Catalytic converter
It is very important that your emission con­trol system (catalytic converter) is function­
ing properly to ensure that your vehicle is run­
ning in an environmentally sound manner .
.. Always use lead-free gasoline¢ page 215,
Fuel supply.
.,. Never run the tank down all the way to
empty.
.,. Never put too much motor oil in your en-
gine
¢ page 225, Adding engine oil~-
.,. Never try to push- or tow-start your veh icle.
The catalytic converter is an eff icient "clean­
up" device built into the exhaust system of
the vehicle . The catalytic converter burns
many of the pollutants in the exhaust gas be ­
fore they are released into the atmosphere.
The exclusive use of unleaded fuel is critically
importa nt for the life of the cata lytic convert­
e r and proper functioning of the engine.
A WARNING
-
- Do not park or operate the vehicle in
areas where the hot exhaust system may
come in contact with dry grass, brush,
fuel spill or other material which can cause a fire.
- Do not apply additional undercoating or
rustproofing on or near the exhaust
man ifold, exhaust pipes, catalytic con­
verter or heat shields. During driving, the
substance used for undercoating cou ld
overheat and cause a fire.
0 Note
- Be aware that just one tank filling with
leaded fuel will already seriously de­
grade the performance of the catalytic
converter.
- Do not exceed the correct engine oil level
¢ page 225.
-Do not drive until the fuel tank becomes
completely empty. The eng ine could mis­
fire . U nburned fuel could a lso get i nto
Dri vin g and en vironm ent 195
the exhaust system and this cou ld cause
the catalytic converter to overheat .
- Do not switch off the ignit ion while the
vehicle is mov ing.
- Do not continue to ope rate your veh icle
unde r these conditions, as othe rwise fuel
can reach the catalytic converter. This
co uld result in overheating of the con­
verter, requir ing its replacement .
- To assure efficient operation of the Emis ­
sion Control System:
- H ave your vehicle maintained prope rly
and in accordance w ith the se rv ice rec­
ommendat ions in you r Warranty &
M aintenance boo klet.
- L ack of prope r maintenance as we ll as
improper use of the vehi cle w il l impair
the function of the em ission contro l
system and could lead to damage .
@ For the sake of the environment
Even when the Emiss ion Control System is
operat ing properly, the exha ust gas can
have a sul fur -li ke exhaust gas smell under
some operating states . This depends on
the sulfur content of the fuel being used .
Using a different brand of fue l may help,
or filling the tank with lead-free super
grade gasoline .
Avoid damaging the
vehicle
When you are drivi ng on poo r roads, or over
c ur bs, s teep ramps, etc., ma ke certai n that
low -lying parts s uch as spoilers and exhaust
system pa rts do not bottom o ut and get dam­
aged.
T h is is espec ially true for veh icles w ith low­
s lung chassis (spor ts chassis)* and fully load­
ed vehicles. •

Trailer towing Driving with a trailer
General information
Your Audi was designed primarily for passen­
ger transportation .
If you plan to tow a trai ler, p lease remember
that the addit ional load will affect durab ility,
economy and performance .
Trailer 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 d riving instr uctions provided and use
common sense.
(D Note
If you are going to tow a trai ler, you must
activate the trailer operat ion mode
~ page 199, Operating instructions.
Technical requirements
Trailer hitch
Use a weight-carrying hitc h co nforming 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 the veh icle's chassis at a
technically sound location . Use only a trailer
hi tch wit h a removab le ball moun t. A lways
check with t he trail er hitch ma nufactur er to
make sure tha t you are using the corre ct
hi tch.
Do not use a bumper hitch.
The hitc h must be installed in such a way that
i t does not interfere with the impac t-absorb­
i ng bumpe r sys tem. No mod ifica tio ns should
be made to the vehicle exh aust a nd brake sys­
tems . From time to time, check that a ll hitch
mo unt ing bolts remain securely fastened.
W hen you are not towing a trail er, remove the
traile r hitch ball mount. Th is prevents the
hi tch from causing damage sho uld your ve hi­
cle be str uck from behind ¢& .
Trailer towin g 199
Trailer brakes
If your trailer is equippe d wi th a br akin g sys ­
tem, check to be s ure that i t conforms to all
r egulations .
T he trailer hy draul ic brak e sys tem mus t not be
direc tly connec ted to the vehi cle' s h ydraulic
brake system .
Safety chains
Always use safety chains between your veh icle
and the tra ile r.
Trailer lights
Trai ler lights must meet all regu lations. Be
su re to check with your Audi dealer for cor rect
wir ing, swi tches and relays .
Mirrors
If you are unable to see the traffic behind you
us ing the reg ular o utside mirrors, then you
must insta ll extended mirrors. It is imp ortant
that you
always have clea r v is ion to the rear.
A WARNING ...__ -
Afte r removing the trailer hitch, do not
stor e it i n yo ur v ehicl e. In cas e o f sudden
b ra king, the hitch co uld fly forwar d and in­
ju re you or your p ass en ger s.

