!
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 pres-
sure 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 significantly
increases or decreases, 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 contrib-
ute to loss of vehicle control and
increased braking distances.
Continued driving on low pressure
tires will cause the tires to overheat
and fail.
WHAT TO DO IN AN EMERGENCY
TPMS (Tire pressure moni-
toring system) malfunction
The TPMS malfunction indicator comes
on and stays on when there is a problem
with the Tire Pressure Monitoring Sys-
tem. If the Front Left sensor fails, the
TPMS malfunction indicator illuminates,
but if the Front Right, Rear Left, or Rear
Right tire is under-inflated, the low tire
pressure and position telltales may illu-
minate together with the TPMS mal-
function indicator.
Have the system checked by an autho-
rized Hyundai dealer as soon as pos-
sible to determine the cause of the
problem.
