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
Have engine oil and filter changed by
an authorized HYUNDAI dealer
according to the Maintenance
Schedule at the beginning of this
chapter.
NOTICE
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.

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 cli-
mate.Checking the Engine 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 the F and the L 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 F mark, 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 only dis-
tilled (deionized) water for your
vehicle and never mix hard water in
the coolant filled at the factory.
An improper coolant mixture can result in severe malfunction or
engine damage.
The engine in your vehicle has alu- minum engine parts and must be
protected by an ethylene-glycol
with phosphate based coolant to
prevent corrosion and freezing.
Do not use alcohol or methanol coolant or mix them with the spec-
ified coolant.OPD076011

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 mixing percentage, refer to the
following table:
Information
If in doubt about the mix ratio, a 50%
water and 50% antifreeze mix is the
easiest to mix together as it will be the
same quantity of each. It is suitable to
use for most temperature ranges of
- 31°F and higher.

For 1.6 T-GDI
Make sure the coolant cap is
properly closed after refilling
coolant. Otherwise the engine
could be overheated while driv-
ing.
1. Check if the coolant cap label is straight In front.

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 the specified
brake/clutch fluid to the MAX level.
The level will fall with accumulated
mileage. This is a normal condition
associated with the wear of the
brake/clutch linings. If the fluid level
is excessively low, have the brake/
clutch system checked by an author-
ized HYUNDAI dealer.
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.
Do not use the wrong kind of brake/clutch fluid. A few drops
of mineral based oil, such as
engine oil, in your brake/clutch
system can damage brake/
clutch system parts.
Information
Use only the specified brake/clutch
fluid (refer to "Recommended
Lubricants and Capacities" in chap-
ter 8).
i
NOTICE
If the brake/clutch system
requires frequent additions of
fluid this could indicate a leak in
the brake/clutch system. Have
the vehicle 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.

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.
Checking the Parking Brake
Check the stroke of the parking
brake by counting the number of
"clicks" heard while fully applying it
from the released position. 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 : 6 clicks at a force of 44

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 dam-
age 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.

A vehicle's electrical system is pro-
tected from electrical overload dam-
age by fuses.
This vehicle has 2 (or 3) fuse panels,
one located in the driver's side panel
bolster, the other in the engine com-
partment near the battery.
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 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 rat-
ing.
If the replacement fuse blows, this
indicates an electrical problem. Avoid
using the system involved and imme-
diately consult an authorized
HYUNDAI dealer. Do not use a screwdriver or any
other metal object to remove
fuses because it may cause a
short circuit and damage the sys-
tem.
NOTICE
NEVER replace a fuse with any-
thing 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 alu-
minum foil instead of the
proper fuse - even as a tem-
porary repair. It may cause
extensive wiring damage and
possibly a fire.

Instrument Panel Fuse
Replacement
1. Turn the engine off.
2. Turn all other switches OFF.
3. Open the fuse panel cover.
4. Refer to the label on the inside ofthe fuse panel cover to locate the
suspected fuse location. 5. Pull the suspected fuse straight
out. Use the removal tool provided
in the engine compartment fuse
panel.
6. Check the removed fuse; replace it if it is blown. Spare fuses are pro-
vided in the instrument panel fuse
panels (or in the engine compart-
ment fuse panel).
7. Push in a new fuse of the same rating, and make sure it fits tightly
in the clips. If it fits loosely, consult
an authorized HYUNDAI dealer. In an emergency, if you do not have
a spare fuse, use a fuse of the same
rating from a circuit you may not
need for operating the vehicle.
If the headlamps or other electrical
components do not work and the
fuses are undamaged, check the
fuse panel in the engine compart-
ment. If a fuse is blown, it must be
replaced with the same rating.

ly close the fuse box cover
inside the engine compartment,
until it clicks.
If the fuse box is not closed
properly, water may leak in side,
possibly causing a malfunction
with the electrical system.
