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.

when only 2/32 inch of tread
remains.
UTQGS: The Uniform Tire Quality
Grading Standards is the information
of traction, temperature and tread
abrasion. A rating is measured by a
tire manufacturer in accordance with
the government-specified testing
procedure. The rating information is

Vehicle Capacity Weight: The mul-
tiplication of the designated occu-
pant seat number by 150 pounds (68
kg) plus the loading weight.
Vehicle Maximum Load on the
Tire: Loading capacity for an individ-
ual tire. The curb and accessory
weights plus the maximum occupant
and loading weights.
Vehicle Normal Load on the Tire:
Loading capacity for an individual
axle. The sum of the curb, accessory,
and normal occupant weights is
divided by 2.
Vehicle Placard: A label, perma-
nently attached to a vehicle, to indi-
cate the original equipment tire size
and the recommended inflation pres-
sure.
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

Maintenance07
Tire chains
Tire chains, if necessary, should be
installed on the drive wheels (rear
wheels).
Make sure that the chains are
installed in accordance with the man-
ufacturer's instructions.
To minimize the abrasion of tires and
chains, do not use the chains, when
unnecessary.
Radial-ply tires
Radial-ply tires provide longer tread
life, better road hazard resistance
and smoother riding at a high speed.
The radial-ply tires used on this vehi-
cle are of belted construction, and
are to improve your driving and han-
dling. Radial-ply tires have the same
loading capacity as the bias-ply or
bias-belted tires of the same size.
Inflate the radial-ply tires to the same
recommended inflation pressure. It is
not recommended to attempt a
cross-combination of radial-ply tires
and bias-ply(or bias-belted) tires on
the same vehicle. Any cross-combi-
nation of radial-ply and bias-ply(or
bias-belted) tires on one vehicle will
seriously deteriorate vehicle han-
dling. The best rule to follow is:
Identical radial-ply tires should
always be used for a set of four tires.
A tire, which is driven for a long peri-
od of time, is more susceptible to
irregular tread abrasion. It is very
important to rotate tires, at the inter-
val instructed in this chapter, to use it
up to its potential tread life. Any cut
and puncture on a radial-ply tire is
repairable, only when it is on the
tread, because of the side wall flex-
ing. Consult your tire dealer for a
radial-ply tire repair.

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.
