Vehicle care and clean ing
General information
Regular, proper care helps to maintain your
vehicle 's value. It can also be a requirement
when submitting warranty claims for corro
sion damage and paint defects on the body .
The required cleaning and care products can
be obtained from your authorized Audi dealer
or a qualified workshop . Read and follow the
instructions for use on the packaging.
A WARNING
-Us ing clean ing and care products incor
rectly can be dangerous to your hea lth.
- Always store cleaning and care products
out of reach of children to reduce the risk
of poisoning.
@) For the sake of the environment
-Preferably use environmentally-friendly
products when buying cleaning agents.
- Do not d ispose of leftover cleaning and
care products with household trash .
Car washes
-
The longer that deposits such as insects, bird
droppings, tree sap or road salt remain on the
vehicle, the more the surface can be dam aged. High temperatures such as those
caused by sunlight increase the corrosive ef
fect.
Before washing, wet heavy deposits w ith plen
ty of water.
Also, wash the underside of your vehicle once road salt stops be ing used for the season.
Pressure washers
When washing your vehicles with a pressure
washer, always follow the operating instruc
tions provided w ith the pressure washer . Th is
is especially important in regard to the pres
sure and spraying distance. Do not aim the
spray directly at seals on side w indows, doors,
Vehicle care and cleaning 213
the hood, the rear lid or the sunroof* or at
tires, rubber hoses, insulating material, sen sors* or camera lenses* . Keep a distance of at
least 16 inches (40 cm).
Do not remove snow and ice with a pressure
washer.
Never use rotary nozzles or high pressure noz
zles.
The water temperature must not be above
140 °F (60 °C) .
Automatic car washes
Spray off the vehicle before washing.
Make sure that the windows and roof* are
closed and the windshield wipers are
off. Fol
low instructions from the car wash operator,
especially if there are accessories attached to
your vehicle.
If possible, use car washes that do not have
brushes .
Washing by hand
Clean the vehicle starting from the top and
working down using a soft sponge or cleaning
brush. Use solvent-free cleaning products.
Washing vehicles with matte finish paint
by hand
To avoid damaging the paint when washing,
first remove dust and large particles from
your vehicle. Insects, grease spots and finger prints are best removed with a special cleaner
for matte finish paint.
Apply the product using a microfiber cloth. To
avoid damaging the paint surface, do not use
too much pressure .
Rinse the vehicle thoroughly with water. Then
clean using a neutral shampoo and a soft mi
crof iber cloth.
Rinse the vehicle thoroughly again and let it
air dry . Remove any water residue using a
shammy.
Stubborn deposits such as bi rd droppings or
tree sap are best removed with plenty of wa-
ter and a microfiber cloth.

Tires
General notes
Tires may be the least appreciated and most
abused parts of a motor vehicle .
Tires may be the least appreciated and most
abused parts of a motor vehicle . Tires are,
however, one of the most important parts of a
vehicle, particularly considering the compara
tively small patch of rubber on each tire that
assures that a ll- important contact between
you, your vehicle and the road.
Maintaining the correct tire pressure, mak ing
sure that your vehicle and its tires do not have
to carry mo re weight than they can safely han
d le, avoiding damage from road hazards and
r eg ularly inspect ing t ires for damage i nclud
ing cuts, slashes irregu la r wear and ove rall
condition are the most important things that
you can do to he lp avoid sudden tire failure in
cluding tread separat ion and blowouts.
A voidin g damage
If you have to d rive over a curb or similar ob
stacle, drive very slow ly and as close as possi
b le at a right angle to the curb.
A lways keep chemicals includ ing grease, o il ,
gasoline and brake fluid off the t ires .
I nspect the t ires regularly for damage (cuts,
cracks or b listers, etc.). Remove any fo reign
bod ies embedde d in the treads.
Storing tires Mark tires when you remove them to indicate
the direction of rotation . T his ensures you to
be ab le to mount them correctly when you re
i nstall them .
When removed, the wheels or t ires should be
sto red in a cool, d ry and preferably dark place .
Store tires in a vertical pos ition if they are not
mounted on rims, in a horizontal pos it ion if
they are mounted on rims .
Tires an d wheel s 243
New tires
New ti res have to be broken in¢& .
The tread depth of new t ires may vary, accord
ing to the type a nd make of t ire and the tread
patte rn.
H idden damage
Damage to tires and r ims is ofte n not readily
visible . If you notice unusual v ib rat ion or the
vehicle pulls to one s ide, th is may ind icate
that one of the t ires has been damaged . T he
ti res m ust be chec ked immed iate ly by an au
thorized Audi dea le r or q ua lified wor kshop .
Unidirectional tires
A un idirectional tire can be identified by ar
rows on the sidewa ll, that po int in the direc
tion the t ire is designed to rotate. You mus t
f ol low the specified di rection o f rotation . T his
is necessary so that these tires can develop
their optimum characteristics regarding grip, road noise, wear and hydrop laning resistance.
For more information
¢ page 271.
A WARNING
New tires or t ires that are o ld, worn or
damaged cannot provide maximum con
trol and braking ability .
-
-New tires tend to be slippery and must
be broken in. To reduce the r isk of losing
control, a co llision and ser ious personal
in ju ries, d rive with special ca re for the
fi rst 350 m iles ( 560 km).
- Driving with worn or damaged tires can
lead to loss of control, sudden tire fail
ure, including a blowout and sudden de
fl ation, cras hes and se riou s personal in
juries . Have worn or damaged t ires re
placed immediate ly.
- Ti res age even if they are not being used
and can fai l sudden ly, especially at hig h
speeds. Tires that are more than 6 years
old can only be used in an emergency
and then w ith special care and at low
speed.

