The place to go is: http://72.3.186.203/Home.aspx" onclick="window.open(this.href);return false;
Navigate as follows:
"on-line subscriptions"
select "Nissan Publications"
enter appropriate info under "how to find a publication"
It should select:"2011 Nissan LEAF Service Manual"
with icons at right that show delivery methods available.
A CD costs $210.
An "eye" with slashed circle over it, meaning
that on-line viewing is denied.
However... if you register for on-line access for one day, (about $20 as I recall),
you can view the whole Nissan system for 24 hours. (It includes all Nissan
vehicles for all model years, including service manuals, service bulletins,
training materials, etc.) They are provided as .pdf files.
I found this quite useful, as I have a Leaf another Nissan vehicle.
(To register, look for the "If you are a new visitor, register first" link, found on most pages.)
The manual is quite good, in particular it has good descriptions of how each of the
systems work, as well as the usual dissasembly/assembly & test instructions.
