CAUTION
●Do not ground accessories directly to the
battery terminal. Doing so will bypass the
variable voltage control system and the ve-
hicle battery may not charge completely.
● Use electrical accessories with the engine
running to avoid discharging the vehicle
battery.
The variable voltage control system measures
the amount of electrical discharge from the
battery and controls voltage generated by the
generator.
1. Power steering fluid pump
2. Alternator
3. Crankshaft pulley
4. Air conditioner compressor
5. Drive belt auto-tensioner
WARNING
Be sure the ignition switch is in the OFF or LOCK
position before servicing drive belts. The en-
gine could rotate unexpectedly.
1. Visually inspect each belt for signs of unusual wear, cuts, fraying or looseness.
If the belt is in poor condition or loose,
have it replaced or adjusted by an INFINITI
