Trail er to wing
Trailer towing
Driving with a trailer
General information
Your veh icle is primari ly intended for transport­
ing peop le and luggage. Howeve r, if you dr ive
with a tra iler , follow the techn ica l requirements ,
the operation and driving tips, and the lega l reg ­
ulations.
Dr iving w ith a trailer affects the vehicle 's fuel
consumpt ion, performance and wear. It a lso re­
quires higher concentration from the driver .
A WARNING
Do not transport any people in a trailer due to
the risk of fatal injury .
Technical requirements
Certain requirements must be met when towing
a trailer.
Trailer hitch
Only use a trailer hitch with a removab le ball
h itch mount and ball h itch. The tra ile r hitc h must
be pe rm it t ed for the vehicle, the tra iler and the
permitted tota l weight of the trailer being
pu lled . Above all, it must be secure ly and safe ly
attached to the vehicle trailer.
Never mo unt a t rai ler hitch on the bumper. The
trai ler hitc h must be mounted in a way that does
not impair the function of the bumper. Do not
make any changes to the exhaust system and the
brake system.
Check regu larly if the trai ler hitc h is securely
mounted . A lways follow the instructions given by
the trai ler hitch manufacturer .
Trailer brakes
If t he tra ile r has its own bra ke system, then fol­
low the manufacturer specifica tions. Howeve r,
the brake system on the trai ler must never be
connected to the vehicle brake system.
92
Engine cooling system
D riving w ith a tra ile r means a higher load on t he
engine and the cooling sys tem. The coo ling sys­
tem must be designed for additiona l load and
contain enoug h coo lant ~@ .
A WARNING -
- Never mount a "weight -distributing" or
"load-balancing" trailer coupler as the trail­
er hitch. The ve hicle was not des igned for
these types of tra iler h itches. The tra iler
h itch can malfunction and t he tra ile r can
b reak off from the vehicle.
- If t he tra ile r i s equ ipped w ith elect ronic
brakes, these brakes can not be activated by
a facto ry-installed control system, whi ch in­
creases the r isk of an accide nt.
- To red uce the r is k of injury, always remove
the ball hitch mount if no tra ile r is mo unt ­
ed.
@ Note
L onge r incl ines cannot be dr iven without a
su itab le cooli ng system, especially if the out­
s ide temperatu res a re high. ot herwise, this
i nc reases the risk of eng ine da mage.
Operating instructions
Several things must be noted when towing a
trailer.
Towing capacity
The permitted towing capacity must not be ex ­
ceeded under any circumstances~
page 376.
You can dr ive up larger inclines if you are not us­
i ng the maximum towing capacity.
The towing capacities given only apply to e leva ­
tions up to 3,200 ft (1,000 m) above sea level. As
the e levation increases, the engine power de­
creases due to the decreasing air pressures. T his
reduces the hill climb ing ability and towing ca­
pac ity . For every additional 3,200
ft (1,000 m),
t h e maximum permitted tow ing weight must be
r educed by app roximately 10% . T he pe rm itted
tow ing weight is t he comb ined we igh t of the
( loaded) vehicle and the (loaded) trailer .

