Driving your vehicle
Two labels on your driver's door sill
show how much weight your vehicle
was designed to carry: the Tire and
Loading Information Label and the
Certification Label.
Before loading your vehicle, familiar-
ize yourself with the following terms
for determining your vehicle’s weight
ratings, from the vehicle's specifica-
tions and the Certification Label:
Base Curb Weight
This is the weight of the vehicle
including a full tank of fuel and all
standard equipment. It does not
include passengers, cargo, or option-
al equipment.
Vehicle Curb Weight
This is the weight of your new vehicle
when you picked it up from your deal-
er plus any aftermarket equipment.
Cargo Weight
This figure includes all weight added
to the Base Curb Weight, including
cargo and optional equipment. GAW (Gross Axle Weight)
This is the total weight placed on
each axle (front and rear) - including
vehicle curb weight and all payload.
GAWR (Gross Axle Weight Rating)
This is the maximum allowable
weight that can be carried by a single
axle (front or rear). These numbers
are shown on the Certification Label.
The total load on each axle must
never exceed its GAWR.
GVW (Gross Vehicle Weight)
This is the Base Curb Weight plus
actual Cargo Weight plus passen-
gers.
GVWR (Gross Vehicle Weight
Rating)
This is the maximum allowable
weight of the fully loaded vehicle
(including all options, equipment,
passengers and cargo). The GVWR
is shown on the Certification Label
located on the driver’s door sill.
Tire Loading Information Label
The label located on the driver's door
sill gives the original tire size, cold
tire pressures recommended for your
vehicle, the number of people that
can be in your vehicle and vehicle
capacity weight.
Vehicle capacity weight
849 lbs. (385 kg)
Vehicle capacity weight is the maxi-
mum combined weight of occupants
and cargo. If your vehicle is equipped
with a trailer, the combined weight
includes the tongue load.

Certification label
The certification label is located on
the driver’s door sill at the center pil-
lar and shows the maximum allow-
able weight of the fully loaded vehi-
cle. This is called the GVWR (Gross
Vehicle Weight Rating). The GVWR
includes the weight of the vehicle, all
occupants, fuel and cargo.
This label also tells you the maxi-
mum weight that can be supported
by the front and rear axles, called
Gross Axle Weight Rating (GAWR).The total weight of the vehicle,
including all occupants, accessories,
cargo, and trailer tongue load must
not exceed the Gross Vehicle Weight
Rating (GVWR) or the Gross Axle
Weight Rating (GAWR). To find out
the actual loads on your front and
rear axles, you need to go to a weigh
station and weigh your vehicle. Be
sure to spread out your load equally
on both sides of the centerline.
OBH059070
Overloading
Never exceed the GVWR for
your vehicle, the GAWR for
either the front or rear axle
and vehicle capacity weight.
Exceeding these ratings can
affect your vehicle’s handling
and braking ability, and cause
an accident.
Do not overload your vehicle.
Overloading your vehicle can
cause heat buildup in your
vehicle’s tires and possible
tire failure, increased stop-
ping distances and poor vehi-
cle handling-all of which may
result in a crash.

Maintenance
Check Tire Inflation Pressure
Check your tires, including the spare
tire, once a month or more.
How to check
Use a good quality tire pressure
gauge to check tire pressure. You
can not tell if your tires are properly
inflated simply by looking at them.
Radial tires may look properly inflat-
ed when they are under-inflated.
Remove the valve cap from the tire
valve stem. Press the tire gauge 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 pressure. Make sure to
put the valve caps back on the valve
stems. Without the valve cap, dirt or
moisture could get into the valve
core and cause air leakage. If a valve
cap is missing, install a new one as
soon as possible.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 gauge. Be
sure to put the valve caps back on
the valve stems. Without the valve
cap, dirt or moisture could get into
the valve core and cause air leakage.
If a valve cap is missing, install a new
one as soon as possible.
Under-inflation results in
excessive wear, poor handling
and reduced fuel economy.
Wheel deformation is also
possible. Keep your tire pres-
sures at the proper levels. If a
tire frequently needs refilling,
have it checked by an author-
ized HYUNDAI dealer.
Over-inflation produces a
harsh ride, excessive wear at
the center of the tire tread,
and a greater possibility of
damage from road hazards.
CAUTION

Maintenance
Bead
The tire bead contains steel wires
wrapped by steel cords that hold the
tire onto the rim.
Bias Ply Tire
A pneumatic tire in which the plies
are laid at alternate angles less than
90 degrees to the centerline of the
tread.
Cold Tire Pressure
The amount of air pressure in a tire,
measured in pounds per square inch
(psi) or kilopascals (kPa) before a tire
has built up heat from driving.
Curb Weight
This means the weight of a motor
vehicle with standard and optional
equipment including the maximum
capacity of fuel, oil and coolant, but
without passengers and cargo.
DOT Markings
A code molded into the sidewall of a
tire signifying that the tire is in com-
pliance with the U.S. Department of
Transportation motor vehicle safety
standards. The DOT code includes
the Tire Identification Number (TIN),
an alphanumeric designator which
can also identify the tire manufactur-
er, production plant, brand and date
of production.
GVWR
Gross Vehicle Weight Rating
GAWR FRT
Gross Axle Weight Rating for the
Front Axle.
GAWR RR
Gross Axle Weight Rating for the
Rear axle.
Intended Outboard Sidewall
The side of an asymmetrical tire, that
must always face outward when
mounted on a vehicle.
Kilopascal (kPa)
The metric unit for air pressure.
Light truck(LT) tire
A tire designated by its manufacturer
as primarily intended for use on light-
weight trucks or multipurpose pas-
senger vehicles.
Load ratings
The maximum load that a tire is rated
to carry for a given inflation pressure.
Load Index
An assigned number ranging from 1
to 279 that corresponds to the load
carrying capacity of a tire.
