Maintenance
Tire care
For proper maintenance, safety, and
maximum fuel economy, you must
always maintain recommended tire
inflation pressures and stay within
the load limits and weight distribution
recommended for your vehicle.
Recommended cold tire
inflation pressures
All tire pressures (including the spare)
should be checked when the tires are
cold. “Cold Tires” means the vehicle has
not been driven for at least three hours
or driven less than 1.6 km (one mile).
Recommended pressures must be
maintained for the best ride, top vehicle
handling, and minimum tire wear.
For recommended inflation pressure,
refer to “Tire and wheels” in chapter 2.
OAI3019023OAI3019023
All specifications (sizes and pressures)
can be found on a label attached to the
driver’s side center pillar.
WARNING
Tire underinflation
Severe underinflation (70 kPa (10 psi) or
more) can lead to severe heat build-up,
causing blowouts, tread separation and
other tire failures that can result in the
loss of vehicle control leading to severe
injury or death. This risk is much higher
on hot days and when driving for long
periods at high speeds.
NOTICE
• Underinflation also results in
excessive wear, poor handling
and reduced fuel economy. Wheel
deformation also is possible. Keep
your tire pressures at the proper
levels. If a tire frequently needs
refilling, we recommend that the
system be checked by an authorized
HYUNDAI dealer.
• Overinflation produces a harsh ride,
excessive wear at the center of the
tire tread, and a greater possibility of
damage from road hazards.
NOTICE
• Warm tires normally exceed
recommended cold tire pressures
by 28 to 41 kPa (4 to 6 psi). Do not
release air from warm tires to adjust
the pressure or the tires will be
underinflated.
• Be sure to reinstall the tire inflation
valve caps. Without the valve cap,
dirt or moisture could get into the
valve core and cause air leakage. If a
valve cap is missing, install a new one
as soon as possible.

WARNING
Tire Inflation
Overinflation or underinflation can
reduce tire life, adversely affect
vehicle handling, and lead to sudden
tire failure. This could result in loss of
vehicle control and potential injury.
NOTICE
Tire pressure
Always observe the following:
• Check tire pressure when the tires
are cold. (After vehicle has been
parked for at least three hours or
hasn’t been driven more than 1.6 km
(one mile) since startup.)
• Check the pressure of your spare tire
each time you check the pressure of
other tires.
• Never overload your vehicle. Be
careful not to overload a vehicle
luggage rack if your vehicle is
equipped with one.
• Worn, old tires can cause accidents.
If your tread is badly worn, or if your
tires have been damaged, replace
them.
Checking tire inflation pressure
Check your tires once a month or more.
Also, check the tire pressure of the spare
tire.
How to check
Use a good quality gage to check
tire pressure. You can not tell if your
tires are properly inflated simply by
looking at them. Radial tires may look
properly inflated even when they’re
underinflated.
Check the tire’s inflation pressure when
the tires are cold. - “Cold” means your
vehicle has been sitting for at least three
hours or driven no more than 1.6 km (1
mile).
Remove the valve cap from the tire valve
stem. Press the tire gage firmly onto the
valve to get a pressure measurement. If
the cold tire inflation pressure matches
the recommended pressure on the tire
and loading information label, no further
adjustment is necessary. If the pressure
is low, add air until you reach the
recommended amount.
If you overfill the tire, release air by
pushing on the metal stem in the
center of the tire valve. Recheck the
tire pressure with the tire gage. Be
sure to put the valve caps back on the
valve stems. They help prevent leaks by
keeping out dirt and moisture.

Maintenance
WARNING
• Inspect your tires frequently for
proper inflation as well as wear and
damage. Always use a tire pressure
gauge.
• Tires with too much or too little
pressure wear unevenly causing poor
handling, loss of vehicle control,
and sudden tire failure leading to
accidents, injuries, and even death.
The recommended cold tire pressure
for your vehicle can be found in this
manual and on the tire label located
on the driver’s side center pillar.
• Worn tires can cause accidents.
Replace tires that are worn, show
uneven wear, or are damaged.
• Remember to check the pressure
of your spare tire. HYUNDAI
recommends that you check the
spare every time you check the
pressure of the other tires on your
vehicle.
Tire rotation
To equalize tread wear, it is
recommended that the tires be rotated
every 10,000 km (6,200 miles) or sooner
if irregular wear develops.
During rotation, check the tires for
correct balance.
When rotating tires, check for uneven
wear and damage. Abnormal wear
is usually caused by incorrect tire
pressure, improper wheel alignment,
out-of-balance wheels, severe braking
or severe cornering. Look for bumps
or bulges in the tread or side of tire.
Replace the tire if you find either of
these conditions. Replace the tire if
fabric or cord is visible. After rotation,
be sure to bring the front and rear tire
pressures to specification and check lug
nut tightness.
Refer to “Tire and wheels” in chapter 2.

i Information
Rotate radial tires that have an
asymmetric tread pattern only from front
to rear and not from right to left.
WARNING
• Do not use the compact spare tire for
tire rotation.
• Do not mix bias ply and radial ply
tires under any circumstances.
This may cause unusual handling
characteristics that could result in
death, severe injury, or property
damage.
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
Improper wheel weights can damage
your vehicle’s aluminum wheels. Use
only approved wheel weights.

