Contact your Toyota dealer as soon as possible to service the vehicle. (i) "ABS" Warning Light The light comes on when the ignition key is turned to the "ON" position. If the anti-lock brake system and the brake assist system work properly, the light turns off after a few seconds. Thereafter, if either of the systems malfunctions, the light comes on again. When the "ABS" warning light is on (and the brake system warning light is off), the anti-lock brake system, the brake assist system, the vehicle skid control system and/or active traction control system do/ does not operate, but the brake system still operates conventionally.
