Hyundai Sonata: Automatic emergency braking (AEB) / AEB warning message and system control

The AEB produces warning messages and warning alarms in accordance with the collision risk levels. Also, it controls the brakes in accordance with the collision risk levels.

Forward Warning (1st warning)

This initial warning message appears on the LCD display with a warning chime.

The driver can select the initial warning activation time in the User Settings in the Driver LCD display. The options for the initial Forward Collision Warning include FAST, NORMAL, or SLOW initial warning time.

Collision Warning (2nd warning)

• This warning message appears on the LCD display with a warning chime.
• Additionally, some vehicle system intervention occurs by the engine management system to help decelerate the vehicle.
  - If the detected vehicle in front is driving slower than 50 mph (80 km/h), your vehicle speed may decelerate sharply to avoid a collision. If the detected vehicle in front is driving faster than 50 mph (80 km/h), your vehicle speed may decelerate moderately.
  - If your vehicle is traveling less than 40 mph (65 km/h) and a pedestrian is detected within the Collision Warning (2nd warning) stage, your vehicle speed may decelerate sharply to avoid a collision.

Emergency braking (3rd warning)

• This warning message appears on the LCD display with a warning alarm.
• Additionally, automatic emergency braking of the vehicle is applied in order to avoid a collision.
  - If your vehicle is traveling less than 40 mph (65 km/h) and a pedestrian is detected within the Emergency Braking stage, automatic emergency braking of the vehicle is applied. In this condition, your vehicle speed will decelerate sharply to avoid a collision.
  - When your vehicle drives slower than 40 mph (65 km/h) with a passer-by in front, the driving speed may abruptly decrease. When your vehicle drives faster than 40 mph (65 km/h) with a pedestrian in front, the AEB does not operate.

Brake operation

• In an urgent situation, the braking system enters into the ready status for prompt reaction against the driver’s depressing the brake pedal.
• The AEB provides additional braking power for optimum braking performance, when the driver depresses the brake pedal.
• The braking control is automatically deactivated, when the driver sharply depresses the brake pedal, or when the driver abruptly operates the steering wheel.
• The braking control is automatically canceled, when risk factors disappear.

CAUTION

The driver should always use extreme caution while operating the vehicle, whether or not there is a warning message or alarm from the AEB system.

WARNING

The braking control cannot completely stop the vehicle nor avoid all collisions. The driver should hold the responsibility to safely drive and control the vehicle.

WARNING

The AEB system logic operates within certain parameters, such as the distance from the vehicle or pedestrian ahead, the speed of the vehicle ahead, and the driver's vehicle speed. Certain conditions such as inclement weather and road conditions may affect the operation of the AEB system.
