DRIVER ASSISTANCE SYSTEMSF
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. 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.

detected cross-traffic approaching in either direction by displaying a red triangle with

To turn on or off, go to Settings > Vehicle > Collision/Detection Systems > Rear Cross
Traffic Alert.
