TUNDRA (34413U) CAUTION Do not use tires other than the manufacturer's designated tires, and do not mix tires or wheels of different sizes. You may prevent the antilock brake system from operating at full effectiveness. "ABS" warning light This light comes on when the ignition key is turned to the "ON" position. After a few seconds, the light will go off. If any of the following conditions occurs, this indicates a malfunction somewhere in the parts monitored by the warning light system. Contact your Toyota dealer as soon as possible to service the vehicle. D The light does not come on as described above, or remains on. D The light comes on while driving. Type A Even if the anti- lock brake system should fail, the brake system will still operate conventionally. However, when the "ABS" warning light is on (and the brake system warning light is off), the anti- lock brake system is not assisting brake performance so that the wheels can lock- up during sudden braking or braking on slippery road surfaces. Have your vehicle checked by your Toyota dealer as soon as possible. Type B 174
