WARNING
Drive safely even though thevehicle is equipped with a
Rear Cross-Traffic Collision
Warning (RCCW) System. Do
not solely rely on the system
but check your surrounding
when backing the vehicle up.
The RCCW system may not
detect every object alongside
the vehicle.
The driver is responsible for accurate brake control.
Always pay extreme caution while driving. The Rear Cross-
Traffic Collision Warning
System may not operate prop-
erly or unnecessarily operate
in accordance with your driv-
ing situations.
CAUTION
If the operating conditions of RCCW are satisfied, a warningis issued every time a vehiclecomes to the rear side, even ifyour vehicle is stopped (vehi-cle speed 0 km/h (0 mph)).
The system's warning may not operate properly if theleft/right of your vehicle's rearbumper is blocked by a vehi-cle or obstacle.
The driver should always use extreme caution while operat-ing the vehicle, whether or notthe warning light on the out-side rearview mirror illumi-nates or there is a warningalarm.

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 workproperly when the bumper hasbeen damaged, or if the rearbumper has been replaced orrepaired.
The sensing range differs somewhat according to thewidth of the road. When theroad is narrow, the systemmay detect and alert to othervehicles in the next lane.
On the contrary, on wide roads, the system may not beable to detect an automobilethat is driving on surroundinglanes and may not be able toalert.
The system may turn off due if interfered by electromagneticinterference.
Always keep the sensors and bumpers near the sensorclean.
(Continued)
(Continued)
Never disassemble the sensor component nor apply anyimpact 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 forciblymoved out of proper align-ment, the system may notoperate correctly. In this case,have the system checked byan authorized Kia dealer.
Do not apply foreign objects such as a bumper sticker or abumper guard near the radarsensor or apply paint to thesensor area. Doing so mayadversely affect the perform-ance of the sensor.