OEN076053OEN076053
Tread wear indicatorTread wear indicator
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 1.6 mm (1/16 inch) 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.
NOTICE
When replacing the tires, recheck and
tighten the wheel nuts after driving
about 1,000 km (620 miles). If the
steering wheel shakes or the vehicle
vibrates while driving, the tire is out of
balance. Align the tire balance. If the
problem is not solved, we recommend
that you contact an authorized
HYUNDAI dealer.
WARNING
Replacing tires
To reduce the chance or serious or fatal
injuries from an accident caused by tire
failure or loss of vehicle control:
• Replace tires that are worn, show
uneven wear, or are damaged.
Worn tires can cause loss of braking
effectiveness, steering control, and
traction.
• Do not drive your vehicle with too
little or too much pressure in your
tires. This can lead to uneven wear
and tire failure.
• When replacing tires, never mix
radial and bias-ply tires on the
same car. You must replace all tires
(including the spare) if moving from
radial to bias-ply tires.
• It is best to replace all four tires at the
same time. If that is not possible, or
necessary, then replace the two front
or two rear tires as a pair. Replacing
just one tire can seriously affect your
vehicle’s handling.
• Using tires and wheel other than the
recommended sizes could cause
unusual handling characteristics and
poor vehicle control, resulting in a
serious accident.
• Wheels that do not meet HYUNDAI’s
specifications may fit poorly and
result in damage to the vehicle or
unusual handling and poor vehicle
control.
• The works by comparing the speed of
the wheels. Tire size can affect wheel
speed. When replacing tires, all 4
tires must use the same size originally
supplied with the vehicle. Using tires
of a different size can cause the ABS
(Anti-lock Brake System) and ESC
(Electronic Stability Control) to work
irregularly. (if equipped)

10-57
10
Compact spare tire replacement
(if equipped)
A compact spare tire has a shorter tread
life than a regular size tire. Replace
it when you can see the tread wear
indicator bars on the tire. The replaced
compact spare tire should be the same
size and design tire as the one provided
with your new vehicle and should be
mounted on the same compact spare
tire wheel. The compact spare tire is not
designed to be mounted on a regular
size wheel, and the compact spare tire
wheel is not designed to mount a regular
size tire.
Wheel replacement
When replacing the metal wheels for any
reason, make sure the new wheels are
equivalent to the original factory units in
diameter, rim width and offset.
WARNING
A wheel that is not the correct size may
adversely affect wheel and bearing life,
braking and stopping abilities, handling
characteristics, ground clearance,
body-to-tire clearance, snow chain
clearance, speedometer and odometer
calibration, headlight aim and bumper
height.
Tire traction
Tire traction can be reduced if you drive
on worn tires, tires that are improperly
inflated or on slippery road surfaces.
Tires should be replaced when tread
wear indicators appear. Slow down
whenever there is rain, snow or ice on
the road, to reduce the possibility of
losing control of the vehicle.

Wheel size designation
Wheels are also marked with important
information that you need if you ever
have to replace one. The following
explains what the letters and numbers in
the wheel size designation mean.
Example wheel size designation:
5.0JX14
5.0 - Rim width in inches.
J - Rim contour designation.
14 - Rim diameter in inches
Tire speed ratings
The chart below lists many of the
different speed ratings currently being
used for passenger car tires. The speed
rating is part of the tire size designation
on the sidewall of the tire. This symbol
corresponds to that tire’s designed
maximum safe operating speed.
Speed Rating
SymbolMaximum Speed
S180 km/h (112 mph)
T190 km/h (118 mph)
H 210 km/h (130 mph)
V 240 km/h (149 mph)
W 270 km/h (168 mph)
Y 300 km/h (186 mph)

3. Checking tire life (TIN : Tire
Identification Number)
Any tires that are over 6 years old,
based on the manufacturing date,
(including the spare tire) should be
replaced by new ones. You can find
the manufacturing date on the tire
sidewall (possibly on the inside of
the wheel), displaying the DOT Code.
The DOT Code is a series of numbers
on a tire consisting of numbers and
English letters. The manufacturing date
is designated by the last four digits
(characters) of the DOT code.
DOT : XXXX XXXX OOOO
The front part of the DOT means a plant
code number, tire size and tread pattern
and the last four numbers indicate week
and year manufactured.
For example:
DOT XXXX XXXX 2220 represents that
the tire was produced in the 22th week
of 2020.
WARNING
Tire age
Tires degrade over time, even when
they are not being used.
Regardless of the remaining tread, it is
recommended that tires generally 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 could cause sudden
tire failure, which could lead to a loss
of control and an accident involving
serious injury or death.

