DRIVER ASSISTANCE SYSTEMS
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 trac, 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/o or to change system settings,
go to Settings > Vehicle > Collision/Detection Systems on the infotainment screen.
SAFETY ALERT SEATF – The driver’s seat pulses — left side, right side or both sides —
to alert the driver of the direction of potential hazards. Audible alerts may be selected
instead.
FORWARD COLLISION ALERT – The Vehicle Ahead Indicator is green when a vehicle
that you’re following is detected and is amber when you’re following a vehicle ahead
much too closely. When approaching a vehicle directly ahead too rapidly, a red alert
ashes 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.
FOLLOWING DISTANCE INDICATOR – The following distance to the vehicle ahead is
indicated in seconds under the Info menu on the Driver Information Center. If no vehicle
is detected ahead, dashes are displayed.
AUTOMATIC EMERGENCY BRAKING – The system works with Forward Collision Alert
to help you avoid or reduce the severity of front-end collisions with a detected vehicle
you’re following. The system works at speeds below 50 mph. Camera technology is used
to automatically provide hard emergency braking or enhance the driver’s hard braking.
FRONT PEDESTRIAN BRAKING – During daytime driving below 50 mph, the system can
detect pedestrians directly ahead and displays an amber indicator. When approach-
ing a detected pedestrian too quickly, a red alert ashes on the windshield and the
Safety Alert Seat pulses or rapid beeps sound (if selected). The system may automati-
cally provide hard emergency braking or enhance the driver’s hard braking. Nighttime
and low-visibility performance are limited.
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 ashes red and the Safety Alert Seat pulses or rapid beeps sound
(if selected). Nighttime and low-visibility performance are limited.
LANE CHANGE ALERT WITH SIDE BLIND ZONE ALERTF/TRAILER 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 that side
blind zone, including the extended blind zone along the side of a trailer.* The warning
symbol ashes if a turn signal is activated when a vehicle has been detected on the
same side.
See Driving and Operating in your Owner’s Manual.
F Optional equipment *Not compatible with all trailers. Some equipment shown may not be included in your vehicle.

15
DRIVER ASSISTANCE SYSTEMS
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, the system may assist by gently turning the steering wheel to help prevent
lane departure and displays an amber . If active driver steering is not detected,
the amber may ash 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
system does not continuously steer the vehicle; the driver needs to steer and be in
complete control of the vehicle. Alerts do not occur when using the turn signal in the
lane departure direction or intentional lane departure is detected.
To turn on or o, press the
Lane Keep Assist button on the instrument panel.
FRONT AND REAR PARK ASSISTF – During
low-speed parking maneuvers, the system
provides “distance to closest object” infor-
mation on the Driver Information Center

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 o, press the Park
Assist button on the instrument panel.
REAR CROSS TRAFFIC BRAKINGF– When in Reverse, the system warns of detected
cross trac approaching in either direction and provides alerts and hard emergency
braking to help reduce the severity or help avoid collisions at very low speeds.
