BRAKE AND CLUTCH (IF EQUIPPED) FLUID
Checking the brake/clutch
fluid level
Check the fluid level in the reservoir
periodically. 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 nor-
mal condition associated 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 lubri-
cants or capacities” in section 8.)
Never mix different types of fluid.
WARNING - Brake fluid
When changing and adding
brake/clutch fluid, handle it
carefully. Do not let it come in
contact with your eyes. If
brake/clutch fluid should come
in contact with your eyes, imme-
diately flush them with a large
quantity of fresh tap water. Have
your eyes examined by a doctor
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, as paint damage will
result. Brake/clutch fluid, which
has been exposed to open air
for an extended time should
never be used as its quality can-
not 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
Checking the power steering
fluid level
With the vehicle on level ground,
check the fluid level in the power
steering reservoir periodically. The
fluid should be between MAX and
MIN marks on the side of the gauge
at the normal temperature.
Before adding power steering fluid,
thoroughly clean the area around the
reservoir cap to prevent power steer-
ing fluid contamination.
If the level is low, add fluid to the
MAX level.
✽ ✽
NOTICE
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 sys-
tem 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 lubri-
cants or capacities" in section 8.)
Checking the power steering
hose
Check the connections for oil leaks,
damage 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 peri-
ods with a low power steering
fluid level.
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/or noise from the power
steering system.
(Continued)
(Continued)
The use of the non-specified
fluid could reduce the effective-
ness of the power steering sys-
tem and cause damage to it.

FUSES
A vehicle’s electrical system is pro-
tected from electrical overload dam-
age by fuses.This vehicle has 3 fuse panels, one
located in the driver’s side panel bol-
ster, the others in the engine com-
partment.
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.
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 authorized
HYUNDAI dealer.
Three kinds of fuses are used: blade
type for lower amperage rating, car-
tridge type, and fusible link for higher
amperage ratings.

Normal Blown
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 alu-
minum foil instead of the prop-
er 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 circuit and damage the
system.

Maintenance
Waxing
A good coat of wax is a barrier
between your paint and contaminate.
Keeping a good coat of wax on your
vehicle will help protect it.
Wax the vehicle when water will no
longer bead on the paint.
Always wash and dry the vehicle
before waxing. Use a good quality
liquid or paste wax, and follow the
manufacturer’s instructions. Wax all
metal trim to protect it and to main-
tain its luster.
Removing oil, tar, and similar materi-
als with a spot remover will usually
strip the wax from the finish. Be sure to
re-wax these areas even if the rest of
the vehicle does not yet need waxing.CAUTION
Wiping dust or dirt off the
body with a dry cloth will
scratch the finish.
Do not use steel wool, abra-
sive cleaners, or strong deter-
gents containing highly alka-
line or caustic agents on
chrome-plated or anodized
aluminum parts. This may
result in damage to the protec-
tive coating and cause discol-
oration or paint deterioration.
CAUTION
Water washing in the engine
compartment including high
pressure water washing may
cause the failure of electrical
circuits or engine and related
part located in the engine
compartment.
Never allow water or other liq-
uids to come in contact with
electrical/electronic compo-
nents inside the vehicle as
this may damage them.

RECOMMENDED LUBRICANTS AND CAPACITIES
These lubricants and fluids are recommended for use in your vehicle.
*1Refer to the recommended SAE viscosity numbers on the next page.
*2Engine oils labeled Energy Conserving Oil are now available. Along with other additional benefits, they contribute to fuel economy by reducing
the amount of fuel necessary to overcome engine friction. Often, these improvements are difficult to measure in everyday driving, but in a year’s
time, they can offer significant cost and energy savings.
*
3If the API service SM engine oil is not available in your country, you are able to use API service SL, ILSAC GF-4, ACEA 3.
To help achieve proper engine and powertrain performance and durability, use only lubricants of the proper quality.
The correct lubricants also help promote engine efficiency that results in improved fuel economy.

Recommended SAE viscosity
number Engine oil viscosity (thickness) has an
effect on fuel economy and cold
weather operating (engine start and
engine oil flowability). Lower viscosity
engine oils can provide better fuel
economy and cold weather perform-
ance, however, higher viscosity engine
oils are required for satisfactory lubri-
cation in hot weather. Using oils of any
viscosity other than those recommend-
ed could result in engine damage.When choosing an oil, consider the
range of temperature your vehicle will
be operated in before the next oil
change. Proceed to select the recom-
mended oil viscosity from the chart.
CAUTION
Always be sure to clean the area
around any filler plug, drain
plug, or dipstick before check-
ing or draining any lubricant.
This is especially important in
dusty or sandy areas and when
the vehicle is used on unpaved
roads. Cleaning the plug and
dipstick areas will prevent dirt
and grit from entering the
engine and other mechanisms
that could be damaged.
