Opening and closing
The door windows are opened and closed
electrically. The switches for all door windows
are located on the driver’s door control panel.
The switches for the respective door windows
are located on the front passenger door and
on the rear doors.
i Operating the rear door windows from
the rear is not possible when you activate
the override switch (Y page 59).
GObserve Safety notes, see page 54.GWarning!
When opening or closing the door windows,
make sure there is no danger of anyone being
harmed by the opening/closing procedure.
The door windows are equipped with the
express operation and automatic reversal
function. If in express operation mode a door
window encounters an obstruction that
blocks its path, the automatic reversal
function will stop the door window and open
it slightly.
The door windows operate differently when
the switch is pulled and held. See the “Closing
when a door window is blocked” section in
this chapter for details.
The closing of the door windows can be
immediately halted by releasing the switch or,
if the switch was pulled past the resistance
point and released, by either pressing or
pulling the respective switch.
If a door window encounters an obstruction
that blocks its path in a circumstance where
you are closing the door windows by pressing
and holding button & on the SmartKey or
by pressing and holding the sensor surface
(vehicles with KEYLESS-GO) on an outside
door handle, the automatic reversal function
will not operate.
Activate the override switch when children
are riding in the back seats of the vehicle. The
children may otherwise injure themselves,
e.g. by becoming trapped in the door window
opening.
GWarning!
Do not keep any part of your body up against
the window pane when opening a window. The
downward motion of the pane may pull that
part of your body down between the window
pane and the door frame and trap it there. If
there is a risk of entrapment, release the
switch and pull it to close the window.
iYou can also open or close the door
windows using the SmartKey, see
“Summer opening feature” (Y page 99)
and “Convenience closing feature”
(Y page 100).
iAfter switching off the ignition or
removing the SmartKey from the starter
switch, you can operate the door windows
until you open the driver’s or front
passenger door. If no door was opened you
can operate the door windows for up to
5 minutes.

i The components and operating principles
of the audio system can be found on
( Y  page 137) and ( Y page 143).
The audio system is fitted with either a single
CD drive or a CD changer.
The single CD player and the CD changer can
play audio CDs as well as CDs with MP3 or
WMA files.
The available menu options will vary
depending on the equipment and the type of
CD.
Safety precautionsGWarning!
The single CD player and the CD changer are
classified as a Class 1 laser product. You must
not open the casing. There is a risk of
exposure to invisible laser radiation if you
open the casing, or if the casing is faulty or
damaged.
The single CD player and the CD changer do
not contain any parts that you are able to
maintain yourself. For safety reasons, all
maintenance work must be carried out by
qualified technicians.
GWarning!
In order to avoid distraction which could lead
to an accident, the driver should insert or
eject CDs with the vehicle at a standstill and
operate the audio system only if permitted by
road, weather and traffic conditions.
Bear in mind that at a speed of just 30 mph
(approximately 50 km/h), your vehicle is
covering a distance of 44 feet (approximately
14 m) every second.
General notes
i Audio CDs with copy protection are not
compatible with the CD audio standard and
therefore may not be able to be played by
the single CD player and/or the CD
changer. There may be playback problems
when playing copied discs.
There is a large variety of discs, disc-writing
software and writers available. This variety
means that there is no guarantee that the
system will be able to play discs that you
have written/copied yourself.
There may be playback problems if you use
CD-R or CD-RW type discs you have
compiled yourself with a storage capacity
of more than 700 MB. These CDs are not
compatible with currently applicable
standards.
