Checking the Tire Inflation
Pressure
ODN8H070009NODN8H070009N
1. After driving approximately 4-6 miles
(7-10 km or about 10 min) stop at a
safe location.
2. Connect the filling hose (10) of the
compressor directly to the tire valve.
3. Connect between compressor and the
vehicle power outlet using the cable
and connectors.
4. Adjust the tire inflation pressure to the
recommended tire inflation.
With the vehicle in the ready (
)
mode, proceed as follows.
- To increase the inflation pressure:
Switch on the compressor.
To check the current inflation
pressure setting, briefly switch off
the compressor.
- To reduce the inflation pressure:
Press the button (9) on the
compressor.
NOTICE
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 compressor is
running. To get an accurate tire pressure,
the compressor needs to be turned off.
CAUTION
If the inflation pressure is not
maintained, drive the vehicle a second
time, refer to Distributing the sealant.
Then repeat steps 11 to 14.
Use of the TMK may be ineffectual for
tire damage larger than approximately
4 mm (0.16 in).
Contact an authorized HYUNDAI dealer
if the tire cannot be made roadworthy
with the Tire Mobility Kit.
WARNING
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 towing.
CAUTION
Tire pressure sensor
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 pressure sensors at an
authorized dealer.
Information
When reinstalling the repaired or replaced
tire and wheel on the vehicle, tighten the
wheel lug nut to 79-94 lbf·ft (11-13 kgf·m).

Emergency situations

Towing Service
ODN8H079010LODN8H079010L[A] : Dollies
If emergency towing is necessary, have 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 dollies or
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 suspension
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.
CAUTION
ODN8H079012ODN8H079012
• Do not tow the vehicle with the front
wheels on the ground as this may
cause damage to the vehicle.
ODN8H079011ODN8H079011
• Do not tow with sling-type
equipment. Use wheel lift or flatbed
equipment.
When towing your vehicle in an
emergency without wheel dollies:
1. Release EPB before turning off the
engine.
2. Press the Engine Start/Stop button to
the OFF position.
3. Shift the gear to N (Neutral).
For more details, refer to “Automatic
Transmission” section in chapter 6.
CAUTION
Failure to shift the gear to N (Neutral)
may cause internal damage to the
transmission.

16 feet
ODN8H079018ODN8H079018
• Use a towing cable or chain less than
16 feet (5 m) long. Attach a white or
red cloth (about 12 inches (30 cm)
wide) in the middle of the cable or
chain for easy visibility.
• Drive carefully so the towing cable or
chain remains tight during towing.
• Before towing, check the automatic
transmission for fluid leaks under your
vehicle. If the automatic transmission
fluid is leaking, flatbed equipment or a
towing dolly must be used.
NOTICE
Accelerate or decelerate the vehicle
in a slow and gradual manner while
maintaining tension on the tow rope
or chain to start or drive the vehicle,
otherwise tow hooks and the vehicle
may be damaged.
NOTICE
To avoid damage to your vehicle and
vehicle components when towing:
• Always pull straight ahead when
using the towing hooks. Do not pull
from the side or at a vertical angle.
• Do not use the towing hooks to pull
a vehicle out of mud, sand or other
conditions from which the vehicle
cannot be driven out under its own
power.
• Limit the vehicle speed to 10 mph
(15 km/h) and drive less than 1
mile (1.5 km) when towing to avoid
serious damage to the automatic
transmission.
