gases such as carbon monoxide. Exhaust
gases can enter the vehicle interior if the
trunk lid is open when the engine is running,
especially if the vehicle is in motion. There is a
risk of poisoning.
Always switch off the engine before opening
the trunk lid. Never drive with the trunk lid
open.
!The trunk lid swings upwards when opened.
Therefore, make sure that there is sufficient
clearance above the trunk lid. The opening dimensions of the trunk lid can be
found in the "Vehicle data" section
(
Ypage 336).
You should preferably place luggage or loads in
the trunk. Observe the loading guidelines
(
Ypage 251).

is only an aid and is not a substitute for your
attentiveness to the trunk lid while it is closing.
GWARNING
The reversing feature does not react:
Rto soft, light and thin objects, e.g. small fin-
gers
Rover the last 1/3 in (8 mm) of the closing

This means that the reversing feature cannot
prevent someone being trapped in these sit-
uations. There is a risk of injury.
