Luggage compartment Floor panelTo raise and secure the floor panel, lift
it by the ring and hook it into the rubber
seal of the run-off gutter with the
hanger (arrow).460de106
Floor matYou can turn the floor mat over if re-
quired (for transporting soiled objects
for instance). The rubberized side may
be washed. It reduces movement of ob-
jects placed on it.460de180
The fittings at the corners of the lug-
gage compartment provide you with a
convenient means of attaching luggage
nets
* and flexible straps for securing
suitcases and luggage.
Refer also to "Cargo loading" on
page 99.

Alarm system
*
The conceptThe vehicle's alarm system responds:
>When a door, the hood or the lug-
gage compartment lid is opened
>To movement inside the vehicle
(interior motion sensor)
>To a change of the vehicle's tilt Ð if
someone attempts to steal the wheels
or tow the vehicle without authoriza-
tion, for example
>If there is an interruption of battery
voltage.
The alarm system signals unauthorized
access to the vehicle or an attempted
theft in different ways:
>Sounding an acoustical alarm for
30 seconds
>The hazard warning flashers are acti-
vated for approx. five minutes.
To activate and deactivate the
alarm systemWhen the vehicle is locked or unlocked
by using a key or with the remote con-
trol, the alarm system is also simulta-
neously armed or disarmed.
The interior motion sensor is activated
approx. 30 seconds after you have fin-
ished locking the car.
If the alarm system has been armed
correctly, the hazard warning flashers
flash once. An acoustic warning signal
sounds at the same time.
You can have different acknow-
ledgment messages set to confirm
arming and disarming.<
You can also open the luggage com-
partment lid when the system is armed
by pressing button 3 of the remote con-
trol (refer to page 37). When it is closed,
the lid is once again secured.
Indicator lamp displaysThe indicator lamp is located under the
interior rearview mirror.
>When the indicator lamp flashes con-
tinuously: The system is armed.
>If the indicator lamp flashes during
arming of the system: The door(s),
the hood or luggage compartment lid
are not completely closed. Even if
you do not close the alerted area, the
system begins to monitor the remain-
ing areas, and the indicator lamp
flashes continuously after 10 sec-
onds. However, the interior motion
sensor is not activated.
>If the indicator lamp goes out when
the system is disarmed: No manipu-
lation or attempted intrusions have
been detected in the period since the
system was armed.460de105

Alarm system
*
>If the indicator lamp flashes for
10 seconds when the system is dis-
armed: An attempted entry has been
detected in the period since the sys-
tem was armed.
Following triggering of an alarm, the in-
dicator lamp will flash continuously.Avoiding an unintentional alarmThe tilt alarm sensor and interior motion
sensor may be switched off at the same
time. You can do this to prevent a false
alarm from being triggered (in garages
with elevator ramps, for instance), or
when the vehicle is transported by
trailer or train:
Lock the vehicle twice (= arm the sys-
tem). Press button 2 on the remote con-
trol twice in succession or lock the
vehicle twice with the key (refer to
page 36).
The indicator lamp lights up briefly and
then flashes continuously. The tilt alarm
sensor and the interior motion sensor
are deactivated as long as the system is
armed.
Interior motion sensorThe transmitter and receiver of the inte-
rior motion sensor are located in a trim
panel in the vehicle's roof.
In order for the interior motion sensor to
function properly, the windows and
sliding/tilt sunroof must be completely
closed.
However, you should switch off the inte-
rior motion sensor (see previous column
under the heading "Avoiding an unin-
tentional alarm") if you wish to leave the
windows or sliding/tilt sunroof open.460de159
The tilt sensor and interior motion
sensor are deactivated if the con-
venience closing mode for the windows
and the sliding/tilt sunroof is interrupted
within the first 10 seconds and then
reinitiated. If this happens, you must
disarm the system and then re-arm it.<

