Stability Control

|
WARNING: 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 to minimize 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.
WARNING: 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.286
If a driving condition activates either the stability control or traction control you may experience the following conditions:
The stability control system has several features built into it to help you maintain control of your vehicle:
Electronic stability control enhances 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.
Roll stability control enhances your vehicle’s ability to prevent rollovers by detecting your vehicle’s roll motion and the rate at which it changes by applying the brakes to one or more wheels individually.
Curve control enhances your vehicle’s ability to follow the road when cornering severely or avoiding objects in the roadway. Curve control operates by reducing engine power and, if necessary, applying brakes to one or more of the wheels individually.
Side wind stabilization is an advanced feature that works by carefully applying the brakes on one side of the vehicle to reduce the effect of a side wind gust on the vehicle's path.
Torque vectoring control applies brake torque on the inner driven wheel in a curve for better traction to avoid an understeer, or oversteer situation. Unlike electronic stability control, enhanced torque vectoring control does not slow the vehicle. It helps control excessive wheel slip and gives the vehicle improved cornering agility.
Traction control enhances your vehicle’s ability to maintain traction of the wheels by detecting and controlling wheel spin. See What Is Traction Control (page 284).
The system turns on each time you switch the ignition on.
You can switch the electronic stability control system off by pressing and holding the ESC off button for over 5 seconds, or you can press the button again to switch the system on.
Shifting the transmission into reverse (R) will disable the system.
You can switch the traction control system off or on independently. See Switching Traction Control On and Off (page 284).

1 The Traction Control system can still be enabled but with tighter or looser thresholds.
2 When you press and hold the button, a progress bar will display to show the button hold time progress.
3 Functions can vary depending on what selectable drive mode the vehicle is currently in.
If it does not illuminate when you switch the power on, or remains on, this indicates a malfunction.
Have your vehicle checked by an authorized dealer as soon as possible.
