General hints for operating
tailgate9 Danger
Do not drive with the tailgate open
or ajar, e.g. when transporting
bulky objects, since toxic exhaust
gases, which cannot be seen or
smelled, could enter the vehicle.
This can cause unconsciousness
and even death.
Caution
Before opening the tailgate, check overhead obstructions, e.g. a
garage door, to avoid damage to
the tailgate. Always check the
moving area above and behind the
tailgate.
Notice
The installation of certain heavy
accessories onto the tailgate may
affect its ability to remain open.
Notice
The operation of the power tailgate
is disabled under low vehicle battery
conditions. In this case, the tailgate
may not even be manually operable.
Notice
With the power tailgate disabled and
all doors unlocked, the tailgate can
only be operated manually. In this
event, manually closing the tailgate
requires significantly greater force.
Notice
At low outside temperatures the
tailgate may not open fully by itself.
In this event, lift the tailgate manually
to its normal end position.
