WHAT IS TRACTION CONTROL
The traction control system helps to avoiddrive wheel spin and loss of traction.
HOW DOES TRACTION CONTROL
WORK
If your wheels begin to spin, the loss oftraction can compromise steering controland stability of the vehicle. The tractioncontrol system applies the brakes toindividual wheels and when needed, reducesengine power at the same time to increasetraction.
SWITCHING TRACTION CONTROL
ON AND OFF
WARNING: Operating your vehiclewith the traction control disabled couldlead to an increased risk of loss of vehiclecontrol, vehicle rollover, personal injuryand death.
The system turns traction control and stabilitycontrol on each time you power on yourvehicle.

HOW DOES STABILITY CONTROL
WORK
WARNING: Vehicle modificationsinvolving braking system, aftermarket roofracks, suspension, steering system, tireconstruction and wheel and tire size maychange the handling characteristics of yourvehicle and may adversely affect theperformance of the electronic stabilitycontrol system. In addition, installing anystereo speakers may interfere with andadversely affect the electronic stabilitycontrol system. Reducing the effectivenessof the electronic stability control systemcould lead to an increased risk of loss ofvehicle control, vehicle rollover, personalinjury and death.
WARNING: Remember that evenadvanced technology cannot defy the lawsof physics. 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 vehicle
increasing 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 theroad; this could reduce the operator'sability to control the vehicle potentiallyresulting in a loss of vehicle control, vehiclerollover, 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 in theloss of control of your vehicle, personalinjury 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.

ELECTRIC POWER STEERING
HOW DOES ELECTRIC POWERSTEERING WORK
The electric power steering system assiststhe brake system to help operate advancedstability control and accident avoidancesystems.
If your vehicle loses electrical power ordetects a concern when you are driving thesystem switches off and you retain normalsteering function. Additionally, whenever thebattery is disconnected or a new battery isinstalled, you must drive your vehicle a shortdistance before the system relearns thestrategy and reactivates all systems.
ELECTRIC POWER STEERINGPRECAUTIONS
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 thevehicle off. After at least 10 seconds, switchthe vehicle on and watch the informationdisplay for a steering system warningmessage. If a steering system warningmessage returns, have the system checkedas soon as possible.
WARNING: If the system detects anerror, you may not feel a difference in thesteering, however a serious condition mayexist. Have your vehicle checked as soonas possible. Failure to do so may result inloss of steering control.
