ENGINE COOLANT
Changing the engine oil and filterWe recommend that the engine oil and
filter be replaced by a HYUNDAI autho-
rised repairer. 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.
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.
CAUTION
 When the engine overheats from
low engine coolant, suddenlyadding engine coolant may causecracks in the engine. To prevent damage, add engine coolantslowly in small quantities.
 Do not drive with no engine coolant. It may cause water pumpfailure and engine seizure, etc.

Maintenance
Checking the coolant level
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 the
engine 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, we rec-
ommend that the system be inspected by
a HYUNDAI authorised repairer.

(Continued)
 Even if the engine is not operat-ing, do not remove the radiator
cap 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.
WARNING
The electric motor (cool-
ing fan) is controlled by
engine coolant tempera-
ture, refrigerant pres-
sure and vehicle speed.
It may sometimes operate even
when the engine is not running.
Use extreme caution when working
near the blades of the cooling fan
so that you are not injured by a
rotating fan blades. As the engine
coolant temperature decreases, the
electric motor will automatically
shut off. This is a normal condition.
If your vehicle is equipped with
GDI, the electric motor (cooling fan)
may operate until you disconnect
the nagative battery cable.
WARNING
Removing radiator
cap
 Never attempt to remove the radi- ator cap whilst the engine is
operating or hot. Doing so might
lead to cooling system and
engine damage and could result
in serious personal injury from
escaping hot coolant or steam.
 Turn the engine off and wait until it 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 sys-
tem. When you are sure all the
pressure has been released,
press down on the cap, using a
thick towel, and continue turning
counterclockwise to remove it.

7Recommended engine coolant When adding coolant, use only deion-
ized water or soft water for your vehicle
and never mix hard water in the
coolant filled at the factory. An improp-
er coolant mixture can result in serious
malfunction or engine damage.
 The engine in your vehicle has alumini- um engine parts and must be protected
by an ethylene-glycol-based coolant to
prevent corrosion and freezing.
 DO NOT USE alcohol or methanol coolant or mix them with the specified
coolant.
 Do not use a solution that contains more than 60% antifreeze or less than
35% antifreeze, which would reduce
the effectiveness of the solution.
For mixture percentage, refer to the fol-
lowing table.
Changing the coolantWe recommend that the coolant be
replaced by a HYUNDAI authorised
repairer.
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 thecoolant from overflowing intoengine parts such as generator.
WARNING -
Coolant
 Do not use radiator coolant or anti -
freeze 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 (IF EQUIPPED)Checking the brake/clutch fluid
level Check the fluid level in the reservoir peri-
odically. The fluid level should be
between MAX (Maximum) and MIN
(Minimum) 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
(Maximum) level. The level will fall with
accumulated mileage. This is a normal
condition associated with the wear of the
brake linings and/or clutch disc (if
equipped).If the fluid level is excessively low, we
recommend that the brake system be
checked by a HYUNDAI authorised
repairer.
Use only the specified brake/clutch fluid.
(Refer to “Recommended lubricants or capacities” in section 8.)
Never mix different types of fluid.✽ ✽ NOTICEBefore removing the brake/clutch filler
cap, read the warning on the cap.
WARNING -
Loss of brake
fluid
In the event the brake system
requires frequent additions of fluid,
we recommend that the system be
inspected by a HYUNDAI autho-
rised repairer.
OLM079008R
WARNING
Clean filler cap before removing.
Use only DOT3 or DOT4 brake/
clutch fluid from a sealed container.
WARNING -
Brake/clutch
fluid
When changing and adding
brake/clutch fluid, handle it careful-
ly. Do not let it come in contact with
your eyes. If brake/clutch fluid
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.
CAUTION
Do not allow brake/clutch fluid to
contact the vehicle's body paint, aspaint damage will result.
Brake/clutch fluid, which has beenexposed to open air for an extended time should never be used as itsquality cannot be guaranteed. Itshould be properly disposed. Don't put in the wrong kind of fluid. A fewdrops of mineral-based oil, such asengine oil, in your brake/clutch sys- tem can damage brake/clutch sys-tem parts.

7WASHER FLUIDChecking the washer fluid level Check the fluid level in the washer fluid
reservoir and add fluid if necessary.
Plain water may be used if washer fluid is
not available. However, use washer sol-
vent with antifreeze characteristics in
cold climates to prevent freezing.
Check the parking brakeCheck the stroke of the parking brake by
counting the number of “clicks’’ heard
whilst fully applying it from the released
position. Also, the parking brake alone
should securely hold the vehicle on a fair-
ly steep grade. If the stroke is more or
less than specified, we recommend that
the system be checked by a HYUNDAI
authorised repairer.
Stroke : 6 “clicks’’ at a force of
44 lbs (20 kg, 196 N).
WARNING -
Coolant
 Do not use radiator coolant orantifreeze 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.
 Windscreen Washer fluid agents contain some amounts of alcohol
and can be flammable under cer-
tain circumstances. Do not allow
sparks or flame to contact the
washer fluid or the washer fluid
reservoir. Damage to the vehicle
or occupants could occur.
 Windscreen washer fluid is poi- sonous to humans and animals.
Do not drink and avoid contact-
ing windscreen washer fluid.
Serious injury or death could
occur.

FUEL FILTER (FOR DIESEL)Draining water from fuel filterThe fuel filter for diesel engine plays an
important role of separating water from
fuel and accumulating the water in its
bottom.
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,
we recommend that the sys-
tem by checked by a HYUNDAI
authorised repairer.
Extracting air from the fuel filterIf you drive until you have no fuel left or if
you replace the fuel filter, be sure to
extract air from the fuel system as it
makes it difficult to start the engine.
1. Pump up and down(1) approximately50 times until the pump is hard.
2. Extract air from the fuel filter by remov- ing the bolt(2) with a cross-tip screw
driver and reinstall the bolt(2).
3. Pump up and down(1) approximately 15 times.
4. Extract air from the fuel filter by remov- ing the bolt(2) with a cross-tip screw
driver and reinstall the bolt(2).
5. Pump up and down(1) approximately 5 times.
✽ ✽NOTICE• Use cloths when you extract air so that
the fuel is not sprayed around.
• Clean the fuel around the fuel filter or the injection pump before starting the
engine to prevent fire.
• Finally, check each part if the fuel is leaking.
CAUTION
If the water accumulated in the fuel
filter is not drained at proper times,damages to the major parts such as the fuel system can be caused bywater permeation in the fuel filter.
