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.
118
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
coolant ¢@ .
@ Note
Longer incl ines cannot be driven wi tho ut a
suitab le cooling system, especia lly if the out ­
side temperatures are high . ot herwise, this
i ncreases the risk of eng ine damage.
Operating instructions
Several things must be noted when towing a
trailer.
Towing capacity
Yo ur vehicle can only be ope ra ted with class 1 or
class 2 trai le rs.
Load distribution
Poor cargo load and distr ib ution can negatively
i mpact vehicle handling . T o have the lowest im­
pact as poss ible, load the tra ile r according to
t h ese cr ite ria :
- Store objects preferably in the vehicle luggage
compartment . The vehicle should a lways carry
the heaviest poss ib le load and the trailer
should have t he lig htest poss ible load .
- Dist ribute the load in the t railer so that the
heavy objects a re as close to the axle as poss i­
ble.
- Secu re objects from s lid ing o ut of place.
- Ut il ize the maximum permitted tongue we ight
if poss ible .
Tire s
Set the tire pressure on your vehicle for a "full
load"; see the tire pressure
st icker ¢ page 341.
If necessary, also adjust the t ire pressure on the
trailer acco rding to the manufactu rer's recom­
mendat ion.
Winter tires should be mounted on the vehicle and on the trailer during w inter temperatures .

Checking and Filling
If the recommended engine oil is not available,
in an eme rg enc y you may add a maximum of 1
quart(! liter) of ACEA C3 or API SN engine oil
one tim e until the next oil change.
F or more information on the correct engine oil
for your vehicle, contact an authorized Audi dea l­
er or authorized Audi Service Facility . Have the oil
changed by an authori zed Audi dealer o r author­
ized Service Fac ility .

Checking the engine oil level
The engine oil dipstick varies depending on the
engine type .
Fig . 268 Oil d ipsti ck: checking th e engine oil le vel (exa m­
p le )
Observe the safety precaut ions ¢.& in Working
in the engine compartment on page 318 .
.. Park your vehicle on a level surface.
.. Shut the engine off when it is warm .
.. Wait approx imately two m inutes .
.. Open the hood ¢ page 320 .
.. Remove the oi l dipstick¢ page 321, fig. 267,
wipe it off with a clean cloth and insert it a ll the
way in again .
.. Remove the o il dipstick again and then read the
oil
level ¢ table on page 322.
.. Add engine oil if necessary c:> page 323.
322
Areas on the o il dipstick 9 fig . 268 .
(D If the engine oil leve l is just before the
mark ing
(D , then engine oil must be added .
See¢@.
@ Do not add engine oil.
(D Note
- T he engine o il level must not be below the
ma rking
(D , because this increases the risk
of engine damage.
- After add ing engine oil, the oil leve l must
not be above the marking @, because this
increases the risk of catalytic converter and/
or engine damage . Do not start the engine .
Contact an authorized Audi dealer or au­
thorized Audi Service Facility to have excess eng ine oil extracted if necessary .
(D Tips
- The engine oil consumption may be up to
0.5 quart/600 miles (0.5 liter/1,000 km),
depending on driving style and operating
conditions. Consumpt io n may be h igher
dur ing the fi rst 3,000 mi les (5,000 km) . Be­
c ause of this , the eng ine o il level must be
che cked regularly.
It is best to check each
t ime you refuel your vehicle and before long
drives .
- In order to prov ide effective l ubrication and
cooling of interna l engine components, a ll
internal combustion engines consume a cer ­
tain amount of oil. O il consumption varies
from engine to engine and may change sig­ nificantly over the life of the engine. Typi­
cally, eng ines with a specif ied break-in peri­
od consume more oil during the break-in pe ­
riod than they consume after o il consump­
t ion has stabilized .
- Under normal condit ions, the rate of oil
cons umption depends on t he quality and
viscosity of the oil, the RPM (revo lutions per
mi nute) at which the engine is ope rated, the
ambien t temperature and road conditions .
Further factors are the amount of oi l dilu­
tion 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 builds

