NOTE: LOCK Mode • Front/rear wheel torque distribution is fixed, ensuring stable driving when climbing slopes. the vehicle automatically returns to direct 4-wheel driving conditions. The AWD LOCK indicator lamp keeps • LOCK mode will change to AUTO mode automatically, when the vehicle has been driven at a high speed. The AWD LOCK indicator lamp turns off. • LOCK mode will change to AUTO mode automatically, when the ignition switch is turned “OFF”. Tire conditions are detected, and LOCK mode may be prohibited, or else speeds at which LOCK mode is • Heavy tight-corner braking symptom occurs when vehicle is driven in the following conditions: LOCK mode, steering wheel is turned fully to either sides, and accelerator pedal is depressed. CAUTION: Never switch to LOCK when rotation speed of front and rear wheel differs.
