TIRE PRESSURE MONITORING SYSTEM (TPMS)
(1) Low tire pressure telltale /
TPMS malfunction indicator
Each tire, including the spare (if pro-
vided), should be checked monthly
when cold and inflated to the inflation
pressure recommended by the vehi-
cle manufacturer on the vehicle plac-
ard or tire inflation pressure label. (If
your vehicle has tires of a different
size than the size indicated on the
vehicle placard or tire inflation pres-
sure label, you should determine the
proper tire inflation pressure for
those tires.) As an added safety feature, your
vehicle has been equipped with a tire
pressure monitoring system (TPMS)
that illuminates a low tire pressure
telltale when one or more of your
tires is significantly under-inflated.
Accordingly, when the low tire pres-
sure telltale illuminates, you should
stop and check your tires as soon as
possible, and inflate them to the
proper pressure. Driving on a signifi-
cantly under-inflated tire causes the
tire to overheat and can lead to tire
failure. Under-inflation also reduces
fuel efficiency and tire tread life, and
may affect the vehicle’s handling and
stopping ability.
Please note that the TPMS is not a
substitute for proper tire mainte-
nance, and it is the driver’s responsi-
bility to maintain correct tire pres-
sure, even if under-inflation has not
reached the level to trigger illumina-
tion of the TPMS low tire pressure
telltale.
Your vehicle has also been equipped
with a TPMS malfunction indicator to
indicate when the system is not
operating properly. The TPMS mal-
function indicator is combined with
the low tire pressure telltale. When
the system detects a malfunction,
the telltale will flash for approximate-
ly one minute and then remain con-
tinuously illuminated. This sequence
will continue upon subsequent vehi-
cle start-ups as long as the malfunc-
tion exists. When the malfunction
indicator is illuminated, the system
may not be able to detect or signal
low tire pressure as intended. TPMS
malfunctions may occur for a variety
of reasons, including the installation
of replacement or alternate tires or
wheels on the vehicle that prevent
the TPMS from functioning properly.
Always check the TPMS malfunction
telltale after replacing one or more
tires or wheels on your vehicle to
ensure that the replacement or alter-
nate tires and wheels allow the
TPMS to continue to function proper-
ly.

What to do in an emergency
✽
✽NOTICE
If the TPMS indicator does not illu-
minate for 3 seconds when the
engine start/stop button is turned to
the ON position or engine is run-
ning, or If it comes on after blinking
for approximately one minute, take
your car to your nearest authorized
HYUNDAI dealer and have the sys-
tem checked.
Low tire pressure tell-
tale
When the tire pressure monitoring
system warning indicator is illuminat-
ed, one or more of your tires is sig-
nificantly under-inflated.
If the telltale illuminates, immediately
reduce your speed, avoid hard cor-
nering and anticipate increased stop-
ping distances. You should stop and
check your tires as soon as possible.
Inflate the tires to the proper pres-
sure as indicated on the vehicle’s
placard or tire inflation pressure label
located on the driver’s side center pil-
lar outer panel. If you cannot reach a
service station or if the tire cannot
hold the newly added air, replace the
low pressure tire with the spare tire.
Then the Low Tire Pressure telltale
may flash for approximately one
minute and then remain continuously
illuminated after restarting and about
20 minutes of continuous driving
before you have the low pressure tire
repaired and replaced on the vehicle.CAUTION
In winter or cold weather, the low tire pressure telltale may beilluminated if the tire pressurewas adjusted to the recom-mended tire inflation pressurein warm weather. It does notmean your TPMS is malfunction-ing because the decreased tem-perature leads to a proportionallowering of tire pressure.
When you drive your vehiclefrom a warm area to a cold areaor from a cold area to a warmarea, or the outside temperatureis greatly higher or lower, youshould check the tire inflationpressure and adjust the tires tothe recommended tire inflationpressure.

TPMS (Tire Pressure
Monitoring System)
malfunction indicator
The TPMS malfunction indicator will
illuminate after it blinks for approxi-
mately one minute when there is a
problem with the Tire Pressure
Monitoring System. If the system is
able to correctly detect an under infla-
tion warning at the same time as sys-
tem failure then it will illuminate the
TPMS malfunction indicator.
Have the system checked by an
authorized HYUNDAI dealer as soon
as possible to determine the cause
of the problem.
WARNING - Low pressure damage
Significantly low tire pressure
makes the vehicle unstable and
can contribute to loss of vehicle
control and increased braking
distances.
Continued driving on low pres-
sure tires can cause the tires to
overheat and fail.CAUTION
The TPMS malfunction indica- tor may be illuminated if thevehicle is moving around elec-tric power supply cables orradio transmitters such as atpolice stations, governmentand public offices, broadcast-ing stations, military installa-tions, airports, or transmittingtowers, etc. This can interferewith normal operation of theTire Pressure MonitoringSystem (TPMS).
The TPMS malfunction indica- tor may illuminate if snowchains or some separatelypurchased devices such asnotebook computers, mobilechargers, remote starters,GPS navigation etc. are usedin the vehicle. This can inter-fere with normal operation ofthe Tire Pressure MonitoringSystem (TPMS).

