SELECTOR LEVER OPERATION CHECK

M1231001300288

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

M1231120800029

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.
