Changing a Tire with TPMS

If you have a flat tire, the Low Tire
Pressure and Position telltales 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 (if equipped).
NOTICE
It is recommended that you do not use a
puncture-repairing agent not approved
by a HYUNDAI dealer to repair and/or
inflate a low pressure tire. Tire sealant
not approved by a HYUNDAI dealer 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 LCD position
indicator will remain on. Also, the TPMS
Malfunction Indicator will illuminate after
blinking for one minute if the vehicle is
driven at speed above 25 km/h(15.5 mph)
for approximately 20 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 Telltale and TPMS
Malfunction Indicator will go off within a
few minutes of driving.
If the indicators do not extinguish after a
few minutes, please visit 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.
