Roof rack
Description and mounting locations
Additional cargo can be carried with a roof luggage rack .
Fig. 64 Roof rack attachment poin ts
.,. 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:
- Your vehicle has aerodynamic rain gutters
molded into the roof. This is why conven­
tional roof luggage racks cannot be used.
We recommend using roof racks from the
Audi original accessories program.
- Only use roof racks approved for your vehi­
cle. These approved roof racks are the basis
for a complete roof rack system. Additional
attachments or carrier systems are needed
to transport luggage and sports equipment.
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. 64.
-We recommend that you keep the installa­
tion instructions for your roof rack system
together with your Owner's literature in the
vehicle .
When shoul d th e r oof ra ck be re moved?
- 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 consump­
tion, wind noise and to guard against theft .
Sea ts a nd s to rage 63
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¢
fig. 64.
- The roof rack system must be installed
exactly according to the instructions 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 col lision. Always
adapt your driving and your speed to the
current conditions .
(D Note
-Your vehicle warranty does not cover any
damages to the vehi cle caused by us ing
roof racks or mounting structures not
approved by Audi for your vehicle. The
same applies to damage resulting from
incorrect roof rack installation.
- Always check the roof rack mountings
and hardware before each trip and dur­
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
damage to the load and even the vehicle
itself .
- Make sure that t he open rear lid and the
sunroof do not come into contact with
objects on the roof.

64 Seats and storage
loading the roof rack
Always distribute loads evenly . Make sure
anything on the roof rack is securely tied
down.
,. Always distribute the loads on the roof rack
evenly .
,. Always attach items to the roof rack secure-
ly befo re you dr ive off.
The maximum perm iss ible roof we ight 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 car ry ing. You m ust also
not exceed the maximum load weight for the
roof rack you are using.
When us ing a roof rack system which has a
l owe r load carry ing capac ity, you must not use
up the total max imum pe rm issib le load carry ­
i ng capac ity specified
above . Instead, you
should load the roof rack system only to the
maximum capacity specified 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 collision and
cause se rious personal injury .
- Make sure the roof rack is insta lled exact­
ly as specified
above ¢ page 63.
- Always use suitable mounting straps for
sec uring items to the roof rack to help
prevent items from shift ing o r fly ing for­
wa rd.
- Items on the roof rack must always be sec urely mounted.
- The use of a roof rack can negative ly af­
fect the way a vehicle handles . Ca rgo
that is larg e, h eavy, bulky, long o r flat
will have a g reater negative influence on
the vehicle's aerodynamics, center of
gravity and overal l ha ndling. Always
dr ive slowly, avo id sudden braking and
mane uvers when transporting cargo o n
the roof of your vehicle.
- Never exceed the maxim um permissible
load carrying capacity of the roof of your
veh icle, the permissible axle weights and
the permissible total weight of your vehi­ cle ¢
page 268, 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, your vehicle is
us ing fuel unnecessarily. So
remove the
r oof rack after using it .

kinetic energy which varies with the vehicle
and the weight of the item . Vehicle speed is
the most significant factor .
F or example, in a frontal coll is ion at a speed
of 30 mph ( 48 km/h), the forces acting on a
10 -lb (5 kg) object are about 20 times the
normal weight of the item. Th is means that
the weight of the item would suddenly be the
equivalent of about 200 lbs (90 kg). One can
eas ily imagine the injur ies that an item of that
weight flying freely through the passenger compartment can cause in a co llision at a
speed conside red relat ively low.
& WARNING
Weak, d amaged or improper s traps used
to secure items to t ie-downs can fail du r­
ing hard brak ing or in a coll ision and cause
serious persona l in jury .
- Always use suitab le 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). Heav i­
er objects w ill not be adequately secured

Seat s an d sto rage 67

68 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.
