~ Always read and follow the instructions pro­
vided by the roof rack manufacturer when
installing the roof rack system.
If luggage or cargo is to be carried on the roof, you must observe the following:
- Only use roof racks approved for your vehi ­
cle. These approved roof racks are the basis
for a complete roof rack system. Additional
attachmen ts or carrier systems are needed
to transport luggage a nd sports equ ipment .
We recommend using roof racks from the
Audi original accessories program.
- When installing the roof rack, make sure it
is only mounted on the designated locations
on the roof ¢
fig. 75 or¢ fig. 76 .
- We recommend that you keep the installa­
tion instructions for your roof rack system
together with your Owner 's literature in the
veh icle .
Sea ts a nd s to rage 69
When sh ould th e ro of rac k be r emo 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 cons ump­
tion, wind noise and to guard against theft.
A WARNING
=
- Use of an unapproved roof rack or incor-
rect mounting of an approved roof rack
can cause the roof rack or the items at­
tached 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 desig­
nated locations on the roof
i:> fig . 75.
- The roof rack system must be installed
exactly according to the instruct ions pro­
vided.
- When driving with a roof rack system,
changes to the center of gravity and wind
resistance can change the vehicle han ­
dling and lead to a collision . Always
adapt your driving and your speed to the
cur ren t conditions.
(D Note
- Your vehicle warranty does not cover any
damages to the veh icle caused by using
roof racks or mounting structures not
approved by Aud i for your veh icle. The
same app lies to damage resulting from
incorrect roof rack installation.
- Always check the roof rack mountings
and hardware before each trip and d ur­
ing a trip to make sure everything is se­
curely tightened. If necessary, retighten
the mountings and check the entire sys­
tem from time to time.
- After mounting a roof rack system, or
when you transport objects on the roof
of your vehicle, the height of the veh icle
is naturally increased. Be careful when
dr iving under low bridges or in parking
garages for example . This cou ld cause
111>

70 Seat s a nd s tor ag e
damage to the load and even the vehicle
itse lf.
- Make sure that the open rear lid and the
sunroof do not come into contact with
objects on the roof.
Loading the roof rack
Always distribute loads evenly. J\llake sure
anything on the roof rock is securely tied
down.
.. Always dist ribute the loads on the roof rack
evenly .
.. Always attach items to the roof rack securely
before you drive off.
The maximum permissible roof weight is
2 00 lb (90 kg ). The roof weight is the total of
the we ight of the roof rack, the attachments
and the cargo you are carry ing. You must also
not exceed the maximum load weight for the
roof rack you are using .
When us ing a roof rack system which has a
lower load carry ing capac ity , you must not use
up the total max imum perm issible load carry­
ing capacity specified above. Instead, you
should load the roof rack system only to the maximum capacity spec ified by the manufac­
turer of the roof rack system.
A WARNING
Weak, damaged or improper straps used
to secure items to the roof rack can fail
during hard braking or in a co llision and
cause serious personal injury.
- Make sure the roo f rack is insta lled exact­
ly as specified above
,=;,page 69.
- Always use suitable mounting straps for
sec uring items to the roof rack to help
prevent items from shifting or flying for­
ward.
- Items on the roof rack must always be
sec urely mo unted.
- T he use of a roof rack can negative ly af ­
fect the way a vehicle handles . Cargo
that is large, heavy, bulky, long or flat
will have a greater negative influence on
.
the vehicle's aerodynamics, center of
grav ity and overall handling. Always
drive s lowly, avoid sudden braking and
maneuvers when transporting cargo on
the roof of your vehicle.
- Never exceed the maximum permissible
load carrying capacity of the roof of your
veh icle, the permissible axle weights and
the permissible total weight of you r vehi­
cle~
page 280, Weights.
(D Note
Make sure that the opened rear lid does
not come in contact with the cargo on the
r oof.
@ For the sake of the environment
As a result of the increased wind resist­
ance created by a roof rack, you r vehicle is
us ing fuel unnecessarily . So remove the
r oof rack after using it.

7 4 Seats and storage
If nothing is hung on the hooks, they will fold
back in by themselves.
In a collision, the laws of physics mean that
even smaller items that are loose in the vehi­
cle will turn into heavy missiles that can cause
serious injury. Items in the vehicle p ick up ki­
netic energy which varies with the vehicle 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 (5 kg) object a re about
20 times the
normal weight of the item. This means that
the weight of the item would suddenly be the
equ ivalent of about 200 lbs (90 kg). One can
easily imagine the injuries that an item of that
weight flying freely through the passenger
compartment can cause in a collision at a
speed considered relatively low .
8_ WARNING
Weak, damaged or improper straps used
to secure items to tie-downs can fail dur­ ing hard braking or in a collision and cause
serious personal injury.
- Always use suitable retaining straps and
properly secure items to the tie-downs in
the luggage compartment to help pre­
vent items from shifting or flying for­
ward .
- Never attach a child seat tether strap to
a tie -down.
- For strength-related reasons, the mount­
ing hooks can only be used to secure ob­
jects weighing up to 10 lb. (5 kg) . Heavi ­
er objects will not be adequately secured
- there is a r isk of injury.
Tie-downs
Applies to vehicles: with tie-downs
Four tie-downs for securing luggage pieces
and two for hanging bags , sacks, etc. are
lo­
cated in the luggage compartment.

78 Warm and cold
Warm and cold Climate controls
Description
The climate control system warms, cools and
adds humidity to the air in the vehicle interior.
It is the most effect ive when the windows and
sunroof are closed . If there is a build-up of
heat inside the vehicle, ventilation can help to
speed up the cooling process.
I n all heating mode functions except
defrost,
the blower on ly switches to a higher speed
once the engine coolant has reached a certain
temperature.
Condensat ion from the cooling system can
drip and form a puddle of water under the ve­
hicle. This is normal and does not mean there
is a leak.
Pollutant filter
The pollutant filter removes pollutants s uch
as dust and pollen from the air.
The air pollutants filter must be changed at
the intervals spec ified in you r Warranty
&
Maintenance booklet, so that the air condi­
tioner can properly work.
If you drive your vehicle in an area with h igh
a ir po llution, the fi lter may need to be
changed more frequent ly than specified in
your Aud i Wa rranty
& Ma intenance booklet. If
in doubt, ask your authorized Audi Service Ad ­
visor for advice .
Key coded settings
The climate control settings are automat ically
stored and assigned to the remote control key
that is in use.
A WARNING
Reduced visibility is dangerous and can
cause accidents.
-
- For safe driving it is very important that
all windows be free of ice, snow and con­
densation.
- Comp letely familiarize yourself with the
proper use and function of the heating
and ventilation system and especially how to defog and defrost the windows.
- Never use the windshield wiper/washer
system in freez ing weather unt il you
have warmed the windshield first, using
the heating and ventilation system. The
washer solution may freeze on the wind­ shie ld and reduce visib ility.
(D Note
- If you suspect that the air conditioner
has been damaged, switch the system
off to avoid further damage and have it
inspected by a qualified dealership.
- Repairs to the Audi air conditioner re­
quire special technical know ledge and
special tools. Contact an authorized Aud i
dea ler fo r assistance.
@ For the sake of the environment
By reducing the amount of fuel you use,
you also reduce the amount of pollutants
emitted into the air.
(D Tips
-Keep the air intake s lots (in fro nt of the
w indshield) free from ice, snow and de ­
bris in order to maintain the proper func­
tion of the climate control system.
- T he 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.
- Air escapes through vents under the rear
window. When placing items of clothing
on the luggage compartment cover, en­
sure that the openings are not covered.
