8. If it is near or at L, add enough oil
to bring the level to F. Do not over-
fill.
Use only the specified engine oil.
(Refer to “Recommended lubricants
and capacities” in chapter 8.)
Checking the engine oil and filter
We recommend that the engine oil
and filter be replaced by an authorised
HYUNDAI dealer.
Used engine oil may cause irri-
tation or cancer of the skin if
left in contact with the skin for
prolonged periods of time. Used
engine oil contains chemicals
that have caused cancer in lab-
oratory animals. Always protect
your skin by washing your
hands thoroughly with soap
and warm water as soon as pos-
sible after handling used oil.

Checking the brake/clutch
fluid level
Check the fluid level in the reservoir
periodically. The fluid level should be
between MAX and MIN marks on the
side of the reservoir.
Before removing the reservoir cap
and adding brake/clutch fluid, clean
the area around the reservoir cap
thoroughly to prevent brake/clutch
fluid contamination.
If the level is low, add fluid to the MAX
level. The level will fall with accumulat-
ed kilometres. This is a normal condi-
tion associated with the wear of the
brake linings.If the fluid level is excessively low,
we recommend that the system be
checked by an authorised HYUNDAI
dealer.
Information
Use only the specified brake/clutch
fluid. Refer to Recommended lubri-
cants and capacities in chapter 8.
Information
Before removing the brake/clutch filler
cap, read the warning on the cap (if
equipped).
Information
Clean the filler cap before removing.
Use only DOT3 or DOT4 brake/clutch
fluid from a sealed container. Do not allow brake/clutch fluid
to contact the vehicle's body
paint, as paint damage will
result.
Brake/clutch fluid, which has
been exposed to open air for an
extended time should never be
used as its quality cannot be
guaranteed. It should be dis-
posed of properly.
Don't put in the wrong kind of
fluid. A few drops of mineral-
based oil, such as engine oil, in
your brake/clutch system can
damage system parts.
NOTICE

OPD077016R
If the brake/clutch system
requires frequent additions of
fluid this could indicate a leak in
the brake/clutch system. We
recommend that the vehicle be
inspected by an authorised
HYUNDAI dealer.
WARNING
Do not allow brake/clutch fluid
to come in contact with your
eyes. If brake/clutch fluid comes
in contact with your eyes, flush
your eyes with clean water for at
least 15 minutes and get imme-
diate medical attention.

Draining water from fuel filter
The fuel filter in the diesel engine
operates the critical function of sepa-
rating water from the fuels and pre-
venting accumulating of water in the
base.
When enough water has accumulat-
ed inside the fuel filter, the warning
light ( ) illuminates with the igni-
tion switch in the ON position.
In this case, we recommend you to
have the system checked by an
authorised HYUNDAI dealer.
When the accumulated water is not
drained at the proper timing, water
may permeate in the fuel filter,
damaging the major vehicle com-
ponents, such as the fuel system.
Fuel filter cartridge replace-
ment
We recommend the fuel filter car-
tridge be replaced by an authorised
HYUNDAI dealer according to the
Maintenance Schedule at the begin-
ning of this chapter.
Filter replacement
The air cleaner filter can be cleaned
for inspection using compressed air.
Do not attempt to wash or to rinse it,
as water will damage the filter.
If soiled, the air cleaner filter must be
replaced.NOTICE

CAUTION
Always follow these instructions
when recharging your vehicle’s
battery to avoid the risk of SERI-
OUS INJURY or DEATH from
explosions or acid burns:
Before performing mainte-
nance or recharging the bat-
tery, turn off all accessories
and stop the engine.
Keep all flames, sparks, or
smoking materials away from
the battery.
Always work outdoors or in an

A vehicle’s electrical system is pro-
tected from electrical overload dam-
age by fuses.
This vehicle has 2 (or 3) fuse panels,
one located in the driver’s side panel
bolster, the other in the engine com-
partment.
If any of your vehicle’s lights, acces-
sories, or controls do not work, check
the appropriate circuit fuse. If a fuse
has blown, the element inside the
fuse will be melted or broken.
If the electrical system does not
work, first check the driver’s side
fuse panel. Before replacing a blown
fuse, turn the engine and all switches
off, and then disconnect the negative
battery cable. Always replace a
blown fuse with one of the same rat-
ing.
If the replacement fuse blows, this indi-
cates an electrical problem. Avoid
using the system involved and immedi-
ately consult an authorised HYUNDAI
dealer.Information
Three kinds of fuses are used: blade
type for lower amperage rating, car-
tridge type, and multi fuse for higher
amperage ratings.
Do not use a screwdriver or any
other metal object to remove
fuses because it may cause a
short circuit and damage the sys-
tem.

NEVER replace a fuse with
anything but another fuse of
the same rating.
A higher capacity fuse could
cause damage and possibly
cause a fire.
Do not install a wire or alu-
minium foil instead of the
proper fuse - even as a tem-
porary repair. It may cause
extensive wiring damage and
possibly a fire.

Maintenance
High-pressure washing
When using high-pressure washers,
make sure to maintain sufficient dis-
tance from the vehicle.
Insufficient clearance or excessive
pressure can lead to component
damage or water penetration.
Do not spray the camera, sensors or
its surrounding area directly with a
high pressure washer. Shock
applied from high pressure water
may cause the device to not operate
normally.
Do not bring the nozzle tip close to
boots (rubber or plastic covers) or
connectors as they may be dam-
aged if they come into contact with
high pressure water. Water washing in the engine com-
partment including high pressure
water washing may cause the fail-
ure of electrical circuits located in
the engine compartment.
Never allow water or other liquids
to come in contact with electri-
cal/electronic components inside
the vehicle as this may damage
them.Matte paint finish vehicle
Automatic car wash which uses
rotating brushes should not be
used as this can damage the sur-
face of your vehicle. A steam
cleaner which washes the vehicle
surface at high temperature may
result the oil to adhere and leave
stains that is difficult to remove.
Use a soft cloth (e.g. microfiber
towel or sponge) when washing
your vehicle and dry with a
microfiber towel. When you hand
wash your vehicle, you should not
use a cleaner that finishes with
wax. If the vehicle surface is too
dirty (sand, dirt, dust, contami-
nant, etc.), clean the surface with
water before washing the vehicle.

Waxing
A good coat of wax is a barrier
between your paint and contami-
nants. Keeping a good coat of wax
on your vehicle will help protect it.
Wax the vehicle when water will no
longer bead on the paint.
Always wash and dry the vehicle
before waxing. Use a good quality
liquid or paste wax, and follow the
manufacturer’s instructions. Wax all
metal trim to protect it and to main-
tain its luster.
Removing oil, tar, and similar materi-
als with a spot remover will usually
strip the wax from the finish. Be sure
to re-wax these areas even if the rest
of the vehicle does not yet need wax-
ing. Wiping dust or dirt off the body
with 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 anodised aluminium parts.
This may result in damage to the
protective coating and cause dis-
colouration or paint deteriora-
tion.
Matte paint finish vehicle
Do not use any polish protector
such as a detergent, an abrasive
and a polish. In case wax is
applied, remove the wax immedi-
ately using a silicon remover and
if any tar or tar contaminant is on
the surface use a tar remover to
clean. However, be careful not to
apply too much pressure on the
painted area.
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.
Matte paint finish vehicle
In case of matte paint finish vehi-
cles, it is impossible to modify only
the damaged area and repair of the
whole part is necessary. If the vehi-
cle is damaged and painting is
required, we recommend that you
have your vehicle maintained and
repaired by an authorised
HYUNDAI dealer. Take extreme
care, as it is difficult to restore the
quality after the repair.
