2014 KIA Optima brake sensor

355
Safety features of your vehicle
Just before impact, drivers oftenbrake heavily. Such heavy braking
lowers the front portion of the vehi-
cle causing it to “ride” under a vehi-
cle with a higher ground clearance.
Air bags may not inflate in this
"under-ride" situation because
deceleration forces that are detect-
ed by sensors may be significantly
replaced by such “under-ride” colli-
sions. Air bags may not inflate in rollover
accidents because the vehicle can
not detect rollover accident.
However, side and/or curtain air
bags may inflate when the vehicle
is rolled over following (or after)
side impact collision. Air bags may not inflate if the vehi-
cle collides with objects such as
utility poles or trees, where the
point of impact is concentrated to
one area and the full force of the
impact is not delivered to the sen-
sors.

Non-operational conditions of
back-up warning system
The back-up warning system may
not operate properly when:
1. Moisture is frozen to the sensor. (It
will operate normally when the
moisture has been cleared.)
2. The sensor is covered with foreign matter, such as snow or water, or
the sensor cover is blocked. (It will
operate normally when the materi-
al is removed or the sensor is no
longer blocked.)
3. Driving on uneven road surfaces. (unpaved roads, gravel, bumps,
gradient.)
4. Objects generating excessive noise (vehicle horns, loud motor-
cycle engines, or truck air brakes)
are within range of the sensor.
5. Heavy rain or water spray exists.
6. Wireless transmitters or mobile phones are within range of the
sensor.
7. The sensor is covered with snow.
8. Trailer towing. The detecting range may decrease
when:
1. The sensor is stained with foreign
matter such as snow or water.
(The sensing range will return to
normal when removed.)
2. Outside air temperature is extremely hot or cold.
The following objects may not be
recognized by the sensor:
1. Sharp or slim objects such as ropes, chains or small poles.
2. Objects which tend to absorb the sensor frequency such as clothes,
spongy material or snow.
3. Undetectable objects smaller than 1 m (40 in.) in height and narrower
than 14 cm (6 in.) in diameter.
back-up warning system pre-
cautions
The back-up warning system maynot sound sequentially depending
on the speed and shapes of the
objects detected.
The back-up warning system may malfunction if the vehicle bumper
height or sensor installation has
been modified or damaged. Any
non-factory installed equipment or
accessories may also interfere with
the sensor performance.
The sensor may not recognize objects less than 30 cm (11 in.)
from the sensor, or it may sense an
incorrect distance. Use caution.
When the sensor is frozen or stained with snow, dirt, or water, the sensor
may be inoperative until the stains
are removed using a soft cloth.
Do not push, scratch or strike the sensor. Sensor damage could occur.
