If 4WD warning lamp turns ON, perform self-diagnosis. Refer to 

DLN-23, "CONSULT-III Function (ALL MODE AWD/4WD)"

.

NOTE:

• Light tight-corner braking symptom may occur depending on driving conditions in AUTO mode.  This is not a

malfunction.

• Heavy tight-corner braking symptom occurs when vehicle is driven in the following conditions: 4WD shift

switch is 4H or 4LO, steering wheel is turned fully to either side.
