Maintenance
Engine compartment precau-
tions (Diesel engine)
• The piezo injector operates at high
voltage (maximum 200v).
Therefore, the following accidents
may occur.
- Direct contact with the injector or
injector wiring may cause electric
shock or damage your muscle or
nerve system.
- The electromagnetic wave from
the operating injector may cause
the artificial heart pacemaker to
malfunction.
• Follow the safety tips provided
below, when you are checking the
engine room while the engine is
running.
- Do not touch the injector, injector
wirings, and the engine computer
while the engine is running.
- Do not remove the injector con-
nector while the engine is run-
ning.
- People using pacemakers must
not go near the engine while the
engine is starting or running.
WARNING- Diesel Engine
Never work on injection system
with engine running or within 30
seconds after shutting off
engine. High-pressure pump,
rail, injectors and high-pressure
pipes are subject to high pres-
sure even after the engine
stopped. The fuel jet produced
by fuel leaks may cause serious
injury, if it touches the body.
People using pacemakers
should not move than 30cm
closer to the ECU or wiring har-
ness within the engine room
while engine is running, since
the high currents in the elec-
tronic engine control system
produce considerable magnetic
fields.(Continued)
• When you remove the interior
trim cover with a flat head (-)
driver, be careful not to dam-
age the cover.
• Be careful when you replace
and clean bulbs to avoid
burns or electrical shock.

EXPLANATION OF SCHEDULED MAINTENANCE ITEMS
Engine oil and filter
The engine oil and filter should be
changed at the intervals specified in
the maintenance schedule. If the car
is being driven in severe conditions,
more frequent oil and filter changes
are required.
Drive belts
Inspect all drive belts for evidence of
cuts, cracks, excessive wear or oil
saturation and replace if necessary.
Drive belts should be checked peri-
odically for proper tension and
adjusted as necessary.
Fuel filter (cartridge)
A clogged filter can limit the speed at
which the vehicle may be driven,
damage the emission system and
cause multiple issues such as hard
starting. If an excessive amount of
foreign matter accumulates in the
fuel tank, the filter may require
replacement more frequently.
After installing a new filter, run the
engine for several minutes, and
check for leaks at the connections.
We recommend that the fuel filter be
replaced by an authoized HYUNDAI
dealer.
Fuel lines, fuel hoses and con-
nections
Check the fuel lines, fuel hoses and
connections for leakage and dam-
age. We recommend that the fuel
lines, fuel hoses and connectionsr be
replaced by an authoized HYUNDAI
dealer.
WARNING - Diesel only
Never work on injection system
with engine running or within 30
seconds after shutting off
engine. High pressure pump,
rail, injectors and high pressure
pipes are subject to high pres-
sure even after the engine
stopped. The fuel jet produced
by fuel leaks may cause serious
injury, if it touch the body.
People using pacemakers
should not move than 30cm
closer to the ECU or wiring har-
ness within the engine room
while engine is running, since
the high currents in the
Common Rail system produce
considerable magnetic fields.
CAUTION
When you are inspecting the
belt, place the ignition switch in
the LOCK/OFF or ACC position.

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.
Three kinds of fuses are used: blade
type for lower amperage rating, car-
tridge type, and multi fuse for higher
amperage ratings.✽NOTICE
The actual fuse/relay panel label
may differ from equipped items.
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 prop-
er fuse - even as a temporary
repair. It may cause extensive
wiring damage and a possible
fire.
CAUTION
Do not use a screwdriver or any
other metal object to remove
fuses because it may cause a
short circuit and damage the
system.

Maintenance
Inner panel fuse replacement
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
rating, and make sure it fits tightly
in the clips.
If it fits loosely, we recommend that
you consult an authorized HYUNDAI
dealer.
If you do not have a spare, use a
fuse of the same rating from a circuit
you may not need for operating the
vehicle, such as the cigar lighter
fuse.

CAUTION
• When replacing a blown fuse
or relay with a new one, make
sure the new fuse or relay fits
tightly into the clips. The
incomplete fastening fuse or
relay may cause the vehicle
wiring and electric systems
damage and a possible fire.
• Do not remove fuses, relays
and terminals fastened with
bolts or nuts. The fuses, relays
and terminals may be fas-
tened incompletely, and it may
cause a possible fire. If fuses,
relays and terminals fastened
with bolts or nuts are blown,
we recommend that you con-
sult an authorized HYUNDAI
dealer.
• Do not input any other objects
except fuses or relays into
fuse/relay terminals such as a
driver or wiring. It may cause
contact failure and system
malfunction.

LIGHT BULBS
Use only the bulbs of the specified
wattage.
✽NOTICE
After heavy, driving rain or wash-
ing, headlight and taillight 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.WARNING - Working on
the lights
Prior to working on the light,
firmly apply the parking brake,
ensure that the ignition switch
is turned to the “LOCK” position
and turn off the lights to avoid
sudden movement of the vehi-
cle and burning your fingers or
receiving an electric shock.
CAUTION
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 headlight
assembly to get to the bulb(s).
Removing/installing the head-
light assembly can result in
damage to the vehicle.
