-Objects fall ing from t he roof of a vehicle can
cause a crash and personal injury.
- Only mount the roof rack on the designated
locations on the roof
c> fig. 66.
- The roof rack system must be insta lled ex­
act ly according to the instructions provided .
- When driving with a roof rack system,
changes to the center of g ravity and wind re­
sistance can change the vehicle handling
and lead to a collision. A lways adapt your
dr iv ing and your speed to the current condi­
t ions .
- Your vehicle warranty does not cover any
damages to the vehicle caused by using roof
racks or mounting structures not approved
by Aud i for your vehicle. The same applies to
damage resulting from incor rect roof rack
i nsta llation.
- Always check the roof rack mount ings and
hardware before each t rip and dur ing a tr ip

ened.
If necessary, re tighten the mo untings
and c he ck the en tire system from time to
time.
- After mounting a roo f rac k system, o r when
you transport objec ts on the roof of your ve­
hicle, the heig ht of the vehicle is nat urally
increased. Be caref ul when driving under
l ow bridges or in parking garages for exam­
ple. This cou ld cause damage to the load
and even t he vehicle itself.
- Make sure that the open rear lid and the
sunroof do not come into contact w ith ob­
jects on the roof.
Loading the roof rack

~ Always dist ribute the loads on the roof rack
evenly.
~ Always attach items to the roof rack securely
before you drive

Seat s and stor age
weight of the roof rack, the attachments and the
cargo you are carrying . You must a lso not exceed
the max imum load weight for the roof rack you
are using.
When using a roof rack system which has a lower
load carrying capacity, you must not use up the
total max imum permissib le load carrying capaci­
ty specified above. Instead, you should load the
roof rack system only to the maximum capacity
specified by the manufacturer of the roof rack
system .
A WARNING
