Maintenance
* Pay great caution not to add the
urea solution into the fuel tank.
If not, it surely applies adverse
impact on the vehicle perfor -
mance, causing various mal -
functions.
* Pay great caution not to overfill
the (completely) filled urea solu -
tion tank by force whilst refilling
urea solution from a refill bottle.
An over-filled urea solution tank
will be expanded when it
becomes frozen and this can
cause a serious malfunction of
the urea solution tank or urea
solution system.
* Never use urea solution mixture
with additives or water. It may
allow foreign substances to
enter the urea solution tank. If
so, it surely applies adverse
impact on the vehicle perfor -
mance, causing various mal -
functions.
* Use only the ISO 22241-speci -
fied urea solution. Any unautho -
rised urea solution surely applies
adverse impacts on the vehicle
performance, causing various
malfunctions.
4. Turn the urea solution tank cap in
a clockwise direction to securely
close it.
Adding urea solution: Every approxi -
mately 5,600 km (The urea solution
consumption is dependent on the
road profile, driving pattern and
environmental condition)

* It takes some time to update the
cluster gauges after the urea
solution injection.
WARNING
Do not apply any external impact
on the DPF system. It may dam -
age the catalyst, which is
equipped inside the DPF system.
Do not arbitrarily modify or
manipulate the DPF system by
redirecting or lengthen the
exhaust pipe. It may adversely
impact the DPF system.
Avoid contact with drained water
from the exhaust pipe. The water
is slightly acid and harmful to skin.
If contacted, thoroughly wash it.
Any arbitrary manipulation or
modification of the DPF system
may cause a system malfunction.
The DPF system is controlled by a
complex electronic control unit.
Wait for the DPF system to cool
down before the maintenance
service, as it is hot due to heat
generation. Otherwise, it may
cause a skin burn.
Add only the specified urea solu -
tion, when your vehicle is
equipped with the urea solution
system.
The urea solution system (i.e.
urea solution nozzle, urea solution
pump, and DCU) operates for
approximately 2 minutes more to
eliminate the remaining urea
