SCR emissions control system



This alert uses the AdBlue®, Service and engine self-diagnosis lamps together, with a beep and a message. It means a fault has been detected with the SCR emissions control system, and how the lamps behave shows how serious it is.
What to do:
If all three lamps stay on when you switch on the ignition, with a message:
- A fault with the SCR system has been detected.
- The alert goes away once exhaust emissions are back to normal levels.
If the AdBlue® lamp flashes and the Service and engine self-diagnosis lamps stay on, with a message showing the remaining range:
- Depending on the message, you can drive for up to 685 miles (1,100 km) before the engine is prevented from starting.
- Contact a qualified professional as soon as possible to avoid this.
If the AdBlue® lamp flashes and the Service and engine self-diagnosis lamps stay on, with a message saying the engine cannot restart:
- The authorised driving limit has been passed after a confirmed emissions fault, so an immobiliser stops the engine from restarting.
- To start the engine, contact a qualified professional.
Rear foglamp

This is the rear foglamp indicator. When it stays on, your rear foglamp is on.
