FAQQuestions about the GS 400 manual
Which GS 400 years does this manual cover?
Every year from 1998 to 2000 — 3 separate manuals, one per model year. Pick your year in the selector; the manual you receive is matched to that exact year, engine and trim.
Is this the OEM Lexus GS 400 manual or an aftermarket guide?
The OEM version. It carries the procedures, specifications, torque values and wiring diagrams Lexus published for the GS 400, organized by system — not a condensed aftermarket summary.
Does it include GS 400 wiring diagrams?
Yes. Full wiring diagrams are part of every GS 400 manual, alongside repair procedures, specifications and diagnostic information.
Why do some GS 400 years cost more?
Every GS 400 year is $34.99.
Is this a subscription?
No. One payment, and the manual is yours to keep — unlike per-vehicle subscriptions that renew every year.
How do I get the manual after purchase?
It is a digital manual — nothing ships. Access details arrive by email right after checkout, and you can use it on any device.
