178 Driving and Operating
The parking brake indicator light in
the instrument panel will come on
when the lever is pulled up. Before
you leave the driver's seat, follow
the steps under Parking, or Leaving
Driver's Seat . See Braking 0 134.
To release the parking brake, hold
the brake pedal down while pushing
the release button of the parking
brake lever and lower the lever. The
parking brake indicator light in the
instrument panel will go out.
The parking brake indicator light is
designed to remind you if the
parking brake is not released when
the engine control switch is on.
If the parking brake warning light
remains on when the parking brake
lever is lowered, a brake failure or a
drop in air pressure may be the
cause.
Check the brake air pressure for
correct level. If the brake air
pressure is low, contact your dealer
for service.
If you notice the parking brake lever
travel has increased over time, this
means the cable adjustment must
be checked by a qualified
technician. Adjustment may be
required due to parking brake shoe
wear. See Control of a Vehicle
0 130.
Inspection
Pull the parking brake lever slowly
from the fully released position while
counting the clicks produced as the
lever engages ratchet plate notches
to check that it can be raised the
proper amount and the lever is held
firmly.
If the number of notches is not
within the standard value range
below, adjust it to the standard
value. Lever stroke is 6 to 8
notches.
Number of notches before parking
brake is set when lever is pulled
slowly from released position with
pull force of about 147 N (15 kgf/
33 lbs).
