Cooling System
Check cooling system components,
such as radiator, coolant reservoir,
hoses and connections for leakage
and damage. Replace any damaged
parts.
Coolant
The coolant should be changed at
the intervals specified in the mainte-
nance schedule.
Reduction Gear Fluid
Inspect the reduction gear fluid according to the maintenance sched-
ule.
Brake Hoses and Lines
Visually check for proper installation,
chafing, cracks, deterioration and
any leakage. Replace any deteriorat-
ed or damaged parts immediately.
Brake Fluid
Check brake fluid level in the brake
fluid reservoir. The level should be
between the MIN and the MAX
marks on the side of the reservoir.
Use only hydraulic brake fluid con-
forming to DOT 4 specification.
Brake Discs, Pads, Calipers
and Rotors
Check the pads for excessive wear,
discs for run out and wear, and
calipers for fluid leakage.
Suspension Mounting Bolts
Check the suspension connections
for looseness or damage. Retighten
to the specified torque.
Steering Gear Box, Linkage &
Boots/Lower Arm Ball Joint
With the vehicle stopped and the
vehicle off, check for excessive free-
play in the steering wheel. Check the
linkage for bends or damage. Check
the dust boots and ball joints for
deterioration, cracks, or damage.
Replace any damaged parts.
Drive Shafts and Boots
Check the drive shafts, boots and
clamps for cracks, deterioration, or
damage. Replace any damaged
parts and, if necessary, repack the
grease.
Air Conditioning Refrigerant
Check the air conditioning lines and
connections for leakage and dam-
age.

MaintenanceC
C OO OO LLAA NN TT
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 the MAX and the MIN
marks on the side of the coolant
reservoir when the parts in the motor
compartment is cool.
If the coolant level is low, have your
vehicle inspected by an authorized
HYUNDAI dealer. Use only designat-
ed coolant water for electric vehicles,
adding other types of water or
antifreeze can damage the vehicle. The electric motor for the cooling fan
is controlled by coolant temperature,
refrigerant pressure and vehicle
speed. As the coolant temperature
decreases, the electric motor will
automatically shut off. This is a nor-mal condition.
OAEE076002L
Since a specific coolant water is
applied for electric vehicles,replenishment of other
antifreeze or water may cause
problems to the vehicle.
WARNING
The electric motor for the cool-
ing fan may continue to operate
or start up when the vehicle isnot running and can cause seri-
ous injury. Keep hands, clothing
and tools away from the rotat-
ing fan blades of the coolingfan.

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 the specified
brake 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, have
the brake system checked by an
authorized HYUNDAI dealer.
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 beused as its quality cannot be
guaranteed. It should be dis-
posed of properly.
Do not use the wrong kind of brake fluid. A few drops of min-
eral based oil, such as engine
oil, in your brake system can
damage brake system parts.
Information
Use only the specified brake fluid
(refer to "Recommended Lubricants
and Capacities" in chapter 8).
i
NOTICE
If the brake system requires fre-
quent additions of fluid thiscould indicate a leak in the
brake system. Have the vehicle
inspected by an authorized
HYUNDAI dealer.
WARNING
Do not allow brake fluid to come
in contact with your eyes. Ifbrake fluid comes in contact
with your eyes, flush your eyes
with clean water for at least 15
minutes and get immediatemedical attention.

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 wash-
er fluid is not available. However, use
washer solvent with antifreeze char-
acteristics in cold climates to preventfreezing.
OAEE076004 To prevent serious injury or
death, take the following safetyprecautions when using washerfluid:
Do not use coolant or
antifreeze in the washer fluid
reservoir.
Coolant can severely obscure
visibility when sprayed on the
windshield and may cause loss
of vehicle control resulting in
an accident or damage to paint
and body trim.
Do not allow sparks or flame to contact the washer fluid or the
washer fluid reservoir. Washer
fluid may contain alcohol and
can be flammable.
Do not drink washer fluid and
avoid contact with skin. Washerfluid is harmful to humans andanimals.
Keep washer fluid away from
children and animals.

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 should be inspected more fre-
quently and replaced sooner.Replace the climate control air filter
by following the procedure below and
be careful to avoid damaging other
components.
1. With the glove box open, removethe stoppers on both sides to allow
the glove box to hang freely on the
hinges. 2. Remove the support rod (1).