Engine cooling sy stem
Towing a tra iler makes the eng ine work hard­
er . It is important that the cooling system's
performance is up to the addit ional load .
Make sure that the cooling system has eno ugh
flu id.
Tir e pressure
When tow ing a tra iler, inflate the t ires of your
vehicle to the co ld tire pressure listed under
" Full load" on the label loca ted o n the dr iver's
side B-pillar (v is ible when the door is open).
I nflate trailer tires to tra iler and tire manufac­
turers' specifications.
Lights
Check to make sure both veh icle and trailer
l ights are wor king p roperly.
Safe ty chain s
Be sure tra iler safety cha ins are properly con­
nected from the trailer to the hitch on the ve ­
h icle . Leave enough slack in the chains to per­
mit turning corners. When you install safety
cha ins, make sure they w ill not drag on the
road when yo u are driving.
The chains shou ld cross under the tra iler
tongue to prevent it from dropping in case of
separat ion from the hitch .
Adjusting the Audi drive select
Make sure the vehicle is on a level surface be­
for e
hitching up the tra iler and b efor e adjust ­
ing the tongue weight . The vehicle must be i n
auto or comfort driving mode and not raised

(D Note
-Changes in temperature or load can af­
fect the height of the vehicle .
- Always select auto or comfort mode .
Otherwise, the tongue load specified for
your vehicle will no longer be applicable.
Driving instructions
Driving with a trailer always requires extra
core and consideration.
T o obtain the best possible hand ling of vehicle
and trailer, please note the fo llowing:
.. Do not tow a loaded t railer when you r ca r it­
self is not loaded .
.. Be especially carefu l when passing other ve ­
hicles .
.. Observe speed limits.
.. Do not drive at the maximum permissible
speed .
.. Always apply brakes early .
.. Monitor the temperature gauge .
Weight distribut ion
T owing a loaded trailer with an empty car re ­
s ul ts in a highly unstable distribution of
weight. If this cannot be avoided, drive at very
low speeds only to avoid the risk of losing
steering control.
A "balanced" rig is easier to operate and con­
trol. This means that the tow vehicle should
be loaded to the extent possible and permissi­
ble , while keep ing the trailer as light as possi­
ble under the ci rcumstances. Whenever poss i­
ble, transfer some cargo to the luggage com­
partment of the tow vehicle while obse rv ing
tong ue load requi rements and vehicle load ing
considerations .
Speed
The higher the speed, the more d ifficu lt it be­
comes for the driver to control the rig. Do not
1111>

drive at the maximum permissible speed. Re­
duce your speed even more if load, weather or
wind condit ions are unfavorable -part icularly
when going downhill.
Reduce vehicle speed
immediately if the trail­
er shows the slightest sign of swaying .
Do not
try to stop the swaying by accelerating.
Observe speed limits . In some areas, speeds
for vehicles towing trailers are lower than for
regular vehicles .
A lways apply brakes early. When driving
downhill, shift into a lower gear to use the en­
gine braking effect to slow the vehicle . Use of
the brakes a lone can cause them to overheat
and fail.
Coolant temperature
The coolant temperature gauge c:> page 10
must be observed carefully. The coo lant tem­
perature can increase if you drive on long in ­
clines in a low gear at high engine speeds. Re­
duce your speed immed iate ly if the L EDs in
the top part of the display turn on.
F or more information about indicator lights,
refer to.

