2009 Mercedes-Benz C-Class C 250, C 300, C 350, C 63 AMG Operator's Manual (P/N 204 584 52 81)

This 2009 Mercedes-Benz C-Class Operator's Manual, P/N 204 584 52 81, covers the C 250, C 300, C 350 and C 63 AMG, including the listed 4MATIC and Sport variants and U.S./Canadian equipment differences.

• Restraints and safety: SRS, Occupant Classification System, BabySmart, child restraints, and NECK-PRO operating information and reset guidance.

• Driving systems: ABS, Adaptive Brake, ESP, 4MATIC, cruise control, and the C 63 AMG's ESP SPORT and ESP OFF modes.

• Controls and synchronization: SmartKey, KEYLESS-GO, memory and non-memory seat controls, power windows, and conventional or panorama-roof synchronization.

• Audio and communication: Bluetooth phone authorization, CD/MP3 operation, multifunction steering-wheel menus, and Tele Aid functions.

• Owner maintenance: Engine-oil and coolant checks, approved-fluid tables, tire-pressure monitoring, and ASSYST PLUS service reminders.

• Breakdown procedures: Emergency unlocking, automatic-selector release, bulb and wiper replacement, wheel changes, jump-starting, towing, and fuse-box access.

The manual is suited to owners who need operating instructions and illustrated routine-care guidance; specialist mechanical repair calls for separate service literature.

Safety Systems and Dashboard Troubleshooting

The restraint sections distinguish the U.S. Occupant Classification System (OCS) from Canada's BabySmart air bag deactivation system. Their self-test and passenger-air-bag indicator explanations apply to the respective installed system. SRS work is reserved for qualified technicians.

The Practical hints tables connect instrument-cluster warnings and multifunction-display messages with possible causes, consequences and responses. For example, the ABS entries distinguish insufficient supply voltage from a persistent malfunction, helping an owner interpret a warning before arranging further diagnosis.

C 63 AMG coverage explains its stability-control modes, AMG menu and RACETIMER. These sections describe operating behavior and system limitations.

Cabin Controls, Audio and Climate Functions

Illustrated instrument cluster, center console and door control panel layouts distinguish different equipment configurations. The window and roof sections explain synchronization after operating problems, including the panorama panel and its front roller sunblind.

The audio chapter covers Bluetooth device authorization, phonebook functions and CD/MP3 settings. Full COMAND operation belongs to separate operating instructions; this manual explains the related dashboard menus. Tele Aid descriptions depend on the vehicle's equipment and service activation.

Dual-zone climate-control instructions cover defrosting, recirculation and air distribution, with U.S./Canadian control-panel differences.

Routine Care and Roadside Procedures

Engine-compartment illustrations support oil, coolant, brake-fluid and washer-fluid checks. The tire sections distinguish U.S. Advanced TPMS from Canada's tire pressure loss warning system and explain their respective restart procedures.

ASSYST PLUS coverage explains viewing and dismissing service reminders. Maintenance-indicator reset instructions for service facilities are in separate maintenance literature, while scheduled maintenance work is detailed in the Maintenance Booklet.

The manual describes releasing an automatic selector locked in Park during an electrical fault and resetting activated NECK-PRO head restraints. It calls for a Mercedes-Benz Center check of the restraints after a rear-end collision.

Bulb illustrations identify halogen, Bi-Xenon and rear-lamp arrangements, with replacement procedures for the specified owner-serviceable bulbs. High-voltage Xenon bulb and lamp repairs are directed to qualified technicians.

Fuse-box views show access in the passenger compartment, trunk and engine compartment. The fuse allocation chart is a separate vehicle item stored with the tool kit; this PDF does not reproduce that chart or provide wiring schematics.

The 4MATIC cautions explain how unsuitable dynamometer testing can damage the brakes or transfer case. The jump-start section warns that incorrect connections can damage vehicle electronics.

Selected Oil Capacities and AMG Oil Requirements

These examples are a small selection from the manual's fluid and lubricant data.

For the C 350, the engine-with-filter capacity is 8.5 US qt (8.0 l); the C 350 4MATIC entry lists 7.4 US qt (7.0 l).

The approved-oil table specifies MB sheet 229.5 for the C 63 AMG, with a restriction to SAE 0W-40 or SAE 5W-40. That qualification matters when choosing oil for the AMG engine.
