Technical characteristics





Sliding/removable roof

Exact adjustment of a sliding roof is a condition of its faultless functioning. But detailed descriptions would be beyond this management. If at a sliding roof the heavy course, is made greasing (the head Smazka of all details). If the sliding roof does not move at all, it is necessary to check the corresponding automatic switch (the head the Electrotechnical equipment). The control unit of a sliding roof on a support with additional relays cannot be checked by own forces.

Not tight sliding roof

The reason of leakage of a sliding roof is covered in the got littered drain pipes which are established on one on each of four corners of a box of a sliding roof. Principle of work: water can get into a box of a sliding roof, but it has to flow down.

  • Both back drain openings are remote even at the roof shifted back (light a pocket small lamp in a box of a sliding roof).
  • Forward drain hoses come to an end at height of the lower hinge of a forward door. Both back hoses come to an end under lateral faces of a rear bumper (take out lateral face from an arm.
