Your Mercedes S-Class First Check: A Purchaser’s Essential Checklist

The Mercedes-Benz S-Class is more than just a car; it’s a statement of success, comfort, and advanced technology. When you purchase one, whether new or pre-owned, an initial, comprehensive check is your key to unlocking its full potential and ensuring lasting satisfaction. This process helps you familiarize yourself with your vehicle’s features, identify any potential immediate concerns, and solidify your informed purchase decision.

Blind Spot Monitoring: Verify the warning lights in the mirrors activate.
Parking Assist/360 Camera: Test the sensors and camera views for accuracy and responsiveness.
Dashboard and Warning Lights:
Initialization: Upon turning the ignition on, all warning lights should illuminate briefly and then extinguish. Any persistent warning lights (check engine, ABS, airbag, etc.) need immediate investigation.
Digital Displays: Ensure all digital screens (instrument cluster, central display) are functioning correctly without flickering or distortion.
Keyless Go/Remote Functions: Test all key fobs for door locking/unlocking, trunk opening, and remote start functionality.

5. Documentation and Service History (Crucial for Pre-Owned S-Class)

For a pre-owned S-Class, thorough documentation is as important as the mechanical inspection.

Service Records: Review the complete service history. Look for regular maintenance performed at authorized Mercedes-Benz dealerships or reputable specialists. This indicates good care and can highlight recurring issues if any.
Vehicle History Report (VHR): Confirm findings from the VHR (e.g., from a service like Carfax or AutoCheck) match the vehicle’s current condition and the provided service records. Look for accident history, title issues (salvage, flood), and odometer discrepancies.
Owner’s Manual & Literature: Ensure all original manuals, warranty information, and tool kits are present.
Title and Registration: Verify the paperwork is clean, accurate, and properly transferred.
