!!
Always be sure the tire is cold before
inflating to the recommended pressure.
A cold tire means the vehicle has been
sitting for 3 hours and driven for less
than 1 mile in that 3 hour period.
NOTE:
o Do not use any tire sealant if your
vehicle is equipped with a Tire
Pressure Monitoring System. The
liquid sealant can damage the tire
pressure sensors.
o In order for the system to correctly
monitor tires for under-inflation,
there should be a total of exactly 4
sensors fitted to each of the four
driven wheel positions. There
should be no other sensors in the
vehicle include spare tire since
this could cause the system to
monitor the wrong sensors.WARNING - TPMS
o The TPMS cannot alert you to se-
vere and sudden tire damage
caused by external factors.
o If you feel any vehicle instability,
immediately take your foot off the
accelerator and slowly move to a
safe position off the road.
WARNING:
Tampering with, modifying, or dis-
abling the Tire Pressure Monitoring
System (TPMS) components may
interfere with the system's ability to
warn the driver of low tire pressure
conditions and/or TPMS malfunc-
tions. Tampering with, modifying,
or disabling the Tire Pressure Moni-
toring System (TPMS) components
may void the warranty for that por-
tion of the vehicle.This device complies with Part 15 of
the FCC rules.
Operation is subject to the following two
conditions:
1. This device may not cause harmful
interference, and
2. This device must accept any inter-
ference received, including interfer-
ence that may cause undesired op-
eration.
WARNING:
Changes or modifications not ex-
pressly approved by the party re-
sponsible for compliance could void
the user’s authority to operate the
equipment.

WHAT TO DO IN AN EMERGENCY
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.

D060D01A-AAT3. Loosen Wheel Nuts
The wheel nuts should be loosened
slightly before raising the car. To loosen
the nuts, turn the wrench handle coun-
terclockwise. When doing this, be sure
that the socket is seated completely
over the nut so it cannot slip off. For
maximum leverage, position the wrench
so the handle is to the left as shown in
the drawing. Then, while holding the
wrench near the end of the handle, push
down on it with steady pressure. Do not
remove the nuts at this time. Just
loosen them about one-half turn.

Raise the car high enough so that the
fully inflated spare tire can be installed.
To do this, you will need more ground
clearance than is required to remove
the flat tire.
D060F02E-AAT5. Raising the Car
After inserting a wrench bar into the
wheel nut wrench, install the wrench bar
into the jack as shown in the drawing.
To raise the vehicle, turn the wheel nut
wrench clockwise. As the jack begins
to raise the vehicle, double check that
it is properly positioned and will not slip.
If the jack is on soft ground or sand,
place a board, brick, flat stone or other
object under the base of the jack to
keep it from sinking.WARNING:
Do not get under the car when it is
supported by the jack! This is very
dangerous as the vehicle could fall
and cause serious injury or death.
No one should stay in the car while
the jack is being used.

D060G02Y-AAT6. Changing Wheels
Loosen the wheel nuts and remove
them with your fingers. Slide the wheel
off the studs and lay it flat so it cannot
roll away. To put the wheel on the hub,
pick up the spare tire, line up the holes
with the studs and slide the wheel onto
them. If this is difficult, tip the wheel
slightly and get the top hole in the wheel
lined up with the top stud. Then jiggle
the wheel back and forth until the wheel
can be slid over the other studs.
D060G01NF-A
!
WARNING:
Wheels and wheel covers may have
sharp edges. Handle them carefully
to avoid possible severe injury. Be-
fore putting the wheel into place, be
sure that there is nothing on the hub
or wheel (such as mud, tar, gravel,
etc.) that interferes with the wheel
from fitting solidly against the hub.
D060G02NF
!
If there is, remove it. If there is not
good contact on the mounting sur-
face between the wheel and hub, the
wheel nuts could come loose and
cause the loss of a wheel. Loss of a
wheel may result in loss of control of
the vehicle. This may cause serious
injury or death.WARNING:

D060I01E-AAT8. Lower Vehicle and Tighten Nuts
Lower the car to the ground by turning
the wheel nut wrench counterclock-
wise.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.

D060H02O-AAT7. Reinstall Wheel Nuts
To reinstall the wheel, 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 di-
ameter ends directed inward. Jiggle the
tire to be sure it is completely seated,
then tighten the nuts as much as pos-
sible with your fingers again.

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 Wheel nut tightening torque:

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.
IF YOUR VEHICLE MUST BE
TOWEDD080A01O-GATIf your vehicle has to be towed, it should be done
by your Hyundai dealer or a commercial tow
truck service. This will help assure that your
vehicle is not damaged in towing. Also, profes-
sionals are generally aware of local laws gov-
erning 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 local laws are observed.
It is recommended that your vehicle be towed
with a wheel lift and dollies or flatbed equipment
with all the wheels off the ground.
!
CAUTION:
o Your vehicle can be damaged if towed
incorrectly!
o Be sure the transaxle is in neutral.
o When the engine will not start, be sure
the steering is unlocked by placing the
key in the "ACC" position.
