"Read and heed all WAR NINGS 9 page 141,
Stowing luggage .
In a collis ion, the laws of phys ics mean that
even smaller items that are loose in the vehi­
cle will turn into heavy missiles that can ca use
serious in jury . Items in the vehicle pick up ki­
netic energy which varies w ith the vehicle and
the weight of the item . Vehicle speed is the
most signif icant 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 (4 .5 kg) object are about
20 times the
normal weight of the item . This means that
the we ight of the item would suddenly be the equivalent 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 collis ion at a
speed considered relatively low .
A WARNING
-Weak, damaged or imprope r straps used
to secure items to tie-downs can fail dur­ in g hard braking or in a collision and cause
se rio us personal injury.
- Always use su itable reta ining straps a nd
p roperly secu re items to the tie-downs in
the l uggage compa rtment to he lp pre­
vent i tems from shift ing or fly ing fo r­
ward.
- Never at tach a chi ld seat tether strap to
a t ie -down.
- For s trength-re lated reasons, the mou nt­
ing hooks can only be used to secure ob­
jects weighing up to 10 lb. (5 kg) . Heavi ­
er objects will not be adequately sec ured
- there is a risk of injury.

Roof rack
Description and mounting locations
Additional cargo can be carried wi th a roof
luggage rack .
Fig . 74 Roo f ra ck attac hment po ints
.. Always read and follow the instr uct ions pro­
vided by the roof rack ma nufacturer when
i nstall ing the roof rack system .
If luggage or cargo is to be ca rried on the
roof, yo u mus t observe the follow ing:
- To enhance the vehicle 's streamlined design,
ra in gutters have been mo lded i nto t he roof .
I t is not poss ible to use normal roof ra cks.
O nl y install a roof ra ck specific ally designed
for your model AB . Contac t the nea re st Audi
dea ler for information on approved modular
roof racks for your v ehicle.
- On ly use roof racks approved for your vehi­
cl e. These approved roof racks are the basis
fo r a complete roof rack system. Addition al
a tta chmen ts or carr ier systems are needed
t o transpor t luggage and spor ts equipment.
We recommend using roof rack s from the
Aud i original accessories prog ram.
- When insta lling the roof rack, make sure it
is o nly mounted on the designated locations
on the roof~
fig. 74 .
-We recommend that you keep the i nstalla ­
tion instruct ions for your roof rack system
together w ith your Owner's literature in the
ve hicle.
When should the roof rack be removed?
- Before go ing through an au tomatic car wash
(it is best to ask the ca r wash operator for
adv ice)
...

-When not in use, to reduce fuel consump­
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 veh icle
can cause a crash and personal injury .
- Only mount the roof rack on the desig­
nated locations on the roof
c::> fig . 74 .
-The roof rack system must be installed
exactly according to the instructions pro­
vided.
- When driving w ith a roof rack system,
changes to the center of gravity and wind
resistance can change the veh icle han­
dling and lead to a collision . Always
adapt your driv ing and your speed to the
current conditions.
0 Not e
-Your vehicle warranty does not cover any
damages to the vehicle caused by using
r oof racks or mount ing 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
cure ly tightened . If necessary, retighten
the mount ings and check the ent ire sys­
tem from t ime to t ime.
- After mounting a roof rack system, or
when you transport objects on the roof
of your veh icle, the height of the vehicle
i s naturally increased. Be careful when
driv ing under low br idges or in parking
garages for example. This could cause
damage to the load and even the vehicle
i tself.
- Make sure the open rear lid and the sun­
roof* do not come into contac t with the
roof rack .
Seat s an d sto rage 73
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
even ly .
.. Always attach items to the roof rack securely
before you dr ive off.
The maximum permissible roof weight is
2 20
lb (100 kg ).
The roof weight is the total of
the weight of the roof rack, the attachments
and the cargo you a re carrying. You must also
not exceed the maximum load we ight for the
roof rack you are using .
When using a roof rack system which has a l ower load ca rrying capaci ty , you must not use
up the tota l maxim um permissible load car ry ­
i ng capacity specified above . Instead, you
sho uld 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 collis ion and
cause ser ious personal injury.
- Make sure the roof rack is installed exact­
ly as specified above
c::> page 72.
- Always use su itable mount ing straps for
securing items to the roof rack to help
p revent items from sh ifting or flying for­
ward.
- Items on the roof rack must always be
securely mounted.
- The use of a roof rack can negat ively af­
fect the way a veh icle hand les. Cargo
that is large, heavy, bulky, long or flat
will have a greater negat ive influence on
the vehicle's aerodynamics, center of gravity and overall handling . Always
drive s lowly, avoid sudden braking and
maneuvers when transporting cargo on
the roof of your vehicle .

- the temperature in the luggage compart­
ment is below 131 °f (55 °C). The cooler
switches off automatically if the tempera­
ture in the luggage compartment exceeds 131 °f (55 °C) . Once the temperature falls
below 131 °f (55 °C) again, the cooler
switches on aga in automat ically .
- t he battery is adequately charged . The cool­
er switches off automatically if the vehicle
battery voltage falls below a minimum lev­
el. This prevents the batte ry from discha rg­
i ng . The cooler switches back on again auto­
matically when the battery voltage increases
again (e.g . after starting the engine).
The cooler cools to 42.8 °f
(+ 6 °C) and the
freezer cools to 21.2 °f (- 6 °C) in opt imum
cooling cond itions . Th e cooling performance
is affected by the temperature in the luggage
compartment. The temperature inside the
cooler will be higher if the luggage compart­ ment is hot.
A WARNING
To avoid putting the occupants at any risk, please observe the following safety rules:
- The maximum capacity is 2.5 kg (5.5
lbs.).
- Never overload the cooler. This could cause injury in the event of a collision or
sudden braking.
- The coo ler lid must always be kept closed
while you are driving. Make sure the re­
taining catch is securely engaged . The
contents of the coo ler could be thrown
forward into the passenger compart­
ment in the event of a collision or under
sudden braking - risk of injury!
- Inflammable liquids, gas canisters, etc.
must not be stored in the cooler -risk of
exp losion! This also includes any prod­
ucts that might emit volatile or inflam­
mable gases.
- Liquids will freeze at temperatures at or
below 32 °f (0 °C) and may cause glass
bottles to burst!
Seats and storage 77
(D Note
-The venti lation openings for the cooler
are located on the back pane l trim in the
