Driving BRAKES Your service brakes are self-adjusting. Refer to the "Service Guide" for scheduled maintenance. Occasional brake noise is normal and often does not indicate a performance concern with the vehicle's brake system. In normal operation, automotive brake systems may emit occasional or intermittent squeal or groan noises when the brakes are applied. Such noises are usually heard during the first few brake applications in the morning; however, they may be heard at any time while braking and can be aggravated by environmental conditions such as cold, heat, moisture, road dust, salt or mud. If a "metal-to-metal," "continuous grinding" or "continuous squeal" sound is present while braking, the brake linings may be worn-out and should be inspected by a qualified service technician. Rear anti-lock brake system (RABS) Rear Anti-lock Brake System (RABS) is standard equipment on this vehicle. RABS is designed to help you maintain directional stability in emergency stopping situations. With RABS, the rear brakes are kept from locking during panic stops; however, the front wheels can lock because they are not controlled by RABS. A clicking noise and slight pedal pulsation during RABS braking events indicates the RABS is functioning. Pedal pulsation coupled with clicking noise while braking under panic conditions on loose gravel, wet or snowy roads is normal and indicates proper functioning of the vehicle's RABS. If the vehicle has continuous vibration or shudder in the steering wheel while braking, the vehicle should be inspected by a qualified service technician. The RABS operates by detecting the onset of rear wheel lockup during brake applications and compensating for this tendency. RABS warning lamp The ABS warning lamp in the instrument cluster illuminates if a RABS fault is detected. Have your vehicle serviced as soon as possible. Normal braking is still effective unless the BRAKE warning lamp is ! also illuminated. BRAKE 103
