& 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

[ 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.
~

--~S~e~ a~t ~s ~a~n~d~ s~t~ o~r~ a:!Jg~ e:._ _____________________________________________ _
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 careful when driving under low bridges or in
parking garages for examp le. This cou ld cause damage to the load
and even the vehicle itself. •
Mounting locations
Safe installation of a roof rack requires that the rack
sup ports are m ounted between the small arrows marked
inside the door frames on all four doors .
Mounting
Fig. 1 09 Front and r ear
ma rkings
Th e roof r ack sy stem mu st be in stalled exactly according to th e
i n stru ction s prov ided .
Mount the roof racks suppo rts in the side roof moldings. Make sure
to position the supports on
all four doors between the points
marked by small
arrows => fig. 109. The markings can only be seen
when the doors are open . •
Loading the roof rack
Always distribute loads evenly. Make sure anything on the
r o of rack 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.
T he maximum permissible roof weight is 220 lb (100 kg ). The roof
we ight is made up o f the weight of the roo f 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 total maximum permissible load
carrying capacity specified above . Instead, you should load the roof
r ack system only to the maximum capacity specified by the manu ­
facturer of the roof rack system .
& WARNING
Weak, damag ed or improper str ap s used to secur e item s to the
r o of rack can fail du ring hard b raking o r in a colli sion and c ause
s eriou s per sonal injur y.
• Make sure the roof rack i s in stalled exactly as s pecifi ed abo ve
=> page 104 .
• Alway s use suitable m ounting strap s for securing it e ms t o the
r o of rack to help prevent item s from shiftin g or fly ing forward.
• Items on the r oof rack mus t al w ay s be se curel y mo unted .
• The u se of a roof r ack can n egatively affect the way a v ehicle
hand les . C arg o that i s la rge , he avy, bulky , long or fl at will h ave a
greater ne gative influence on the vehicle' s aerodyn amics, center
of grav it y and o verall handli ng. Alw ays dri ve slowl y, avoid sudden
braking and maneuver s when tr ansp orting carg o on the roof of
yo ur vehicle . ...,

[ i J Tip s
If the climate control system is operating in cool ing mode, air flows
primarily from the outlets in the center console and in the door
pillars . To achieve adequate cooling, you should never close the
out lets completely. •
Using climate controls economically
Using the climate controls prudently can help save fuel.
When you use t he a ir conditioner, engine power is reduced
and fuel consumption increases. To save fuel, you should
use the a ir co nditioner only when necessary. Also please
note the follow ing po ints:
- If you want to save fuel, activate ECON.
If you are going to drive with the windows open, use ECON.
W For the s ake of the environm ent
By reducing the amount of fuel you use, you also reduce the amount
of pollutants emitted into the air. •

& WARNING
Improperly stored luggage or other items can fly through the
vehicle causing serious personal injury in the event of hard braking
or an accident. To help reduce the risk of serious personal injury:
• Always put objects, for example, luggage or other heavy items
in the luggage compartment.
• Always secure objects in the luggage compartment using the
tie-down hooks and suitable straps.
& WARNING
Heavy loads will influence the way your vehicle handles. To help
reduce the risk of a loss of control leading to serious personal
injury :
• Always keep in mind when transporting heavy objects, that a
change in the center of gravity can also cause changes in vehicle
handling:
-Always distribute the load as evenly as possible.
- Place heavy objects as far forward in the luggage compart-
ment as possible.
• Never exceed the Gross Axle Weight Rating or the Gross
Vehicle Weight Rating specified on the safety compliance sticker on the left door jamb. Exceeding permissible weight standards
can cause the vehicle to slide and handle differently.
• Please observe information on safe
driving => page 198.
& 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.
& WARNING (continued)
• 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.
& WARNING
Always make sure that the doors, all windows, 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 especially 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.
[ i] Tips
Air circulation helps to reduce windowfogging. 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. •
