Tires
Adjust the tire inflation pressures to
specification. Low tire inflation pressures
will result in overheating and possible
failure of the tires.
Avoid using worn or damaged tires which
may result in reduced traction or tire fail-
ure.
✽✽NOTICE
Never exceed the maximum tire inflation
pressure shown on the tires.
Fuel, engine coolant and engine oil
High speed travel consumes more fuel
than urban motoring. Do not forget to
check both engine coolant and engineoil.
Drive belt
A loose or damaged drive belt may result
in overheating of the engine.
WARNING
Underinflated or overinflated tires can cause poor handling,
loss of vehicle control, and sud-den tire failure leading to acci-
dents, injuries, and even death.
Always check tires for proper
inflation before driving. For prop-
er tire pressures, refer to “Tires
and wheels” in section 8.
Driving on tires with no or insuffi- cient tread is dangerous. Worn-out tires can result in loss of
vehicle control, collisions, injury,
and even death. Worn-out tiresshould be replaced as soon as
possible and should never be
used for driving. Always check
the tire tread before driving your
car. For further information and
tread limits, refer to “Tires and
wheels” in section 7.

More severe weather conditions of winter
result in greater wear and other prob-
lems. To minimize winter driving problem,
you should follow these suggestions: Snowy or icy conditions
To drive your vehicle in deep snow, it may
be necessary to use snow tires or to
install tire chains on your tires. If snow
tires are needed, it is necessary to select
tires equivalent in size and type of the
original equipment tires. Failure to do so
may adversely affect the safety and han-
dling of your car. Furthermore, speeding,
rapid acceleration, sudden brake appli-
cations, and sharp turns are potentially
very hazardous practices.
During deceleration, use engine braking
to the fullest extent. Sudden brake appli-
cations on snowy or icy roads may cause
skids to occur. You need to keep suffi-
cient distance between the vehicle in
operation in front and your vehicle. Also,
apply the brake gently. It should be notedthat installing tire chains on the tire will
provide a greater driving force, but will
not prevent side skids.
✽✽
NOTICE
Tire chains are not legal in all states.
Check state laws before fitting tire
chains.
Snow tires
If you mount snow tires on your vehicle,
make sure they are radial tires of the
same size and load range as the original
tires. Mount snow tires on all four wheels
to balance your vehicle’s handling in all
weather conditions. Keep in mind that the
traction provided by snow tires on dry
roads may not be as high as your vehi-
cle's original equipment tires. You should
drive cautiously even when the roads are
clear. Check with the tire dealer for max-
imum speed recommendations.
Do not install studded tires without first checking local, state and municipal regu- lations for possible restrictions againsttheir use.
WINTER DRIVING
WARNING - Snow tire size
Snow tires should be equivalent in
size and type to the vehicle's stan-
dard tires. Otherwise, the safety
and handling of your vehicle may
be adversely affected.

Driving your vehicle
Tire chains
Since the sidewalls of radial tires are
thinner, they can be damaged by mount-
ing some types of snow chains on them.
Therefore, the use of snow tires is rec-
ommended instead of snow chains. Do
not mount tire chains on vehicles
equipped with aluminum wheels; snow
chains may cause damage to the wheels.
If snow chains must be used, use wire-
type chains with a thickness of less than
12 mm (0.47 in). Damage to your vehicle
caused by improper snow chain use is
not covered by your vehicle manufactur-
ers warranty.
Install tire chains only on the rear tires.Chain installation
When installing chains, follow the manu-
facturer's instructions and mount them as
tightly as you can. Drive slowly with
chains installed. If you hear the chains
contacting the body or chassis, stop and
tighten them. If they still make contact,
slow down until it stops. Remove the
chains as soon as you begin driving on
cleared roads.
CAUTION
Make sure the snow chains are
the correct size and type for your
tires. Incorrect snow chains cancause damage to the vehicle bodyand suspension and may not be covered by your vehicle manufac-
turer warranty. Also, the snowchain connecting hooks may bedamaged from contacting vehicle
components causing the snow chains to come loose from thetire. Make sure the snow chainsare SAE class “S” certified.
Always check chain installation for proper mounting after drivingapproximately 0.5 to 1 km (0.3 to0.6 miles) to ensure safe mount-ing. Retighten or remount the
chains if they are loose.
WARNING
- Mounting chains
When mounting snow chains, park
the vehicle on level ground away
from traffic. Turn on the vehicle
Hazard Warning flashers and place
a triangular emergency warning
device behind the vehicle if avail-
able. Always place the vehicle in P
(Park), apply the parking brake and
turn off the engine before installing
snow chains.OVI059051

What to do in an emergency
TIRE PRESSURE MONITORING SYSTEM (TPMS) (IF EQUIPPED)
(1) Low Tire Pressure Telltale
(2) TPMS Malfunction Indicator
(3) Low Tire Pressure Position
Telltale (if equipped) 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 under-inflated 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 oper-
ating properly. The TPMS malfunction
indicator is provided by a separate
telltale, which displays the symbol
"TPMS" when illuminated. When themalfunction indicator is illuminated,
the system may not be able to detect
or signal low tire pressure as intend-
ed. TPMS malfunctions may occur for
a variety of reasons, including theinstallation of replacement or alter-
nate tires or wheels on the vehicle
that prevent the TPMS from function-
ing properly.

