MECHANISM
Shift Lock System
Unless the brake pedal is being depressed, the

selector lever cannot be shifted to any other position
from the “P” position. Moreover, if the ignition key

is in “LOCK” position or if the key has been removed,

the selector lever cannot be shifted to any other

position from

position even if the brake pedal

is depressed.

1. WHEN BRAKE PEDAL IS NOT DEPRESSED

When the selector lever is in

position and

the brake pedal is not depressed, the detent
pin is locked because the shift lock pin locks
the lock cam, therefore, the selector pushbutton
cannot be pressed and the lever cannot be
shifted from the “P” position.

2. WHEN BRAKE PEDAL IS DEPRESSED

When the brake pedal is depressed in the afore-

mentioned condition the inner cable of the
shift lock cable is pulled in the direction of the
arrow in the figure and the lock cam,

which is interlinked with the shift lock pin, is

released. As a result, the selector pushbutton

can be pressed and the selector lever can be
shifted from

position to another position.

SHIFTING TO

POSITION FROM ANOTHER

POSITION
In the case of shifting to “P” position from another
position (for example,

position), the lock

cam is held in the position shown in the figure
by the force of the shift lock pin return spring;
consequently, there is no need to depress the

brake pedal. When the selector lever is shifted

to “P” position and the selector lever pushbutton
is released, the lock cam is rotated
while the detent pin moves upward. Conse-
quently, the shift lock pin is pressed down on

by the force of the return spring and the lock
cam is locked. In this way, the selector lever
is held fixed in the

position.

Key Interlock System
Unless the selector lever is in

position, the igni-

tion key cannot be turned to the “LOCK” position,
and the key cannot be removed.

The key interlock device installed in the inside of
the ignition key cylinder consists of the slide lever,
cam lever and revolving cam.
The slide lever is connected to the key interlock

cable. When the selector lever is operated, the slide

lever moves to interlock with the cam lever. The
revolving cam is designed to interlock with the igni-

tion key.

WHEN THE IGNITION KEY IS IN THE LOCK

POSITION OR PULLED OUT

The cam lever meshes with the projection on
the revolving cam inside the ignition key cylinder
to restrict movement of the slide lever that is
connected with the cam lever. As a result, since
turning of lock cam is restricted and movement

of the detent pin is hindered, the selector lever
pushbutton cannot be depressed and the selec-
tor lever cannot be moved to any position other
than the “P” position.

WHEN THE IGNITION KEY IS IN ANY

POSITION BUT LOCK POSITION (SELECTOR
LEVER IS IN

POSITION)

The projection on the revolving cam inside the

ignition key cylinder is in a position where it
does not hinder movement of the cam lever
and the restriction of the slide lever connected
with the cam lever is released. As a result, when
the pushbutton of the selector lever is pressed,
lock cam is turned in the direction of the arrow
shown in the illustration and the detent pin
moves down.
As a

selector lever can be moved

to any

other than the

position.

NOTE

While the brake pedal is not depressed, the
selector lever cannot be moved to any position
other than the

position even if the ignition

key is not in the “LOCK” position. (Refer to the
section of SHIFT LOCK SYSTEM.)
