9Q – 2 ROOF
DAEWOO M-150 BL2
DESCRIPTION AND OPERATION
ROOF
The roof is a one-piece painted metal unit which incorpo-
rates a single, solid headliner and two moldings, one on
each side of the vehicle’s roof.
The moldings, which enclose and hide the roof rail
seams, are serviceable as individual units.
The one-piece formed headliner, common to both the
notchback and the hatchback, consists of a molded sub-
strate covered with a foam-backed cloth facing. The
one-piece construction requires servicing the headliner
as a complete assembly.
MANUAL SUNROOF
The sunroof is
Intended to provide light and air through the roof of
the vehicle during the driving.
Built into the roof.
Made of glass.
SUN VISORS
The sun visors swing down or side in order to block out
glare. They also swing to the side when they are re-
leased from the support.
PASSENGER ASSIST HANDLE
There is a passenger assist handle for the front passen-
ger seat. Passengers can use these handles to assist in
keeping their balance over rough roads or during sharp
turns.
COAT HOOK
The coat hook is fastened to the headliner above the
left-hand rear passenger seat for Left–Hand Drive or
right hand rear passenger seat for Right–Hand Drive.
This position has a coat hook in the place of a passenger
assist handle.
