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,
turn the engine and all switches off,
and then disconnect the negative bat-
tery cable. Always replace a blown
fuse with one of the same rating.
If the replacement fuse blows, this indi-
cates an electrical problem. Avoid
using the system involved and immedi-
ately consult an authorized HYUNDAI
dealer.Information
Three kinds of fuses are used: blade
type for lower amperage rating, car-
tridge type and multi fuse for higher
amperage ratings.

Maintenance
Engine compartment panel fuse
replacement
1. Turn the engine off and all other
switches off.
2. Turn all the switches off.
3. Remove the fuse box cover by
pressing the tap and pulling up.
4. Check the removed fuse; replace it
if it is blown. To remove or insert
the fuse, use the fuse puller in the
engine compartment 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, we rec-
ommend that you consult an
authorized HYUNDAI dealer.After checking the fuse box in the
engine compartment, securely
install the fuse box cover. If not,
electrical failures may occur from
water leaking in.
Main fuse
If an electrical system does not oper-
ate with no blown fuse in the engine
room and inner fuse box, the main
fuse inside the battery (+) cap may
be blown.
The main fuse is heavily connected
to many other parts. In this case, we
recommend you to contact an
authorized HYUNDAI dealer.

Information
After heavy driving, rain or washing,
headlamp and tail lamp lenses could
appear frosty. This condition is caused
by the temperature difference between
the lamp inside and outside.
This is similar to the condensation on
your windows inside your vehicle dur-
ing the rain and doesn’t indicate a
problem with your vehicle. If the
water leaks into the lamp bulb circuit-
ry, we recommend that the system be
checked by an authorized HYUNDAI
dealer.
Information(For Europe)
The low beam light distribution is
asymmetric. If you go abroad to a
country with opposite traffic direction,
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 drivers. So, you
need not change your headlamps in a
country with opposite traffic direction.

9. Install the headlamp bulb cover by
turning it clockwise.
Information
The headlamp aiming should be
adjusted after an accident or after the
headlamp assembly is reinstalled at an
authorized HYUNDAI dealer.
Turn signal lamp
1. Open the hood.
2. Disconnect the negative battery
cable.
3.Remove the socket from the
assembly by turning the socket
counterclockwise until the tabs on
the socket align with the slots on
the assembly.
4.Remove the bulb from the socket
by pressing it in and rotating it
counterclockwise until the tabs on
the bulb align with the slots in the
socket. Pull the bulb out of the
socket.5.Insert a new bulb by inserting it into
the socket and rotating it until it
locks into place.

by aligning the tabs on the socket
with the slots in the assembly.

HID Headlamp (Type C Low)
If the HID lamp does not operate, we
recommend that the system be
checked by an authorized HYUNDAI
dealer.Information
HID lamps have superior perform-
ance vs. halogen bulbs.
HID lamps are estimated by the man-
ufacturer to last twice as long or
longer than halogen bulbs depending
on their frequency of use. They will
probably require replacement at some
point in the life of the vehicle. Cycling
the headlamps on and off more than
typical use will shorten 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 immedi-
ately relight when the headlamp
switch is cycled it is likely the HID
lamp needs to be replaced. HID light-
ing components are more complex
than conventional halogen bulbs thus
have higher replacement cost.
Turn signal lamp
1. Open the hood.
2. Disconnect the negative battery
cable.
3.Remove the socket from the
assembly by turning the socket
counterclockwise until the tabs on
the socket align with the slots on
the assembly.
4.Remove the bulb from the socket
by pressing it in and rotating it
counterclockwise until the tabs on
the bulb align with the slots in the
socket. Pull the bulb out of the
socket.

HID Headlight low beam
(if equipped)
Do not attempt to replace or
inspect the low beam (XENON
bulb) due to electric shock dan-
ger. If the low beam (XENON
bulb) is not working, we recom-
mend that the system be
checked by an authorized
HYUNDAI dealer.

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 sole-
noid valve.
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.
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
warranty.
• If you use unauthorized electronic
devices, it may cause the vehicle to
operate abnormally, wire damage,
battery discharge and fire. For your
safety, do not use unauthorized
electronic devices.
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.

Maintenance
The Malfunction Indicator Lamp (MIL)
stops illuminating, when the driving
speed exceeds 60 km/h (37mph), or
when the engine rpm is between
1,500 and 2,500 with the gear in the
2nd position or above for approxi-
mately 25 minutes.
When the MIL continuously blinks or
the warning message “Check exhaust
system” illuminates in the above
cases, we recommend you to have the
DPF system checked by an author-
ized HYUNDAI dealer.
When the vehicle is continuously driv-
en with the MIL flashing for an extend-
ed period of time, it may damage the
DPF system and lower the fuel econ-
omy.Lean NOx Trap (if equipped)
The Lean NOx Trap (LNT) system
removes the nitrogen oxide in the
exhaust gas. The smell can occur in
the exhaust gas depending on the
quality of the fuel and it can degrade
NOx reduction performance, please
use the regulated automotive diesel
fuel. Diesel Fuel
(if equipped with DPF)
We recommend you to use only
the regulated diesel fuels, when
your vehicle is equipped with
the DPF system.
When you use other diesel fuels,
which is high in sulfurs (above
50 ppm) or contains unspecified
additives, it may damage the
DPF system and cause the white
smoke emission.CAUTION
