road surface is icy or not . Keep in mind
that road surfaces, especially bridges
and overpasses, could be ice covered and
slippery even at an outside temperature
above 41 °F (+S °C).
- Always remember, even if the "snow­
f lake" symbo l (ice warning) does not ap­
pear in the display, black ice could be on
the road.
- Always reduce your speed and drive with
special care in cold weather conditions
when the chance of encountering icy
road surfaces increases.
(D Tips
-If the vehicle is stationary, or if you are
driving at a very low speed, the tempera­
ture shown in the display might be
slightly h igher than the actual outside .,,.

In a co llision, t he laws o f physics mean that
even smaller items that a re loose in the vehi­
cle w ill become heavy missiles that can cause
serious injury. Items in the vehicle possess en­
ergy wh ich vary with vehicle and t he weight of
the item. The veh icle speed is the most s ignif ­
icant factor .
For example, in a frontal collision at a speed
of 30 mph (48 km/h), the forces acting on a 10 lbs (4,5 kg) object are about 20 times the
normal weight of the item . This means that
the weight of the item wou ld sudden ly be
about 2 00 lbs (90 kg). You ca n imagine the in­
j u ries tha t a 200 lbs (90 kg) item flying free ly
t hr ough the passenger comp artment cou ld
ca use in a co llision like this .
_& WARNING
Weak, damaged or improper straps used
to secure items to fasten ing eyes can fai l
d uring hard braking or in a coll is ion and
cause ser ious personal injury. -
-A lways use s uitable mount ing straps an d
properly secure items to the fasteni ng
eyes in the luggage compartment to help
prevent items from sh ifting or flying for-
~~-~

-When the rear seat backrest is folded
down, always use su itable mounting
straps and properly secure items to the
fastening eyes in the luggage compart­
ment to help prevent items from flying
forward into the passenger compart­ ment.
- Never attach a child safety seat tether
strap to a fastening eye.

Roof rack* installation
First things first
A roof rack can be used to carry additional
luggage on the roof There are two different
roof rack systems .
Separate roof racks are needed for vehicles
without roof rails . Vehicles with standard roof
rails* need add itional cross bars to carry car­
go . Both types of add itiona l equipment are
available at your authorized Audi dealer.
~ Always read and follow the instructions pro ­
vided by the roof rack manufacturer when
the roof rack system must be installed.
If a roof rack or s imilar luggage carrying
equipment is to be installed, please note the
fo llow ing :
Vehicles without roof rails
- Your vehicle has aerodynam ic rain gutters
molded into the roof. That is why only roof
racks specially designed for the roof can be
used . We recommend using roof racks from
the Audi original accessories program .
- These roof racks are the basis for a complete
roof rack system . For safety reasons, some
additional attachments are necessary to
transport luggage, bicycles , surf boards,
skis and small boats safely. A ll these com­
ponents are available at your authorized Au­
di dea ler .
Vehicle with roof rails
-The vehicle is equipped with integrated roof
railings,
which can be covered into roof rack
by ins tal ling c ross bars . Only install cross
bars specifica lly designed for this vehicle.
- These bars are the basis for a complete roof
rack system . Additional attachments are ..,.

7 2 Seats and storage
necessary to safely trans port luggage,
bicycles, surf boards, skis or small boats.
- All necessary hardware for these systems is
available from yo ur authorized Audi dealer.
When should the roof rack b e removed ?
-Before go ing through an automatic car wash
(it is bes t to ask the car wash opera to r)
- When not in use ( reduce fuel consumpt ion,
reduce wind noise and gua rd against theft)
_& WARNING
- Use of an unapproved roof rack or in cor­
rect mo unt ing of an app roved roof rack
can cause the roof rack o r the items car­
ried on it to fall
off the roof onto the
road.
- Objects falling from the roof of a ve hicle
can cause a c rash and persona l injury.
- Only mount the system between the markings shown in
r=> page 72, fig . 83
or r=>page 73, fig. 84.
-The roof rack system must be insta lled
exactly according to the instr uctions pro­
vided.
(D Note
- Any damage to the veh icle ca used by us­
ing roof racks or other types of cross bars
that have not been approved by Audi for
your vehicle, or incorrect roof rack instal­
l ation, is not covered by the Warranty.
- Always check the roof rack mount ings
and hardware before each trip and dur­ i ng a tr ip to make sure eve rything is se­
curely tightened . If necessary, retighten
the mount ings and check the ent ire sys­
tem from t im e to t im e.
- After mounting a roof rack system, or when you transport objects on the roof
of your veh icle, the height of the v ehicl e
i s n atur ally in creased. Be care ful when
driving u nder low br idges or in pa rk ga­
rages for example. This could cause
damage to the veh icle and even the loa d.
