● If the 4WD shift indicator light indication changes to 2WD when the 4WD shift switch is shifted to the AUTO or 4H position at low ambient temperatures, the 2WD mode may be being engaged due to malfunctioning drive system. If the indicator does not return to normal and the 4WD warning light comes on, have the system checked by the nearest NISSAN dealer. The 4WD warning light comes on when the ignition switch is turned to ON. It turns off soon after the engine is started. If any malfunction occurs in the 4WD system when the ignition switch is ON, the warning light will either remain illuminated or blink. If the 4WD warning light comes on, the 4WD shift indicator light goes out. High-temperature transfer case oil makes the warning light blink rapidly (about twice per second). If the warning light blinks rapidly during operation, stop the vehicle in a safe place immediately. Then if the light goes off after a while, you can continue driving. A large difference between the diameters of front and rear wheels will make the warning light blink slowly (about once per two seconds). Change the 4WD shift switch into 2WD and do not drive fast. ● Shifting between 4H and 4LO is not recommended when the 4WD warning light turns on. ● When the warning light comes on, the 2WD mode may be engaged even if the 4WD shift switch is in AUTO or 4H. Be especially careful when driving. If corresponding parts are malfunctioning, the 4WD mode will not be engaged even if the 4WD shift switch is shifted. ● Do not drive the vehicle in the 4H or 4LO position on dry hard surface roads. Driving on dry, hard surfaces in 4H or 4LO may cause unnecessary noise, tire wear and increased fuel consumption. If the 4WD warning light turns on when you are driving on dry hard surface roads: - in the AUTO or 4H position, shift the 4WD shift switch to 2WD. - in the 4LO position, stop the vehicle, move the shift selector to the N position with the brake pedal depressed, and shift the 4WD shift switch to 2WD. 4WD warning light Warning light Comes on or blinks when: There is a malfunction in the 4-wheel drive system The transfer case oil temperature is abnormally high The difference in wheel rotation is large Comes on Blinks rapidly CAUTION ● If the warning light comes on or blinks slowly during operation or rapidly after stopping the vehicle for a while, have your vehicle checked by a NISSAN dealer as soon as possible.
