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:
6.0J X 15
6.0 - Rim width in inches.
J - Rim contour designation.
15 - Rim diameter in inches.
7 \ U H V S H H G U D W L Q J V
The chart below lists many of the
different speed ratings currently being
used for passenger vehicle tyres. The
speed rating is part of the tyre size
designation on the sidewall of the tyre.
This symbol corresponds to that tyre’s
designed maximum safe operating
speed.
Speed Rating
SymbolMaximum Speed
S112 mph (180 km/h)
T118 mph (190 km/h)
H 130 mph (210 km/h)
V 149 mph (240 km/h)
W 168 mph (270 km/h)
Y 186 mph (300 km/h)
3. Checking tyre life (TIN : Tyre
Identification Number)
Any tyres that are over six years old,
based on the manufacturing date,
(including the spare tyre) should be
replaced by new ones. You can find
the manufacturing date on the tyre
sidewall (possibly on the inside of
the wheel), displaying the DOT Code.
The DOT Code is a series of numbers
on a tyre 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 shows a plant
code number, tyre size and tread pattern
and the last four numbers indicate week
and year manufactured.
For example:
DOT XXXX XXXX 1521 represents that the
tyre was produced in the 15th week of
2021.
4. Tyre ply composition and
material
The number of layers or plies of
rubber-coated fabric in the tyre. Tyre
manufacturers also must indicate the
materials in the tyre, which include steel,
nylon, polyester, and others. The letter
“R” means radial ply construction; the
letter “D“ means diagonal or bias ply
construction; and the letter “B” means
belted-bias ply construction.

5. Maximum permissible inflation
pressure
This number is the greatest amount
of air pressure that should be put in
the tyre. Do not exceed the maximum
permissible inflation pressure. Refer to
the Tyre and Loading Information label
for recommended inflation pressure.
6. Maximum load rating
This number indicates the maximum
load in kilograms and pounds that can
be carried by the tyre. When replacing
the tyres on the vehicle, always use a
tyre that has the same load rating as the
factory installed tyre.
7. Uniform tyre quality grading
Quality grades can be found where
applicable on the tyre sidewall between
tread shoulder and maximum section
width.
For example:
TREADWEAR 200
TRACTION AA
TEMPERATURE A
7 U H D G Z H D U
The tread wear grade is a comparative
rating based on the wear rate of the tyre
when tested under controlled conditions
on a specified government test course.
For example, a tyre graded 150 would
wear one-and-a-half times (1½) as well
on the government course as a tyre
graded 100. The relative performance of tyres
depends upon the actual conditions
of their use, however, and may depart
significantly from the norm due to
variations in driving habits, service
practices and differences in road
characteristics and climate.
These grades are molded on the
sidewalls of passenger vehicle tyres. The
tyres available as standard or optional
equipment on your vehicle may vary
with respect to grade.
7 U D F W L R Q $ $ $ % &
The traction grades, from highest to
lowest, are AA, A, B and C. Those grades
represent the tyre’s ability to stop on wet
pavement as measured under controlled
conditions on specified government
test surfaces of asphalt and concrete. A
tyre marked C may have poor traction
performance.
WARNING
The traction grade assigned to this tyre
is based on straight-ahead braking
traction tests, and does not include
acceleration, cornering, hydroplaning,
or peak traction characteristics.

We recommend that you consult with a
HYUNDAI authorised repairer 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.

3. Draw vertical lines (Vertical lines
passing through respective head
light centres) and a horizontal line
(Horizontal line passing through
centre of head lamps) on the screen.
4. With the headlight and battery in
normal condition, aim the headlights
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
counterclockwise. To aim the low
beam up or down, turn the driver
clockwise or counterclockwise.
To aim the high beam up or
down, turn the driver clockwise or
counterclockwise.Front fog light aiming (if equipped)
OBC3090042
The front fog light can be aimed as the
same manner of the head lights aiming.
With the front fog lights and battery
normal condition, aim the front fog
lights. To aim the front fog light up
or down, turn the driver clockwise or
counterclockwise.
