2-20 Keys, Doors, and Windows
Express Window Operation
This feature allows the window to
automatically open or close fully.
To activate express-down, press
the switch fully to the second
detent and release.
To activate express-up, pull the
switch fully to the second detent
and release.
To stop window movement,
press or pull the switch briefly.
Obstacle Detection
This feature is active during
express-up movements in ON/RUN/
START, or when the engine is off
and RAP is active. Obstacle
detection also works with RAP when
the switch is held up.
If the window encounters an object
during closing, it will stop and open
to a predetermined distance.
Conditions such as severe cold or
ice may cause the window to
auto-reverse. The window will return
to normal operation once the
condition or object is removed.
If conditions prevent a window from
closing and the window continues to
auto-reverse, it is possible to close
the window while in ON/RUN by
holding the window switch in the
first or second detent until the
window is closed.
Window Operation with
Convertible Top
Windows automatically lower fully
when the convertible top is lowered
or raised. See Convertible Top on
page 2-25. To raise the windows,
pull the switch to the second detent
and release.
Window Indexing
Indexing automatically lowers the
window a small amount when the
door is opened. When the door is
closed, the window will raise to its
full up position. If either window
does not index properly, it could be
due to loss of power. Before
returning to the dealer for service,
perform the window indexing reset
procedure.
Window Indexing and
Express-Up Reset
Window indexing may be required if
the vehicle battery has been
recharged or disconnected, or is not
working. Express-up and the
convertible top will not function until
the windows are reset. After battery
power is restored, a message
displays in the Driver Information
Centre. See Driver Information
Centre (DIC) on page 5-25.
Once power is restored:
1. Close the doors.
2. Start the vehicle.
3. Hold the window switch up to the
fully closed position.
