" N .... 0 0 <..:l ' Trailer towing 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 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.
(D Note
If you are going to tow a trailer, you must ac­
tivate the trai ler operation mode
c::> page 83, Operating instructions.
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
c::> .&, .
Tra iler towing
Trailer brakes
If your trailer is equipped with a braking system,
check to be sure that it conforms to all regu la­
tions.
T he trailer hydraulic brake system must not be
directly connected to the vehicle's hydraulic
brake system.
Safety chains
Always use safety chains between your vehicle
and the tra iler .
Trailer lights
Trailer lights must meet all regulations. Be sure
to check with your Audi dealer for correct wiring,
switches and relays.
Mirrors
If you are unable to see the traffic behind you us­
ing the regular outside mirrors, then you
must in­
stall extended mirrors . It is important that you
always have clear vision to the rear .
A WARNING
--
After removing the trailer hitch, do not store
it in your vehicle. In case of sudden braking,
the hitch could fly forward and injure you or
your passengers.
Operating instructions
Maximum trailer weight
A trailer for your vehicle is lim ited to a typical
class 1 or class 2 trailer.
Trailer load distribution
Be sure the load in the trailer is held securely in
place to prevent it from shifting forward, back­
ward or s ideways.
Never allow a passenger to ride in a trailer c::> .&.
in Driving instructions on page 85 .
Engine cooling system
Towing a trailer makes the engine work harder. It
is important that the cooling system's perform­
ance is up to the additional load. Make sure that
the cooling system has enough fluid . ..,.

Intelligent Technology
Braking
New brake p ads
New b rake pads do no t achieve the ir full b raking
effect during the firs t 250 mi (400 km) . They
m ust be "broken in" first .
Wear
Brake pad wear depends largely o n the way the
ve hicl e is driven and on operat ing cond it ions.
This is especi ally true if you are d riving frequently
in the c ity and on c urves or with a sporty driving
style.
Operating noise
Noises may occur when bra king depend ing on the
speed, b raking force and outs ide cond it ions s uch
as temperature and humidity.
Effect of water and road salt
In ce rtain s ituations, for example after driving
through water, in heavy ra in, afte r ove rnight con­
densat ion or after washing your car, the b raking
effect can be red uce d by mo isture or ice on the
b rake rotors and brake pads. The brakes must be
"dried" first with a few careful brake applica­
tions.
At highe r speeds and with t he windshie ld wipers
turned on, the brake pads press against the bra ke
rotors for a short amount of time . This action,
which is not felt by the driver, happens at regular
intervals and ens ures a better reaction time for
the brakes in wet weathe r.
The braking effect can also be reduced if you are
driving on sa lted roads and you do not apply t he
brakes for long periods of time. The layer of salt
on the brake rotors and pads must be worn off
first when the brakes are applied.
Corrosi on
Leaving the vehicle parked for long periods of
time, low mi leage and avo iding heavy brak ing
can contribute to corrosion on the brake rotors
and to d irty brake pads.
If you usually avoid heavy b raking or if there is
corros ion present, occasional heavy braking at
122
high speeds is recommended to clean the brake
rotors and pads¢.&. .
Brake system malfunction
if you not ice that the b rake peda l t ravel has sud­
denly increased, then a br ake circuit in the du al­
c irc uit b rake system may have malfunctioned.
Drive to an authorized A udi dealer or authorized
A udi Se rvice Facility immediate ly to have the
problem corrected. On the way there, drive w ith
reduced speed and keep in m ind t hat you will
need a longer distance to stop and you will need
to press the brake peda l harder .
lo w b rake fluid level
When the brake fluid level is low, malfunctions in
the brake system may occur. The brake fluid level
i s electronically monitored.
Brake booster
The brake boos ter amp lifies the pressure you ap ­
ply to the brake pedal. It only works when the en­
gine is running .
A WARNING
- Only app ly the brakes for the purpose o f
cleaning the brake system when road and
traffic conditions permit. You must not en­
danger other road users. This i ncreases the
r is k of an accident .
-
- Never let the ve hicle roll while the engine is
s topped because this i ncreases the ris k of an
accident .
- New brake pads do no t ach ieve the ir full
braking effect dur ing the first 250 m i
( 4 00 km). They m ust be "b roken in" fi rst.
However, you can compensa te fo r the
slightly reduced brak ing force by pressing
firm ly on the brake pedal. Avo id heavy brak ­
ing during the break-in period.
- Ce rtain weather and operating condi tions
such as d riving through water, dr iv ing in
heavy rain o r driv ing after washi ng your ve­
hicle can impai r the effectiveness of the
brakes. In the winter, ice may build up on
the brake pads, rotors and dr ums. Check

co
co
.... N
" N .... 0 0 <..:l ' -Do not remove the engine cover under any
circumstances . This increases the risk of
burns.
- If tests need to be performed with the en­
gine running, there is additional danger due
to moving components (such as the ribbed belt, alternator and radiator fan) and from
the high voltage ignition system.
- Do not under any circumstances give gas in­
advertently (for example, by hand from the
engine compartment) if the vehicle is sta­
tionary but the engine is running and a gear
is engaged. Otherwise, the vehicle will start
to move immediately and this could result
in an accident.
- Pay attention to the following warnings list­
ed when work on the fuel system or on the
electrical equipment is required.
- Do not smoke .
- Never work near open flames.
- Always have a working fire extinguisher
nearby
- All work on the battery or electrical system
in your vehicle can result in injuries, chemi•
cal burns, accidents or burns. Because of
this, all work must be performed
only by an
authorized Audi dealer or authorized Audi
Service Facility.
- To reduce the risk of electric shock and in­
jury, never touch the following components when the engine is running or is being start­
ed :
- Ignition cable
- Other components in the electronic high-
voltage ignition system
- If you must check or perform work on the
engine while it is running:
- Set the parking brake and place the selec­
tor lever in the P (park) position first .
- Always proceed with extreme caution so
that clothing, jewelry or long hair do not
become caught in the radiator fan, fan
belt or other moving components or do not come into contact with hot compo­
nents. Tie back long hair before beginning
work and do not wear clothing that can
hang down into the engine .
Checking and Filling
-Limit your exposure to exhaust and chemi­
cals to as short a time as possible
c:> A .
