If your engine coolant temperature
gauge indicates overheating, you
experience a loss of power, or hear
loud pinging or knocking, the engine
may be overheating. If this happens,
you should:
1. Turn ON the hazard warning flash-er, pull off the road and stop as
soon as it is safe to do so.
2. Place the shift lever in P (Park) and set the parking brake.
3. Make sure that there is no hotsteam gushing out of the engine
compartment. When it is safe to
do so, open the engine compart-
ment, and check the water-pump
connector. When the water-pumpconnector is disconnected, stop
the engine, re-connect the water-
pump connector, and then re-start
the engine.
4. Set the temperature and the air flow to the maximum, and turn ON
the air conditioner. 5. When the Service warning light
( ) illuminates on the instru-
ment cluster, immediately stop the
engine, and contact an authorized
HYUNDAI dealer. When the
engine warning light ( ) illumi-
nates, or when the coolant or hotsteams gush out of the engine
compartment, leave the engine
compartment opened, while run-
ning the engine. This is to ventilate
the engine compartment and to
cool down the engine.
6. Check the coolant temperature gauge on the instrument cluster to
make sure the coolant temperature
is sufficiently cooled down. Check
the coolant level. When it is insuffi-
cient, check its connection with the
radiator, the heater hose, and the
water pump for any leakage. When
there is no leakage, add the
coolant. However, if the problems
persists, such as the illumination of
the warning lights, leakages, or the
cooling-fan malfunction, which may
overheat the engine, immediately
stop the engine, and have your
vehicle checked by an authorized
HYUNDAI dealer.

What to do in an emergency
7. If you cannot find the cause of theoverheating, wait until the engine
temperature has returned to nor-
mal. Then, if coolant has beenlost, carefully add coolant to the
reservoir to bring the fluid level in
the reservoir up to the halfway
mark.
8. Proceed with caution, keeping alert for further signs of overheat-
ing. If overheating happens again,
call an authorized HYUNDAI deal-
er for assistance.
Serious loss of coolant indi-cates a leak in the cooling sys-
tem and should be checked as
soon as possible by an author-
ized HYUNDAI dealer.
CAUTION
The electric motor for
the cooling fan may
continue to operate
or start up when theengine is not running
and can cause serious injury.
Keep hands, clothing and tools
away from the rotating fan
blades of the cooling fan.
WARNING
Your vehicle is equipped with a pres-
surized coolant
reserve tank. NEVER
remove the coolant
reserve tank cap or the radiatordrain plug while the engine and
radiator are HOT. Hot coolant
and steam may blow out under
pressure, causing serious
injury.
Turn the engine off and wait
until the engine cools down.
Use extreme care when remov-
ing the coolant reserve tank
cap. Wrap a towel or thick rag
around it, and turn it counter-
clockwise slowly to release
some of the pressure from the
system. Step back while thepressure is released.
When you are sure all the pres-
sure has been released, contin-ue turning the cap counter-
clockwise to remove it.

Tire Pressure Monitoring System
Each tire, including the spare (if pro-
vided), should be checked monthlywhen 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 yourtires 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 underinflated tire causes the
tire to overheat and can lead to tire
failure. Under-inflation also reduces fuel effi-
ciency 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 toindicate when the system is not
operating properly.
The TPMS malfunction indicator is
combined with the low tire pressure
telltale. When the system detects a
malfunction, the telltale will flash for
approximately one minute and then
remain continuously illuminated. This
sequence will continue upon subse-
quent vehicle start-ups as long as
the malfunction exists. When the malfunction indicator is
illuminated, the system may not be
able to detect or signal low tire pres-
sure as intended. TPMS malfunc-
tions may occur for a variety of rea-
sons, including the installation of
replacement or alternate tires or
wheels on the vehicle that prevent
the TPMS from functioning properly.
Always check the TPMS malfunctiontelltale after replacing one or more
tires or wheels on your vehicle toensure that the replacement or alter-
nate tires and wheels allow the
TPMS to continue to function proper-
ly.
What to do in an emergency
Over-inflation or under-inflation
can reduce tire life, adversely
affect vehicle handling, and
lead to sudden tire failure that
may cause loss of vehicle con-
trol resulting in an accident.
WARNING

6-11
What to do in an emergency
If any of the below happens, have
the system checked by an author-
ized HYUNDAI dealer.
1. The Low Tire Pressure Telltale/TPMS Malfunction Indicator
does not illuminate for 3 sec-
onds when the ignition switchis placed to the ON position orengine is running.
2. The TPMS Malfunction Indicator remains illuminated after blink-
ing for approximately 1 minute.
3. The Low Tire Pressure Position Telltale remains illuminated.

