A WARNING
- Never close the rear lid inattentively or with­
out checking first . Although the closing
Op ening and cl osing
force of the rear lid is limited, you can still
seriously injure yourself or others.
- Always ensure that no one is within range of
the rear lid when it is moving, in particu lar
close to the hinges and the upper and lower
edges - fingers or hands can be pinched.
- To help prevent poisonous exhaust gas from
be ing drawn into the vehicle, a lways keep
the rear lid closed while dr iving. Never
transport objects larger than those which fit
comp letely into the luggage area, because
then the rear lid cannot be fully closed.
- Never leave your veh icle unattended espe­
cially with the rear lid left open. A child
could crawl into the car through the luggage
compartment and pull the lid shut, becom­
ing trapped and unab le to get out. To re­
duce the risk of personal in jury, never let
children play in or around your vehicle . Al­
ways keep the rear lid as we ll as the veh icle
doors closed when not in use .
- If there is a luggage rack or bicycle rack
mounted on the rear lid, it may not be able
to open comp letely or an opened rear lid
may close by itself because of the added
weight . So the open rear lid must be sup­
ported or the we ight must be removed from
the l uggage rac k first.
(!) Tips
- When the vehicle is locked, the rear lid can
be unlocked separately by pressing the but­
ton~ on the master key . When the rear lid
is closed again, it locks automatically.
- The following applies to vehicles equ ipped
w ith the convenience key* feature : if the re­
mote contro l key is left in the luggage com­
partment , luggage compartment will auto­
matically unlock itse lf after you lock the ve ­
hicle. This prevents you from unintentiona l­
ly locking your key in the luggage compart­
ment.
- If the vehicle battery charge drops below a
certain level, you can still open or close the
rear lid manually, however, you will need to
app ly more force to close it.
