What to do in an emergency10
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.

the possibility of personal injury.
WARNING
- Changing tires
 Never attempt vehicle repairs in the traffic lanes of a public
road or highway.
 Always move the vehicle com- pletely off the road and onto
the shoulder before trying to
change a tire. The jack should
be used on level firm ground.
If you cannot find a firm, level
place off the road, call a tow-
ing service company for
assistance.
 Be sure to use the correct front and rear jacking posi-
tions on the vehicle; never
use the bumpers or any other
part of the vehicle for jack
support.
 The vehicle can easily roll off the jack causing serious
injury or death. No person
should place any portion of
their body under a vehicle that
is supported only by a jack;

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

What to do in an emergency
 Do not take this vehicle through anautomatic car wash while the com-
pact spare tire is installed.
 Do not use tire chains on the com- pact spare tire. Because of the
smaller size, a tire chain will not fit
properly. This could damage the
vehicle and result in loss of the
chain.
 Do not use the compact spare tire on any other vehicle because this
tire has been designed especially
for your vehicle.
 The compact spare tire’s tread life is shorter than a regular tire.
Inspect your compact spare tire
regularly and replace worn com-
pact spare tires with the same size
and design, mounted on the same
wheel.  The compact spare tire should not
be used on any other wheels, nor
should standard tires, snow tires,
wheel covers or trim rings be used
with the compact spare wheel. If
such use is attempted, damage to
these items or other car compo-
nents may occur.
 Do not use more than one compact spare tire at a time.
 Do not tow a trailer while the com- pact spare tire is installed.

Maintenance
The following lists are vehicle checks and
inspections that should be performed by
the owner or an authorized HYUNDAI
dealer at the frequencies indicated to
help ensure safe, dependable operation
of your vehicle.
Any adverse conditions should be
brought to the attention of your dealer as
soon as possible.
These Owner Maintenance Checks are
generally not covered by warranties and
you may be charged for labor, parts and
lubricants used.
Owner maintenance schedule When you stop for fuel: Check the engine oil level.
 Check coolant level in coolant reser-voir.

WARNING
- Maintenance work
 Performing maintenance work on
a vehicle can be dangerous. You
can be seriously injured while
performing some maintenance
procedures. If you lack sufficient
knowledge and experience or the
proper tools and equipment to do
the work, have it done by an
authorized HYUNDAI dealer.
 Working under the hood with the engine running is dangerous. It
becomes even more dangerous
when you wear jewelry or loose
clothing. These can become
entangled in moving parts and
result in injury. Therefore, if you
must run the engine while work-
ing under the hood, make certain
that you remove all jewelry (espe-
cially rings, bracelets, watches,
and necklaces) and all neckties,
scarves, and similar loose cloth-
ing before getting near the
engine or cooling fans.
OWNER MAINTENANCE
WARNING
Be careful when checking your
engine coolant level when the
engine is hot. Scalding hot coolant
and steam may blow out under
pressure. This could cause burns
or other serious injury.

Maintenance67While operating your vehicle: Note any changes in the sound of theexhaust or any smell of exhaust fumes
in the vehicle.
 Check for vibrations in the steering wheel. Notice any increased steering
effort or looseness in the steering
wheel, or change in its straight-ahead
position.
 Notice if your vehicle constantly turns slightly or “pulls” to one side when trav-
eling on smooth, level road.
 When stopping, listen and check for unusual sounds, pulling to one side,
increased brake pedal travel or “hard-
to-push” brake pedal.
 If any slipping or changes in the oper- ation of your transaxle occurs, check
the transaxle fluid level.
 Check automatic transaxle P (Park) function.
 Check parking brake.
 Check for fluid leaks under your vehicle (water dripping from the air condition-
ing system during or after use is nor-
mal).
