& WARNING
• The ski sack is intended only for the transportation of skis,
snowboards and other light objects. To reduce the risk of serious
personal injury never transport heavy or pointed objects in the ski
sack.
• When braking rapidly or during an accident the load could be
displaced and cause injury to occupants.
• Sharp edges on the load must be covered for protection.
Always fasten the belt tightly around the sack and its contents
=> page 111, fig . 114.
[ i] Tips
Never stow the ski sack away if it 's wet or damp (for example, snow

Roof rack
First things first
A roof rack can be fitted to carry additional luggage on
the roof.
Always read and follow the instructions provided by the
roof rack manufacturer when the roof rack system must
be installed.
If you are transporting luggage or other objects on the roof, please
note the following :
• Your vehicle has specially designed aerodynamic roof rails. Only
install a roof rack specifically designed for your model. Contact the
nearest authorized Audi dealer for information on approved
modular roof racks for your vehicle.
• These approved roof racks are the basis for a complete roof rack
system. Additional attachments for the basic roof rack are neces­
sary to safely transport luggage, bicycles, surf boards, skis or small
boats . All necessary hardware for these systems is available at your
authori zed Audi dealer .
• We recommend that you keep the installation instructions for
your roof rack system together with your Owner's literature in the
vehicle.
When should the roof rack be removed?
• 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. _.,,

& WARNING
• Use of an un appr oved roof ra ck or in correct mounting of an
approved roof ra ck can c aus e the roof ra ck or the item s attached
to it to fall off the r oof ont o the ro ad .
• Object s falling fr om the roof of a vehi cle can c ause a crash and
p ers onal inju ry.
• Only mount the sy ste m between the marking s shown
in
=> fig. 115 .
• The roof rack sy ste m mu st b e in sta lled e xactly a ccording to the
instructions prov ided .
0 Note
• Your vehicle warranty does not cover any damages to the vehicle
caused by using roof racks or moun ting structures no t approved by
Audi for your vehicle . T he same app lies to damage resulting from
incorrect roof rack installation .
• Always check the roof rack mountings and hardware before each
t rip and during a trip to make sure everything is securely tightened.
If necessary, retighten the mountings and check the entire system
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 vehicle is natu­
ra lly increased . Be carefu l when driving under low bridges or in
parking garages for exa mple . This cou ld cause damage to the load
and even the vehicle itself .•
Con tro ls and eq uip­
ment
Roof rack mounting locations
Roof racks must be installed only at the locati ons marked
on t he roof rails .

mountin g locations
Mount the front and rear cross bars between the punched markings
on the inside of the roof railings => fig . 115. The markings are
located on the inside of the rail ings .•
Loading the roof rack
Always di stribute loads evenly. Make sure anything on the
ro of ra ck is securel y tied down.
Always d istr ibute the loads o n the roof rack even ly .
Always attach items to the roof rack secure ly before you
drive off .
The maximum permissible roof weight is 220 lb 1100 kg ). The roof
we ight is made up of the weight of the roof rack system and the
weight of the object being transported .
When using a roof rack system which has a lower load carrying capacity, you must not use up the tota l maximum permissible load
carrying capacity specified above. Instead, you should load the roof

rack syst em only to the maximum capaci ty spec ified by the manu ­
f actu rer of the roo f ra ck sy stem.
& WARNING
Weak , damaged or improper straps used to secure items to the
roof rack can fail during hard brak ing or in a collision and cause
serious personal injury.
• Make sure the roof rack is installed exactly as spe cified above
~ page 113 .
• Always use suitable mounting straps for securing items to the
roof rack to help prevent items from shifting or flying forward .
• Items on the roof rack must always be securely mounted .
• The use of a roof rack can negatively affect 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 gravity and overall handling . Always drive slowly, avoid sudden
braking and maneuvers when t ransporting cargo on the roof of
your vehicle.
• Never exceed the maximum permissible load carrying capacity
of the roof of your vehicle , the permissible axle weights and the
perm issible total weight of your vehicle~
page 397, "Weights ".
• Always drive slowly , avoid sudden braking and maneuvers
when transporting cargo on the roof of your vehicle.
0 Note
M ake sure that the opened rear lid does not come in contact with
the ca rgo on the roof.
~ For the sake of the environment
Sometimes it may be easier to leave a roof rack installed eve n
th ough you a re not usi ng it. Due to th e increased a ir resis tanc e your
veh ic le wi ll unnecessarily u se more fue l. Remove the roof rack if you
are no t go in g to us e it.•

& WARNING
• Never turn off the engine until the vehicle has come to a
complete stop.
• The brake booster and servotronic only work when the engine
is running. With the ignition turned off, you have to apply more
force when steering or braking. Since you cannot steer and stop
normally, this can lead to accidents and serious injuries.
• For safety reasons, you should always park your vehicle with
the selector lever in P. Otherwise, the vehicle could inadvertently roll away.
• After the engine has been switched off, the radiator fan can
continue to run for up to 10 minutes -even with the ignition
switched off. It can also switch on again after some time if the
coolant temperature rises as the result of a heat buildup or if the
engine is hot and the engine compartment is additionally heated
by the sun's rays.
0 Note
If the engine has been under heavy load for an extended period,
heat builds up in the engine compartment after the engine is
switched off -there is a risk of damaging the engine. Allow the
engine to run at idle for about 2 minutes before switching it off. •

