The doors are designed to unlock
automatically after an accident if the force of
the impact exceeds a preset threshold.
The vehicle locks automatically when the
ignition is switched on and the wheels are
turning at a vehicle speed of above 9 mph
(15 km/h). You could therefore lock yourself
out when the vehicle is pushed or towed or is
on a test stand.

GWarning!
Make sure the trunk is closed when the engine
is running and while driving. Among other
dangers, deadly carbon monoxide (CO) gases
may enter vehicle interior resulting in
unconsciousness and death.
! When you open the trunk, the trunk lid
swings open upwards. Always make sure
there is sufficient overhead clearance.
You can open the trunk when the vehicle is
stationary and the retractable hardtop is fully
opened or closed.
A minimum height clearance of 6.2 ft (1.88 m)
is required to open the trunk lid.
iTo facilitate trunk loading and unloading
when the hardtop is retracted, you can
raise the hardtop from its storage position
in the trunk using the load assist feature

Power closing assist for trunk lid
It is not necessary to slam the trunk lid
closed. An electrical power-assisted
mechanism draws the trunk lid closed quietly
and automatically once the trunk lid has been
latched. When the electrical power-assisted
mechanism has stopped, the trunk can be
reopened.

keep hands and fingers away from the trunk
opening when closing the trunk lid. Be
especially careful when small children are
around.
In case of danger, pull the inside or outside
door handle, or press the trunk lid lock.
To prevent personal injury, never actuate the
closing assist mechanism by tampering with
the door or trunk lid latch.
