CROSS TRAFFIC ALERT (If Equipped)
WARNING: Never use the CrossTraffic Alert system as a replacement forusing the interior and exterior mirrors andlooking over your shoulder before backingout of a parking space. Cross Traffic Alertis not a replacement for careful driving.
Cross Traffic Alert is designed to warn youof vehicles approaching from the sides whenthe transmission is in reverse (R).
Using the System
Cross Traffic Alert turns on when you startthe engine and you shift into reverse (R).Once shifted out of reverse (R), Cross TrafficAlert turns off.
Note:Cross Traffic Alert only functions whileyour transmission is in reverse (R).
Cross Traffic Alert is designed to alert thedriver of certain collision risks. Coveragedecreases when the sensors are partially,mostly or fully obstructed. Reversing slowlyhelps increase the coverage area andeffectiveness.

In this first example, the left sensor is onlypartially obstructed; zone coverage to theright is nearly maximized.
Zone coverage also decreases when parkingat shallow angles. Here, the left sensor ismostly obstructed; zone coverage on thatside is severely limited.

System Lights, Messages and AudibleAlerts
The Cross Traffic Alert illuminates an amberalert indicator in the outside mirror on theside of your vehicle the approaching vehicleis coming from. Cross Traffic Alert alsosounds an audible alert and a messageappears in the information display indicatinga vehicle is coming from the right or left.Cross Traffic Alert works with the reversesensing system that sounds its own seriesof tones. See Rear Parking Aid (page 192).
The system uses radar sensors that arelocated behind the bumper fascia on eachside of your vehicle. Do not allow mud, snowor bumper stickers to obstruct these areas,this can cause degraded systemperformance. See Blind Spot InformationSystem (page 219). If the Blind SpotInformation System is blocked, Cross TrafficAlert is also blocked. A correspondingmessage appears in the information displayas soon as you shift the transmission intoreverse (R).
System Limitations
Cross Traffic Alert has its limitations;situations such as severe weather conditionsor debris build-up on the sensor area maylimit vehicle detection.
The system detects approaching vehiclesfrom up to 45 ft (14 m) away, thoughcoverage decreases when the sensors areblocked. Reversing slowly helps increase thecoverage area and effectiveness.
The following are other situations that maylimit the Cross Traffic Alert performance:
•Stationary or slow moving vehicles.
•Pedestrians or objects in the roadway.
•Oncoming vehicles in the same lame.
•Severe weather conditions.
•Debris build-up near or around thesensor(s).
•Small distance to the vehicle ahead.
•Adjacently parking vehicles or objectsobstructing the sensors.
•Approaching vehicles passing at speedsgreater than 15 mph (24 km/h).
•Driving in reverse faster than 3 mph(5 km/h).
•Backing out of an angled parking spot.

If the rear end of the vehicle is hit ordamaged, the radar sensing zone may bealtered causing missed or false collisionwarnings. See your authorized dealer to haveyour collision warning radar checked forproper coverage and operation.
False Alerts
Note:When towing a trailer, the sensors maydetect the trailer thus causing a false alert.It may be desirable to turn the Blind SpotInformation System off if the false alertsbecome annoying.
There may be certain instances when thereis a false alert by the Cross Traffic Alertsystem that illuminates the alert indicatorwith no vehicle in the coverage zone. Someamount of false alerts are normal; they aretemporary and self-correct.
System Errors
If Cross Traffic Alert senses a problem withthe left or right sensor a message will appearin the information display. See InformationMessages (page 112).
Switching the System Off and On
You can temporarily switch Cross Traffic Alertoff in the information display. SeeInformation Messages (page 112). When youswitch Cross Traffic Alert off, you will notreceive alerts and the information displaywill display a system off message.
Note:The Cross Traffic Alert switches onwhenever the ignition is switched on andready to provide appropriate alerts whenthe transmission is in reverse (R). CrossTraffic Alert will not remember the lastselected on or off setting.
You can also have Cross Traffic Alertswitched off permanently at an authorizeddealer. Once switched off permanently, thesystem can only be switched back on at anauthorized dealer.
STEERING
Electric Power Steering
WARNING: The electric powersteering system has diagnostic checks thatcontinuously monitor the system. If a faultis detected, a message displays in theinformation display. Stop your vehicle assoon as it is safe to do so. Switch theignition off. After at least 10 seconds,switch the ignition on and watch theinformation display for a steering systemwarning message. If a steering systemwarning message returns, have the systemchecked by an authorized dealer.
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 mayresult in loss of steering control.
Your vehicle has an electric power steeringsystem. There is no fluid reservoir. Nomaintenance is required.

Note:The collision warning system is activeat speeds above approximately 5 mph(8 km/h).
This system is designed to alert the driver ofcertain collision risks. A radar detects if yourvehicle is rapidly approaching anothervehicle traveling in the same direction asyours.
If it is, a red warning light illuminates and anaudible warning chime sounds.
The brake support system assists the driverin reducing the collision speed by chargingthe brakes. If the risk of collision furtherincreases after the warning light illuminates,the brake support prepares the brake systemfor rapid braking. This may be apparent tothe driver. The system does not automaticallyactivate the brakes but, if the brake pedal ispressed, full force braking is applied even ifthe brake pedal is lightly pressed.
Using the Collision Warning System
WARNING: The collision warningsystem’s brake support can only helpreduce the speed at which a collisionoccurs if the driver applies the vehicle’sbrakes. The brake pedal must be pressedjust like any typical braking situation.
The warning system sensitivity can beadjusted to one of three possible settings byusing the information display control. SeeGeneral Information (page 105).
Note:If collision warnings are perceived asbeing too frequent or disturbing then thewarning sensitivity can be reduced, thoughthe manufacturer recommends using thehighest sensitivity setting where possible.Setting lower sensitivity would lead to fewerand later system warnings. See GeneralInformation (page 105).

If a message regarding a blocked sensorappears in the information display, the radarsignals from the sensor have beenobstructed. The sensors are located behinda fascia cover near the driver side of thelower grille. When the sensors are
obstructed, a vehicle ahead cannot bedetected and the collision warning systemdoes not function. The following table listspossible causes and actions for this messagebeing displayed.
ActionCause
Clean the grille surface in front of the radar or remove the objectcausing the obstructionThe surface of the radar in the grille is dirty or obstructed in someway
Wait a short time. It may take several minutes for the radar to detectthat it is no longer obstructedThe surface of the radar in the grille is clean but the message remainsin the display
The collision warning system is temporarily disabled. Collision warningshould automatically reactivate a short time after the weather condi-tions improve
Heavy rain, spray, snow, or fog is interfering with the radar signals
The collision warning system is temporarily disabled. Collision warningshould automatically reactivate a short time after the weather condi-tions improve

System Limitations
WARNING: The collision warningsystem’s brake support can only helpreduce the speed at which a collisionoccurs if the driver applies the vehicle’sbrakes. The brake pedal must be pressedjust like any typical braking situation.
Due to the nature of radar technology, theremay be certain instances where vehicles donot provide a collision warning. Theseinclude:
•Stationary vehicles or vehicles movingbelow 6 mph (10 km/h).
•Pedestrians or objects in the roadway.
•Oncoming vehicles in the same lane.
•Severe weather conditions (see blockedsensor section).
•Debris build-up on the grille near theheadlamps (see blocked sensor section).
•Small distance to vehicle ahead.
•Steering wheel and pedal movementsare large (very active driving style).
If the front end of the vehicle is hit ordamaged, the radar sensing zone may bealtered causing missed or false collisionwarnings. See your authorized dealer to haveyour collision warning radar checked forproper coverage and operation.