Electric power windowsOpen and close the windowsIn ignition key position 1 or 2:
>Depress the switch until you feel
resistance:
The window will continue to open as
long as you hold the switch.
>Press the switch briefly past the pres-
sure point:
The window will automatically open
completely. Pressing the switch
again briefly stops the opening cycle.
You can close windows in the same
manner by pulling the switch.460de013
Separate switches are located under
windows in the rear passenger area.
After the ignition has been switched off:
You can still operate the power win-
dows for up to 15 minutes, as long as
neither of the front doors has been
opened.
Remove the key from the ignition
key and close the doors when you
leave the vehicle, so that children can-
not operate the power windows and
possibly injure themselves.<
For the convenience operating mode
with the door lock or remote control,
refer to page 34 or 35.
Safety feature A contact strip is located on the inside
upper frame of each of the windows. 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 ex-
tremely careful to ensure that the
closing path of the window is not ob-
structed. Otherwise, an object might
not touch the contact strip in some situ-
ations (very thin objects, for instance).
You can disable this safety feature by
pressing the switch beyond the resis-
tance point and holding it.<

Safety switch You can use the safety switch to deacti-
vate the rear power window switches
(when children are in the rear seats, for
instance).
Press the safety switch whenever
children are riding in the rear of
the vehicle. Careless use of the power
windows can lead to injury.<460de014
Exercise care when closing the
sliding/tilt sunroof and keep it in
your field of vision until it is completely
closed. Failure to do so can result in
injuries.
Remove the key from the ignition and
close the doors when you leave the ve-
hicle so that children cannot operate
the sunroof and possibly injure them-
selves.<
To avoid pressure or drafts in the pas-
senger compartment when the sunroof
is open or raised, keep the air vents in
the dashboard open and increase the air
supply if necessary. Refer to page 89.
If the sunroof is completely open, air
disturbances may be caused in the
vehicle when you are driving at higher
speeds. Close the roof as far as is nec-
essary until this natural phenomenon
ceases.
For the convenience operating mode
with the door lock or the remote con-
trol, refer to page 34 or 35.
Lifting Ð Opening Ð ClosingIn ignition key position 1 or 2, press the
switch or slide it to the desired direction
until you feel resistance.
When lifting, the headliner retracts
several inches.
After the ignition has been switched off,
you can still operate the sunroof for up
to 15 minutes, as long as neither of the
front doors has been opened.Automatic opening and closing>Press the switch past the resistance
point briefly: The sunroof travels to
either the fully-closed or fully-open
position.460de015

Sliding/Tilt sunroof
*
>With the sunroof open, press the
switch briefly toward "Lift:" The sun-
roof automatically extends to its fully
raised position.
Pressing the switch again briefly stops
the motion immediately.
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
sunroof will open again slightly.
Despite this safety feature, always
be careful to ensure that the clos-
ing path of the roof is not obstructed.
Otherwise, an object might not touch
the contact strip in some situations
(very thin objects, for instance).
You can disable this safety feature by
pressing the switch beyond the resis-
tance point and holding it.<
Power loss or malfunctionIn the event of an electrical system mal-
function, the sliding/tilt sunroof can be
manually operated. Refer to page 156.

For your personal safety when adjusting
the seat position, please follow the in-
structions below carefully:
Never try to adjust your seat while
operating the vehicle. The seat
could respond with an unexpected
movement, and the ensuing loss of ve-
hicle control could lead to an accident.
Be sure that the safety belt remains
firmly against your body at all times. In
the event of a frontal impact, a loose lap
belt could slide over the 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 angle (especially important
for the front passenger to remember).
If you do so, there is a risk that you will
slide under the safety belt in an acci-
dent, thus reducing the protection pro-
vided by the safety belt.<
1 Longitudinal adjustment
Pull the lever and slide the seat to the
desired position.
After releasing the lever, apply pres-
sure to the cushion to ensure that the
latch engages securely.
2 Cushion height

Mechanical seat Head restraints 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.
In the ideal sitting posture, your head is
positioned along a straight line in rela-
tionship to your spinal column.
For long-distance driving, you may wish
to increase the backrest angle slightly
to reduce muscular tension. You should
be able to grasp the steering wheel at
its highest point with your arms slightly
bent.
After a seat adjustment, adjust the
height of the safety belt also. Refer to
page 54.
Adjustments Height: Adjust by pulling up or pushing
down.
In order to move to the lowest
positions, press button 1.<
To adjust the angle of the front head
restraints:
Rotate them in the desired direction.
Head restraints reduce the risk of
injury to the cervical vertebra in
the event of an accident.
Adjust the head restraint so that its
center is approximately at the height of
your ears.<460de283
