Trailer towing Driving with a trailer
General information
Your Audi was designed primarily for passen­
ger transportation .
If you plan to tow a tra iler, p lease remember
that the addit ional load will affect durab ility,
economy and performance .
T railer towing not on ly places more stress on
the vehicle, it also calls for more concentra­
tion from the driver.
F or this reason, a lways fo llow the operating
and driving instructions provided and use
common sense.
Technical requirements
Traile r hitch
Use a weight-carrying hitch conforming to the
gross trailer we ight. The hitch must be suita­
b le for your veh icle and trailer and must be
mounted secure ly on t he veh icle's chassis at a
technically sound location . Use only a t railer
h itch w ith a removab le ball moun t. A lways
check with the tr ailer hitch man ufac tur er to
make sure that you are using the correct
hitch.
Do not use a bumper hitch.
T he hitc h must be installed in such a way that
it does not inte rfe re with the impac t-absorb­
i ng b umper syst em. No modifica tions should
be made to the vehicle exhaus t and b rake sys­
tems . From t ime to time, check that a ll hitch
mo unt ing bolt s remain securely fas tened.
W hen you are not tow ing a trailer, remove the
trai le r hi tch ball moun t. T h is prevents the
hi tch from causing damage sho uld your ve hi­
cle be str uck from be hind
¢ &. .
Trailer brakes
If yo ur tra iler is equ ipped w it h a braking sys­
tem, check to be su re that it conforms to a ll
r eg ulat io ns.
Trailer towin g 197
The trailer hyd ra ulic bra ke system must not be
direct ly connected to the vehicle's hydraulic
brake system .
Safety chains
Alw ays use saf ety chains between your ve hicle
and t he tra ile r.
Trailer lights
Tra iler lights must meet all reg ulations . Be
su re to check with your Audi dea ler fo r cor re ct
wir ing, swi tches and relays.
Mirrors
If you a re unable to see the traffic behind you
u sing the regula r outside m irrors, then you
must i nsta ll ext ended mir rors . It is important
t h at you
always have clea r vis ion to the rear .
.8, WARNING
-
Afte r removing the trailer hit ch, do no t
s tore i t in yo ur vehicle . In case of sudden
b raking, the h itch cou ld fly forwar d an d in­
ju re you or yo ur passengers .
Operating instructions
Maximum trailer weight
A tra ile r fo r you r vehicle is limited to a ty pical
cl ass 1 or class 2 tra ile r.
Trailer load distribution
B e sure the loa d in the tr aile r is held secure ly
i n place to p reven t it from shift ing forw ard,
ba ckward or sideways.
Never allow a passenger to ride in a trailer
¢&. in Driving instru ctions on page 198.
Engine cooling system
Towing a trailer makes the engine work hard­
er . It is impo rtant that the cooling system's
perfo rmance is up to the additional load .
Make sure that the coo ling syst em has enough
f lui d.
Tire pressure
When towing a trailer , inflate the tires of your
vehicle to t he cold tire pressure listed under .,..

different weight distribution. Safety, perform­
ance and economy wi ll greatly depend on how
carefu lly you load your trailer and operate
your rig.
Before you actua lly tow your trailer, practice
turning, stopping and backing up in an area
away from traffic. Keep practicing until you
have become comp letely fam iliar with the way
your vehicle- trailer combination behaves and
responds .
Backing up is d ifficult and requires practice.
Backing up with a trai ler generally requires
steering action opposite to that when backing up your vehicle without a trailer .
Maintain a greater distance between your ve­
hicle and the one in front of you. You will need
more room to stop. To compensate for the
trailer, you will need a larger than normal
turn ing radius.
When passing, remember that you cannot ac­
celerate as fast as you normally would be­
cause of the added load. Make sure you have
enough room to pass . After passing, allow
p lenty of room for your tra iler before chang­
ing lanes again.
Avoid jerky starts, sharp turns or rapid lane
changes.
