C190F01Y-GATTrailer or Vehicle Towing Tips1. Before towing, check hitch and safety
chain connections as well as proper
operation of the trailer running lights,
brake lights, and turn signals.
2. Always drive your vehicle at a moderate
speed. (Less than 60 mph)
3. Trailer towing requires more fuel than
normal conditions.
4. To maintain engine braking efficiency
and electrical charging performance,
do not tow a trailer with the transaxle in
fifth gear (manual transaxle).
5. Always secure items in the trailer to
prevent load shift while driving.
6. Check the condition and air pressure of
all tires on the trailer and your car. Low
tire pressure can seriously affect the
handling. Also check the spare tire.
7. The vehicle/trailer combination is more
affected by crosswind and buffeting.
When being passed by a large vehicle,
keep a constant speed and steer straight
ahead. If there is too much wind
buffeting, slow down to get out of the
other vehicle's air turbulence.

CAUTION:
The following specifications are recom-
mended when towing a trailer. The loaded
trailer weight cannot safely exceed the
values in the chart below.
WARNING:
o Improperly loading your vehicle and
trailer can seriously affect its steer-
ing and braking performance causing
a crash which could cause serious
injury or death.
o Towing a trailer affects vehicle han-
dling and braking.
o Drive more slowly when towing a trailer
and allow more distance when
braking.
o Be careful when driving in slippery
and windy conditions.
o Be careful when turning and while
driving up and down hills. 3. The front or rear axle weight must not
exceed the Gross Axle Weight Rating
(GAWR) shown on the vehicle identi-
fication plate (see page 8-2). It is
possible that your towing package
does not exceed the GVWR but
exceeds the GAWR. Improper trailer
loading and/or too much luggage in
the trunk can overload the rear axle.
Redistribute the load and check the
axle weight again.

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).

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.
