Vacuum crankcase ventilation
hoses (if equipped)
Inspect the surface of hoses for
evidence of heat and/or mechanical
damage. Hard and brittle rubber,
cracking, tears, cuts, abrasions, and
excessive swelling indicate deterioration.
Particular attention should be paid to
examine those hose surfaces nearest to
high heat sources, such as the exhaust
manifold.
Inspect the hose routing to assure that
the hoses do not come in contact with
any heat source, sharp edges or moving
component which might cause heat
damage or mechanical wear. Inspect
all hose connections, such as clamps
and couplings, to make sure they are
secure, and that no leaks are present.
Hoses should be replaced immediately if
there is any evidence of deterioration or
damage.
Air cleaner filter
We recommend that the air cleaner filter
be replaced by a HYUNDAI authorised
repairer.
Spark plugs
(for petrol engine)
Make sure to install new spark plugs of
the correct heat range.
When assembling parts, be sure to
wipe out foreign substances inside
and outside of the boot bottom of the
ignition coil and the insulator of the
spark plug with a soft cloth to prevent
contamination of the spark plug
insulator.
WARNING
Do not disconnect and inspect spark
plugs when the engine is hot. You may
burn yourself.
Cooling system
Check the cooling system parts, such
as radiator, coolant reservoir, hoses and
connections for leakage and damage.
Replace any damaged parts.
Engine coolant
The coolant should be changed at the
intervals specified in the maintenance
schedule.
Manual transmission fluid/iMT
system actuator fluid
(if equipped)
Inspect the Manual transmission fluid/
iMT system actuator fluid according to
the maintenance schedule.
Automatic transmission fluid
(if equipped)
Automatic transmission fluid should
not be checked under normal usage
conditions.
We recommend that the automatic
transmission fluid is changed by a
HYUNDAI authorised repairer according
to the maintenance schedule.

of the reservoir. Use only hydraulic
brake/clutch fluid conforming to DOT 4
specification.
Parking brake
Inspect the parking brake system
including the parking brake lever and
cables.
Rear brake drums and linings
(if equipped)
Check the rear brake drums and linings
for scoring, burning, leaking fluid,
broken parts, and excessive wear.
% U D N H S D G V F D O L S H U V D Q G U R W R U V
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 damage.

7. If the oil level is below the L, add
enough oil to bring the level to F.
Use only the specified engine oil (Refer
to “Recommended Lubricants and
Capacities” section in chapter 2).
NOTICE
To prevent damage to your engine:
[ Do not spill engine oil when adding or
changing engine oil. Wipe off spilled
oil immediately.
[ The engine oil consumption may
increase whilst you break in a new
vehicle and it will be stabilized after
driving 6,000 km (4,000 miles).
[ The engine oil consumption can be
affected by driving habits, climate
conditions, traffic conditions,
oil quality, etc. Therefore, it is
recommended that you inspect the
engine oil level regularly and refill it if
necessary.

which is highly corrosive. Do
not allow acid to contact your
eyes, skin or clothing.
If acid gets into your eyes, flush your
eyes with clean water for at least 15
minutes and get immediate medical
attention. If acid gets on your skin,
thoroughly wash the area. If you
feel pain or a burning sensation, get
medical attention immediately.
[ When lifting a plastic-cased battery,
excessive pressure on the case may
cause battery acid to leak. Lift with a
battery carrier or with your hands on
opposite corners.
[ Do not attempt to jump start your
vehicle if your battery is frozen.
[ NEVER attempt to recharge the
battery when the vehicle’s battery
cables are connected to the battery.
[ The electrical ignition system works
with high voltage. NEVER touch these
components with the engine running
or when the Engine Start/Stop button
is in the ON position.
[ Do not allow the (+) and (-) jumper
cables to touch. It may cause sparks.
[ The battery may rupture or explode
when you jump start with a low or
frozen battery.
[ Leaked battery electrolyte due to
repeated driving on sharp curves
(e.g. on circuits) may cause safety
problem. Avoid repeated driving on
sharp curves.
NOTICE
If you connect unauthorised electronic
devices to the battery, the battery may
be discharged. Never use unauthorised
devices.

WARNING
[ Handle halogen bulbs with care.
Halogen bulbs contain pressurized
gas that will produce flying pieces
of glass that could cause injuries if
broken.
[ Wear eye protection when changing
a bulb. Allow the bulb to cool down
before handling it.
[ Always handle them carefully, and
avoid scratches and abrasions. If
the bulbs are lit, avoid contact with
liquids.
[ Never touch the glass with bare
hands. Residual oil may cause the bulb
to overheat and burst when lit.
[ A bulb should be operated only when
installed in a headlight.
[ If a bulb becomes damaged or
cracked, replace it immediately and
carefully dispose of it.

The low beam light distribution is
asymmetric. If you go abroad to a
country with opposite traffic direction,
this asymmetric part will dazzle
oncoming car driver. To prevent dazzle,
ECE regulation demands several
technical solutions (ex. automatic
change system, adhesive sheet, down
aiming). This headlamps are designed
not to dazzle opposite drivers.
So, you need not change your
headlamps in a country with the
opposite traffic direction.

Maintenance
NOTICE
If you park your vehicle near a stainless
steel sign or glass facade building, the
vehicle’s exterior plastic parts such
as a bumper, spoiler, garnish, lamp
or outside rearview mirror might be
damaged due to sunlight reflected
from the sign or building. To prevent
damage of the exterior plastic parts,
you should avoid parking in areas
where light may be reflected or use a
car cover. (The exterior plastic parts
applied to your vehicle may vary.)
Exterior care
Exterior general caution
It is very important to follow the label
directions when using any chemical
cleaner or polish. Read all warning and
caution statements that appear on the
label.
Finish maintenance
: D V K L Q J
To help protect your vehicle’s finish
from rust and deterioration, wash it
thoroughly and frequently at least once
a month with lukewarm or cold water.
If you use your vehicle for off-road driving,
you should wash it after each off-road trip.
Pay special attention to the removal of any
accumulation of salt, dirt, mud, and other
foreign materials. Make sure the drain
holes in the lower edges of the doors and
rocker panels are kept clear and clean.
Insects, tar, tree sap, bird droppings,
industrial pollution and similar deposits
can damage your vehicle’s finish if not
removed immediately.
Even prompt washing with plain water
may not completely remove all these
deposits.
A mild soap, safe for use on painted
surfaces, may be used.
After washing, rinse the vehicle
thoroughly with lukewarm or cold water.
Do not allow soap to dry on the finish.
