Luggage compartment
Tie-down eyelets
The luggage compartment is equ ip p ed with f our tie -down
eyelets to secure luggage and other items.

e ye let s
- Use the tie-dow n eyelets to secure yo ur cargo properly
=> fig . 104 -arrows- .
- Read and heed all WAR NINGS=>
page 207, "Stowing
luggage".
In a collision , the laws of physics mean that even smaller items that
are loose in the vehicle will turn into heavy missiles that can cause
serious injury. Items in the vehicle pick up kinetic energy which
varies with the vehic le and the weight of the item . Vehicle speed is
the most significant factor.
For example , in a frontal collision at a speed of 30 mph (48 km /h) ,
the forces acting on a 10-lb (4 .5 kg) object are abou t
20 times the
normal weight of the item . This means that the weight of the item
would suddenly be the equivalent of about 200 lbs (90 kg). One can
easily imagine the injuries that an i tem of that weight flying free ly

The mounting hooks are spring-loaded and will return to their
normal position when not in use.
& WARNING
For strength-related reasons, the mounting hooks can only be
used to secure objects weighing up to 10 lb .
15 kgl. Heavier objects
will not be adequately secured -there is a risk of injury. •

& WARNING (continued)
• Maintain plenty of distance from an obstacle, so that your
outside mirror or a corner of your vehicle does not collide with any
obstacles -danger of accident!
• The Audi parking system is not a substitute for being careful
and alert when backing up. Be especially careful during parking
and similar maneuvers. Always watch where you are driving and
make sure that nothing is in the way.
• When maneuvering or parking , do not only use the MMI Display
for orientation. Certain objects -depending on the screen resolu­
tion -may not, or not entirely, be displayed; for example trailer
hitches , chains, narrow posts, or fences . •
