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.

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 1to 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.
CAUTION

Towing service
If emergency towing is necessary,
we recommend having it done by an
authorized HYUNDAI dealer or a
commercial tow-truck service.
Proper lifting and towing procedures
are necessary to prevent damage to
the vehicle. The use of wheel dolliesor flatbed is recommended.It is acceptable to tow the vehicle
with the rear wheels on the ground(without dollies) and the front wheels
off the ground.
If any of the loaded wheels or sus- pension components are damaged
or the vehicle is being towed with the
front wheels on the ground, use a
towing dolly under the front wheels.
When being towed by a commercial
tow truck and wheel dollies are not
used, the front of the vehicle should
always be lifted, not the rear.

What to do in an emergency
Emergency Towing (if equipped)
If towing is necessary, we recom-
mend you to have it done by an
authorized HYUNDAI dealer or a
commercial tow truck service.If towing service is not available in an
emergency, your vehicle may be
temporarily towed using a cable or
chain secured to the emergency tow-
ing hook at the rear of the vehicle.
Use extreme caution when towing
the vehicle with a cable or chain. A
driver must be in the vehicle to steer
it and operate the brakes.
Towing should be done only on a
solid ground for a short distance and
at a low speed.
Also, the wheels, axles, power train,
steering and brakes must all be ingood condition.
Always follow these emergency tow-ing precautions:
Place the Engine Start/Stop button
in the ACC position so the steering
wheel is not locked.
Place the shift lever in N (Neutral).
Release the parking brake.
Depress the brake pedal with more force than normal since you will
have reduced braking perform-
ance.
More steering effort will be required because the power steer-
ing system will be disabled.
Use a vehicle heavier than your own to tow your vehicle.
The drivers of both vehicles should communicate with each other fre-
quently.
Before emergency towing, check that the hook is not broken or dam-aged.
Fasten the towing cable or chain securely to the hook.
Do not jerk the hook. Apply steady and even force.
