6Changing a tire with TPMS
If you have a flat tire, the Low Tire
Pressure will come on. Have the flat
tire repaired by an authorized
HYUNDAI dealer as soon as possi-
ble or replace the flat tire with the
spare tire.
Each wheel is equipped with a tire
pressure sensor mounted inside the
tire behind the valve stem. You must
use TPMS specific wheels. It is rec-
ommended that you always have
your tires serviced by an authorized
HYUNDAI dealer. Even if you replace the low pressure
tire with the spare tire, the Low Tire
Pressure telltale/TPMS malfunction
indicator will remain on until the low
pressure tire is repaired and placed
on the vehicle.
After you replace the low pressure
tire with the spare tire, the TPMS
malfunction indicator may illuminate
after a few minutes because the
TPMS sensor mounted on the spare
wheel is not initiated.
Once the low pressure tire is reinflat-
ed to the recommended pressure
and installed on the vehicle or the
TPMS sensor mounted on the
replaced spare wheel is initiated by
an authorized HYUNDAI dealer, the
TPMS malfunction indicator and the
low tire pressure telltale will extin-
guish within a few minutes of driving.
If the indicator is not extinguished
after a few minutes of driving, please
visit an authorized HYUNDAI dealer.
CAUTION
If original mounted tire is
replaced with the spare tire, theTPMS sensor on the replacedspare wheel should be initiatedand the TPMS sensor on theoriginal mounted wheel shouldbe deactivated. If the TPMS sen-sor on the original mountedwheel located in the spare tirecarrier still activates, the tirepressure monitoring systemmay not operate properly. Havethe tire with TPMS serviced orreplaced by an authorizedHYUNDAI dealer.
CAUTION
NEVER use a puncture-repair-ing agent to repair and/or inflatea low pressure tire. The tiresealant can damage the tirepressure sensor. If used, youwill have to replace the tire pres-sure sensor.

What to do in an emergency
You may not be able identify a low
tire by simply looking at it. Always
use a good quality tire pressure
gauge to measure the tire's inflation
pressure. Please note that a tire that
is hot (from being driven) will have a
higher pressure measurement than a
tire that is cold.
A cold tire means the vehicle has
been sitting for 3 hours and driven for
less than 1 mile (1.6 km) in that 3
hour period.
Allow the tire to cool before measur-
ing the inflation pressure. Always be
sure the tire is cold before inflating to
the recommended pressure.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 inter-
ference that may cause undesired
operation.
CAUTION
Do not use any tire sealant ifyour vehicle is equipped with aTire Pressure MonitoringSystem. The liquid sealant candamage the tire pressure sen-sors.
WARNING
- Protecting TPMS
Tampering with, modifying, or
disabling the Tire Pressure
Monitoring System (TPMS) com-
ponents may interfere with the
system's ability to warn the driv-
er of low tire pressure condi-
tions and/or TPMS malfunctions.
Tampering with, modifying, or
disabling the Tire Pressure
Monitoring System (TPMS) com-
ponents may void the warranty
for that portion of the vehicle.
WARNING
- TPMS
 The TPMS cannot alert you to severe and sudden tire dam-
age caused by external fac-
tors such as nails or road
debris.
 If you feel any vehicle instabil- ity, immediately take your foot
off the accelerator, apply the
brakes gradually and with
light force, and slowly move to
a safe position off the road.
WARNING
Changes or modifications not
expressly approved by the party
responsible for compliance
could void the user’s authority
to operate the equipment.

The jack, jack handle, and wheel lug
nut wrench are stored in the luggage
compartment. Pull up the luggage
box cover to reach this equipment.
(1) Jack handle
(2) Jack
(3) Wheel lug nut wrench
Jacking instructions The jack is provided for emergency
tire changing only.
To prevent the jack from “rattling”
while the vehicle is in motion, store it
properly.
Follow jacking instructions to reduce
the possibility of personal injury.
WARNING
- Changing tires
 Never attempt vehicle repairs in the traffic lanes of a public
road or highway.
 Always move the vehicle com- pletely off the road and onto
the shoulder before trying to
change a tire. The jack should
be used on level firm ground.
If you cannot find a firm, level
place off the road, call a tow-
ing service company for
assistance.
 Be sure to use the correct front and rear jacking posi-
tions on the vehicle; never
use the bumpers or any other
part of the vehicle for jack
support.
 The vehicle can easily roll off the jack causing serious
injury or death. No person
should place any portion of
their body under a vehicle that
is supported only by a jack;
use vehicle support stands.

7. Place the jack at the front or rearjacking position closest to the tire
you are changing. Place the jack
at the designated locations under
the frame. 8. Insert the jack handle into the jack
and turn it clockwise, raising the
vehicle until the tire just clears the
ground. This measurement is
approximately 1.2 in (30 mm).
Before removing the wheel lug
nuts, make sure the vehicle is sta-
ble and that there is no chance for
movement or slippage.
WARNING
- Jack location

69. 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. 10. 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 tapered 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 fin-
gers again.
11. 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 han-
dle. Go around the wheel tightening
every other nut until they are all tight.
Then double-check each nut for
tightness. After changing wheels,
have an authorized HYUNDAI dealer
tighten the wheel nuts to their proper
torque as soon as possible.
Wheel nut tightening torque:
Steel wheel & aluminum alloy wheel:
65~79 lb·ft (9~11 kg·m)
WARNING
Wheels may have sharp edges.
Handle them carefully to avoid
possible severe injury. Before
putting the wheel into place, be
sure that there is nothing on the
hub or wheel (such as mud, tar,
gravel, etc.) that prevents the
wheel from fitting solidly
against the hub.
(Continued)
(Continued)
If there is, remove it. If there is
not good contact on the mount-
ing surface 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.

What to do in an emergency
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 cor-
rect 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 pos-
sible.
After you have changed wheels,
always secure the flat tire in its place
and return the jack and tools to their
proper storage locations.To prevent the jack, jack handle,
wheel lug nut wrench and spare tire
from rattling while the vehicle is in
motion, store them properly.
CAUTION
Your vehicle has metric threads
on the wheel studs and nuts.Make certain during wheelremoval that the same nuts thatwere removed are reinstalled -or, if replaced, that nuts withmetric threads and the samechamfer configuration are used.Installation of a non-metricthread nut on a metric stud orvice-versa will not secure thewheel to the hub properly andwill damage the stud so that itmust be replaced.
Note that most lug nuts do nothave metric threads. Be sure touse extreme care in checkingfor thread style before installingaftermarket lug nuts or wheels.If in doubt, consult an author-ized HYUNDAI dealer.
WARNING
- Wheel studs
If the studs are damaged, they
may lose their ability to retain
the wheel. This could lead to the
loss of the wheel and a collision
resulting in serious injuries.
WARNING -
Inadequate
spare tire pressure
Check the inflation pressures as
soon as possible after installing
the spare tire. Adjust it to the
specified pressure, if necessary.
