DRIVER ASSISTANCE SYSTEMSF
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 SEAT – 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 Systems > Alert Type.
LANE CHANGE ALERT WITH SIDE BLIND ZONE ALERT – While driving, the system dis-plays a warning symbol on the left or right side mirror when a vehicle is detected in that side blind zone area or rapidly approaching 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.
FORWARD COLLISION ALERT – The Vehicle Ahead Indicator is green 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 wind-shield 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.
FOLLOWING DISTANCE INDICATOR – The following distance to the vehicle ahead is indi-cated in seconds under the Info menu on the Driver Information Center. If no vehicle is detected ahead, dashes are displayed.
LOW-SPEED FORWARD AUTOMATIC BRAKING – In potential front-end imminent colli-sion situations with detected vehicles, the brakes may be applied, if you haven’t already done so, to help reduce damage or avoid collisions at very low speeds.
To set Forward Automatic Braking and Forward Collision Alert to Alert and Brake, Alert, or Off, go to Settings > Vehicle > Collision/Detection Systems > Forward Collision System.
LANE KEEP ASSIST WITH LANE DEPARTURE WARNING – 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 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 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.
See Driving and Operating in your Owner’s Manual.

REAR VISION CAMERA/SURROUND VISIONF
FRONT PEDESTRIAN BRAKING – During daytime driving, the system detects pedestri-ans directly ahead up to a distance of approximately 131 ft. 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.
To set to Alert and Brake, Alert, or Off, go to Settings > Vehicle > Collision/Detection Systems > Front Pedestrian Detection.
FRONT AND REAR 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 ALERT – 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 pulsing the left or right side of the Safety Alert Seat or sounding beeps (if selected).
To turn only Rear Cross Traffic Alert on or off, go to Settings > Vehicle > Collision/Detection Systems > Rear Cross Traffic Alert.
To turn Front and Rear Park Assist and Rear Cross Traffic Alert on or off, press the Park Assist button on the center console.

HILL DESCENT CONTROLF (X31)
INTEGRATED TRAILER BRAKE CONTROL (ITBC)F
Hill Descent Control sets and maintains vehicle speed from 1–14 mph while descending a steep incline in a forward or reverse gear.
1. Press the Hill Descent Control button on the center of the instrument panel. Vehicle speed must be below 31 mph to enable the system. The Hill Descent Control symbol will illuminate on the instrument cluster.
2. Increase or decrease speed by applying the accelerator or brake pedal or use the Cruise Control +/– buttons on the steering wheel. The adjusted speed becomes the new set speed. The symbol flashes when the system is actively applying the brakes to maintain vehicle speed.
See Driving and Operating in your Owner’s Manual.
The ITBC system can be used to adjust the amount of power output, or Trailer Gain, available to the trailer brakes. The control panel is located on the left side of the instrument panel. ITBC information is dis-played on the Driver Information Center.
Squeeze the levers together on the
control panel (left lever does not move) to manually apply the trailer brakes.
Adjust the Trailer Gain by pressing the +/– adjustment buttons on the control panel.
The trailer app will remember your Trailer Gain adjustments for each trailer profile.
See Driving and Operating in your Owner’s Manual.
TIRE PRESSURE MONITOR
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 below the driver’s door latch. Current tire pressures can be viewed on the Driver Information Center.
The Tire Fill Alert provides visual and audible alerts to help when inflating a tire to the recommended tire pressure (does not apply to spare tire). When the recommended pressure is reached, the horn sounds and the turn signals change from flashing to solid.
