The valet key fits only the driver's door and the ignition lock. If you
have to leave the key with somebody else, you are well-advised to
turn over the valet key only.
Be aware that the rear lid can be opened from inside the vehicle with
the remote rear lid release located in the driver's door. Before you
turn over the valet key you should therefore lock the rear lid
mechanically with the master key.
Turn the master key
clockwise to the horizontal position and pull it
out . This has two effects:
• the
remote rear lid release is deactivated,
• the lid will remain locked when the power locking system is actu­
ated.

Luggage compartment
Tie-down eyelets
The luggage c ompartment is equipped with four tie -down
eyelets to secure luggage and other items.

-Use the tie-dow n eyelets to secure yo ur cargo properly
=:> fig . 104 -arrows- .
-Read and heed all WARNINGS =:> page 205, "Stowing
luggage" .
In a collision , the laws of physics mean that even smaller items that
are loose in the vehicle will turn into heavy missiles that can cause
serious injury. Items in the vehicle pick up kinetic energy which
varies with the vehic le 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 i tem . This means that the weight of the item
would suddenly be the equivalent of about 200 lbs (90 kg). One can
easily imagine the injuries that an i tem of tha t weight flying free ly _,,,

through the passenger compartment can cause in a collision at a
speed considered relatively low.
& WARNING
Weak, damaged or improper straps used to secure items to tie­
downs can fail during hard braking or in a collision and cause
serious personal injury.
• Always use suitable retaining straps and properly secure items
to the tie-downs in the luggage compartment to help prevent
items from shifting or flying forward.
• Never attach a child seat tether strap to a tie-down. •

• 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.

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

• Alway s use suitable m ounting strap s for securing it e ms t o the
