Frequently Asked Questions
Does this manual cover the high-voltage PHEV battery system on the GLC300e?
Yes. The software includes complete service procedures for the plug-in hybrid battery pack, including safe high-voltage isolation steps, cooling circuit maintenance, and battery module diagnostics — critical content not found in generic third-party guides.
What chassis code does this GLC300e use?
The 2020–2022 GLC300e 4MATIC rides on the X253 platform, the same architecture used across the GLC-Class range. This manual covers all X253 GLC300e variants sold in North America during this production window.
Are wiring diagrams for the charging and MBUX systems included?
Yes. Full high-voltage hybrid schematics, AC/DC charging circuit diagrams, MBUX infotainment wiring, ADAS sensor circuits, and complete fuse/relay box layouts with pin assignments are all included.
What format is the manual?
This product is dealer-level interactive software, not a static PDF. It runs on Windows and features a searchable database, exploded-view component locators, built-in torque specifications, and integrated diagnostic routines — the same toolset used at authorized Mercedes-Benz dealerships.
