The volume of the tank on your C Elysée is 17L.
When the remaining driving range is between 375 and 1500 miles, a UREA warning illuminates and a signal lights up every 200 miles. This signal appears until your autonomy reaches 375 miles and you fill up. Between 0 and 375 miles, the warning light SERVICE illuminates and the indicator UREA flashes, along with an audible signal and the display of a message indicating the remaining mileage. The message is shown every 30 seconds if the level has not been adjusted. When the tank is empty, put a minimum of 3,8L in the tank to turn off the warning light. The use of a 5L can is recommended.
Once your tank is empty, you will not be able to restart the engine after it has stopped. If your engine is still running, you can drive to a gas station as long as you do not cut the engine. In case of a breakdown, wait for 5 minutes after adding AdBlue® to turn on the ignition, without opening the drivers' door, unlocking the vehicle or putting the key in the ignition. Switch on the ignition and, 10 seconds later, turn on the engine.
