Rolling code programming
Applies to vehicles: with garage door opener ( Homelink)
Rolling code programming is also needed for
some systems.
Identifying a rolling code
.. Press and hold the button in the roof head­
liner that was already programmed .
.. Watch the LEO@q
page 46, fig. 41. If the
LED blinks quickly, the systems (such as a
garage door) is equipped with a rolling code .
.. Program the rolling code as follows:
Activating the motor unit in a system
.,. Locate the programming button on the sys­
tem's motor unit. The exact location and
color of the button may vary depending on
the brand of the system .
.,. Press the programm ing button on the ga­
rage door opener motor unit (th is w ill usual­
l y activate an "indicator" on the motor unit).
You now have approximately
30 seconds to
program the button in the roof headliner.
Programming the button in the roof
headliner
.,. Press and hold the previously programmed
button in the roof headliner for 2 seconds .
.. To end rolling code programming, press and
ho ld the button again for 2 seconds .
.,. With some systems, the button may need to
be pressed a third time to end the program­
ming process.
After programming, the system should detect
the signal and beg in mov ing when the button
in the roof headliner is pressed. Now you may
program the other buttons as needed.
{D) Tips
-The roll ing code can be programmed
more quickly and more easily with the
help of a second person.
- If you have difficulty programming the
rolling code, referring to the user gu ide
for the system may help.

68 Seats and stor age
Addit ional storage
There are a variety of storage compartments
and fasteners in var ious places in the vehicle.
- In the roof headliner above the rearview
mirror .
- On the back of the front seat . The com pa rt­
ment can hold a maximum weight of 1 kg.
- On the left and right of the luggage com­
partment, behind the side trim.
- Garment hooks on the pillars in the rear of
the vehicle .
A WARNING
-When driving, do not leave any hard ob­
jects on the rear window shelf or allow your pet to s it on the shelf. They could
become a hazard for ve hicle occupants in
the event of sudden braking or a crash.
- Always remove objects from the instru­
ment pane l. Any items not stored could
slide around inside the vehicle while driv­
ing or when accelerating or when apply­
ing the brakes or when driving around a
corner.
- When you are driving make sure that
anything you may have placed in the cen­
ter console or other storage locations cannot fall out into the footwells. In case
of sudden braking you would not be able
to brake or accelerate.
- Any articles of clothing that you have
hung up must not interfere with the driv­
er's v iew. The coat hooks are designed
only for lightweight clothing. Never hang
any clothing with hard, pointed or heavy
objects in the pockets on the coat hooks.
During sudden braking or in an accident -
especially if the airbag is deployed -
these objects could injure any passen­
gers inside the vehicle .
- To reduce the risk of personal injury in an
accident or sudden stop, always keep the
glove compartment closed while driving.
- Read and follow all WARNINGS
i=> page 161, Important safety instruc­
tions on the side airbag system.
- Hang clothes in such a way that they do
not impair the driver's vision.
- The coat hooks must only be used for
lightweight clothing. Do not leave any
heavy or sharp edged objects in the pock­
ets which may interfere with the side cur­
tain airbag deployment and can cause personal injury in a crash.
- Do not use coat hangers for hanging
cloth ing on the coat hooks as th is can in­
terfere with proper deployment of the
side curtain air bags in an accident.
- Do not hang heavy objects on the coat
hooks, as they could cause personal in­
jury in a sudden stop.
- Always keep the compartment above the
rea rv iew mirror closed while driving to
red uce the risk of injury in the event of
sudden braking maneuvers or a collision.

Fig. 76 allroa d: Roof ra ck atta chm ent po ints
~ 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.

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.

