• Covers 2008 W204 sedans: C 230, C 300, and C 350, including standard, Sport, 4MATIC, and 4MATIC Sport versions, with U.S./Canadian applicability identified.
• Practical hints cover starter-battery removal and reinstallation, charging precautions, jump starting, emergency gear-selector unlocking, and fuel-filler-flap release.
• Replacement procedures address SmartKey batteries, wiper blades, and serviceable exterior bulbs, with separate halogen and Bi-Xenon lamp information.
• Sunroof and panorama-roof synchronization procedures are included, along with resetting the automatic exterior-mirror fold-in function.
• Tire coverage combines Minispare wheel mounting with separate restart procedures for TPMS (USA) and the Run Flat Indicator (Canada).
• Warning-lamp and multifunction-display tables explain possible causes, consequences, and suggested solutions for operating problems.

Shop Utility: Controls and Operating Checks

This Mercedes-Benz factory Operator’s Manual is a 509-page PDF, P/N 204 584 11 81, USA Edition A 2008, Order No. 6515 0614 13. It provides factory baseline data for routine checks and initial repair planning, but it is not a workshop repair manual. Internal engine/transmission overhaul procedures and circuit-level diagnostic information are outside its scope.

All C 230 versions are marked Canada-only, as are C 350, C 350 4MATIC, and C 350 4MATIC Sport. C 350 Sport is listed without that restriction. Optional equipment is identified separately rather than treated as standard on every car.

Manual and automatic transmission sections explain shift patterns, with Comfort/Sport programs and Limp-Home Mode covered for the automatic. Climate-control coverage distinguishes the dual-zone system from optional Canada-only 3-zone automatic climate control, including rear controls and residual engine heat. KEYLESS-GO is also marked Canada-only.

Instrument-cluster menus cover Service, Settings, lighting, and convenience functions. The audio chapter addresses Bluetooth phone setup and factory-setting restoration; detailed COMAND operation belongs to separate operating instructions.

Maintenance Indicators, Fuse Access, and Illustrated Procedures

Underhood guidance covers dipstick oil-level checks, coolant-level inspection, and washer-system filling. The maintenance chapter explains Service A/B reminders, viewing the next due date, and clearing a reminder. The service-indicator reset procedure is supplied separately through Mercedes-Benz service information. Scheduled maintenance work is detailed in the separate Maintenance Booklet.

Fuse sections show access to the passenger-compartment, engine-compartment, and trunk fuse boxes. The fuse-allocation/amperage chart is a separate in-vehicle document, stored in the passenger-compartment fuse box. This manual does not reproduce that chart or provide a relay-location map or electrical wiring diagrams.

Illustrated references include “Front lamps halogen-type” and “Tail lamp unit,” identifying bulb access points and carriers. The “Jacking up” views locate the wheel-change support brackets. Bi-Xenon bulb and LED replacement are referred to qualified service rather than presented as owner replacement work.

Engine, Fluid, and Wheel Specifications

Engine tables identify engine type 272 and model-specific 204-series codes, with displacement, output, and firing-order specifications. Electrical data include spark-plug identification, gap, and tightening specifications. Fluid-capacity tables cover engine lubrication, manual and automatic transmissions, and front and rear axles. Additional entries address steering, brakes, cooling, and washer systems.

The “Layout of poly-V-belt drive” is specifically labeled C 300/C 350 and identifies the tensioner and driven accessories. “Same size tires” and “Mixed size tires” tables distinguish wheel fitments, including AMG wheel options. Separate U.S. flexible-fuel coverage explains E85 identification by the fuel-flap label, switching fuels, and temperature-related starting behavior.

The 4MATIC warnings address transfer-case damage from one-axle towing or performance testing on a single-axle dynamometer. Battery precautions explain how disconnecting terminals with the engine running can damage the alternator and other electronics.

SRS, OCS, and Driving Safety Systems

Safety coverage describes the Supplemental Restraint System (SRS) and Occupant Classification System (OCS), including self-test and indicator behavior. A separate procedure addresses resetting activated head restraints, with inspection after a rear-end collision also specified.

ABS, BAS, EBP, and ESP, Adaptive Brake, and 4MATIC are explained through their operating behavior and limitations—not workshop test tolerances. Airbag repair and OCS calibration procedures are outside this publication’s scope.

Observe the documented SRS precautions. Restraint-system repair must be performed by qualified technicians; improper work can cause accidental deployment or leave the system inoperative.