(D Tips
- Do not tow a trailer during the break- in
period of your vehicle.
- If you tow a trailer, your Audi may re­
quire more frequent maintenance due to
the extra load
¢ page 2 73 .
Parking on a slope
Do not park on a slope with a trailer. If i t can­
not be avoided, do so only after doing the fol ­
lowing:
When parking:
.. Apply the foot brake .
.. Have someone place chocks under both the
vehicle and the trailer wheels.
Trailer towing 199
.. With chocks in place, slowly release the
brakes until the wheel chocks absorb the
load .
.. Turn the wheels towards the curb .
.. Apply the parking brake.
.. Select the
P selector lever position .
When restarting after parking:
.. App ly the foot brake.
.. Start the engine .
.. Select the
D/S selector lever position.
.. Release the parking brake and slowly pull
out and away from the wheel chocks .
.. Stop and have someone retr ieve the wheel
chocks.
(D Tips
If you move the selector lever of the auto­
matic transmission to
P before applying
the pa rking brake and before blocking the
whee ls, you may have to use more force
lat er to move the lever out of the
P posi­
tion.

206 Cleaning and protec tio n
-Always read and heed all WARNINGS and
other information
c> page 200.
Exhaust tail pipes
Road salt and other corrosive materials will
damage the material in the exhaust tail pipes
if they are not cleaned regularly . Do not clean
the tail p ipes with wheel cleaner, paint pol ish,
chrome po lish or other abrasive cleaners.
C lean the tail p ipes with car ca re p roducts
that are su itable for stain less stee l.
Your author ized Audi dealer can provide clean­
ing p roducts that have been tested and ap­
p roved fo r you r vehicle.
Care of interior
Infotainment components
The MMI/RSE* display may be cleaned with a
soft cloth and commercially-ava ilable "LCD
cleaner" . The cloth should be coated lightly
when the clean ing solution when cleaning the
d isplay.
The MMI/RSE* contro ls must be cleaned first
with a brush so t hat dirt does not ente r the
un it or enter between the buttons and the
housing. Then wiping the controls with a cloth
dampened with dish detergent and water is recommended.
CJ) Note
- To avoid sc ratch ing the disp lay, you
shou ld never clean it dry.
- To prevent damage, ma ke sure fluids do
not enter the controls.
Aluminum trim
Use only n eutral-pH products to remove spots
and deposits from aluminum surfaces.
Chrome care products and alkaline cleaners
will attack aluminum s urfaces and can dam­
age them over time.
A WARNING
A lways read and heed all WARNINGS and
other information
c> page 200.
Fabrics and fabric coverings
Fabr ics and fabric cover ings (e .g. seats, door
trim panels, etc.) should be cleaned at regular i ntervals w ith a vacuum cleaner. This removes
su rface di rt particles which could become em ­
bedded in the fabric through use. Steam
cleaners should not be used, because the
steam tends to p ush the dirt deeper into the
fabric and lock it there.
Normal clean ing
Generally, we recommend using a soft sponge
o r a lint-free microfiber cloth to the clean fab­
ric. Brushes shou ld only be used for carpets
and floor mats, since other fabric surfaces
could be harmed by brushes.
Norma l su rface stains can be cleaned using a
commercially available foam cleaner . Spread
the foam on the s urface of the fabric with a
soft sponge and work it in gently. Do not satu­
rate the fabric. Then pat the foam dry using
absorbent, dry cloths (e.g. m icrof iber cloth)
and vacuum it after it has dried completely.
Cle anin g sta ins
Stains caused by beverages (e .g. coffee, fruit
juice, etc.) can be treated with a mild deter­
gent solution. Apply the detergent solution
with a sponge. In the case of stubborn stains, a detergent paste can be applied directly to
the stain and worked into the fabric. After­
wards, use copious amounts of clean water to
remove the rema in ing deterge nt. Apply the
water wit h a damp clo th or sponge and pat
the fabric dry with an abso rbent, dry cloth .
