Tire rotation
To balance worn-out levels of the tire
tread, rotating the tire positions is
required every 7,500 miles (12,000
km), or sooner, when the irregular
abrasion is detected. While rotating
the positions, correctly balance the
tire positions.
When rotating tires, check for any
uneven abrasion and damage.
Abnormal tire abrasion is usually
caused by improper tire pressure,
tilted wheel alignment, unbalanced
wheels, severe braking or hard cor-
nering. Check for any bump or
bulging from the tire side walls. When
finding one of those, replace you tire.
Replace the tire, when a tire cord
fabric is visible. After rotation, make
sure to properly inflate the tires to the
recommended pressure, as speci-
fied, and check the lug-nut tightness.
Disc brake pads should be inspectedfor any abrasion, whenever rotatingtires.
Information
The front tire size is different from the
rear tire size. So when you rotate tires,
check sizes of the tires and wheels.
Wheel alignment and tire bal-
ance
The wheels are finely aligned and
balanced at the manufacturing facto-
ry in order to ensure the longest tire
life and the best driving performance.
In most cases, you do not need to
realign the wheels. However, when
detecting unusual tire abrasion or
vehicle leaning to one side, the
realignment may be needed. When
your vehicle vibrates on an even sur-
face, while driving, your wheels may
need to be rebalanced.
Improperly overweighted wheel
may damage your vehicle's alu-
minum wheels. Carry only the
appropriate wheel weights.
NOTICE

OBK079038
Without a spare tire
Do not use the compact spare
tire for tire rotation.
Never mix bias-ply tires and radial-ply tires under any cir-
cumstances. This may cause
abnormal handling, possibly
resulting in a death, severe
injury, or property damage.
WARNING

Maintenance
Tire replacement
When a tire unevenly wears out, a
tread wear indicator, in a pattern of a
solid band, appears over the tread.
This indicates that there is less than
1/16 inch (1.6 mm) of tread left.
When finding it, replace the tire.
Do not delay the tire replacement,
until all the indicators appear over
the entire tire tread.
OEN076053
Tread wear indicator
- Replacing tires
To reduce the risk of a serious
or fatal injury, caused by a tire
failure or a loss of vehicle con-
trol, follow the below warnings:
Replace tires, which areseverely worn out, unevenly
wear out, or damaged. Worn-
out tires may degrade the
braking effects, steering con-
trol, and traction.
Do not drive your vehicle with overinflated or underinflated
tires. This may cause uneven
abrasion or a tire failure.
(Continued)
(Continued)
When replacing tires of yourvehicle, never mix radial-ply
tires and bias-ply tires. You
must replace all the tires
(including the spare) when
changing from radial-ply tires
to bias-ply tires.
Tires and wheels in the differ- ent sizes may cause abnormal
handling and poor vehicle
control, resulting in a serious
accident.
Wheels, which do not satisfy the HYUNDAI’s specifications,
may be unfit and result in a
vehicle damage, abnormal
handling and poor vehicle
control.
The ABS operates upon com- paring the wheel speeds. A
tire size determines a wheel
speed. When replacing tires,
all the tires must be in the
same size as the original
ones. Installing tires in a dif-
ferent size may cause irregu-
lar operation of the ABS (Anti-
lock Brake System) and ESC
(Electronic Stability Control).
WARNING

7-47
Maintenance07
Compact spare tire replacement
A compact spare tire has a shorter
tread life than a regular one. Replace
it, when a tread wear indicator is
found. A compact spare tire should
be replaced with the one in the same
size as the original one, and should
be installed over a tire wheel of the
same compact size. A compact
spare tire is not designed to be
installed over a wheel of the regular
size, and a compact spare wheel is
not designed for a tire of the regular
size.
Wheel replacement
When replacing the metal wheels for
any reason, make sure the new
wheels are equivalent to the original
wheel in terms of diameter, rim width
and offset.
Information
The front tire size is different from the
rear one. While rotating tire positions,
check the size of the tires and wheels.
Information
A wheel in the different size may
adversely affect the wheel bearing,
braking, stopping, handling, ground
clearance, body-to-tire clearance,
snow-chain clearance, speedometer,
odometer, headlamp angle and
bumper height.
Tire traction
Tire traction may decrease when
driving with worn-out or improperly-
inflated tires on a slippery surface.
Tires should be replaced, when a
tread wear indicator appears. Slow
down the driving speed to lower the
risk of losing the vehicle control,
when it rains or snows, or when your
vehicle drives on a icy surface.
i
i
The compact spare tire is for
emergency use only. Do not
operate your vehicle on this
compact spare at a speed over
50 mph (80 km/h). The original
tire should be immediately
repaired or replaced to avoid a
spare-tire failure and a possible
personal injury or death.
WARNING

