Important safety notes
GWARNING
Parts of the body could become trapped dur-
ing automatic closing of the tailgate. In addi-
tion, people may be standing in the closing

dren, during the closing procedure. There is a
risk of injury.
Make sure that nobody is in the vicinity of the
closing area during the closing process.
Release the remote operating switch imme-
diately if somebody becomes trapped. To re-
open the tailgate pull on the remote operating switch.
GWARNING
Combustion engines emit poisonous exhaust
gases such as carbon monoxide. If the tailgate is open when the engine is running, particu-
larly if the vehicle is moving, exhaust fumes
could enter the passenger compartment.
