Luggage compartment with movement
activated opening
Applies to: vehicles with convenience key and sensor-control·
led luggage compartment lid
Fig. 31 Rear of vehicle: foot movement
Requirements: You must be carrying your vehicle
key with you. You must be standing at the center
behind the luggage compartment lid. The d is
tance to the rear of the vehicle must be at least
8 inches (20 cm) . The ignition must be switched
off. Make sure you have firm footing.
.. Swing your foot forth and back below the
bumper
r=) fig . 31. Do not touch the bumper.
Once the system recognizes the movement, the
luggage compartment lid will open.
The luggage compartment lid will only open if
you make the movement as described. This pre
vents the luggage compartment lid from opening
due to similar movements such as when you walk
between the rear of the vehicle and your garage
door.
General information
In some s ituations, the function is limited or
temporarily unavailable. This may happen if:
- the luggage compartment lid was just closed .
- you park close to a hedge and the branches
move back and forth under the vehicle for a
long period of time .
- you clean your vehicle, for example with a pres
s ure washer or in a car wash .
- there is heavy rain.
- the bumper is very dirty, for example after driv-
ing on salted roads.
- there is interference to the radio signal from
the vehicle key, such as from cell phones or re
mote controls.

.. Remove the mechanical key Q page 31.
.. Insert the key in the lock cylinder as p ictured.
.. Turn the key approximately 45° to the right
r=) fig. 32. The luggage compartment lid opens .
In this position the key cannot be pulled out of
the lock cylinder.
Parental control

doors
The child safety lock prevents the rear doors
from being opened from the inside.

The child safety lock is visible only when the door
is open.

Smart Technology
ignition switched off, it controls the energy sup
p ly to the various electrical components. Data
from battery diagnosis is considered.
Depending on the battery's state of charge, indi
vidual consumers are gradually turned off to pre
vent excessive discharge of the battery and thus maintain starting capability.
Dynamic energy management
While the vehicle is being driven, dynamic energy
management distributes the energy generated
according to the needs of the individual compo
nents.
It regu lates consumption, so that more
electrical energy is not being used than is being
generated and ensures an optimal state of
charge for the battery.
(D Tips
- But even energy management cannot neg
ate the limits of physics . Cons ider that the
power and life of a battery are limited.
- If starting ability is threatened, the indica
tor light (•) appears

What you should know
The highest priority is given to maintaining start
ing capability .
The battery is severely taxed in short-distance
driving, in city traffic and during the cold time of
year. Abundant electrical energy is required, but
only a little is generated . It is also crit ica l if the
engine is not running and electrical components
are turned on . In this instance energy is be ing
consumed but none is being generated .
It is in precisely these situations that you will no
tice energy management actively regulat ing the
d istr ibut ion of energy .
Vehicle stands for an extended period
If you do not driv e your vehicle over a period of
several days or weeks, electrical components are
gradually cut back or switched off. This reduces
energy consumption and ma inta ins starting ca
pability over a longer period . Some of the con
ven ience funct ions may not operate, such as the
interior l ights or the power seat adjustment. The
196
convenience functions will be availab le again
when you switch on the ignition and start the en gine.
With the engine turned off
If you listen to the radio, for example, with the
engine turned off or use other MMI funct ions,
the battery is being d ischarged .
If starting capab ility is jeopardized due to energy
consumption, a message appears in the MMI dis
play .
The message indicates that the system will be
switched off automat ically in a moment . If you
wish to cont inue using the functions, you have to
start the engine.
With the engine running
Although electrica l energy is generated when the
vehicle is being driven, the battery can become
discharged. This happens mostly when little en
ergy is being generated and a great deal con
sumed and the battery's state of charge is not
opt imal.
To bring the energy balance back into equilibr i
um, consumers wh ich require espec ially large
amounts of energy are temporarily cut back or
switched off. Heating systems in particular re
quire a great dea l of energy. If you notice , fo r ex
amp le, that the heated seats* or the heated rear
window are not heating, they have been tempo
rarily cut back or switched off. These systems will
be available aga in as soon as the energy balance
has been restored.
You will also notice that engine idle speed has
been increased slig htly. This is norma l and not a
cause for concern . By increasing engine idle
speed the additional energy required is generat
ed and the battery is charged.