Wheel size designation
Wheels are also marked with impor-
tant specifications. The following
example of the wheel size designa-
tion explains how the letters and
numbers are interpreted.
Example wheel size designation:
8.0JX19
8.0 - Rim width in inches.
J - Rim contour designation.
19 - Rim diameter in inches.
Tire speed ratings
The below chart lists up different
speed ratings for a tire of a passen-
ger vehicle. The speed rating is one
part of the tire size designation,
specified on the tire side wall. Each
symbol represents the maximum
driving speed of a tire.
3. Checking tire life (TIN : TireIdentification Number)
Any tires, which are 6 years or older
from the manufacturing date (includ-
ing the spare tire), should be
replaced with a new one. The manu-
facturing date is written on a tire side
wall (possibly inside of a wheel) in
the DOT Code. The DOT Code is a
series of numbers on a tire, which
consist of numbers and English let-
ters. The manufacturing date is writ-
ten in the last four digits (characters)
of the DOT code.
DOT : XXXX XXXX OOOO
The front part of the DOT are the
plant code, tire size and tread pat-
tern. The last four digits indicate the
manufacturing week and the manu-
facturing year.
For example:
DOT XXXX XXXX 1615 represents
that the tire was produced in the 16th
week of 2015.
S 112 mph (180 km/h)
T 118 mph (190 km/h)
H 130 mph (210 km/h) V 149 mph (240 km/h)Z Above 149 mph (240 km/h)

- Tire age
Tires degrade over time, even
when they are not driven.
Regardless of the remaining
tread, it is recommended to
replace tires every 6 years. Heat
under the hot weather or fre-
quent overloading may acceler-
ate the aging process. Failure to
follow this warning may result
in a sudden tire failure, leading
to a loss of control, accident,
serious injury or death.

4. Tire ply composition andmaterial
There are a number of layers or plies
of rubber-coated fabrics in the tire.
Tire manufacturers indicate the
materials on the tire, such as steel,
nylon and polyester. 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 infla-tion pressure
This number indicates the air pres-
sure limit of the tire. Do not inflate the
tire over the maximum pressure.
Refer to "Tire and Loading
Information Label" for the recom-
mended inflation pressure.
6. Maximum load rating
This number indicates the maximum
loading capacity in kilograms or in
pounds that a tire can carry. When
replacing the tires, always use the
tire of the same load rating as the
original one.
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: TREAD wear 200
TRACTION AA
TEMPERATURE A
Tread wear
The tread wear grade is a compara-
tive rating based on a tire wear-out
rating, which is recorded while being
tested under a controlled condition
on a test course specified by a gov-
ernment. For example, a tire, of
which the tread wear grade is 150,
would wear out one-and-a half times
(1½) faster than a tire graded 100.
The actual tread wear rating
depends on the actual driving condi-
tions. In addition, the actual tread
wear rating may significantly vary
from the tread wear grade due to a
lot of variations, such as driving
habits, maintenance conditions, road
characteristics and climates.
These grades are written on the tire
side wall of a passenger vehicle. The
available tires with the standard or
optional equipment may vary with
respect to this grade.
Traction - AA, A, B & C
The traction grades, from the highest
to the lowest, are AA, A, B and C.
Those grades represent the stopping
performance level of a tire measured
on a wet test surface specified by the
government under a controlled con-
dition. A tire marked with the letter, C,
may have poor traction.
The traction grade of a tire is
based on a braking traction test,
while driving straight ahead. The
test does not include accelerat-
ing, cornering, hydroplaning, or
towing situations.
WARNING

