Frequently Asked Questions
Is the X167 chassis platform fully covered, including Maybach-exclusive components?
Yes. The manual addresses both the standard X167 GLS architecture and the Maybach-specific content, including extended rear cabin electronics, executive seating controls, Burmester 3D audio system wiring, and the unique Maybach body trim procedures not found in the standard GLS service documentation.
Does this manual cover the 48V EQ Boost mild hybrid system?
Yes. Complete service procedures are included for the EQ Boost integrated starter-generator, the 48V lithium-ion battery module, and the belt-driven starter unit. Diagnostic flowcharts and DTC resolution steps for hybrid-related fault codes are detailed throughout the electrical and engine management sections.
Are E-Active Body Control suspension diagnostics included?
Yes. The suspension section covers the full E-Active Body Control hydraulic system fitted to the GLS600 4Matic, including strut removal and installation, hydraulic pressure testing, ride-height sensor recalibration, and pump assembly diagnostics – procedures that are critical given known oil leak concerns on early X167 units.
What format is the manual?
The manual is delivered as a PDF file. It is fully searchable and compatible with Windows, Mac, iOS, and Android devices. Individual pages or complete chapters can be printed for shop use, and all diagrams are reproduced in high resolution.
