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.
To turn the following driver assistance systems on/off or to change the system settings, go to Settings > Vehicle > Collision/Detection Systems on the infotainment screen.
SAFETY ALERT SEATF – 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.
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 moving vehicle is detected rapidly approaching or is in a side blind zone. The symbol flashes if a turn signal is activated when a vehicle has been detected on the same side.
AUTOMATIC EMERGENCY BRAKING – In detected potential imminent collision
situations with vehicles 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.
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 detected 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 Forward Collision Alert button on the steering wheel to set the alert timing to Far, Medium, or Near.
FRONT PEDESTRIAN BRAKING – During daytime driving, the system detects pedes-trians directly ahead and displays an amber indicator on the instrument cluster. When approaching a detected pedestrian too quickly, a red alert flashes on the wind-shield and the Safety Alert Seat pulses or rapid beeps sound (if selected). The system may prepare the brakes or automatically apply hard emergency braking, if you have not already done so.
REAR PEDESTRIAN ALERTF – During daytime driving with the vehicle in Reverse, the system can detect pedestrians directly behind the vehicle and will display an amber indicator on the infotainment screen. When a pedestrian is detected close to the vehicle, the indicator flashes red and the Safety Alert Seat pulses or rapid beeps sound (if selected).
LANE KEEP ASSIST WITH LANE DEPARTURE WARNINGF – The system may help avoid collisions due to unintentional lane departures. The Lane Keep Assist indica-tor 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 providing brief, gentle steering wheel turns and displaying an amber indicator. If active driver steering is not detected, the amber indicator 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. In order to use this system safely, the driver needs to steer and be in complete control of the vehicle.
To turn the system on or off, press the Lane Keep Assist button on the left side of the instrument panel.See Driving and Operating in your Owner’s Manual.

TRAILERING APPF
The in-vehicle trailering app on the infotain-ment screen includes a variety of helpful func-tions when towing a trailer, including hitch-ing and setup checklists, trailer tire pressure monitoringF, trailer light testing, customized trailer profiles, trailer theft detection (requires an active OnStar service planF) and more.
INTEGRATED TRAILER BRAKE CONTROL
(ITBC)F
The ITBC system can be used to adjust the amount of power output, or Trailer Gain, avail-able to the trailer brakes. The control panel is located on the left side of the instrument panel. ITBC information is displayed on the ITBC page on the Driver Information Center.
Squeeze the control together (right side does not move) to manually apply the trailer brakes.
Adjust the Trailer Gain by pressing the +/– adjustment buttons on the control panel. See Driving and Operating in your Owner’s Manual.
F Optional equipment
TRACTION CONTROL
The Traction Control system limits wheelspin in difficult driving conditions. The system turns 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 button on the left side of the instrument panel to turn Traction Control off or on again. See Driving and Operating in your Owner’s Manual.
TRAILERINGF
TIRE PRESSURE MONITORING SYSTEM
The Low Tire Pressure warning light on the instrument cluster illuminates when one or more of the vehicle’s tires is significantly underinflated. Fill the tires to the proper tire pressures listed on the Tire and Loading Information label, located on the driver’s door opening below the door latch. Current tire pressures can be viewed on the Driver Information Center.
The Tire Fill Alert provides visual and audible alerts when inflating a tire to the recom-mended air pressure (excluding the spare tire). With the vehicle On, the horn sounds and the turn signals change from flashing to solid when the recommended pressure is reached.See Vehicle Care in your Owner’s Manual.
