!!! Important !!! For vehicles equipped with a high-voltage on-board electrical system, all the following relevant information for the vehicle must be observed before starting work to assess safety after an accident, fire or problems with the high-voltage on-board electrical system!
Check
Danger
Risk of death when working on component parts and systems with U >= 30 V alternating voltage (AC) or U >= 60 V direct voltage (DC)
Do not touch damaged or defective live component parts and lines or non-insulated electrical connections and lines.
Risk of fire/risk of explosion due to short circuit and escaping oxyhydrogen gas. Risk of (burn) injury caused by caustic burns to eyes, skin and mucous membranes from battery electrolyte/mist, short circuit and arcing. Risk of poisoning caused by swallowing battery electrolyte or absorption of lead through the skin or body orifices. Risk of death due to voltage U >= 30 V AC and U >= 60 V DC.
No fires, sparks, open flames, or smoking. Wear acid-resistant gloves, clothing, and glasses. Pour battery acid only into suitable and appropriately marked containers.
General information on vehicles with high-voltage on-board electrical system and/or lithium-ion battery and/or gaseous-fuel drive system as well as personal protective equipment
Make sure that you have the required qualification for assessing the safety of the high-voltage on-board electrical systems.
Service Information: Qualification measures for working on high-voltage on-board electrical systems, lithium-ion batteries and gaseous fuel drive systems
The required Mercedes-Benz/smart specific qualification/instructions can also be obtained from Mercedes-Benz Global Training. Your MPC can inform you about whether further qualifications/instructions are required for any additional country-specific regulations and laws.
Do you have the required qualification?
If not, you may not assess safety on vehicles with a high-voltage on-board electrical system!
If the answer is yes, continue with operation step 2
