Maintenance
When urea solution overflows the
vehicle surface, wash out the sur -
face 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 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 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 pro -
hibition of engine restarting.
The time to defrost the urea
solution varies in accordance with
driving conditions and outside
temperatures.
Emission control system
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 accumu -
lated to SCR catalyst and cause it
to get clogged and break.
After adding incorrect urea solu -
tion, please visit the nearby
authorised 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.
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
processing device. If defective fuel
is used, foreign objects will be
accumulated to SCR catalyst and
cause catalyst pushed away or
breaking.
