IF THE ENGINE OVERHEATS
If your temperature gauge indicates over-
heating, you experience a loss of power,
or hear loud pinging or knocking, the
engine is probably too hot. If this hap-
pens, you should:
1. Pull off the road and stop as soon as itis safe to do so.
2. Place the shift lever in P (automatic transaxle) and set the parking brake. If
the air conditioning is on, turn it off.
3. If engine coolant is running out under the car or steam is coming out from
the hood, stop the engine. Do not open
the hood until the coolant has stopped
running or the steaming has stopped.
If there is no visible loss of engine
coolant and no steam, leave the
engine running and check to be sure
the engine cooling fan is operating. If
the fan is not running, turn the engine
off. 4. Check to see if the water pump drive
belt is missing. If it is not missing,
check to see that it is tight. If the drive
belt seems to be satisfactory, check for
coolant leaking from the radiator,
hoses or under the car. (If the air con-
ditioning had been in use, it is normal
for cold water to be draining from it
when you stop.)
5. If the water pump drive belt is broken or engine coolant is leaking out, stop
the engine immediately and call the
nearest authorized HYUNDAI dealer
for assistance. 6. If you cannot find the cause of the
overheating, wait until the engine tem-
perature has returned to normal. Then,
if coolant has been lost, carefully add
coolant to the reservoir to bring the
fluid level in the reservoir up to the
halfway mark.
7. Proceed with caution, keeping alert for further signs of overheating. If over-
heating happens again, call an author-
ized HYUNDAI dealer for assistance.
WARNING
While the engine is running, keep
hair, hands and clothing away from
moving parts such as the fan and
drive belts to prevent injury.
CAUTION
Serious loss of coolant indicates
there is a leak in the cooling systemand this should be checked as soonas possible by an authorizedHYUNDAI dealer.
WARNING
Do not remove the radiator cap
when the engine is hot. This may
result in coolant being blown out of
the opening and cause serious
burns.

What to do in an emergency
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.

NOTICE
If the TPMS indicator does not illu-
minate for 3 seconds when the
engine start/stop button is pressed 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, use the inflator in the
Tire Mobility Kit located in the trunk.
If the tire cannot hold the newly
added air, or will not hold air after the
sealant is added, repair the tire.
The Low Tire Pressure telltale may
flash for approximately one minute
and then remain continuously illumi-
nated 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).

Changing a tire with TPMS
If you have a flat tire, the Low Tire
Pressure telltale will come on.
A spare tire may be used if one is
available.
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 a 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 flat tire with a
compact spare tire, the Low Tire
Pressure Telltale may blink or illumi-
nate because the compact spare tire
does not have a TPMS sensor.
Once the flat tire is replace, inflated
to the recommended pressure and
installed on the vehicle, the TPMS
malfunction indicator and the low tire
pressure telltale will extinguish 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 a new wheel andtire, the TPMS sensor on thereplacement wheel should be ini-tiated and the TPMS sensor onthe original mounted wheelshould be deactivated. If theTPMS sensor on the originalmounted is kept in the vehiclewhile active, the tire pressuremonitoring system may not oper-ate properly. Have the tire withTPMS serviced or replaced by anauthorized HYUNDAI dealer.
CAUTION
Never use a puncture-repairingsealant not approved byHYUNDAI to repair and/or inflatea flat tire. A tire sealant notapproved by HYUNDAI maydamage the tire pressure sen-sor. The sealant on the tire pres-sure sensor and wheel shouldbe cleaned when you replace thetire with a new one.
WARNING
If you do not use the authorized
tires or wheels, the TPMS may
malfunction.

613
What to do in an emergency
You may not be able to 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.
CAUTION
Changes or modifications not
expressly approved by the partyresponsible for compliance couldvoid the user’s authority to operate the equipment.
