Maintenance
Instrument panel fuse replace- ment
1. Turn the ignition switch and all otherswitches off.
2. Open the fuse panel cover. 3. Pull the suspected fuse straight out.
Use the removal tool provided in the fuse panel.
4. Check the removed fuse; replace it if it is blown.
Spare fuses are provided in the instru-
ment panel fuse panel (or in the enginecompartment fuse panel).
5. 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.
If you do not have a spare, use a fuse of the same rating from a circuit you maynot need for operating the vehicle, such as the cigarette lighter fuse.
If the headlights or other electrical com-
ponents do not work and the fuses are
OK, check the fuse panel in the engine
compartment. If a fuse is blown, it mustbe replaced.

Memory fuse
Your vehicle is equipped with a memory
fuse to prevent battery discharge if your
vehicle is parked without being operated
for prolonged periods. Use the following
procedures before parking the vehicle for
prolonged periods.
1. Turn off the engine.
2. Turn off the headlights and tail lights.
3. Open the driver’s side panel cover and
pull up the memory fuse.
✽✽ NOTICE
 If the memory fuse is pulled up from the fuse panel, the warning chime,
audio, clock and interior lamps, etc.,
will not operate. Some items must be
reset after replacement. Refer to
“Battery” in this section.
 Even when the memory fuse is pulled
up, the battery can still be discharged
by operation of the headlights or other
electrical devices.
Engine compartment fuse replacement
1. Turn the ignition switch and all other switches off.
2. Remove the fuse panel cover by pressing the tab and pulling the cover
up.
3. Check the removed fuse; replace it if it is blown. To remove or insert the fuse,use the fuse puller in the engine com-
partment fuse panel.
4. 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.

Maintenance
Main fuse and Multi fuse
If the main fuse and Multi fuse is blown,
it must be removed as follows:
1. Disconnect the negative battery cable.
2. Remove the nuts shown in the pictureabove.
3. Replace the fuse with a new one of the same rating.
4. Reinstall in the reverse order of removal.
✽✽ NOTICE
If the main fuse is blown, consult an
authorized HYUNDAI dealer.CAUTION
After checking the fuse panel in the engine compartment, securelyinstall the fuse panel cover. If not,
electrical failures may occur fromwater contact.

Maintenance
Canister
Fuel vapors generated inside the fuel tank are absorbed and stored in the
onboard canister. When the engine is
running, the fuel vapors absorbed in the
canister are drawn into the surge tank
through the purge control solenoid valve.
Purge Control Solenoid Valve (PCSV)
The purge control solenoid valve is con-
trolled by the Engine Control Module
(ECM); when the engine coolant temper-
ature is low during idling, the PCSV clos-
es so that evaporated 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 performance.
Vehicle modifications
This vehicle should not be modified.
Modification of your vehicle could affect
its performance, safety or durability and
may even violate governmental safety
and emissions regulations.
In addition, damage or performance
problems resulting from any modification
may not be covered under warranty.
If you use unauthorized electronicdevices, it may cause the vehicle to
operate abnormally, wire damage, bat-
tery discharge and fire. For your safety,
be careful not to damage.
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 vehicle, have it inspected and
repaired immediately. If you ever sus-
pect exhaust fumes are coming into
your vehicle, drive it only with all the
windows fully open. Have your vehicle
checked and repaired immediately.
WARNING - Exhaust
Engine exhaust gases contain car-
bon monoxide (CO). Though color-
less and odorless, it is dangerousand could be lethal if inhaled.
Follow the instructions on this
page to avoid CO poisoning.
CALIFORNIA PROPOSI-
TION 65 WARNING
Engine exhaust and a wide variety of automobile components and
parts, including components foundin the interior furnishings in a vehi-
cle, contain or emit chemicals
known to the State of California to
cause cancer and birth defects and
reproductive harm. In addition, cer-
tain fluids contained in vehicles
and certain products of component
wear contain or emit chemicals
known to the State of California to
cause cancer and birth defects or
other reproductive harm.

Specifications, Consumer information, Reporting safety defects
Recommended SAE viscosity
number Engine oil viscosity (thickness) has an
effect on fuel economy and cold weather
operating (engine start and engine oil
flowability). Lower viscosity engine oils
can provide better fuel economy and cold
weather performance, however, higher
viscosity engine oils are required for sat-
isfactory lubrication in hot weather. Using
oils of any viscosity other than those rec- ommended could result in engine dam-
age.When choosing an oil, consider the range
of temperature your vehicle will be oper-
ated in before the next oil change.Proceed to select the recommended oil
viscosity from the chart.
CAUTION
Always be sure to clean the area
around any filler plug, drain plug, or dipstick before checking or drain-
ing any lubricant. This is especiallyimportant in dusty or sandy areasand when the vehicle is used onunpaved roads. Cleaning the plug
and dipstick areas will prevent dirt and grit from entering the engineand other mechanisms that couldbe damaged.

For better fuel economy, it is recommended to use the engine oil of
a viscosity grade SAE 5W-20 (API SM / ILSAC GF-4). However, if
the engine oil is not available in your country, select the proper
engine oil using the engine oil viscosity chart.
