A Brake Traction Control System (BTCS) for an off-road type vehicle includes a 2WD/4WD switch adapted to switch a drive mode of the vehicle between a two-wheel drive mode (2WD) and a four-wheel drive mode (4WD). The switch is configured to be manually activated by an associated vehicle operator. A control unit is in signal communication with the 2WD/4WD switch. The control unit is operable to activate the BTCS only if the drive mode is switched to the four-wheel drive mode and predetermined vehicle operating conditions relating to engine throttle position or opening and wheel speed are subsequently satisfied.
