SUNROOF

GENERAL DESCRIPTION

The sunroof (INALFA) is of the glass type with sunshade curtain and it can be distinguished from the previous one (WEBASTO) by the completely smooth outer deflector (rather than having three grooves).

The sliding mechanisms of the sunroof enable two different types of positioning:

  • a "concealed" position, by which it can be partially or completely opened, making it slide completely into the gap between the roof panel trim and the roof panel.
  • a "quarter-light" position, by which the roof is raised to allow air to escape from the passenger compartment but limits ventilation.

The sunshade is also housed, in the opening position, in the space between the roof panel trim and the roof panel. The sunroof is operated by a pushbutton (1) located on the front roof light; the type of resulting movement (closing/"quarter-light" opening or "concealed" opening) is caused by the profile of the cams machined on the runners and by the sliding of the runners inside the guides.

Sunroof control panel with pushbuttons A and B, and deflector 1.

The sunroof operating sequence is described in the following table:

Initial position Operation Position obtained
Completely open Press «A» Closed
Closed Press «A» Quarter-light
Quarter light Press «B» Closed
Closed Press «B» Completely open

The sunroof (see Figure) consists of an external glass (3), sliding on guides (2), an outside deflector (1) and the glass moving device.
