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 important feature limitations and information.
SAFET Y 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 Systems > Alert Type.
FORWARD COLLISION ALERT – The Vehicle Ahead Indicator is green when a vehicle is detected ahead that you’re following 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 rapid beeps sound or the Safety Alert SeatF pulses (if selected).
Press the Forward 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.
FOLLOWING DISTANCE INDICATOR – The following distance to the vehicle ahead is indicat-ed in seconds under the Info menu on the Driver Information Center. If no vehicle is detected ahead, dashes are displayed.
AUTOMATIC EMERGENCY BRAKING – In detected potential imminent collision situations with vehicles being followed directly ahead, the system can provide alerts and enhance driver hard 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.
L ANE KEEP ASSIST WITH L ANE 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 beeps may sound or the Safety Alert SeatF 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.
FRONT PEDESTRIAN BR AKING – During daytime driving, the system can detect
pedestrians directly ahead and displays an amber indicator. When approaching a detected pedestrian too quickly, a red alert flashes on the windshield and rapid beeps sound or the Safety Alert SeatF 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 to Alert and Brake, Alert, or Off, go to Settings > Vehicle > Collision/Detection Systems > Front Pedestrian Detection.
L ANE 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 on or off, go to Settings > Vehicle > Collision/Detection Systems > Lane Change Alert.
