"Read and heed all WAR NINGS 9 page 139,
Stowing luggage .
In a collis ion, the laws of phys ics mean that
even smaller items that are loose in the vehi­
cle will turn into heavy missiles that can ca use
serious in jury . Items in the vehicle pick up ki­
netic energy which varies w ith the vehicle and
the weight of the item . Vehicle speed is the
most signif icant factor.
F or example, in a frontal coll is ion 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 we ight of the item would suddenly be the equivalent of about 200 lbs (90 kg). One can
easily imagine the injuries that an
item of that
weight flying freely through the passenger compartment can cause in a collis ion at a
speed considered relatively low .
A WARNING
-Weak, damaged or imprope r straps used
to secure items to tie-downs can fail dur­ in g hard braking or in a collision and cause
se rio us personal injury.
- Always use su itable reta ining straps a nd
p roperly secu re items to the tie-downs in
the l uggage compa rtment to he lp pre­
vent i tems from shift ing or fly ing fo r­
ward.
- Never at tach a chi ld seat tether strap to
a t ie -down.
- For s trength-re lated reasons, the mou nt­
ing hooks can only be used to secure ob­
jects weighing up to 10 lb. (5 kg) . Heavi ­
er objects will not be adequately sec ured
- there is a risk of injury.

A WARNING ... -
-The ski sack is intended only for the
transportation of skis and other light ob­
jects. To reduce the risk of ser io us per­
sonal injury, never transport heavy or
pointed objects in the ski sack.
- When braking rapidly or during an acci­
dent, the load could be disp laced and
cause injury to occupants.
- Sharp edges o n the load must be covered
for protection. Always fasten the belt
tightly around the sack and its contents. _...

7 2 Seats and storage
-For safety reasons, do not transport
more than two pairs of skis in the ski
sack.
- You must secure the ski sack with the
strap after loading.
- Make sure all objects that you are trans­
porting in the pass-through are secured.
Otherwise they could slide around during
sudden braking maneuvers and cause in­
jury.
Q) Tips
- Never stow the ski sack away when it is
still wet or damp (for example, snow
melting from skis). Allow it to dry com­
pletely before stowing it away .
- Position skis in the ski sack with the
pointed ends facing the front and ski
poles with the pointed ends facing the
rear.
Roof rack
Description and mounting locations
Additional cargo can be carried with a roof
luggage rack.
Fig. 77 Roof rack attac hment points
,. Always read and follow the instructions pro­
vided by the roof rack manufacturer when
installing the roof rack system .
If luggage or cargo is to be carried on the
roof, you must observe 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 AB. Contact the nearest Audi
dealer for information on approved modular
roof racks for your vehicle.
- Only use roof racks approved for your vehi­
cle. These approved roof racks are the basis
for a complete roof rack system. Additional
attachments or carrier systems are needed
to transport luggage and sports equipment.
We recommend using roof racks from the
Audi original accessories program .
- When installing the roof rack, make sure it
is only mounted on the designated locations
on the roof~
fig. 77 .
- We recommend that you keep the installa­
tion 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 .
8,. WARNING
-Use of an unapproved roof rack or incor­
rect mounting of an approved roof rack
can cause the roof rack or the items at­
tached 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 roof rack on the desig­
nated locations on the roof¢
fig. 77.
- The roof rack system must be installed
exactly according to the instructions pro­
vided.
- When driving with a roof rack system,
changes to the center of gravity and wind
resistance can change the vehicle han­
dling and lead to a collision. Always
adapt your driving and your speed to the
current conditions.
