HOW DOES STABILITY
CONTROL WORK
WARNING: Vehicle modificationsinvolving braking system, aftermarketroof racks, suspension, steering system,tire construction and wheel and tire sizemay change the handling characteristicsof your vehicle and may adversely affectthe performance of the electronicstability control system. In addition,installing any stereo speakers mayinterfere with and adversely affect theelectronic stability control system.Reducing the effectiveness of theelectronic stability control system couldlead to an increased risk of loss of vehiclecontrol, vehicle rollover, personal injuryand death.
WARNING: Remember that evenadvanced technology cannot defy thelaws of physics. It's always possible tolose control of a vehicle due toinappropriate driver input for theconditions. Aggressive driving on anyroad condition can cause you to losecontrol of your vehicle increasing the riskof personal injury or property damage.Activation of the electronic stabilitycontrol system is an indication that atleast some of the tires have exceededtheir ability to grip the road; this couldreduce the operator's ability to controlthe vehicle potentially resulting in a lossof vehicle control, vehicle rollover,personal injury and death.
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. Failureto follow this instruction could result inthe loss of control of your vehicle,personal injury or death.
If a driving condition activates either thestability control or traction control you mayexperience the following conditions:
•The stability and traction control lightflashes.
•Your vehicle slows down.
•Reduced engine power.
The stability control system has severalfeatures built into it to help you maintaincontrol of your vehicle:
Electronic Stability Control
Electronic stability control enhances yourvehicle’s ability to prevent skids or lateralslides by applying brakes to one or moreof the wheels individually and, if necessary,reducing engine power.
Roll Stability Control
Roll stability control enhances yourvehicle’s ability to prevent rollovers bydetecting your vehicle’s roll motion andthe rate at which it changes by applyingthe brakes to one or more wheelsindividually.
Curve Control
Curve control enhances your vehicle’sability to follow the road when corneringseverely or avoiding objects in the roadway.Curve control operates by reducing enginepower and, if necessary, applying brakesto one or more of the wheels individually.

•Your vehicle slows down.
•Reduced engine power.
•A vibration in the brake pedal.
•The brake pedal is stiffer than usual.
•If the driving condition is severe andyour foot is not on the brake, the brakepedal may move as the system applieshigher brake force.

WHAT IS TRAIL TURN ASSIST
Trail turn assist can reduce the turningradius of your vehicle by applying thebrakes to the inside rear wheel inlow-speed, high steering-angle maneuvers.
TRAIL TURN ASSIST
PRECAUTIONS
Note:Do not use trail turn assist on dry,hard surfaced roads. Doing so can produceexcessive noise, increase tire wear and maydamage drive line, or braking components.Trail turn assist is only intended for slippery,or loose surfaces.
You may hear noise from the anti-lockbrake system while trail turn assist isactive. This is normal operation.
TRAIL TURN ASSIST
LIMITATIONS
You can only use trail turn assist when thesystem is in four-wheel drive high (4H), orfour-wheel drive low (4L) mode.
You cannot use trail turn assist with therear differential engaged. If the systemdetects that the rear differential hasrecently been engaged, it may not activatetrail turn assist until it can confirm that therear differential is disengaged.
If the vehicle’s rear differential is engagedwhen pressing the trail turn assist button,the rear differential will attempt todisengage to allow for trail turn assistoperation.
SWITCHING TRAIL TURN
ASSIST ON AND OFF
Bronco Off-Road Features
While in four-wheel drive high (4H) orfour-wheel drive low (4L), press the trailturn assist button to turn the feature on.trail turn assist will be on at this time butwill not activate until:
•Vehicle speed is less than 12 mph(19.3 km/h).
•Rear differential is fully unlocked.
•Steering wheel is almost fully turnedto the left or right.
You can turn off trail turn assist by doingany of the following:
•Pressing the trail turn assist buttonagain.
•Selecting a two-wheel drive high (2H),or four-wheel drive auto (4A).
•Turning on the rear locking differential.
TRAIL TURN ASSIST
INDICATORS
When trail turn assist is on, oneof these two indicators will bedisplayed, depending on thedirection of the vehicle’s lastturn. When the feature is on butnot in use, the indicator light willbe gray. When the feature is active theindicator light will be green.

