Roof carrierApplies to vehicles: with roof carrier: Under development at the time of printDescription
Additional loads can be transported using the roof carrier.Note the following points if you in tend to carry loads on the roof:•
The rain channels are moulded into the roof as part of the aero-
dynamic roof design. It is therefore not possible to mount conven-
tional roof luggage racks. We recommend using the carrier units
from the range of Audi Genuine accessories.
•
These carrier units form the basic elements of a complete roof
carrier system. Special fixtures must then be added in order to
safely transport luggage, bicycles, sk is, surf boards or boats on the
roof. All the elements of this syst em are available from Audi dealers.Caution
Any damage to the vehicle caused by the use of other types of roof
rack or incorrect installation will not be covered by the factory
warranty. The roof carrier system mu st therefore be installed exactly
according to the instructions provided.

84Attachment points
The roof carrier must be attached at the marked points
only.Mounting
The feet of the roof carrier must always be attached at the position
where the holes in the roof frame are located ⇒fig. 92. The holes
are only visible when the doors are open. When using roof carriers
with pins, make sure that the pins are securely fixed in the holes
when mounting the carrier units.
WARNING
After driving a few kilometres, check that the roof carrier is
securely attached.
Note
Each roof carrier has a marking to indicate whether it is to be fitted
at the front or rear of the vehicle.
Roof loadLoads carried on the roof must be securely attached. The
car's handling is affected when transporting loads.The maximum permissible roof load for your vehicle is 90 kg. The
load limit applies to the combined weight of the carrier system and
the load itself.
It will not be possible to carry the full maximum load if the roof
carrier you are using is rated for a load which is less than this figure.
Do not exceed the maximum weight limit for the roof carrier, which
is listed in the fitting instructions.
WARNING
•
To prevent accidents, loads ca rried on the roof must be
securely attached.
•
Do not exceed the maximum roof load for the vehicle, the
maximum axle loads or the maximu m gross vehicle weight, as this
could cause an accident.
•
When transporting heavy or bulky loads on the roof, bear in
mind that the car's handling is affected by the extra weight on the
roof and a possible susceptibility to cross winds. Adjust your
speed and driving style acco rdingly to avoid accidents.For the sake of the environment
The increased air resistance when the roof carrier is fitted means
that the vehicle uses more fuel. Fo r this reason you should always
take off the roof carrier when it is not in use.
