Last updated:
The Stop & Start system on your Renault Kadjar (XFE, 2015–2022) cuts the engine at a standstill to save fuel. When you’d rather keep it running — stop-go traffic, a hot day, or before any under-bonnet work — one button turns it off.
Switching It Off
- Find the Stop & Start button — marked with an A inside a circular arrow (often shown as ‘AⓇ’) on the dash or centre console.
- Press it once; the indicator confirms the system is off and the engine no longer cuts at stops.
Why It Comes Back On
The Kadjar re-enables Stop & Start every time you restart the car — there’s no permanent off. Press the button at the start of each drive if you want it disabled.
When It Won’t Stop the Engine Anyway
Even with the system on, the Kadjar keeps running if the battery charge is low, the cabin still needs heating or cooling, or you’re on a slope — all normal protective behaviour, often tied to 12 V battery condition.
Frequently Asked Questions
How do I turn off auto stop/start on a Renault Kadjar?
Press the ‘AⓇ’ Stop & Start button; the indicator shows it’s disabled for this drive.
Can I disable it permanently?
No — it re-arms each time you start the car, so press the button each drive.
Why didn’t the engine stop today?
Low battery charge, climate demand or a gradient will keep it running by design.
Is it bad to leave it on?
No — it’s designed for constant use, but a tired 12 V battery can make it behave erratically.
If a Stop & Start fault symbol shows, it often points to the 12 V battery — see our Kadjar battery guide, or look the code up on autodtcs.com.
