Alarm systemTo arm and disarm the alarm
systemWhen 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
arming and disarming.<
You can also open the luggage com-
partment lid/tailgate when the system is
armed by pressing the button on the
remote control (refer to page 35). When
you close the luggage compartment lid/
tailgate, the luggage compartment 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: door(s), the hood or luggage
compartment lid/tailgate are not
completely closed. Even if you do not
secure the indicated area, the system
begins to monitor the remaining
areas, and the indicator lamp flashes
continuously after 10 seconds. How-
ever, 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 armed390de020
>If the indicator lamp flashes for
10 seconds when the system is
disarmed: an attempted entry has
been detected in the period since the
system was armed.
Following triggering of an alarm, the
indicator lamp will flash continuously.Avoiding unintentional alarmsThe tilt alarm sensor and interior motion
sensor may be switched off at the same
time. To prevent an unintentional alarm
from being triggered (in garages with
elevator ramps, for instance), or when
the vehicle is transported by trailer or
train:
Lock the vehicle (arm the alarm system)
twice in succession: press button 2 on
the remote control twice (refer to
page 35), or turn the key in the door
lock to the right (lock) twice in succes-
sion (refer to page 33).
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.

Park Distance Control (PDC)
*
ASC+T/DSC
*
PDC does not remove the driver's
personal responsibility for evalu-
ating the distance between the vehicle
and any obstacles. Even with the sen-
sors, there is a blind spot in which
objects cannot be detected. This
applies especially in those cases where
the system approaches the physical
limits of ultrasonic measurement, as
occurs with tow bars and trailer cou-
plings, and in the vicinity of thin or
wedge-shaped objects.
Certain sources of sound, such as a
loud radio, could drown out the PDC
signal tone.<
Keep the sensors clean and free
of ice or snow in order to ensure
that they continue to operate effec-
tively.
Do not apply high pressure spray to the
sensors for a prolonged period of time.
Maintain an adequate distance of more
than 4 in (10 cm).<
Automatic Stability Control plus
Traction (ASC+T)/Dynamic
Stability Control (DSC)
*
These systems contribute to additional
vehicle stability, especially during
acceleration and when cornering.
The DSC system enhances the benefits
of the ASC+T. In addition to optimizing
vehicle stability and traction during
acceleration or when starting from a
standstill, a further benefit is realized in
cornering. This, of course, is true only
within physically feasible limits.
The system activates automatically
each time you start the engine.
