Antilock Brake System (ABS) Warning Light For vehicles with the Antilock Brake System (ABS), this light comes on briefly when the engine is started. The ABS warning light will come on briefly when the ignition is turned to ON/RUN. This is normal. If the light does not come on then, have it fixed so it will be ready to warn if there is a problem. Hold Mode Light If the vehicle has this feature, this light comes on when the hold mode is active. If the light stays on, turn the ignition to LOCK/OFF or if the light comes on, 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 driving, the vehicle needs service. See your dealer/retailer. If the regular brake system warning light is not on, the brakes will still work, but the antilock brakes will not work. If the regular brake system warning light is also on, the antilock brakes will not work and there is a problem with the regular brakes. See Brake System Warning Light on page 3-28. If the HOLD mode light flashes, have the vehicle checked. See "Hold Mode" under Automatic Transmission Operation on page 2-22 for more information. 3-30
