Driving Your Mazda Starting and Driving 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 simultaneously is dangerous. When both lights are illuminated, the rear wheels could lock more quickly in an emergency stop than under normal circumstances. qBrake Pad Wear Indicator When the disc brake pads become worn, the built-in wear indicators contact the disc plates. This causes a screeching noise to warn that the pads should be replaced. 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. When the brake pedal is depressed hard or depressed more quickly, the brakes apply more firmly. NOTE l When you hear this noise, consult an Authorized Mazda Dealer as soon as possible. WARNING Do not drive with worn disc pads: Driving with worn disc pads is dangerous. The brakes could fail and cause a serious accident. As soon as you hear a screeching noise consult an Authorized Mazda Dealer. 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. When the brake pedal is depressed hard or depressed more quickly, a motor/pump operation noise 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. 5-9
