ELECTRONIC LOCKING REAR DIFFERENTIAL (E-Lock) SYSTEM (if so equipped) ● When the warning light comes on, the 2WD mode may be engaged even if the 4WD shift switch is in 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 4H position, shift the 4WD shift switch to 2WD. - in the 4LO position, stop the vehicle, move the automatic transmission shift selector to the N position with the brake pedal depressed, and shift the 4WD shift switch to 2WD. ● If the warning light is still on after the above operation, have your vehicle checked by a NISSAN dealer as soon as possible. ● The transfer case may be damaged if you continue driving with the warning light blinking. The E-Lock system can provide additional traction and should only be used when a vehicle has become or is becoming stuck. This system operates by electronically "locking" the two rear drive wheels together, allowing them to turn at the same speed. The system is used when it is not possible to free a stuck vehicle even when using the 4LO position (4 wheel drive vehicles). When added traction is required, activate the E-Lock system by pushing the switch ON. See "Electronic locking rear differential (E-Lock) system switch" in the "Instruments and Controls" section. Once the system fully engages, the indicator light in the instrument panel will remain ON. When the system is activated, both rear wheels will engage, providing added traction. The rear wheels may momentarily slip or move to engage the system, and the system will only engage up to approximately 4 MPH (7 km/h). Once the vehicle is free, the system should be turned OFF and driving resumed. The Anti-Lock Brake (ABS) system is disabled and the ABS light illuminates when the E-Lock system is ON. Also, the Vehicle Dynamic Control (VDC) system is disabled and the VDC light illuminates when the E-Lock system is ON. Starting and driving 5-29
