If the four−wheel drive indicator light continues to blink and the buzzer sounds when you operate the front drive control switch knob from the "H2" to the "H4" position, this reminds you that the transfer mode is not in "H4" mode. Stop the vehicle or reduce the vehicle speed to less than 100 km/h (62 mph). Operate the switch knob again. CAUTION Never operate the front drive control switch knob if the wheels are slipping. Stop the slipping or spinning before operating. 2007 TACOMA from Sep. '06 Prod. (OM35877U) 181
