BRAKE AND CLUTCH (IF EQUIPPED) FLUID
G080100AUN
Checking the brake/clutch fluid
level
Check the fluid level in the reservoir peri-
odically. The fluid level should be
between MAX and MIN marks on the
side of the reservoir.
Before removing the reservoir cap and
adding brake/clutch fluid, clean the area
around the reservoir cap thoroughly to
prevent brake/clutch fluid contamination. If the level is low, add fluid to the MAX
level. The level will fall with accumulated
mileage. This is a normal condition asso-
ciated with the wear of the brake linings.
If the fluid level is excessively low, have
the brake system checked by an author-
ized HYUNDAI dealer.
Use only the specified brake/clutch fluid.
(Refer to “Recommended lubricants orcapacities” in section 8.)
Never mix different types of fluid.
WARNING - Brake fluid
When changing and adding
brake/clutch fluid, handle it careful-
ly. Do not let it come in contact with
your eyes. If brake/clutch fluid
should come in contact with your
eyes, immediately flush them with a
large quantity of fresh tap water.
Have your eyes examined by a doc-
tor as soon as possible.
WARNING - Loss of brake fluid
In the event the brake system
requires frequent additions of fluid,
the vehicle should be inspected by
an authorized HYUNDAI dealer.
OBK079007
CAUTION
Do not allow brake/clutch fluid to contact the vehicle's body paint, aspaint damage will result.Brake/clutch fluid, which has been exposed to open air for an extended
time should never be used as itsquality cannot be guaranteed. It should be disposed of properly.Don't put in the wrong kind of fluid.
A few drops of mineral-based oil,such as engine oil, in your brake / clutch system can damage brake /clutch system parts.

POWER STEERING FLUID
G090100ABH
Checking the power steering fluid
level
With the vehicle on level ground, check
the fluid level in the power steering reser-
voir periodically. The fluid should be
between MAX and MIN marks on the
side of the gauge at the normal tempera-
ture. Before adding power steering fluid, thor-oughly clean the area around the reser-
voir cap to prevent power steering fluidcontamination.
If the level is low, add fluid to the MAX
level.
✽✽
NOTICE - (if equipped)
Check that the fluid level is in the
"HOT" range on the gauge. If the fluid
is cold, check that it is in the "COLD"
range.
In the event the power steering system requires frequent addition of fluid, the
vehicle should be inspected by an
authorized HYUNDAI dealer.
Use only the specified power steering fluid. (Refer to "Recommended lubricants
or capacities" in section 8.)
G090200AEN
Checking the power steering hose
Check the connections for oil leaks, dam-
age and twists in the power steering
hose before driving.
CAUTION
To avoid damage to the power steering pump, do not operate the
vehicle for prolonged periods with a low power steering fluidlevel.
Never start the engine when the reservoir tank is empty.
When adding fluid, be careful that dirt does not get into the tank.
Too little fluid can result in increased steering effort and/ornoise from the power steering
system.
The use of the non-specified fluid could reduce the effectiveness ofthe power steering system andcause damage to it.

G170100AEN Filter inspection The climate control air filter should be replaced according to the Maintenance
Schedule. If the vehicle is operated in
severely air-polluted cities or on dusty
rough roads for a long period, it shouldbe inspected more frequently and
replaced earlier. When you replace the
climate control air filter, replace it per-
forming the following procedure, and be
careful to avoid damaging other compo-
nents. G170200ABK Filter replacement
1. Open the glove box and remove the
support rod (1).CAUTION
Do not drive with the air cleaner
removed; this will result in exces-
sive engine wear.
When removing the air cleaner fil- ter, be careful that dust or dirtdoes not enter the air intake, or
damage may result.
Use a HYUNDAI genuine part. Use of non-genuine parts could dam-age the air flow sensor.

Battery recharging
Your vehicle has a maintenance-free,
calcium-based battery.
If the battery becomes discharged in a
short time (because, for example, the
headlights or interior lights were left on
while 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 while 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
When you don’t use the vehicle
for a long time in the low temper-ature area, separate the batteryand keep it indoors.
Always charge the battery fully to prevent the battery case dam-
aged in low temperature area.

FUSES
G210000ABK
A vehicle’s electrical system is protected
from electrical overload damage by
fuses. This vehicle has 3 fuse panels, one locat-
ed in the driver’s side panel bolster, the
others in the engine compartment.
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 authorized HYUNDAI dealer.
Three kinds of fuses are used: blade type
for lower amperage rating, cartridge type,
and fusible link 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 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 because it may cause a short circuitand damage the system.

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.
