CLOSING POWER SHADE
Express Mode
Push the switch forward and release it within
one-half second and the shade will close
automatically from any position. If the sunroof is
completely closed the shade will close fully and
stop automatically. This is called “Express
Close”. During Express Close operation, any
movement of the switch will stop the shade.
NOTE:
If the sunroof is open, the shade will close to the
half-open position. Pushing the shade close
button again will automatically close both the
sunroof and shade completely.
Manual Mode
To close the shade, push and hold the switch in
the forward position. Any release of the switch
will stop the movement and the shade will
remain in a partially closed condition until the
switch is pushed again.
PINCH PROTECT FEATURE
This feature will detect an obstruction in the
closing of the sunroof during the Express Close
operation. If an obstruction in the path of the sunroof is detected, the sunroof will
automatically retract. Remove the obstruction if
this occurs.
NOTE:
If three consecutive sunroof close attempts
result in Pinch Protect reversals, Pinch Protect
will disable and the sunroof must be closed in
Manual Mode.
SUNROOF MAINTENANCE
Use only a non-abrasive cleaner and a soft cloth
to clean the glass panel. Periodically check for
and clear out any debris that may have
collected in the tracks.
IGNITION OFF OPERATION
NOTE:
The power sunroof switch can remain active
in Accessory Delay for up to approximately
10 minutes after the vehicle’s ignition is
placed in the OFF position. Opening either
front door will cancel this feature.
