CAUTION
●Do not ground accessories directly to
the battery terminal. Doing so will by-
pass the variable voltage control sys-
tem and the vehicle battery may not
charge completely.
●Use electrical accessories with the en-
gine 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 elec-
trical accessories to your vehicle, be sure to
ground them to a suitable body ground such as
the frame or engine block area.
1. Drive belt automatic tensioner
2. Alternator
3. A/C compressor
4 Crankshaft pulley
WARNING
Be sure the ignition key is in the OFF or
LOCK position before servicing drive belt.
The engine could rotate unexpectedly.
1. Visually inspect the belt for signs of unusual
wear, cuts, fraying or looseness. If the belt is
in poor condition or is loose, have it replaced
or adjusted by an INFINITI retailer.
