Maintenance
Check the condition and connections of all cooling system hoses and
heater hoses. Replace any swollen
or deteriorated hoses.
The coolant level should be filled
between F and L marks on the side
of the coolant reservoir when theengine is cool.
If the coolant level is low, add enough
specified coolant to provide protec-tion against freezing and corrosion.
Bring the level to F, but do not over-
fill. If frequent additions are required,
we recommend that the system be
inspected by an authorized
HYUNDAI dealer.
Recommended engine coolant
When adding coolant, use onlydeionized water or soft water for
your vehicle and never mix hard
water in the coolant filled at the fac-
tory. An improper coolant mixture
can result in serious malfunction or
engine damage.
The engine in your vehicle has alu- minum engine parts and must be
protected by an ethylene-glycol-
based coolant to prevent corrosionand freezing.
DO NOT USE alcohol or methanol coolant or mix them with the spec-ified coolant.
Do not use a solution that contains more than 60% antifreeze or less
than 35% antifreeze, which would
reduce the effectiveness of thesolution.
The electric motor
(cooling fan) is con-
trolled by engine
coolant temperature,
refrigerant pressure
and vehicle speed. It may some-
times operate even when the
engine is not running. Use
extreme caution when working
near the blades of the cooling
fan so that you are not injured
by a rotating fan blades. As theengine coolant temperature
decreases, the electric motor
will automatically shut off. Thisis a normal condition.WARNING

Maintenance
Checking the brake 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 fluid, clean the
area around the reservoir cap thor-
oughly to prevent brake fluid contam-ination.
If the level is low, add fluid to the
MAX level. The level will fall with
accumulated mileage.This is a normal condition associated
with the wear of the brake linings. If
the fluid level is excessively low, werecommend that the system be
checked by an authorized HYUNDAI
dealer.
Information
Use only the specified brake fluid.
(Refer to “Recommended lubricants
or capacities” in section 8.)
Never mix different types of fluid.
Before removing the brake/clutch
filler cap, read the warning on thecap.

OEU074072 Brake fluid
When changing and adding
brake fluid, handle it carefully.Do not let it come in contact
with your eyes. If brake fluidshould come in contact with
your eyes, immediately flush
them with a large quantity of
fresh tap water. Have your eyes
examined by a doctor as soon
as possible.
WARNING
Clean filler cap before remov-
ing. Use only DOT4 brake/
clutch fluid from a sealed con-
tainer.

Maintenance
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 reser-
voir 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.Check that the fluid level is in the
"HOT" range on the reservoir. If
the fluid is cold, check that it is in
the "COLD" range.
In the event the power steering sys- tem requires frequent additions of
fluid, we recommend that the system
be inspected by an authorized
HYUNDAI dealer.
NOTICE
Do not allow brake fluid to con-
tact the vehicle's body paint, as
paint damage will result. Brake
fluid, which has been exposed
to open air for an extended time
should never be used as its
quality 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 system can damage
brake system parts.
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
reservoir.

MaintenanceUse only the specified power steer-ing fluid. (Refer to "Recommendedlubricants or capacities" in section 9.)
Checking the power steering hose
Check the connections for oil leaks,
damage and twists in the power
steering hose before driving.
Checking the washer fluid
level
Check the fluid level in the washer
fluid reservoir and add fluid if neces-
sary.
Plain water may be used if washer
fluid is not available. However, use
washer solvent with antifreeze char-
acteristics in cold climates to preventfreezing.
(Continued)
Too little fluid can result in
increased steering effort
and/or noise from the powersteering system.
The use of the non-specified
fluid could reduce the effec-
tiveness of the power steering
system and cause damage toit.

Do not use radiator coolant or
antifreeze in the washer fluid
reservoir.
Radiator coolant can severely obscure visibility when
sprayed on the windshield
and may cause loss of vehicle
control or damage to paint
and body trim.
Windshield Washer fluid
agents contain some amountsof alcohol and can be flamma-
ble under certain circum-
stances. Do not allow sparksor flame to contact the washerfluid or the washer fluid reser-
voir. Damage to the vehicle or
occupants could occur.
Windshield washer fluid is poisonous to humans and
animals. Do not drink and
avoid contacting windshield
washer fluid. Serious injury or
death could occur.

Maintenance
Checking the parking brake
Check the stroke of the parking
brake by counting the number of
“clicks’’ heard while fully applying it
from the released position. Also, the
parking brake alone should securely
hold the vehicle on a fairly steep
grade. If the stroke is more or less
than specified, we recommend that
the system be serviced by an author-
ized HYUNDAI dealer.
Stroke : 7 “clicks’’ at a force of
20 kg (44 lbs, 196 N).
Draining water from fuel filter
The fuel filter for diesel engine plays
an important role of separating water
from fuel and accumulating the waterin its bottom.
If water accumulates inthe fuel filter, the warninglight comes on when the
ignition switch is in the ONposition.
If this warning light turned
on, we recommend that
the system be serviced by
an authorized HYUNDAI
dealer.
Fuel filter cartridge replace- ment
When replacing the fuel filter car-
tridge, we recommend that you
use parts for replacement from an
authorized HYUNDAI dealer.

Auxiliary battery (VAN/Truck)
The auxiliary battery is located in
engine room. (if equipped)
Keep the battery securely mount-ed.
Keep the battery top clean and dry.
Keep the terminals and connec- tions clean, tight, and coated with
petroleum jelly or terminal grease.
Rinse any spilled electrolyte from the battery immediately with a
solution of water and baking soda. Basically equipped battery is
maintenance free type. If your
vehicle is equipped with the bat-
tery marked with LOWER and
UPPER on the side, you can check
the electrolyte level. The elec-
trolyte level should be between
LOWER and UPPER. If the elec-
trolyte level is low, it needs to add
distilled (demineralized) water
(Never add sulfuric acid or other
electrolyte). When refill, be careful
not to splash the battery and adja-
cent components. And do not
overfill the battery cells. It can
cause corrosion on other parts.After then ensure that tighten the
cell caps. We recommend that you
contact an authorized HYUNDAI
dealer.
NOTICE
Do not open the AGM battery.
WARNING

from the vehicle and placed inan area with good ventilation.
Do not allow cigarettes,
sparks, or flame near the bat-
tery.
Watch the battery during
charging, and stop or reduce
the charging rate if the batterycells begin gassing (boiling)
violently or if the temperature
of the electrolyte of any cell
exceeds 49°C (120°F).
Do not charge the AGM bat-
tery with over 14.5V. No quick-
