Emergency Situations8-14
Low Tire Pressure
Warning Light
Low Tire Pressure Position and
Tire Pressure Telltale
ONX4E040019
When the tire pressure monitoring
system warning indicators are
illuminated and a warning message
displayed on the cluster LCD display,
one or more of your tires is significantly
under-inflated. The Low Tire Pressure
Position Telltale will indicate which
tire is significantly underinflated by
illuminating the corresponding position
light.
If either telltale illuminates, immediately
reduce your speed, avoid hard cornering
and anticipate increased stopping
distances. You should stop and check
your tires as soon as possible. Inflate the
tires to the proper pressure as indicated
on the vehicle’s placard or tire inflation
pressure label located on the driver’s
side center pillar 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.
The Low Tire Pressure Telltale will remain
on and the TPMS Malfunction Indicator
may blink for one minute and then
remain illuminated (when the vehicle
is driven approximately 10 minutes at
speed above 15.5 mph (25 km/h)) until
you have the low pressure tire repaired
and replaced on the vehicle.
CAUTION
In winter or cold weather, the Low Tire
Pressure Telltale may be illuminated if
the tire pressure was adjusted to the
recommended tire inflation pressure
in warm weather. It does not mean
your TPMS is malfunctioning because
the decreased temperature leads to a
proportional lowering of tire pressure.
When you drive your vehicle from a
warm area to a cold area or from a cold
area to a warm area, or the outside
temperature is greatly higher or lower,
you should check the tire inflation
pressure and adjust the tires to the
recommended tire inflation pressure.
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 pressure tires
can cause the tires to overheat and fail.

TPMS (Tire Pressure
Monitoring System)
malfunction indicator
The TPMS Malfunction Indicator
will illuminate after it blinks for
approximately one minute when there
is a problem with the Tire Pressure
Monitoring System.
Have the system checked by an
authorized HYUNDAI dealer as soon as
possible.
NOTICE
If there is a malfunction with the TPMS,
the Low Tire Pressure Position Indicator
will not be displayed even though the
vehicle has an under-inflated tire.
NOTICE
The TPMS Malfunction Indicator may
illuminate after blinking for one minute
if the vehicle is near electric power
supply cables or radio transmitters
such as police stations, government
and public offices, broadcasting
stations, military installations, airports,
transmitting towers, etc.
Additionally, the TPMS Malfunction
Indicator may illuminate if snow chains
are used or electronic devices such as
computers, chargers, remote starters,
navigation, etc. This may interfere with
normal operation of the TPMS.
Changing a Tire with TPMS
If you have a flat tire, the Low Tire
Pressure and Position indicators will
come on. Have the flat tire repaired by an
authorized HYUNDAI dealer as soon as
possible or replace the flat tire with the
spare tire.
NOTICE
It is recommended that you do not
use a puncture-repairing agent not
approved by HYUNDAI dealer or the
equivalent specified for your vehicle to
repair and/or inflate a low pressure tire.
Tire sealant not approved by HYUNDAI
dealer or the equivalent specified for
your vehicle may damage the tire
pressure sensor.
The spare tire (if equipped) does not
come with a tire pressure monitoring
sensor. When the low pressure tire or
the flat tire is replaced with the spare
tire, the Low Tire Pressure Indicator will
remain on. Also, the TPMS Malfunction
Indicator will illuminate after blinking
for one minute if the vehicle is driven
at speed above 15.5 mph (25 km/h) for
approximately 10 minutes.
Once the original tire equipped with
a tire pressure monitoring sensor is
reinflated to the recommended pressure
and reinstalled on the vehicle, the
Low Tire Pressure Indicator and TPMS
Malfunction Indicator will go off within a
few minutes of driving.
If the indicators do not extinguish after
a few minutes, contact an authorized
HYUNDAI dealer.
Each wheel is equipped with a tire
pressure sensor mounted inside the tire
behind the valve stem (except for the
spare tire). You must use TPMS specific
wheels. It is recommended that you
always have your tires serviced by an
authorized HYUNDAI dealer.

Emergency Situations8-22
9. With the vehicle ON ( indicator ON), switch on
the compressor and let it run for
approximately 5~7 minutes to fill
the sealant up to proper pressure.
(Refer to “Tire and Wheels” section
in chapter2). 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.
CAUTION
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.
10. Switch off the compressor.
11. Detach the hoses from the sealant bottle connector and from the tire
valve.
Return the Tire Mobility Kit to its storage
location in the vehicle.
WARNING
Do not leave your vehicle running in
a poorly ventilated area for extended
periods of time. Carbon monoxide
poisoning and suffocation can occur.
Distributing the sealant
OOSH079022L
12. Immediately drive approximately 4~6 miles (7~10 km 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.
Call for road side service or towing.

Emergency Situations8-24
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
0.16 in (4 mm).
Contact an authorized HYUNDAI dealer
if the tire cannot be made roadworthy
with the Tire Mobility Kit.
WARNING
The tire inflation pressure must be
inflated to the proper pressure (Refer to
“Tire and Wheels” section in chapter 2).
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. Get
this done at an authorized dealer.
Information
When reinstalling the repaired or replaced
tire and wheel on the vehicle, tighten the
wheel nut to 11~13 kgf·m (79~94 lbf·ft).

„Rear
ONX4H080002
If towing is necessary, have it done by
an authorized HYUNDAI dealer or a
commercial tow truck service.
If a towing service is not available in
an emergency, your vehicle may be
temporarily towed using a cable or chain
secured to the emergency towing hook
at the front (or 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 in this manner may be done
only on hard-surfaced roads for a short
distance and at low speeds. Also, the
wheels, axles, power train, steering and
brakes must all be in good condition.
CAUTION
The driver must be in the vehicle for
steering and braking operations when
the vehicle is being towed. Passengers
other than the driver must not be in the
vehicle.
Always follow these emergency towing
precautions:

[Place the ignition switch in the ACC
position so the steering wheel is not
locked.

[ Place the shift button in N (Neutral).

[ Release the parking brake.

[ Depress the brake pedal with more
force than normal as you will have
reduced braking performance.

[ More steering effort will be required
because the power steering 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
frequently.

[ Before emergency towing, check that
the hook is not broken or damaged.

[ Fasten the towing cable or chain
securely to the hook.

[ Do not jerk the hook. Apply steady
and even force.
