ENGINE OIL
Checking the Engine Oil Level
Engine oil is used for lubricating,
cooling, and operating various hydraulic
components in the engine. Engine oil
consumption while driving is normal,
and it is necessary to check and refill the
engine oil regularly. Also, check and refill
the oil level within the recommended
maintenance schedule to prevent
deterioration of oil performance.
Check the engine oil following the below
procedure.
Gasoline engine
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 and the wheels blocked.
3. Turn the engine on and warm
the engine up until the coolant
temperature reaches a constant
normal temperature.
4. Turn the engine off, remove the oil
filler cap and pull the dipstick out.
Wait for 15 minutes for the oil to return
to the oil pan.
5. Wipe the dipstick clean and re-insert
it fully.

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 while you break in a new
vehicle and it will be stabilized after
driving 4,000 miles (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.
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 the maintenance schedule to
replace engine oil is exceeded,
the engine oil performance may
deteriorate, and the engine condition
may be affected. Therefore, replace
the engine oil according to the
maintenance schedule.
• To keep the engine in optimal
condition, use the recommended
engine oil and filter. If the
recommended engine oil and filter are
not used, replace it according to the
maintenance schedule under severe
usage conditions.
• The purpose of the maintenance
schedule for engine oil replacement
is to prevent oil deterioration and it is
irrelevant to oil consumption. Check
and refill engine oil regularly.

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 traveling to a colder climate.
Checking the Coolant Level
ONX4OB091019ONX4OB091019
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 the MAX and the MIN marks on
the side of the coolant reservoir when
the engine is cool.
If the coolant level is low, add enough
distilled (deionized) water to bring the
level to the MAX mark, but do not overfill.
If frequent additions are required, see an
authorized HYUNDAI dealer for a cooling
system inspection.
WARNING
Never remove the engine
coolant cap and/or water-
cooled intercooler coolant
cap or the drain plug while
the engine and radiator are
hot. Hot coolant and steam
may blow out under pressure,
causing serious injury.
Turn the vehicle off and wait until the
engine cools down. Use extreme care
when removing the engine coolant cap.
Wrap a thick towel around it, and turn
it counterclockwise slowly to the first
stop. Step back while 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
counterclockwise to remove it.
Information
The coolant level is influenced by the
engine temperature. Before checking or
refilling the coolant, turn the engine off.

WARNING
The electric motor for the cooling fan
may continue to operate or start up
when the engine is not running and
can cause serious injury. Keep hands,
clothing and tools away from the
rotating fan blades of the cooling fan.
Always turn off the vehicle unless the
vehicle has to be inspected with the
engine on. Be cautious as the cooling
fan may operate if the negative (-)
battery terminal is not disconnected.
WARNING
Make sure the coolant cap is properly
closed after refilling coolant. Otherwise
the engine could be overheated while
driving.

Checking the Brake Fluid Level
ONX4OB091020ONX4OB091020
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 the specified brake
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, have the brake system
be checked by an authorized HYUNDAI
dealer.
WARNING
If the brake system requires frequent
additions of fluid this could indicate a
leak in the brake system. Have that the
vehicle be inspected by an authorized
HYUNDAI dealer.
WARNING
Do not allow brake fluid to come in
contact with your eyes. If brake 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 fluid to contact
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
disposed of properly.
• Do not use the wrong kind of brake
fluid. A few drops of mineral 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” section in chapter 2).

WASHER FLUID
Checking the Washer Fluid Level
ONX4OB091021ONX4OB091021
Check the fluid level in the washer fluid
reservoir and add fluid if necessary.
Plain water may be used during summer
months 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 flame 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.

Your vehicle has a maintenance-free,
calcium-based battery.
• If the battery becomes discharged
over a short time (because, for
example, the headlamps 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 electrical load while
the vehicle is being used, recharge it
at 20-30A for two hours.
WARNING
Always follow these instructions when
recharging your vehicle’s battery to
avoid the risk of SERIOUS INJURY or
DEATH from explosions or acid burns:
• Before performing maintenance or
recharging the battery, turn off all

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.
• 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
following order:
1. Turn off the battery charger main
switch.
2. Unhook the negative clamp from
the negative battery terminal.
3. Unhook the positive clamp from

A vehicle’s electrical system is protected
from electrical overload damage by
fuses.
This vehicle has 5 fuse panels, one
located in the driver’s side panel bolster,
the other in the engine compartment.
If any of your vehicle’s lights,
accessories, or controls do not work,
check the appropriate circuit fuse. If a
fuse has blown, the element inside the
fuse will be melted or broken.
If the electrical system does not work,
first check the driver’s side fuse panel.
Before replacing a blown fuse, turn the
engine and all switches off, and then
disconnect the negative battery cable.
Always replace a blown fuse with one of
the same rating.
If the replacement fuse blows, this
indicates an electrical problem. Avoid
using the system involved. Immediately
consult an authorized HYUNDAI dealer.
WARNING
NEVER replace a fuse with anything but
another fuse of the same rating.
• A higher capacity fuse could cause
damage and possibly cause a fire.
• Do not install a wire or aluminum
foil instead of the proper fuse -
even as a temporary repair. It may
cause extensive wiring damage and
possibly a fire.
NOTICE
Do not use a screwdriver or any other
metal object to remove fuses because
it may cause a short circuit and damage
the system.
