Your Suzuki SX4 S-Cross Mk1 (JY, 2013–2021) — on versions fitted with it — has an engine start/stop (ENG A-STOP) system that switches the engine off when you come to a halt and restarts it as you pull away. It saves fuel, but some drivers prefer to switch it off in stop-go traffic or when manoeuvring. This guide shows how to deactivate it, including the seatbelt trick, and why it sometimes won’t engage.
How Start/Stop Works on the S-Cross
When you brake to a stop (and conditions allow), the system shuts the engine down to save fuel. Lifting the brake or pressing the clutch restarts it automatically. On Smart Hybrid (SHVS) versions a small integrated starter-generator makes the restart especially smooth.
Method 1 — The Dashboard Button
- With the engine running, find the ENG A-STOP OFF button on the dashboard (marked with an “A” inside a circular arrow).
- Press it once. The warning light illuminates to confirm the system is switched off.
- The engine will now idle normally at a stop.
Method 2 — Undo the Driver’s Seatbelt
The S-Cross also suppresses auto-stop when the driver isn’t belted in or the door is open:
- Disconnect the driver’s seat belt from the buckle, or
- Open the driver’s door.
- With either condition present, the system will not stop the engine.
The button (Method 1) is the proper way to disable it for a drive.
How to Switch It Back On
Press the ENG A-STOP OFF button again so the warning light goes out, or simply restart the car — the system defaults back to ON every time you switch the ignition off and on.
Why It Sometimes Won’t Activate
Even with the system enabled, the S-Cross skips auto-stop to protect comfort and components when:
- The engine is not yet up to temperature.
- The battery charge is low — common after a battery change or lots of short trips.
- Cabin heating or demisting needs the engine running.
- The steering is turned, or the car is on a steep slope.
If it stopped working entirely after a battery disconnection, the battery needs to recharge — see our S-Cross battery guide.
Frequently Asked Questions
Does the S-Cross remember my start/stop setting?
No — it resets to ON every time you restart the car. Press the OFF button each drive if you prefer it disabled.
Is it bad to keep using start/stop?
No. The S-Cross’s starter and battery are built for it, and the system skips stops when the battery is low to protect itself.
Why did it stop working after a flat battery?
It only runs when the battery is well charged. After a jump-start or battery change it stays dormant until charge recovers; a few longer drives usually restore it.
Can I turn it off permanently?
Not from the dashboard — the button is per-drive only. A permanent change would need dealer-level configuration, which most owners skip given the simple button.
