Maintenance
Battery recharging
Your vehicle has a maintenance-free,
calcium-based battery.
• If the battery becomes discharged
in a short time (because, for exam-
ple, the headlights or interior lights
were left on whilst the vehicle was
not in use), recharge it by slow
charging (trickle) for 10 hours.
• If the battery gradually discharges
because of high electric load whilst
the vehicle is being used, recharge
it at 20-30A for two hours.WARNING- Recharging
battery
When recharging the battery,
observe the following precau-
tions:
• The battery must be removed
from the vehicle and placed in
an area with good ventilation.
• Do not allow cigarettes,
sparks, or flames near the bat-
tery.
• Watch the battery during
charging, and stop or reduce
the charging rate if the battery
cells begin gassing (boiling)
violently or if the temperature
of the electrolyte of any cell
exceeds 49°C.
• Wear eye protection when
checking the battery during
charging.
(Continued)(Continued)
• Disconnect the battery charg-
er in the following order.
1. Turn off the battery charger
main switch.
2. Unhook the negative clamp
from the negative battery ter-
minal.
3. Unhook the positive clamp
from the positive battery ter-
minal.

FUSES
A vehicle’s electrical system is pro-
tected from electrical overload dam-
age by fuses.
This vehicle has 2 fuse panels, one
located in the driver’s side panel bol-
ster, the other in the engine compart-
ment 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 have 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 authorised
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 replace-
ment
• 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 alumini-
um foil instead of the proper
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 as it may cause a short
circuit and damage the system.

3. 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.
4. 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
authorised HYUNDAI dealer.Main fuse
If the main fuse is blown, it must be
removed as follows:
1. Disconnect the negative battery
cable.
2. Remove the nuts shown in the pic-
ture above.
3. Replace the fuse with a new one
of the same rating.
4. Reinstall in the reverse order of
removal.
✽NOTICE
If the electrical system is not operat-
ing, the main fuse may be blown,
even though the engine compart-
ment panel fuse and inner fuse are
not blown. The main fuse is connect-
ed to other parts and systems. We
recommend that you contact an
authorised HYUNDAI dealer.

CAUTION
After checking the fuse panel in
the engine compartment,
securely install the fuse panel
cover. If not, electrical failures
may occur from water leaking in.

Maintenance
✽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 depending on their
frequency of use. They will probably
require replacement at some point
in the life of the vehicle. Cycling the
headlights on and off more than typ-
ical use will shorten HID lamps life.
HID lamps do not fail in the same
manner as halogen incandescent
lamps. If a headlight goes out after a
period of operation, but will imme-
diately relight when the headlight
switch is cycled, it is likely the HID
lamp needs to be replaced. HID
lighting components are more com-
plex than conventional halogen
bulbs, and so have higher replace-
ment cost.
✽NOTICE
We recommend that the headlight
aiming be adjusted after an accident
or after the headlight assembly is rein-
stalled, at an authorised HYUNDAI
dealer.
1. Open the bonnet.
2. Disconnect the negative battery
cable.
3. Loosen the retaining bolts and
remove the headlight assembly
from the body of the vehicle. If you
can reach to the bulb without
removing the headlight assembly,
you don’t need do step 3.
4. Disconnect the power connec-
tor(s) from the back of the head-
light assembly.

4.With the headlight and battery in
normal condition, aim the head-
lights so the brightest portion falls
on the horizontal and vertical lines.
5.To aim the low beam left or right,
turn the driver clockwise or anti-
clockwise. To aim the low beam up
or down, turn the driver clockwise
or anticlockwise.
To aim the high beam up or down,
turn the driver clockwise or anti-
clockwise.Front fog light aiming
The front fog light can be aimed as
the same manner of the headlights
aiming.
With the front fog lights and battery
normal condition, aim the front fog
lights.

2. Evaporative emission con-
trol system
The Evaporative Emission Control
System is designed to prevent fuel
vapours from escaping into the
atmosphere.
Canister
Fuel vapours generated inside the
fuel tank are absorbed and stored in
the onboard canister. When the
engine is running, the fuel vapours
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
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
whilst maintaining good vehicle per-
formance.
Vehicle modifications
• This vehicle should not be modi-
fied. Modification of your vehicle
could affect its performance, safety
or durability and may even violate
governmental safety and emis-
sions regulations.
In addition, damage or perform-
ance problems resulting from any
modification may not be covered
under warranty.
• If you use unauthorised electronic
devices, it may cause the vehicle to
operate abnormally, wire damage,
battery discharge and fire. For your
safety, do not use unauthorised
electronic devices.
Engine exhaust petrol precau-
tions (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.
WARNING - Exhaust
Engine exhaust gases contain
carbon monoxide (CO). Though
colourless and odourless, it is
dangerous and could be lethal if
inhaled. Follow the instructions
on this page to avoid CO poi-
soning.