Stains from choco late or makeup should have
detergent paste (e.g. ox-gall soap) rubbed in­
to them. Afterwa rds, remove the soap with
water (damp sponge) .
Alcohol can be used to treat stains from grease, o il, lipstick or a ballpoin t pen . Melted ..,.

208 Clea ning and protec tio n
Care and handling
Because of the exclusive nat ure of the types of
l eather that Audi uses and their unique prop ­
erties (such as sensitivity to oils, grease, soi l­
ing, etc.), you will need to be somewhat care­
fu l w ith these leathers, and a certain type of
care is required. For examp le, dark clothing
materials can d iscolor leather seats (especial­
ly if such cloth ing is damp and was not dyed
correctly). Dust and dirt part icles in pores,
folds, and seams can have an ab ras ive effect
and can damage the leather surface as well as
weaken seams.
The leather should be cleaned regularly as
needed. After having been used for a re latively
long t ime, your leather sea ts will acquire a
rich aged finish. This is a characteristic of nat­
ura l leather and a sign of true quality .
I n order to maintain the va lue of th is natura l
p rod uct over the life of your vehicle, you
should follow the recommendations below :
(D Note
-To keep you r leather from bleaching out,
do not a llow it to be exposed to bright
sunl ight for long periods of time. If you
have to leave the vehicle parked o utside
for long periods, cover the leather to
protect it from d irect exposure to sun­
li ght.
- Sharp objects on clothing, such as zip­
pers, rivets or sharp pieces on be lts can
leave permanent scratches or scrape
marks on the surface of the leather.
- After each time you clean the leather and
at regu lar intervals, use a leather preser­
vat ive creme that conta ins UV-blockers
and that works into the leather. This
creme wi ll nourish and moistur ize the
l eather, helping it to b reathe and stay
supple.
It also helps to bu ild up a protec­
tive coat ing on the s urface.
- Clean the leather every 2 -3 months,
and clean any areas that get soiled. - Remove fresh marks made by ballpoint
pens, ink, lipstick, shoe polish, etc. as
soon as poss ible.
- Preserve the color of the leather as need­
ed by using a specia l co lored leather care
creme to touch up areas of uneven color.
Cleaning and caring for leather
upholstery and trim
Applies to vehicles: with natural leather
Natural lea ther requires special care and a t­
tention .
Normal cl ean ing
.. Clean soiled areas with a slightly moistened
cotton or woolen cloth .
More stubborn dirt
.. More s tubbor n dirt ca n be removed using a
cloth saturated with a mild soap solut ion (2
tablespoons mild liquid soap).
.. Never allow the soap solution to saturate
the leath er, and make certain that no water
soak s into the seam s.
.. Wipe off the soap solution with a soft, dry
cloth .
Cleanin g spot s
.. Remove fresh wate r-b as ed spots (such as
coffee, tea, juices, blood) with an absorbent
cloth or paper towel.
.. Remove fresh
grease or oil -b ased spots
(such as butter, mayonnaise, chocolate) with
an absorbent cloth or paper towel, or use
the cleaner from the leather care kit if the
spot has no t yet penetrated into the surface
of the leathe r .
.. Use an oil/grease d issolving spray, if
o il/
grea se sp ots ha ve d ried on.
.. Remove specific kinds of spots (ballpoint
pen, fe lt marker, fingerna il polish, water­
based pa int, shoe polish, etc.) with a spot
remover specifically formulated for lea ther.
L e athe r care
.. Every half year use an approved leather care
product (available from your Audi dealer) to
care for the leather . .,.

226 Check ing and filling
Before you check anything in the engine com­
partment,
always r ea d and heed all W ARN­
INGS
¢ A in Working in the engine compart­
ment on page 216.
• Read the brake fluid leve l from the brake
fluid reservoir
¢ fig. 173. The brake fluid
l evel must be between the
"MIN" and
"MAX" markings .
The location of the brake fluid reservoir can be
seen in the engine compartment illustration
co page 218.
