(4) Loosen the bolt fixing the shift lock cable unit, push the 

lever in direction B and the unit in direction C and tighten 
the bolt at the standard torque.

Tightening torque: 5.0 

± 1.0 N⋅m (44 ± 9 in-lb)

(5) Lift the lock guide of the key interlocking cable and then 

unlock it.

(6) Lower the lock guide of the key interlocking cable and 

then lock it.
NOTE: The key interlocking cable is adjusted according 
to the lock position (cap push state) at this time. Readjust 
the lock position if key interlocking operations malfunction 
after locking.

3. After adjustment, re-check the operations. Replace the shift 

lock cable unit if operations are defective (Refer to 

P.23A-561

).

ADJUSTMENT

M1231119500035

1. Move the selector lever to the "N" position.
2. Loosen the upper control lever adjusting nut.
3. Check that the transmission range switch is at "N" position.
4. Adjust the upper control lever so that there is no slackness 

or excessive tightness in the transmission control cable, and 
then tighten the adjusting nut to the specified torque.

Tightening torque: 23 

± 4 N⋅m (17 ± 3 ft-lb)

5. Check that the transmission operation and functioning in 

each position corresponds accurately to the position of the 
selector lever.
