In case the vehicle was
parked at very low ambient
temperature (below 11 dgree
Celcius) for a long time, the
urea solution will be frozen in
the urea solution tank. With
frozen urea, the tank level may
not be detected correctly until
the urea solution will be
defrosted by activated heater.
Incorrect urea or diluted urea
can increase the freezing
point, and thus defrosting
may not be properly done by
the heater which is activated

This phenomenon may cause
malfunction of the SCR sys-
tem which can lead to the pro-
hibition of engine restarting.
