Turn off the traction control on your car. There is usually a button on your car that will turn it off. If you cant find the button, it will show the location of the button in the manual of the car.
Since this varies by model and model year, it's best to the the Owners Manual for your vehicle - which has information about the traction controls and the on/off switching. There's also an extensive bit of traction control information in the "Related Questions"
The "trac" button is for traction control. By default, traction control is always on unless you turn it off.
In front of the gearshift ( according to the owners manual )
The traction control system has engaged and is applying the brakes and / or altering the power to the drive wheels to control wheel slip. Read your owners manual for specifics.
Because the traction control has been turned off. Locate the button to push to turn it back on. Your owners manual will list the location of this button.
low traction or service traction or ABS is my best guess. maybe i dunno check your OWNERS MANUAL? in my experience it seems to tell you those things
Split traction occurs when you are turning and breaking at the same time. Some traction is needed to turn while some is needed to slow down or speed up. Therefore the traction is split between two tasks.
The benefits on a manual treadmill are that it pretty cheap since I has a few components, takes less space and they is nothing to service since there is no motor.
