C190B01S-AAT
Trailer Hitches
Select 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 distributes
the tongue load uniformly throughout the chas-
sis.
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.
C190A02S-AATTRAILER OR VEHICLE TOWING
If 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 re-
quirements for towing trailers, cars, other types
of vehicles, or apparatus may differ. Ask your
Hyundai dealer for further details before towing.
CAUTION: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. Fail-
ure to heed this caution may result in seri-
ous engine or transaxle damage.
C170A01A-AATHIGHER SPEED MOTORING
Pre-Trip Inspections
1. Tires:
Adjust the tire inflation pressures to specifica-
tion. Low tire inflation pressures will result in
overheating and possible failure of the tires.
Avoid using worn or damaged tires which may
result in reduced traction or tire failure.
NOTE:Never exceed the maximum tire inflation
pressure shown on the tires.
2. Fuel, engine coolant and engine oil: High
speed travel consumes 1.5 times more fuel
than urban motoring. Do not forget to check
both engine coolant and engine oil.
3. Drive belt:
A loose or damaged drive belt may result in
overheating of the engine.
C180A01A-AAT
USE OF LIGHTSCheck your lights regularly for correct operation
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.
C190C02S-AATTrailer Brakes
If 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 Un-
der Severe Usage Conditions" on page 5-5.
CAUTION:o Never connect a trailer brake system di-
rectly to the vehicle brake system.
o When towing a trailer on steep grades (in
excess of 12%) 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.

DRIVING YOUR HYUNDAI
2- 15 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, occasionally check 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.
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.
C190F01S-AATTrailer or Vehicle Towing Tips
1. 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 nor-
mal conditions.
4. To maintain engine braking efficiency and
electrical charging performance, do not use
fifth gear (manual transaxle) or overdrive
(automatic 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.
8. When parking your car and trailer, especial-
ly 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.
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 en-
gine at a higher speed.

WHAT TO DO IN AN EMERGENCY
3-2 to follow this procedure, seek qualified as-
sistance. Automobile batteries contain sul-
furic acid. This is poisonous and highly
corrosive. When jump starting, wear protec-
tive glasses and be careful not to get acid on
yourself, your clothing or on the car.
o If you should accidentally get acid on your
skin or in your eyes, immediately remove
any contaminated clothing and flush the
area with clear water for at least 15 minutes.
Then promptly obtain medical attention. If
you must be transported to an emergency
facility, continue to apply water to the affect-
ed area with a sponge or cloth.
o The gas produced by the battery during the
jump-start operation is highly explosive. Do
not smoke or allow a spark or an open flame
in the vicinity.
o The battery being used to provide the jump
start must be 12-volt. If you cannot deter-
mine that it is a 12-volt battery, do not
attempt to use it for the jump start.
o To jump start a car with a discharged bat-
tery, follow this procedure exactly:
1. If the booster battery is installed in another
vehicle, be sure the two vehicles are not
touching.
2. Turn off all unnecessary lights and acces-
sories in both vehicles.
3. Attach the clamps of the jumper cable in the
exact location shown on the previous page.
First, attach one clamp of the jumper cableto the positive (+) post or cable of the dis-
charged battery. Then attach the other end
of the same cable to the positive (+) post or
cable of the booster battery. Next, using the
other cable, attach one clamp to the nega-
tive (-) post or cable of the booster battery.
Then attach the other end of that cable to a
solid metal part of the engine away from the
battery. Do not connect the cable to any
moving part.
4. Start the engine in the car with the booster
battery and let it run for a few minutes. This
will help to assure that the booster battery is
fully charged. During the jumping operation,
run the engine in this vehicle at about 2,000
rpm.
5. Start your engine using the normal starting
procedure. After the engine starts, leave the
jumper cables connected and let the engine
run at fast idle or about 2,000 rpm for sev-
eral minutes.
6. Carefully remove the jumper cables in the
reverse order of attachment.
If you do not know why your battery became
discharged (because the lights were left on,
etc.), have the charging system checked by your
Hyundai dealer.
D030A01A-AATIF THE ENGINE OVERHEATS
If your temperature gauge indicates overheating,
you experience a loss of power, or hear loud
pinging or knocking and the engine is probably
too hot. If this happens and, 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" (auto-
matic), 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
engine 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 engine coolant leak-
ing 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).

WARNING:
Batteries can be dangerous! When working
with batteries, carefully observe the follow-
ing precautions to avoid serious injuries.
The fluid in the battery contains a strong solu-
tion of sulfuric acid, which is poisonous and
highly corrosive. Be careful not to spill it on
yourself or the car. If you do spill battery fluid on
yourself, immediately do the following:
o If battery fluid is on your skin, flush the
affected areas with water for at least 15
minutes and then seek medical assistance.
o If battery fluid is in your eyes, rinse out your
eyes with water and get medical assistance
as soon as possible. While you are being
driven to get medical assistance, continue
to rinse your eyes by using a sponge or soft
cloth saturated with water.
o If you swallow battery fluid, drink a large
quantity of water or milk followed by milk of
magnesia, eat a raw egg or drink vegetable
oil. Get medical assistance as soon as
possible.
