Maintenance
❈ 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 performance, caus-
ing various malfunctions.
❈ 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 envi-
ronmental condition)
❈ It takes some time to update the
cluster gauges after the urea solu-
tion injection.

• 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
solution, when your vehicle is
equipped with the urea solu-
tion 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 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 completely turned
OFF.

WARNING
• Do not apply any external
impact on the DPF system. It
may damage 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 sys-
tem may cause a system mal-
function. The DPF system is
controlled by a complex elec-
tronic control unit.
