1. Set the selector lever to the "N" position.
2. Loosen the control cable to manual control lever coupling

nut to free the cable and lever.

3. Set the manual control lever to the neutral position.
4. Loosen the transmission range switch body mounting bolts

and turn the transmission range switch body so the hole in
the end of the manual control lever and the hole (cross
section A

− A in the figure on the left) in the flange of the

transmission range switch body flange are aligned.
NOTE: The transmission range switch body can be aligned
by inserting a 5-mm diameter steel bar into the end hole of
the manual control lever and the flange hole of the transmis-
sion range switch body.

5. Tighten the transmission range switch mounting bolts to the

specified torque. Be careful at this time that the switch body
does not move.

Tightening torque: 11

± 1 N⋅m (98 ± 8 in-lb)

6. Gently pull the transmission control cable in the direction of

the arrow (B), until the cable is taut. Tighten the adjusting
nut.

Tightening torque: 23

± 4 N⋅m (17 ± 3 ft-lb)

7. Check that the selector lever is in the "N" position.
8. Check that each position of the manual control lever

matches each position of the selector lever using scan tool
MB991958.

SELECTOR LEVER OPERATION CHECK

M1231001300471

1. Apply the parking brake, and check that the selector lever

moves smoothly and accurately to each position.

2. Check that the engine starts when the selector lever is in the

"N" or "P" position, and that it does not start when the
selector lever is in any other position.

3. Start the engine, release the parking brake, and check that

the vehicle moves forward when the selector lever is moved
from the "N" position to 1st or 2nd gear in sport mode, and
that the vehicle reverses when the selector lever is moved to
the "R" position.

4. Stop the engine.
5. Turn the ignition switch to the "ON" position, and check that

the backup lamp illuminates when the selector lever is
shifted from the "P" to the "R" position.
NOTE: The A/T key interlock and shift lock mechanisms pre-
vent movement of the selector lever from the "P" position if
the ignition switch is in a position other than "LOCK" (OFF)
and the brake pedal is not depressed.

TRANSFER SHIFT LEVER OPERATION CHECK

M1231120800030

1. Check that the transfer shift lever moves smoothly and

correctly to each transfer gear position when the lever is
pushed downwards and moved.

2. Apply the parking brake, turn the ignition switch to the "ON"

position and move the selector lever to "N" position.

3. Check that the 4WD indicator light illuminates, flashes or

switches off according to the pattern shown in the illustration
when the transfer shift lever is move to each transfer
position.

4. If the selection is not completed even after 5 seconds or

more have passed, carry out the following procedure.

(1) Return the transfer shift lever to the position it was at

before selection.

(2) Start the engine, drive the vehicle straight forward, and

then stop the engine.

(3) Apply the parking brake, and then move the selector

lever to the "N" position.

(4) Operate the transfer shift lever once more.

NOTE: If the vehicle is not fully stopped or if the selector
lever is at a position other than "N" position when select-
ing 4HLc or 4LLc, the 4WD indicator light will flash more
quickly than normal, and the 4WD position will not be
selected. This is a normal phenomenon which serves to
control the smooth selection of 4HLc and 4LLc.
