Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
STC/DSTC switch
The switch for STC/DSTC is positioned next to the other buttons on the lower section of the climate control module (CCM). The stability and traction control functions can be switched on and off manually (this applies only to the stability function from model year 2003 inclusive). When the ignition is switched on all functions are engaged. The switches have a green LED indicator which display the ON-position. When STC/DSTC is switched on or off, this is confirmed by a message in the driver information module (DIM). If the STC-/DSTC function is disabled, the other functions work normally.
