WARNING
∙ If the engine is not running or is turned offwhile driving, the power assist for the
steering will not work. Steering will be
harder to operate.
∙ When the power steering warning light illuminates with the engine running,
there will be no power assist for the
steering. You will still have control of the
vehicle but the steering will be harder to
operate. Have the power steering system
checked. It is recommended that you visit
an INFINITI retailer for this service.
The power steering system is designed to
provide power assist while driving to operate
the steering wheel with light force.
When the steering wheel is operated repeat-
edly or continuously while parking or driving
at a very low speed, the power assist for the
steering wheel will be reduced. This is to pre-
vent overheating of the power steering sys-
tem 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 igni-
tion switch to the OFF position. The temperature of the power steering sys-
tem 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 sound from the front of the
vehicle when the steering wheel is operated
quickly. This is a normal operational noise and
is not a malfunction.
If the power steering warning light
PSillumi-
nates while the engine is running, it may indi-
cate the power steering system is not func-
tioning properly and may need servicing.
Have the power steering system checked. It is
recommended that you visit an INFINITI re-
tailer for this service.
When the power steering warning light illu-
minates with the engine running, there will be
no power assist for the steering but you will
still have control of the vehicle. At this time,
greater steering effort is required to operate
the steering wheel, especially in sharp turns
and at low speeds.
For additional information, refer to “Power
steering warning light” in the “Instruments
and controls” section of this manual.
