VARIABLE VOLTAGE CONTROL SYSTEM Vehicles operated in high temperatures or under severe conditions require frequent checks of the battery fluid level. If you add electrical accessories to your vehicle ground it to the body ground A located near the battery along the negative battery cable. JUMP STARTING If jump starting is necessary, see "Jump starting" in the "In case of emergency" section of this manual. If the engine does not start by jump starting, the battery may have to be replaced. Contact a NISSAN dealer. LDI0454 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.
