control system could lead to an increased  
risk of loss of vehicle control, vehicle  
rollover, personal injury and death.

technology cannot defy the laws of  
physics. Its 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  
The stability control system has several  
features built into it to help you maintain

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 operators 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 enhances your vehicles 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 system enhances your vehicles ability  
to maintain traction of the wheels by  
detecting and controlling wheel spin. See  
Using Traction Control (page 148).  
The system automatically turns on each  
time you switch the ignition on.
