4WD HIGH TEMP IS DISPLAYED ON INFORMATION DISPLAY
Description
INFOID:0000000011004036
While driving, 4WD warning (4WD High Temp. Stop vehicle) is displayed on information display (combination
meter).
• This symptom protects drivetrain parts when a heavy load is applied to the electric controlled coupling and
multiple disc clutch temperature increases. Also, optional distribution of torque sometimes becomes rigid
before 4WD warning (4WD High Temp. Stop vehicle) is displayed. Both cases are not malfunction. Refer to
DLN-134, "Protection Function"
• When this symptom occurs, stop vehicle and allow it to idle for some times. Displays will stop and system
will be restored.
