lead to vehicle damage, an accident, or
personal injury. This chapter provides
instructions only for the maintenance
items that are easy to perform.
Your vehicle should not be modified in
any way. Such modifications may
adversely affect the performance, safety or durability of your vehicle and may, in

Owner Maintenance
WARNING Performing maintenance work on a
vehicle can be dangerous. If you lack
sufficient knowledge and experience or
the proper tools and equipment to do the
work, we recommend that it is done by an
authorized HYUNDAI dealer. ALWAYS
follow these precautions for performing
maintenance work:
• Park your vehicle on level ground. Shift the vehicle to P (Park), apply the
parking brake, and press the Start/Stop
button to the OFF position.
• Block the tires (front and back) to prevent the vehicle from moving.
Remove loose clothing or jewelry that
can become entangled in moving parts.
• Keep flames, sparks, or smoking materials away from the battery and
motor related parts.
WARNING Make sure to turn the Start/Stop button to
the OFF position to shut down the vehicle
before performing maintenance work on
the vehicle.
The following lists are vehicle checks and
inspections that should be performed by
the owner or an authorized HYUNDAI
dealer 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 vehicle
checks are generally not covered by
warranties and you may be charged for
labor, parts and lubricants used. The electric control system in the vehicle
may cause malfunction or other negative
impact on the artificial heart and the
artificial internal organs. Be sure to
inquire the impact of the electric control
system on the artificial organs from the
medical product corporation.
Owner Maintenance Schedule
When you stop for charging:
• Check the coolant level in the coolant
reservoir.
• Check the windshield washer fluid level.
• Check for low or under-inflated tires.
WARNING Be careful when checking your coolant
level if the motor compartment is hot.
This may result in coolant being blown
out of the opening and cause serious
burns and other injuries.
While operating your vehicle:
• Check for vibrations in the steering wheel. Notice if there is any increased
steering effort or looseness in the
steering wheel, or change in its
straight-ahead position.
• Notice if your vehicle constantly turns slightly or “pulls” to one side when
traveling 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 operation of your gear shift occurs,
check the shift gear fluid level.
• Check the shift gear P (Park) function.
• Check the parking brake.

• Check for fluid leaks under your vehicle (water dripping from the air
conditioning system during or after use
is normal).
At least monthly:
• Check coolant level in the coolant reservoir.
• Check the operation of all exterior lights, including the stoplights, turn
signals and hazard warning flashers.
• Check the inflation pressures of all tires including the spare for tires that are
worn, show uneven wear, or are
damaged.
• Check for loose wheel lug nuts.
At least twice a year: (for example,
every Spring and Autumn)
• Check radiator, heater and air conditioning hoses for leaks or
damage.
• Check windshield washer spray and wiper operation. Clean wiper blades
with a clean cloth dampened with
washer fluid.
• Check headlight alignment.
• Check the seat belts for wear and function.
At least once a year:
• Clean body and door drain holes.
• Lubricate door hinges and hood hinges.
• Lubricate door and hood locks and latches.
• Lubricate door rubber weather strips.
• Check the air conditioning system.
• Inspect and lubricate shift gear linkage and controls.
• Clean the battery (12 V) and terminals.
• Check the brake fluid level.

Coolant
The coolant should be changed at the
intervals specified in the maintenance
schedule.
Gear Fluid
The gear fluid should be inspected and
replaced according to the intervals
specified in the maintenance schedule.
Brake Hoses and Lines
Visually check for proper installation,
chafing, cracks, deterioration and any
leakage. Replace any deteriorated or
damaged parts immediately.
Brake Fluid
Check the 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 conforming to DOT 4
specification.
Brake Discs, Pads, Calipers
and Rotors
Check the pads, the discs, and the rotors
for any excessive wear-out. Inspect
calipers for any 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

Coolant
B9001901
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 or F and the MIN or L marks on
the side of the coolant reservoir when the
parts in the motor compartment is cool.
If the coolant level is low, have the vehicle
inspected by an authorized HYUNDAI
dealer.
WARNING
Keep hands, clothing, and tools away
from the rotating fan blades of the
cooling fan. The cooling fan may continue
to operate even though the vehicle is
turned off and can cause serious injury.
The electric motor for the cooling fan is
controlled by vehicle coolant
temperature, refrigerant pressure and
vehicle speed. As the vehicle coolant
temperature decreases, the electric
motor will automatically shut off.
Recommended coolant
• When adding coolant, use only deionized water, distilled water, or soft
water for your vehicle and never mix
hard water in the coolant filled at the
factory.
• An incorrect coolant mixture may result in severe malfunction or motor
damage.
• Do not use alcohol or methanol coolant or mix them with the specified coolant.
• Do not use a solution that contains more than 60% antifreeze or less than
35% antifreeze, which could reduce the
effectiveness of the solution.
For mixing percentage, refer to the
following table:
Information If in doubt about the mix ratio, a 50 % water
and 50 % antifreeze mix is the easiest to mix
together because it is the same quantity for
each.

Brake Fluid
Checking the Brake Fluid
Level
B9002301
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 thoroughly to prevent
brake fluid contamination.
If the level is low, add the specified brake
fluid to the MAX level. If the fluid level is
excessively low or frequent additions are
required have the brake system inspected
by an authorized HYUNDAI dealer.
WARNING If brake fluid comes in contact with your
eyes, flush your eyes with clean water for
at least 15 minutes and get immediate
medical attention.

Washer Fluid
Checking the Washer Fluid
Level
B9002701
Check the fluid level in the washer fluid
reservoir and add fluid if necessary. Plain
water may be used if washer fluid is not
available. However, use washer solvent
with antifreeze characteristics in cold
climates to prevent freezing.
WARNING To prevent serious injury or death, take
the following safety precautions when
using washer fluid:
• 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. Washer fluid is
harmful to humans and animals.
• Keep washer fluid away from children and animals.
Cabin Air Filter
Filter Inspection
The cabin air filter must 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 frequently and replaced sooner.
Replace the cabin air filter by following
the procedure below and be careful to
avoid damaging other components.
Filter Replacement
1. Open the hood.
2. Lift up the front trunk cover while depressing the front trunk lever (1).
