BRAKE PAD WEAR WARNING
The disc brake pads have audible wear
warnings. When a brake pad requires re-
placement, it will make a high pitched
scraping sound when the vehicle is in mo-
tion. This scraping sound will first occur
only when the brake pedal is depressed.
Af ter more wear of the brake pad, the
sound will always be heard even if the
brake pedal is not depressed. Have the
brakes checked as soon as possible if the
wear warning 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 nor-
mal and does not affect the function or
performance of the brake system.
Proper brake inspection intervals should
be followed.
