MaintenanceAfter checking the fuse box in the
engine compartment securely
close the fuse box cover inside
the engine compartment, until it
clicks.
If the fuse box is not closed prop-
erly, water may leak in side, possi-
bly causing a malfunction with the
electrical system.
Main fuse
If the main fuse is blown, it must be
removed as follows:
1. Turn off the engine.
2. Disconnect the negative battery cable.
3. Remove the fuse panel cover by pressing the tab and pulling it up.
4. Remove the nuts shown in the pic- ture above.
5. Replace the fuse with a new one of the same rating.
6. Reinstall in the reverse order of removal.
Information
If the main fuse is blown, consult an
authorized retailer of Genesis
Branded products.
Multi fuse
If the multi fuse is blown, it must be
removed as follows:
1. Turn off the engine.
2. Disconnect the negative batterycable.
3. Remove the fuse panel cover by pressing the tab and pulling it up.
4. Remove the nuts shown in the pic- ture above.
5. Replace the fuse with a new one of the same rating.
6. Reinstall in the reverse order of removal.

Consult an authorized HYUNDAI
dealer to replace most vehicle light
bulbs. 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 for removing the headlamp
assembly to get to the bulb(s).
Removing/installing the headlamp
assembly can result in damage to
the vehicle.
Information
After heavy driving, rain or washing,
headlamp and trunk lenses could
appear frosty. This condition is caused
by the temperature difference between
the lamp inside and the outside tem-
perature. This is similar to the con-
densation on your windows inside
your vehicle during the rain and does-
n't indicate a problem with your vehi-
cle. If the water leaks into the lamp
bulb circuitry, have your vehicle
checked by an authorized retailer of
Genesis Branded products.

Prior to replacing a lamp,
depress the foot brake, move
the shift lever into P (Park)
apply the parking brake, place
the Engine Start/Stop button
to the OFF position, and take
the key with you when leaving
the vehicle to avoid sudden
movement of the vehicle and
to prevent possible electric
shock.
Be aware the bulbs may be hot and may burn your fin-
gers.
WARNING
OHI076038N
Do not attempt to replace or
inspect the low/high beam
(XENON bulb) due to electric
shock danger. If the low/high
beam (XENON bulb) is not work-
ing, have your vehicle checked
by an authorized retailer of
Genesis Branded products.

Maintenance
Purge Control Solenoid Valve(PCSV)
The purge control solenoid valve is
controlled by the Engine Control
Module (ECM); when the engine
coolant temperature is low during
idling, the PCSV closes so that evap-
orated fuel is not taken into the
engine. After the engine warms-up
during ordinary driving, the PCSV
opens to introduce evaporated fuel to
the engine.
3. Exhaust Emission Control System
The Exhaust Emission Control
System is a highly effective system
which controls exhaust emissions
while maintaining good vehicle per-
formance.
When the engine starts or fails to
start, excessive attempts to restart
the engine may cause damage to the
emission system.
Engine exhaust (carbon monox-
ide) precautions
Carbon monoxide can be present
with other exhaust fumes. If you
smell exhaust fumes of any kind in
your vehicle, drive with all the win-
dows 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.
Engine exhaust gases contain
carbon monoxide (CO). Though
colorless and odorless, it is
dangerous and could be lethal if
inhaled. Follow the instructions
on this page to avoid CO poi-
soning.
WARNING
CALIFORNIA PROPOSITION 65
WARNING
Engine exhaust and a wide vari-
ety of automobile components
and parts, including compo-
nents found in the interior fur-
nishings in a vehicle, contain or
emit chemicals known to the
State of California to cause can-
cer and birth defects and repro-
ductive harm. In addition, cer-
tain fluids contained in vehicles
and certain products of compo-
nent wear contain or emit chem-
icals known to the State of
California to cause cancer and
birth defects or other reproduc-
tive harm.

Recommended SAE Viscosity Number
Always be sure to clean the area around any filler plug, drain plug, or
dipstick before checking or draining any lubricant. This is especially
important in dusty or sandy areas and when the vehicle is used on
unpaved roads. Cleaning the plug and dipstick areas will prevent dirt
and grit from entering the engine and other mechanisms that could be
damaged.
Engine oil viscosity (thickness) has an effect on fuel economy and cold weath-
er operating (engine start and engine oil flowability). Lower viscosity engine
oils can provide better fuel economy and cold weather performance, howev-
er, higher viscosity engine oils are required for satisfactory lubrication in hot
weather. Using oils of any viscosity other than those recommended could
result in engine damage. When choosing an oil, consider the range of temper-
ature your vehicle will be operated in before the next oil change. Proceed to
select the recommended oil viscosity from the chart.
NOTICE
*1: For better fuel economy, it is recommended to use the engine oilof a viscosity grade SAE 5W-20 (API SM / ILSAC GF-4
(or above)). However, if the engine oil is not available in your
country, select the proper engine oil using the engine oil viscos-
ity chart.
