Nissan Altima Owners Manual: Variable voltage control system
CAUTION
● Do not ground accessories directly to the battery terminal. Doing so will bypass the variable voltage control system and the vehicle battery may not charge completely.
● Use electrical accessories with the engine running to avoid discharging the vehicle battery.
Your vehicle is equipped with a variable voltage control system. This system measures the amount of electrical discharge from the battery and controls voltage generated by the generator.
The current sensor is located near the battery along the negative battery cable. If you add electrical accessories to your vehicle, be sure to ground them to a suitable body ground such as the frame or engine block area.
Battery
● Keep the battery surface clean and dry.
Clean the battery with a solution of baking
soda and water.
● Make certain the terminal connections are
clean and securely tightened.
