FAQQuestions about the CLS400 manual

Which CLS400 years does this manual cover?

Every year from 2015 to 2018 — 4 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 Mercedes-Benz CLS400 manual or an aftermarket guide?

The OEM version. It carries the procedures, specifications, torque values and wiring diagrams Mercedes-Benz published for the CLS400, organized by system — not a condensed aftermarket summary.

Does it include CLS400 wiring diagrams?

Yes. Full wiring diagrams are part of every CLS400 manual, alongside repair procedures, specifications and diagnostic information.

Why do some CLS400 years cost more?

Every CLS400 year is $40.99.

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.
