ENGINE COOLANT
Changing the engine oil and filter
Have engine oil and filter changed by a
HYUNDAI authorised repairer according
to the Maintenance Schedule. The high-pressure cooling system has a
reservoir filled with year-round antifreeze
coolant. The reservoir is filled at the fac-
tory.
Check the antifreeze protection and
coolant concentration level at least once
a year, at the beginning of the winter sea-
son, and before travelling to a colder cli-
mate.
Checking the coolant level
WARNING
- Removing
radiator cap
 Never attempt to remove the radi- ator cap whilst the engine is
operating or hot. Doing so mightlead to cooling system and
engine damage and could result
in serious personal injury fromescaping hot coolant or steam.

WARNING
Prolonged and repeated contact
with used engine oils may result in
serious skin disorders including
dermatitis and cancer. Avoid con-
tact with skin as far as possible and
always wash thoroughly after any
contact. Keep used oils out of
reach of children. It is illegal to pol-
lute drains, water courses and soil.
Use only authorised waste collec-
tion facilities including civic ameni-
ty sites and garages for the dispos-
al of used oil and oil filters. If in
doubt, contact the local authority
for disposal instructions.

Check the condition and connections of all cooling system hoses and heater
hoses. Replace any swollen or deterio-
rated hoses.
The coolant level should be filled
between F (MAX) and L (MIN) marks on
the side of the coolant reservoir when theengine is cool.
If the coolant level is low, add enough
specified coolant to provide protection
against freezing and corrosion. Bring the
level to F (MAX), but do not overfill. If fre-quent coolant refill is required, see a
HYUNDAI authorised repairer for a cool-ing system inspection.
Recommended engine coolant
 Use only soft (de-mineralized) water in
the coolant mixture.
 The engine in your vehicle has alu- minum engine parts and must be pro-
tected by an ethylene-glycol-based
coolant to prevent corrosion and freez-ing.
 DO NOT USE alcohol or methanol coolant or mix them with the specifiedcoolant.
 Do not use a solution that contains more than 60% antifreeze or less than
35% antifreeze, which would reduce
the effectiveness of the solution.

 Turn the engine off and wait untilit cools down. Use extreme care
when removing the radiator cap.
Wrap a thick towel around it, and
turn it counterclockwise slowly to
the first stop. Step back whilst
the pressure is released from the
cooling system. When you aresure all the pressure has been
released, press down on the cap,
using a thick towel, and continue
turning counterclockwise to
remove it.
 Even if the engine is not operat- ing, do not remove the radiatorcap or the drain plug whilst the
engine and radiator are hot. Hot
coolant and steam may still blow
out under pressure, causing seri-
ous injury.

Maintenance
For mixture percentage, refer to the fol-
lowing table.Changing the coolant
Have coolant changed by a HYUNDAI
authorised repairer according to the
Maintenance Schedule.
WARNING -
Radiator cap
Do not remove the radiator cap when the engine and radiator are
hot. Scalding hot coolant and
steam may blow out under pres-
sure causing serious injury.
CAUTION
Put a thick cloth or fabric around the radiator cap before refilling the
coolant in order to prevent the coolant from overflowing into engine parts such as generator.
WARNING - Coolant
 Do not use radiator coolant or antifreeze in the washer fluid
reservoir.
 Radiator coolant can severely obscure visibility when sprayed
on the windscreen and may
cause loss of vehicle control or
damage to paint and body trim.

BRAKE/CLUTCH FLUID
Checking the brake fluid level
Check the fluid level in the reservoir peri-
odically. The fluid level should be
between MAX and MIN marks on the
side of the reservoir. Before removing the reservoir cap and
adding brake fluid, clean the area around
the reservoir cap thoroughly to prevent
brake fluid contamination.
If the level is low, add fluid to the MAX
level. The level will fall with accumulated
mileage. This is a normal condition asso-
ciated with the wear of the brake linings.
If the fluid level is excessively low, have
the brake system checked by a
HYUNDAI authorised repairer.
Use only the specified brake fluid. (Refer
to “Recommended lubricants and capac-ities” in section 8.)
Never mix different types of fluid.
WARNING - Brake fluid
When changing and adding brake
fluid, handle it carefully. Do not let it
come in contact with your eyes. Ifbrake fluid should come in contact
with your eyes, immediately flush
them with a large quantity of fresh
tap water. Have your eyes examined
by a doctor as soon as possible.
WARNING - Loss of brake fluid
In the event the brake system
requires frequent additions of fluid,
the vehicle should be inspected by
a HYUNDAI authorised repairer.
CAUTION
Do not allow brake fluid to contact the vehicle's body paint, as paint
damage will result. Brake fluid,which has been exposed to open air for an extended time should neverbe used as its quality cannot be
guaranteed. It should be disposed of properly. Don't put in the wrongkind of fluid. A few drops of miner-al-based oil, such as engine oil, in
your brake system can damagebrake system parts.

FUEL FILTER (FOR DIESEL)
Draining water from fuel filter
The fuel filter for diesel engine plays an
important role of separating water from
fuel and accumulating the water in itsbottom.
If water accumulates in the fuel filter, the
warning light comes on when the ignition
switch is in the ON position. If this warning light illuminates,
take your car to a HYUNDAI
authorised repairer and have
drain the water and checkedthe system. Fuel filter cartridge replacement
✽✽NOTICE
When replacing the fuel filter cartridge, use HYUNDAI genuine parts.
OLM079011
CAUTION
If the water accumulated in the fuel filter is not drained at proper times,
damages to the major parts such asthe fuel system can be caused by water permeation in the fuel filter.

Replace the filter according to the
Maintenance Schedule.
If the vehicle is operated in extremely
dusty or sandy areas, replace the ele-ment more often than the usual recom-
mended intervals.
CAUTION
 Do not drive with the air cleaner removed; this will result in exces-
sive engine wear.
 When removing the air cleaner fil- ter, be careful that dust or dirtdoes not enter the air intake, or
damage may result.
 Use a HYUNDAI genuine part. Use of nongenuine part could damagethe air flow sensor or turbo charg-er.

Maintenance
Battery recharging
Your vehicle has a maintenance-free,
calcium-based battery.
 If the battery becomes discharged in ashort time (because, for example, the
headlights or interior lights were left on
whilst the vehicle was not in use),
recharge it by slow charging (trickle)
for 10 hours.
 If the battery gradually discharges because of high electric load whilst the
vehicle is being used, recharge it at 20-
30A for two hours.(Continued)
 When lifting a plastic-cased bat-tery, excessive pressure on the
case may cause battery acid to
leak, resulting in personal injury.
Lift with a battery carrier or with
your hands on opposite corners.
 Never attempt to recharge the battery when the battery cablesare connected.
 The electrical ignition system works with high voltage. Never
touch these components with theengine running or the ignition
switched on.
Failure to follow the above warn-
ings can result in serious bodily
injury or death.WARNING - Recharging
battery
When recharging the battery,
observe the following precautions:
 The battery must be removed from the vehicle and placed in an area with good ventilation.
 Do not allow cigarettes, sparks, or flame near the battery.
 Watch the battery during charg- ing, and stop or reduce the charg-
ing rate if the battery cells begin
gassing (boiling) violently or if
the temperature of the electrolyte
of any cell exceeds 49°C (120°F).
 Wear eye protection when check- ing the battery during charging.
