General notes MAGIC BODY CONTROL consists of Active
Body Control (ABC), ROAD SURFACE SCAN,
the CURVE cornering function as well as auto-
matic vehicle stabilization in the event of a
crosswind.
Your vehicle automatically adjusts its ride
height to reduce fuel consumption. The sus-
pension mode is adjusted according to your
selection (SPORT, COMFORT or CURVE), the
road surface conditions and the vehicle load.
A multifunction camera detects bumps in the
road surface before the vehicle drives over
them. This reduces chassis movements.

Detected parking space on the left
0044 Parking symbol
0087 Detected parking space on the right
Active Parking Assist is switched on automat-
ically when driving forwards. The system is
operational at speeds of up to approximately 22 mph (35 km/h). While in operation, the
system independently locates and measures
parking spaces on both sides of the vehicle.
Active Parking Assist will only detect parking spaces:
R parallel or at right angles to the direction of
travel
R that are parallel to the direction of travel
and at least 59 in (1.5 m) wide
R that are parallel to the direction of travel
and at least 39.5 in (1.0 m) longer than your
vehicle
R that are at right angles to the direction of
travel and at least 39.5 in (1.0 m) wider
than your vehicle
i Note that Active Parking Assist cannot
measure the size of a parking space if it is at
right angles to the direction of travel. You
will need to judge whether your vehicle will
fit in the parking space.
When driving at speeds below 19 mph
(30 km/h), you will see the parking symbol as a status indicator in the instrument cluster.
When a parking space has been detected, anarrow towards the right or the left also
appears. By default, Active Parking Assist
only displays parking spaces on the front-
passenger side. Parking spaces on the driv- er's side are displayed as soon as the turn
signal on the driver's side is activated. When
parking on the driver's side, this must remain switched on until you acknowledge the use of
Active Parking Assist by pressing the 0076
button on the multifunction steering wheel.
The system automatically determines
whether the parking space is parallel or at
right angles to the direction of travel.
A parking space is displayed while you are
driving past it, and until you are approx-
imately 50 ft (15 m) away from it.
