is nearest to midway between the foremost and rearmost positions; if this position is between two notches, the rearmost notch shall be used.
    5.5.2. The head restraint shall be adjusted such that its top surface is level with the centre of gravity of the dummy's head; if this is not possible, the head restraint shall be in the uppermost position.
    5.5.3. Unless otherwise specified by the manufacturer, the seat-back shall be set such that the torso reference line of the three-dimensional H point machine is set at an angle of 25 ± 1 towards the rear.
    5.5.4. All other seat adjustments shall be at the mid-point of available travel; however, height adjustment shall be at the position corresponding to the fixed seat, if the vehicle type is available with adjustable and fixed seats.  If locking positions are not available at the respective mid-points of travel, the positions immediately rearward, down, or outboard of the mid-points shall be used.  For rotational adjustments (tilt), rearward will be the adjustment direction which moves the head of the dummy rearwards.  If the dummy protrudes outside the normal passenger volume, eg. head into roof lining, then 1 cm clearance will be provided using:  secondary adjustments, seat-back angle, or fore-aft adjustment in that order.
    5.6. Unless otherwise specified by the manufacturer, the other front seats shall, if possible, be adjusted to the same position as the seat containing the dummy.
    5.7. If the steering wheel is adjustable, all adjustments are positioned to their mid-travel locations.
    5.8. Tyres shall be inflated to the pressure specified by the vehicle manufacturer.
    5.9. The test vehicle shall be set horizontal about its roll axis and maintained by supports in that position until the side impact dummy is in place and after all preparatory work is complete.
    5.10. The vehicle shall be at its normal attitude corresponding to the conditions set out in paragraph 4.3. above.  Vehicles with suspension enabling their ground clearance to be adjusted shall be tested under the normal conditions of use at 50 km/h as defined by the vehicle manufacturer.  This shall be assured by means of additional supports, if necessary, but such supports shall have no influence on the crash behaviour of the test vehicle during the impact.

    6. SIDE IMPACT DUMMY AND ITS INSTALLATION
    6.1. The side impact dummy shall comply with the specifications given in annex 6 and be installed in the front seat on the impact side according to the procedure given in annex 7 to this Regulation.
    6.2. The safety-belts or other restraint systems, which are specified for the vehicle, shall be used.  Belts should be of an approved type, conforming to Regulation No. 16 or to other equivalent requirements and mounted
