Driving
with
a trailer
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

not

vehicle, it also calls
for
more concentration
from
the driver.
For
this reason, always follow the operating and
driving

use
common

Technical requirements

gross trailer weight.
The

in
such a way that it
does not interfere with the impact -absorbing
