Tire Pressure Monitoring
System
WARNING Over-inflation or under-inflation can
reduce tire life, adversely affect vehicle
handling, and lead to sudden tire failure
that may cause loss of vehicle control
resulting in an accident.

Each tire, including the spare (if
provided), should be checked monthly
when cold and inflated to the inflation
pressure recommended by the vehicle
manufacturer on the vehicle placard or
tire inflation pressure label. (If your
vehicle has tires of a different size than
the size indicated on the vehicle placard
or tire inflation pressure label, you should
determine the proper tire inflation
pressure for those tires.)
As an added safety feature, your vehicle
has been equipped with a tire pressure
monitoring system (TPMS) that
illuminates a low tire pressure telltale
when one or more of your tires is
significantly under-inflated. Accordingly,
when the low tire pressure telltale
illuminates, you should stop and check
your tires as soon as possible, and inflate
them to the proper pressure. Driving on a
significantly under-inflated tire causes
the tire to overheat and can lead to tire
failure.
Under-inflation also reduces fuel
efficiency and tire tread life, and may
affect the vehicle’s handling and stopping
ability.
Please note that the TPMS is not a
substitute for proper tire maintenance,
and it is the driver’s responsibility to
maintain correct tire pressure, even if
under-inflation has not reached the level
to trigger illumination of the TPMS low
tire pressure telltale.
Your vehicle has also been equipped with
a TPMS malfunction indicator to indicate when the system is not operating
properly. The TPMS malfunction indicator
is combined with the low tire pressure
telltale. When the system detects a
malfunction, the telltale will flash for
about one minute and then remain
continuously illuminated. This sequence
will continue upon subsequent vehicle
start-ups as long as the malfunction
exists.
When the malfunction indicator is
illuminated, the system may not be able
to detect or signal low tire pressure as
intended. TPMS malfunctions may occur
for a variety of reasons, including the
installation of replacement or alternate
tires or wheels on the vehicle that prevent
the TPMS from functioning properly.
Always check the TPMS malfunction
telltale after replacing one or more tires or
wheels on your vehicle to ensure that the
replacement or alternate tires and wheels
allow the TPMS to continue to function
properly.

Tire Care
For proper maintenance, safety, and
maximum electric energy economy,
you must always maintain
recommended tire inflation
pressures and stay within the load
limits and weight distribution
recommended for your vehicle.
OJK010021
All specifications (sizes and
pressures) can be found on a label
attached to the driver’s side center
pillar.
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 one mile (1.6
km).
Warm tires normally exceed
recommended cold tire pressures by
4 to 6 psi (28 to 41 kPa). Do not
release air from warm tires to adjust
the pressure or the tires will be
under-inflated. For recommended
inflation pressure, refer to the “Tires
and Wheels” section in chapter 2.
WARNING • Recommended pressures must be maintained for the best ride,
vehicle handling, and minimum tire
wear.
• Over-inflation or under-inflation can reduce tire life, adversely affect
vehicle handling, and lead to
sudden tire failure that may result
in loss of vehicle control resulting in
a collision.
• Severe under-inflation may lead to severe heat build-up, causing
blowouts, tread separation, and
other tire failures that result in loss
of vehicle control resulting in a
collision. This risk is much higher on
hot days and when driving for a
long time at high speeds.
• Under-inflation may cause excessive wear, poor handling, and
reduced fuel economy. Wheel
deformation is also possible. Keep
your tire pressures at the proper
levels. If a tire frequently needs
refilling, have it inspected by an
authorized HYUNDAI dealer.
• Over-inflation produces a harsh ride, excessive wear at the center of
the tire tread, and a greater
possibility of damage from road
hazards.

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 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 lbs. per
square in. (psi) or kilopascal (kPa).Accessory weight
This means the combined weight of
optional accessories. Some examples
of optional accessories are gear,
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 lbs. per square in. (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.
