DS 3: Indicators / AdBlue® range indicators (BlueHDi)

The Diesel BlueHDi engines are equipped with a system that associates the SCR (Selective Catalytic Reduction) emissions control system and the Diesel particle filter (DPF) for the treatment of exhaust gases. They cannot function without AdBlue® fluid.

When the level of AdBlue® falls below the reserve level (between 1,500 and 0 miles (2,400 and 0 km)), a warning lamp lights up when the ignition is switched on and an estimate of the distance that can be travelled before engine starting is prevented is displayed in the instrument panel.

The engine starting prevention system required by regulations is activated automatically once the AdBlue® tank is empty. It is then no longer possible to start the engine until the minimum level of AdBlue® has been topped up.

Manual display of driving range

While the driving range is greater than 1,500 miles (2,400 km), it is not displayed automatically.

You can view the range information by pressing the "Check" button in the Driving/ Vehicle touch screen menu.

Actions required related to a lack of AdBlue®

The following warning lamps light up when the quantity of AdBlue® is below the reserve level: driving range of 1,500 miles (2,400 km).

Together with the warning lamps, messages regularly remind you of the need to top up to avoid engine starting being prevented. Refer to the Warning and indicator lamps section for details of the messages displayed.

For more information on AdBlue® (BlueHDi) and in particular on topping up, refer to the corresponding section.

Malfunction of the SCR emissions control system

Malfunction detection

The alert is triggered while driving when the fault is detected for the first time, and thereafter when switching on the ignition for subsequent journeys, for as long as the cause of the fault persists.

If the fault is temporary, the alert disappears during the next journey, after self-diagnostic checks of the SCR emissions control system.

Malfunction confirmed during the permitted driving phase (between 685 miles and 0 miles (1,100 km and 0 km))

If the fault indication is still displayed permanently after 31 miles (50 km) of driving, the fault in the SCR system is confirmed.

The AdBlue warning lamp flashes and a message is displayed ("Emissions control fault: starting prevented in X miles (kms)"), indicating the driving range in miles or kilometres.

While driving, the message is displayed every 30 seconds. The alert is repeated when switching on the ignition.

You can continue driving for up to 685 miles (1,100 km) before the engine starting prevention system is triggered.

Have the system checked by a dealer or a qualified workshop as soon as possible.

Starting prevented

Every time the ignition is switched on, the message "Emissions control fault: Starting prevented" is displayed.

To restart the engine

Contact a dealer or a qualified workshop.
