Turn Off the Start-Stop System

Last updated: June 7, 2026

Your Jaguar XE (2015–present) switches the engine off at a standstill to save fuel, then restarts it as you pull away. If you’d rather keep it running — in traffic or by preference — you can switch the system off in one press. Here’s how, and why it resets each drive.

Turning the System Off

1. With the engine running, press the stop/start (ECO) button on the centre console (an “A” inside a circular arrow).
2. An indicator confirms the system is off; the engine now stays running at a standstill.

The system defaults back to on each time you start the car, so disabling it is a per-drive choice — press the button again to re-enable it.

When the XE Disables Stop/Start Itself

Even with the system on, the XE won’t stop the engine when it isn’t appropriate, so continued idling isn’t necessarily a fault. It keeps the engine running when, for example, the cabin is still reaching temperature, the engine is cold, or the 12 V battery charge is low.

If Stop/Start Stops Working

• Check the battery. The system relies on a healthy, charged 12 V battery and a settled BMS; an ageing battery (or a recent disconnection) is the usual reason it stops cutting out.
• Seat belt fastened, doors and bonnet closed — open ones inhibit it.
• Fault light? A charging or sensor issue stores a code — decode it on autodtcs.com.

Frequently Asked Questions

How do I turn off stop/start on a Jaguar XE?

Press the ECO (“A”) button on the console; an indicator confirms it’s off until the next restart.

Does it stay off?

No — it resets to on every start, so press the button each drive if you want it off.

Why has my XE stopped switching the engine off?

Usually a low or ageing 12 V battery, a recent battery disconnection the BMS is still learning, or the engine/cabin not yet at temperature.

Is leaving it on harmful?

No — the system and starter are designed for it; switching off is purely preference.
