Driver Assistance Systems

The driver assistance systems use advanced technologies to help avoid collisions by providing visual and audible alerts under some imminent collision conditions.

Safety Alert Seat – The driver's seat pulses, left side, right side, or simultaneously, to alert the driver of potential hazards.

• Audible notification may be selected instead of Safety Alert Seat pulsing notification. To change the alert setting, go to Settings > Vehicle > Collision/Detection Systems > Alert Type.
  
  Optional equipment

Forward Collision Alert – The Vehicle Ahead indicator is green on the instrument cluster when a vehicle is detected and is amber when following a vehicle ahead much too closely. When approaching a vehicle directly ahead too rapidly, a red alert flashes on the windshield and the Safety Alert Seat pulses.

• Press the Collision Alert button on the left side of the steering wheel to set the alert sensitivity to Far, Medium, Near, or Off.

Low-Speed Forward Automatic Braking (LD models only) – If the vehicle is traveling at a low speed and the system detects that a front-end collision situation is imminent while following a detected vehicle, and the driver has not already applied the brakes, the system automatically applies the brakes to help reduce the collision's severity. The system may even help avoid the collision at very low speeds.

• To turn the system on or off, go to Settings > Vehicle > Collision/Detection Systems > Auto Collision Preparation.

Lane Keep Assist with Lane Departure Warning (LD Models Only) – The system may help avoid collisions due to unintentional lane departures. The Lane Keep Assist indicator is green on the instrument cluster if the system is available to assist. If the vehicle approaches a detected lane marking without using a turn signal in that direction, the system may assist by gently turning the steering wheel and display an amber .

If active driver steering is not detected, the amber may flash and the Safety Alert Seat may pulse 3 times, or 3 beeps may sound, on the side of the departure direction as the lane marking is crossed. In order to use this system safely, the driver needs to steer and be in complete control of the vehicle.

• Press the Lane Keep Assist button on the center of the instrument panel to turn the system on or off.

Lane Departure Warning (HD Models Only) – When crossing a detected lane marking without using a turn signal, the system flashes an amber visual alert on the instrument cluster and pulses the left or right side of the Safety Alert Seat.

• Press the Lane Departure Warning button on the center of the instrument panel to turn the system on or off.

Rear Vision Camera – Provides a view directly behind the vehicle when backing up.

• To turn the Rear Vision Camera Guidelines or Rear Park Assist Symbols on or off, go to Settings > Rear Camera.

Driver Assistance Systems

Front and/or Rear Parking Assist – During low-speed parking maneuvers, the system provides "distance to closest object" information on the Driver Information Center and a caution symbol on the Rear Vision Camera display. When the vehicle should be stopped immediately to avoid a collision, a continuous audible tone sounds or the Safety Alert Seat pulses.

• To turn the system on or off, press the Parking Assist button on the center of the instrument panel.

See Driving and Operating in your Owner Manual.

Traction Control and StabiliTrak Systems

The traction control system limits wheelspin and the StabiliTrak® stability control system assists with directional control of the vehicle in difficult driving conditions. Both systems turn on automatically every time the vehicle is started.
