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.
Seat pulsing alerts or audible 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 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 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 the system on or off, go to Settings > Vehicle > Collision/Detection Systems > Lane Change Alert.
Forward Collision AlertF — 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 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. This is also the Adaptive Cruise ControlF following gap setting.
Forward Automatic BrakingF — In potential front-end imminent collision situations with detect-ed vehicles, the brakes may be applied, if you have not already done so, to help reduce dam-age or avoid collisions at very low speeds.
To set the Forward Collision Alert and Forward Automatic Braking systems to Alert and Brake, Alert, or Off, go to Settings > Vehicle > Collision/Detection Systems > 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 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
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.
Press the Lane Keep Assist button (A) to turn the system on or off.
Front Pedestrian BrakingF — During daytime driving at speeds of 5–50 mph, 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 rapidly, a red alert flashes on the windshield and the Safety Alert Seat pulses or rapid beeps sound (if select-ed). The system may prepare the brakes or automatically brake the vehicle, if you have not already done so.
To set the system to Alert and Brake, Alert, or Off, go to Settings > Vehicle > Collision/Detection Systems > Front Pedestrian Detection.
