Ply
A layer of rubber-coated parallel cords.
Pneumatic tire
A mechanical device made of rubber,
chemicals, fabric and steel or other
materials, that, when mounted on an
automotive wheel provides the traction
and contains the gas or fluid that
sustains the load.
Pneumatic options weight

production options weighing over 5 lb.
(2.3 kg) in excess of the standard items
which they replace, not previously
considered in curb weight or accessory
weight, including heavy duty breaks, ride
levelers, roof rack, heavy duty battery,
and special trim.
Recommended Inflation Pressure
Vehicle manufacturer’s recommended
tire inflation pressure as shown on the
tire placard.
Radial Ply Tire
A pneumatic tire in which the ply cords
that extend to the beads are laid at 90
degrees to the centerline of the tread.
Rim
A metal support for a tire and upon
which the tire beads are seated.
Sidewall
The portion of a tire between the tread
and the bead.
Speed Rating
An alphanumeric code assigned to a tire
indicating the maximum speed at which
a tire can operate.
Traction
The friction between the tire and
the road surface. The amount of grip
provided.
Tread

Ratings are determined by tire
manufacturers using government testing
procedures. The ratings are molded into
the sidewall of the tire.
Vehicle Capacity Weight

positions multiplied by 150 lbs. (68 kg)
plus the rated cargo and luggage load.
Vehicle Maximum Load on the Tire
Load on an individual tire due to curb
and accessory weight plus maximum
occupant and cargo weight.
Vehicle Normal Load on the Tire
Load on an individual tire that is
determined by distributing to each axle
its share of the curb weight, accessory
weight, and normal occupant weight and
dividing by 2.
Vehicle Placard

Normal Blown
OTM078035
A vehicle’s electrical system is protected
from electrical overload damage by
fuses.
This vehicle has 2 (or 3) fuse panels, one
located in the driver’s side panel bolster,
the other in the engine compartment
near the battery.
If any of your vehicle’s lights,
accessories, or controls do not work,
check the appropriate circuit fuse. If a
fuse has blown, the element inside the
fuse will be melted or broken.
If the electrical system does not work,
first check the driver’s side fuse panel.
Before replacing a blown fuse, turn the
engine and all switches off, and then
disconnect the negative battery cable.
Always replace a blown fuse with one of
the same rating.
If the replacement fuse blows, this
indicates an electrical problem.
Avoid using the system involved and
immediately consult an authorized
HYUNDAI dealer.
WARNING
NEVER replace a fuse with anything but
another fuse of the same rating.
• A higher capacity fuse could cause
damage and possibly cause a fire.
• Do not install a wire or aluminum
foil instead of the proper fuse -
even as a temporary repair. It may
cause extensive wiring damage and
possibly a fire.
NOTICE
Do not use a screwdriver or any other
metal object to remove fuses because
it may cause a short circuit and damage
the system.
