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.

October 20, '23 Our recent DEAD STOP! Whistle blower! Did you know that when the alternator goes out on a Lexus, that the car draws down energy from the battery to keep the car going? That's only for about a mile or so, then the car shuts down! You can't steer and THE ENGINE STOPS RUNNING and you have no power as you come to a dead stop, whether on the freeway, or one lane mountain pass road, where we would have been later. What would we have done? Scary! Luckily, our Lexus stalled on a city

Lexus never informed me or the dealer that the hatchback lift will fail if the weather is below 60 degrees. Sometimes even warmer.
