Securing the child Restraint seat with
the "ISOFIX" system
Some child seat manufacturers make safety
seats that are labeled as ISOFIX or ISOFIX-
compatible child seats. These seats include two
rigid or webbing mounted attachments that
connect to two ISOFIX anchors at specific
seating positions in your vehicle. This type of
child seat eliminates the need to use seat belts
to attach the child seat for forward-facing child
seats.
ISOFIX anchors have been provided in your
vehicle. The ISOFIX anchors are located in the
left and right outboard rear seating positions.
Their locations are shown in the illustration.There is no ISOFIX anchor provided for the
center rear seating position.
WARNING:o Do not install a child safety seat at the
center of the rear seat using the vehicle's
ISOFIX anchors. The ISOFIX anchors are
only provided for the left and right out-
board rear seating positions. Do not
misuse the ISOFIX anchors by attempt-
ing to attach a child sefety seat in the
middle of the rear seat position to the
ISOFIX anchors. In a crash, the child seat
ISOFIX attachments may not be strong
enough to secure the child restraint seat
properly in the center of the rear seat and
may break, causing serious injury or
death.
o Do not mount more than one child re-
straint to a single tether or to a child
restraint lower anchorage point. the
improper increased load may cause the
anchorage points or tether anchor to
break, causing serious injury or death.
o Attach the ISOFIX or ISOFIX-compatible
child seat only to the appropriate loca-
tions shown.
o Always follow the installation and use
instructions provided by the manufac-
turer of the child restraint.
B230F01E
The ISOFIX anchors are located between the
seatback and the seat cushion of the rear seat
left and right outboard seating positions.
Follow the child seat manufacturer's instruc-
tions to properly install safety seats with ISOFIX
or ISOFIX-compatible attachments.
Once you have installed the ISOFIX child re-
straint seat, assure that the seat is properly
attached to the ISOFIX and tether anchors.
Also, test the safety seat before you place the
child in it. Tilt the seat from side to side. Also try
to tug the seat forward. Check to see if the
anchors hold the seat in place.

17TRAILER OR VEHICLE TOWING
C190A02S-AAT
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 require-
ments 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.
!
C190B01S-AAT
Trailer Hitches
Select the proper hitch and ball combination,
making sure that it's 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.
C190C03S-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 5-6.
C190D01S-AAT
Safety Chains
Should 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 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.

!WARNING:Improperly loading your car and trailer can
seriously affect its steering and braking
performance causing a crash which could
cause serious injury or death.
C190F01S-AAT
Trailer 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 normal
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, 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, occasionally check to be
sure that the load is secure, and that the
lights and any trailer brakes are still work-
ing.
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 over-
loading 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.
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.

To reinstall the wheel cover, hold it on the studs,
put the wheel nuts on the studs and tighten them
finger tight. The nuts should be installed with
their small diameter ends directed inward. Jiggle
the tire to be sure it is completely seated, then
tighten the nuts as much as possible with your
fingers again.

D060J01E-AAT
After Changing Wheels
Lower the car to the ground by turning the wheel
nut wrench counterclockwise. Then position
the wrench as shown in the drawing and tighten
the wheel nuts. Be sure the socket is seated
completely 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 technician tighten the wheel nuts to their
proper torque as soon as possible.
Wheel nut tightening torque:Steel wheel & aluminium alloy wheel:
65-80 lb.ft (900-1,100 kg.cm)If you have a tire gauge, remove the valve cap
and check the air pressure. If the pressure is
lower than recommended, drive slowly to the
nearest service station and inflate to the correct
pressure. If it is too high, adjust it until it is correct.
Always reinstall the valve cap after checking or
adjusting tire pressure. If the cap is not re-
placed, 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, always secure
the flat tire in its place in the trunk and return the
jack and tools to their proper storage locations.
