A WARNING
To reduce the risk of poisoning, never allow
the engine to run in confined spaces .
-

Outside mirrors
If yo u cannot see the traffic behind the tra iler
with the standard exterior mirrors, then you
must attach additiona l exterior mirrors . Adj ust
them so you have a sufficient visibility behind
you .
Exterior lighting
Follow the legal regulat ions regard ing the light­
ing equipment on your trailer . Contact an author ­
ized Audi dealer or authorized Audi Service Facili­
ty for more information.
Before starting to drive, check all lighti ng equip­
ment on the hitched trailer.
The headlight range contro l adjusts automatical­
l y to the light range of the headl ights.
Safety chains
Make sure the safety chains are correctly applied
when pull ing a trailer . The chains should hang
enough so that the trailer can dr ive around
curves. However, they must not touch the
g ro und .
(D Tips
-Use chocks whe n parking on incl ines if the
trailer is load ed.
- We recommend also hav ing the veh icle in­
spected between the inspect ion intervals if
you are towing a trailer frequently.
- Avo id driving with a trailer during the vehi­
cle break- in period .
Driving with a trailer
Driving with a trailer requires extra caution.
Speed
Adhere to the legal speed limits. Follow the legal
regulations specific to the country.
As the speed increases, the driving stability of
the trai ler decreases. Therefore you should not
exceed the maximum legal speed limit when
u. there are unfavorable road, weather and/or wind 00
~ conditions . This especially applies when driving
~ downhill.
0 N > 00
Trailer towing
You m ust always reduce your speed as soon as
you notice even the slightest swinging motion of
the tra iler. Never try to "stra ighten out" the tra il­
er by acce lerating.
T he weight distribution is very poor if the vehicle
is empty and the trai ler is loaded . However if you
must drive under these circumstances, then dr ive
especially slowly .
Brakes
Brake in a timely manner. Downshift before driv ­
ing down hill so that t he engine can assist with
braking ~.&. .
When using a trailer w it h overrun brakes, first
brake gently then quickly. This reduces the r isk of
jerking while braking if the trailer wheels lock up .
Engine coolant temperature
Pay attention specifically to the coo lant tempera­
ture display when there are high outside temper­
a tur es, and when driving on long inclines
~page 11. Shift to a hig her gear in a timely man­
ner .
A WARNING
= -
Constant braking causes the brakes to over-
heat and substantially reduces braking per­
formance, increases braking distance or caus­
es complete failure of the brake system.

sound as an addit ional indicator when dr iving in
reverse.
- Automat ic brake acti vation : a brief activation
of the brakes may also warn you of a potent ial
collision w ith an approaching object.
The audib le warning signal and the automatic
bra ke activation occur only when driv ing in re ­
verse.
A WARNING

rect t ime.
- Please note that the rear cross-traff ic assist
may activate the b rakes unexpe cted ly. Se­
cure a ny cargo th at you are transpor ting to
redu ce t he risk of damage or i njury.

ge red w ith in 10 seconds after an automatic
b rake activation.
- I f the re is an acoustic wa rn ing s ignal from
the rea r cross-traffic ass ist, t hen the p ark­
ing sys tem may not warn you of detected
obstacles under certain circumstances.
- The v iew o f the radar sensors may be im­
pa ired by leaves, s now, heavy sp ray or dirt.
Clean the area i n front of the sensors

A WARNING
-
-The rear cross -traffic assist will not provide
alerts if your vehicle is pulled too far into
the parking space so that it is hidden by ad­
jacent vehicles.
- The rear cross-traffic assist will not provide
alerts about people a nd can not warn you
about every type of approaching objects,
such as cyclists. Always monitor the t raff ic