A WARNING
Anyone not properly restrained in a mov­
ing vehicle is at a much greater risk in an
accident . Never let anyone r ide in your car
who is not properly wear ing the restra ints
provided by Aud i.
Trailer towing tips
Important to know
Your veh icle hand les different ly when tow ing
-
a trailer because of the addit ional weight and
d ifferent weight distribution . Safety, perform­
ance and economy will greatly depend on how
carefully you load your trailer and operate
your ng .
Before you actually tow your trailer, practice
turning, stopp ing and back ing up in an area
away from traffic. Keep practicing until you
Trailer towing 201
have become completely familiar with the way
your vehicle-trai ler combination behaves and
responds .
Backing up is difficult and requires practice .
Backing up with a t railer generally requires
steering action opposite to that when backing
up your vehicle without a tra iler.
Maintain a greater distance between your ve­
hicle and the one in front of you . You wi ll need
more room to stop. To compensate for the
trailer, you w ill need a larger than normal
turning rad ius.
When passing, remembe r that you cannot ac­
ce lerate as fast as you norma lly would be­
cause of the added load. Make sure you have
enough room to pass. After passing, allow plenty of room for your trailer 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
c:> page 280.
Parking on a slope
Do not park on a slope with a trailer. If it can­
not be avoided, do so only a~er doing the fol­
lowing:
When parking:
.,. App ly the foot brake.
.,. Have someone p lace chocks under both the
vehicle and the trailer wheels .
.,. 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 posit ion .
When restarting after parking:
.,. Apply the foot brake.

Care and handling
Because of the exclusive nature of the types of
leather 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 with these leathers, and a certain type of
care is required. For examp le, dark cloth ing
materials can d iscolor leather seats (especial­
ly if such cloth ing is damp and was not dyed
correctly) . Dust and d irt part icles in pores,
fo lds, and seams can have a n ab ras ive effect
and can damage the leathe r sur face as well as
weaken seams.
The leather should be cleaned regularly as
n eeded . After having been used for a re lative ly
long t ime, yo ur leather seats will acqui re a
rich aged finish. This is a characteristic of nat­
ura l leather and a sign o f true quality .
I n o rder to maintain the va lue of th is natura l
p rod uct over the life of yo ur vehicle, you
should follow the recommendations below :
(D Note
-To keep you r leather from bleach ing out,
do not a llow i t to be exposed to bright
s unli ght 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
l eave permanent scratches or scrape
marks on the surface of the leather.
(D} Tips
- After each time you clean the leather and
at regular interva ls, use a leather preser­
vat ive creme that conta ins UV-blockers
and that works into the leather . This
creme w ill nou rish and moistur ize the
l eather, helping it to b reath e and stay
supple. It al so helps to b uild up a pro tec­
tive coat ing o n the s urface.
- Clean the leathe r every 2 -3 months,
and clean a ny a reas that get soiled .
Cleaning and protec tion 21 1
- Remove fresh ma rks made by ballpo int
pens, ink, lipstick, shoe po lish, 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
App lies to vehicles: with natural leather
Natural leather requires special care and a t­
tention .
Normal clean ing
.. Clean soiled areas with a slightly moistened
cotton or woolen cloth .
More stubborn dirt
.,. More s tubborn di rt ca n be removed using a
cloth sa turated wi th a mild soap sol ution (2
tablespoons mild liq ui d soap) .
.. Never a llow the soap so lution to saturate
the leather, and make certain that no water
s oak s in to the seam s.
.,. Wipe off the soap so lu tion with a soft, d ry
cloth .
Cleaning spots
.. Remove fresh wate r-based spots (such as
coffee, tea, juices, blood) with an absorbent
cloth or paper towel.
.,. Remove fresh
grease or oil -based spots
(such as butter , mayonnaise, chocolate) with
an absorbent clot h or paper towel, or use
the cleaner from the leather care kit if the
spot has no t yet penetrated into t he surface
of the leather .
.,. Use an oil/grease dissolving spray, i f
oil/
grease spot s have d ried on.
.. Remove specific kinds of spots (ballpoint
pen, fe lt marker, fingerna il polish, water ­
based pa int, shoe po lish, etc.) with a spot
remover specifically formu lated for lea ther.
Leather care
.. Every half yea r use an approved leather care
product (available from your Audi dea ler) to
care for the leather . .,.

