noting the following points:
Adjustment of select lever and control rod
1. Place the vehicle on a level surface.NOTE: If the vehicle is not on level surface, the shift
select cable set positions will vary with the movement of
engine. To prevent possible misadjustment of the cable,
the vehicle must be placed on a level surface.

select lever (2), and then place the lever in the “N”
position.
3. Set select lever in the “N” position.
4. Push select lever forward (“R” position side) and
s e c u r e i t ( u s i n g a r u b b e r b a n d ( 3 ) , e t c . ) s o t h a t t h e p i n
comes into contact with the wall of the detent plate.
5. Install the shift control rod (1) to the selector lever arm
(4).

6. After adjustment, make sure that the selector lever
operates normally, and that each selector position is
properly indicated. (The red mark shows through the
window.)
Adjustment of shift lock cable
1. Set ignition key in “LOCK” position and selector lever
in “P” position.
2. Adjust cable screw cap on selector lever side to
provide a gap (slack for cable) of 1 – 2 mm between
rod on steering lock side and stopper.
Adjust cap as follows:
a. Pull screw cap (1) in arrow direction to remove
inner cable slack.
b. With cable kept as (a), adjust gap between nut (2)
and bracket to 5 mm (0.2 in).
c. Lock inner cable by turning nut (3) while holding nut
(2) in place.
Torque : 3.7 N
m (38 kgꞏcm/33 lb in)