7-51
Maintenance07
Temperature -A, B & C
The temperature grades of a tire are
A, B and C, from the highest to the
lowest, representing the heat-resist-
ing and the heat-dissipating capabili-
ty. A tire is tested under a controlled
condition on a specified indoor labo-
ratory test wheel.
Continuous driving at a high temper-
ature may degenerate the tire mate-
rials and reduce the tire life. Also, a
quick temperature increase may
cause a sudden tire failure. A tire
with the grade C just meets the per-
formance level required by the
Federal Vehicle Safety Standard No.
109, which all tires for a passenger
vehicle must meet. Grades A and B
represent a higher performance level
of a tire on the indoor laboratory test
wheel, above the minimum law
requirement.
Low aspect ratio tire
(if equipped)
A low aspect ratio tire, of which the
aspect ratio is lower than 50, is
designed for a sporty-look vehicle.
The low aspect ratio is to optimize
handling and braking. Thus, it may
be uncomfortable to ride and it may
generate noises, in comparison with
a normal tire.
- 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 side wall of a low aspect
ratio tire is shorter than the nor-
mal one. Thus, the low-aspect
wheel and tire are easily dam-
aged. Follow the below instruc-
tions.
When driving on a rough road or driving off a road, be care-
ful not to damage the tires
and wheels. After driving,
inspect the tires and wheels.
When passing over a pothole, speed bump, manhole, or
curb stone, slowly drive the
vehicle not to damage the
tires and wheels.
When there is an impact on a tire, inspect the tire condition.
Or, contact an authorized
EQUUS dealer.
Inspect the tire condition and pressure every 1,800 miles
(3,000 km) to prevent a tire
damage.

All season tires
HYUNDAI designated some models
of all-season tires to provide good
performance for use all year round,
including snowy and icy road condi-
tions. All-season tires are identified
by ALL SEASON and/or M+S (Mud
and Snow) on the tire side wall.
Snow tires have better snow traction
than all season tires and may be
more appropriate in some areas.
Summer tires
HYUNDAI designated some models
of summer tires to provide superior
performance on dry roads. Summer
tire performance is substantially
reduced in snow and ice. Summer
tires do not have a tire traction rating
mark, M+S (Mud and Snow), on the
tire side wall. Before driving in snowy
or icy conditions, it is recommended
to install snow tires or all-season
tires on all four wheels.
Snow tires
When equipping your vehicle with
snow tires, the tires should be in the
same size and have the same load
capacity as the original ones. Snow
tires should be installed on all four
wheels. Otherwise, it may cause
poor handling. Snow tires should be
more inflated by 4 psi (28 kPa) than
the lesser of the two recommended
pressures - one specified on the tire
label attached to the central pillar on
the driver's side, and the other spec-
ified on the tire side wall.
Do not drive faster than 75 mph (120
km/h) when your car is equipped with
snow tires.
- Snow or ice
When driving on a snowy or icy road, drive slower than 20
mph (30 km/h).
Use the SAE “S” class or wire chains.
When you hear chain-rattling noise, retighten the chain to
avoid its contact with the
vehicle body.
To prevent damage to the vehicle body, retighten the
chains after driving 0.3~0.6
miles (0.5~1.0 km).
Do not use tire chains on a vehicle equipped with alu-
minum wheels. In unavoidable
circumstance, use the wire-
type chains.
Use the wire chains, of which the diameter is less than 0.47
inches (12 mm), to prevent
damage to the chain connect-
ing parts.
WARNING

Maintenance
A vehicle’s electrical system is pro-
tected from a possible electrical
overloading damage by fuses.
This vehicle has 4 fuse panels - two
on the driver’s side, another on the
panel bolster of the passenger's
side, and the other in the engine
compartment.
When any of your lights, acces-
sories, or controls does not operate,
check the appropriate circuit fuse.
When a fuse is out, some elements
may melt inside.
When the electrical system does not
operate, check the fuse panel on the
driver's side first.
Before replacing the fuse, disconnect
the negative battery cable. Always
replace it with a fuse of the same rat-
ing. When the newly-replaced fuse
blows, there may be an electrical
problem. Avoid using any pertinent
systems. Immediately consult an
authorized EQUUS dealer.
Three kinds of fuses are to be used:
a blade type for lower amperage rat-ing, and a cartridge type and a fusiblelink for higher amperage ratings.
Information
The actual fuse, relay panels, and
labels may differ from the equipped
items.

- Fuse replacement
Never replace a fuse with the
one of a different rating.
A higher capacity fuse may cause damage or a fire.
Never use a wire or an alu- minum foil, instead of a prop-
er fuse - even as an emergent
measure. It may damage
extensive wirings and cause a
fire.
WARNING
Do not use a screwdriver or any
other metal object to remove a
fuse. It may cause a short cir-
cuit and damage the system.
