BRAKES Rear window wiper blade Contact a NISSAN dealer if checking or replacement is required. If the brakes do not operate properly, have the brakes checked by a NISSAN dealer. Proper brake inspection intervals should be followed. For more information regarding brake inspections, see the appropriate maintenance schedule information in the "NISSAN Service and Maintenance Guide". Self-adjusting brakes Your vehicle is equipped with self-adjusting brakes. The front and rear disc-type brakes self-adjust every time the brake pedal is applied. WARNING See a NISSAN dealer for a brake system check if the brake pedal height does not return to normal. Brake pad wear indicators The disc brake pads on your vehicle have audible wear indicators. When a brake pad requires replacement, a high pitched scraping or screeching sound will be heard when the vehicle is in motion. The noise will be heard whether or not the brake pedal is depressed. Have the brakes checked as soon as possible if the wear indicator sound is heard. Under some driving or climate conditions, occasional brake squeak, squeal or other noise may be heard. Occasional brake noise during light to moderate stops is normal and does not affect the function or performance of the brake system. 8-20 Maintenance and do-it-yourself
