The 4WD warning light is located in the

The 4WD warning light is located in the meter. The 4WD warning light comes on when the ignition switch is placed in the ON position. It turns off soon after the engine is started.

If any malfunction occurs in the 4WD system when the ignition switch is placed in the ON position, the 4WD warning light will either remain illuminated or blink. If the 4WD warning light comes on, the 4WD shift indicator turns off. High-temperature transfer case oil makes the 4WD 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 turns off after a while, you can continue driving. A large difference between the diameters of front and rear wheels will make the 4WD warning light blink slowly (about once per two seconds). Change the 4WD shift switch to AUTO and do not drive fast.

CAUTION
► If the 4WD warning light comes on or blinks slowly during operation or rapidly after stopping the vehicle for a while, have your vehicle checked by an INFINITI retailer as soon as possible.
► Shifting between 4HI and 4LO is not recommended when the 4WD warning light turns on.
► When the 4WD 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 4HI or 4LO position on dry hard surface roads. Driving on dry, hard surfaces in 4HI or 4LO may cause unnecessary noise, tire wear and increased fuel consumption. If the 4WD warning light turns on when driving on dry hard surface roads: — in the AUTO or 4HI position, shift the 4WD shift switch to AUTO. — in the 4LO position, stop the vehicle and shift the transmission selector lever to the N (Neutral) position and shift the 4WD shift switch to AUTO.
► If the 4WD warning light is still on after the above operation, have your vehicle checked by an INFINITI retailer as soon as possible.
► The transfer case may be damaged if you continue driving with the warning light blinking.
