General information
Your Audi was designed primarily for passenger
transportation .
If you plan to tow a trailer, please remember that
the additional load will affect durability, econo­
my and performance.
Trailer towing not only places more stress on the
vehicle, it also calls for more concentration from
the driver.
For this reason, always follow the operating and
driving instructions provided and use common
sense.

Technical requirements
Trailer hitch
Use a weight-carrying hitch conforming to the
gross trailer weight. The hitch must be suitable
for your vehicle and trailer and must be mounted
securely on the vehicle's chassis at a
technically
sound
location . Use only a trailer hitch with a re­
movable ball mount. Always check with the trail­
er hitch manufacturer to make sure that you are
using the correct hitch.
Do not use a bumper hitch.
The hitch must be installed in such a way that it
does not interfere with the impact -absorbing
bumper system . No modifications should be
made to the vehicle exhaust and brake systems .
From time to time, check that all hitch mounting
bolts remain securely fastened.
When you are not towing a trailer,
remove the
trailer hitch ball mount . This prevents the hitch
from causing damage shou ld your vehicle be
struck from behind

Trailer lights
Trailer lights must meet all regulations. Be sure
to check with your Audi dealer for correct wiring,
switches and relays.
