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!
C190A01S-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:
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.
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.

C190F02O-AATTrailer 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. Trailer towing requires more fuel than normal
conditions.
3. To maintain engine braking efficiency, do not
tow a trailer with the transaxle engaged in
overdrive gear.
4. Always secure items in the trailer to prevent
load shift while driving.
5. 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.
6. 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.
7. 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 Park. In addition, place wheel
chocks at each of the trailer's tires.
!
4. The gross combination weight (sum of
your vehicle weight plus its load and the
total trailer weight) must not exceed the
following.

8. 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.
9. During your trip, check occasionally to be
sure that the load is secure, and that the
lights and any trailer brakes are still working.
10.Avoid jerky starts, sudden acceleration or
sudden stops.
11.Avoid sharp turns and rapid lane changes.
12.Avoid holding the brake pedal down too long
or too frequently. This could cause the brakes
to overheat, resulting in reduced braking
efficiency.
13.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.
14.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.
15.If the transaxle shifts frequently while going
up a hill, shift down one gear.
NOTE:When towing check transaxle fluid more
frequently.
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.

NOTE:
o Overloading your vehicle may
cause damage. Repairs would not
be covered by your warranty. Do
not overload your vehicle.
o Using heavier suspension com-
ponents to get added durability
might not change your weight rat-
ings. Ask your dealer to help you
load your vehicle the right way.
The label will help you decide how much
cargo and installed equipment your
vehicle can carry.
If you carry items inside your vehicle –
like suitcases, tools, packages, or any-
thing else – they move as fast as the
vehicle goes. If you have to stop or turn
quickly, or if there is a crash, the items
will keep going and can cause an injury
if they strike the driver or a passenger.
!
WARNING:
Items you carry inside your vehicle
can strike and injure people in a
sudden stop or turn, or in a crash.
o Put things in the cargo area of
your vehicle. Try to spread the
weight evenly.
o Never stack items, like suitcases,
inside the vehicle above the tops
of the seats.
o Do not leave an unsecured child
restraint in your vehicle.
o When you carry something inside
the vehicle, secure it.
o Do not drive with a seat folded
down unless necessary.

D060J02O-AATAfter Changing Wheels
If you have a tire gauge, remove the
valve cap and check the air pressure. If
the pressure is lower than recom-
mended, drive slowly to the nearest
service station and inflate to the correct
pressure. If it is too high, adjust it until
HSM5014
Then position the wrench as shown in
the drawing and tighten the wheel nuts.
Be sure the socket is seated com-
pletely over the nut. Do not stand on the
wrench handle or use an extension pipe
over the wrench handle.
Go around the wheel tightening every
other nut until they are all tight. Then
double-check each nut for tightness.
After changing wheels, have a techni-
cian tighten the wheel nuts to their
proper torque as soon as possible.
HSM4019
Wheel nut tightening torque:
Steel wheel & aluminium alloy wheel:
65-80 lb.ft (900-1,100 kg.cm)it is correct. Always reinstall the valve
cap after checking or adjusting tire
pressure. If the cap is not replaced, air
may leak from the tire. If you lose a
valve cap, buy another and install it as
soon as possible.
After you have changed wheels, al-
ways secure the flat tire in its place and
return the jack and tools to their proper
storage locations.

F060D01A-AATo Fuel Lines, Fuel Hoses and Connec-
tionsCheck the fuel lines, fuel hoses and connec-
tions for leakage and damage. Have a trained
technician replace any damaged or leaking
parts immediately.F060B01A-AATo Drive BeltsInspect all drive belts for evidence of cuts,
cracks, excessive wear or oil saturation and
replace if necessary. Drive belts should be
checked periodically for proper tension and
adjusted as necessary.
F060M01A-AATo Engine Oil and FilterThe engine oil and filter should be changed at the
intervals specified in the maintenance sched-
ule. If the car is being driven in severe condi-
tions, more frequent oil and filter changes are
required.F060C01A-AATo Fuel FilterA clogged filter can limit the speed at which the
vehicle may be driven, damage the emission
system and cause hard starting. If an exces-
sive amount of foreign matter accumulates in
the fuel tank, the filter may require replacement
more frequently.
After installing a new filter, run the engine for
several minutes, and check for leaks at the
connections. Fuel filters should be installed by
trained technicians.
F060F01O-AATo Vacuum HosesInspect the surface of hoses for evidence of
heat and/or mechanical damage. Hard and
brittle rubber, cracking, tears, cuts, abrasions,
and excessive swelling indicate deterioration.
Particular attention should be paid to examine
those hose surfaces nearest to high heat
sources, such as the exhaust manifold.
Inspect the hose routing to assure that the
hoses do not come in contact with any heat
source, sharp edges or moving component
which might cause heat damage or mechanical
wear. Inspect all hose connections, such as
clamps and couplings, to make sure they are
secure, and that no leaks are present. Hoses
should be replaced immediately if there is any
evidence of deterioration or damage.

G050C01A-AATTo Check the Coolant LevelThe coolant level can be seen on the side of the
plastic coolant reservoir. The level of the cool-
ant should be between the "L" and "F" lines on
the reservoir when the engine is cool. If the level
is below the "L" mark, add engine coolant to
bring it up between "L" and "F". If the level is low,
inspect for coolant leaks and recheck the fluid
level frequently. If the level drops again, visit
your Hyundai dealer for an inspection and
diagnosis of the reason.
G050C01OG050D02A-AAT
To Change the Engine CoolantThe engine coolant should be changed at those
intervals specified in the vehicle maintenance
schedule in Section 5.
G050D01O
CAUTION:
Engine coolant can damage the finish of
your car. If you spill engine coolant on the
car, wash it off thoroughly with clean water.
1. Park the car on level ground, set the park-
ing brake and remove the radiator cap when
cool.2. Turn the radiator cap counterclockwise with-
out pressing down on it, until it stops. This
relieves any pressure remaining in the cool-
ing system. And remove the radiator cap by
pushing down and turning counterclock-
wise.
3. Be sure your drain receptacle is in place.
Open the drain cock on the radiator. Allow all
the engine coolant to drain from the cooling
system, then securely close the drain cock.
4. Check Section 9 for the capacity of the
cooling system in your car. Then, following
the manufacturer's directions on the engine
coolant container, add the appropriate quan-
tity of coolant to the radiator.
5. Fill the radiator with clean demineralized or
distilled water. Continue to add clean dem-
ineralized or distilled water in small quantities
until the fluid level stays up in the radiator
neck.