Tires and vehicle load limits
There are limits to the amount of load or
weight that any vehicle and any t ire can carry.
A vehicle that is overloaded w ill not handle
well and is more difficult to stop. Overload ing
can not only lead to loss of vehicle control, but can a lso damage importan t pa rts of the
ve hicle and can lead to s udden tire failure, in­
cluding a blowout and sudden deflation that
can cause the veh icle to crash.
Your safety and that of yo ur passenge rs a lso
depends on making s ure that load limits are
not exceeded. Vehicle load includes everybody
and everything in and on the vehicle. These
load limits are technica lly referred to as the
vehicle's
Gros s Vehicle We ight R ating
("GVWR").
The "GVWR" includes the weight of the basic
vehicle, all factory insta lled accessories, a full
tank of fue l, oil, coolant and other fluids plus
maximum load. The maximum load includes
the number of passengers that the vehicle is intended to carry ("seating capacity") with an
assumed weight of 150 lbs (68 kg) for each
passenger at a des ignated seat ing pos ition
and the total we ight of any l uggage in the ve­
hi cle. If you tow a trailer, the weight of the
trailer hitch and the tongue weight of the loaded trailer must be included as part of the
vehicle load.
The
Gro ss Axl e W eight R ating ("GAWR") is
the maximum load that can be app lied at each
of the vehicle's two axles.
The Gross Vehicle Weight Rating and the
Gross Axle Weight Rating a re listed on the
safety compliance sticker labe l located on the
driver's side B -pillar . Your Audi has 5 seating
positions, 2 in the front and 3 in the rear for
total seating capacity of 5. Vehicles with pow­
er individual rear seats* have 4 seating posi­
tions, 2 in the front and 2 in the rear for total
Tire s an d wheel s 243
seating capacity o f 4 . Each seating position
has a safety belt~ page 134, Safety belts .
T he fact th at there is a n upper limit to yo ur
vehicle's G ross Vehicle Weight Rating means
that the total weight of whatever is being car­
ried in the vehicle (including the weight of a
tra iler hitch and the tongue weight of the
l oaded tra iler) is lim ited. The more passen­
gers in the vehicle or passengers who are
heavier than the standard we ights assumed
mea n that less we ight can be carried as lug­
gage .
The tire pressure label on your Audi also lists
the maximum combined weight of all of the
occupants and luggage or other cargo that
the vehicle can carry . For the locat ion of the
label ~page239, fig.183.
A WARNING
Overloading a vehicle can cause loss of ve­
hicle contro l, a crash or other accident, se­
rious personal injury, and even death.
- Ca rrying more we igh t than your veh icle
was des igned to carry wi ll prevent the
vehicle from handling properly and in ­
crease the risk of the loss of vehicle con­
trol.
- The brakes on a vehicle that has been
overloaded may not be able to stop the
veh icle w ith in a safe distance.
- Tires on a vehicle that has been over load­
ed can fail suddenly, incl uding a blowout
and sudden deflation, causing loss of
control and a crash .
- Always make sure that the total load be­
ing transported -includ ing the weight of
a trailer hitch and the tongue we ight of a
loaded trailer -does not make t he vehi­
cle heavier than the vehicle's Gross Vehi­
cle Weight Rating.
