C190B01S-AATTrailer HitchesSelect the proper hitch and ball combination,
making sure that its location is compatible with
that of the trailer or vehicle being towed.
Use a quality non-equalizing hitch which distrib-
utes the tongue load uniformly throughout the
chassis.
The hitch should be bolted securely to the car
and installed by a qualified technician. DO NOT
USE A HITCH DESIGNED FOR TEMPORARY
INSTALLATION AND NEVER USE ONE THAT
ATTACHES ONLY TO THE BUMPER.C190C01Y-AATTrailer BrakesIf your trailer is equipped with a braking system,
make sure it conforms to federal and/or local
regulations and that it is properly installed and
operating correctly.NOTE:If you tow a trailer or vehicle, your car will
require more frequent maintenance due to
the additional load. See Maintenance Under
Severe Usage Conditions" on page 5-6.
TRAILER OR VEHICLE TOWING!
C190A01TG-AATIf you are considering towing with your car, you
should first check with your State's Department
of Motor Vehicles to determine their legal re-
quirements.
Since laws vary from State to State the require-
ments for towing trailers, cars, or other types of
vehicles or apparatus may differ. Ask your
Hyundai dealer for further details before towing.
CAUTION:
o Do not do any towing with your car
during its first 1,200 miles (2,000 km) in
order to allow the engine to properly
break in. Failure to heed this caution may
result in serious engine or transaxle
damage.
o When towing a trailer, be sure to consult
your Hyundai dealer for further informa-
tion on additional requirements such as
a towing kit, etc.
USE OF LIGHTSC180A01A-AATCheck your lights regularly for correct opera-
tion and always keep them clean. When driving
during the day in conditions of poor visibility, it
is helpful to drive with headlights on low beam.
This enables you to be seen, as well as to see.

C190D01S-AATSafety ChainsShould the hitch connection between your car
and the trailer or vehicle you are towing fail, the
trailer or vehicle could wander dangerously
across other lanes of traffic and ultimately leave
the roadway. To eliminate this potentially dan-
gerous situation, safety chains, attached be-
tween your car and the trailer or towed vehicle,
are required in most states.
CAUTION:
o Never connect a trailer brake system
directly to the vehicle brake system.
o When towing a trailer on steep grades (in
excess of 6%) pay close attention to the
engine coolant temperature gauge to
ensure the engine does not overheat. If
the needle of the coolant temperature
gauge moves across the dial towards
"H" (HOT), pull over and stop as soon as
it is safe to do so, and allow the engine
to idle until it cools down. You may
proceed once the engine has cooled
sufficiently.

2. The total gross vehicle weight with trailer
must not exceed the Gross Vehicle
Weight Rating (GVWR) shown on the
vehicle identification plate (see page 8-
2). The total gross vehicle weight is the
combined weight of the vehicle, driver,
all passengers and their luggage, cargo,
hitch, trailer tongue load and other op-
tional equipment.

Tongue Load Total Trailer Weight
o Keep the tongue load 10% of the total trailer
load.
o Tongue load
o Tongue loads can be increased or de-
creased by re-distributing the load in the
trailer.
This can be verified by checking the total
weight of the loaded trailer and then checking
the load on the tongue.

x 100 = 10% (MAX)
Total trailer weight
NOTE:1. Never load the trailer with more weight in
the back than in the front. About 60% of
the trailer load should be in the front half
on the trailer and the remaining 40% in
the rear.

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 af-
fected 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 val-
ues in the chart below.
WARNING:
o Improperly loading your vehicle and
trailer can seriously affect its steering
and braking performance causing a
crash which could cause serious injury
or death.
o Towing a trailer affects vehicle handling
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 driv-
ing up and down hills. 3. The front or rear axle weight must not
exceed the Gross Axle Weight Rating
(GAWR) shown on the vehicle identifi-
cation plate (see page 8-2). It is possible
that your towing package does not ex-
ceed 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.

8. When parking your car and trailer, especially
on a hill, be sure to follow all the normal
precautions. Turn your front wheel into the
curb, set the parking brake firmly, and put the
transaxle in 1st or Reverse (manual) or Park
(automatic). In addition, place wheel chocks
at each of the trailer's tires.
9. If the trailer has electric brakes, start your
vehicle and trailer moving, and then apply the
trailer brake controller by hand to be sure the
brakes are working. This lets you check
your electrical connection at the same time.
10.During your trip, check occasionally to be
sure that the load is secure, and that the
lights and any trailer brakes are still working.
11.Avoid jerky starts, sudden acceleration or
sudden stops.
12.Avoid sharp turns and rapid lane changes.
13.Avoid holding the brake pedal down too long
or too frequently. This could cause the brakes
to overheat, resulting in reduced braking
efficiency.
14.When going down a hill, shift into a lower gear
and use the engine braking effect.
When ascending a long grade, downshift the
transaxle to a lower gear and reduce speed
to reduce chances of engine overloading
and/or overheating.
CAUTION:
If overheating should occur when towing,
(the temperature gauge reads near red zone),
taking the following action may reduce or
eliminate the problem.
1. Turn off the air conditioner.
2. Reduce highway speed.
3. Select a lower gear when going uphill.
4. While in stop and go traffic, place the
gear selector in park or neutral and idle
the engine at a higher speed.

