IMPORTANT

If the “DEF” tank cap is opened at high temperatures, ammonia vapours may escape. Ammonia vapours have a pungent odour and are particularly irritating to
- the skin
- the mucous membranes
- the eyes
The presence of such vapours can result in burning eyes, nose, and oral cavities, as well as coughing and tearing.
Avoid inhaling ammonia vapours.

“DEF” must not come into contact with skin, eyes or clothing.
- If the “DEF” comes into contact with your eyes or skin, rinse affected areas with clean water immediately.
- If the “DEF” is swallowed, immediately rinse your mouth out with a lot of clean water and drink plenty of water.
- Change clothing that is soiled with “DEF” immediately.
- If allergic reactions occur, consult a doctor immediately.
Keep the “DEF” out of the reach of children.

IMPORTANT
t
The “DEF” lines and all connected components are pressurised during operation and could be hot, even after the engine has been switched off. There is a risk of burns.
When opening the pressurised system, there is a risk of scalding due to hot “DEF” spraying out.
- Wait at least 5 minutes after switching off the engine before starting to work on the exhaust gas after-treatment system.
- Open line connections and caps on system components slowly. Cover the area that you are disconnecting with a cloth.
- Wear suitable protective gloves, protective clothing and safety goggles.
If the “DEF” gets into the coolant circuit (even minute amounts), thermostats and temperature sensors will be damaged.
- Always keep the “DEF” completely separate from other service products.
- Do not use the same containers and fluid collecting pans for the “DEF” and other service products.
- Do not continue to use service products that contain traces of “DEF”.
Individual components of the SCR system react very sensitively to even the slightest trace of impurities in the “DEF”.
- Only use containers and fluid collecting pans that are clean and suitable for the “DEF”.
- Do not continue to use “DEF” which contains traces of impurities.

Fire fighting measures
The “DEF” is not flammable. In the event of a fire, NH3 (ammonia) may be released.
This may result in a risk of poisoning. Measures to extinguish a fire must therefore be adapted to suit the surroundings.
