Brake hoses and lines
Visually check for proper installation,
chafing, cracks, deterioration and
any leakage. Replace any deteriorat-
ed or damaged parts immediately.
Brake fluid
Check brake fluid level in the brake
fluid reservoir. The level should be
between “MIN” (Minimum) and
“MAX” (Maximum) marks on the side
of the reservoir. Use only hydraulic
brake fluid conforming to DOT 3 or
DOT 4 specification.
Parking brake
Inspect the parking brake system
including the parking brake lever and
cables.
Brake discs, pads, calipers
and rotors
Check the pads for excessive wear,
discs for run out and wear, and
calipers for fluid leakage.
For more information on checking
the pads or lining wear limit, refer to
the Hyundai web site.

Suspension mounting bolts
Check the suspension connections
for looseness or damage. Retighten
to the specified torque.
Steering gear box, linkage &
boots/lower arm ball joint
With the vehicle stopped and engine
off, check for excessive free-play in
the steering wheel.
Check the linkage for bends or dam-
age. Check the dust boots and ball
joints for deterioration, cracks, or
damage. Replace any damaged
parts.
Drive shafts and boots
Check the drive shafts, boots and
clamps for cracks, deterioration, or
damage. Replace any damaged
parts and, if necessary, repack the
grease.
Air conditioning refrigerant
(if equipped)
Check the air conditioning lines and
connections for leakage and dam-
age.

ENGINE OIL
Checking the engine oil level
1. Ensure the vehicle is on level
ground.
2. Start the engine and allow it to
reach normal operating tempera-
ture.
3. Turn the engine off and wait for a
few minutes (about 5 minutes) for
the oil to return to the oil pan.
4. Pull the dipstick out, wipe it clean,
and reinsert it fully.5. Pull the dipstick out again and
check the level. The level should
be between F (Full) and L (Low).
WARNING - Radiator
hose
Be very careful not to touch the
radiator hose when checking or
adding the engine oil as it may
be hot enough to burn you.CAUTION
• Do not spill engine oil, when
adding or changing engine oil.
If you spill engine oil in the
engine compartment, wipe it
off immediately.
• When you wipe the oil level
gauge, you should wipe it with
a clean cloth. When mixed
with debris, it can cause
engine damage.

Maintenance
24 7
If it is near or at L (Low), add enough
oil to bring the level to F (Full).Do
not overfill.
Use a funnel to help prevent oil
from being spilt on engine compo-
nents.
Use only the specified engine oil.
(Refer to “Recommended lubricants
and capacities” in section 8.)
Changing the engine oil and
filter
We recommend that the engine oil
and filter be replaced by an autho-
rised HYUNDAI dealer.
CAUTION
Do not overfill the engine oil. It
may damage the engine.

Maintenance
WARNING
Used engine oil may cause skin
irritation or cancer if left in con-
tact with the skin for prolonged
periods of time. Used engine oil
contains chemicals that have
caused cancer in laboratory
animals. Always protect your
skin by washing your hands
thoroughly with soap and warm
water as soon as possible after
handling used oil.

ENGINE COOLANT
The high-pressure cooling system
has a reservoir filled with year-round
antifreeze coolant. The reservoir is
filled at the factory.
Check the antifreeze protection and
coolant level at least once a year, at
the beginning of the winter season,
and before travelling to a colder cli-
mate.Checking the coolant level(Continued)
• 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
anticlockwise slowly to the
first stop. Step back whilst the
pressure is released from the
cooling system. When you are
sure all the pressure has been
released, press down on the
cap, using a thick towel, and
continue turning anticlock-
wise to remove it.
• Even if the engine is not oper-
ating, do not remove the radi-
ator 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 injuries.
WARNING
Removing radiator
cap
• Never attempt to remove the
radiator 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.
(Continued)
CAUTION
• Do not drive with no engine
coolant. It may cause water
pump failure and engine
seizure, etc.
• When the engine overheats
from low engine coolant, sud-
denly adding engine coolant
may cause cracks in the
engine. To prevent damage,
add engine coolant slowly in
small quantities.

727
Maintenance
Check the condition and connections
of all cooling system hoses and
heater hoses. Replace any swollen
or deteriorated hoses.
The coolant level should be filled
between F (Full) and L (Low)
marked on the side of the coolant
reservoir when the engine is cool.
If the coolant level is low, add enough
distilled (deionized) water. Bring the
level to F (Full), but do not overfill. If
frequent additions are required, we
recommend that the system be
inspected by an authorised
HYUNDAI dealer.
Recommended engine coolant
• Use only soft (distilled) water in the
coolant mixture.
• The engine in your vehicle has alu-
minium 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 spec-
ified 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
following table.WARNING
The electric motor
(cooling fan) is con-
trolled by engine
coolant temperature,
refrigerant pressure
and vehicle speed. It may some-
times 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.

Changing the coolant
We recommend that the coolant be
replaced by an authorised HYUNDAI
dealer.
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 injuries.
OMD071005L
CAUTION
Put a thick cloth or fabric
around the radiator cap before
refilling the coolant in order to
prevent the coolant from over-
flowing into engine parts such
as the alternator.
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.

Maintenance
BRAKE/CLUTCH FLUID (IF EQUIPPED)
Checking the brake/clutch
fluid level
Check the fluid level in the reservoir
periodically. The fluid level should be
between MAX (Maximum) and MIN
(Minimum) marks on the side of the
reservoir. Before removing the reser-
voir 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 kilometres/
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 system be
checked by an authorised HYUNDAI
dealer.
Use only the specified brake/clutch
fluid. (Refer to “Recommended lubri-
cants or capacities” in section 8.)
Never mix different types of fluid.
✽NOTICE
Before 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 an
authorised HYUNDAI dealer.
WARNING - Brake/clutch
fluid
When changing and adding
brake/clutch fluid, handle it care-
fully. Do not let it come in contact
with your eyes. If brake/clutch
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.
CAUTION
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 proper-
ly disposed. 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 brake/clutch
system parts.
OMD071006R
WARNING
Clean filler cap before remov-
ing. Use only DOT3 or DOT4
brake/clutch fluid from a sealed
container.
