Warning!G
When opening or closing the tilt/sliding pan-
el, make sure that there is no danger of any-
one being harmed by the opening or closing
procedure.
The opening procedure of the tilt/sliding
panel can be immediately halted by releas-
ing the switch or, if the switch was moved
past the resistance point and released, by
moving the switch in any direction.
The closing procedure of the tilt/sliding
panel can be immediately halted by releas-

The panorama roof with power tilt/sliding
panel is made out of glass. In the event of an
accident, the glass may shatter. This may re-
sult in an opening in the roof.
In a vehicle rollover, occupants not wearing
their seat belts or not wearing them properly
may be thrown out of the opening.
Such an opening also presents a potential
for injury for occupants wearing their seat
belts properly as entire body parts or por-
tions of them may protrude from the pas-
senger compartment.
When leaving the vehicle, always remove the
SmartKey or SmartKey with KEYLESS-GO*
from the starter switch, take it with you, and
lock the vehicle. Do not leave children
unattended in the vehicle, or with access to
an unlocked vehicle. A child’s unsupervised
access to a vehicle could result in an acci-
dent and/or serious personal injury.
!To avoid damaging the seals, do not trans-
port any objects with sharp edges which can
stick out of the tilt/sliding panel.
Do not open the tilt/sliding panel if there is snow
or ice on the roof, as this could result in malfunc-
tions.
Depending on vehicle production date your vehi-
cle may be equipped with a crank to open or
close the tilt/sliding sunroof manually should an
electrical malfunction occur (
page 674).
