If the air flow rate suddenly decreas-
es, we recommend the system be
checked at an authorized HYUNDAI
dealer.
It is important that the correct
type and amount of oil and refrig-
erant is used. Otherwise, damage
to the compressor and abnormal
system operation may occur.Checking the amount of air con-ditioner refrigerant and com-pressor lubricant
When the amount of refrigerant is
low, the performance of the air con-
ditioning is reduced. Overfilling also
has a bad influence on the air condi-
tioning system.
Therefore, if abnormal operation is
found, we recommend that the sys-
tem be inspected by an authorized
HYUNDAI dealer.
We recommend the air conditioning
system be serviced by an authorized
HYUNDAI dealer.
NOTICE
Vehicles equipped with R-134a
Because the refriger-
ant is at very high
pressure, the air condi-
tioning system should
only be serviced by trained and
certified technicians. It is impor-
tant that the correct type and
amount of oil and refrigerant is
used. Otherwise, it may cause
damage to the vehicle and per-
sonal inju
ry.
WARNING
Vehicles equipped with R-1234yf
Because the refriger-
ant is mildly inflamma-
ble at very high pres-
sure, the air condition-
ing system should only
be serviced by trained
and certified techni-
cians. It is important
that the correct type and amount
of oil and refrigerant is used.
Otherwise, it may cause dam-
age to the vehicle and personal
injury.

System maintenance
Climate control air filter
This filter is installed behind the
glove box. It filters the dust or other
pollutants that enter the vehicle
through the heating and air condi-
tioning system.
We recommend that the climate con-
trol air filter replaced by an author-
ized HYUNDAI dealer according to
the maintenance schedule. If the car
is being driven in severe conditions
such as dusty or rough roads, more
frequent climate control filter inspec-
tions and changes are required.
If the air flow rate suddenly decreas-
es, we recommend the system be
checked at an authorized HYUNDAI
dealer.

Maintenance
Owner maintenance schedule
When you stop for fuel:
Check the engine oil level.
Check coolant level in the enginecoolant reservoir.
Check the windshield washer fluid level.
Check for low or under-inflated tires.
While operating your vehicle:
Note any changes in the sound of the exhaust or any smell of exhaust
fumes in the vehicle.
Check for vibrations in the steering wheel. Notice if there is any
increased steering effort or loose-
ness in the steering wheel, or
change in its straight-ahead position.
Notice if your vehicle constantly turns slightly or “pulls” to one side when
traveling on smooth, level road.
When stopping, listen and check for unusual sounds, pulling to one side,
increased brake pedal travel or
“hard-to-push” brake pedal.
If any slipping or changes in the operation of your transaxle occurs,
check the transaxle fluid level.
Check the automatic transmission/ dual clutch transmission P (Park)
function.
Check the parking brake.
Check for fluid leaks under your vehicle (water dripping from the air
conditioning system during or after
use is normal).
Be careful when checking your
engine coolant level when the
engine is hot. This may result in
coolant being blown out of the
opening and cause serious
burns and other injuries.
WARNING
Diesel Engine
Never manipulate or modify the
injection system while running
the diesel engine or within 30
seconds after turning OFF the
diesel engine. The high-pressure
pump, high-pressure pipes, rail,
and injectors are still subject to
the high pressure right after
stopping the diesel engine.
When the fuel leakage vents out,
it may cause serious body injury.
Any people, who are implement-
ed with the artificial cardiac
pacemaker, should remain away
from the ECU or the wiring har-
ness by at least 30 cm, while run-
ning the diesel engine. The high
currents of the electric engine
control system produce a con-
siderable amount of magnetic
fields.

Checking the engine oil level
1. Follow all of the oil manufacturer’s
precautions.
2. Be sure the vehicle is on level ground.
3. Start the engine and allow it to reach normal operating temperature.
4. Turn the engine off and wait for a few minutes (about 5 minutes) for
the oil to return to the oil pan.
5. Pull the dipstick out, wipe it clean, and re-insert it fully. 6. Pull the dipstick out again and
check the level. The level should
be between F (Full) and L (Low). 7. If it is near or at L, add enough oil
to bring the level to F.
Use only the specified engine oil.
(Refer to “Recommended lubricants
and capacities” in chapter 8.)

Radiator hose
Be very careful not to touch the
radiator hose when checking or
adding engine oil as it may be
hot enough to burn you.
WARNING

Maintenance
To prevent damage to your engine:
Do not overfill with engine oil. Add oil in small quantities and
recheck level to ensure engine
is not overfilled.
Do not spill engine oil when adding or changing engine oil.
Use a funnel to help prevent oil
from being spilled on engine
components. Wipe off spilled oil
immediately.
Checking the engine oil and filter
We recommend that the engine oil
and filter be replaced by an authorized
HYUNDAI dealer.
NOTICE
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.

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 mileage. This is a normal condition
associated with the wear of the brake
linings. If the fluid level is excessively low,
we recommend that the system be
checked by an authorized 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.
Information
Clean 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 brake/ clutch system
parts.

OPD076016
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 authorized
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.

Maintenance
Battery recharging
By battery charger
Your vehicle has a maintenance-free,
calcium-based battery.
If the battery becomes dischargedin a short time (because, for exam-
ple, the headlights or interior lights
were left on while 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 while
the vehicle is being used, recharge
it at 20-30A for two hours. 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 place the Engine Start/
Stop button to the OFF posi-
tion.
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 chargermain 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.
