Pre-Tensioner Seat Belt
Your Hyundai vehicle is equipped with driver's
and front passenger's pre-tensioner seat belts.
The purpose of the pre-tensioner is to make
sure that the seat belts fit tightly against the
occupant's body in certain frontal collisions. The
pre-tensioner seat belts can be activated alone
or, where the frontal collision is severe enough,
together with the airbags.
When the vehicle stops suddenly, or if the
occupant tries to lean forward too quickly, the
seat belt retractor will lock into position. In
certain frontal collisions, the pre-tensioner will
activate and pull the seat belt into tighter
contact against the occupant's body.

WARNING:To obtain maximum benefit from a pre-
tensioner seat belt:
1. The seat belt must be worn correctly.
2. The seat belt must be adjusted to the
correct position. mode, the belt will be locked. After installation
of the child restraint system, try to move it in
all directions to be sure the child restraint
system is securely installed. If you need to
tighten the belt, pull more webbing toward the
retractor. When you unbuckle the seat belt
and allow it to retract, the retractor will auto-
matically revert back to its normal seated
passenger emergency locking usage condition.
NOTE:o Before installing the child restraint sys-
tem, read the instructions supplied by the
child restraint system manufacturer.
o If the seat belt does not operate as de-
scribed, have the system checked imme-
diately by your authorized Hyundai dealer.
WARNING:o If the retractor is not in the Automatic
Locking mode, the child restraint system
can move when your vehicle turns or
stops abruptly.
o Do not install any child restraint system
in the front passenger seat. Should an
accident occur and cause the passenger
side airbag to deploy, it could severely
injure or kill an infant or child seated in an
infant or child seat. Therefore, only use a
child restraint system in the rear seat of
your vehicle.

D060J01E-AAT
After Changing Wheels
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 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, always secure
the flat tire in its place in the trunk and return the
jack and tools to their proper storage locations.
D080A01A-AAT
CAUTION:Your car can be damaged if towed incor-
rectly!
HLC4012
If your car has to be towed, it should be done by
your Hyundai dealer or a commercial tow truck
service. This will help assure that your car is not
damaged in towing. Also, professionals are gen-
erally aware of state and local laws governing
towing. In any case, rather than risk damage to
your car, it is suggested that you show this
information to the tow truck operator. Be sure
that a safety chain system is used and that all
state and local laws are observed.

o If the car is being towed with the rear wheels
on the ground, be sure the parking brake is
released.
o If the car is being towed with the front wheels
on the ground, be sure that the transaxle is
in neutral. Also, be sure that the ignition key
is in the "ACC" position. This is necessary to
prevent damage to the steering lock mecha-
nism, which is not designed to hold the front
wheels straight while the car is being towed.

5VEHICLE MAINTENANCE REQUIREMENTS
7EXPLANATION OF SCHEDULED
MAINTENANCE ITEMS
F060D01A-AAT
o Fuel Lines, Fuel Hoses and
Connections
Check the fuel lines, fuel hoses and connec-
tions for leakage and damage. Have a trained
techincian, replace any damaged or leaking
parts immediately.
F060C01A-AATo Fuel Filter
A clogged filter can limit the speed at which the
vehicle may be driven, damage the emission
system and cause hard starting. If an excessive
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 techni-
cians.
F060M01A-AAT
o Engine Oil and Filter
The 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.
F060H01A-AAT
o Air Cleaner Filter
A Genuine Hyundai air cleaner filter is recom-
mended when the filter is replaced.
F060G01A-AAT
o Vapor Hose and Fuel Filler Cap
The vapor hose and fuel filler cap should be
inspected at those intervals specified in the
maintenance schedule. Make sure that a new
vapor hose or fuel filler cap is correctly re-
placed.
F060F01A-AATo Vacuum, Crankcase Ventilation
Hoses
Inspect 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. Par-
ticular 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.
F060B01A-AAT
o Drive Belts
Inspect 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 ad-
justed as necessary.
F060J01A-AAT
o Spark Plugs
Make sure to install new spark plugs of the
correct heat range.

To Change the Coolant
The coolant should be changed at those inter-
vals specified in the vehicle maintenance sched-
ule in Section 5.
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 parking
brake and remove the radiator cap when
cool.
2. 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.
3. 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.
!
4. 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 counterclockwise.
Now fill the radiator with clean demineralized
or distilled water. Continue to add clean
demineralized or distilled water in small quan-
tities until the fluid level stays up in the
radiator neck.
G050D01AG050D02A
5. Start the engine, top off the radiator with
water and then add engine coolant to the
reservoir until the level is between "L" and
"F".
6. Replace the radiator and reservoir caps and
check to be sure the drain cocks are fully
closed and not leaking.

12CHECKING THE TRANSAXLE
FLUID (AUTOMATIC)
!
G110A01E-AAT
Transaxle fluid in the automatic transaxle should
be checked at those intervals specified in the
vehicle maintenance schedule in Section 5.
NOTE:Automatic transaxle fluid is basically a red
color. As driving distance increases, the fluid
color turns darkish red gradually. It is a
normal condition and you should not judge
the need to replace based upon the chang-
ing color.
You must replace the automatic transaxle
fluid in accordance with intervals specified
in the vehicle maintenance schedule in sec-
tion 5.
G110B03A-AATRecommended Fluid
Your Hyundai automatic transaxle is specially
designed to operate with HYUNDAI GENUINE
ATF, DIAMOND ATF SP-III or SK ATF SP-III.
Damage caused by a nonspecified fluid is not
covered by your new vehicle limited warranty.
G110C02A-AAT
Transaxle Fluid Capacity
The fluid capacity of the automatic transaxle is
6.45 U.S. quarts (6.1 liters).
WARNING:The transaxle fluid level should be checked
when the engine is at normal operating tem-
perature. This means that the engine, radia-
tor, exhaust system etc., are very hot. Exer-
cise great care not to burn yourself during
this procedure. 1. Using a wrench of the correct size, loosen
the oil filler plug by turning it counterclock-
wise and remove it with your fingers.
2. Use your finger or suitable tool to feel inside
the hole. The oil level should be at its bottom
edge. If it is not, check for leaks before
adding oil. To refill the transaxle or bring the
oil level up, add oil slowly until it reaches the
proper level. Do not overfill.
3. Replace the plug and washer, screw it in with
your fingers and then tighten securely with
the wrench.
