Hyundai Elantra AD: Rear Cross-traffic Collision Warning (RCCW) System
System Description
Rear Cross-Traffic Collision Warning (RCCW) system
The Rear Cross-Traffic Collision Warning (RCCW) system uses radar sensors to monitor the approaching cross traffic from the left and right side of the vehicle when your vehicle is in reverse.
The blind spot detection range varies relative to the approaching vehicle speed.
WARNING
- Always be aware of road and traffic conditions while driving and be alert for unexpected situations even though the Rear Cross-Traffic Collision Warning system is operating.
- The Rear Cross-Traffic Collision Warning system is supplemental systems to assist you. Do not entirely rely on the systems. Always pay attention, while driving, for your safety.
- The Rear Cross-Traffic Collision Warning system is not substitutes for proper and safe driving. Always drive safely and use caution when backing up the vehicle.
System Setting and Operation
System setting
• Setting Blind-Spot Safety function
The driver can activate the systems by placing the ignition switch to the ON position and by selecting 'User Settings → Driver Assistance → Blind-Spot Safety → Rear Cross-Traffic Safety'. The RCCW turns on and gets ready to be activated when 'Rear Cross-Traffic Safety' is selected.
• When the engine is turned off then on again, the systems always get ready to be activated.
• When the system is initially turned on and when the engine is turned off then on again, the warning light will illuminate for 3 seconds on the outside rearview mirror.
• Setting Warning Timing
The driver can select the initial warning activation time in the User Settings in the LCD display by selecting 'User Settings → Driver Assistance → Warning Timing'.
The options for the initial Rear Cross-Traffic Collision Warning includes the following:
- Normal:
When this option is selected, the initial Rear Cross-Traffic Collision Warning is activated normally. If this setting feels sensitive, change the option to 'Later'.
The warning activation time may feel late if a vehicle at the side or rear abruptly accelerates.
- Later:
Select this warning activation time when the traffic is light and you are driving in a low speed.
Information
If you change the warning timing, the warning time of other systems may change. Always be aware before changing the warning timing.
Operating conditions
To operate:
Go to the 'User Settings → Driver Assistance → Blind-Spot Safety → Rear Cross-Traffic Safety' in the cluster LCD display. The system will turn on and standby to activate.
The system will operate when vehicle speed is below 10 km/h (7 mph) and with the shift lever in R (Reverse).
* The system will not operate when the vehicle speed exceeds 10 km/h (7 mph). The system will activate again when the speed is below 10 km/h (7 mph).
The system's detecting range is approximately 1 - 65 ft (0.5 – 20 m). An approaching vehicle will be detected if their vehicle speed is within 2.5 - 22.5 mph (4 - 36 km/h).
Note that the detecting range may vary under certain conditions. As always, use caution and pay close attention to your surroundings when backing up your vehicle.
Warning and system control
Rear Cross-Traffic Collision Warning (RCCW) system
If the vehicle detected by the sensors approaches from the rear left/right side of your vehicle, the warning chime will sound, the warning light on the outside rearview mirror will blink and a warning will appear on the LCD display. If the rear view monitor system is in activation, a warning will also appear on the audio or AVN screen.
The warning will stop when:
- the detected vehicle moves out of the sensing area or
- when the vehicle is right behind your vehicle or
- when the vehicle is not approaching your vehicle or
- when the other vehicle slows down.
CAUTION
- When the operation condition of the Rear Cross-Traffic Collision Warning system is satisfied, the warning will occur every time a vehicle approaches the side or rear of your stopped (0 mph vehicle speed) vehicle.
- The system's warning may not operate properly if the left or right of your vehicle's rear bumper is blocked by a vehicle or obstacle.
- Always pay attention to road and traffic conditions while driving, whether or not the warning light on the outside rearview mirror illuminates or there is a warning alarm.
- Playing the vehicle audio system at high volume may prevent occupants from hearing the system's warning sounds.
- If any other warning sound such as seat belt warning chime is already generated, the Rear Cross-Traffic Collision Warning system warning may not sound.
WARNING
- Drive safely even though the vehicle is equipped with a Rear Cross-Traffic Collision Warning system. Do not solely rely on the system but check your surrounding when backing the vehicle up.
- The driver is responsible for accurate brake control.
- Always pay extreme caution while driving. The Rear Cross- Traffic Collision Warning system may not operate properly or unnecessarily operate depending on traffic and driving conditions.
- The Rear Cross-Traffic Collision Warning system is not a substitute for safe driving practices, but a convenience function only. It is the responsibility of the driver to always drive cautiously to prevent unexpected and sudden situations from occurring. Pay attention to the road conditions at all times.
Detecting sensor
The rear radars are located inside the rear bumper for detecting the side and rear areas. Always keep the rear bumper clean for proper operation of the system.
NOTICE
- The system may not work properly when the bumper has been damaged, or if the rear bumper has been replaced or repaired.
- The system may turn off if interfered by electromagnetic waves.
- Always keep the sensors clean.
- NEVER disassemble the sensor component or apply any impact on the sensor component.
- Be careful not to apply unnecessary force on the radar sensor or sensor cover. If the sensor is forcibly moved out of proper alignment, the system may not operate correctly. In this case, a warning message may not be displayed. Have the vehicle inspected by an authorized HYUNDAI 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 performance of the sensor.
Warning message
Blind-Spot Collision Warning (BCW) system disabled. Radar blocked
This warning message may appear when:
- One or both of the sensors on the rear bumper is blocked by dirt or snow or
a foreign object.
- Driving in rural areas where the sensor does not detect another vehicle for an
extended period of time.
- When there is inclement weather such as heavy snow or rain.
If any of these conditions occur, the light on the BCW switch and the system will turn off automatically.
When the BCW canceled warning message is displayed in the cluster, check to make sure that the rear bumper is free from any dirt or snow in the areas where the sensor is located. Remove any dirt, snow, or foreign material that could interfere with the radar sensors.
After any dirt or debris is removed, the system should operate normally after about 10 minutes of driving the vehicle.
If the system still does not operate normally have your vehicle inspected by an authorized HYUNDAI dealer.
Check Blind-Spot Collision Warning (BCW) system
If there is a problem with the BCW system, a warning message will appear and the light on the switch will turn off. The system will turn off automatically. RCCW will not operate also if the BCW system turns off due to malfunction. Have your vehicle inspected by an authorized HYUNDAI dealer.
