These instructions apply to the Nissan X-Trail Mk4 (T33) 2022-Present.

The mild-hybrid Nissan X-Trail Mk4 (T33, 2022–present) has a Stop/Start system that switches the engine off at a standstill to save fuel. If you’d rather keep it running, it’s one button to turn off. (On the e-Power X-Trail the petrol engine is a generator that the car starts and stops on its own — there’s no conventional Stop/Start button to press.)
How It Works on the mHEV X-Trail
Brake to a halt and the engine shuts off; lift the brake and it restarts smoothly via the mild-hybrid starter-generator. It only operates once the engine is warm and the 12 V battery is healthy.
How to Switch It Off
- With the engine running, press the Stop/Start OFF button — the “A” inside a circular arrow, on the dash or centre console.
- A dash light confirms the system is off, and the engine idles normally at a stop.
How to Switch It Back On
Press the button again, or simply restart the car — Stop/Start defaults back on every time you switch off and restart.
Why It Sometimes Won’t Stop the Engine
- The engine isn’t warm yet, or the climate system is demanding heating/cooling/demist.
- The 12 V battery charge is low — common after short trips or a battery change.
- You’re on a slope, the steering is turned, or you haven’t fully stopped.
If it stopped working after a battery change, let the battery fully charge — see our X-Trail Mk4 battery guide.
Frequently Asked Questions
Does the X-Trail remember my Stop/Start setting?
No — on the mild-hybrid it returns to on at every start.
My X-Trail is the e-Power — where’s the button?
e-Power runs the wheels on electric motors and uses the petrol engine as a generator, starting and stopping it automatically — so there’s no Stop/Start button to switch off.
Why won’t the engine auto-stop (mHEV)?
Usually a cold engine, a low 12 V battery, or the climate system needing the engine.
Is the stopping and starting bad for the engine?
No — the mild-hybrid hardware and battery are designed for it.
