7. Plug the compressor power cord(3) into the vehicle power outlet.
8. With the ignition switch in the ON position, switch on the compres-
sor and let it run for approximately
5~7 minutes to fill the sealant up
to proper pressure. (refer to the
Tire and Wheels, chapter 8). The
inflation pressure of the tire after
filling is unimportant and will be
checked/corrected later.
Be careful not to overinflate the
tire and stay away from the tire
when filling it. 9. Switch off the compressor.
10. Detach the hoses from the
sealant bottle connector and
from the tire valve.
Return the Tire Mobility Kit to its stor-
age location in the vehicle.
Distributing the sealant
11. Immediately drive approximately 4~6miles (7~10km or about 10
minutes) to evenly distribute the
sealant in the tire.
Do not exceed a speed of 50 mph
(80 km/h). If possible, do not fall
below a speed of 12 mph (20 km/h).
While driving, if you experience any
unusual vibration, ride disturbance or
noise, reduce your speed and drive
with caution until you can safely pull
off of the side of the road.
What to do in an emergency
Never 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 deal-
er may damage the tire pressure
sensor.
CAUTION
Do not attempt to drive your
vehicle if the tire pressure is
below 29 psi (200kpa). This
could result in an accident due
to sudden tire failure.
CAUTION
Do not leave your vehicle run-
ning in a poorly ventilated area
for extended periods of time.
Carbon monoxide poisoning
and suffocation can occur.

What to do in an emergency
Checking the tire inflation pres-
sure
1. After driving approximately 4~6miles (7~10km or about
10 minutes), stop at a safe loca-
tion.
2. Connect hose (9) of the compres- sor directly to the tire valve.
3. Plug the compressor power cord into the vehicle power outlet. 4. Adjust the tire inflation pressure to
the recommended tire inflation.
With the ignition switched on, pro- ceed as follows.
- To increase the inflation pres- sure:
Switch on the compressor, posi-
tion to [I]. To check the current
inflation pressure setting, briefly
switch off the compressor.
- To reduce the inflation pres- sure:
Loosen the screw cap (8) on the
compressor hose.
Information
The pressure gauge may show higher
than actual reading when the com-
pressor is running. To get an accurate
tire pressure, the compressor needs to
be turned off.

When you use the Tire Mobility
Kit including sealant not
approved by HYUNDAI, the tire
pressure sensors may be dam-
aged by sealant. The sealant on
the tire pressure sensor and
wheel should be removed when
you replace the tire with a new
one and inspect the tire pres-
sure sensors at an authorized
dealer.
CAUTION

6-24
In case of swallowing the sealant,rinse the mouth and drink plenty of
water. However, never give any-
thing to an unconscious person
and seek medical attention imme-
diately.
Long time exposure to the sealant may cause damage to bodily tissue
such as kidney, etc.

4. Unscrew the valve cap from thevalve of the defective wheel and
screw the filling hose (3) of the
sealant bottle onto the valve. 5. Plug the compressor power cord
(3) into the vehicle power outlet.
Only use the front passenger side
power outlet when connecting the
power cord.
6. With the Engine Start/Stop button in the ON position, switch on the
compressor and let it run for
approximately 5~7 minutes to fill
the sealant up to proper pressure.
(refer to the Tire and Wheels, chap-
ter 8). The inflation pressure of the
tire after filling is unimportant and
will be checked/corrected later.
Be careful not to overinflate the
tire and stay away from the tire
when filling it.
NOTICE

Securely install the sealant fill-
ing hose to the valve. If not,
sealant may flow backward,
possibly clogging the filling
hose.
CAUTION

Tire pressure
Do not attempt to drive your
vehicle if the tire pressure is
below 200 kPa (29 psi). This
could result in an accident due
to sudden tire failure.
CAUTION

Checking the tire inflation pres-sure
1. After driving approximately 4~6
miles (7~10 km or about 10 min),
stop at a safety location.
2. Connect the filling hose (3) of the compressor directly to the tire valve. 3. Plug the compressor power cord
into the vehicle power outlet.
4. Adjust the tire inflation pressure to the recomended tire inflation.
With the ignition swithched on, proceed as follows.
- To increase the inflation pres- sure : Switch on the compres-
sor. To check the current inflation
pressure setting, briefly switch
off the compressor.
- To reduce the inflation pres- sure: Press the button (9) on the
compressor.
Do not let the compressor run for
more than 10 minutes, otherwise
the device will overheat and may
be damaged.
Information
The pressure gauge may show higher
than actual reading when the com-
pressor is running. To get an accurate
tire reading, the compressor needs to
be turned off.

NOTICE
What to do in an emergency
OIGH067043
OLFH067037
The tire inflation pressure must
be at least 220 kPa (32 psi). If it
is not, do not continue driving.
Call for road side service or tow-
ing.
WARNING
If the inflation pressure is not
maintained, drive the vehicle a
second time, refer to Distributing
the sealant. Then repeat steps 1
to 4.
Use of the TMK may be ineffec-
tual for tire damage larger than
approximately 0.16 in (4 mm).
We recommend that you contact
an authorized HYUNDAI dealer if
the tire cannot be made road-
worthy with the Tire Mobility Kit.

Maintenance
Owner maintenance schedule
When you stop for fuel:
Check the engine oil level.
Check coolant level in the enginecoolant reservoir.
Check the windshield washer fluid level.
Check for low or under-inflated tires.
While operating your vehicle:
Note any changes in the sound ofthe exhaust or any smell of
exhaust fumes in the vehicle.
Check for vibrations in the steering wheel. Notice if there is any
increased steering effort or loose-
ness in the steering wheel, or
change in its straight-ahead posi-
tion.
Notice if your vehicle constantly turns slightly or "pulls" to one side
when traveling 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 operation of your transmission
occurs, check the transmission
fluid level.
Check the automatic transmission P (Park) function.
Check the parking brake.
Check for fluid leaks under your vehicle (water dripping from the air
conditioning system during or after
use is normal).
At least monthly:
Check coolant level in the enginecoolant reservoir.
Check the operation of all exterior lights, including the stoplights, turn
signals and hazard warning flashers.
Check the inflation pressures of all tires including the spare for tires
that are worn, show uneven wear,
or are damaged.
Check for loose wheel lug nuts.
Be careful when checking your
engine coolant level when the
engine is hot. This may result in
coolant being blown out of the
opening and cause serious
burns and other injuries.

Tire care
For proper maintenance, safety, and
maximum fuel economy, you must
always maintain recommended tire
inflation pressures and stay within
the load limits and weight distribution
recommended for your vehicle.
(Continued)Replace tires that are worn,
show uneven wear, or are dam-
aged. Worn tires can cause
loss of braking effectiveness,
steering) control, or traction.
ALWAYS replace tires with the
same size as each tire that
was originally supplied with
this vehicle. Using tires and
wheels other than the recom-
mended sizes could cause
unusual handling characteris-
tics, poor vehicle control, or
negatively affect your vehi-
cle’s Anti-Lock Brake System
(ABS) resulting in a serious
accident.
Tire failure may cause loss of
vehicle control resulting in an
accident. To reduce risk of
SERIOUS INJURY or DEATH,
take the following precautions:
Inspect your tires monthly for
proper inflation as well as
wear and damage.
The recommended cold tire
pressure for your vehicle can
be found in this manual and on
the tire label located on the dri-
ver’s side center pillar. Always
use a tire pressure gauge to
measure tire pressure. Tires
with too much or too little
pressure wear unevenly caus-
ing poor handling.
Check the pressure of the
spare every time you check
the pressure of the other tires
on your vehicle.
