Luggage compartment

weight. Therefore, the open luggage com-
partment lid must be given additional sup-
port or the cargo must first be removed
from the luggage rack.
— Applies to: vehicles with power-operated or
sensor-controlled luggage compartment lid:
Pay careful attention when closing the lug-
gage compartment lid. Otherwise, you could
cause serious injury to yourself or others de-
spite the pinch protection.
ZA\ WARNING
— Applies to: vehicles with anti-theft alarm
system: No one, especially children, should
stay in the vehicle when it is locked from the
outside, because the windows can no longer
be opened from the inside > page 46.
Locked doors make it more difficult for
emergency workers to enter the vehicle,
which puts lives at risk.
— Always close and lock the luggage compart-
ment lid and the doors when the vehicle is
not in use. Otherwise someone such as a
child could enter the vehicle through the
luggage compartment and become locked
inside it. To reduce the risk of injury, do not
allow children to play in or around the vehi-
cle.
—To reduce the risk of injuries by pinching,
make sure that no one is in the operating
area of the luggage compartment lid, in-
cluding the hinge areas and the upper and
lower edge of the luggage compartment lid.
—
After closing the luggage compartment lid,
make sure that it is latched. The luggage
compartment lid could open suddenly while
driving, which would increase the risk of an
accident.
— Never drive with the luggage compartment
lid ajar or open, because poisonous gases
from the surrounding area can enter the ve-
hicle interior and increase the risk of asphyx-
iation.
— If there is a luggage rack (such as a bicycle
rack) on the luggage compartment lid, the
luggage compartment lid may not open
completely under certain circumstances or it
could close by itself if open due to the extra
sO
G) Tips
— When the vehicle is locked, the luggage
compartment lid can be unlocked separately
by pressing the
on the vehicle key. The luggage compart-
ment lid locks automatically when it is
closed again.
— The ability to open the luggage compart-
ment lid using the handle can be deactivat-
ed or activated in the MMI > page 44.
— The luggage compartment can be opened
from the inside in an emergency
=> page 53.
