2 Safety notes
2.1 General safety notes
WARNING
Please read these assembly instructions carefully before starting installation. Non-compliance
with these installation instructions and safety notes will compromise your safety and that of third
parties.
WARNING
All bolted connections and connections for the carrier units and for the roof rack modules must
be checked prior to travelling to make sure that they are correctly positioned and installed. Tight-
en if necessary.
Recheck bolted connections and connections at appropriate intervals and tighten if necessary.
The bolted connections and connections must be checked at short intervals if travelling on a
poor stretch of road.
If these guidelines are not observed, this can result in the carrier units or the roof rack modules
becoming loose or falling off – risk of accident!
WARNING
The procedures and safety notes detailed in these instructions for the installation, handling and
use of the carrier units must always be observed.
◆Deviating from these instructions can cause the carrier units or the mounted roof rack module
to come loose.
◆The carrier units are designed such that the vehicle will not be damaged if components are in-
stalled, handled and used properly.
◆The manufacturer is not liable for any damage resulting from failure to comply with the installa-
tion procedure or notes specified.
◆All forms of warranty claim against the manufacturer are invalidated if installation, handling or
use of the components is not carried out as specified in these instructions.
WARNING
Repairs or the replacement of parts must only be performed by a qualified workshop. It is recom-
mended that genuine spare parts available from your Audi partner are used.
WARNING
The driver is responsible for making sure that his view and ability to hear are not impaired by his
load or by the condition of the vehicle.
He must make sure that the load does not prevent the vehicle from complying with country-spe-
cific regulations and that road safety is not compromised.

22 Safety notes

Note
◆When driving with a roof load, make sure that the German Road Traffic Regulations (StVZO) or any coun-
try-specific regulations are observed.
◆For reasons of convenience, it is common for the carrier units with/without roof rack modules to remain on
the vehicle, even if they are not in use. Your vehicle will consume more fuel due to increased wind resist-
ance.
◆We therefore recommend that you remove the carrier units after use.
◆Increased wind noise can result from driving with the roof bars attached.
◆Do not use elasticated straps or bungee cords!
◆Replace damaged components immediately.
2.2 Safety notes to be checked before and after each journey and when in
use
WARNING
Check that the carrier units and the load to be transported are securely attached:
◆Before the start of every journey,
◆After approx. 10 km of the journey,
◆approx. every 300 km on good roads
◆Frequently on poor roads (due to vibration),
◆Regularly to make sure that there has been no movement/displacement.
If the carrier units are not checked to make sure that they are secure and to check whether any
fasteners need tightening, they could work loose and parts may therefore be lost, despite instal-
lation being carried out properly – risk of accident!
In the event of a change in position, drive at a reduced speed until the next opportunity to stop
safely and then re-tighten the bolted connections and fixtures on the carrier units.
2.3 Safety instructions for driving with carrier units
2.3.1 Altered vehicle height
Caution
Fitting carrier units changes the height of your vehicle.
Pay particular attention to:
◆Low-hanging branches
◆Passages with reduced head-room clearance
◆Entrances to garages with reduced head-room clearance
◆Height restrictions in multi-storey car parks and underground car parks.
Caution
Do not enter a car wash with carrier units with/without roof rack modules installed.
