Maintenance
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 (MAX) and L (MIN) marks
on the side of the coolant reservoir
when the engine is cool.
If the coolant level is low, add enough
distilled (deionized) or soft water.
Bring the level to F (MAX), but do not
overfill.
If frequent additions are required, we
recommend that the system be
inspected by an authorized HYUNDAI
dealer.
Recommended engine coolant
• When adding coolant, use only
deionized 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.
ODH073004
The electric motor
(cooling fan) is con-
trolled by engine
coolant temperature,
refrigerant pressure
and vehicle speed. It may some-
times operate even when the
engine is not running. Use
extreme caution when working
near the blades of the cooling
fan so that you are not injured
by a rotating fan blades. As the
engine coolant temperature
decreases, the electric motor
will automatically shut off. This
is a normal condition.
The electric motor (cooling fan)
may operate until you discon-
nect the negative battery cable.

FUSES
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.
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.
Four kinds of fuses are used: blade
type for lower amperage rating, car-
tridge type, multi fuse and fusible link
for higher amperage ratings.
✽NOTICE
The actual fuse/relay panel label
may differ from equipped items.
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
cause a fire.
•Never install a wire or alu-
minum foil instead of the prop-
er fuse - even as a temporary
repair. It may cause extensive
wiring damage and a possible
fire.
WARNING
Do not use a screwdriver or any
other metal object to remove
fuses because it may cause a
short circuit and damage the
system.

LIGHT BULBS
Use only the bulbs of the specified
wattage.
✽NOTICE
After heavy driving, rain or wash-
ing, headlamp and tail lamp lenses
could appear frosty. This condition
is caused by the temperature differ-
ence between the lamp inside and
outside. This is similar to the con-
densation on your windows inside
your vehicle during the rain and
doesn’t indicate a problem with
your vehicle. If the water leaks into
the lamp bulb circuitry, we recom-
mend that the system be checked by
an authorized HYUNDAI dealer.
❈Traffic Change (For Europe)
The low beam light distribution is
asymmetric. If you go abroad to a
country with opposite traffic direc-
tion, this asymmetric part will dazzle
oncoming car driver. To prevent daz-
zle, ECE regulation demand several
technical solutions (ex. automatic
change system, adhesive sheet,
down aiming). These headlamps are
designed not to dazzle opposite driv-
ers. So, you need not change your
headlamps in a country with oppo-
site traffic direction. Be sure to replace the burned-
out bulb with one of the same
wattage rating. Otherwise, it
may cause damage to the fuse
or electric wiring system.
CAUTION
If you don’t have necessary
tools, the correct bulbs and the
expertise, consult an authorized
HYUNDAI dealer. In many cases,
it is difficult to replace vehicle
light bulbs because other parts
of the vehicle must be removed
before you can get to the bulb.
This is especially true if you
have to remove the headlamp
assembly to get to the bulb(s).
Removing/installing the head-
lamp assembly can result in
damage to the vehicle.
CAUTION
Working on the lights
Prior to working on the light, firm-
ly apply the parking brake,
ensure that the Engine Start/Stop
button is turned to the OFF posi-
tion and turn off the lights to
avoid sudden movement of the
vehicle and burning your fingers
or receiving an electric shock.

✽NOTICE
HID lamps have superior perform-
ance vs. halogen bulbs.
HID lamps are estimated by the
manufacturer to last twice as long or
longer than halogen bulbs depend-
ing on their frequency of use. They
will probably require replacement
at some point in the life of the vehi-
cle. Cycling the headlamps on and
off more than typical use will short-
en HID lamps life. HID lamps do not
fail in the same manner as halogen
incandescent lamps. If a headlamp
goes out after a period of operation
but will immediately relight when
the headlamp switch is cycled it is
likely the HID lamp needs to be
replaced. HID lighting components
are more complex than conventional
halogen bulbs thus have higher
replacement cost.
✽NOTICE
We recommend that the headlamp
aiming be adjusted after an accident
or after the headlamp assembly is
reinstalled at an authorized
HYUNDAI dealer.

System is a highly effective system
which controls exhaust emissions
while maintaining good vehicle per-
formance.
Vehicle modifications
This vehicle should not be modified.
Modification of your vehicle could
affect its performance, safety or
durability and may even violate gov-
ernmental safety and emissions reg-
ulations.
In addition, damage or performance
problems resulting from any modifi-
cation may not be covered under

Engine exhaust gas precautions
(carbon monoxide)
• Carbon monoxide can be present
with other exhaust fumes.
Therefore, if you smell exhaust
fumes of any kind inside your vehi-
cle, have it inspected and repaired
immediately. If you ever suspect
exhaust fumes are coming into
your vehicle, drive it only with all
the windows fully open. Have your
vehicle checked and repaired
immediately.• Do not operate the engine in con-
fined or closed areas (such as
garages) any more than what is
necessary to move the vehicle in or
out of the area.
• When the vehicle is stopped in an
open area for more than a short
time with the engine running,
adjust the ventilation system (as
needed) to draw outside air into the
vehicle.
• Never sit in a parked or stopped
vehicle for any extended time with
the engine running.
• When the engine stalls or fails to
start, excessive attempts to restart
the engine may cause damage to
the emission control system. Exhaust
Engine exhaust gases contain
carbon monoxide (CO). Though
colorless and odorless, it is
dangerous and could be lethal if
inhaled. Follow the instructions
following to avoid CO poison-
ing.