Always check the TPMS malfunction telltale 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 properly.
✽✽
NOTICE
If the TPMS, Low Tire Pressure tell-
tale do not illuminate for 3 seconds
when the ignition switch is turned to
the ON position or engine is run-
ning, or if they remain illuminated
after coming on for approximately 3
seconds, take your car to your near-
est authorized HYUNDAI dealer
and have the system checked.
Low tire pressure tell- tale
Low tire pressure posi- tion telltale
When the tire pressure monitoring
system warning indicators are illumi-
nated, one or more of your tires is
significantly under-inflated. The lowtire pressure position telltale (supple-mental) will indicate which tire is sig-
nificantly under-inflated by illuminat-ing the corresponding position on theLCD screen (if equipped).
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 and Position
telltale will remain on until you have
the low pressure tire repaired and
replaced on the vehicle.
✽✽
NOTICE
The spare tire is not equipped with a
tire pressure sensor.
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 area or from a cold area to a warmarea, or the outside temperatureis greatly higher or lower, you should check the tire inflationpressure and adjust the tires tothe recommended tire inflation pressure.

What to do in an emergency
TPMS (Tire Pressure Monitoring System)malfunction indicator
The TPMS malfunction indicator
comes on and stays on when there is
a problem with the Tire Pressure
Monitoring System. The system is
able to correctly detect an under-
inflation warning at the same time as
system failure then it will illuminate
both the TPMS malfunction and the
low tire pressure telltale. If the Front
Left sensor fails, the TPMS malfunc-
tion indicator illuminates, but if the
Front Right, Rear Left, or Rear Right
tire is under-inflated, the low tire
pressure and position telltales may
illuminate together with 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 brakingdistances.
Continued driving on low pres- sure tires can cause the tires to
overheat and fail.TPMSCAUTION
The TPMS malfunction indica- tor may be illuminated if thevehicle is moving around elec-tric power supply cables orradios transmitter such as at police stations, governmentand public offices, broadcast-ing stations, military installa-tions, airports, or transmitting towers, etc. This can interferewith normal operation of theTire Pressure Monitoring System (TPMS).
The TPMS malfunction indica- tor may be illuminated if someelectronic devices, such asnotebook computers, are usedin the vehicle. This can inter- fere with normal operation ofthe Tire Pressure MonitoringSystem (TPMS).
If there is a failed tire sensor, it is possible for TPMS to tem-porarily learn a replacementsensor when you drive closely to another vehicle equippedwith TPMS too. In rare cases,this may temporarily delay the TPMS malfunction turning on.

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. 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 as soon as possi-
ble. The spare tire is not equipped with a
tire pressure monitoring sensor.
When the low pressure tire is
replaced with the spare tire, the low
tire pressure and the low tire pres-
sure position telltales may extinguish
and the TPMS malfunction indicator
may illuminate after restarting and
within 20 minutes continuous driving.
The TPMS malfunction indicator may
remain on until the original tire
equipped with a tire monitoring sen-sor is reinflated to the recommended
pressure and reinstalled on the vehi-
cle then driving for a few minutes.
Once the low pressure tire is re- inflated to the recommended pres-
sure and installed on the vehicle, theTPMS malfunction indicator and the
low tire pressure and position tell-
tales will extinguish within a few min-
utes of driving.
If the indicators are not extinguished
after a few minutes, please visit an
authorized HYUNDAI dealer.
You may not be able identify a low
tire by simply looking at it. Alwaysuse a good quality tire pressuregauge to measure the tire's inflation
pressure. Please note that a tire that
is hot (from being driven) will have ahigher pressure measurement than atire that is cold (from sitting station-
ary for at least 3 hours and driven
less than 1.6km (1 mile) during 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.
A cold tire means the vehicle has
been sitting for 3 hours and driven forless than 1.6km (1 mile) in that 3
hour period.
CAUTION
NEVER use a puncture-repair-
ing agent to repair and/or inflatea low pressure tire. The tire sealant can damage the tirepressure sensor. If used, youwill have to replace the tire pres- sure sensor.

611
What to do in an emergency
CAUTION
Do not use any tire sealant ifyour vehicle is equipped witha Tire Pressure MonitoringSystem. The liquid sealant candamage the tire pressure sen- sors.
In order to correctly monitor the tires with inflation, the 4tire pressure monitoring sen-sors should be exactly fitted to each of the 4 driven wheel.There should be no other sen-sors in the vehicle include spare tire, it may cause thesystem couldn’t monitor thetires with inflation correctly.
WARNING - Protecting
TPMS
Tampering with, modifying, or
disabling the Tire PressureMonitoring System (TPMS)
components may interfere withthe system's ability to warn the
driver of low tire pressure con-
ditions and/or TPMS malfunc-
tions. Tampering with, modify-
ing, or disabling the TirePressure Monitoring System
(TPMS) components 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 roaddebris.
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.
