Opening and closing Ð from the insideYou can operate the central locking
system with this button when the
driver's door is closed. The doors and
liftgate are unlocked or locked only.
However, the anti-theft system is not
activated. Also, the fuel Þller door
remains unlocked to allow refueling.
If only the driver's door was
unlocked from the outside and
you press the button
>all other doors, the tailgate/liftgate
and the fuel filler door will be
unlocked when the driver's door is
opened
>the driver's door will be locked again
when it is closed.< 530de220
To unlock and open the doors >Either unlock the doors together with
the button for the central locking
system and then pull the door handle
above the armrest
or
>pull the release handle for each door
twice: the first pull unlocks the door,
and the second one opens it.
To engage the locks >Use the central locking button to lock

>press down the individual safety lock
buttons. The fuel filler door remains
unlocked. As an added design
feature to prevent the driver from
being inadvertently locked out of the
vehicle, the driver's safety lock
button will not engage as long as the
door is open.
When the vehicle is moving, do
not lock the doors with the safety
lock buttons. Doors locked in this
manner would not unlock automatically
in the event of an accident.
Since passengers or animals remaining
in the vehicle might be able to lock the
doors from the inside, take the vehicle's
keys with you so that the vehicle can be
opened again from the outside at any
time.<

Liftgate TailgateTo close You can pull the liftgate down by
placing both hands in the handle
recesses (arrows).
To avoid injuries, be sure that the
travel path of the liftgate is clear
when it is closed, as with all closing
procedures.< 530us017
Operate the vehicle only when
both gates are completely closed.
Otherwise, exhaust fumes could pene-
trate the interior of the vehicle. Should it
be absolutely necessary to operate the
vehicle with an open gate:
>Close all windows. Shut the sliding/
tilt sunroof
>Increase the air supply for the air
conditioner or automatic climate
control to a high level, refer to
page 104 or 108.<
To openPress the button:
You can fold the tailgate down.
When opened, the tailgate can
accept loads of up to 440 lbs
(200 kg). When the vehicle is parked,
you may utilize the tailgate as a seat or
as a loading platform for luggage or
recreation gear, for example.< 530de246

Alarm system The concept The vehicle alarm system responds:
>When a door, the hood, or the liftgate
is opened
>To movement inside the vehicle (inte-
rior motion sensor)
>To variations in the vehicle tilt angle
such as occur during attempts to
steal the wheels or tow the vehicle
>To interruption of battery voltage.
The system responds to unauthorized
vehicle entry and attempted theft by
simultaneously activating the following:
>Sounding an acoustical alarm for
30 seconds
>The hazard warning flashers are acti-
vated for approx. five minutes
>The high beams flash on and off in
the same rhythm.
To arm and disarm the alarm
system When the vehicle is locked or unlocked
with the key or the remote control, the
alarm system is also simultaneously
armed or disarmed.
You can have different acknowl-
edgment signals set to confirm
system arming and disarming.<
You can still open the liftgate after the
system has been armed by pressing the
button of the remote control, refer to
page 33. When you close the liftgate, it
is secured again.
Indicator lamp displays>The indicator lamp below the interior
rearview mirror flashes continuously:
the system is armed
>The indicator lamp flashes during
arming: the door(s), the hood or lift-
gate are not completely closed. Even
if you do not close the alerted area,
the system begins to monitor the
remaining areas, and the indicator
lamp flashes continuously after
10 seconds. However, the interior
motion sensor is not activated
>If the indicator lamp goes out when
the system is disarmed: no manipula-
tion or attempted intrusions have
been detected in the period since the
system was armed530us018

Electric power windows 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 windows,
press the switch beyond the pressure
point.
Remove the key from the ignition
lock and close the doors when
you leave the vehicle so that children
cannot operate the power windows and
possibly injure themselves.<
For the convenience mode via the door
lock or the remote control, refer to
page 31 or page 33. 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 (with very thin
objects, for instance).
You can override this safety feature by
pulling the switch beyond the pressure
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 ensure
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 vehicle. Never leave the
keys in the vehicle with unsupervised
children. Never place anything that
could obstruct the driver's vision on or
next to the windows.<
Safety switch With the safety switch, you can prevent
the rear windows from being opened or
closed via the switches in the rear
passenger area (by children, for
example). You can also prevent adjust-
ments of the power rear-seat backrests
from the rear passenger area, refer to
page 48.
Press the safety switch whenever
children are riding in the rear of
the vehicle. Careless use of the power
windows can lead to injury.< 530us209

Sliding/tilt sunroof with glass moonroof
*
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
disable this safety feature by pressing
the switch beyond the pressure point
and holding it.<
Power lossAfter 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 fully
2. Press and hold the switch for approx.
twenty seconds. 530de248
Manual operationIn the event of an electrical malfunction,
you can operate the sliding/tilt sunroof
manually:
1. Open the glasses compartment, refer
to page 118
2. Insert the Allen wrench from the
vehicle tool kit (refer to page 152) in
the opening provided and turn the
sliding/tilt sunroof in the desired
direction. 530us124
