• In case the vehicle was parked at
very low ambient temperature
(below 11 degree Celsius) for a
long time, the urea solution will be
frozen in the urea solution tank.
With frozen urea solution, the urea
solution tank level may not be de‐
tected correctly until the urea sol‐
ution will be defrosted by activa‐
ted heater. Incorrect urea solution
or diluted urea solution can in‐
crease the freezing point, and thus
defrosting may not be properly
done by the heater which is acti‐
vated below certain temperatures.
This phenomenon may cause mal‐
function of the SCR system which
can lead to the prohibition of en‐
gine restarting.
• The time to defrost the urea solu‐
tion varies in accordance with driv‐
ing conditions and outside temper‐
atures.
CAUTION
• If defective urea solution or liquid
that is not recommended is sup‐
plied, there may be damage on the
parts of the vehicle such as pro‐
cessing device. If defective fuel is
used, foreign objects will be accu‐
mulated to SCR catalyst and cause
catalyst pushed away or breaking.
After adding the incorrect urea
solution, please visit the closest
service centre as early as possible.
• Liquid that are not recommended
such as diesel, petrol, and alcohol
shall never be used other than the
recommended urea solution that
satisfy ISO22241 or DIN70070.
• If defective urea solution or liquid
that is not recommended is sup‐
plied, there may be damage on the
parts of the vehicle such as pro‐
cessing device. If defective fuel is
used, foreign objects will be accu‐
mulated to SCR catalyst and cause
catalyst pushed away or breaking.
