Make sure to install new spark plugs of
the correct heat range.
When assembling parts, be sure to
wipe out foreign substances inside
and outside of the boot bottom of the
ignition coil and the insulator of the
spark plug with a soft cloth to prevent
contamination of the spark plug
insulator.
Cooling system
Check cooling system components, such
as radiator, coolant reservoir, hoses and
connections for leakage and damage.
Replace any damaged parts.
Engine coolant
The coolant should be changed at the
intervals specified in the maintenance
schedule.
Engine coolant/water-cooled
intercooler coolant
The coolant should be changed at the
intervals specified in the maintenance
schedule.
Automatic transmission fluid
Automatic transmission fluid should
not be checked under normal usage
conditions.
Have the automatic transmission fluid
be changed by an authorized HYUNDAI
dealer according to the maintenance
schedule.
Information
Automatic transmission fluid color is red
when new.
As the vehicle is driven, the automatic
transmission fluid will begin to look
darker.
This is a normal condition. It does not
need to be replaced based on the color
change.
NOTICE
The use of a non-specified fluid could
result in transmission malfunction and
failure.
Use only specified automatic
transmission fluid. (Refer to
“Recommended Lubricants and
Capacities” section in chapter 2.)
Dual clutch transmission fluid (if
equipped)
Inspect the dual clutch transmission fluid
according to 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.
Parking brake
Inspect the parking brake system
including the parking brake lever and
cables.

Maintenance9-16
ENGINE OIL
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.
For more information on checking the
pads or lining wear limit, refer to the
HYUNDAI web site.
(http://service.hyundai-motor.com)
Propeller shaft
Check the propeller shaft, boots, clamps,
rubber couplings and center-bearing
rubber for cracks, deterioration, or
damage. Replace any damaged parts
and if necessary, repack the grease.
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 engine
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 engine oil level
Engine oil is used for lubricating,
cooling, and operating various hydraulic
components in the engine. Engine oil
consumption while driving is normal,
and it is necessary to check and refill the
engine oil regularly. Also, check and refill
the oil level within the recommended
maintenance schedule to prevent
deterioration of oil performance.
Check the engine oil following the below
procedure.
Gasoline engine
1. Follow all of the oil manufacturer’s precautions.
2. Be sure the vehicle is on the level ground in P (Park) with the parking
brake set and the wheels blocked.
3. Turn the engine on and warm the engine up until the coolant
temperature reaches a constant
normal temperature.
4. Turn the engine off, remove the oil filler cap and pull the dipstick out.
Wait for 15 minutes for the oil to return
to the oil pan.
5. Wipe the dipstick clean and re-insert it fully.

Maintenance9-22
Checking the brake fluid level
OTMA090005
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 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
be 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 be 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 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” section in chapter 2).

dusty or sandy areas, replace the element
more often than the usual recommended
intervals (refer to “Maintenance Under
Severe Usage Conditions” in this chapter).
NOTICE

[Do not drive with the air cleaner filter
removed. This will result in excessive
engine wear.

[ When removing the air cleaner filter,
be careful that dust or dirt does not
enter the air intake, or damage may
result.

[ Use HYUNDAI genuine parts or the
equivalent specified for your vehicle.
Use of non-genuine parts could
damage the air flow sensor.

Wheel alignment and tire
balance
The wheels on your vehicle were
aligned and balanced carefully at the
factory to give you the longest tire
life and best overall performance.
In most cases, you will not need to
have your wheels aligned again.
However, if you notice unusual tire
wear or your vehicle pulling one way
or the other, the alignment may need
to be reset.
If you notice your vehicle vibrating
when driving on a smooth road, your
wheels may need to be rebalanced.
NOTICE
Incorrect wheel weights can
damage your vehicle’s aluminum
wheels. Use only approved wheel
weights.
Tire replacement
Tread wear indicatorTread wear indicator
OHI078080
If the tire is worn evenly, a tread
wear indicator will appear as a solid
band across the tread. This shows
there is less than 1/16 inch (1.6mm) of
tread left on the tire. Replace the tire
when this happens.
Do not wait for the band to appear
across the entire tread before
replacing the tire.
WARNING
To reduce the risk of DEATH or
SERIOUS INJURY:

[ Replace tires that are worn, show
uneven wear, or are damaged.
Worn tires can cause loss of
braking effectiveness, steering
control, and traction.

