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
0.47 in (12 mm). Damage to your vehicle
caused by improper snow chain use is
not covered by your vehicle manufactur-
ers warranty.
When using tire chains, install them on
the front tires only.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 yourtires. Incorrect snow chains can cause damage to the vehicle bodyand suspension and may not becovered by your vehicle manufac- turer warranty. Also, the snowchain connecting hooks may be damaged from contacting vehiclecomponents causing the snowchains to come loose from the tire. Make sure the snow chainsare SAE class “S” certified.
 Always check chain installation for proper mounting after drivingapproximately 0.3 to 0.6 miles (0.5 to 1 km) to ensure safe mounting.Retighten or remount the chainsif 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.

Driving your vehicle
Certification label
The certification label is located on
the driver's door sill at the center pil-
lar.
This label shows the maximum
allowable weight of the fully loaded
vehicle. This is called the GVWR
(Gross Vehicle Weight Rating). The
GVWR includes the weight of the
vehicle, all occupants, fuel and
cargo.
This label also tells you the maxi-
mum weight that can be supported
by the front and rear axles, called
Gross Axle Weight Rating (GAWR).To find out the actual loads on your
front and rear axles, you need to go
to a weigh station and weigh your
vehicle. Your dealer can help you with
this. Be sure to spread out your load
equally on both sides of the center-
line.
The label will help you decide how
much cargo and installed equipment
your vehicle can carry.
If you carry items inside your vehicle
- like suitcases, tools, packages, or
anything else - they are moving as
fast as the vehicle. If you have to stop
or turn quickly, or if there is a crash,
the items will keep going and can
cause an injury if they strike the driv-
er or a passenger.
OBH059070
WARNING -
Over loading
 Never exceed the GVWR for your vehicle, the GAWR for
either the front or rear axle
and vehicle capacity weight.
Exceeding these ratings can
cause an accident or vehicle
damage. You can calculate the
weight of your load by weigh-
ing the items (or people)
before putting them in the
vehicle. Be careful not to over-
load your vehicle.
(Continued)
(Continued)
 Do not load your vehicle anyheavier than the GVWR, either
the maximum front or rear
GAWR and vehicle capacity
weight. If you do, parts,
including tires on your vehicle
can break, and it can change
the way your vehicle handles
and braking ability. This could
cause you to lose control and
crash. Also, overloading can
shorten the life of your vehi-
cle.

WARNING
 Overloading your vehicle can
cause heat buildup in your
vehicle's tires and possible
tire failure that could lead to a
crash.
 Overloading your vehicle can cause increased stopping dis-
tances that could lead to a
crash.
 A crash resulting from poor handling, vehicle damage, tire
failure, or increased stopping
distances could result in seri-
ous injury or death.
WARNING
- Loose cargo
Items you carry inside your
vehicle can strike and injure
occupants in a sudden stop or
turn, or in a crash.
 Put items in the cargo area of your vehicle. Try to spread the
weight evenly.
 Never stack items, like suit- cases, inside the vehicle
above the tops of the seats.
 Do not leave an unsecured child restraint in your vehicle.
 When you carry something inside the vehicle, secure it.
 Do not drive with a seat folded down unless necessary.
CAUTION
 Overloading your vehicle may
cause damage. Repairs wouldnot be covered by your warran-ty. Do not overload your vehicle.
 Using heavier suspension com- ponents to get added durabilitymight not change your weightratings. Ask your dealer to helpyou load your vehicle the rightway.

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.

What to do in an emergency86✽
✽NOTICEIf the TPMS indicator does not illu-
minate for 3 seconds when the igni-
tion switch is turned to the ON posi-
tion or engine is running, or if they
remain illuminated after coming on
for approximately 3 seconds, 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 turn on and illuminate 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.

What to do in an emergency
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 orradios transmitter 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, mobilecharger, remote starter, navi-gation etc. are used in thevehicle. This can interfere withnormal operation of the TirePressure Monitoring System(TPMS).

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
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.
