SHIFT LOCK MECHANISM
Only when the following two conditions are satisfied,
the selector lever can be shifted from the P position
to another position:•When the brake pedal is depressed
•When the ignition key is in other than the LOCK
(OFF) position
When the brake pedal is not depressed

When the se lect or lever is in the P po sit i on wit h the
brake
pedal not d epressed, the shif tlock cable sto p
-
per keep s the lever lo cke d so that th e rod a nd lo ck
cam do no
t move.
As a result of this, th e pushbutto n of th e select or
lever linked
to the detent pin canno t be p r essed and
the selector le
ver canno t be shif ted f r om th e P posi
-
tion to anot her position.

When th

pulled by the shif

Then the lock cam linked to the ro d can also rot a te
so th
