Trailer towing Driving with a trailer
General information
Your Audi was designed primarily for passen­
ger transportation .
If you plan to tow a trailer, please remember
that the additional load will affect durability,
economy and performance .
Trailer towing not only places more stress on
the vehicle, it also calls for more concentra­
tion 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
activate the trailer operation mode
q page 159, Towing a trailer.
Technical requirements
Trailer hitch
Use a weight-carrying hitch conforming to the
gross trailer weight. The hitch must be suita­ ble 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 removable ball mount. Always
check with the trailer 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-absorb­
ing bumper system. No modifications should
be made to the vehicle exhaust and brake sys­
tems . 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 should your vehi­
cle be struck from behind~.&.
Trailer towing 241
Trailer brakes
If your trailer is equipped with a braking sys­
tem, check to be sure that it conforms to all
regulations.
The trailer hydraulic brake system must not be
directly connected to the vehicle's hydraulic
brake system
q .& .
Safety chains
Always use safety chains between your vehicle
and the trailer.
Trailer lights
Trailer lights must meet all regulations. Be
sure to check with your authorized Audi dealer
for correct wiring, switches, and relays.
Mirrors
If you are unable to see the traffic behind you
using the regular outside mirrors, then you
must install extended mirrors.
It is important
that you always have clear vision to the rear.
_&. WARNING
-If a trailer has electrical brakes please
note that these brakes are not activated
by the factory-fitted control unit -risk of
accident!
- 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.
- Never install a "weight distributing" or
"load equalizing" trailer hitch on your ve­
hicle. The vehicle was not designed for
these kinds of trailer hitches. The hitch
attachment can fail, causing the trailer
to tear loose from the vehicle.
- The Gross Vehicle Weight Rating for your
vehicle, found on the safety compliance
label on the driver's side B-pillar, must
never be exceeded under any circumstan­
ces. Exceeding the Gross Vehicle Weight
Rating of your vehicle is likely to damage
your vehicle, and such damage will not
be covered by your Limited New Vehicle
-
Warranty. Exceeding the Gross Vehicle ~

242 Trailer towing
Weight Rating will also change the per­
formance and handling characterist ics of
your vehicle, which could cause a crash result ing in serious injury or death .
- The Gross Vehicle Weight Rat ing for your
vehicle would be exceeded if your vehicle
is simultaneously equipped with Panor ­
am ic sliding sunroof; th ird-row seating;
t railer towing equipment (factory or
dealer-installed) , and running boards
(deale r-installed) . UNDER NO CIRCUM ­
STANCES MAY ALL SUCH ITEMS BE IN­
STALLED ON THE SAME VEHICLE.

Trailer towing weights
With a factory-installed trailer hitch, the
maximum permissible trailer weight is 6,615
l bs (3,000 kg) . Th e maximum permissible un­
braked trailer weight is 1,650 lbs (750 kg).
With an
aftermarket trailer hitch, the maxi­
m um permissible trailer weight is 5,512 lbs
(2,500 kg) . These specifications apply when
driving on roads having an incline of less than
12%.
Permissible tongue load
F or best vehicle handling under these
changed condit ions, adjust the trailer load so
that the tongue load is at the maximum al­
lowable or slightly lower . You can get an ap ­
prox imation of the tongue load w ith a bath­
room scale or you can measure the load at a
trucking company or weighing station .
With a
factory-installed trailer hitch, the
maximum permissible load on the ball h itch may not exceed 662 lbs
(300 kg). With an
af­
termarket
trailer hitch, the maximum permis­
s ib le load on the ba ll hitch may not exceed
551 lbs (250 kg). It is recommended to use
the maximum permissible load.
Trailer load distribution
Be sure the load in the trailer is held secure ly
in place to prevent it from shifting forward,
backward or sideways.
Never allow a passenger to ride in a trailer
¢&. in Driving instructions on page 243.
Ball mount
The trailer hitch may only be used w ith suita­
ble ball mount and ball¢
fig. 233. In stalla­
tion of the hitch ball must be carried out in ac­
cordance with the manufac turer's instruc­
tions. At the height dimension of 1.5 in
(38.5 mm) a tolerance of +/- 0.5 in (12. 7 mm)
is permissib le.
Engine cooling system
Towing a trailer makes the engine work ha rd­
er . It is important that the cooling system's
performance is up to the additional load .
Make sure that the cooling system has enough
fluid .
Tire pressure
When towing a trailer, infla te the tires of your
vehicle to the cold tire pressu re listed under
" Full l oad" on the tire pressure label. The tire
pressure label is located on the driver's side B­
pillar . Inflate trailer tires to trailer and tire
manufacturers' spec ificat ions .
Lights
The headlight settings shou ld be checked with
the trai ler attached before driving
off. Check
to make sure both vehicle and trailer lights
are working properly.
Safety chains
Be sure trailer safety chains are properly con­
nected from the trai ler to the h itch on the ve ­
hicle. Leave enough slack in the chains to per­
mit turning corners. When you install safety
IJ,,