This message appears when the [STAR T) button is pressed if there
is no master key inside the vehicle or if the system does not recog­
nize it . For example, the master key cannot be recognized if it is
covered by an object (e.g. aluminum brief case) which
screens the radio signal. Electronic devices such as cell phones can also inter­
fere with the radio signal.
Press brake pedal to start engine
This message appears if you press the [ START) button to start the
engine and do not depress the brake pedal. The engine can only be
started if the brake pedal is depressed.
Engage N or P to start engine
This message appears when the engine is started if the selector
lever for the automatic transmission is not in the P or N position.
The engine can only be started with the selector in these positions.
? Key not in vehicle
This message appears along with the symbol if the master key is
removed from the vehicle with the engine running. It is intended to
remind you (e.g. when changing drivers) not to continue the journey
without the master key.
If the master key is no longer in the vehicle, you cannot switch off
the ignition after stopping the engine and you also cannot start the engine again. Moreover, you cannot lock the vehicle from the
outside with the key.
Shift to P, otherwise vehicle can roll away. Doors do not lock if lever
is not in
P.
This message appears for safety reasons along with a warning
buzzer if the selector lever for the automatic transmission is not in
the P position when the ignition is switched off with the
[STOP)

m aneuv ers by i tse lf ; t he driver m ust alw ays app ly the b rake s.
& WARNING
If ACC initiates a braking maneuver, the brake pedal will be
retracted . Interference with the brake pedal can prevent ACC from
slowing the vehicle down and cause a crash and serious personal
injury .
• Never put anything in the driver 's footwell or let anything fall
into it . An object in the driver 's footwell can interfere with the
pedals and prevent the accelerator from being used to override
ACC or prevent ACC from being swit ched off when the brake pedal
is depressed and also prevent the vehicle from being slowed down
or stopped .
• Only u se floor mats that keep the area around the pedals free
and that can be securely fastened to the footwell.
• Never drive with your foot underneath the brake pedal.
• Always read and heed the information and WARNINGS=>
& in
" Description " on
page 152.
& WARNING
• Never rely on the distance control feature of ACC alone to
prevent rear -end collisions. Always be prepared to brake and take
evasive action to avoid collisions and other accident situations .
• Never allow the closing speed between you and other vehicles
to be so high that the Adapt ive Cruise Control may not be able to
slow your vehicle safely .
If closing speed is too high , you must
apply the brakes yourself to reduce the risk of a rear -end cra sh.
[ i ] Tips
Please note that the amount of acceleration the Adaptive Cruise
Control uses depends on the Distance setting selected. DISTA NCE 1

Adaptive Air Suspension
Air suspension and damping
Applies to vehicles: with Adaptive A ir Suspens ion
Description
Air suspension and damping can be regulated as desired
by driver, and they adapt automatically to the driving situ­
ation at the time.
Adaptive Air Suspension is an electronica lly contro lled springing
and damping system. This chassis system makes it easier on the
driver by adapting to the particular situation through imperceptible
control processes.
The
Adaptive Air Suspension component regulates ground clear ­
ance depending on vehic le speed and driver inpu t. It functions inde­
pendently from the load condition. Accelerating to a speed above a
predetermined limit will make the vehic le lower itself . On the other
hand, driving more slowly results in the vehicle raising again at
specific speeds.
The
damping component provides individual control of the
damping forces. For example, with damping characteristics set to
provide greater comfort, damping is set somewhat harder for a brief
period only as required, for example, when going around a curve or
when braking.
Settings
Adaptive Air Suspension prov ides the driver with the opportunity to
set the chassis characteristics a lso to their individual preference.
With the driving modes
comfort, automatic and dynamic the driver
has three chassis settings available, ranging from comfort to sporty.
The
offroad mode can be selected for driving on poor qua lity
stretches of road. In addition, lift provides a fifth mode, which can
be selected when exceptionally high ground clearance is needed
=> page 207, "Chassis controls". The modes are set in
MMI:::::,
page 208.
& WARNING
The height of the parked vehicle can change due to temperature
fluctuations or changes in load.
0 Note
• Whenever you park your vehicle, always make sure there is
adequate clearance above and below the vehic le. The height of the
parked vehicle can change as the result of temperature fluctuations,
changes in load condition and changes in the driving mode (ground
clearance!.
• If the vehicle is being transported (e.g. by tow truck, train, ship,
etc.), mount the tie -down chains/cables over the running surface
(circumference) of the tires . Never secure the veh icle by the axle, the
suspension struts or the front or rear towline eye. For technical
reasons, the pressure in the suspension struts may change during
the transport, which could result in the vehic le no longer being
secured properly.
• If you are going to tow a trailer with a trailer hitch that was
not
installed according to factory specifications, you must activate the
trailer operation mode manually:::::,
page 211.
[ i ] Tips
• Before you can raise your vehic le using the vehicle jack (for
example, when changing a flat tire) or a vehicle lift, you must acti­
vate the jacking mode:::::,
page 210.
• On some models, the vehicle can reach its maximum speed only
in the
automatic and dynamic modes. •
