Mercedes-Benz EQS

Fuel Contamination Remediation Standards

⚠️ Mercedes-Benz EQS — Not applicable misfuel risk

Battery-electric variants have no petrol or diesel tank; contamination risk relates to other fluids (e.g. washer reservoir) rather than misfuel at the fuel filler.

If the engine was not started

Exterior decontamination only.

If the engine was started

Fuel cannot power EQS traction motor; focus on material and HV safety if fuel contacted electrics.

⚠️ Mercedes-Benz position — EQS

EQS has no fuel tank; Mercedes-Maybach EQS shares same EV architecture for energy storage.
