& WARNING Risk of injury due to objects
being stowed incorrectly
If objects in the vehicle interior are stowed
incorrectly, they can slide or be thrown around
and hit vehicle occupants. In addition, cup
holders, open stowage spaces and mobile
phone receptacles cannot always retain all
objects within.
There is a risk of injury, particularly in the
event of sudden braking or a sudden change
in direction.
Always stow objects so that they cannot
#
be thrown around in such situations.
Always make sure that objects do not
#
protrude from stowage spaces, parcel
nets or stowage nets.
Close the lockable stowage spaces
#
before starting a journey.
Always stow and secure heavy, hard,
#
pointed, sharp-edged, fragile or bulky
objects in the trunk/cargo compart-
ment.
