Kia Optima Hybrid 2017 Owner's Manual page 536

When the tire pressure monitoring sys‐
tem warning indicators are illuminated
and warning massage displayed on the
cluster LCD display, one or more of
your tires is significantly under-infla‐
ted. The low tire pressure position tell‐
tale light will indicate which tire is sig‐
nificantly under-inflated by illuminating
the corresponding position light.
If either telltale illuminates, immediate‐
ly reduce your speed, avoid hard cor‐
nering and anticipate increased stop‐
ping distances. You should stop and
check your tires as soon as possible. In‐
flate 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 a
spare tire.
If you drive the vehicle for about 10 mi‐
nutes at speeds above 25 km/h after
replacing the low pressure tire with the
spare tire, one of the following will hap‐
pen:
• The TPMS malfunction indicator may
blink for approximately 1 minute and
then remain continuously illuminated
because the TPMS sensor is not
mounted on the spare wheel.
(changed tire equipped with a sensor
not in the vehicle)
• The TPMS malfunction indicator will
remain continuously illuminated while
driving because the TPMS sensor is
not mounted on the spare wheel.
(changed tire equipped with a sensor
in the vehicle)
CAUTION
In winter or cold weather, the low
tire pressure telltale may illuminate
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 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 higher or
lower, you should check the tire in‐
flation pressure and adjust the tires
(Continued)
(Continued)
to the recommended tire inflation
pressure.
WARNING
n Low pressure damage
Significantly low tire pressure makes
the vehicle unstable and can contrib‐
ute to loss of vehicle control and in‐
creased 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 indi‐
cator will illuminate after it blinks for
approximately one minute when there
is a problem with the Tire Pressure
Monitoring System.
We recommend that the system be
checked by an authorized Kia dealer to
determine the cause of the problem.