The fl uid level may drop slightly after some
time due to the automatic adjustment of the brake pads . This is not cause for alarm .
I f the b rake fluid level falls
considerably be­
l ow the "MIN" mark, the brake wa rning/indi ­
cator light- (U.S.
models) ;II (Canadian
models) will come on
¢ page 14. Do not con ­
tinue to operate the vehicle. The comp lete
brake system shou ld be thoroughly checked
by an authorized Audi dealer or other quali­
fied fac il ity and the cause corrected. If the
brake fluid level is too low, the brake warn ing/
i ndicator light w ill illuminate. Contact an au­
thor ized Audi dealer
imm ediatel y.
Changing brake fluid
Have the brake fluid changed by an experi­
enced technician .
Brake fluid absorbs moistu re from the a ir . If
the water content in the brake fluid is too
h igh, corrosion in the brake system may result
after a per iod of t ime . The bo iling po int of the
b rake fluid w ill also decrease considerably and
dec rease braking per formance.
Therefore, the brake flu id must be changed
ev ery tw o y ear s. Always use new b rake fluid
which confo rms to Fede ral Motor Vehicle
Standard "FMVSS 1 16 DO T 4".
The brake flu id rese rvoi r can be difficult to
r each, therefo re , we re commend that yo u
have the brake fl uid changed by yo ur a utho r­
ized
Audi dealer. Your dea ler has the correct tools, the
right brake flu id and t he know -how
to do this for you.
A WARNING
-- Brake flu id is poisonous. It must be stor-
ed only in the closed or igina l container
out of the reach of children!
- Brake failure can resu lt from o ld or inap­
propriate brake f lu id. Observe these pre­
cautions:
- Use only brake f luid that meets SA E
spe cifi cation
J 17 03 and conforms to
Federa l Motor Vehicle Standard 1 16 .
Always chec k with your authorized A udi
dealer to make sure yo u are using the
correct brake fluid. The cor rect type of
brake flu id is also ind icated on the
brake f lu id reservoir.
- The brake fluid must be new. Heavy use
of the brakes can cause a vapor lock if
the brake fluid is left i n the system too
long . This can se riously affect the effi­
c iency of the brakes as well as your
safety . T h is i:ou ld result in an ai;i;ident.
(D Note
Brake fluid will damage the pai nt of you r
vehicle .
@ For the sake of the environment
Because of the prob lem of proper disposal
of brake fluid as well as the spec ial too ls
r equired and the necessary expertise, we
r ecommend that yo u have the brake flu id
changed by yo ur autho rized Aud i dea le r.
Battery
General information
Under normal operat ing cond itions, the bat­
te ry in your Audi does not need any ma inte­
nance. With
high outside temperatures or
long da ily drives we recommend that you have
the e lectrolyte leve l che cked by a se rv ice fa­
c il ity. The electroly te leve l should also be
chec ked each time the battery is cha rged
¢ page 22 9.

Have the battery checked when you take your
vehicle in for service. Yo u are well advised to
replace a battery that is older than 5 years.
W ith certa in types o f airbag deployment, the
battery is disconnec ted from the vehicle elec ­
trica l system for safety reasons
c::> &. in Re­
pair, care and disposal of the airbags on
page 153.
Di sconn ecting the battery t erminal s
Some vehicle functions (power w indow regu­
l ators, for example) are lost if the battery ter­
minals are disconnected . These functions have
to be re learned after the battery terminals are
connec ted again. To prevent this, the battery
should only be disconnected from the vehicle
e lectrical system when absolutely necessary
for repairs .
Vehicl es not driven for long p eriod s
If you do not drive your vehicle over a period
of several days or weeks, electrical compo­
nents are gradually cu t back or switched off .
This reduces energy consumption and main ­
tains starting capability over a longer per iod
c::> page 190. Some of the convenience func­
tions may not operate, s uch as the inte rior
lights o r power seat adjus tme nt. The conven­
ience functions will be ava ilable again when
you switch on the ignition and start the en­ gine.
