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.

WHAT IS G.O.A.T. MODE
CONTROL
Your vehicle has several goes overany-type of terrain (G.O.A.T.) modes thatyou can select for different drivingconditions. Depending on the mode thatyou select, the system adjusts variousvehicle settings.
HOW DOES G.O.A.T. MODE
CONTROL WORK
Each selectable mode changes variouselectronic and mechanical settings withinyour vehicle to tailor its performance anddriving characteristics to on-road oroff-road driving conditions. The systemmay alter steering feel and effort, tractioncontrol, stability control, chassis controls,powertrain response, transmission shiftpoints, four-wheel driveline setting,exhaust noise level and suspensiondampening to predetermined settings,depending upon the mode that you select.
The system reverts to the normal modeeach time you start your vehicle. At startupthe system also displays a prompt on theinstrument cluster display that gives youthe option to return to the previouslyselected drive mode during the last ignitioncycle. If you select yes, the system returnsto the last selected drive mode and thedefault driveline settings associated withthat mode. If you select no or do not makea selection within a short time, the systemremains in normal mode and the drivelinesettings remain the same as selected inthe prior ignition cycle.
Note:Your vehicle has diagnostic checksthat continuously monitor all systems forproper operation. If a mode is unavailabledue to a system fault, your vehicle defaultsto normal mode and the driveline remainsin the four-wheel drive setting that you lastselected prior to the system fault.
