_& WARNING
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
the vehicle :
- In the upper part of the glove compartment.
- In the center console under the center arm-
rest* .
- On the back of the right front seat . The com­
partment* can hold a maximum weight of
2 lbs
(1 kg).
- Garment hooks on the B-pillar ¢
&.
_& WARNING
-Do not place any objects on the instrument
panel. Objects that are not stored securely
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.

Roof rack
Description and mounting locations
Additional cargo con be carried with a roof lug­
gage rock.
Fig. 62 Roof rack attachment points
.,. 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 .
- Always che ck the roof rack mountings and
hardware before each trip and du ring a t rip
to make sure everything is secure ly

tightened. If necessary, retighten the mountings and check the entire system
from t ime to t ime.
- After mounting a roof rack system, or when
you transport objects on the roof of your ve­
hicle, the height of the veh icle is naturally
increased. Be careful when driving under
l ow bridges or in parking garages for exam­
ple. This could cause damage to the load
and even the vehicle itself.
- Make sure the open rear lid and the sun­
roof* do not come into contact with the roof
rac k.
Loading the roof rack
Always distribute loads evenly . Make sure any­
thing on the roof rack is securely tied down .
... Always distribute the loads on the roof rack
evenly .
... Always attach items to the roof rack securely
before you d rive off .
The maximum perm iss ible roof weight is
165 lb
( 75 kg ). The roof weight is the total of the
weight of the roof rack, the attachments and the
cargo you a re ca rrying . You must also not exceed
the maximum load weight fo r the roof rack you
a re using.
When using a roof rack system wh ich has a lower
l oad carrying capacity, you must not use up the
tota l maxim um permissible load car ry ing capac i­
ty specified above. Inste ad , you shou ld load t he
roof rack system only to the maximum capacity
specified by the manufact urer of the roof rack
system .
A WARNING
Weak, damaged or improper straps used to
secure items to the roof rack can fa il during
hard brak ing or in a collision and cause seri­
ous personal injury.
- Make sure the roof rack is insta lled exactly
as spec ified above
¢ page 62.
- Always use suitable mounting straps for se­
curing items to the roof rack to help prevent
items from shift ing or f ly ing fo rward.
-
S eat s and stor age
- Items on the roof rac k must always be se­
curely mounted.
- The use of a roof rack can negatively affect
the way a vehicle handles. Cargo that is
large, heavy, bulky, long or flat will have a
greater negative inf luence on the vehicle's
ae rodynamics, center of gravity and overall
h a ndling. Always drive slowly, avoid sudden
b rak ing and maneuvers when transpor ting
cargo on the roof of your veh icle.
- Never exceed the maxim um permissible
load carrying capacity of the roof of your ve­
h icle, the permiss ible axle weights and the
perm issib le tota l we igh t of your vehicle
¢ page 258, Weights .
@ For the sake of the environment
As a result of the increased wind resistance
created by a roof ra ck , your vehicle is using
fuel unnecessarily. So remove the roof rac k af­
ter using it.

Warm and cold
Warm and cold Climate control system
Description
Different systems could be installed.
- manual climate control system* or
- automatic climate control system*
The
climate control system* cools and removes
humidity from the air in the vehic le interior. It is
the most effective when the windows and panor­
ama sunroof* are closed.
If there is a build-up of
heat inside the vehicle, ventilation can help to
speed up the cooling process . For this reason, the
windows and panorama sunroof can be opened
from the outside .~
page 41, Convenience open­
ing/closing
Pollutant filter
The pollutan t filter removes pollutants such as
dust and pollen from the air.
Key recognition
You can store various settings for the manua l and
automatic
climate control system* and assign
them to the key being used .
A WARNING
Poor visibility can lead to acc idents.
- For safer driving, keep all w indows free of
ice, snow and fog.
- Become familiar as quickly as possible with
the correct use and function of the climate
control system, espec ially with the defrost­
ing and defogging function .
- When the temperature is below freezing,
only use the windsh ield washer system after
the windsh ield has been warmed by the cli -
64
mate control system. The washer f luid could
freeze on the w indshield and impair visibili­
ty.
(D Note
- If you suspect that the climate control sys­
tem is damaged, switch the system off to
prevent further damage and have it checked
by an authorized Audi dealer or authorized
Audi Service Facility .
- Repairs to the Audi climate control system
require special technical knowledge and
special tools. See an author ized Audi dealer
or authorized Audi Service Facility .
@ For the sake of the environment
Reducing the amount of fuel used also re­
duces the amount of pollutants that enter the
a ir .
@ Tips
- To prevent interference with the heating
and cooling output and to prevent the win­
dows from fogg ing over, the air intake in
front of the w indshield must be free of ice,
snow or leaves.
- Condensation from the cooling system* can
dr ip and form a pudd le of water under the
vehicle . This is normal and does not mean
there is a leak .
- Th e energy management system may switch
the seat heating* or rear window defroster
off temporarily. These systems are available
again as soon as the energy balance has
been restored.
- The f lows through the vents under the rear
window. Make sure the openings are not
covered when p lacing clothing on the lug­
gage compartment cover.