::r ' -If you are unable to determine whether or
not a particular fue l blend meets the speci ­
ficat ions, ask your service station or its fuel
supplier.
- Do not use fuel for which the contents can ­
not be identified.
- Fuel system damage and performance prob ­
l ems resulting from the use of fue ls differ­
ent from those specif ied are not the respon­
s ibility of Audi and are not covered under
the New Veh icle or the Emiss ion Control
System Warrant ies .
- If you experience a loss of fue l economy or
driveability and performance problems due
to the use of one of these fuel blends, we
r ecommend that you switch to unblended
fuel.
Gasoline additives
A ma jor concern among many auto manufactur ­
ers is carbon deposit build-up caused by the type
of gasoline yo u use.
A lthough gasoline grades d iffer from one manu­
facturer to another, they have certain things in
common . A ll gasoline grades contain substances
that can cause deposits to collect on vita l engine
parts, such as fue l injectors and intake valves. A l­
though most gasoline brands include additives to keep engine and fuel systems clean, they are not
equally effective .
Audi recommends using TOP TIER Detergent Gas­
oline. For more informat ion on TOP TIER Deter­
gent Gasoline, please go to the official website
(www .toptiergas .com) .
After an extended period of using inadequate
fuels, carbon deposit build-ups can rob your en­
g ine of peak performance.
@ Note
Damage or malfunction due to poor fuel q ual­
ity is not covered by the Aud i New Vehicle
Limited Warranty.
Ch eck ing and F illing
Diesel fuel
App lies to : veh icles w it h diese l eng ine
Always use U LSD (Ult ra Low Sulfur Diesel) No. 2.
T he ULSD No. 2 meets the AS TM D975.
D iesel fuel w ith concentrations of b iod iesel h igh­
er than 5
% such as B 11, B20 or B100 are strict ly
proh ib ited.
Service station fuel pumps are labeled with the
correct fuel information for easy recogn it ion by
the user . If the d iesel fue l pump is not labeled
ask the station operator what fuel is being dis ­
pensed before fill ing up your vehicle.
U LSD No . 2 may not be ava ilable outside the USA
and Canada . Be su re to check befo re traveling to
othe r countr ies.
ULSD No . 2 can become thicker in very cold tem­
peratures, and th is can impa ir the engine's start­
i ng and runn ing . Depend ing on the season , gas
stations provide ULSD No. 2 that flows bette r in
co ld tempe ra tures so that you can co nti nu e ope r­
at ing you r vehicle as usual.

Checking and Filling
Refueling
Fueling procedure
Fig. 254 Right re ar side of the vehicle : opening the fue l
filler door
Fig. 255 Fu el fi lle r door w it h atta ched fuel cap
The fuel f ille r door is unlocked or locked by the
central locking system .
• Press on the left side of the fuel filler door to
open
c:!;> fig. 254.
• Unscrew the tank cap counterclockw ise.
• Place the cap from above on the open fue l filler
door c:!;>fig. 255.
• Insert the fu el pump no zz le all the way into th e
fuel filler neck.
• Begin fueling . Once the fuel pump noz zle turns
off the first time, the fuel tank is full. Do not continue fueling , or else the expans ion space in
the tank will be filled with fuel.
• After the fuel pump has switched off , wait five
seconds before remov ing it to allow the rest of
the fuel to f inish dripp ing into the fuel tank.
• Turn the fue l cap clockwise until you hear it
lock.
• Close the fuel filler door and then pr ess on th e
left side until it latches.
The correct fu el type for your vehicle can be

filler door. For additional information on fuel,
se e
c:!;> page 310.
For the tank capacity in your veh icle, refer to the
Technica l Data
c:!;> page 3 75 .
To reduce the risk of fuel leaking out or vapors
escaping, make sure that the fuel tank is closed
correctly. Otherw ise the
¢'4 ind icator light wi ll
turn on.
If the cent ral locking system malfunctions , the
fuel filler doo r may emergency re lease
c:!;> page 314.
& WARNING
An improper fueling procedure and improper
handling of fuel can lead to explosions, fires,
severe burns and other in juries.
- Do not smoke and keep away from open
flames.
- The ignition must be sw itched off when re­
fueling.
- Cell phones, radio devices and other rad io
equipment should a lways be switched off
when refueling. E lectromagnetic rays could
cause sparks and start a fire.
- If you do not insert the fuel pump nozzle all
the way into the filler tube, then fuel can
leak out. Spilled fuel can ignite and start a
fire .
- Never get into the vehicle when refueling . If
there is an exceptional situation where the
vehicle must be entered, close the door and
touch a metal surface before touching the
fuel pump nozzle again . This will reduce the
r isk of electrostatic discharge that can cause
f lying sparks. Sparks can start a fire when
refueling.
& WARNING
We recommend that you do not transpo rt any
f u el containers in the vehicle . Fuel could leak
out of the container and ignite, especially dur­
ing an accident. This can cause explosions,
fires and injuries.
- If you must transport fuel in a fuel contain­ er, p lease note the following :
