System Lights, Messages and AudibleAlerts
When the system detects a vehicle, anindicator illuminates in the exterior mirror onthe side the approaching vehicle is comingfrom. A tone sounds and a message appearsin the information display.
Note:In exceptional conditions, the systemcould alert you even when there is nothingin the detection zone, for example a vehiclepassing in the distance.
Blocked Sensors
The sensors are behind the rear bumper onboth sides of your vehicle.
Note:Keep the sensors free from snow, iceand large accumulations of dirt.
Note:Do not cover the sensors with bumperstickers, repair compound or other objects.
Note:Blocked sensors could affect systemperformance.
If the sensors are blocked, a message mayappear in the information display when youshift into reverse (R). See InformationMessages (page 116).
System Limitations
The system may not correctly operate whenany of the following occur:
•The sensors are blocked.
•Adjacently parked vehicles or objects areobstructing the sensors.
•Vehicles approach at speeds greaterthan 37 mph (60 km/h).
•The vehicle speed is greater than 7 mph(12 km/h).
•You reverse out of an angled parkingspace.
System Errors
If the system detects a fault a messagedisplays. See Information Messages (page116).

STEERING
Electric Power Steering
WARNING: The electric power steeringsystem has diagnostic checks thatcontinuously monitor the system. If a fault isdetected, a message displays in theinformation display. Stop your vehicle assoon as it is safe to do so. Switch the ignitionoff. After at least 10 seconds, switch theignition on and watch the information displayfor a steering system warning message. If asteering system warning message returns,have the system checked by an authorizeddealer.
WARNING: If the system detects anerror, you may not feel a difference in thesteering, however a serious condition mayexist. Obtain immediate service from anauthorized dealer, failure to do so may resultin loss of steering control.
Your vehicle has an electric power steeringsystem. There is no fluid reservoir. Nomaintenance is required.
If your vehicle loses electrical power whileyou are driving, electric power steeringassistance is lost. The steering system stilloperates and you can steer your vehiclemanually. Manually steering your vehiclerequires more effort.
Extreme continuous steering may increasethe effort required for you to steer yourvehicle. This increased effort preventsoverheating and permanent damage to thesteering system. You do not lose the abilityto steer your vehicle manually. Typicalsteering and driving maneuvers allow thesystem to cool and return to normaloperation.
Steering Tips
If the steering wanders or pulls, check for:
•Correct tire pressures.
•Uneven tire wear.
•Loose or worn suspension components.
•Loose or worn steering components.
•Improper vehicle alignment.

Note:A high crown in the road or highcrosswinds may also make the steeringseem to wander or pull.
Adaptive Learning
The electronic power steering systemadaptive learning helps correct roadirregularities and improves overall handlingand steering feel. It communicates with thebrake system to help operate advancedstability control and accident avoidancesystems. Additionally, whenever the batteryis disconnected or a new battery installed,you must drive your vehicle a short distancebefore the system relearns the strategy andreactivates all systems.
PRE-COLLISION ASSIST (If Equipped)
WARNING: You are responsible forcontrolling your vehicle at all times. Thesystem is designed to be an aid and doesnot relieve you of your responsibility to drivewith due care and attention. Failure to followthis instruction could result in the loss ofcontrol of your vehicle, personal injury ordeath.
WARNING: The system does not detectvehicles that are driving in a differentdirection, pedestrians at night, cyclists oranimals. Failure to take care may result inthe loss of control of your vehicle, seriouspersonal injury or death.
WARNING: The system does notoperate during hard acceleration or steering.Failure to take care may lead to a crash orpersonal injury.
WARNING: The system may fail oroperate with reduced function during coldand severe weather conditions. Snow, ice,rain, spray and fog can adversely affect thesystem. Keep the front camera and radar freeof snow and ice. Failure to take care mayresult in the loss of control of your vehicle,serious personal injury or death.
WARNING: In situations where thevehicle camera has limited detectioncapability, this may reduce systemperformance. These situations include butare not limited to direct or low sunlight,vehicles at night without tail lights,unconventional vehicle types, pedestrianswith complex backgrounds, runningpedestrians, partly obscured pedestrians, orpedestrians that the system cannotdistinguish from a group. Failure to take caremay result in the loss of control of yourvehicle, serious personal injury or death.

WARNING: The system cannot helpprevent all crashes. Do not rely on thissystem to replace driver judgment and theneed to maintain a safe distance and speed.
Using the Pre-Collision Assist System
The Pre-Collision Assist system is active atspeeds above approximately 3 mph (5 km/h)and pedestrian detection is active at speedsup to 50 mph (80 km/h).
If your vehicle is rapidly approaching anotherstationary vehicle, a vehicle traveling in thesame direction as yours, or a pedestrianwithin your driving path, the system isdesigned to provide three levels offunctionality:
1. Alert
2. Brake Support
3. Active Braking
Alert: When active, a flashing visual warningappears and an audible warning tonesounds.
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.
Active Braking: Active braking may activateif the system determines that a collision isimminent. The system may help the driverreduce impact damage or avoid the crashcompletely.
Note:If you perceive Pre-Collision Assistalerts as being too frequent or disturbing,then you can reduce the alert sensitivity,though the manufacturer recommends usingthe highest sensitivity setting where possible.Setting lower sensitivity would lead to fewerand later system warnings.
Distance Indication and Alert
Distance Indication and Alert is a functionthat provides a graphical indication of thetime gap to other preceding vehiclestraveling in the same direction. The DistanceIndication and Alert screen in the informationdisplay shows a graphic similar to the onethat follows.
If the time gap to a preceding vehicle issmall, a red visual indication displays.
