System Description

Blind-Spot Collision Warning (BCW)

The Blind-Spot Collision Warning (BCW) system uses radar sensors in the rear bumper to monitor and warn the driver of an approaching vehicle in the driver's blind spot area.

1) Blind-Spot Area

Hyundai Elantra. Blind-spot Collision Warning (BCW)

The blind spot detection range varies relative to vehicle speed.

Note that if your vehicle is traveling much faster than the vehicles around you, the warning will not occur.

2) Closing at high speed

The Lane Change Assist feature will alert you when it detects a vehicle is approaching in an adjacent lane at a high rate of speed. If the driver activates the turn signal when the system detects an oncoming vehicle, the system sounds an audible alert.

WARNING

  • Always be aware of road conditions while driving and be alert for unexpected situations even though the Blind- Spot Collision Warning (BCW) system is operating.
  • The Blind-Spot Collision Warning (BCW) system is supplemental systems to assist you. Do not entirely rely on the systems. Always pay attention, while driving, for your safety.
  • The Blind-Spot Collision Warning (BCW) system is not substitutes for proper and safe driving. Always drive safely and use caution when changing lanes or backing up the vehicle.
  • The Blind-Spot Collision Warning (BCW) system may not detect every object alongside the vehicle.

When this option is selected, the initial Blind-Spot 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

The system enters the ready status, when the following conditions are satisfied :

The vehicle speed is above approximately 20 mph (30 km/h).

Second stage alert

A warning chime to alert the driver will activate when:

1. A vehicle has been detected in the blind spot area by the radar system AND.

2. The turn signal is applied (same side as where the vehicle is being detected). When this alert is activated, the warning light on the outer side view mirror. Will also blink. And a warning chime will sound.

If you turn off the turn signal indicator, the second stage alert will be deactivated. If the detected vehicle is no longer within the blind spot area, the warning will turn off according to the driving conditions of the vehicle.

WARNING

  • The warning light on the outer side view mirror will illuminate whenever a vehicle is detected at the rear side by the system. To avoid accidents, do not focus only on the warning light and neglect to see the surroundings of the vehicle.
  • Drive safely even though the vehicle is equipped with a Blind-Spot Collision Warning (BCW) system. Do not solely rely on the system but check your surroundings before changing lanes or backing the vehicle up.
  • The system may not alert the driver in some situations due to system limitations so always check your surroundings while driving.

CAUTION

  • 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 Blind-Spot Collision Warning system warning sounds.
  • If any other warning sound such as seat belt warning chime is already generated, the Blind-Spot Collision Warning (BCW) system warning may not sound.

Detecting Sensor

Hyundai Elantra. 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 sensing range differs somewhat according to the width of the road. When the road is narrow, the system may detect other vehicles in the next lane.
  • 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

Hyundai Elantra. 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.
