PRINCIPLE OF OPERATION
The traction control system helps avoiddrive wheel spin and loss of traction.
If your vehicle begins to slide, the systemapplies the brakes to individual wheelsand, when needed, reduces engine powerat the same time. If the wheels spin whenaccelerating on slippery or loose surfaces,the system reduces engine power in orderto increase traction.
USING TRACTION CONTROL
WARNING
The stability and traction controllight illuminates steadily if thesystem detects a failure. Make sureyou did not manually disable the tractioncontrol system using the switch. If thestability control and traction control lightis still illuminating steadily, have thesystem serviced by an authorized dealerimmediately. Operating your vehicle withtraction control disabled could lead to anincreased risk of loss of vehicle control,vehicle rollover, personal injury and death.
The system automatically turns on eachtime you switch the ignition on.
If your vehicle is stuck in mud or snow,switching traction control off may bebeneficial as this allows the wheels to spin.
Note:When you switch traction control off,stability control remains fully active.
Switching the System Off
The switch for the stability and tractioncontrol system is on the instrument panel.
When you switch the system off, amessage and an illuminated icon appearon the instrument cluster.
Use the switch again to return the tractioncontrol system to normal operation.
Your vehicle may have MyKey restrictionsregarding this feature. See Principle ofOperation (page 46).

PRINCIPLE OF OPERATION
WARNINGS
Vehicle modifications involvingbraking system, aftermarket roofracks, suspension, steering system,tire construction and wheel and tire sizemay change the handling characteristicsof your vehicle and may adversely affectthe performance of the electronic stabilitycontrol system. In addition, installing anystereo loudspeakers may interfere withand adversely affect the electronic stabilitycontrol system. Install any aftermarketstereo loudspeaker as far as possible fromthe front center console, the tunnel, andthe front seats in order to minimize the riskof interfering with the electronic stabilitycontrol sensors. Reducing theeffectiveness of the electronic stabilitycontrol system could lead to an increasedrisk of loss of vehicle control, vehiclerollover, personal injury and death.
Remember that even advancedtechnology cannot defy the laws ofphysics. It’s always possible to losecontrol of a vehicle due to inappropriatedriver input for the conditions. Aggressivedriving on any road condition can causeyou to lose control of your vehicleincreasing the risk of personal injury orproperty damage. Activation of theelectronic stability control system is anindication that at least some of the tireshave exceeded their ability to grip the road;this could reduce the operator’s ability tocontrol the vehicle potentially resulting ina loss of vehicle control, vehicle rollover,personal injury and death. If your electronicstability control system activates, SLOWDOWN.
The system automatically turns on eachtime you switch the ignition on.
If a driving condition activates either thestability control or the traction controlsystem you may experience the followingconditions:
•The stability and traction control lightflashes.
•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 systemsapplies higher brake forces.
The stability control system has severalfeatures built into it to help you maintaincontrol of your vehicle:
Electronic Stability Control
The system enhances your vehicle’s abilityto prevent skids or lateral slides byapplying brakes to one or more of thewheels individually and, if necessary,reducing engine power.
Roll Stability Control
The system enhances your vehicle’s abilityto prevent rollovers by detecting yourvehicle’s roll motion and the rate at whichit changes by applying the brakes to oneor more wheels individually.
Traction Control
The system enhances your vehicle’s abilityto maintain traction of the wheels bydetecting and controlling wheel spin. SeeUsing Traction Control (page 175).

BLIND SPOT INFORMATION
SYSTEM
WARNING
To help avoid injuries, NEVER use theBlind Spot Information System as areplacement for using the interiorand exterior mirrors or looking over yourshoulder before changing lanes. The BlindSpot Information System is not areplacement for careful driving.
The Blind Spot Information System isdesigned to aid you in detecting vehiclesthat may have entered the blind spot zone(A). The detection area is on both sides ofyour vehicle, extending rearward from theexterior mirrors to approximately 13 ft(4 m) beyond the bumper. The system isdesigned to alert you if certain vehiclesenter the blind spot zone while driving.
Note:The Blind Spot Information Systemdoes not prevent contact with other vehiclesor objects; nor detect parked vehicles,people, animals or infrastructure (fences,guardrails, trees). It’s only designed to alertyou to vehicles in the blind spot zones.
Note:When a vehicle passes quicklythrough the blind spot zone, typically fewerthan two seconds, the system does nottrigger.
Using the System
The Blind Spot Information System turnson when you start the engine and you driveyour vehicle forward above 5 mph(8 km/h).
For automatic transmissions, the BlindSpot Information System remains on whilethe transmission is in drive (D). If shiftedinto reverse (R) or park (P) the Blind SpotInformation System turns off. Once shiftedback into drive (D), the Blind SpotInformation System turns back on whenyou drive your vehicle above 5 mph(8 km/h).
For manual transmissions, the Blind SpotInformation System is on for all gearsexcept the reverse (R).
Note:The Blind Spot Information Systemdoes not function in reverse (R) or park (P).

