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

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 and is amber when following a vehicl e ahead much too closely. When approaching a vehicle directly ahead too rapidly, a red alert flashes on the windshield

following distance to the vehicle ahead is
indicated in seconds under the Info menu

AUTOMATIC EMERGENCY BRAKING – In
detected potential imminent collision situ -
ations 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.
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
FRONT PEDESTRIAN BRAKING – During daytime driving, the system can detect pedes -
trians 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 enhance driver braking or automatically apply hard emergency braking, if you have not already done so.
To set to Alert and Brake, Alert, or Off, go to Settings > Vehicle > Collision/Detection
Systems > Front Pedestrian Detection.
LANE CHANGE ALERT WITH SIDE BLIND ZONE ALERT – While driving, the system displays a warning symbol on the left or right side mirror when a moving vehicle
is detected rapidly approaching or in a side blind zone. 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.
See Driving and Operating in your Owner’s Manual.

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. In order to use this system safely, 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 instrument panel.
FRONT AND REAR PARK ASSIST – During
low-speed parking maneuvers, the system
provides “distance to closest object” infor -

sounds (if selected). When an object is very
close, the Safety Alert Seat pulses or a
continuous beep sounds (if selected).
To turn on or off, press the Park Assist button on the instrument panel.
REAR CROSS TRAFFIC ALERT – When the vehicle is in Reverse, the system warns of
detected cross-traffic approaching in either direction by displaying a red triangle with
directional arrow alert on the infotainment screen and pulsing the left or right side of
the Safety Alert Seat or sounding beeps (if selected).
To turn on or off, go to Settings > Vehicle > Collision/Detection Systems > Rear Cross
Traffic Alert.