24 4 T ire s and wheel s
-Never mount used tires on yo ur vehicle if
you are not sure of their "previous histo
ry." Old used tires may have been dam
aged even though the damage cannot be
seen that can lead to sudden t ire failure
and loss of vehicle control.
- If you notice unusual vibration or if the
vehicle pulls to one side when driving, al
ways stop as soon as it is safe to do so
and check the wheels and tires for dam
age.

Cold tire inflation pressure
Tire pressure affects the overall handling, performance and safety of a vehicle.

p ill ar
Tire pressure generally refers to the amo unt
of air in a t ire that it needs it to do its job and
safely car ry the combined load of the entire
vehicle and its contents . T ire pressure is
measured in kilopascals (kPa) , the interna
tional measu ring unit and in pounds per
s quare inch (PSI). Tire p ressure is based in
part on the vehicle's design and load limit -
the greatest amount of weight that the vehi
cle can carry safely and the t ire size . The prop
er tire pressure is frequent ly referred to as the
" recommended cold tire inf lation pressure ."
Air in the tires expands when the ti re heats up
beca use of internal fri ct ion when it flexes in
use. The tire p ressure is higher when the tire
has warmed up than when it is "cold ." It is the
inflat ion p ressure in a "cold" ti re that counts.
Therefore, you should never let air out of a
warm tire to match "cold tire inflation p res
sure" recommendations. The t ires would then
be underinflated and could fail suddenly .
Maintaining proper tire pre ssure is one of the
most important things you can do to help
avoid sudde n tire failure . Underinflated t ires
are a majo r cause of sudden tire failure . Keep
i ng tires at the r ight pressure is also impor-

Checking tire pressure
The correct tire pressure for the tires original
ly installed on your vehicle is listed on the tire
pressure label located on driver's side 8-pil lar.
The recommended tire pressures are on the
t ire p ress ure label and i n the table
¢ page 247, Cold tire inflation pressure.This
means th at the pressure m ust be chec ked and
adjusted when the t ire has not been dr iven for
more than a couple of miles (kilometers) at

Air in the tires expands when the tire heats up
as a result of internal frict ion as it flexes in
use. The tire pressure is higher when the tire
has warmed up than when it is "cold."
It is the inflation pressure in a "cold" tire that
counts. Therefore, you should never let a ir out

used today are underinflated just by looking
at them.
Therefore, be sure to check tire pressures at least once a month and always before going
on a long tr ip. Make sure to take the number
of people and the amount of luggage into ac
count when adjusting tire pressure for a trip -
even one that you would not consider to be
"long." See
c> page 251, Tires and vehicle
load limits
for more important information .
Always use an accurate tire pressure gauge
when checking and adjusting inflation pres
sures . Check all of the t ires and be sure not to
forget the spare tire . If the pressure in any tire
i s too high when the tire is "cold," let air out
of the tire slowly with the edge of the tire
gauge and keep checking the pressure unt il
you reach the pressu re that is correct for the
l oad (passengers and luggage) and kind of
driving you plan to do.
I f the p ress ure in any tire is too low, note the
d ifference between the pressure in the cold
tire and the pressure you need and add the a ir
that you need to reach the correct pressure for
the vehicle load (passengers and luggage) for
the tires on your veh icle as listed on the on
you r veh icle and in this manual and the k ind
of dr iving you plan to do.
Ne ver e xceed the m aximum inflation pre s
su re li sted on the ti re sidewall for an y rea
son.
Remember that the vehicle manufacturer, not
the tire manufacturer, determines the correct
tire p ressure fo r the t ires on your vehicle .
It is important to check the tire pressu re when
the tires are cold.
- Read the requ ired t ire p ress ure from the tire
pressure label. The ti re pressu re labe l is lo
cated on the drive r's side 8-pi llar.
- T urn the valve stem cap counter- clockwise
to remove i t from the tire valve.
- Place the air pressu re gauge on the valve .
- The tire pressures should only be checked
and adjusted when the tires a re cold . The slightly raised pressures of warm tires must
not be reduced.
- Adjust the tire pressure to the load you are
carrying.
- Reins tall the valve stem cap on the va lve.
When sh ould I check the tire pressure?
The correct tire pressure is especially impor
tant at h igh speeds. The pressure should
the refore be checked at least once a mo nth
and always before starting a jo urney. Do not
f orget to c heck the ti re p ress ure fo r the spare
whee l
i=;,poge 265.
When should I adjust the tire pressures?
Adjust the tire pressure to the load you are
ca rrying. After changing a whee l
or replaci ng
whee ls yo u have to adj ust the ti re press ures
on all whee ls. In addition, you m ust then
store the new tire pressures in the tire pres
s u re monito ring system*

