minium, copper, copper alloy, non-
alloyed still, and galvanized steel).
The urea solution dissolves the
metal materials, severely damag-
ing the exhaust purification system
to be non-repairable.
• Store the urea solution only in the
containers made with the following
materials.
(DIN EN 10 088-1-/-2-/-3-specified
CR-Ni steel, Mo-Cr-Ni
polypropylene, and polyethylene)

- Additives are mixed in the urea
solution.
- Water is added to dilute the urea

• When any unauthorised impurities
enter the urea solution tank, it may
occur the following problems.
- Increased emission
- Malfunction with the DPF system
- Engine failure
Never add the used urea solution,
which is drained from the tank (i.e.
whilst maintaining the vehicle). Its
purity cannot be guaranteed. Always
add the new urea solution.