Check ing and F illing
Changing the engine oil
We recommend that have your oil changed by an
authorized Audi dealer or a qualified service sta­ tion.
Before you check anyth ing in the eng ine compart­
ment,
a lw ays re ad and h eed all WARNING S c> .&
in Working in the engine compartment on
page 318.
The engine oil must be changed accord ing to the
intervals specif ied in your Warranty
& Mainte­
nance booklet. This is very impo rtant because the
lubricat ing p ropert ies of o il d iminish gradually
du ring normal vehicle use.
Under some c ircumstances the eng ine o il should
be changed more frequently . Change oil more of­
ten if you d rive most ly short distances, ope rate
the vehicle in dusty areas or under predominant ly
stop -and-go traffic cond it ions, o r have yo ur vehi ­
cle where temperatures remain below freezing
for extended periods .
Detergent additives in the oil will make fresh o il
look da rk afte r th e e ng ine
has been run ning fo r a
short time. This is norma l and is not a reason to
change the oil more often than recommended.
Because of the prob lem of p roper d isposa l, along
with the special tools and necessa ry expe rt ise re ­
quired, we strong ly recommend that you have
your oil changed by an authorized
Audi dealer or
a qualified service station .
If you choo se to change your oil your self , please
note the fo llowing important information:
A WARNING
T o red uce the risk of personal injury if you
must c hange the engine oil in your veh icle
yourself:
- Wear eye protection .
-To reduce the risk of bu rns from ho t engine
oi l, let the engine cool down to the touch .
-
-When removing the o il drain pl ug with you r
fingers, stay as far away as possible . A lways
keep your forearm paralle l to the ground to
help prevent hot oi l from running down your
arm.
324
- Drain the oil into a container designed for
this purpose, one large enough to hold at
least the tota l amount of oil in your engine.
- Engine oil is poisonous. Keep it well out of
the reach of children.
- Continuous contact with used engine oi l is
harmf ul to your skin. Always protect your
skin by washing oil off thoroughly with soap
and water .
@ Note
Never mix oil additives with your engine oil.
These additives can damage your engine and
adverse ly affect your Audi Limited New Vehi­
cle Warranty .
{® For the sake of the environment
- Before chang ing your oi l, first make sure
you know where you can properly dispose of
the used oil.
- Always dispose of used eng ine o il properly.
Do not dump it on garden so il, wooded
areas, into open streams or down sewage
dra ins.
- Recycle used eng ine o il by tak ing it to a used
eng ine oi l collect ion fac il ity in your area, or
contact a service station .
Cooling system
Coolant
The engine cooling system is filled w ith a mixture
of purified water and coolant additive at the fac­
tory. This coolant must not be not changed.
The coo lant level is monitored thro ugh
the . in­
dicator light
c> page 25. However, we do recom­
mend occas ionally checking the coolant leve l
manually.
If you must add coo lant, use a mixture of water
and coolant additive . Mix ing the coo lant add itive
with dist illed water is recommended.
1111-

Checking and Filling
Coolan t loss usu ally indicates there is a leak. Im ­
m ed iately drive your v ehicle to an authorized
Aud i dea ler or authorized Aud i Serv ice Facility
and have the cooling system inspected. If the
coo ling system is not leaking, a loss can come
from the coolant boiling through overheating
and be ing pushed out of the cool ing system.
.&_ WARNING
- The coo ling system is under pressure . Do
not open the coolant expans ion tank cap
when the eng ine is ho t. This inc reases the
risk of burns .
- T he coo lant add itive and the coolant can be
d angerous to your healt h. For this reason,
keep the coolant in the origina l container
and away from children . There is a risk of
poisoning .
- When working in the engine compartment,
remember that the rad iator fan can switch
on even if the ign ition is switched off, which
increases the risk of in jury .
-
CD Note
Do not add coolant if the expansion tank is
empty . Air could enter the cooling system and
damage the engine. If this is the case , do not
cont inue driving. See an authorized Audi deal­
er or author ized Audi Service Facility for assis­
tance .
