Maintenance
Wiping dust or dirt off the bodywith a dry cloth will scratch the
finish.
Do not use steel wool, abrasive cleaners, or strong detergents
containing highly alkaline or
caustic agents on chrome-plated
or anodized aluminium parts.
This may result in damage to the
protective coating and cause dis-
colouration or paint deteriora-
tion.
Finish damage repair
Deep scratches or stone chips in the
painted surface must be repaired
promptly. Exposed metal will quickly
rust and may develop into a major
repair expense.
If your vehicle is damaged and
requires any metal repair or
replacement, be sure the body
shop applies anti-corrosion materi-
als to the parts repaired or replaced.
Bright-metal maintenance
To remove road tar and insects,use a tar remover, not a scraper or
other sharp object.
To protect the surfaces of bright- metal parts from corrosion, apply a
coating of wax or chrome preser-
vative and rub to a high luster.
During winter weather or in coastal areas, cover the bright metal parts
with a heavier coating of wax or
preservative. If necessary, coat the
parts with non-corrosive petroleum
jelly or other protective compound.
Underbody maintenance
Corrosive materials used for ice and
snow removal and dust control may
collect on the underbody. If these
materials are not removed, acceler-
ated rusting can occur on underbody
parts such as the fuel lines, frame,
floor pan and exhaust system, even
though they have been treated with
rust protection. Thoroughly flush the vehicle under-
body and wheel openings with luke-
warm or cold water once a month,
after off-road driving and at the end of
each winter. Pay special attention to
these areas because it is difficult to
see all the mud and dirt. It will do
more harm than good to wet down the
road grime without removing it. The
lower edges of doors, rocker panels,
and frame members have drain holes
that should not be allowed to clog with
dirt; trapped water in these areas can
cause rusting.
NOTICE
NOTICE
After washing the vehicle, test
the brakes whilst driving slowly
to see if they have been affected
by water. If braking performance
is impaired, dry the brakes by
applying them lightly whilst
maintaining a slow forward
speed.
WARNING
❈Never use the urea solution mix-
ture 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 perform-
ance, causing various malfunc-
tions.
❈ Use only the ISO 22241-speci-
fied urea solution. Any unautho-
rized 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 the urea solution: Every
approximately 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
injection.

Maintenance
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 the
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 the complex
device.
Wait for the DPF system to
cool down before the mainte-
nance service, as it is hot due
to the heat generation.
Otherwise, it may case 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 ignition
switch is pressed to the OFF
position. Before the mainte-
nance service, make sure that
the urea solution system is
completely turned OFF.WARNING
