then turns off. If it remains on steadily (not flashing) after ignition, or if it illuminates
steadily while you are driving, the TCS or ESC system may not be fully functional or their
operation may be completely disabled. If this happens, your vehicle will still have normal
service braking and it still can be driven, although without the benefits of TCS or an ESC
system.

Flashes quickly when ESC or TCS intervenes to reduce risk of loss of control.

STOP Telltale light

In the event of a serious fault, the red STOP
telltale light comes on and an audible alarm will
sound if the engine is running. An illuminated
stop message light indicates a serious problem
has been detected, and the driver must respond
immediately to the problem.
When illuminating, this telltale light means the
vehicle must be safely pulled off the road and
stopped. In some instances, the engine must be
switched off immediately.
