-Your vehicle warranty does not cover any
damages to the vehicle caused by using
roof racks or mount ing structures not
approved by Audi for your vehicle . The
same applies to damage resulting from i ncorrect roof rack installation .
- Always check the roof rack mountings
and hardware before each trip and dur ­
i ng a tr ip to make sure everythi ng is se­
curely 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
is natura lly increased . Be careful when
driving under low bridges or in parking
garages for example. This could ca use
damage to the load and even the vehicle
i tself.
- Make sure the open rear lid and the sun­
roof* do not come into contact with the
roof rack .
Loading the roof rack
Always distribu te loads evenly. Make sure
any thing on the roof rock is securely tied
down .
.. Always distribute the loads on the roof rack
evenly .
.. Always attach items to the roof rack securely
before you drive off .
The maximum perm iss ible roof weight is
220 lb (100 kg ). The roof weight is the to tal
of the weight of the roof rack, the attach ­
ments and the cargo you are carrying . 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 pe rm iss ib le load ca rry­
ing capacity specified above. I nstead , you
should lo ad the roof rack sys tem only to the
S eat s an d sto rage 73
maximum capacity specified by the manufac ­
turer of the roof rack syst em.
A WARNING
Weak , damaged or improper straps used
to secure items to the roof rack can fail
during hard braking or in a coll is ion and
cause ser ious persona l injury .
- Make sure the roof rack is installed exact­
ly as specif ied above
c> poge 72.
-Always use s uitable mount ing straps for
secur ing items to the roof rack to help
prevent 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 infl uence on
the vehicle's aerodynamics, center of grav ity and overall handling. Always
drive s lowly, avoid s udden braking and
maneuvers when transporting cargo on
the roof of your vehicle.
- Never exceed the maxim um permissible
load carrying capacity of the roof of your
vehicle, the permissible axle weights and the permissible total weight of your vehi­
cle
c> page 287, Weights.
@ For the sa ke of the environment
As a result of the increased wind resist­
ance created by a roof rack, your vehicle is
u s ing fuel unnecessarily . So remove the
roof rack after using it .

_& 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 over load the cooler. This could
cause injury in the event of a co llision 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 cooler could be thrown
forward into the passenger compart­
ment in the event of a collision or under
sudden braking - risk of in jury!
- 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
mab le gases.
- Liquids will freeze at temperatures at or
below
32 °F (0 °C) and may cause glass
bottles to burst!
(D Note
- The ventilation openings for the cooler
are located on the back panel trim in the
l uggage compartment and
must be kept
clear at all times.
- If the cooler is not functioning properly,
switch it off to prevent further damage.
Have it checked by a qualified workshop .

(D Tips
- Always try to leave the lid open for as
short a time as possible to prevent con­
densation buildup.
- Do not put hot food or dr inks in the cool­
er.

140 Driving Safely
-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
missible weight standards can cause the
vehicle to slide and handle differently.
- Please observe information on safe driv­
ing
q page 133.
A 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
area because the rear lid cannot be fully
closed.
- If you absolutely must drive with the rear
lid open , observe the following notes to
reduce the risk of poisoning:
- Close all windows,
- Close the power roof,
- Open all air outlets in the instrument
panel,
- Switch off the air recirculation,
- Set the fresh air fan to the highest
speed.
A WARNING
Always make sure that the doors, all win­
dows, the power roof and the rear lid are
securely 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, on the
Left side of the Luggage compartment.
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
¢ page 249.
Tie-downs
The luggage compartmen t is equipped wi th
four tie-downs to secure luggage and o ther
items.
Use the tie-downs to secure your cargo p rop­
erly ¢
page 139 , Loading the luggage com­
partment.
In a collision, the laws of physics mean that
even smaller items 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

24 6 T ire s and whee ls
- Never mount used tires on yo ur vehicle if
you are not sure of their "previous histo­
ry." Old used tires may have been dam­
aged even though the damage cannot be
seen that can lead to sudden tire failure
and loss of vehicle control.
- If you notice unusual vibration or if the
vehicle pulls to one side when driving, al­
ways stop as soon as it is safe to do so and check the wheels and tires for dam­
age.

Cold tire inflation pressure
Tire pressure affects the overall handling, performance and safety of a vehicle.
Fig. 208 Tire pressure label: located on driver 's side B­
pillar
Tire pressure generally refers to the amo unt
of air in a tir e that it needs it to do its job and
safely carry the combined load of the entire
vehicle and its contents . Tire pressure is
measured in kilopascals (kPa), the interna ­
tional measuring unit and in pounds per
squa re inch (PSI). Tire pressure is based in
part on the vehicle's design and load limit -
the greatest amount of weight that the vehi­
cle can carry safely and the tir e size. The prop­
er tire pressure is frequent ly referred to as the
"recommended cold tire inflation pressure ."
Air in the tires expands when the tire heats up
because of internal friction when it flexes in
use. The tire p ressure is higher when the tire
has warmed up than when it is "cold." It is the
inflation pressure in a "cold" tire that counts.
Therefore, you should never let air out of a
warm tire to match "cold tire inflation p res­
sure" recommendations. The tir es would then
be underinflated and could fail suddenly .
Maintaining proper tire pressure is one of the
most important things you can do to help
avoid sudde n tire failure . Underinflated tire s
are a major cause of sudden tire failure. Keep­
in g tires at the right pressure is also impor-

tant for safe and respons ive ve hicle hand ling,
traction, braking and load carrying.
Tire pres­
sures are particularly important when the
vehicle is being driven at higher speeds, and
then especially when heavily loaded even
within the permissible load-carrying capaci­
ties approved for your vehicle.
The recommended tire pressures for your Audi
depend on the kind of tires on your vehicle
and the number of passengers and/or amount
of luggage you will be transporting.
The tire pressure label is located on the driv­
er's side B-pillar. The tire pressure labe l lists
the recommended cold tire inflat ion pressures
for the vehicle at its maximum capacity
weight and tires that were on your veh icle at
the time it was manufactured.
If you wish to improve comfort when operat­
ing the vehicle at normal load (up to 2*/3
occupants), you can adjust tire pressures to
those specified for normal vehicle load. Be­
fore operating the vehicle at maximum load,
you must increase the tire pressures to those specified for maximum vehicle load

250 Tires and wheels
Bear in mind that the tire pressure monitoring
system* can only monitor the tire pressures
you have stored . The system does not recog­
nize the load condit ion of your vehicle.
The effectiveness of the tire pressure monitor ­
ing system* will be impaired if you store nor­
mal load pressures but then operate the vehi ­
cle at its max imum load

See the illustration c:> fig. 208 for the location
of the label on driver's side B-pillar (color of
the act ua l label and exact location on the ve­
hicle will vary slightly). Note
that the following table is accurate at
the time of going to press and is subject to
change. In the event of d iscrepancies, the t ire
pressure label is located on the driver's side B­
pillar always takes precedence.
The table below lists the recommended cold
