The download I received was a complete waste of my money. Was not even close to what it was represented as. I thought I was getting a proper service repair manual. What I got was a collection of service bulletins. I sent an email to your company right after I looked through it requesting my money back. Have yet to hear a response. Terry Muich

It was much larger than i expected. 5 documents at 12k pages each. Its not something ill actually be able read but its easy enough to find what you need..
The Ford F250 manual is much easier to navigate at just over 8000 pages.
If i spend the money for Adobe Acrobat Professional ill be able to break it down into manageable bits.
Both manuals area great value for the money.

Schematics were not high resolution making the markings and names difficult to read when zoomed in. Improvement is needed. Otherwise it is a good document.

I wasn’t sure why I needed this to be a PDF, but it was apparent once I got it. It includes what would be thousands of pages if it were in print. The links take you to wherever you need to go in the text.

would rather have a maintenance manual. have a parts manual from parts vu company. only difference is that your parts manual has all together whereas the parts vu had to download the differsections individually.

Our original order was supposed to be for our 2014 Subaru Outback, yet the manual came up as Forester. We did have to purchase a new manual in order for them to send us the correct manual. We hope it will help us repair our Subaru.

Item as described quick delivery

Built around the 2008 RX 400h as Lexus actually configured it, this service and repair manual is matched to the year, the 3.3L V6 hybrid (3MZ-FE) and the driveline your RX left the assembly line with, so the clearances, torque figures and diagnostic trees you work from are the ones written for this car rather than a close approximation carried over from an adjacent model year.

Engines

  • 3.3L V6 HYBRID Naturally Aspirated

Trims

  • AWD
  • FWD

Known issues on the 2008 RX 400h. One recall is on federal record for this model year, and it covers the hybrid propulsion system inverter on certain RX 400h vehicles manufactured through December 2, 2008: the Intelligent Power Module inside the inverter module may contain transistors that have higher operating temperatures than the solder can support, and those transistors may be heat damaged. The vehicle may then enter a fail-safe/limp-home mode that limits drivability, and it is possible for the hybrid system to shut down while the vehicle is being driven, causing it to stall unexpectedly and increasing the risk of a crash. Owners have filed 127 complaints for the year, and no technical service bulletins are on record. The diagnostic and repair procedures behind the hybrid system and its inverter are here.

Whether you are tracing a fault in the hybrid system, testing the inverter, or working through a scheduled service interval, it keeps you on the OEM procedure and the specification Lexus set for this 2008 RX 400h.

NHTSA #13V39600004/09/2013Component: HYBRID PROPULSION SYSTEM: INVERTER

Toyota is recalling certain model year 2006-2010 Highlander hybrid vehicles manufactured February 16, 2005, through July 29, 2010; and model year 2006-2008 Lexus RX400h vehicles manufactured February 23, 2005, through December 2, 2008. The Intelligent Power Module (IPM) inside the inverter module may contain transistors that have higher operating temperatures than the solder can support and the transistors may be heat damaged by the solder. If this occurs, various warning lamps, including the malfunction indicator lamp, slip indicator light, brake system warning light, and master warning light, will be illuminated on the instrument panel.

Consequence

The vehicle may enter a fail-safe/limp-home mode that limits the drivability of the vehicle. It is possible that the hybrid system will shut down while the vehicle is being driven, causing the vehicle to stall unexpectedly, increasing the risk of a crash.

Remedy

Toyota will notify owners, and dealers will replace the IPM free of charge. Owners may contact Toyota at 1-800-331-4331. Vehicles that had their IPM replaced under recall 11V-342 are not affected by this campaign.

No service bulletins No technical service bulletins on file with NHTSA for the 2008 Lexus RX 400h.
