Driving Your Mazda Starting and Driving 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. 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. qElectronic Brake Force Distribution System Warning qBrake Assist During emergency braking situations when it is necessary to depress the brake pedal with greater force, the brake assist system provides braking assistance, thus enhancing braking performance. 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. When the brake pedal is depressed hard or depressed more quickly, the brakes apply more firmly. NOTE l l When the brake pedal is depressed hard or depressed more quickly, the pedal will feel softer but the brakes will apply more firmly. This is a normal effect of the brake assist operation and does not indicate an abnormality. The brake assist equipment does not supersede the functionality of the vehicle's main braking system. 5-8
