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 dangerous
situation, safety chains, attached between
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.

Gross Axle WeightGross Vehicle
Weight2. 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 optional
equipment.
C190E01NF-AATTrailer Weight Limit
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
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.

8. When parking your car and trailer, es-
pecially 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, down-
shift the transaxle to a lower gear and
reduce speed to reduce chances of
engine overloading and/or overheat-
ing.
CAUTION:
If overheating should occur when tow-
ing, (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 over-
heat. Use the parking brake or
footbrake.NOTE:When towing check transaxle fluid more
frequently.

34WHAT TO DO IN AN EMERGENCY
IF THE ENGINE OVERHEATS
!!
!
WARNING:
While the engine is running, keep hair,
hands and clothing away from moving
parts such as the fan and drive belts to
prevent injury.
5. If the water pump drive belt is broken or
engine coolant is leaking out, stop the
engine immediately and call the nearest
Hyundai dealer for assistance.
WARNING:
Do not remove the radiator cap when the
engine is hot. This can allow coolant to be
blown out of the opening and cause se-
rious burns.6. If you cannot find the cause of the
overheat-ing, wait until the engine
temperature has returned to normal.
Then, if coolant has been lost, carefully
add coolant to the reservoir (page 6-9)
to bring the fluid level in the reservoir up
to the halfway mark.
7. Proceed with caution, keeping alert for
further signs of overheating. If
overheating happens again, call a
Hyundai dealer for assistance.
CAUTION:
Serious loss of coolant indicates there is
a leak in the cooling system and this
should be checked as soon as possible
by a Hyundai dealer.
D030A02A-AATIf your temperature gauge indicates over-
heating, you experience a loss of power, or
hear loud pinging or knocking, the engine
is probably too hot. If this happens, you
should:
1. Pull off the road and stop as soon as it
is safe to do so.
2. Place the gear selector lever in "P"
(automatic) or neutral (manual
transaxle) and set the parking brake. If
the air conditioning is on, turn it off.
3. If engine coolant is running out under
the car or steam is coming out from the
hood, stop the engine. Do not open the
hood until the coolant has stopped
running or the steaming has stopped. If
there is no visible loss of engine coolant
and no steam, leave the engine running
and check to be sure the engine cooling
fan is operating. If the fan is not running,
turn the engine off.
4. Check to see if the water pump drive belt
is missing. If it is not missing, check to
see that it is tight. If the drive belt seems
to be satisfactory, check for coolant
leaking from the radiator, hoses or under
the car. (If the air conditioning had been
in use, it is normal for cold water to be
draining from it when you stop).

CHANGING A FLAT TIRE
IF YOU HAVE A FLAT TIRE
D060A01A-AATThe procedure described on the follow-
ing pages can be used to rotate tires as
well as to change a flat tire. When
preparing to change a flat tire, check to
be sure the gear selector lever is in "P"
(automatic transaxle) or reverse gear
(manual transaxle) and that the parking
brake is set, then:
D050A01A-AATIf a tire goes flat while you are driving:
1. Take your foot off the accelerator pedal
and let the car slow down while driving
straight ahead. Do not apply the brakes
immediately or attempt to pull off the
road as this may cause a loss of
control. When the car has slowed to
such a speed that it is safe to do so,
brake carefully and pull off the road.
Drive off the road as far as possible
and park on firm, level ground. If you
are on a divided highway, do not park
in the median area between the two
traffic lanes.
2. When the car is stopped, turn on your
emergency hazard flashers, set the
parking brake and put the transaxle in
"P" (automatic) or reverse (manual
transaxle).
3. Have all passengers get out of the car.
Be sure they all get out on the side of
the car that is away from traffic.
4. Change the tire according to the in-
structions provided as follows.

CLEANING THE INTERIORE040A01A-AATTo Clean the Vinyl UpholsteryTo clean the vinyl upholstery, first remove
loose dirt and dust with a vacuum cleaner.
Then apply a solution of mild soap or
detergent and water using a clean sponge
or soft cloth. Allow this to stay on the surface
to loosen the dirt, then wipe with a clean
damp sponge or cloth. If all the dirt stains
are not removed, repeat this procedure
until the upholstery is clean. Do not use
gasoline, solvent, paint thinner or other
strong cleaners.
E030E01A-AATMaintaining BumpersSpecial precautions must be observed to
preserve the appearance of the bumpers
on your Hyundai. They are:
o Be careful not to spill battery electrolyte
or hydraulic brake fluid on the bumpers.
If you do, wash it off immediately with
clean water.
o Be gentle when cleaning the bumper
sur-faces. They are made of soft plastic
and the surface can be damaged if
mistreated. Do not use abrasive
cleaners. Use warm water and mild
soap or car-washing solution.
o Do not expose the bumpers to high tem-
peratures. For example, if you have
your car repainted, do not leave the
bumpers on the car if the car is going to
be placed in a high-temperature paint
booth.
E030D01A-AATWhen to Wax AgainYou should polish and wax the car again
when water no longer beads on a clean
surface but spreads out over a larger area.E030C01A-AATPolishing and WaxingAlways wash and dry the car before
polishing or waxing or using a combination
cleaner and wax. Use a good quality
commercial product and follow the
manufacturer's directions on the container.
Polish and wax the bright trim pieces as
well as the paint.E030B01A-AATSpot CleaningDon't use gasoline, strong solvents or cor-
rosive cleaning agents. These can
damage the finish of the car. To remove
road tar, use turpentine on a clean, soft
cloth. Be gentle.
To remove dead insects or tree sap, use
warm water and mild soap or car-washing
solution. Soak the spot and rub gently. If
the paint has lost its luster, use a
commercial car-cleaning polish.
