State of vehicle. 2.4.1. For the test, the vehicle shall either be fitted with all the normal components and equipment included in its unladen kerb mass or be in such a condition as to satisfy this requirement so far as the components and equipment of concern to the passenger compartment and the distribution of the mass of the vehicle as a whole, in running order, are concerned. At the request of the manufacturer, by derogation from paragraph 5.1. of this Regulation, the test may be carried out with manikins in position, provided they do not at any time hinder the movement of the steering mechanism. The mass of the manikins shall not be taken into account for the purposes of the test. 2.4.2. If the vehicle is driven by external means, the fuel feed system shall be filled to at least 90 per cent of its capacity with a non-inflammable liquid having a density between 0.7 and 1. This requirement does not apply for Hydrogen as fuel. All the other systems (brake-fluid reservoirs, radiator, etc.) may be empty. 2.4.3. If the vehicle is driven by its own engine, the fuel tank shall be at least 90 per cent of a full load of fuel. All other reservoirs shall be filled to capacity. It shall be allowed by agreement between manufacturer and Technical Service to modify the fuel system so that an appropriate amount of fuel can be used to run the engine or the electrical energy conversion system. In such case, the fuel tank shall be filled to not less than 90 per cent of mass of a full load of fuel with a non-inflammable liquid of a density between 0.7 and 1. This requirement does not apply to Hydrogen fuel tanks. 2.4.4. Electrical power train adjustment 2.4.4.1. The RESS shall be at any state of charge, which allows the normal operation of the power train as recommended by the manufacturer. 2.4.4.2. The electrical power train shall be energized with or without the operation of the original electrical energy sources (e.g. engine-generator, RESS or electric energy conversion system), however: 2.4.4.2.1. By the agreement between Technical Service and manufacturer it shall be permissible to perform the test with all or parts of the electrical power train not being energized in so far as there is no negative influence on the test result. For parts of the electrical power train not energized, the protection against electrical shock shall be proved by either physical protection or isolation resistance and appropriate additional evidence. 2.4.4.2.2. In the case where an automatic disconnect is provided, at the request of the manufacturer it shall be permissible to perform the test with the automatic disconnect being triggered. In this case it shall be demonstrated that the automatic disconnect would have operated during the impact test. This includes the automatic activation signal as well as the galvanic separation considering the conditions as seen during the impact. 2.4.5. If the manufacturer so requests, the technical service responsible for conducting the tests may allow the same vehicle as is used for tests prescribed by other Regulations (including tests capable of affecting its structure) to be used also for the tests prescribed by this Regulation. 2.4.6. The steering wheel, if adjustable, shall be placed in the normal position indicated by the manufacturer or, failing that, midway between the limits of its range(s) of adjustment.

2.4.4. Electrical Electric power train adjustment
2.4.4.1. Procedures for SOC adjustment.
2.4.4.1.1. The RESS adjustment of SOC shall be conducted at any state an ambient temperature of charge20 ± 10 °C.
2.4.4.1.2. The SOC shall be adjusted according to one of the following procedures as applicable. Where different charging procedures are possible, REESS shall be charged using the procedure which allows yields the highest SOC:
(a) For a vehicle with a REESS designed to be externally charged, the REESS shall be charged to the highest SOC in accordance with the procedure specified by the manufacturer for normal operation until the charging process is normally terminated.
(b) For a vehicle with a REESS designed to be charged only by an energy source on the vehicle, the REESS shall be charged to the highest SOC which is achievable with normal operation of the power train as recommended vehicle. The manufacturer shall advise on the vehicle operation mode to attain this SOC.
2.4.4.1.3. When the vehicle is tested, SOC shall be no less than 95 per cent of SOC according to paragraphs 2.4.4.1.1. and 2.4.4.1.2. for ▇▇▇▇▇ designed to be externally charged and shall be no less than 90 per cent of SOC according to paragraphs 2.4.4.1.1. and 2.4.4.1.2. for ▇▇▇▇▇ designed to be charged only by an energy source on the vehicle. SOC will be confirmed by a method provided by the manufacturer.
