Answer
Hi Jay,

Here's an excerpt from your Owner's manual:

ELECTRONIC TRACTION CONTROL
The purpose of electronic traction control is to maintain forward or rearward momentum of he vehicle when one or more wheels are spinning while others have good grip, e.g. if one wheel is on ice and others are on tarmac. The system
works by applying the brake to a spinning wheel in order to transfer torque to the remaining wheels.

NOTE: Traction control can operate up to speeds of 62 mph (100 km/h).

Warning light
The instrument panel has a traction control warning (TC) which illuminates for a minimum of 2 seconds whenever the system is active and also illuminates as a bulb check (for approximately 3 seconds) when the starter switch is turned to position ‘II'.

If there is a fault with the system, the warning light will illuminate continuously and remain illuminated when the vehicle is stopped, in which case you should contact your dealer at the earliest opportunity.

NOTE: Faults with the ETC system will invariably cause the Hill Descent Control warning light to illuminate too. In most cases the ABS and brake system lights will also
illuminate.

That grinding noise you hear is most likely your brakes working on one or more wheels.  The only other grinding noise I am aware of is when you are about to have serious CV joint (axle) problems.  Let's hope it's just your brakes.   When was the last time you had the brakes inspected?

Best of luck,

JohnMc