Position and Tire
Pressure Telltale
When the tire pressure monitoring
system warning indicators are illumi-
nated and warning message dis-
played on the cluster LCD display,
one or more of your tires is signifi-
cantly under-inflated. The Low Tire
Pressure Position Telltale will indi-cate which tire is significantly under-
inflated by illuminating the corre-sponding position light.
If either telltale illuminates, immedi-
ately reduce your speed, avoid hard
cornering and anticipate increased
stopping distances. You should stop
and check your tires as soon as pos-
sible. Inflate the tires to the proper
pressure as indicated on the vehi-cle's placard or tire inflation pressure
label located on the driver's side cen-ter pillar 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.
The Low Tire Pressure Telltale will
remain on and the TPMS Malfunction
Indicator may blink for one minuteand then remain illuminated (when
the vehicle is driven approximately
20 minutes at speed above 25 km/h
(15.5 mph)) until you have the lowpressure tire repaired and replaced
on the vehicle.
Information
The spare tire is not equipped with a
tire pressure sensor.

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.
Have the system checked by an
authorized HYUNDAI dealer as soon
as possible. If there is a malfunction with the
TPMS, the Low Tire Pressure
Position Telltale will not be dis-
played even though the vehicle
has an under-inflated tire.
NOTICE
What to do in an emergency
In winter or cold weather, the
Low Tire Pressure Telltale maybe illuminated if the tire pres-sure was adjusted to the recom-mended tire inflation pressure
in warm weather. It does not
mean your TPMS is malfunc-tioning because the decreased
temperature leads to a propor-
tional lowering of tire pressure.
When you drive your vehicle
from a warm area to a cold area
or from a cold area to a warm
area, or the outside temperature
is greatly higher or lower, you
should check the tire inflationpressure and adjust the tires tothe recommended tire inflation
pressure.
CAUTION
Low pressure damage
Significantly low tire pressure
makes the vehicle unstable and
can contribute to loss of vehicle
control and increased brakingdistances.
Continued driving on low pres- sure tires can cause the tires to
overheat and fail.
WARNING

6-13
What to do in an emergency
The TPMS Malfunction Indicator
may illuminate after blinking for
one minute if the vehicle is near
electric power supply cables or
radio transmitters such as police
stations, government and public
offices, broadcasting stations,
military installations, airports,
transmitting towers, etc.
Additionally, the TPMS Malfunction
Indicator may illuminate if snow
chains are used or electronic
devices such as computers, charg-
ers, remote starters, navigation,
etc. This may interfere with normal
operation of the TPMS.
Changing a Tire with TPMS
If you have a flat tire, the Low Tire
Pressure and Position telltales will
come on. Have the flat tire repaired
by an authorized HYUNDAI dealer
as soon as possible or replace the
flat tire with the spare tire. The spare tire (if equipped) does not
come with a tire pressure monitoring
sensor. When the low pressure tire orthe flat tire is replaced with the spare
tire, the Low Tire Pressure Telltale
will remain on. Also, the TPMSMalfunction Indicator will illuminate
after blinking for one minute if the
vehicle is driven at speed above 25
km/h (15.5 mph) for approximately
20 minutes.Once the original tire equipped with
a tire pressure monitoring sensor isreinflated to the recommended pres-
sure and reinstalled on the vehicle,
the Low Tire Pressure Telltale andTPMS Malfunction Indicator will go
off within a few minutes of driving.
If the indicators do not extinguish
after a few minutes, please visit an
authorized HYUNDAI dealer. Each wheel is equipped with a tire pressure sensor mounted inside the
tire behind the valve stem (except for
the spare tire). You must use TPMS
specific wheels. It is recommended
that you always have your tires serv-
iced by an authorized HYUNDAI
dealer.
You may not be able to identify a tire
with low pressure by simply looking
at it. Always use a good quality tire
pressure gauge to measure. Pleasenote that a tire that is hot (from being
driven) will have a higher pressuremeasurement than a tire that is cold.
NOTICE
6
It is recommended that you do not use a puncture-repairing
agent not approved by
HYUNDAI dealer to repair
and/or inflate a low pressure
tire. Tire sealant not approved
by HYUNDAI dealer may dam-
age the tire pressure sensor.
CAUTION

6-14
A cold tire means the vehicle has
been sitting for 3 hours and driven forless than 1.6 km (1 mile) 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.
