    • Note: The passenger airbag could be deactivated via the vehicle’s SRS (Supplemental Restraint System) control module to accommodate child seats.

    - Seatbelt Pretensioners and Load Limiters
    All seating positions were equipped with three-point seatbelts featuring pyrotechnic pretensioners to tighten belts instantly during a collision. Load limiters in the shoulder belts reduced the risk of upper-body injuries by allowing controlled belt elongation.

    Active Safety Systems: Electronic Stability and Traction Control

    The W203’s active safety suite was anchored by Electronic Stability Program (ESP), a system that dynamically adjusted braking and throttle to prevent loss of control. Below is a step-by-step breakdown of its operation:

    - ESP Functionality Overview
    ESP monitored yaw rate (vehicle rotation), lateral acceleration, and wheel-speed sensors to detect understeer or oversteer. If a deviation from the driver’s intended path was detected, the system intervened through:
    1. Selective Wheel Braking
    Individual wheel brakes were applied to specific tires to realign the vehicle’s trajectory. For example, if the rear wheels lost traction (oversteer), the system would brake the rear outer wheel to stabilize the vehicle.
    2. Engine Power Reduction
    The throttle was modulated or briefly cut to reduce wheelspin, particularly during acceleration on slippery surfaces.
    3. Dynamic Traction Control (DTC)
    A subset of ESP, DTC prevented wheel lockup during acceleration by adjusting engine torque distribution and applying targeted brake pulses.

    - Integration with ABS and Brake Assist
    ESP worked in conjunction with the Anti-lock Braking System (ABS) to maintain steering control during hard braking. The Brake Assist feature automatically applied maximum braking force if the driver stomped the pedal, reducing stopping distances in emergency situations.

    - Hill Start Assist
    An optional feature that prevented rollback when starting on inclines by applying light brake pressure until the driver released the brake pedal and depressed the accelerator.

    Crash Test Ratings and Safety Implications

    The 2004 C-Class underwent rigorous crash testing, with results that reflected Mercedes-Benz’s commitment to safety. Key evaluations include:

    How do I perform a service reset on a 2004 Mercedes C-Class?

    To reset the service indicator, turn the ignition to "position 1" (accessories), hold the trip reset button (behind the clock) for 10 seconds, then release. Some models may require a scan tool (like Mercedes Star Diagnostic) if the method fails. Always complete the recommended service interval to avoid warning lights.

The dashboard is ergonomic, though some find the center console buttons small.