If the system detects a degradedperformance condition, a message warningof a blocked sensor will appear in theinformation display. Also the BLIS alertindicators will remain ON and BLIS will nolonger provide any vehicle warnings. Youcan clear the information display warningbut the alert indicators will remainilluminated.
A "blocked" condition can be cleared intwo ways:
•After the blockage in front of thesensors is removed or therainfall/snowfall rate decreases orstops, drive for a few minutes in trafficto allow the sensors to detect passingvehicles.
•By cycling the ignition from ON to OFFand then back ON.
Note:If your vehicle has a tow bar with afactory equipped trailer tow module and itis towing a trailer, the sensors willautomatically turn the Blind SpotInformation System off. If your vehicle hasa tow bar but no factory equipped trailertow module, it is recommended to turn theBlind Spot Information System offmanually. Operating the Blind SpotInformation System with a trailer attachedwill cause poor system performance.
System Errors
If the system senses a problem with theleft or right sensor, the telltale willilluminate and a message will appear inthe information display. See InformationMessages (page 103).
Switching the System Off and On
You can temporarily switch the Blind SpotInformation System off in the informationdisplay. See General Information (page92). When the Blind Spot InformationSystem switches off, you will not receivealerts and the information display showsa system off message. The telltale in thecluster also illuminates. When you switchthe Blind Spot Information System on oroff, the alert indicators flash twice.
Note:The Blind Spot Information Systemremembers the last selected on or offsetting.
You can also have the Blind SpotInformation System switched offpermanently at an authorized dealer. Onceswitched off permanently, the system canonly be switched back on at an authorizeddealer.
CROSS TRAFFIC ALERT
WARNING
To help avoid personal injury, NEVERuse the Cross Traffic Alert system asa replacement for using the interiorand exterior mirrors and looking over yourshoulder before backing out of a parkingspace. Cross Traffic Alert is not areplacement for careful driving.
Cross Traffic Alert is designed to warn youof vehicles approaching from the sideswhen the 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), CrossTraffic Alert turns off.
Note:Cross Traffic Alert only functionswhile your transmission is in reverse (R).

Modes:
•Comfort – Provides a more relaxeddriving experience, maximizing comfort.Your steering effort decreases and thesuspension movement is more fluid.Comfort mode is ideal when you desireenhanced traveling comfort.
•Normal – Delivers a balancedcombination of comfortable, controlledride and confident handling. This modeprovides an engaging drive experienceand a direct connection to the roadwithout sacrificing any of thecomposure demanded from yourvehicle.
•Sport – Provides a sportier drivingexperience. The suspension stiffens,with an emphasis on handling andcontrol. The engine responds moredirectly to your inputs. Sport mode isideal for use during more spiriteddriving.
Adaptive Steering
You can configure which of the modes areactive from the main menu on theinformation display. See GeneralInformation (page 92).
Modes:
•Normal – Default factory setting.
•Sport – Slightly higher effort requiredfor steering with more road force feltthrough the steering wheel.
Note:The Drive Control has diagnosticchecks that continuously monitor thesystem to ensure proper operation. Certaintypes of system errors will gray out themode selections within the informationdisplay, preventing you from changing stateswhen the gear position is changed. Othertypes of errors will produce a temporarymessage that states a malfunction. If eithercondition persists for multiple key cycles,have your vehicle checked by an authorizeddealer.
SELF-LEVELING SUSPENSION
The self-leveling suspension system isdesigned to improve ride, handling andgeneral vehicle performance during:
•Certain road conditions
•Steering maneuvers
•Braking
•Acceleration
•Towing
This system keeps the rear of your vehicleat a constant level through a hydraulicpump inside each rear shock. Dependingon the payload or road surface conditionsit will take approximately 2 mi (3.2 km) forthe leveling to complete.
If the loaded vehicle is not moved forapproximately 12 hours, the leveling systemmay bleed down to a lower height. Thiscan be especially apparent if a trailer is leftattached to the parked vehicle for longperiods of time. You must drive your vehiclein order to re-level the suspension.
If a self-equalizing hitch is used, yourvehicle should be driven approximately2 mi (3.2 km) with the trailer prior toadjusting (leveling) the hitch.