What to do in an emergency
Changing a tire with TPMS
If you have a flat tire, the Low Tire
Pressure telltale 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 compact spare tire, the
Low Tire Pressure Telltale will blink or
remain on until the low pressure tire
is repaired and placed on the vehicle.
After you replace the low pressure tire
with the compact spare tire, the Low
Tire Pressure Telltale may blink or illu-
minate because the compact spare
tire does not have a TPMS sensor.
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-repairingagent not approved by HYUNDAIto repair and/or inflate a lowpressure tire. The tire sealantnot approved by HYUNDAI maydamage the tire pressure sen-sor. The sealant on the tire pres-sure sensor and wheel shall beeliminated when you replace thetire with a new one.
WARNING
If you do not use the authorized
tires or wheels, the malfunction
of TPMS may occur.

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 sealantexcept the Tire Mobility Kitapproved by HYUNDAI if yourvehicle is equipped with a TirePressure Monitoring System.The liquid sealant can damagethe tire pressure sensors.
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.

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.
Refer to “Tires and wheels” sec-
tion 8.

What to do in an emergency
Important - use of compact spare tire
Your vehicle is equipped with a com-
pact spare tire. This compact spare
tire takes up less space than a regu-
lar-size tire. This tire is smaller than a
conventional tire and is designed for
temporary use only.The compact spare should be inflat-
ed to 60 psi (420 kPa).
✽ ✽NOTICE
Check the inflation pressure after
installing the spare tire. Adjust it to
the specified pressure, as necessary.
When using a compact spare tire,
observe the following precautions:
Under no circumstances should
you exceed 50 mph (80 km/h); a
higher speed could damage the
tire.
Ensure that you drive slowly enough for the road conditions to
avoid all hazards. Any road hazard,
such as a pothole or debris, could
seriously damage the compact
spare.
Any continuous road use of this tire could result in tire failure, loss of
vehicle control, and possible per-
sonal injury.
Do not exceed the vehicle’s maxi- mum load rating or the load-carry-
ing capacity shown on the sidewall
of the compact spare tire.
Avoid driving over obstacles. The compact spare tire diameter is
smaller than the diameter of a con-
ventional tire and reduces the
ground clearance approximately 1
inch (25 mm), which could result in
damage to the vehicle.
WARNING
The compact spare tire is for
emergency use only. Do not
operate your vehicle on this
compact spare at speeds over
50 mph (80 km/h). The original
tire should be repaired or
replaced as soon as is possible
to avoid failure of the spare
possibly leading to personal
injury or death.
CAUTION
You should drive carefully when the compact spare is inuse. The compact spareshould be replaced by theproper conventional tire andrim at the first opportunity.
The operation of this vehicle is not recommended withmore than one compact sparetire in use at the same time.

What to do in an emergency
IF YOU HAVE A FLAT TIRE (WITH TIREMOBILITYKIT, IF EQUIPPED)
Please read the instructions before
using the TireMobilityKit.
(1) TireMobilityKit bag
(2) Compressor
(3) Sealant bottleIntroduction
With the TireMobilityKit you stay mobile
even after experiencing a tire puncture.
The system of compressor and seal-
ing compound effectively and com-
fortably seals most punctures in a
passenger car tire caused by nails or
similar objects and reinflates the tire.
After you ensured that the tire is
properly sealed you can drive cau-
tiously on the tire (up to 200 km (120
miles)) at a max. speed of 80 km/h
(50 mph) in order to reach a vehicle or
tire dealer to have the tire replaced.
It is possible that some tires, especially
with larger punctures or damage to the
sidewall, cannot be sealed completely.Air pressure loss in the tire may
adversely affect tire performance.
For this reason, you should avoid
abrupt steering or other driving
maneuvers, especially if the vehicle is
heavily loaded or if a trailer is in use.
The TireMobilityKit is not designed or
intended as a permanent tire repair
method and is to be used for one tire
only.
This instruction shows you step by
step how to temporarily seal the
puncture simply and reliably.
Read the section "Notes on the safe
use of the TireMobilityKit".
OEL069019
WARNING
Do not use the TireMobilityKit if
a tire is severely damaged by
driving run flat or with insuffi-
cient air pressure.
Only punctured areas located
within the tread region of the
tire can be sealed using the
TireMobilityKit.
Damage to the sidewall must
not be repaired due to safety
reasons.
