& WARNING
• The ski sack is intended only for the transportation of skis 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 102, fig. 108.
[ i] Tips
Never stow the ski sack away when it is still wet or damp (for
example, snow melting from skis). Allow i t to dry completely before
stowing it away. •
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 a roof rack or similar luggage carrying equipment is to be
installed, please note the following:
• To enhance the vehicle's streamlined design, rain gutters have
been molded into the roof. It is not possible to use normal roof
racks. Only install a roof rack specifically designed for your model
A8. Contact the nearest Audi dealer for information on approved modular roof racks for your vehicle.
Controls and equip­
ment
• 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
authorized Audi dealer.
• We recommend that you keep the installation instructions for
your roof rack system together with your Owner's l iterature 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 consumption, wind noise and to
guard against theft.
& WARNING
• Use of an unapproved roof rack or incorrect mounting of an
approved roof rack can cause the roof rack or the items attached
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 system between the markings shown in
~ page 104, fig. 109.
• The roof rack system must be installed exactly according to the
instructions provided.
(D Note
• Your vehicle warranty does not cover any damages to the vehicle
caused by using roof racks or mounting struc tures 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 during a trip to make sure everything is securely tightened.

In some situations you will have to use the foot brake and slow the
vehicle down to keep a safe distance to vehic le in front of you or to
avoid a rear -end co llision.
Pas sing anot her ve hic le
I f you move into the passing lane and no vehic le is detected ahead,
Adaptive Cruise Contro l accelerates to the speed you have set and
maintains it.
O verr ide
You can increase your speed a t any time by stepping on the acceler­
ator pedal. After you release the accelerator pedal, the system auto­
mat ically adjusts back down to the speed you previously set.
[ i J Tips
Please note that the amount of acceleration the Adaptive Cruise
Control uses depends on the Distance setting selected . DISTANCE 1
gives you acceleration that is dynamic and sporty . D IS TA NCE 4, on
the other hand, gives more moderate acce leration . You can find a
detailed description of the "time

Adaptive Air Suspension and
Damping
Description
Adaptive Air Suspension and damping can be regulated
and they adapt automatically to a request from the driver
and the driving situation at the time.
Adaptive Air Suspension is an electronica lly contro lled springing
and damping system. T his chassis system makes it eas ier on the
driver by adapting to the particu lar situation through imperceptible
control processes.
The
Ad apti ve Air Suspen sion component regu lates ground c lear­
ance depending on vehicle speed, load condition and driver input .
Acce lerat ing to a speed above a predetermined limit wil l make the
vehic le lower i tself. On the other hand, driving more slowly results
in the vehic le rais ing again at specific speeds .
T he
d amp in g component provides individual contro l of the
damping forces. For examp le, 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
over rough road surfaces as well as when brak ing.
S ett ing s
Adaptive Air Suspension provides the driver with the opportunity to
set the chassis characteristics a lso to their individua l preference .
With the driving modes
standard, automatic and dynamic the driver
has three chassis settings availab le, ranging from comfort to sporty.
In addition,
lift provides a fourth mode wh ich can be selecting for
driving over poor stretches of
road~ page 186, "Chassis Contro ls" .
The modes are se t in MMI
~ page 188.
Controls and equip­ ment
On vehicles equipped with the sport su sp en sion Adaptive Air
Suspension -Sport *, there is genera lly more emphasis on a sporty
chassis sett ing. Settings range from comfortable to firm
~ page 187, "Sport Chassis Contro ls".
0 Note
• Whenever you park your vehicle, always make sure there is
adequate c learance above and be low the vehicle . The height of the
parked vehicle can change as the result of temperature fluctuations,
changes in l oad condition and c hanges in the driv ing m ode (ground
c learance).
• Mount the tie -down cha ins/cab les over the running surface
(circumference) of the tires . Never secure the vehicle by the axle, the
suspens ion stru ts or the front or rear towline eye . For tec hn ica l
reasons , the pressure in the suspension struts may change during
the transport and this wil l adversely affect vehicle handling.
• To prevent damage to the vehic le underbody, remember that
your vehicle is not a n off -road vehicle, even in the lift mode . The
ground clearance is insufficient for this type of operation .
• If you are going to tow a tra iler, you mus t activate the trailer oper ­
ation
mode~ page 189 .
[ i ] Tip s
Before you can raise your vehic le using the vehicle jack (for
examp le, when changing a flat tire) you must activate the jacking
mode
~ page 188 . •

Chassis Controls
Four different driving modes can be set by the driver.
The automatic control processes are speed -and time -dependent.
For example, it is not possible to raise the suspension to the lift
mode above certain speeds .
When a speed of about 75 mph (120 km/h) is exceeded for more than 30 seconds, the vehicle is automatically lowered approximate ly 1
inch (25 mm) to a level suitable for highway speeds, except in the
standard mode . Road holding is optim ized as a result of the lower
center of gravity and fuel consumption is reduced as a result of
reduced wind resistance .

Child Safet y -
---------------''----
(The term "ISO FIX" regarding lower anchorages had been used by
Audi and other manufactu rers in the past, but LATCH is now the
standard name for the new child restraint anchorage system.)
Some child restraint system manufacturers have been providing
tether straps on certain mode ls of their child restraint systems,
either as standard equipment or as a retrofit, for several years .
Check with the manufacturer of the ch ild restraint system for tether
strap availability .
To provide a simpler and more practicable way to attach the child restraint system on the vehicle seat, U .S . Federal regulations require
the phase -in of lower anchorages in vehic les and devices on new
ch ild restraint systems to attach to the veh icle anchorages.
Child restraint system manufacturers will probably offer two kinds
of lower anchorages on their child safety seats
T hey could come with:
• hooks or other latches attached to adjustable straps or
• rigid latches on bars tha t extend out the back of the child
restraint and are released with release but tons at the bottom of the
child restraint.
In addition to the LATCH lower anchorages, both of these chi ld
restra int systems use tether straps to he lp keep the ch ild restraint
system firmly in place .•
Where can I get additional information about
child restraint application and usage?
There are a number of sources of additional information about child
restra int select ion , instal lat ion and usage :
NH TSA advises that the bes t child saf ety seat is the one that fits
your ch ild and fits in your ve hicle, and that you wi ll use correctly and
consistent ly.

- Lack of proper maintenance as wel l as improper use of the
vehic le will impair the func tion of the emission con tro l system
and cou ld lead to damage .
<£> For the sake of the envir onment
Even when the Emission Control System is operating properly, the
exhaust gas can have a su lfur -like exhaust gas smell under some
operating states . This depends on the sulfur content of the fuel
being used. Using a different b rand of fue l may help, or fil ling the
tank with lead-free super grade gasol ine. •
Avoid damaging the vehicle
When you are driving on poor roads, or over curbs, steep ramps,
etc., make certain that low- lying parts such as spoi lers and exhaust
system parts do not bottom out and get damaged.
T his is especial ly true for vehicles with low -s lung chassis (sports

Operate your vehicle economically
and minimize pollution
General
Y o ur personal style of driving will determine the economy
of your vehicle , as well as exhaust and noise levels.
Fuel economy, environmenta l impact, and wear on your engine,
