Maintenance
* It takes some time to update the cluster
gauges after the urea solution injec-
tion.
WARNING
僅 Do not apply any external impact on
the DPF system. It may damage the
catalyst, which is equipped inside the
DPF system.
僅 Do not arbitrarily modify or manipu-
late the DPF system by redirecting or
lengthen the exhaust pipe. It may
adversely impact the DPF system.
僅 Avoid contact with drained water from
the exhaust pipe. The water is slightly
acid and harmful to skin. If contacted,
thoroughly wash it.
僅 Any arbitrary manipulation or modifi-
cation of the DPF system may cause a
system malfunction. The DPF system
is controlled by a complex electronic
control unit.
僅 Wait for the DPF system to cool down
before the maintenance service, as it
is hot due to heat generation. Other-
wise, it may cause a skin burn.
僅 Add only the specified urea solution,
when your vehicle is equipped with
the urea solution system.
僅 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 solution inside, even
after the ENGINE START/STOP button
is pressed to the OFF position. Before
the maintenance service, make sure
that the urea solution system is com-
pletely turned OFF.
僅 A urea solution of poor quality or any
unauthorised liquids may damage the
vehicle components, including the
DPF system. Any unverified additives
9 96
in the urea solution may clog the SCR
catalyst and cause other malfunc-
tions, which require the expensive
DPF system to be replaced.
僅 When urea solution comes in contact
with the eyes or the skin, you should
thoroughly wash the contaminated
skin area.
僅 When you swallow urea solution, thor-
oughly rinse your mouth and drink a
lot of fresh water. Then, immediately
consult a doctor.
僅 When your cloth is contaminated with
urea solution, immediately change
your cloth.
僅 When you have an allergic reaction to
urea solution, immediately consult a
doctor.
僅 Make sure that urea solution is kept
out of reach from children.
僅 Wipe off any urea solution spillage
with water or cloth. When urea solu-
tion is crystalized, wipe it off with a
sponge or a cloth, which was damp-
ened in cold water.
When urea solution spillage is
exposed in air for an extended period
of time, it is crystalized in white, dam-
aging the vehicle surface.
僅 Urea solution is not a fuel additive.
Thus, it should not be injected to the
fuel tank. Otherwise, it may damage
the engine.
僅 Urea solution is an aqueous solution,
which is inflammable, non-toxic,
colourless and odourless.
僅 Store the urea solution tank only in
well-ventilated locations. When urea
solution is exposed to the hot tem-
perature at approximately 50°C for an
extended period of time (i.e. under
direct sunlight), the chemical decom-
