Risk of injury!
At high outside temperatures, ammoniac fumes may escape when the fuel tank cap is opened.
Ammoniac fumes have a pungent odor and irritate the skin, mucous membranes, and eyes.
This can cause a burning sensation in the eyes, nose, and throat, as well as coughing and watery
eyes.
Do not inhale ammoniac fumes.
Only fill up the AdBlue/DEF tank in well-ventilated areas.
