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.
WARNING

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

Maintenance
AGM battery (if equipped)
Absorbent Glass Matt (AGM)
batteries are maintenance-
free and we recommend that
the AGM battery be serviced
by an authorised HYUNDAI
dealer. For charging your
AGM battery, use only fully
automatic battery chargers
that are specially developed
for AGM batteries.
When replacing the AGM bat-
tery, we recommend that you
use parts for replacement
from an authorised HYUNDAI
dealer.
Do not open or remove the
cap on top of the battery. This
may cause leaks of internal
electrolyte that could result in
severe injury.
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
area with plenty of ventilation.
Wear eye protection when
checking the battery during
charging.
The battery must be removed
from the vehicle and placed in
a well ventilated area.
(Continued)
WARNING (Continued)
Watch the battery during
charging, and stop or reduce
the charging rate if the battery
cells begin boiling violently.
The negative battery cable
must be removed first and
installed last when the battery
is disconnected. Disconnect
the battery charger in the fol-
lowing order:
(1) Turn off the battery charger
main switch.
(2) Unhook the negative
clamp from the negative
battery terminal.
(3) Unhook the positive clamp
from the positive battery
terminal.
Always use a genuine HYUNDAI
approved battery when you
replace the battery.

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
Keep paint and trim in good condition
Scratches or chips in the finish
should be covered with "touch-up"
paint as soon as possible to reduce
the possibility of corrosion. If bare
metal is showing through, the atten-
tion of a qualified body and paint
shop is recommended.
Bird droppings : Bird droppings are
highly corrosive and may damage
painted surfaces in just a few hours.
Always remove bird droppings as
soon as possible.
Don't neglect the interior
Moisture can collect under the floor
mats and carpeting to cause corro-
sion. Check under the mats periodi-
cally to be sure the carpeting is dry.
Use particular care if you carry fer-
tilisers, cleaning materials or chemi-
cals in the vehicle.
These should be carried only in
proper containers and any spills or
leaks should be cleaned up, flushed
with clean water and thoroughly
dried.
Interior care
Interior general precautions
Prevent chemicals such as perfume,
cosmetic oil, sun cream, hand clean-
er and air freshener from contacting
the interior parts because they may
cause damage or discolouration. If
they do contact the interior parts,
wipe them off immediately.
See the instructions that follow for
the proper way to clean vinyl.
Never allow water or other liquids to
come in contact with electrical/elec-
tronic components inside the vehi-
cle as this may damage them.
When cleaning leather products
(steering wheel, seats etc.), use
neutral detergents or low alcohol
content solutions. If you use high
alcohol content solutions or acid/
alkaline detergents, the colour of
the leather may fade or the sur-
face may get stripped off.
Cleaning the upholstery and
interior trim
Vinyl (if equipped)
Remove dust and loose dirt from
vinyl with a whisk broom or vacuum
cleaner. Clean vinyl surfaces with a
vinyl cleaner.
Fabric (if equipped)
Remove dust and loose dirt from fabric
with a whisk broom or vacuum cleaner.
Clean with a mild soap solution recom-
mended for upholstery or carpets.
Remove fresh spots immediately with
a fabric spot cleaner. If fresh spots do
not receive immediate attention, the
fabric can be stained and its colour can
be affected. Also, its fire-resistant prop-
erties can be reduced if the material is
not properly maintained.
Using anything but recommended
cleaners and procedures may affect
the fabric’s appearance and fire-
resistant properties.

Refer to “Fuel Requirements” in the Introduction chapter.
Always be sure to clean the area around any filler plug, drain plug, or dipstick before checking or draining
any lubricant. This is especially important in dusty or sandy areas and when the vehicle is used on unpaved
roads. Cleaning the plug and dipstick areas will prevent dirt and grit from entering the engine and other
mechanisms that could be damaged.
CAUTION
Recommended SAE viscosity number
Engine oil viscosity (thickness) has an effect on fuel economy and cold weather operating (engine start and engine
oil flowability). Lower viscosity engine oils can provide better fuel economy and cold weather performance, however,
higher viscosity engine oils are required for satisfactory lubrication in hot weather. Using oils of any viscosity other
than those recommended could result in engine damage.