[ Always replace tires with the
same size as each tire that was
originally supplied with this
vehicle. Using tires and wheels
other than the recommended
sizes could cause unusual
handling characteristics, poor
vehicle control, or negatively
affect your vehicle’s Anti-Lock
Brake System (ABS) resulting in a
serious accident.

[ When replacing tires (or wheels),
it is recommended to replace
the two front or two rear tires (or
wheels) as a pair. Replacing just
one tire can seriously affect your
vehicle’s handling.

[ Tires degrade over time, even
when they are not being used.
Regardless of the remaining
tread, HYUNDAI recommends
that tires be replaced after six (6)
years of normal service.

[ Heat caused by hot climates or
frequent high loading conditions
can accelerate the aging process.
Failure to follow this warning
may cause sudden tire failure,
which could lead to a loss of
vehicle control resulting in an
accident.

WARNING
The temperature grade for this
tire is established for a tire that
is properly inflated and not
overloaded. Excessive speed,
under-inflation, over-inflation, or
excessive loading, either separately
or in combination, can cause heat
build-up and possible sudden
tire failure. This may cause loss
of vehicle control resulting in an
accident.
Tire Terminology and Definitions
Air Pressure
The amount of air inside the tire pressing
outward on the tire. Air pressure is
expressed in pounds per square inch
(psi) or kilopascal (kPa).
Accessory Weight
This means the combined weight of
optional accessories. Some examples
of optional accessories are automatic
transmission, power seats, and air
conditioning.
Aspect Ratio
The relationship of a tire’s height to its
width.
Belt
A rubber coated layer of cords that is
located between the plies and the tread.
Cords may be made from steel or other
reinforcing materials.
Bead
The tire bead contains steel wires
wrapped by steel cords that hold the tire
onto the rim.
Bias Ply Tire
A pneumatic tire in which the plies are
laid at alternate angles less than 90
degrees to the centerline of the tread.
Cold Tire Pressure
The amount of air pressure in a tire,
measured in pounds per square inch (psi)
or kilopascals (kPa) before a tire has built
up heat from driving.
Curb Weight
This means the weight of a motor vehicle
with standard and optional equipment
including the maximum capacity of fuel,
oil and coolant, but without passengers
and cargo.

Maintenance9-44
All Season Tires
HYUNDAI specifies all season tires
on some models to provide good
performance for use all year round,
including snowy and icy road conditions.
All season tires are identified by ALL
SEASON and/or M+S (Mud and Snow) on
the tire sidewall. Snow tires have better
snow traction than all season tires and
may be more appropriate in some areas.
Snow Tires
If you equip your car with snow tires,
they should be the same size and have
the same load capacity as the original
tires. Snow tires should be installed on
all four wheels; otherwise, poor handling
may result. Snow tires should carry 4
psi (28 kPa) more air pressure than the
pressure recommended for the standard
tires on the tire label on the driver’s
side of the center pillar, or up to the
maximum pressure shown on the tire
sidewall, whichever is less. Do not drive
faster than 75 mph (120 km/h) when your
vehicle is equipped with snow tires.
Radial-Ply Tires
Radial-ply tires provide improved tread
life, road hazard resistance and smoother
high speed ride. The radial-ply tires used
on this vehicle are of belted construction,
and are selected to complement the
ride and handling characteristics of your
vehicle.
Radial-ply tires have the same load
carrying capacity, as bias-ply or bias
belted tires of the same size, and use the
same recommended inflation pressure.
Mixing of radial-ply tires with bias-ply or
bias belted tires is not recommended.
Any combinations of radial-ply and bias-
ply or bias belted tires when used on the
same vehicle will seriously deteriorate
vehicle handling. The best rule to follow
is: Identical pairs of radial-ply tires
should always be used as a set for the
front tires and a set for the rear tires.
Longer wearing tires can be more
susceptible to irregular tread wear. It is
very important to follow the tire rotation
interval in this chapter to achieve the
tread life potential of these tires. Cuts
and punctures in radial-ply tires are
repairable only in the tread area, because
of sidewall flexing. Consult your tire
dealer for radial-ply tire repairs.
WARNING
Do not mix bias ply and radial ply tires
under any circumstances. This may
cause unusual handling characteristics
that may cause loss of vehicle control
resulting in an accident.