10-61
10
Traction - AA, A, B & C
The traction grades, from highest to
lowest, are AA, A, B and C. Those grades
represent the tire’s ability to stop on wet
pavement measured under controlled
conditions on specified government
test surfaces of asphalt and concrete.
A tire marked C may have poor traction
performance.
WARNING
The traction grade assigned to this tire
is based on straight-ahead braking
traction tests, and does not include
acceleration, cornering, hydroplaning,
or peak traction characteristics.
Temperature -A, B & C
The temperature grades are A (the
highest), B, and C, representing the tire’s
resistance to the generation of heat
and its ability to dissipate heat when
tested under controlled conditions on a
specified indoor laboratory test wheel.
Sustained high temperature can cause
the material of the tire to degenerate
and reduce tire life, and excessive
temperature can lead to sudden tire
failure. Grades B and A represent higher
levels of performance on the laboratory
test wheel than the minimum required
by law.
WARNING
Tire temperature
The temperature grade for this tire is
established for a tire that is properly
inflated and not overloaded. Excessive
speed, underinflation, or excessive
loading, either separately or in
combination, can cause heat build-up
and sudden tire failure. This can cause
loss of vehicle control and serious
injury or death.
Low aspect ratio tire
(if equipped)
Low aspect ratio tires, whose aspect
ratio is lower than 50, are provided for
sporty looks.
Because the low aspect ratio tires are
optimized for handling and braking, it
may be more uncomfortable to ride in
and there is more noise compare with
normal tires.

A vehicle’s electrical system is protected
from electrical overload damage by
fuses.
This vehicle has 2 fuse panels, one
located in the driver’s side panel bolster,
the other in the engine compartment.
If any of your vehicle’s lights,
accessories, or controls do not work,
check the appropriate circuit fuse. If a
fuse has blown, the element inside the
fuse will be melted or broken.
If the electrical system does not work,
first check the driver’s side fuse panel.
Before replacing a blown fuse, turn the
engine and all switches off, and then
disconnect the negative battery cable.
Always replace a blown fuse with one of
the same rating.
If the replacement fuse blows, this
indicates an electrical problem.
Avoid using the system involved and
we recommend that all inspect an
authorized HYUNDAI dealer.
i Information
Three kinds of fuses are used: blade type
for lower amperage rating, cartridge
type, and multi fuse for higher amperage
ratings.
WARNING
NEVER replace a fuse with anything but
another fuse of the same rating.
• A higher capacity fuse could cause
damage and possibly cause a fire.
• Do not install a wire or aluminum
foil instead of the proper fuse -
even as a temporary repair. It may
cause extensive wiring damage and
possibly a fire.
NOTICE
Do not use a screwdriver or any other
metal object to remove fuses because
it may cause a short circuit and damage
the system.

We recommend that you consult an
authorized HYUNDAI dealer to replace
most vehicle light bulbs. It is difficult
to replace vehicle light bulbs because
other parts of the vehicle must be
removed before you can get to the bulb.
This is especially true for removing the
headlight assembly to get to the bulb(s).
Removing/installing the headlight
assembly can result in damage to the
vehicle.
WARNING
Prior to replacing a light, depress the
foot brake, move the shift lever into the
N (Neutral, for Automatic transmission
vehicle) or neutral (for manual
transmission vehicle), apply the parking
brake, place the ignition switch in the
LOCK/OFF position, and take the key
with you when leaving the vehicle to
avoid sudden movement of the vehicle
and to prevent possible electric shock.
Be aware the bulbs may be hot and may
burn your fingers.
NOTICE
Be sure to replace the burned-out bulb
with one of the same wattage rating.
Otherwise, it may cause damage to the
fuse or electric wiring system.
i Information
The headlight and tail lamp lenses could
appear frosty if the vehicle is washed after
driving or the vehicle is driven at night
in wet weather. This condition is caused
by temperature difference between the
lamp inside and outside and, it does not
indicate a problem with your vehicle.
When moisture condenses in the lamp,
it will be removed after driving with the
headlight on. The removable level may
differ depending on lamp size, lamp
position and environmental condition.
However, if moisture is not removed, we
recommend that your vehicle is inspected
by an authorized HYUNDAI dealer.
