Applies to vehicles: with selective catalytic reduction

Fig. 193 Right rear vehicle side: removing the AdBlue cap

The AdBlue tank opening is located near the diesel tank opening Add at least 1 gallon (3.8 liters) of AdBlue. This is the minimum amount required to ensure the system detects the refilling and to start the engine. You can fill a maximum of 6 gallons (23 liters).

Requirement: The request to add AdBlue must appear in the instrument cluster display.

• Switch the ignition off.
• Open the tank door.
• Turn the tank cap counterclockwise with the lug wrench from the vehicle tool kit to remove it > fig. 193.
• Fill the AdBlue with the bottle or the canister.

WARNING

AdBlue can irritate the skin, eyes and respiratory system. If there is contact with the fluid, flush immediately with plenty of water. Consult a physician if necessary.

Note

• Only use AdBlue that conforms to the standard ISO 22241-1. Do not mix any additives with the AdBlue and do not dilute it with water.
• Do not add AdBlue to the diesel tank or add diesel fuel to the AdBlue tank. Mixing can lead to damage to the engine and the AdBlue tank system.
• AdBlue attacks surfaces such as painted vehicle components, plastic and carpet. Remove the fluid as quickly as possible with a damp cloth and plenty of cold water. If the AdBlue has already crystallized, use warm water and a sponge. AdBlue residue that is not removed will crystallize and can damage the affected surface.
• Do not store refill bottles or canisters permanently in the vehicle. If the container leaks, the escaping AdBlue could damage the vehicle interior.
• Do not allow AdBlue to come into contact with clothing. If there is contact with the fluid, flush immediately with plenty of water.

Tips

Follow the AdBlue manufacturer's instructions for use and storage.
