The engine stops automatically only if all of these are met
- Bonnet, driver's door closed; driver's seat belt fastened.
- Car fully stopped with the brake pressed and the accelerator fully released; you didn't stop with an emergency stop.
- Gear selector in D or M.
- Stop-start switched on, with no system fault.
- ACC not switched on and AEB not active.
- Battery charge at least 70%; brake vacuum sufficient; drivetrain allows it.
- Engine coolant above 48°C; outside temperature 3°C or more.
- Not at high altitude (below 2,800 m) and not on a steep slope (less than 10% up or down).
- Steering wheel turned less than 270°.
- Since starting off (or since a large steering turn), you've reached at least 4 mph (8 km/h).
- If the battery negative cable has been disconnected, at least 4 hours have passed since reconnection.
- The air conditioning's demands (demisting, cooling, heating) are satisfied.
The engine restarts when you…
Provided the driver's door and bonnet are closed, the driver's belt is fastened, stop-start is on and there's no fault, the engine restarts if:
- You press the accelerator in D, M or R, or select R.
- You turn the steering wheel more than 30°.
- The air conditioning needs it.
- You switch stop-start off.
- In N or P with your foot off the brake, you press the brake.
- In N with your foot off the brake, you select D or M.
- You shift from P or N to D or M without fully releasing the brake.
- In D or M with your foot on the brake, you release the brake. (If AUTO HOLD is holding the car, the engine restarts when you press the accelerator instead.)
Automatic safety restarts
The engine also restarts by itself, without you doing anything, if:
- The car starts rolling (above 1 mph / 2 km/h).
- The battery charge or brake vacuum gets too low.
- The engine has been stopped for more than 3 minutes.
- Engine coolant temperature goes beyond its limit.
