Anti-Lock Brake System Warning Light With the anti-lock brake system, the light will come on when your engine is started and may stay on for several seconds. That is normal. Low Tire Pressure Warning Light This light will come on briefly as you start the engine, for vehicles equipped with the Tire Pressure Monitor System. If the ABS warning light comes on and stays on, there may be a problem with the antilock portion of the brake system. If the red BRAKE light is not on, you still have brakes, but you do not have antilock brakes. See Brake System Warning Light on page 3-62. If the light stays on, turn the ignition to OFF/ACC. If the light comes on when you are driving, stop as soon as possible and turn the ignition off. Then start the engine again to reset the system. If the light still stays on, or comes on again while you are driving, your vehicle needs service. If the regular brake system warning light is not on, you still have brakes, but you do not have anti-lock brakes. If the regular brake system warning light is also on, you do not have anti-lock brakes and there is a problem with your regular brakes. See Brake System Warning Light on page 3-62. It will then come on only when a flat or low tire pressure condition exists. See Tire Pressure Monitor System on page 5-59 for more information. 3-63
