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 .

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
found on a lab el located on the inside of the fue l
312
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 :

A WARNING
The temperature of the exhaust system is
high, both whe n driving and after stopping
the engine .
- Never touch the exhaust ta il pipes once they
have become hot. This could result in burns .
- Do not park you r vehicle over flammable
materials such as g rass or leaves because

Observe the safety precautions¢ A in Working
in the engine compartment on page 319.
~ Park your vehicle on a level surface.
~ Shut the engine off when it is warm.
~ Switch only the ignition back on.
~ Wait approx imately two minutes.
~ Select in the Infota inment system: the I MENU I
button > Ve hicle > left contro l button > Ser vic e
& chec ks > Oil level.
~ Read the oi l level in the display . Add engi ne oil
if th e ba r in the oil leve l ind icator is j ust before
"min" ¢
page 323.
{U) Note
The engine o il leve l must not be unde r the
"min" marking, as this will increase the risk of
engine damage .
(D Tips
The oil level indicato r in the display is on ly an
informationa l display . If the o il level is too
low, a minimum oi l warning appears in the in ·
strument cluster. Add oi l and close the hood.
The current oil leve l is d isplayed in the Info­
tainment system the next time the ignition is
sw itched on.
(D Tips
The engine oil consumption may be up to
0.5 quart/600 m iles (0.5 liter/1,000 km), de­
pending on driving style and operating condi­
tions. Consumpt ion may be h igher during the
first 3,000 miles (5,000 km). Because of this, the engi ne oil level m ust be chec ked regular·
Ly. It is best to c hec k each t ime yo u refuel
your veh icle and before long dr ives.
322
- In order to prov ide e ffective lubrication and
cooling of interna l engine components, a ll
internal comb ustion engines consume acer ­
tain amount of oil. Oil consumption var ies
from engine to eng ine and may change sig­
nificantly over the life of the engine. Typi·
cally, eng ines with a specified break-in per i·
od consume mo re o il during the break-in pe·
r iod than they consume afte r oil cons ump·
t ion has s tabilized.
- Under no rma l co nd it ions, the rate of oil
c ons umption depends on the q ual ity and
vis cos ity of the oil, the RPM (revo lutions per
min ute) a t which the engine is operated, the
ambient temperature and road conditions .
Further factors are the amount of oi l di lu ­
t ion from water condensation or fuel resi­
due and the oxidation level of the oil. As any
eng ine is subject to wear as m ileage bu ilds
up, the oil consumption may increase over
t ime until replacement of worn components
may become necessa ry.
- With all these var iables comi ng into play,
no standard rate of o il consumption can be
established o r spe cified. There is no alter na­
t ive to c hec king the oil leve l reg ularly and
frequently.
- If you have the impress io n your e ng ine co n­
s u mes excessive amou nts of oi l, we recom ­
mend that yo u consult an authorized A udi
dea ler to have the cause of your concern
properly diagnosed . Keep in mind that the
acc urate measurement of o il cons umption
requires great care and may take some
t ime. An authorized Aud i dealer has instruc­
t ions about how to measure o il consump·
t ion accurate ly.