Winter operation
During the winter months, ba ttery capaci ty
t ends to decrease as tempe rat ures d rop . This
is because more powe r is also consumed while
starting , and the headlights, rear window de ­
fogger, etc., are used more often.
Avoid unnecessary power cons umption, par­
ticularly in c ity t ra ff ic or when t raveling on ly
short distances. Let your a uthorized Audi
dealer check the capac ity of the vehicle bat ­
tery before winter sets in
c> page 229. A well
charged battery w ill not only prevent starting
problems whe n the weather is cold, but will
also last longer .
Checkin g and fillin g 22 7
(D Tips
If your vehicle is left standing for seve ral
weeks at extremely low temperatures, the
vehicle battery shou ld be removed and
stored where it w ill not freeze. This will
prevent it from be ing damaged and having
to be replaced .
Working on the battery
Be especially careful when working on or near
the battery.
The battery is located in the l uggage compart­
ment under the floor. Before you check any­
th ing in the luggage compartment,
read and
h eed all WARNINGS

250 Tires and wheels
When the malfunction indicator is illuminat­
ed, the system may not be able to detect or
signal low tire pressure as intended . TPMS
malfunctions may occur for a variety of rea­
sons, including the installation of replace­ ment or alternate tires or wheels on the vehi ­
cle that prevent the TPMS from funct ioning
properly . Always check the TPMS malfunction
telltale after replacing one or more t ires or
wheels on your veh icle to ensure that the re­
p lacement or a lternate tires and wheels allow
the TPMS to continue to function properly.
Tire pressure indicator appears
Applies to vehicles: with tire p ressure mo nitoring syste m
The tire pressure indicator in the instrument
cluster informs you if the tire pressure is too
low or if there is a system malfunction.
Fig. 181 Display : underinflatio n warning
Fig. 182 Display : Syste m mal functio n
Using the ABS sensors, the tire pressure moni­
toring system compares the tire tread circum­
ference and vibration characteristics of the in­
d ividual tires.
If the pressure decreases in one
or more tires, th is is indicated in the instru­
ment cluster with a warning symbol
'9] and a
message ¢
fig . 181.
The tire pressure monitoring system must be
reset via MMI each time the pressures are ad- justed
(e.g. when switching between partial
and full load pressure) or after changing or re­
placing a tire on your vehicle ¢
page 251. You
can find the recommended tire pressures for
your vehicle on the label on driver 's side B-pil­
lar ¢
page 235 .
Tire tread circumference and vibration charac­
teristics can change and cause a tire pressure
warning if:
- the tire pressure in one or more tires is too
low,
- the tire has structural damage,
- the tire pressure was changed, wheels rotat -
ed or replaced but the TPMS was not reset
¢page 251.
Warning symbols
'9] Loss of pressu re in at least one tir e ¢ & .
Check the tire or tires and replace or repa ir if
necessary. The indicator light
'9] in the instru­
ment cluster also illuminates
¢page 11.
Check/correct the pressures of all four tires
and reset TPMS via MMI.
••MIS, ( Ti re Pressure Monitoring System) Tire
pressure! System malfunction .
If IIMIS, appears after switching the ignition
on or while driving¢
fig. 182 and the indica­
tor light
'9] in the instrument cluster blinks
f or approximately one minute and then stays
on, there is a system malfunction . See your
authorized Audi dea ler as soon as possible .
A WARNING
--If the tire pressure indicator appears in
the instrument cluster display, one or more of your tires is significant ly under­
inflated. Reduce you r speed immediately
and avoid any hard steer ing or braking
maneuvers. Stop as soon as possible and
check the tires and their pressures. In­
flate the tire pressure to the proper pres­
sure as indicated on the vehicle's tire
pressure label¢
page 235. Driving on a
significantly under- inflated tire causes
the tire to overheat and can lead to tire
failure. Under-inflation also is likely to
