Changing 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
section. 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.
WARNING
-
California proposition 65
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 con-
tact 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 handling used oil.
ENGINE COOLANT
WARNING - Cooling fan
Use caution when
working near the
blade of the cooling
fan. The electric
motor (cooling fan) is
controlled by engine coolant
temperature, refrigerant pres-
sure and vehicle speed. It may
sometimes operate even when
the engine is not running.
Your vehicle equipped with GDI,
the electric motor (cooling fan)
may operate until you discon-
nect the negative battery cable.
Not heeding these warnings
could result in serious injuries.

Maintenance
Checking the coolant level
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 F (Full) and L (Low) marks
on the side of the coolant reservoir
when the engine is cool.
If the coolant level is low, add enough
specified coolant to provide protection
against freezing and corrosion. Bring
the level to F (Full), but do not overfill.
If frequent additions are required, see
an authorized HYUNDAI dealer for a
cooling system inspection.
Recommended engine coolant
When adding coolant, use onlydeionized water or soft water for
your vehicle and never mix hard
water in the coolant filled at the fac-
tory. An improper coolant mixture
can result in serious malfunction or
engine damage.
The engine in your vehicle has alu- minum engine parts and must be
protected by an ethylene-glycol-
based coolant to prevent corrosion
and freezing.
DO NOT USE alcohol or methanol coolant or mix them with the spec-
ified coolant.
Do not use a solution that contains more than 60% antifreeze or less
than 35% antifreeze, which would
reduce the effectiveness of the
solution. For mixture percentage, refer to the
following table.

Maintenance
BRAKE FLUID
Checking the brake fluid level
Check the fluid level in the reservoir
periodically. The fluid level should be
between MAX (Maximum) and MIN
(Minimum) marks on the side of the
reservoir.
Before removing the reservoir cap
and adding brake fluid, clean the
area around the reservoir cap thor-
oughly to prevent brake fluid contam-
ination.If the level is low, add fluid to the
MAX (Maximum) level. The level will
fall with accumulated mileage. This is
a normal condition associated with
the wear of brake linings. If the fluid
level is excessively low, have the
brake system checked by an author-
ized HYUNDAI dealer.
Use only the specified brake fluid.
(Refer to “Recommended lubricantsor capacities” in section 8.)
Never mix different types of fluid.
In the event the brake system
requires frequent additions of fluid,
the vehicle should be inspected by
an authorized HYUNDAI dealer.
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.
OVG079007L
CAUTION - Proper fluid
Only use brake fluid in brakesystem. Small amounts ofimproper fluids (such as engineoil) can cause damage to thebrake system.
CAUTION - Brake fluid
Do not allow brake fluid to con-tact the vehicle's body paint, aspaint damage will result.
WARNING - Brake fluid
When changing and adding
brake fluid, handle it carefully.
Do not let it come in contact with
your eyes. If brake fluid should
come in contact with your eyes,
immediately flush them with a
large quantity of fresh tap water.
Have your eyes examined by a
doctor as soon as possible.

Battery recharging
Your vehicle has a maintenance-free,
calcium-based battery.
If the battery becomes discharged
in 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. When recharging the battery, observe
the following precautions:
The battery must be removed from
the vehicle and placed in an area
with good ventilation.
Watch the battery during charging, and stop or reduce the charging
rate if the battery cells begin
gassing (boiling) violently or if the
temperature of the electrolyte of
any cell exceeds 120°F (49°C).
Wear eye protection when check- ing the battery during charging.
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 the positive battery terminal.
Before performing maintenance or recharging the battery, turn off all
accessories and stop the engine.
The negative battery cable must be removed first and installed last
when the battery is disconnected.
Reset items
Items should be reset after the bat-
tery has been discharged or the bat-
tery has been disconnected.

FUSES
A vehicle’s electrical system is pro-
tected from electrical overload dam-
age by fuses.
This vehicle has 2 fuse panels, one
located in the driver’s side panel bol-
ster, another is in the engine com-
partment.
If any of your vehicle’s lights, acces-
sories, or controls do not work, check
the appropriate circuit fuse. If a fuse
has blown, the element inside the
fuse will be melted.
If the electrical system does not work,
first check the driver’s side fuse panel.
Before replacing a blown fuse, dis-
connect 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 and imme-
diately consult an authorized
HYUNDAI dealer.
Three kinds of fuses are used: bladetype for lower amperage rating, car-tridge type, and multi fuse type forhigher amperage ratings.

WARNING - Fuse
replacement
Never replace a fuse with any- thing but another fuse of the
same rating.
A higher capacity fuse could cause damage and possibly a
fire.
Never install a wire or alu- minum foil instead of the
proper fuse - even as a tem-
porary repair. It may cause
extensive wiring damage and
a possible fire.
CAUTION - Fuse
replacement
Do not use a screwdriver or anyother metal object to removefuses because it may cause ashort circuit and damage thesystem.

Instrument panel fuse replace-
ment
1. Turn the ignition switch and all
other switches off.
2. Open the fuse panel cover. 3. Pull the suspected fuse straight out.
Use the removal tool provided in the
engine compartment fuse panel.
4. Check the removed fuse; replace it if it is blown.
5. Push in a new fuse of the same rat- ing, and make sure it fits tightly in
the clips.
If it fits loosely, consult an authorized
HYUNDAI dealer.
If you do not have a spare, use a fuse of the same rating from a circuit youmay not need for operating the vehicle,such as the power outlet fuse.
If the headlights or other electrical
components do not work and the
fuses are OK, check the fuse panel in
the engine compartment. If a fuse is
blown, it must be replaced.

CAUTION
When replacing a blown fuse
or relay with a new one, makesure the new fuse or relay fitstightly into the clips Theincomplete fastening fuse orrelay may cause the vehiclewiring and electric systemsdamage and a possible fire.
Do not remove fuses, relays and terminals fastened withbolts or nuts. The fuses, relaysand terminals may be fas-tened incompletely, and it maycause a possible fire. If fuses,relays and terminals fastenedwith bolts or nuts are blown,consult an authorizedHYUNDAI dealer.
Do not input any other objects except fuses or relays intofuse/relay terminals such as adriver or wiring. It may causecontact failure and systemmalfunction.
