Electric power windowsOpen and close windowsFrom ignition key position 1:
>Depress the rocker switch until you
feel resistance:
The window continues moving for as
long as you maintain pressure on the
switch.
>Press the rocker switch beyond the
resistance point:
The window moves automatically.
Press the switch a second time to
stop the window.390de055
After the ignition has been switched off:
>You can still operate the windows as
long as neither of the front doors has
been opened. To open the window,
press the switch beyond the resis-
tance point.
Remove the key from the ignition
when you leave the vehicle, so
that children cannot operate the power
windows and possibly injure them-
selves.<
For the convenience mode via the door
lock or the remote control, refer to
pages 38 or 40.Safety featureA contact strip is integrated into the
inner side of each of the upper window
frame sections. If pressure is exerted
against this contact strip while a
window is being raised, the system
will respond by stopping the window
and then retracting it a small distance.
Despite this safety feature, be
extremely careful that the closing
path of the window is not obstructed
whenever it is closed. Otherwise, an
object might not touch the contact strip
in some situations (very thin objects, for
instance).
You can override this safety feature by
pressing the switch beyond the resis-
tance point and holding it.
Because the power windows are sealed
at high pressure to prevent wind noise
when closed, a powerful motor is
required for efficient closing. When
closing the windows, always be sure
that they are not obstructed in any way.
Unsupervised use of these systems can
result in serious personal injury.
Remove the ignition key to deactivate
the electric power windows whenever
you leave the car. Never leave the keys
in the vehicle with unsupervised chil-
dren.
Never place anything that could
obstruct the driver's vision on or next
to the windows.<

Electric power windows Sliding/Tilt sunroof
*
Safety switchWith the safety switch, you can prevent
the rear windows from being opened or
closed via the switch in the rear pas-
senger area (by children, for example).
Press the safety switch whenever
children are riding in the rear of
the vehicle. Careless use of the power
windows can lead to injury.< 390de131
To prevent injuries, exercise care
when closing the sliding/tilt sun-
roof and keep it in your field of vision
until it is shut.
Before leaving the car, switch off the
electric sunroof mechanism by taking
out the ignition key. Do not leave chil-
dren unattended in the vehicle with ac-
cess to vehicle keys. Use of the key can
result in starting of the engine and op-
eration of vehicle systems such as
power sunroof, etc. Unsupervised use
of these systems can result in serious
personal injury.<
You can avoid pressure or drafts in the
passenger compartment when the sun-
roof is open or lifted by keeping the air
vents in the instrument panel open and
increasing the air supply as required.
Refer to pages 108 or 114.
If the sunroof is completely open, air
disturbances may be caused in the ve-
hicle when you are driving at higher
speeds. Close the roof as far as is nec-
essary until this natural phenomenon
ceases.
For the convenience mode via the door
lock or the remote control, refer to
page 38 or 40.
Lifting – opening – closingFrom ignition key position 1, press the
switch or slide it to the desired direction
until you feel resistance.
When lifting, the headliner retracts
several inches.
If the sliding/tilt sunroof is up, then
the headliner cannot be closed.<
After the ignition has been switched off,
you can still operate the sliding/tilt sun-
roof as long as neither of the front
doors has been opened.390de636

Sliding/Tilt sunroof
*
Automatic
* opening and closing
Press the appropriate end of the control
switch past the resistance point and
then release it.
Other automatic operations are:
>With the sunroof open, press the
switch briefly toward "Lift:" the sun-
roof automatically extends to its fully
raised position.
>With the sunroof lifted, press the
switch briefly toward "Open:" the
sunroof automatically opens all the
way.
Pressing the switch again briefly stops
the motion.Safety featureIf the sliding/tilt sunroof encounters
resistance at a point roughly past the
middle of its travel when it is closing,
the closing cycle is interrupted and the
sliding/tilt sunroof will open again
slightly.Despite this safety feature, be
extremely careful that the closing
path of the sunroof is not obstructed
whenever it is closed. Otherwise, trig-
gering the closing-force limitation may
not be ensured in some situations (with
very thin objects, for instance). You can
override this safety feature by pressing
the switch beyond the resistance point
and holding it.<
Sliding/tilt sunroof with glass
moonroof
*
The options and control procedures are
essentially the same as those previ-
ously described for the sliding/tilt sun-
roof. In order to open the raised roof,
press the control switch towards
"Open" until the roof has reached the
desired position.
The headliner insert slides back some-
what when you raise the sunroof. When
the sunroof is opened the headliner
retracts with it. The headliner will then
automatically remain in its retracted
position, but can be repositioned as
desired.
Power loss or malfunctionAfter interruptions in the electrical
supply (when the battery is discon-
nected, for instance), the sunroof may
only lift. To reinitialize the mechanism:
1 Raise the sliding/tilt sunroof all
the way.
2 Press and hold the switch for
approx. twenty seconds.
In the event of an electrical malfunction,
you can also operate the sliding/tilt
sunroof manually. Refer to page 198.390de637

For maximum safety, please comply
with the following instructions when ad-
justing a seat:
Never try to adjust your seat while
operating the vehicle. The seat
could respond with unexpected move-
ment, and the ensuing loss of vehicle
control could lead to an accident.
Wear the safety belt firmly against your
body at all times. In the event of a fron-
tal impact, a loose lap belt could slide
over your hips, leading to abdominal
injury. In addition, the safety belt's
restraint effectiveness is reduced if the
belt is worn loosely.
Never ride with the backrest reclined to
an extreme horizontal angle (especially
important for front passengers to
remember). Keep the backrest relatively
upright to minimize the risk of "sliding
under" the safety belt and sustaining
injury in an accident.
Do not slide the seats to the rear
when the vehicle is at an extreme angle
(on garage ramps or steep slopes, for
instance), to prevent the shoulder
strap's automatic height adjustment
mechanism from disengaging.<
Correct sitting postureTo reduce strain on the spinal column,
sit all the way back in the seat and rest
your back fully against the backrest.
The ideal sitting posture is achieved
with your head extending from your
spine in a straight line.
For long-distance driving, you may wish
to increase the backrest tilt-angle
slightly to reduce muscular tension.
Please remember that you should
always remain able to grasp the entire
periphery of the steering wheel without
straightening your arms.1 Tilt angle (only driver's side)
2 Forward/backward adjustment
3 Cushion height
4 Backrest angle
5 Head restraint height
Adjust the angle of the head restraints
by tilting the head restraint, refer to
page 53.
Read and comply with the adjust-
ment instructions in the previous
column. Failure to do so can result in
diminished personal safety.<

Head restraints reduce the risk
of spinal injury in the event of an
accident.
Adjust the head restraint so that its
center is approximately level with your
ears.
Leave the center rear head restraint in
the fully-lowered position at all times,
since pulling it out limits its function.<390de065
