FOR MORE INFORMATION
ABOUT YOUR HYUNDAIG250A01A-AATIf you desire additional information about
maintaining and servicing your Hyundai,
you may purchase a factory Shop Manual
at your Hyundai dealer's parts department.
This is the same manual used by
dealership technicians and while it is highly
technical it can be useful in obtaining a
better understanding of your car and how
it works.
HEADLIGHT AIMING ADJUST-
MENTG290A03O-AATBefore performing aiming adjustment,
make sure of the following.
1. Keep all tires inflated to the correct
pressure.
2. Place the vehicle on level ground and
press the front bumper & rear bumper
down several times.
Place vehicle at a distance of 118 in.
(3m) from the test wall.
3. See that the vehicle is unloaded (except
for full levels of coolant, engine oil and
fuel, and spare tire, jack, and tools).
Have the driver or equivalent weight
placed in driver's seat.
4. Clean the headlight lenses and turn on
the headlights (Low beam).
5. Open the hood.
G290A01NF-A
Vertical
aiming
!
6. Draw a vertical line (through the center
of each headlight beam pattern) and a
horizontal line (through the center of
each headlight beam pattern) on the
aiming screen measured from ground
to center mark on headlight lens.
7. Adjust the right side of each cut-off line
of the low beam to the horizontal line
with a phillips screwdriver - VERTICAL
AIMING.
WARNING:
Never attempt to adjust the horizontal
alignment of your headlights. Horizontal
aiming must be adjusted by an
authorized Hyundai dealer to avoid
incorrect alignment that will reduce the
effectiveness of your headlights.

6. Maximum load rating
This number indicates the maximum
load in kilograms and pounds that
can be carried by the tire. When
replacing the tires on the vehicle,
always use a tire that has the same
load rating as the factory installed
tire.
7. Uniform Tire Quality Grading
(UTQG):
Tire manufacturers are required to
grade tires based on three perfor-
mance factors: treadwear, traction
and temperature resistance. For more
information, see Uniform Tire Qual-
ity Grading on page 8-14.
I030D01JM-AATTIRE TERMINOLOGY AND DEFINI-
TIONS
Air Pressure: The amount of air inside
the tire pressing outward on the tire. Air
pressure is expressed in pounds per
square inch (psi) or kilopascal (kPa).
Accessory Weight: This means the
combined weight of optional accesso-
ries. Some examples of optional ac-
cessories are, automatic transmission,
power seats, and air conditioning.
Aspect Ratio: The relationship of a
tire's height to its width.
Belt: A rubber coated layer of cords that
is located between the plies and the
tread. Cords may be made from steel or
other reinforcing materials.
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 op-
tional equipment including the maxi-
mum 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 compliance with the U.S. Depart-
ment of Transportation motor vehicle
safety standards. The DOT code in-
cludes the Tire Identification Number
(TIN), an alphanumeric designator which
can also identify the tire manufacturer,
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.

8CONSUMER INFORMATION, REPORTING SAFETY DEFECTS & BINDING ARBITRATION OF WARRANTY CLAIMS8
Occupant Distribution: Designated
seating positions.
Outward Facing Sidewall: The side of
an asymmetrical tire that has a particu-
lar side that faces outward when
mounted on a vehicle. The side of the
tire that contains a whitewall, bears
white lettering or bears manufacturer,
brand and or model name molding that
is higher or deeper than the same mold-
ings on the other sidewall of the tire.
Passenger (P-Metric) Tire: A tire used
on passenger cars and some light duty
trucks and multipurpose vehicles.
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 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 maxi-
mum speed at which a tire can operate.
Traction: The friction between the tire
and the road surface. The amount of
grip provided.
Tread: The portion of a tire that comes
into contact with the road.
Treadwear Indicators: Narrow bands,
sometimes called "wear bars," that show
across the tread of a tire when only 2/32
inch of tread remains.
UTQGS: Uniform Tire Quality Grading
Standards, a tire information system
that provides consumers with ratings
for a tire's traction, temperature and
treadwear. Ratings are determined by
tire manufacturers using government
testing procedures. The ratings are
molded into the sidewall of the tire. Intended Outboard Sidewall: The side
of an asymmetrical tire, that must al-
ways face outward when mounted on a
vehicle.
Kilopascal (kPa): The metric unit for
air pressure.
Load Index: An assigned number rang-
ing from 1 to 279 that corresponds to
the load carrying capacity of a tire.
Maximum Inflation Pressure: The
maximum air pressure to which a cold
tire may be inflated. The maximum air
pressure is molded onto the sidewall.
Maximum Load Rating: The load rat-
ing for a tire at the maximum permis-
sible inflation pressure for that tire.
Maximum Loaded Vehicle Weight:
The sum of curb weight; accessory
weight; vehicle capacity weight; and
production options weight.
Normal Occupant Weight: The num-
ber of occupants a vehicle is designed
to seat multiplied by 150 pounds (68
kg).

CONSUMER INFORMATION, REPORTING SAFETY DEFECTS & BINDING ARBITRATION OF WARRANTY CLAIMS
9
Vehicle Capacity Weight: The number
of designated seating positions multi-
plied 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:
That 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: A label permanently
attached to a vehicle showing the origi-
nal equipment tire size and recom-
mended inflation pressure.
I050A04Y-AATTIRE CHAINS
Tire chains, if necessary, should be
installed on the front wheels. Be sure
that the chains are the proper size and
that they are installed in accordance
with the manufacturer's instructions.
To minimize tire and chain wear, do not
continue to use tire chains when they
are no longer needed.
I040B01JM-AATALL SEASON TIRES
Hyundai specifies all season tires on
some models to provide good perfor-
mance for use all year round, including
snowy and icy road conditions. All sea-
son tires are identified by ALL SEASON
and/or M+S (Mud and Snow) on the tire
sidewall. Snow tires have better snow
traction than all season tires an may be
more appropriate in some areas.I040A01O-AATSNOW TIRES
If you equip your car with snow tires,
they should be the same size and have
the same load capacity as the original
tires. Snow tires should be installed on
all four wheels; otherwise, poor han-
dling may result.Snow tires should carry 4 psi (28 kPa)
more air pressure than the pressure
recommended for the standard tires on
the tire label on the driver's side of the
center pillar , or up to the maximum
pressure shown on the tire sidewall,
whichever is less.
Do not drive faster than 75 mph (120
km/h) when your car is equipped with
snow tires.
