it turns your traction control system on or off. if you have the system on the tires will slow automatically if they begin to slip and when you get traction again the tires will engage fully, when it is off you press the gas pedal and the tires will spin freely without slowing to get traction. if you are a drifter you want trac off
In general, if you see this light come on while driving a car with traction control, it means that the system has detected a loss of traction on one or more wheels. The traction control system will engage to correct it. Usually it only lights up briefly. If that light stays on all the time, there's something wrong with the sensor or the electrical connection to the light.
you may be losing traction. or u may have a sensor going out
When you engage the clutch and the engine sits there spinning: it get's no traction OR when there is no pressure on the clutch pedal: pressing it changes nothing.
there is a high pressure switch on the line or the accumalator, unplug it and place a jumper wire into the connector
ASR is like just as the same as traction control on American cars, if one of the wheels lose traction on the road and spin more than the others the ASR will engage and electronically apply the brakes on that wheel, if it happens on 2 wheels it will apply the brakes to both wheels and slow the engine down.
The only way to get those lights to turn off on the dashboard is to re-engage your traction control and buckle your seat belt - there isn't a way to get just those two lights to not illuminate on your dashboard.
Rivalry for control of the Western Mediterranean.
un hook the cruise control
If the cruise control will not engage, there might be a problem with the Electronic Fuel Injector or the MAP Sensor. There might also be a problem with the Oxygen Sensor. Some autos have more than one oxygen sensor.

If the car has traction control you must disengage it first, then if you are doing a stand still burnout engage the parking brake provided that they work. If you are doing this from a traffic light and plan to proceed down the road disengage the t/c and then hope that your car has enough juice to spin the tires