132 Driving Safel y
-Always make sure that objects cannot
fall into the driver footwe ll wh ile the ve­
hicle is moving. Objects can become
trapped under the brake pedal and accel­
erator peda l causing a loss of veh icle
contro l.
Stowing luggage
Loading the luggage compartment
All luggage and other objects must be prop­
erly stowed and secur ed in the luggage com­
partment.
Fig. 141 S afe load positio nin g: place heavy objects as
l ow a nd a s far forward as pos sible.
Loose items in the luggage compartment can
shift suddenly, changing vehicle hand ling
characteristics. Loose items can also increase
the risk of serious personal injury in a sudden
vehicle maneuver or in a collision .
.,. Distribute the load even ly in the luggage
compartment .
.,. Always place and properly secure heavy
items in the luggage compartment as low
and as far forward as possible¢
fig. 141.
.,. Secure the load with the cargo net* or with
non -elastic straps secured to the tie-downs*
¢ page 73 ¢page 74.
.,. Make sure that the rea r seatback is secu rely
latched in place.
.&_ WARNING
Improperly stored luggage or other items
can fly throug h the vehicle ca using serious
personal inj ury in the event of hard brak­
ing or an accident. To help reduce the r isk
of serious personal injury: -
Always put objects, for example, luggage
or other heavy items in the luggage com ­
partment.
- Always secure objects in the luggage
compartment using the t ie-down eyelets
and suitable straps.
.&_ WARNING
-
Heavy loads w ill influence the way your ve­
hicle handles . To help reduce the risk of a
l oss of cont rol leading to serious personal
in jury:
- Always keep in mind when transporting
heavy objects, that a change in the cen­
ter of gravity can also cause changes in
veh icle handling :
- Always distribute the load as evenly as
possible.
- Place heavy objects as far forward in
the luggage compartment as possible .
- Never exceed the Gross Axle Weight Rat­
ing or the Gross Vehicle Weight Rating
specified on the safety compliance stick­
er on the left door jamb. Exceeding per­
miss ible weight standards can cause the
veh icle to slide and hand le differently.
- Please observe information on safe dr iv­
ing
c:> page 126.
.&_ WARNING
To help prevent poisonous exhaust gas
from being drawn into the vehicle, always
keep the rear lid closed while driving.
- Never transport objects larger than
those fitting completely into the luggage
a rea because the rear lid cannot be fully
closed.
- If you absolutely m ust dr ive with the rear
lid open, observe the following notes to
red uce the risk of poisoning:
- Close all windows,
- Close the sunroof,
- Open all air outlets in the instrument

A WARNING
Always make sure that the doors, all win­dows, the sunroof and the rear lid are se ­
curely closed and locked to reduce the risk
of injury when the vehicle is not being
used.
- After closing the rear lid, always make
sure that it is properly closed and locked.
- Never leave your vehicle unattended es­
pecially with the rear lid left open . A
child could crawl into the vehicle through
the luggage compartment and close the
rear lid becoming trapped and unable to
get out. Being trapped in a vehicle can
lead to serious personal injury.
- Never let children play in or around the
vehicle .
- Never let passengers ride in the luggage
compartment. Vehicle occupants must
always be properly restrained in one of
the vehicle's seating positions.
(D Tips
- Air circulation helps to reduce window
fogging. Stale air escapes to the outside
through vents in the trim panel. Be sure
to keep these slots free and open .
- The tire pressure must correspond to the
load. The tire pressure is shown on the
tire pressure label. The tire pressure la­
bel is located on the driver's side B-pillar.
The tire pressure label lists the recom­
mended cold tire inflation pressures for
the vehicle at its maximum capacity
weight and the tires that were on your
vehicle at the time it was manufactured.
For recommended tire pressures for nor­
mal load conditions, please see chapter
c:>poge234.
Driving Safely 133
Tie-downs
App lies to veh icles : w ith tie -d owns
The luggage compartment is equipped with
four tie-downs to secure luggage and other
items .
Use the tie-downs to secure your cargo prop­
erly
c:> page 132 , Loading the luggage com ­
partment .
In a collision, the laws of physics mean that
even smaller i tems that are loose in the vehi­
cle will become heavy missiles that can cause
serious injury. Items in the vehicle possess en­
ergy which vary with vehicle speed 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 about 20 times the
normal weight of the item . This means that
the weight of the item would suddenly be
about 200 lbs. (90 kg). You can imagine the
injuries that a 200 lbs. (90 kg) item flying
freely through the passenger compartment could cause in a collision like this.
A 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 mounting straps and
properly secure items to the tie-downs in
the luggage compartment to help pre­
vent items from shifting or flying for­
ward as dangerous missiles.
- When the rear seat backrest is folded
down, always use suitable mounting
straps and properly secure items to the
tie-downs in the luggage compartment
to help prevent items from flying for­
ward as dangerous missiles into the pas­
senger compartment .
- Never attach a child safety seat tether
strap to a tie-down . •
