Frequently Asked Questions
Does this manual cover both the W140 sedan and C140 coupe?
Yes. The W140 sedan variants — S280, S300, S320, S350, S420, S500, and S600 — are fully covered, including short and long wheelbase configurations. The C140 coupe series, marketed as the CL420, CL500, and CL600 after the 1996 model year, is equally documented with coupe-specific body and trim procedures.
Which automatic transmissions are covered in detail?
The manual addresses all three 722-family automatics fitted to the W140/C140: the older 722.3 and 722.5 units found in early production cars, and the electronically controlled 722.6 five-speed introduced in the mid-1990s. Rebuild procedures, conductor plate replacement, and shift adaptation reset instructions are included.
Are wiring diagrams included for the climate control and ABS systems?
Full wiring diagrams are provided for all major electrical systems, including the dual-zone climate control, ABS/ASR, central locking vacuum circuit, power windows, and instrument cluster. Connector pinouts, ground locations, fuse assignments, and wire color codes are clearly identified throughout.
