2014 Hyundai Sonata flat tire

Maintenance
Checking tire inflation pres-
sure
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 look-
ing 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 firm-
ly 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 adjust-
ment is necessary. If the pressure is
low, add air until you reach the rec-
ommended 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 mois-
ture.
•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 caus-
ing poor handling, loss of vehi-
cle control, and sudden tire
failure leading to accidents,
injuries, and even death. The
recommended cold tire pres-
sure for your vehicle can be
found in this manual and on
the tire label located on the dri-
ver's side center pillar.
•Wo r n t i r e s c a n c a u s e a c c i -
dents. Replace tires that are
worn, show uneven wear, or
are damaged.
•Remember to check the pres-
sure of your spare tire.
HYUNDAI recommends that
you check the spare every
time you check the pressure
of the other tires on your vehi-
cle.

Maintenance
Wheel replacement
When replacing the metal wheels for
any reason, make sure the new
wheels are equivalent to the original
factor y units in diameter, rim width
and offset.
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. To reduce the possibility of
losing control, slow down whenever
there is rain, snow or ice on the road.
Tire maintenance
In addition to proper inflation, correct
wheel alignment helps to decrease
tire wear. If you find a tire is worn
unevenly, have your dealer check the
wheel alignment.
When you have new tires installed,
make sure they are balanced. This
will increase vehicle ride comfort and
tire life. Additionally, a tire should
always be rebalanced if it is removed
from the wheel.
Tire sidewall labeling
This information identifies and
describes the fundamental charac-
teristics of the tire and also provides
the tire identification number (TIN)
for safety standard cer tification. The
TIN can be used to identify the tire in
case of a recall.

A wheel that is not the correct
size may adversely affect wheel
and bearing life, braking and
stopping abilities, handling
characteristics, ground clear-
ance, body-to-tire clearance,
snow chain clearance,
speedometer and odometer cal-
ibration, headlamp aim and
bumper height.

4. Tire ply composition and
material
The number of layers or plies of rub-
ber-coated fabric are in the tire. Tire
manufacturers also must indicate the
materials in the tire, which include
steel, nylon, polyester, and others.
The letter "R" means radial ply con-
struction; the letter "D" means diago-
nal or bias ply construction; and the
letter "B" means belted-bias ply con-
struction.
5. Maximum permissible infla-
tion pressure
This number is the greatest amountof air pressure that should be put inthe tire. Do not exceed the maximumpermissible inflation pressure. Referto the Tire and Loading Informationlabel for recommended inflationpressure.
6. Maximum load rating
This number indicates the maximum
load in kilograms and pounds that
can be carried by the tire. When
replacing the tires on the vehicle,
always use a tire that has the same
load rating as the factory installed
tire.
7. Uniform tire quality grading
Quality grades can be found where
applicable on the tire sidewall
between tread shoulder and maxi-
mum section width.
For example:
TREADWEAR 200
TRACTION AA
TEMPERATURE A
Tr e a d w e a r
The tread wear grade is a compara-
tive rating based on the wear rate of
the tire when tested under controlled
conditions on a specified govern-
ment test course. For example, a tire
graded 150 would wear one-and-a-
half times (1½) as well on the gov-
ernment course as a tire graded 100.
The relative performance of tires
depends upon the actual conditions
of their use, however, and may
depart significantly from the norm
because of variations in driving
habits, service practices and differ-
ences in road characteristics and cli-
mate.
These grades are molded on the
side-walls of passenger vehicle tires.
The tires available as standard or
optional equipment on your vehicles
may vary with respect to grade.

Maintenance
Traction - AA, A, B & C
The traction grades, from highest to
lowest, are AA, A, B and C. Those
grades represent the tires ability to
stop on wet pavement as measured
under controlled conditions on spec-
ified government test surfaces of
asphalt and concrete. A tire marked
C may have poor traction perform-
ance.
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 condi-
tions 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 perform-
ance on the laboratory test wheel
than the minimum required by the
law.
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 possible sudden
tire failure. This can cause loss
of vehicle control and serious
injury or death.
WARNING
The traction grade assigned to
this tire is based on straight-
ahead braking traction tests,
and does not include accelera-
tion, cornering, hydroplaning,
or peak traction characteristics.
WARNING

Headlamp and front fog lamp
aiming (For Europe)
Headlamp aiming
1. Inflate the tires to the specified
pressure and remove any loads
from the vehicle except the driver,
spare tire, and tools.
2. The vehicle should be placed on a
flat floor.
3. Draw vertical lines (Vertical lines
passing through respective head
lamp centers) and a horizontal line
(Horizontal line passing through
center of head lamps) on the
screen.
4. With the headlamp and battery in
normal condition, aim the head-
lamps so the brightest portion falls
on the horizontal and vertical
lines.
5. To aim the low beam left or right,
turn the driver clockwise or coun-
terclockwise. To aim the low beam
up or down, turn the driver clock-
wise or counterclockwise.
To aim the high beam up or down,
turn the driver clockwise or coun-
terclockwise.
Front fog lamp aiming
The front fog lamp can be aimed as
the same manner of the headlamps
aiming.
With the front fog lamps and battery
in normal condition, aim the front fog
lamps.
To aim the front fog lamp up or down,
turn the driver clockwise or counter-
clockwise.
