ACTIVEGLIDE™ ALERTS
When ActiveGlide is providing hands-ondriving or transitioning to hands-on drivingfrom hands-free driving and detects nosteering activity for a certain period of time,the system alerts you with a message in theinstrument cluster to put your hands on thesteering wheel. After the first alert, thesystem alerts you with a message in theinstrument cluster and an audible warning.
When ActiveGlide is providing hands-on orhands-free driving and detects you are notlooking at the road for a certain period oftime, the system alerts you to return youreyes to the road. Depending on where youare looking, the alert can be a message inthe instrument cluster and an audiblewarning.
If you do not react to the warnings,ActiveGlide cancels, quickly activates andreleases the brakes, and slows your vehicledown to low speeds while maintainingsteering control.
If your vehicle slows down and you resumecontrol, a message appears to prompt youto press the accelerator pedal to allow thesystem to resume.
Note:If the system detects repeatedinactivity, it disables until the next key cycle.

CANCELLATION
When an external condition cancelsActiveGlide, for example, no lane markingsavailable, a tone sounds and a messageappears in the instrument cluster.
If your vehicle starts to slow down,you must take control of steeringand press and release the buttonto reactivate ActiveGlide.
System cancellation can also occur if:
•The lane becomes too narrow.
•The system cannot detect valid lanemarkings.
•Lane markings cross.
•Your eyes are not on the road or yourhands are not the steering wheel.
If you have your hands on the steering wheeland your eyes are on the road when thefeature is active and a cancellation occurs,the system sounds a tone and displays acancelled graphic in the instrument cluster.
If you are not paying attention to the road oryour hands are not on the steering wheeland a cancellation occurs, the systemdisplays a message and a tone sounds untilyou resume control. If you do not resumecontrol in time, ActiveGlide quickly activatesand releases the brakes, and slows yourvehicle down to low speeds whilemaintaining steering control. If your vehicleslows down and you resume control, amessage appears to prompt you to press theaccelerator pedal to allow the system toresume.
Note:The system disables until the next keycycle if it detects repeated inactivity.

WHAT IS PRE-COLLISION ASSIST
Pre-collision assist detects and warns ofapproaching hazards in the roadway. Thesystem provides multiple levels of assistanceto help avoid a collision if your vehicle israpidly approaching another stationaryvehicle, a vehicle traveling in the samedirection as yours, or a pedestrian or cyclistwithin your driving path.
HOW DOES PRE-COLLISION
ASSIST WORK
The system warns the driver of potentialhazards by providing three levels ofassistance.
If your vehicle is rapidly approachingpotential hazards the system provides thefollowing levels of functionality:
1.Alert.
2.Brake Support.
3.Automatic Emergency Braking.
Alert: When active, a flashingvisual warning appears and anaudible warning tone sounds.
Brake Support: The system is designed tohelp reduce the impact speed by preparingthe brakes for rapid braking. The systemdoes not automatically apply the brakes. Ifyou press the brake pedal, the system couldapply additional braking up to maximumbraking force, even if you lightly press thebrake pedal.
Automatic Emergency Braking: Automaticemergency braking may activate if thesystem determines that a collision isimminent.
Note:If you perceive the pre-collision assistalerts as being too frequent or disturbing,then you can reduce the alert sensitivity.Setting the low sensitivity would result infewer and later warnings of a potentialforward collision. The manufacturerrecommends using the high sensitivitysetting where possible.
Note:Automatic emergency brakingperformance is not affected by the sensitivitysetting.
Each system has various levels of detectioncapabilities. See Pre-Collision AssistLimitations (page 322).
PRE-COLLISION ASSIST
PRECAUTIONS
WARNING: You are responsible forcontrolling your vehicle at all times. Thesystem is designed to be an aid and doesnot relieve you of your responsibility todrive with due care and attention.
