This message will display if the AdBlue® (UREA) system issue detected is not serviced during the allowed
period. Your engine will not restart unless your vehicle is serviced by an authorized dealer. If the level is not
resolved, an additional warning appears whenever a certain threshold is reached until it will no longer be
possible to start the engine. When 125 miles (200 km) are remaining before the AdBlue® tank is empty, a
message will appear on the instrument panel, accompanied by a buzzer sound.

NOTE:
The display may take up to five seconds to update after adding 2 gallons (7.5 Liters) or more of AdBlue®
(UREA) to the AdBlue® (UREA) tank. If you have a fault related to the AdBlue® (UREA) system, the display
may not update to the new level. See an authorized dealer for service.
AdBlue® freezes at temperatures lower than 51.8°F (11°C). If the car stands for a long time at this
temperature, refilling could be difficult. For this reason, it is advised to park the vehicle in a garage and/
or heated environment, and wait for the AdBlue® (UREA) to return to liquid state before topping up.
