Features of your vehicle
Checking the amount of air
conditioner refrigerant and
compressor lubricant
When the amount of refrigerant is
low, the performance of the air condi-
tioning is reduced. Overfilling also
has a bad influence on the air condi-
tioning system.
Therefore, if abnormal operation is
found, we recommend that the sys-
tem be inspected by an authorized
HYUNDAI dealer.
WARNING - Vehicles
equipped with R-134a
Because the refriger-
ant is at very high
pressure, the air con-
ditioning system
should only be serv-
iced by trained and certified
technicians. It is important that
the correct type and amount of
oil and refrigerant is used.
Otherwise, it may cause damage
to the vehicle and personal injury.

Maintenance
OWNER MAINTENANCE
The following lists are vehicle checks
and inspections that should be per-
formed at the frequencies indicated
to help ensure safe, dependable
operation of your vehicle.
Any adverse conditions should be
brought to the attention of your deal-
er as soon as possible.
These Owner Maintenance Checks
are generally not covered by war-
ranties and you may be charged for
labor, parts and lubricants used.Owner maintenance schedule
When you stop for fuel:
• Check the engine oil level.
• Check coolant level in coolant
reservoir.
• Check the windshield washer fluid
level.
• Look for low or under-inflated tires.
While operating your vehicle:
• Note any changes in the sound of
the exhaust or any smell of
exhaust fumes in the vehicle.
• Check for vibrations in the steering
wheel. Notice any increased steer-
ing effort or looseness in the steer-
ing 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 transmission
occurs, check the transmission
fluid level.
• Check automatic transmission P
(Park) function.
• Check parking brake.
• Check for fluid leaks under your
vehicle (water dripping from the air
conditioning system during or after
use is normal).
WARNING
Be careful when checking your
engine coolant level when the
engine is hot. Scalding hot
coolant and steam may blow
out under pressure. This could
cause burns or other serious
injury.

ENGINE OIL
Checking the engine oil level
1.Be sure the vehicle is on level
ground.
2.Start the engine and allow it to
reach normal operating tempera-
ture.3.Turn the engine off and wait for a
few minutes (about 5 minutes) for
the oil to return to the oil pan.
4.Pull the dipstick out, wipe it clean,
and re-insert it fully.
5.Pull the dipstick out again and
check the level. The level should be
between F and L.

BRAKE FLUID
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 nor-
mal condition associated with the
wear of the brake linings.If the fluid level is excessively low, we
recommend that the system be
checked by an authorized HYUNDAI
dealer.
Use only the specified brake fluid.
(Refer to “Recommended lubricants
or capacities” in section 8.)
Never mix different types of fluid.
✽NOTICE
Before removing the brake filler
cap, read the warning on the cap.
WARNING - Brake fluid
When changing and adding
brake fluid, handle it carefully.
Do not let it come in contact
with your eyes. If brake fluid
should 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 - Loss of
brake fluid
In the event the brake system
requires frequent additions of
fluid, we recommend that the
system be inspected by an
authorized HYUNDAI dealer.
CAUTION
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.
OBH071006
WARNING
Clean filler cap before remov-
ing. Use only DOT3 or DOT4
brake fluid from a sealed con-
tainer.

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
The reservoir is translucent so that
you can check the level with a quick
visual inspection.
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 characteristics in cold cli-
mates to prevent freezing.
WARNING- Coolant
• 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 amounts
of alcohol and can be flamma-
ble under certain circum-
stances. Do not allow sparks
or flame to contact the washer
fluid 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.
