Owner maintenance schedule
When you stop for fuel:
• Check the engine oil level.
• Check coolant level in the engine
coolant reservoir.
• Check the windscreen washer fluid
level.
• Check for low or under-inflated
tyres.
Whilst operating your vehicle:
• Note any changes in the sound of
the exhaust or any smell of exhaust
fumes in the vehicle.
• Check for vibrations in the steering
wheel. Notice if there is any
increased steering effort or loose-
ness in the steering wheel, or
change in its straight-ahead position.
• Notice if your vehicle constantly
turns slightly or “pulls” to one side
when travelling on smooth, level
road.
• When stopping, listen and check for
unusual sounds, pulling to one side,
increased brake pedal travel or
“hard-to-push” brake pedal.
• If any slipping or changes in the
operation of your transaxle occurs,
check the transaxle fluid level.
• Check the automatic transaxle
P (Park) function.
• Check the parking brake.
• Check for fluid leaks under your vehi-
cle (water dripping from the air con-
ditioning system during or after use
is normal).
At least monthly:
• Check coolant level in the engine
coolant reservoir.
• Check the operation of all exterior
lights, including the stoplights, turn
signals and hazard warning flashers.
• Check the inflation pressures of all
tyres including the spare for tyres
that are worn, show uneven wear,
or are damaged.
• Check for loose wheel nuts.
Be careful when checking your
engine coolant level when the
engine is hot. This may result in
coolant being blown out of the
opening and cause serious
burns and other injuries.

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 authorised HYUNDAI
dealer.Information
Three kinds of fuses are used:
blade type for lower amperage rat-
ing, cartridge type and multi fuse
for higher amperage ratings.

Maintenance
Inner panel fuse replacement
1. Turn the engine 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 authorised HYUNDAI
dealer.
Information
If you do not have a spare, use a
fuse of the same rating from a cir-
cuit you may not need for operat-
ing the vehicle, such as the ciga-
rette lighter fuse.
If the headlamps or other electrical
components do not work and the
fuses are OK, check the fuse block in
the engine compartment. If a fuse is
blown, it must be replaced with the
same rating.

LIGHT BULBS
Use only bulbs of the specified
wattage.
All bulbs are available from your
HYUNDAI dealers Parts Department.
After heavy driving, rain or wash-
ing, headlamp and tail lamp lens-
es could appear frosty. This condi-
tion is caused by the temperature
difference between the lamp
inside and outside. This is similar
to the condensation on your win-
dows inside your vehicle during
the rain and doesn’t indicate a
problem with your vehicle. If the
water leaks into the lamp bulb cir-
cuitry, we recommend that the
system be checked by an autho-
rised HYUNDAI dealer.
NOTICE
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 the necessary
tools, the correct bulbs and the
expertise, consult an autho-
rised 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
headlamp assembly to get to
the bulb(s).
Removing/installing the head-
lamp assembly can result in
damage to the vehicle.
CAUTION
Working on the lights
Prior to working on the light, firm-
ly apply the parking brake,
ensure that the Engine Start/Stop
button is turned to the OFF posi-
tion and turn off the lights to
avoid sudden movement of the
vehicle and burning your fingers
or receiving an electric shock.
WARNING
The headlight aiming adjust-
ment may be necessary after
the headlight assembly is rein-
stalled. If you are unsure how to
replace or aim the headlight, we
recommend that you consult
with an authorised HYUNDAI
dealer.
