Here is how to use the TCL button on a 2010 Mitsubishi Endeavor:
1. Press the TCL button to turn on the traction control system. The TCL indicator light on the dashboard will illuminate when the system is engaged.
2. Drive the vehicle as you normally would. The traction control system will automatically engage when it detects that one or more wheels are losing traction.
3. If you need to disengage the traction control system, press the TCL button again. The TCL indicator light will turn off when the system is disengaged.
It is important to note that the traction control system is not a substitute for safe driving practices. Always drive cautiously and at a speed appropriate for the road conditions.
