Driver Assistance Systems
This vehicle may have features that work together to help avoid crashes or reduce crash damage while driving, backing up, and parking. Read this entire section before using these systems.
- Detect children, pedestrians, bicyclists, or animals.
- Detect vehicles or objects outside the system's field of view.
- Operate at all driving speeds.
- Alert you or provide you with enough time to avoid a crash.
- Operate in poor visibility or bad weather conditions.
- Operate if the detection sensor is not clean or is covered with ice, snow, dirt, or mud.
- Operate if the detection sensor is covered, such as by a sticker, magnet, or metal plate.
- Operate if the area around the detection sensor is damaged or improperly repaired.
Full attention is always required while driving, and you must be ready to act and use the brakes and/or steer the vehicle to avoid crashes.
Audible or Seat Alerts
Some driver assistance features alert the driver to obstacles with beeps. To change the volume of the warning chime, see Comfort and Convenience in the Vehicle Personalization section.
If equipped with a safety alert seat, the driver seat cushion may provide a vibration alert instead of an audible chime. To change this, see Crash Detection Systems in the Vehicle Personalization section.
