DRIVER ASSISTANCE SYSTEMSF
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.
SAFETY ALERT SEAT – The driver’s seat pulses — left side, right side or simultan\
eously — to alert the driver of the direction of potential hazards.
Audible alerts or seat pulsing alerts may be selected. To change the ale\
rt settings, go to Settings > Vehicle > Collision/Detection Systems > Alert Type.
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.
FORWARD COLLISION ALERT – The Vehicle Ahead Indicator is green when a vehicle is detected and is amber when following a vehicle ahead much too closely. W\
hen approach-ing a vehicle directly ahead too rapidly, a red alert flashes on the w\
indshield 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 vehi-cle is detected ahead, dashes are displayed.
AUTOMATIC EMERGENCY BRAKING – In detected potential imminent collision
situations with vehicles directly ahead, the system can provide alerts and enhance driver braking or automatically apply hard emergency braking, if you hav\
e not already done so, to help reduce the severity or help avoid collisions at very lo\
w 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.
See Driving and Operating in your Owner’s Manual.