TOWING A TRAILER
WARNINGS
Do not exceed the GVWR orthe GAWR specified on thecertification label.
Towing trailers beyond themaximum recommendedgross trailer weight exceeds thelimit of the vehicle and couldresult in engine damage,transmission damage, structuraldamage, loss of vehicle control,vehicle rollover and personalinjury.
Your vehicle may have electricalitems, such as fuses or relays,related to towing. See the Fuseschapter.
Your vehicle's load capacitydesignation is by weight, not byvolume, so you cannot necessarilyuse all available space whenloading a vehicle or trailer.
Towing a trailer places an extraload on your vehicle's engine,transmission, axle, brakes, tiresand suspension. Inspect thesecomponents periodically during,and after, any towing operation.
Load Placement
To help minimize how trailermovement affects your vehiclewhen driving:
•Load the heaviest items closestto the trailer floor.
•Load the heaviest itemscentered between the left andright side trailer tires.
•Load the heaviest items abovethe trailer axles or just slightlyforward toward the trailertongue. Do not allow the finaltrailer tongue weight to goabove or below 10-15% of theloaded trailer weight.
•Select a tow bar with thecorrect rise or drop. When boththe loaded vehicle and trailerare connected, the trailer frameshould be level, or slightlyangled down toward yourvehicle, when viewed from theside.
When driving with a trailer orpayload, a slight takeoff vibrationor shudder may be present due tothe increased payload weight.Additional information regardingproper trailer loading and settingyour vehicle up for towing islocated in another chapter of thismanual. See Load Limit (page198).
You can also find information inthe RV & Trailer Towing Guideavailable at your authorizeddealer, or online.

TRAILER SWAY CONTROL
WARNING
Turning off trailer sway controlincreases the risk of loss of vehiclecontrol, serious injury or death. Forddoes not recommend disabling this featureexcept in situations where speed reductionmay be detrimental (such as hill climbing),the driver has significant trailer towingexperience, and can control trailer swayand maintain safe operation.
Note:This feature does not prevent trailersway, but reduces it once it begins.
Note:This feature cannot stop all trailersfrom swaying.
Note:In some cases, if vehicle speed is toohigh, the system may activate multipletimes, gradually reducing vehicle speed.
This feature applies your vehicle brakes atindividual wheels and, if necessary, reducesengine power. If the trailer begins to sway,the stability control light flashes and themessage TRAILER SWAY REDUCESPEED appears in the information display.The first thing to do is slow your vehicledown, then pull safely to the side of theroad and check for proper tongue load andtrailer load distribution. See LoadCarrying (page 196).
RECOMMENDED TOWING
WEIGHTS
Note:Do not exceed the trailer weight foryour vehicle configuration listed in the chartbelow.
Note:Make sure to take into considerationtrailer frontal area. Do not exceed 36.5 feet²(3.39 meters²) if your vehicle is equippedwith the standard towing package, or 60feet² (5.57 meters²) if your vehicle isequipped with the optional heavy dutypackage.
Note:Exceeding this limitation maysignificantly reduce the performance of yourtowing vehicle. Selecting a trailer with a lowaerodynamic drag and rounded front designhelps optimize performance and fueleconomy.
Note:For high altitude operation, reducethe gross combined weight by 2% per 1000feet (300 meters) starting at the 1000 foot(300 meter) elevation point.
Note:Certain states require electric trailerbrakes for trailers over a specified weight.Be sure to check state regulations for thisspecified weight. The maximum trailerweights listed may be limited to thisspecified weight, as the vehicle’s electricalsystem may not include the wiringconnector needed to activate electric trailerbrakes.
Your vehicle may tow a trailer provided themaximum trailer weight is less than orequal to the maximum trailer weight listedfor your vehicle configuration on thefollowing chart.
