What to do in an emergency
NOTICE
The spare tyre is not equipped
with a tyre pressure sensor.
CAUTION
In winter or cold weather, the
low tyre pressure telltale may
illuminate if the tyre pressure
was adjusted to the recom-
mended tyre inflation pressure
in warm weather. It does not
mean your TPMS is malfunc-
tioning because the decreased
temperature leads to a lowering
of tyre 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 higher or lower, you should
check the tyre inflation pres-
sure and adjust the tyres to the
recommended tyre
pressure.

Low pressure damage
Significantly low tyre pressure
makes the vehicle unstable and
can contribute to loss of vehicle
control and increased braking
distances.
Continued driving on low pres-
sure tyres can cause the tyres
to overheat and fail.

WARNING
TPMS (Tyre Pressure
Monitoring System)
malfunction indicator
The TPMS malfunction indicator will
illuminate after it blinks for approxi-
mately one minute when there is a
problem with the Tyre Pressure
Monitoring System.
We recommend that the system be
checked by a HYUNDAI authorised
repairer.
NOTICE
If there is a malfunction with the
TPMS, the low tyre pressure posi-
tion telltale will not be displayed
even though the vehicle has an
under-inflated tyre.
