Maintenance
• When urea solution overflows
the vehicle surface, wash out
the surface with clean water to
prevent any corrosion.
• When replenishing, be careful lest
the urea solution should overflow.
• In case the vehicle was parked at
very low ambient temperature
(below -11 degree Celcius) 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 detected correctly until the
urea solution will be defrosted by
activated heater. Incorrect urea
solution or diluted urea solution
can increase the freezing point,
and thus defrosting may not
be properly done by the heater
which is activated below certain
temperatures. This phenomenon
may cause malfunction of the
SCR system which can lead to the
prohibition of engine restarting.
• The time to defrost the urea
solution varies in accordance with
driving conditions and outside
temperatures.
CAUTION
• If defective urea solution or
unrecommended liquid is supplied,
damage on car parts such as
emission reduction devices can
be caused. If defective fuel is
added, foreign objects will be
8 146
accumulated to SCR catalyst
and cause it to get clogged and
break. After adding incorrect urea
solution, please visit the nearby
authorized Kia dealer/service
partner 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.
