the engine, and there is no factory way to keep it off permanently.
Overview
Auto Stop & Go (AS&G) is Mitsubishi's fuel-saving system that shuts the engine off when the car is stationary and restarts it as you pull away. On the third-generation Outlander it is armed automatically at every start and shown by an 'A' inside a circular arrow in the instrument cluster. Mitsubishi provides only a temporary off switch, because the system is intended to be left running.
Applies to
2012–2020 Mitsubishi Outlander (third generation, GF/GG) with the AS&G idle stop/start system. Petrol models; the PHEV uses a different hybrid strategy. Button placement can vary by trim and market.
What you’ll need
- No tools required — this is a dashboard button
Step-by-step
- Find the AS&G OFF button — It is labelled 'AS&G OFF' with an 'A'-in-a-circular-arrow symbol, on the driver-side dashboard switch panel near the steering column.
- Press AS&G OFF with the engine running — A single press disables the system; an indicator light comes on to confirm AS&G is off.
- Confirm it is off — The engine will no longer shut down when you stop; the auto-stop symbol is no longer active.
- Re-enable when you want it back — Press AS&G OFF again, or restart the car — the system re-arms on the next engine start.
Important
- The off state does not stick — AS&G re-arms every time you start the engine, so you must press AS&G OFF again each drive if you want it off.
- There is no factory menu or coding option to disable AS&G permanently; only dealer-level configuration or aftermarket hardware could, with a warranty risk.
- AS&G will not stop the engine when the battery charge is low, the cabin is still heating or cooling, or the engine is cold — that is normal, not a fault.
FAQ
Can I turn Outlander AS&G off permanently?
Not with a factory setting. The Outlander re-arms AS&G at every start and offers no persistent menu option. Lasting solutions are aftermarket modules that carry a warranty risk.
Why does the engine keep switching itself off at junctions?
That is AS&G working normally — it stops the engine at a standstill to save fuel and restarts it when you move off. Press AS&G OFF to stop that behaviour for the drive.
Is frequent auto start/stop bad for the engine?
Cars fitted with AS&G use a heavier-duty starter and battery designed for repeated restarts, so ordinary use is not harmful. Just be aware the battery is a specific enhanced type at replacement time.
Why won't AS&G stop my engine in winter?
In cold weather, or when the heater is working hard, or when the battery is not fully charged, AS&G keeps the engine running to protect comfort and the battery. This is expected behaviour.
