Always leave the lid on the glove compart­ment cover closed while driving to reduce the
risk of injury.
Additional storage compartments
There are additional storage compartments,
compartments and holders at other locations in

can slide around in the vehicle while driving,
when accelerating or braking or when turn­
ing.
- Make sure that objects cannot fall out of the
center console storage compartment or oth­
er compartments and into the footwell
while driving. These objects could prevent
you from braking or accelerating during sud­
den braking maneuvers.
- Garments hung on the hooks must not ob­
struct the driver's view. The garment hooks
are only designed for light objects . Do not
hang any garments with hard, sharp or
heavy objects in the pockets on the garment
hooks . These objects could injure vehicle oc ­
cupants during sudden brak ing or in a colli­
sion - especially if the airbags deploy.
- Always keep the glove compartment closed
while driving to reduce the risk of injury dur­
ing a collision or heavy brak ing.
- Read and following the WARNINGS in
¢ page 168, Important safety instructions
on the side airbag system.
-Hang garments so that they do not obstruct
the driver's view.
Seats and storage
-The garment hooks should only be used for
light articles of clothing . Do not leave any
heavy or sharp-edged objects in the pockets
that could interfere with the side airbags unfolding and cause injuries in the event of
a collision .
- Do not use coat hangers to hang garments,
because this could reduce the effectiveness
of the side curtain airbags.
- Do not hang any heavy objects on the gar­
ment hooks, because they could cause injury
during heavy braking.
- Because of their load capacity, the hooks
should only be used to secure objects that
weigh a max imum of 10 lb (5 kg). Heavy ob­
jects will not be secured sufficiently, and
this increases the risk of injury.

.,. Always read and follow the instructions provid­
ed by the roof rack manufacturer when instal­
ling the roof rack sys tem.
If luggage or cargo is to be carried on the roof,
you must observe the follow ing:
62
- On ly use roof racks approved for your vehicle.
These approved roof racks are the basis for a
complete roof rack system. Additional attach­
ments or carrier systems are needed to trans­
port luggage and sports equipment. We recom­
mend us ing roof racks from the Audi original
accessories program.
- When installing the roof rack, make sure it is
only mounted on the designated locat ions on
the roof¢
fig. 62.
- We recommend that you keep the installation
instructions for yo ur roof rack system together
w ith your Owner's literature in the vehicle .
When should the roof rack be remo ved?
- Before going through an automatic car wash (it
is best to ask the car wash operator for advice).
- When not in use, to reduce fuel consumption,
w ind no ise and to guard against theft .
A WARNING
-Use of an unapproved roof rack o r incorrect
mounting of an approved roof rack can
cause the roof rack or the items attached to
it to fall off the roof onto the road.
- Objects falling from the roof of a vehicle can
cause a crash and personal injury.
- Only mount the roof rack on the designated
locat ions on the roof¢
fig . 62.
- The roof rack system must be installed ex­
actly according to the instructions p rov ided.
- When driving with a roof rack system,
changes to the center of gravi ty and wind re­
sistance ca n change the veh icle hand ling
and lead to a co llision. Always adapt you r
driving and your speed to the current condi­
t ions.
(D Note
- Yo ur vehicle war ranty does not cov er any
damages to t he vehi cle caused by using roof
racks or mounting structures not ap proved
by Audi for yo ur vehicle. The same a pplies to
damage resulting from incorrec t roof rack
installation .
