Stability Control

Stability is controlled by the brake control module (BCM) sending a signal to the engine control module (ECM) to reduce engine torque if a drive wheel should start to spin and there is a reduction in road grip. Stability control is operable between 0 km/h (0 mph) and top speed. For traction control, see TRACTION CONTROL

Stability control can be engaged or disengaged manually by turning the function selector on the left steering wheel stalk until "DSTC/spincontrol on/off" appears in the driver information module display. The selection is then confirmed by pressing the "Reset" button. All functions are connected when the ignition is turned on. If the stability function is disengaged, the other functions will operate normally.
