• These approved roof racks are the basis for a complete roof rack
system . Additional attachments for the basic roof rack are necessary
to safely transport luggage, bicycles, surf boards, skis or small boats .
All necessary hardware for these systems is ava ilable at your autho ­
rized Audi dealer .
• We recommend tha t you keep the installation 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 automat ic car wash (it is best to ask the
car wash operator fo r advice)
• When not in use, to reduce fuel consumpt ion, wind nois e 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
=> fig. 98.
• The roof rack system must be installed exactly according to the
instructions provided.
0 Note
• Your vehicle warranty does not cover any damages to the vehicle
caused by using roof racks or mounting structures not approved by
Audi for your vehicle . The same applies to damage resulting from
incorrect roof rack installat ion .
• Always check the roof rack mountings and hardware before each
trip and dur ing a trip to make sure everything is sec urely tightened . If

necessary, ret ighten 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 veh icle, the height of the vehicle is naturally
increased. Be careful when driving under low bridges or in parking
garages for example. This could cause damage to the load and even
the vehicle itself . •
Mounting Locations
Safe installation of a roof rack requires that the rack
supports are mounted between the small arrows marked
inside the door frames on all four doors.

The roof rack system must be installed exactly according to the
instructions provided.
Mount th e roof racks supports in the side roof mo ldings . Make sure

Seats and storage Loading the roof rack
Always dis tribute loads evenly . Make sure anything on
the roof rack is securely tied do wn.
- Always distribute the loads on the roof rack evenly .
- Always attach items to t he roof rac k securely before you
drive
off .
The maximum permissible roof weight is 220 lb (100 kg ). The roof
we igh t is made up of the weight of the roof rack system and the
we ight of the object be ing transported.
When using a roof rack system which has a lower load ca rrying
capac ity, you must not use up the total maxim um permissible load
carrying capacity specified above . Instead, you shou ld load the roof
ra ck system only to the maximum capacity specified by the manufac­
turer of the roof rack system.
& WARNING
Weak, damaged or improper straps used to secure items to the
roof rack can fail during hard braking or in a collision and cause
seriou s personal injury.
• Make sure the roof rack is installed ex actly as specified above
~ page 93 .
• Always use suitable mounting straps for se curing items to the
roof rack to help prevent items from shifting or flying forward.
• Items on the roof rack must always be se curely mounted.
• The use of a roof rack can negatively affect the way a vehicle
handles . Ca rgo that is large , heavy, bulky , long o r flat will ha ve a
greater negative influence on the vehicle' s aerodyn amics, center
of gra vity and ove rall handling. Alw ays drive slowly, a void sudden
braking and maneuvers when tran sporting cargo on th e roof of
your veh icle.
& WARNING (contin u ed )
• Never e xceed the maximum permi ssible load carrying capacity
of the roof of your vehicle, the permi ssible a xle weights and the
permissible total weight of your vehicle~
page 3 5 7, "Weights".
• Alway s drive slowly, avoid sudd en braking and maneuv ers
when transporting cargo on the roof of your vehicle.
'£> For the sake of the environment
Sometimes it may be easier to leave a roof rack installed even tho ugh
you a re not using it. Due to the inc reased air resistance your veh icle
w ill unnecessarily use more fuel. Remove the roof rack if you are not
going to use i t. •

Using climate controls economically
Using the climate controls prudently can help save fuel.
When you use the a ir conditioner, e ngine power is reduced
and fuel consumption increa ses. To save fu el, you should use
the air co nditioner o nly when necessary. Also please note the
following points :
If you want to save fuel , activate ECON .
If you are going to drive with the wi ndows open, use ECO N.
~ For the sake of the environment
By reducing t he amount of fuel you use, you also reduce the amou nt
of pollutants emitted into the air .•

(I] Tips
• If a crack forms in the windshie ld due to a foreign object (e.g. a
stone chip), the defogger/defroster is not turned on. This prevents
the crack from spreading.
• We recommend that you locate an Audi dealership immediately to
have the windshie ld replaced. •
