• When AWD warning lamp is ON, vehicle changes to front-wheel drive or shifting driving force-AWD (rear

wheels still have some driving torque).

• AWD system activates its protection function (shuts down AWD system temporarily) if AWD system detects

high load continuously or the front wheel tire size differs from the rear tire size. (AWD system is automati-
cally restored if AWD system no longer detects any overload or the tire size difference is eliminated.)

*1: Quick blinking: 2 times/second (blinking for approx. 1 minute and then turned OFF)

*2: Slow blinking: 1 time/2 seconds (Continuing to blink until ignition switch is turned OFF)

If AWD warning lamp turns ON, perform self-diagnosis.

NOTE:

Light tight-corner braking symptom may occur depending on driving conditions. This is not malfunction.

Heavy tight-corner braking symptom occurs 
when the vehicle is driven and the steering 
wheel is turned fully to either side after the 
engine is started. (See NOTE.)

• While driving
• Steering wheel is 

turned fully to either

Vehicle does not enter AWD mode even 
though AWD warning lamp turned to OFF.

While driving

DLN-147, "De-

scription"

AWD solenoid

Mechanical malfunction of electric con-
trolled coupling (Mechanical engage-
ment of clutch is not possible.)

While driving, AWD warning lamp blinks 
quickly. (When blinking in approx. 1 minute 
and then turning OFF.)
Quick blinking: 2 times/second

While driving

Protection function is activated due to 
heavy load to electric controlled cou-
pling. (AWD system is not malfunction-
ing. Also, optional distribution of torque 
sometimes becomes rigid before lamp 
blinks quickly, but it is not malfunction.)

DLN-148, "De-

scription"

While driving, AWD warning lamp blinks 
slowly. (When continuing to blink until turn-
ing ignition switch OFF)
Slow blinking: 1 time/2 seconds

• While driving
• Vehicle speed: 20 km/h 

(12 MPH) or more

Tire size is different between front and 
rear of vehicle.
