Checking the amount of air conditioner refrigerant andcompressor lubricant
When the amount of refrigerant is
low, the performance of the air con-
ditioning is reduced. Overfilling also
reduces the performance of the air
conditioning system.
Therefore, if abnormal operation is
found, have the system inspected by
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. The air conditioning system should
be serviced by an authorized
HYUNDAI dealer.
Air conditioning refrigerant label
The actual Air Conditioning refriger-
ant label in the vehicle may differ
from the illustration.
Each symbols and specification on
air conditioning refrigerant label
means as below :
1. Classification of refrigerant
2. Amount of refrigerant
3. Classification of Compressor lubri-
cant
Refer to chapter 8 for more detail
location of the air conditioning refrig-
erant label.
NOTICE
Because the refriger-
ant is at very high
pressure, the air con-
ditioning system
should only be serv-
iced by trained and certified
technicians. It is important that
the correct type and amount of
oil and refrigerant is used, oth-
erwise damage to the vehicle
and personal injury may occur.

How to Disconnect the (-)
Cable for Regular Maintenance
(Hybrid vehicle)
When the vehicle is under regular
maintenance, make sure to separate
the (-) cable before maintenance.
Separate the (-) cable following the
below instructions.
1. Fold the rear left side seat.
2. Remove the service cover (A) onthe luggage trim.
3. Separate the (-) cable (B).
Reassemble in the reverse order.
Owner Maintenance Schedule
When you stop for fuel:
• Check the engine oil level.
Check the coolant level in the engine coolant reservoir.
Check the windshield washer fluid level.
Check for low or under-inflated tires.
While operating your vehicle:
Note any changes in the sound ofthe 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 posi-
tion.
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 transmission
occurs, check the transmission
fluid level.
Check the 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/inverter 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.

Checking the Engine Oil Level
1. Follow all of the oil manufacturer’s
precautions.
2. Be sure the vehicle is on the level ground in P (Park) with the park-
ing brake set. If possible, block the
wheels.
3. Turn the engine on and allow the engine to reach normal operating
temperature.
4. Turn the engine off and wait about five 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. 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.

an authorized HYUNDAI dealer
according to the Maintenance
Schedule at the beginning of this
chapter.
i
The electric motor for
the cooling fan may
continue to operate

blades of the cooling fan.
WARNING
CALIFORNIA PROPOSITION 65
WARNING
Engine oil contains chemicals
known to the State of California
to cause cancer, birth defects
and reproductive harm. Used
engine oil may cause irritation
or cancer of the skin if left in
contact with the skin for pro-
longed periods of time. Always
protect your skin by washing
your hands thoroughly with
soap and warm water as soon
as possible after handling used
oil.

Maintenance
Do not allow brake fluid to con-tact the vehicle’s body paint, as
paint damage will result.
Brake 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.
Do not use the wrong kind of brake fluid. A few drops of miner-
al based oil, such as engine oil, in
your brake system can damage
brake system parts.
Information
Use only the specified brake fluid
(refer to "Recommended Lubricants
and Capacities" in chapter 8).
Checking the Washer Fluid
Level
Check the fluid level in the washer
fluid reservoir and add fluid if neces-
sary. Plain water may be used if
washer fluid is not available.
However, use washer solvent with
antifreeze characteristics in cold cli-
mates to prevent freezing.

To prevent serious injury or
death, take the following safety
precautions when using washer
fluid:
Do not use engine coolant or
antifreeze in the washer fluid
reservoir.
Engine coolant can severely
obscure visibility when
sprayed on the windshield and
may cause loss of vehicle con-
trol resulting in an accident or
damage to paint and body trim.
Do not allow sparks or flames
to contact the washer fluid or
the washer fluid reservoir.
Washer fluid may contain alco-
hol and can be flammable.
Do not drink washer fluid and
avoid contact with skin.
Washer fluid is harmful to
humans and animals.
Keep washer fluid away from
children and animals.

Checking the Parking Brake
Check whether the stroke is within
specification when the parking brake
pedal is depressed with 44 lb (20 kg,
196 N) of force. Also, the parking
brake alone should securely hold the
vehicle on a fairly steep grade. If the
stroke is more or less than specified,
have the parking brake adjusted by
an authorized HYUNDAI dealer.
Stroke : 4~5 notch
Filter Replacement
The air cleaner filter can be cleaned
for inspection using compressed air.
Do not attempt to wash or to rinse it,
as water will damage the filter.
If soiled, the air cleaner filter must be
replaced. 1. Loosen the air cleaner cover
attaching clips and open the
cover.
