Buick 2007 Rendezvous - Manual (Page 169)

Sunroof
If the vehicle has a
sunroof, the switch to
operate it is located
on the headliner,
between the sun visors.
The sunroof switch will only work when the ignition
is ON or when the ignition is OFF and Retained
Accessory Power (RAP) is active. See Retained
Accessory Power (RAP) on page 129.
Notice: Opening the sunroof when the
luggage rack crossrails are not in the full-rear
position could cause damage to the sunroof
or luggage rack. Verify the luggage rack
crossrails are in the full-rear position before
opening the sunroof.
Press the rear of the switch to open the sunroof to
the vent position. The sunshade must be opened
by hand.
Press and release the rear of the switch a second
time to express-open the sunroof. The sunshade
will open with the sunroof. Press the switch in
either direction to stop it from moving. If the rear
of the switch is pressed and held, the
express-open operation will be overridden.
To close the sunroof, press and hold the front of
the switch.
