DRIVER ASSISTANCE SYSTEMS
F Optional equipment
Safety or driver assistance features are not a substitute for the driver’s responsibility to operate the vehicle in a safe manner. The driver should remain attentive to traffic, surroundings and road conditions at all times. Read your Owner’s Manual for more important feature limitations and information.
Safety Alert Seat — The driver’s seat pulses (left, right, or both sides) to alert you of the direction of potential hazards.
Audible alerts may be selected instead of seat pulsing alerts. To change the alert
settings, go to Settings > Vehicle > Collision/Detection Systems > Alert Type.
Forward Collision Alert — The Vehicle Ahead indicator is green when a vehicle that you’re following is detected ahead and is amber when you’re following a vehicle ahead much too closely. When approaching a vehicle directly ahead too rapidly, a red alert flashes on the windshield or in the HUDF and rapid beeps sound or the Safety Alert Seat pulses (if selected).
Press the Forward Collision Alert button on the steering wheel to set the alert tim-ing to Far, Medium, or Near. The setting is displayed on the Driver Information Center.
Automatic Emergency Braking — In detected, potentially imminent collision situations with vehicles being followed directly ahead, the system can provide alerts and enhance driver braking or automatically apply hard emergency braking, if you have not already done so, to help reduce the severity or help avoid collisions at very low speeds. The system works at speeds below 50 mph.
To set Automatic Emergency Braking and Forward Collision Alert to Alert and Brake, Alert, or Off, go to Settings > Vehicle > Collision/Detection Systems > Forward Collision System.
Front Pedestrian Braking — During daytime
driving, the system can detect pedestrians directly ahead and displays an amber indica-tor. When approaching a detected pedestrian too quickly, a red alert flashes on the windshield or in the HUDF and rapid beeps sound or the Safety Alert Seat pulses (if selected). The system may automatically provide hard emergency braking or enhance the driver’s hard braking. The system works at speeds below 50 mph. Nighttime and low-visibility performance is limited.
To set the system to Alert and Brake, Alert, or Off, go to Settings > Vehicle > Collision/Detection Systems > Front Pedestrian Detection.
Lane Keep Assist with Lane Departure Warning — The system may help you avoid col-lisions due to unintentional lane departures. The Lane Keep Assist indicator is green 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 displaying an amber . If active driver steering is not detected, the amber may flash and beeps may sound or the Safety Alert Seat may pulse (if selected) on the side of the departure direction as the lane marking is crossed. The Lane Keep Assist system does not continuously steer the vehicle, the driver needs to steer and be in complete control of the vehicle.
To turn on or off, press the Lane Keep Assist button on the center console.
See Driving and Operating in your Owner’s Manual.

DRIVER ASSISTANCE SYSTEMS
F Optional equipment
Traction Control and StabiliTrak — The full-time traction control system limits wheelspin and the StabiliTrak electronic 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. Traction control should be turned off if the vehicle is stuck and rocking the vehicle is required.
To turn traction control on or off, press the Traction Control/StabiliTrak Off button (A) on the center console.
Lane Change Alert with Side Blind Zone Alert — While driving, the system displays a warn-ing symbol on the left or right side mirror when a vehicle is detected in that side blind zone area or rapidly approaches that area. The warning symbol flashes if a turn signal is activated when a vehicle has been detected on the same side.
To turn on or off, go to Settings > Vehicle > Collision/Detection Systems > Lane Change Alert.
Rear Cross Traffic Alert — When in Reverse, the system warns of detected cross-traffic approaching in either direction by displaying a red alert on the infotainment screen and beeps sound or the Safety Alert SeatF pulses (if selected).
To turn on or off, go to Settings > Vehicle > Collision/Detection Systems > Rear Cross Traffic Alert.
FrontF and Rear Park Assist — During low-speed parking maneuvers, the system provides “distance to closest object” information on the Driver Information Center and beeps sound or the Safety Alert SeatF pulses (if selected). When an object is very close, 5 beeps sound or the Safety Alert SeatF pulses (if selected).
To turn on or off, press the Park Assist button (B) on the center console.
HD Rear Vision Camera — When in Reverse below 8 mph, a view of the area behind the vehicle displays on the infotainment screen.
HD Surround VisionF — HD Surround Vision uses multiple cameras to display an overhead image of the area around the vehicle with Rear Vision Camera or other selectable views. It works at low speeds and can help when parking.
Touch one of the camera view buttons on the infotainment screen to change the camera view.
To turn the guidance lines on or off, touch the Guidance Lines button.
See Driving and Operating in your Owner’s Manual.
