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.

Everything in this service and repair manual is keyed to the 2003 Lexus RX 300 as it left the assembly line — the 3.0L V6 (1MZ-FE), in either AWD or FWD form — so the clearances, torque values and procedures you work to are the ones Lexus published for this model year, not figures carried over from an adjacent one.

Known issues on the 2003 RX 300. Three recalls are on federal record for this model year, and all three cover replacement parts sold for the vehicle. The first covers back glass sold as replacement equipment, which fails to conform to the automotive glazing material requirements of Federal Motor Vehicle Safety Standard No. 205 — a standard whose purpose is to reduce injuries resulting from impact to glazing surfaces. The other two cover exterior lighting: one for certain CK Motorsports combination headlights, clear corner, bumper and side marker lights, the other for certain Pro-A Motors corner lamps, turn signals and headlights. In both cases, some combination lamps not equipped with amber side reflectors fail to conform to Federal Motor Vehicle Safety Standard No. 108, and without the amber reflectors the vehicle will be poorly illuminated, possibly resulting in a vehicle crash without warning. Owners have filed 30 complaints for the year, and no technical service bulletins are on record. The removal, installation and diagnostic procedures behind the glass and exterior lighting systems are here.

From a rear glass replacement to a lighting fault or a scheduled service interval, it keeps you on the manufacturer procedure and the correct specification for this 2003 RX 300.

THE TRANSMISSIONS IN LEXUS RX300 MODELS ARE UNSAFE. THE TRANSMISSION IN MY RX300 HAD TO BE REPLACED AT 70,000 MILES AND AGAIN AT 120,000 MILES. LEXUS IS NOT STANDING BEHIND THEIR PRODUCT. THERE HAVE BEEN NUMEROUS COMPLAINTS ABOUT THE TRANSMISSION IN THE RX300 MODEL. LEXUS WILL NOT ACKNOWLEDGE THIS DEFECT. ALSO, I WAS MISLED AT THE DEALERSHIP THE FIRST TIME THEY REPLACED THE TRANSMISSION. I WAS ASSURED THAT THE TRANSMISSION WAS NOT "REFURBISHED", WHEN, INDEED, IT IS NOT A NEW TRANSMISSION.
