OWNER MAINTENANCE
The following lists are vehicle checks and
inspections that should be performed by
the owner or an authorised HYUNDAIdealer at the frequencies indicated to
help ensure safe, dependable operation
of your vehicle.
Any adverse conditions should be
brought to the attention of your dealer as
soon as possible.
These Owner Maintenance Checks are
generally not covered by warranties and
you may be charged for labour, parts and
lubricants used. Owner maintenance schedule
When you stop for fuel:
Check the engine oil level.
Check the coolant level in coolant
reservoir.
Check the windscreen washer fluid level.
Look for low or under-inflated tyres.
Check the radiator and condenser. Check if the front of the radiator and
condenser are clean and not blocked
with leaves, dirt or insects etc.
If any of the above parts are extremely
dirty or you are not sure of their condi-
tion, take your vehicle to an authorised
HYUNDAI dealer.
Whilst operating your vehicle:
Note any changes in the sound of theexhaust or any smell of exhaust fumes
in the vehicle.
Check for vibrations in the steering wheel. Notice any increased steering
effort or looseness in the steering
wheel, or change in its straight-aheadposition.
Notice if your vehicle constantly turns slightly or “pulls” to one side when trav-
elling 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 oper- ation of your transaxle occurs, check
the transaxle fluid level.
Check automatic transaxle P (Park) function.
Check the parking brake.
Check for fluid leaks under your vehicle (water dripping from the air condition-
ing system during or after use is nor-mal).
WARNING
Be careful when checking your
engine coolant level when the
engine is hot. Scalding hot coolant
and steam may blow out under
pressure. This could cause burns
or other serious injury.

At least monthly:
Check the coolant level in the engine
coolant reservoir.
Check the operation of all exterior lights, including the stoplights, turn sig-
nals and hazard warning flashers.
Check the inflation pressures of all tyres including the spare.
At least twice a year
(i.e., every Spring and Fall):
Check the radiator, heater and air con- ditioning hoses for leaks or damage.
Check the windscreen washer spray and wiper operation. Clean wiper
blades with clean cloth dampened with

Maintenance
Battery recharging
Your vehicle has a maintenance-free,
calcium-based battery.
If the battery becomes discharged in ashort time (because, for example, 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.(Continued)
When lifting a plastic-cased bat-tery, excessive pressure on the
case may cause battery acid to
leak, resulting in personal injury.
Lift with a battery carrier or with
your hands on opposite corners.
Never attempt to recharge the battery when the battery cablesare connected.
The electrical ignition system works with high voltage. Never
touch these components with theengine running or the ignition
switched on.
Failure to follow the above warn-
ings can result in serious bodily
injury or death.WARNING - Recharging
battery
When recharging the battery,
observe the following precautions:
The battery must be removed from the vehicle and placed in an area with good ventilation.
Do not allow cigarettes, sparks, or flame near the battery.
Watch the battery during charg- ing, and stop or reduce the charg-
ing rate if the battery cells begin
gassing (boiling) violently or if
the temperature of the electrolyte
of any cell exceeds 49°C (120°F).
Wear eye protection when check- ing the battery during charging.
Disconnect the battery charger in the following order.
1. Turn off the battery charger main switch.
2. Unhook the negative clamp from the negative battery terminal.
3. Unhook the positive clamp from the positive battery terminal.
CAUTION
If you connect unauthorised elec-
tronic devices to the battery, thebattery may be discharged. Never use unauthorised devices.

Maintenance
FUSESA vehicle’s electrical system is protected
from electrical overload damage by
fuses.
This vehicle has 2 fuse panels, one locat-
ed in the driver’s side panel bolster, the
other in the engine compartment 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 bemelted.
If the electrical system does not work,
first check the driver’s side fuse panel.
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 immediately
consult an authorised HYUNDAI dealer.
Three kinds of fuses are used: blade typefor lower amperage rating, cartridge type
and multi fuse for higher amperage rat-ings.
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 aluminum 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 fusesbecause it may cause a short circuit
and damage the system.

Instrument panel fuse replace- ment
1. Turn the ignition switch 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, consult an authorised
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 electrical components do not work
and the fuses are OK, check the fuse
panel in the engine compartment. If a
fuse is blown, it must be replaced.