WHAT IS HILL DESCENT
CONTROL
Hill descent control allows the driver to setand maintain vehicle speed whiledescending steep slopes in various surfaceconditions.
HOW DOES HILL DESCENT
CONTROL WORK
Hill descent control can maintain vehiclespeeds on downhill slopes between2–20 mph (3–32 km/h). Above 20 mph(32 km/h), the system remains on but thedescent speed cannot be set ormaintained.
Note:The system does not function below2 mph (3 km/h).
The system requires a cool down intervalafter a period of sustained use. Hill descentcontrol provides a warning in the messagecenter and a tone sounds when the systemis about to disengage for cooling. At thistime, manually apply the brakes as neededto maintain descent speed.
Note:The amount of time that the systemcan remain active before cooling varies withconditions.
HILL DESCENT CONTROL
PRECAUTIONS
WARNING: The system does notcontrol speed in low traction conditionsor extremely steep slopes. The systemis designed to be an aid and does notrelieve you of your responsibility to drivewith due care and attention. Failure tofollow this instruction could result inpersonal injury.
WARNING: The system does notreplace the parking brake. When youleave your vehicle, always apply theparking brake.

ADAPTIVE CRUISE CONTROL
LIMITATIONS
Sensor Limitations
WARNING: On rare occasions,detection issues can occur due to theroad infrastructures, for example bridges,tunnels and safety barriers. In thesecases, the system may brake late orunexpectedly. At all times, you areresponsible for controlling your vehicle,supervising the system and intervening,if required.
WARNING: If the systemmalfunctions, have your vehicle checkedas soon as possible.
WARNING: Large contrasts inoutside lighting can limit sensorperformance.
WARNING: The system only warnsof vehicles detected by the radar sensor.In some cases there may be no warningor a delayed warning. Apply the brakeswhen necessary. Failure to follow thisinstruction could result in personal injuryor death.
WARNING: The system may notdetect stationary or slow movingvehicles below 6 mph (10 km/h).
WARNING: The system does notdetect pedestrians or objects in the road.
WARNING: The system does notdetect oncoming vehicles in the samelane.
WARNING: The system may notoperate properly if the sensor is blocked.Keep the windshield free fromobstruction.
WARNING: The sensor mayincorrectly track lane markings as otherstructures or objects. This can result ina false or missed warning.
The camera is mounted on the windshieldbehind the interior mirror.
The radar sensor is in the lower grille.
Note:You cannot see the sensor. It isbehind a fascia panel.

Note:Keep the front of your vehicle free ofdirt, metal badges or objects. Vehicle frontprotectors, aftermarket lights, additionalpaint or plastic coatings could also degradesensor performance.
A message displays if something obstructsthe camera or the sensor. When somethingblocks the sensor, the system cannotdetect a vehicle ahead and does notfunction. See Adaptive Cruise Control –Information Messages (page 258).
The radar sensor has a limited field ofview. It may not detect vehicles at all ordetect a vehicle later than expected insome situations. The lead vehicle imagedoes not illuminate if the system does notdetect a vehicle in front of you.
Detection issues can occur:
When driving on a different linethan the vehicle in front.A
With vehicles that edge into yourlane. The system can only detectthese vehicles once they movefully into your lane.
B
There may be issues with thedetection of vehicles in frontwhen driving into and coming outof a bend or curve in the road.
C
In these cases, the system may brake lateor unexpectedly.
If something hits the front end of yourvehicle or damage occurs, theradar-sensing zone could change. Thiscould result in a missed or false vehicledetection.
