New tread
Worn tread
Tread wear indicator
Each tire incorporates a tread wear
indicator, which becomes visible
when the depth of the tread grooves
decreases to 0.063 in (1.6 mm). A
tire must be replaced when the
tread wear indicator appears as a
solid band across the tread...
The disc brakes have audible wear indicators
on the brake pads. If the brake
pads wear close to their service limit, the
wear indicator makes a very audible
scraping noise when the brake pedal is
applied.
If you hear this scraping noise each time
you apply the brake pedal, have the brake
pads serviced by your SUBARU dealer as
soon as possible...
