The indicator light may blink while shifting from one drive mode to the other. The 4LO indicator light must stop blinking and remain illuminated or turn off before shifting the transmission into gear. If the transmission selector lever is shifted from the N position to any other gear when the 4LO indicator light is blinking, the vehicle may move unexpectedly. When you shift between 4H and 4LO, follow the instructions below: ● For automatic transmission models, stop the vehicle and shift the transmission selector lever to the N position with the brake pedal depressed, then depress and turn the 4WD shift switch to 4LO or 4H. ● For manual transmission models, stop the vehicle and shift the transmission selector lever to the N position with the clutch pedal depressed, then depress and turn the 4WD shift switch to 4LO or 4H. You cannot move the transfer 4WD shift switch between 4H and 4LO unless you stop the vehicle and shift the transmission selector lever to the N position with the brake pedal (AT models) or clutch pedal (MT models) depressed. Turn signal/hazard indicator lights The appropriate light flashes when the turn signal switch is activated. Both lights flash when the hazard switch is turned on. If the battery is removed or discharged, the vehicle dynamic control system is disabled and the VDC indicator light will not turn off after 2 seconds when the ignition switch is turned to the ON position. To reset the system, you must perform the reset procedure. Refer to "Vehicle dynamic control (VDC) system" in the "Starting and driving" section of this manual. If the light does not go off after performing the reset procedure, have the traction control system checked by a NISSAN dealer. While the vehicle dynamic control system is operating, you might feel slight vibration or hear the system working when starting the vehicle or accelerating, but this is normal. The VDC system will be disabled and the VDC light will illuminate when the electronic locking rear differential (E-lock) system switch (if so equipped) is turned on and the E-lock system is engaged. If the E-lock system disengages or the switch is turned off, the VDC system will be enabled and the VDC light will turn off. Vehicle dynamic control off indicator light (if so equipped) This indicator light comes on when the vehicle dynamic control off switch is pushed to OFF, the transfer case is in the 4LO position ( model), or when the vehicle dynamic control system is not functioning properly. This indicates the vehicle dynamic control system is not operating. Push the vehicle dynamic control off switch again or restart the engine and the system will operate normally. See "Vehicle dynamic control (VDC) system" in the "Starting and driving" section of this manual. The vehicle dynamic control light also comes on when you turn the ignition key to the ON position. The light will turn off after about 2 seconds if the system is operational. If the light stays on or comes on along with the SLIP indicator light while you are driving, have the vehicle dynamic control system checked by a NISSAN dealer. 2-20 Instruments and controls
