Maintenance
僅 Keep urea solution out of reach of
children.
僅 When urea solution overflows the
vehicle surface, wash out the surface
with clean water to prevent any corro-
sion.
僅 When replenishing, be careful lest the
urea solution should overflow.
僅 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 solu-
tion, the urea solution tank level may
not be detected correctly until the
urea solution will be defrosted by acti-
vated 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 cer-
tain temperatures. This phenomenon
may cause malfunction of the SCR
system which can lead to the prohibi-
tion of engine restarting.
僅 The time to defrost the urea solution
varies in accordance with driving con-
ditions and outside temperatures.
CAUTION
僅 If defective urea solution or unrecom-
mended liquid is supplied, damage on
car parts such as emission reduction
devices can be caused. If defective
fuel is added, foreign objects will be
accumulated to SCR catalyst and
cause it to get clogged and break.
After adding incorrect urea solution,
please visit the nearby authorised Kia
dealer/ service partner as early as
possible.
僅 Liquid that are not recommended
such as diesel, petrol, and alcohol
shall never be used other than the
recommended urea solution that sat-
isfy ISO22241 or DIN70070.
僅 If defective urea solution or liquid that
is not recommended is supplied, there
may be damage on the parts of the
vehicle such as processing device. If
defective fuel is used, foreign objects
will be accumulated to SCR catalyst
and cause catalyst pushed away or
breaking.
