2004 Mazda MAZDA3 Owner's Manual - Page 123

Driving Your Mazda Starting and Driving M ABS Warning Light* 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. 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. M Brake 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. When the brake pedal is depressed hard or depressed more quickly, the brakes apply more firmly. NOTE WARNING ABS Warning Light and Brake Warning Light on at the Same Time: Driving when the brake system warning light and ABS warning light are on at the same time is dangerous. When both lights are on, the rear wheels could lock more quickly in an emergency stop than under normal circumstances. Don't drive with both lights on, and contact an Authorized Mazda Dealer to have the brakes inspected as soon as possible. • 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. • When the brake pedal is depressed hard or depressed more quickly, a clicking noise from the brake booster may be heard. This is a normal effect of the brake assist and does not indicate an abnormality. • The brake assist equipment does not supersede the functionality of the vehicle's main braking system. 5-8 *Some models.
