DRIVER ASSISTANCE SYSTEMS
Safety or driver assistance features are no 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 important feature limitations and information.
SAFETY ALERT SEATF – The driver’s seat pulses — left side, right side or simultaneously — to alert the driver of the direction of potential hazards.
Audible alerts or seat pulsing alerts may be selected. To change the alert settings, go to Settings > Vehicle > Collision/Detection > Alert Type.
LANE CHANGE ALERT WITH SIDE BLIND ZONE ALERTF – While driving, the system displays a warning symbol on the left or right side mirror when a vehicle is detected in that side blind zone area or rapidly approach-ing 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 > Lane Change Alert.
FORWARD COLLISION ALERTF – The
Vehicle Ahead Indicator is green when a
vehicle is detected and is amber when follow-ing 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 or rapid beeps sound (if selected).
Press the Collision Alert button on the steering wheel to set the alert timing to  Far,  Medium,  or Near.
FORWARD AUTOMATIC BRAKINGF – In potential front-end imminent collision situations with detected vehicles, the brakes may be applied, if you have not already done so, to help reduce damage or avoid collisions at very low speeds with vehicles directly ahead.
 To  set  the  Forward  Collision  Alert and Forward  Automatic  Braking  systems  to Alert  and Brake,  Alert, or Off,  go to Settings  > Vehicle  > Collision/Detection  > Forward  Collision System.
LANE KEEP ASSIST WITH LANE DEPARTURE WARNINGF – The system may help you avoid collisions 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 mark-ing 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 the Safety  Alert Seat may pulse or beeps may sound (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.

DRIVER ASSISTANCE SYSTEMS
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.  Turn off traction  control if the  vehicle  is stuck  and rocking  the vehicle  is required.
Press the Traction Control/StabiliTrak Off button on the center console to turn traction control on or off.
FRONT PEDESTRIAN BRAKINGF – During daytime driving, the system detects
pedestrians directly ahead up to a distance of approximately 131 feet and displays an amber indicator.  When approaching  a detected  pedestrian  too quickly,  a red  alert  flashes  on the windshield and the Safety Alert Seat pulses or rapid beeps sound (if selected). The system may prepare the brakes or automatically brake the vehicle, if you have not already done so.
 To  set  to Alert  and Brake,  Alert, or Off,  go to Settings  >  Vehicle  > Collision/Detection  > Front  Pedestrian  Detection.
FRONTF AND REAR VISION CAMERA – When the vehicle is in Reverse, a view of the area behind the vehicle displays on the infotainment screen. After shifting from Reverse to Drive, a view  of the  area  in front  of the   vehicle   displays.  Vehicle speed must be below  8 mph.
SURROUND VISIONF – The Surround Vision system displays a rear or front camera view along with a view of the area surrounding the vehicle on the infotainment screen when the vehicle is in Reverse or Drive below 5 mph.
Touch Front or Rear Camera on the camera screen to display the front or rear view.
Touch the Guidance Lines button  on the  camera  screen  to turn  the guidelines  on  or off.
FRONTF AND REARF PARK ASSIST – During low-speed parking maneuvers, the system provides “distance to closest object” information on the Driver Information Center and the Safety Alert Seat pulses or a beep sounds (if selected). When an object is very close, the Safety Alert Seat pulses or 5 beeps sound (if selected).
REAR CROSS TRAFFIC ALERTF – When the vehicle is in Reverse, the system warns of cross-traffic coming  in either  direction  by displaying  a red alert on the infotainment screen and the left or right side of the Safety Alert Seat pulses or beeps sound (if selected).
  To  turn  the Park  Assist  and Rear  Cross  Traffic  Alert systems  on or off,  press  the Park Assist button on the center console.
