While driving, AWD warning lamp blinks 2 times in 1 second and it turns OFF after 1 minute.
• 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 lamp blinks quickly. Both cases are not malfunction.
