What to do in an emergency
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 25 km/h
(15.5 mph)) until you have the low
pressure tire repaired and replaced
on the vehicle.
✽ NOTICE
The spare tire is not equipped with a
tire pressure sensor.
CAUTION
In winter or cold weather, the
Low Tire Pressure Telltale may
be illuminated if the tire pres-
sure was adjusted to the recom-
mended tire inflation pressure
in warm weather. It does not
mean your TPMS is malfunction-
ing because the decreased tem-
perature leads to a proportional
lowering of tire pressure.

(Continued)
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
• 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 Malfunction
Indicator
The TPMS Malfunction Indicator
comes on after it blinks for approxi-
mately 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 to determine the cause
of the problem.
✽ NOTICE
The TPMS Malfunction Indicator
may illuminate after blinking for one
minute if the vehicle is near electric
power supply cables or radio trans-
mitters such as police stations, gov-
ernment and public offices, broad-
casting 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.
