There is one sentence in the manual under the power steering heading that states (see bold text below):
"The power steering system is designed to provide power assistance while driving to operate
the steering wheel with light force.
When the steering wheel is operated repeatedly
or continuously while parking or driving at a very
low speed, the power assist for the steering
wheel will be reduced. This is to prevent overheating of the power steering system and protect
it from getting damaged. While the power assist
is reduced, steering wheel operation will become
heavy. If the steering wheel operation is still performed, the power steering may stop and the
power steering warning light will illuminate. In a
safe location, stop the engine and push the ignition switch to the OFF position. The temperature
of the power steering system will go down after a
period of time and the power assist level will
return to normal after starting the engine. The
power steering warning light will go off. Avoid
repeating such steering wheel operations that
could cause the power steering system to overheat.
You may hear a noise from the front of the vehicle
when the steering wheel is operated. This is a
normal operational noise and is not a malfunction.
If the power steering warning light illuminates
while the engine is running, it may indicate the
power steering system is not functioning properly
and may need servicing. Have the power steering
system checked by a NISSAN dealer.
When the power steering warning light illuminates with the engine running, the power assist
for the steering will cease operation but you will
still have control of the vehicle. At this time,
greater steering efforts are required to operate
the steering wheel, especially in sharp turns and
at low speeds"
... mine makes noise regardless of steering wheel movement. And, is this noise they speak of the sound of a groaning pump as would be expected, or the high pitched whines I am hearing. Way to be vague nissan. In other explanations of noise, such as the ABS system, they describe the noise as a "clunk". Sure would have been handy information for the salesperson to relay to me so I could make an informed decision.
