Maintenance

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 headlamp 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 (12V) and terminals.

[Check the brake fluid level.

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 maintenance
schedule.
Reduction Gear Fluid
The reduction gear fluid should be
inspected 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 disc, and the rotor
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
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 damage.

Checking the Brake Fluid Level
ONE1091004
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. The level will fall
with accumulated kilometers. 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.
WARNING
If the brake system requires frequent
additions of fluid this could indicate
a leak in the brake system. Have the
vehicle inspected by an authorized
HYUNDAI dealer.
WARNING
Do not let brake fluid enter into your
eyes. If brake fluid gets in your eyes,
flush your eyes with clean water for
at least 15 minutes and get immediate
medical attention.
NOTICE

[Do not allow brake fluid to contact
the vehicle’s body paint, as it will
result in paint damage.

[NEVER use brake fluid which has
been exposed to open air for an
extended time, as its quality cannot
be guaranteed. It should be disposed
of properly.

[Do not use the wrong type of brake
fluid. A few drops of mineral based
oil in your brake system can damage
brake system parts.
Information
Use only the specified brake fluid (refer
to “Recommended Lubricants and
Capacities” section in chapter 2).

Maintenance
9-14
Checking the Washer Fluid Level
ONE1091005
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.
WASHER FLUID REDUCTION GEAR FLUID
There is no reduction gear fluid level
gauge in the vehicle. Check the
reduction gear fluid every 60,000 km
regularly. If the vehicle is driven under
severe condition, check the maintenance
under severe usage condition and
consult an authorized HYUNDAI dealer.