directly at locks, or at door or hatch
openings -they can freeze shut.
- Never use sponges designed to remove
insects , or any kitchen scouring sponges
or similar products. They can damage
your paint finish .
- You should remove debris (such as in­
sects) from the headlight lenses on a
regular basis, for example when refuel­
ing your vehicle. Never use a dry cloth or
sponge to clean the headlights . Only use
wet cloths or sponges to prevent
scratches . It is best to use soapy water .
@) For the sake of the environment
In the interest of the environment, the ve­
hicle should only be washed in special
wash bays .
Washing your vehicle with a power
washer
Cleaning the exterior of your car with a high­
pressure power washer is safe as long as you observ e a few simple rules.
" Before using the power washer , make sure
you have read and understood the WARN­
INGS ~.&.
in General information on
page 245.
" Always follow the operating instructions for
the pow er wash er.
" Make su re that the jet on the spray hose
produces a "fan shaped spr ay" .
" Do
not hold the spray nozzle too close to
soft materials .
When cleaning the vehicle with a power wash­
er
always follow the operating ins truc tions.
T his applies particularly to the
operating
pressure
and the spraying distance. Maintain
a sufficient distance to soft materials such as
rubber hoses and sound/vibration deadening
materials (particularly on the underside of the
engine hood). Do not use a jet which sprays
water in a
direct stream or one that has a ro­
tating
jet.
Water temperature should not exceed 140 °F
(60 °().
Cleaning and protection 247
A WARNING
Never wash tires with a jet that sprays wa­
ter in a direct stream . This could cause in­
visible damage to the tires and weaken
them, even if the spray is from a relatively
long distance and for a short time . Dam­
aged and weakened tires can fail and cause
accidents and personal injury.
(D Note
To avoid damaging your vehicle, always make sure that there is sufficient distance
between the spray head and soft materials
like rubber hoses, plastic parts and sound­
deadening materials. Never aim the spray
head at the same point for a long time.
This also applies to cleaning headlights
and painted bumpers. Remember : the
closer the nozzle is to the surface of the
material, the greater the stress on the ma­
terial.
Sensors and camera lenses
- Remove snow with a hand brush and remove
ice with a de-icing spray that does not con­
tain solvents.
- Clean the sensors (adaptive cruise control*,
parking system*) with a cleaning solution
that does not contain solvents and a soft
cloth.
- Dampen the camera lens with a household
alcohol-based glass cleaner, and then wipe
the lens clean with a dry cloth.
(D Note
- If you wash your vehicle with a pressure
washer,
- make sure there is enough distance to
sensors in the rear bumper .
- do not clean the camera lenses and the
area around them with the pressure
washer .
- Never use warm or hot water to remove
snow or ice from the camera lens. This
could cause the lens to crack .

should only be disconnected from the vehicle
e lectrical system when absolutely necessary
for repairs.
Vehicles not driven for long periods
If you do not drive your vehicle over a pe riod
of several days or weeks, electrical compo­
nents are gradually cut back or switched off.
This reduces energy consumption and main ­
tains starting capab ility over a longer period
<=> page 231.
Take into consideration that when you un lock
your vehicle, some convenience functions, such as the interior lights or the power seat
adjustment, may not be available. The con­
venience functions will be available again
when you turn on the ignition and start the
engine .
Winter operation
During the winter months, battery capacity
tends to decrease as temperatures drop . This
is because more power is also consumed while
starting, and the headlights, rear window de ­
fogger, etc., are used more often .
Avoid unnecessary power consumption, par­
ticularly in city traffic or when traveling only
short d istances . Let your authorized Audi
dealer check the capacity of the vehicle bat­
tery before w inte r sets in
<=> page 277. A well
cha rged battery w ill not only prevent starting
p rob lems when the weather is cold, but will
a lso last longer.
(D Tips
If your vehicle is left standing for several
weeks at extremely low temperatures, the
vehicle battery should be removed and
stored where it will not freeze . This wi ll
prevent it from being damaged and having
to be replaced.
