Driving your vehicle
Rear/side detecting sensors
The sensors are located inside the
rear bumper for detecting rear / side
areas.
Always keep the rear bumper clean
for proper operation of the system.
OJFH058150
CAUTION
• The system may not work
properly when the bumper has
been damaged, or if the rear
bumper has been replaced or
repaired.
• The sensing range differs
somewhat according to the
width of the road. When the
road is narrow, the system
may detect and alert to other
vehicles in the next lane.
• On the contrary, on wide
roads, the system may not be
able to detect an automobile
that is driving on surrounding
lanes and may not be able to
alert.
• The system may turn off due if
interfered by electromagnetic
interference.
• Always keep the sensors and
bumpers near the sensor
clean.

• Never disassemble the sensor
component nor apply any
impact on the sensor compo-
nent.
• Be careful not to apply unnec-
essary force on the radar sen-
sors or bumpers near the sen-
sor. If the sensor is forcibly
moved out of proper align-
ment, the system may not
operate correctly. In this case,
have the system checked by
an authorized Kia dealer.
• Do not apply foreign objects
such as a bumper sticker or a
bumper guard near the radar
sensor or apply paint to the
sensor area. Doing so may
adversely affect the perform-
ance of the sensor.