A WARNING ~
Incorrect tire pressures and/or underinfla-
tion can lead sudden tire fa ilure, loss of
control, collision, serious personal injury
or even death.
- When the warn ing symbol
RI] appears in
the instrument cluster, stop and inspect
the t ires.
- Incorrect tire pressure and/or underinfla
tion can cause increased tire wear and can affect the handling of the vehicle and
stopping ability .
- Inco rrect tire pressures and/or underin
flation can a lso lead to sudden t ire fail
ure, including a blowou t and sudden de
flation, ca us ing loss of veh icle cont ro l.
- The drive r is responsible for the co rrect
tire pressures for all tires on the veh icle.
T he applicable pressure values are loca t
ed on a sticke r on the dr iver's s ide 8-pil
lar .
- On ly when all tires on the vehicle are fil
led to the correct pressu re, the t ire pres
sure monitoring* system can work cor rectly.

-The use of incorrect tire pressure values
can lead to accidents or other damage.
Therefore it is essential that the driver observe the specified tire pressure values
for the tires and the correct pressu res for
the funct ion of the tire pressure mon itor
ing system*.
- Always inflate t ires to the recommended
and correct tire pressure before driving
off.
- Driv ing with under inflated tires bend
more, letting them get too hot resu lting
in tread separation, sudden t ire fa il u re
and loss o f control.
- Excessive speed and/ove rloading can
cause heat bui ld-up, sudden tire fail ure
and loss o f control.
- If the t ire pressure is too low or too high,
the tires w ill wear prematurely and the
vehicle will not hand le we ll.
- If the t ire is no t flat and you do not have
to change a wheel immediate ly, drive at
reduced speed to the nearest service sta
tio n to check the tire pressure and add
air as required.
(D Note
Dr iving without va lve stem caps ca n cause
damage to the tire va lves. To prevent this,
always make sure that factory installed
valve stem caps on all wheels are secure ly
mounted on the va lve.
@ For the sake of the environment
Underinflated tires will a lso increase the
fue l consumption .
Tires and vehicle load limits
There are limits to the amount of load or
weight that any veh icle 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 on ly lead to loss of vehicle con trol,
b ut can a lso damage important par ts of the
vehicle and can lead to sudden tire failure, in
cluding a blowout and sudden deflation that
can cause the vehicle to crash.

Your safety and that of your passengers also
depends on making sure that load limits are
not exceeded. Vehicle load includes everybody
and everything in and on the veh icle. These
load lim its are technically referred to as the
vehicle's
Gro ss Ve hicle Wei ght R ating
("GVWR") .
The "GVWR" includes the weight of the basic
vehicle, all factory installed accessories, a full
tank of fuel, o il, coolant and other fluids plus
maximum load. The max imum load includes
the number of passengers that the vehicle is
in tended to carry ("seat ing capac ity") with an
assumed we ight of 150 lbs (68 kg) for each
passenger at a designated seating posit ion
and the total weight of any luggage in the ve hicle . If you tow a trai ler, the weight of the
trailer hitch and the tongue weight of the
loaded tra iler must be included as part of the
vehicle load.
The
Gr oss Ax le We ight R ating ("GAWR") is
the maximum load that can be applied at each
of the vehicle's two axles.
The Gross Vehicle Weight Rating and the
Gross Axle Weight Rating are listed on the
safety comp liance sticker label located on the
driver's side B-pillar. Your Audi has 4 seat ing
pos itions, 2 in the front and 2 in the rear for
total seating capacity of 4 . In some vehicles
there are 5 seating pos it ions, 2 in the front
and 3 in the rear for tota l seating capacity of
5. Each seat ing position has a safety belt
~ page 140, Safety belts .
The fact that there is a n upper limit to you r
vehicle's Gross Vehicle Weight Rating means
that the total weig ht of whatever is being car
ried in the vehicle ( includ ing the weight of a
trailer hitch and the tongue weight of the
loaded trai ler) is limited . The more passen
gers in the vehicle or passengers who are
heavier than the standard we ights assumed
mean that less we ight can be carried as lug
gage .
The tire pressure label on your Audi also lists
the maximum combined weight of a ll of the
occupants and luggage or other cargo that ..,.
