Driving Your Mazda Warning/Indicator Lights and Beep Sounds qABS Warning Light qElectronic Brake Force Distribution System Warning The warning light stays on for a few seconds when the ignition switch is turned to the ON position. If the ABS warning light stays on while you're driving, the ABS control unit has detected a system malfunction. If this occurs, your brakes will function normally as if the vehicle had no ABS. Should this happen, consult an Authorized Mazda Dealer as soon as possible. NOTE When the engine is jump-started to charge the battery, uneven rpm occurs and the ABS warning light comes on. This is due to a weak battery, not a malfunction. Recharge the battery. If the electronic brake force distribution control unit determines that some components are operating incorrectly, the control unit may turn the brake system warning light and the ABS warning light on at the same time. The problem is likely to be the electronic brake force distribution system. WARNING Do not drive with both the ABS warning light and brake warning light illuminated. Have the vehicle towed to an Authorized Mazda Dealer to have the brakes inspected as soon as possible: Driving when the brake system warning light and ABS warning light are illuminated at the same time is dangerous. When both lights are illuminated, the rear wheels could lock more quickly in an emergency stop than under normal circumstances. 5-44
