If checking or replacement is required, it is

tailer for this service.If the brakes do not operate properly, it is
recommended that you have the brakes

INFINITI retailer for this service.
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
Have your brake system checked if the
brake pedal height does not return to nor-
mal. It is recommended that you visit an
INFINITI retailer for this service.
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, oc-
casional 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.
Proper brake inspection intervals should be
followed.
For additional information regard-
ing brake inspections, refer to the appropri-
ate maintenance schedule information in the
"Maintenance and schedules" (P. 9-2).

WARNING
• Tires should be periodically in-
spected for wear, cracking, bulg-
ing or objects caught in the tread.
If excessive wear, cracks, bulging
or deep cuts are found, the tire(s)
should be replaced. •
The original tires have built-in
tread wear indicators. When the
wear indicators are visible, the
tire(s) should be replaced.
• Tires degrade with age and use.
Have tires, including the spare,

qualified technician because some
tire damage may not be obvious.

prevent tire failure and possible
personal injury.

may result in serious personal in-
jury. If it is necessary to repair the
spare tire, it is recommended that
