4WD HIGH TEMP IS DISPLAYED ON INFORMATION DISPLAY

Description

INFOID:0000000010755292

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-26, "Protection Function"

.

• When this symptom occurs, stop vehicle and allow it to idle for some times. Displays will stop and system

will be restored.
