Stability Control

PRINCIPLE OF OPERATION WARNINGS Vehicle modifications involving braking system, aftermarket roof racks, suspension, steering system, tire construction and wheel and tire size may change the handling characteristics of your vehicle and may adversely affect the performance of the electronic stability control system. In addition, installing any stereo loudspeakers may interfere with and adversely affect the electronic stability control system. Install any aftermarket stereo loudspeaker as far as possible from the front center console, the tunnel, and the front seats in order tominimize the risk of interfering with the electronic stability control sensors. Reducing the effectiveness of the electronic stability control system could lead to an increased risk of loss of vehicle control, vehicle rollover, personal injury and death. Remember that even advanced technology cannot defy the laws of physics. It’s always possible to lose control of a vehicle due to inappropriate driver input for the conditions. Aggressive driving on any road condition can cause you to lose control of your vehicle increasing the risk of personal injury or property damage. Activation of the electronic stability control system is an indication that at least some of the tires have exceeded their ability to grip the road; this could reduce the operator’s ability to control the vehicle potentially resulting in a loss of vehicle control, vehicle rollover, personal injury and death. If your electronic stability control system activates, SLOW DOWN. The system automatically turns on each time you switch the ignition on.

If a fault occurs in either the stability control or the traction control system, you may experience the following conditions: • The stability and traction control light illuminates steadily. • The stability control and traction control systems do not enhance your vehicle's ability to maintain traction of the wheels. If a driving condition activates either the stability control or the traction control system you may experience the following conditions: • The stability and traction control light flashes. • The brake pedal is stiffer than usual. • If the driving condition is severe and your foot is not on the brake, the brake pedal maymove as the systemapplies higher brake force. The stability control system has several features built into it to help you maintain control of your vehicle: Electronic Stability Control The systemenhances your vehicle’s ability to prevent skids or lateral slides by applying brakes to one or more of the wheels individually and, if necessary, reducing engine power. Traction Control The systemenhances your vehicle’s ability to maintain traction of the wheels by detecting and controlling wheel spin. See Using Traction Control (page 148). • Your vehicle slows down. • Reduced engine power. • A vibration in the brake pedal.
