– 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.



If the

indicator light appears with a corre-

sponding message, the vehicle key battery is

drained and must be replaced.

WARNING

– To reduce the risk of injuries by pinching,

make sure that no one is in the operating

area of the luggage compartment lid when

closing, especially near the hinges, at the

upper and lower edges of the lid, or all

around the edge of the lid in general.

– After closing the luggage compartment lid,

make sure that it is latched. Otherwise, the

luggage compartment lid could open sud-

denly while driving, which would increase

the risk of an accident.

If batteries or coin cell batteries are swal-

lowed or enter the body in any other way, they

can cause serious injuries or death within a

short period of time. There is a risk of chemi-

cal burns.

– Keep vehicle keys and key fobs with batter-

ies out of the reach of children.

– Keep new or used batteries away from chil-

dren.

– If the battery compartment on a vehicle key

does not close securely, stop using the key

and keep it away from children.

– Never drive with the luggage compartment

lid ajar or open, because exhaust fumes

from outside can enter the vehicle interior

and increase the risk of asphyxiation.

– If there is a luggage carrier (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

weight. Therefore, the open luggage com-

partment lid must be given additional sup-

port or the cargo must first be removed

from the luggage carrier.

– Seek medical attention immediately if you

suspect that a battery was swallowed or has

entered the body in any other way.

For the sake of the environment

Luggage compartment

lid

– Applies to: vehicles with power-operated or

sensor-controlled luggage compartment

General information

lid: Pay careful attention when closing the

luggage compartment lid. Otherwise, you

could cause serious injury to yourself or oth-

ers despite the pinch protection.

WARNING

– No one, especially children, should stay in

the vehicle when it is locked from the out-

side, because the windows can no longer be

opened from the inside. Locked doors make

it more difficult for emergency workers to

enter the vehicle, which increases the risk of

death.

Note

The luggage compartment lid can bump into

objects such as the garage ceiling when open-

ing and become damaged.
