Recommended SAE Viscosity
Number
CAUTION
Always be sure to clean the area around
any filler plug, drain plug, or dipstick
before checking or draining any
lubricant. This is especially important
in dusty or sandy areas and when the
vehicle is used on unpaved roads.
Cleaning the plug and dipstick areas
will prevent dirt and grit from entering
the engine and other mechanisms that
could be damaged.Engine oil viscosity (thickness) has an
effect on fuel economy and cold weather
operating (engine start and engine oil
flowability). Lower viscosity engine oils
can provide better fuel economy and
cold weather performance, however,
higher viscosity engine oils are required
for satisfactory lubrication in hot
weather.
Using oils of any viscosity other than
those recommended could result in
engine damage.
When choosing an oil, consider the
range of temperature your vehicle will be
operated in before the next oil change.
Proceed to select the recommended oil
viscosity from the chart.

Checking the amount of air
conditioner refrigerant and
compressor lubricant
When the amount of refrigerant is low,
the performance of the air conditioning
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.
NOTICE
It is important that the correct type and
amount of oil and refrigerant are used.
Otherwise, damage to the compressor
and abnormal system operation may
occur. To prevent damage, the air
conditioning system in your vehicle
should only be serviced by trained and
certified technicians.
WARNING
Vehicles equipped with R-1234yf
Since the refrigerant is
mildly flammable and
operated at high pressure,
the air conditioning system
should only be serviced
by trained and certified
technicians. It is important
that the correct type
and amount of oil and
refrigerant are used.
All refrigerants should be reclaimed
with proper equipment.
Venting refrigerants directly to the
atmosphere is harmful to individuals
and environment. Failure to heed these
warnings can lead to serious injuries.
OCN7H050001
Air conditioning refrigerant label
You can find out which air conditioning
refrigerant is applied to your vehicle on
the label located inside of the hood.

WARNING
Performing maintenance work on a
vehicle can be dangerous. If you lack
sufficient knowledge and experience or
the proper tools and equipment to do
the work, have it done by an authorized
HYUNDAI dealer.
ALWAYS follow these precautions for
performing maintenance work:
• Park your vehicle on level ground,
move the shift button into the P
(Park) position, place the ignition
switch in the LOCK/OFF position.
• Block the tires (front and back) to

Checking the Engine Oil Level
Engine oil is used for lubrication and
cooling, so it is gradually consumed
during driving the vehicle.
Regularly check and manage the oil level
using the following procedure.
1. Follow all of the oil manufacturer’s
precautions.
2. Be sure the vehicle is on the level
ground in P (Park) with the parking
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 15
minutes (with oil filler cap and dipstick
detached) for the oil to return to the
oil pan.
5. Pull the dipstick out, wipe it clean, and
re-insert it fully.
OCN7H090003
6. Pull the dipstick out again and check
the level.
OCN7H090004
7. Check if the oil level is between the
F-L line and refill it if the oil level is

NOTICE
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.
• The engine oil consumption may
increase while you break in a new
vehicle and it will be stabilized after
driving 6,000 km.
• 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.
• The engine oil change interval is
set for the purpose of preventing
oil deterioration, and is not related
the amount of oil consumption; so,
check and refill the amount of the oil
regularly.
Checking the Engine Oil and
Filter
Have engine oil and filter changed by an authorized HYUNDAI dealer according
to the Maintenance Schedule at the
beginning of this chapter.
• If exceeding the maintenance
schedule for replacement of engine
oil, the engine oil performance
may deteriorate and the engine
condition may be affected. Therefore,
the replacement cycle should be
observed.
• To keep the engine in optimal
condition, use recommended engine
oil. If not using the recommended
oil, replace it according to the severe
usage maintenance conditions.
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 prolonged periods of time.
Always protect your skin by washing
your hands thoroughly with soap and
warm water as soon as possible after

Checking the Brake/Clutch Fluid
Level
OCN7H090010
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 fluid, clean the area around
the reservoir cap thoroughly to prevent
brake fluid contamination.
If the level is low, add fluid to the MAX
level. The level will fall with accumulated
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 lubricants and
capacities” in chapter 2.
Information
Before removing the brake/clutch filler
cap, read the warning on the cap.
Information
Clean the filler cap before removing. Use
only DOT4 brake/clutch fluid from a
sealed container.
WARNING
Do not allow brake 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 immediate
medical attention.
NOTICE
• 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 disposed of properly.
• Don’t put in the wrong kind of fluid. A
few drops of mineralbased oil, such
as engine oil, in your brake system
can damage system parts.
• To maintain the best braking
performance and ABS/ESC
performance, we recommend that
you use genuine brake/clutch fluid
that conform to specifications.

Checking the Washer Fluid Level
OCN7080007
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 solvent
with antifreeze characteristics in cold
climates to prevent freezing.
WARNING
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 control 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 alcohol 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.
