Engine All (4xWD, CAR, Heavy transporter, Light transporter)

Pour AdBlue® only into suitable containers. Wait until the pressure is released before starting any work on the exhaust aftertreatment system.

Potential risks

Risk of burn injuries and scalding

The AdBlue® lines and all components attached to them are under pressure during operation and remain so after the engine is switched off; they may be hot. There is a risk of burn injuries. There is a risk of scalding caused by escaping hot AdBlue® when the line system is opened.

Risk of injury

There is a risk of skin irritation and eye damage on contact with AdBlue®.

Risk of poisoning

There is a risk of poisoning if AdBlue® is swallowed.

Rules of conduct

In vehicles with an electric delivery pump, the AdBlue® is pumped back from the line into the AdBlue® tank after the engine is switched off.

On vehicles with a compressed air system, individual lines are flushed with compressed air after the engine is switched off. For this reason, work on the exhaust gas aftertreatment system may not be started until at least 5 minutes have elapsed after the engine is switched off.

Open connections and plugs on the system components slowly. Cover the connecting point with rags when opening.
Pour AdBlue® only into marked containers specially intended for the purpose. Do not pour AdBlue® into drinking containers.
Wipe up any AdBlue® spills immediately because there is a high risk of someone slipping.

Safety precautions for handling removed parts and working under the vehicle

Wear suitable protective gloves.
Wear protective clothing.
Wear safety glasses.

First aid measures

Contact with skin: Wash the affected skin areas with plenty of clean water. Change moistened clothing as quickly as possible.

Contact with eyes: In the event of contact with eyes, immediately rinse eyes thoroughly with plenty of clear water; contact an eye doctor if necessary.

Ingestion: Rinse mouth with clean water and drink large quantities of water. Seek medical assistance immediately.

Fire-fighting measures

AdBlue® is not combustible. NH3 (ammonia) can be released in the event of fire, causing a risk of poisoning. Firefighting measures must therefore be suited to the surroundings.