15.If you have to stop while going uphill, do not
hold the vehicle in place by pressing on the
accelerator. This can cause the automatic
transaxle to overheat. Use the parking brake
or footbrake.NOTE:When towing check transaxle fluid more
frequently.

The tire label located on the driver's
side of the center pillar outer panel
gives the original tire size, cold tire
pressures recommended for your ve-
hicle, the number of people that can be
in your vehicle and vehicle capacity
weight.
Vehicle capacity weight:
880 lbs (400 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 in-
cludes the tongue load.Seating capacity:
Total: 5 persons
(Front seat: 2 persons,
Rear seat: 3 persons)
Seating capacity is the maximum num-
ber of occupants including a driver,
your vehicle may carry. However the
seating capacity may be reduced based
upon the weight of all of the occupants,
and the weight of the cargo being car-
ried or towed.
Do not overload the vehicle as there is
a limit to the total weight, or load limit
including occupants and cargo, the
vehicle can carry.
Towing capacity:
Towing capacity is the maximum trailer
weight including its cargo weight, your
vehicle can tow. See the section "Trailer
or Vehicle Towing" for specifications
about the trailer weight.Cargo capacity:
The cargo capacity of your vehicle will
increase or decrease depending on the
weight and the number of occupants
and the tongue load, if your vehicle is
equipped with a trailer.
Steps for Determining Correct Load
Limit
(1)Locate the statement "The combined
weight of occupants and cargo should
never exceed XXX pounds'' on your
vehicle's placard.
(2)Determine the combined weight of
the driver and passengers that will be
riding in your vehicle.
(3)Subtract the combined weight of the
driver and passengers from XXX
kilograms or XXX pounds.

(4)The resulting figure equals the avail-
able amount of cargo and luggage
load capacity. For example, if the
"XXX" amount equals 1400 lbs, and
there will be five 150 lb. passengers
in your vehicle, the amount of avail-
able cargo and luggage load capac-
ity is 650 lbs. (1400-750 (5 x 150) =
650 lbs.)
(5)Determine the combined weight of
luggage and cargo being loaded on
the vehicle. That weight may not
safely exceed the available cargo
and luggage load capacity calcu-
lated in Step 4.
(6)If your vehicle will be towing a trailer,
load from your trailer will be trans-
ferred to your vehicle. Consult this
manual to determine how this re-
duces the available cargo and lug-
gage load capacity of your vehicle.

Refer to your vehicle's tire and loading
information label for specific informa-
tion about your vehicle's capacity weight
and seating positions. The combined
weight of the driver, passengers and
cargo should never exceed your
vehicle's capacity weight.
C190G03JM-AATCompliance LabelThe compliance label is located on the
driver's side of the center pillar outer
panel.
The label shows the maximum allow-
able weight of the fully loaded vehicle.
This is called the GVWR (Gross Ve-
hicle Weight Rating). The GVWR in-
cludes the weight of the vehicle, all
occupants, fuel and cargo.

WARNING:
o Overloading your vehicle can
cause heat buildup in your
vehicle's tires and possible tire
failure that could lead to a crash.
o Overloading your vehicle can
cause increased stopping dis-
tances that could lead to a crash.
o A crash resulting from poor han-
dling vehicle damage, tire failure,
or increased stopping distances
could result in serious injury or
death.
!
This label also tells you the maximum
weights that can be supported by the
front and rear axles, called 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. Your dealer can
help you with this. Be sure to spread out
your load equally on the left and right
sides of the centerline.
WARNING:
o Never exceed the GVWR for your
vehicle, the GAWR for either the
front or rear axle and vehicle ca-
pacity weight. Exceeding these rat-
ings can cause an accident or
vehicle damage. You can calcu-
late the weight of your load by
weighing the items (or people)
before putting them in the vehicle.
Be careful not to overload your
vehicle.WARNING:
o Do not load your vehicle any
heavier than the GVWR, either the
maximum front or rear GAWR and
vehicle capacity weight. If you do,
parts, including tires on your ve-
hicle can break, and it can change
the way your vehicle handles and
braking ability. This could cause
you to lose control and crash.
Also, overloading can shorten the
life of your vehicle.
