2017 AUDI A8 service

~ Check and correc t the seating of the snow
chains after driving a few feet , if necessary . Fo l­
l ow the instructions from the manufacturer .
~ Note the maximum speed of 30 mph (SO km/
h). Note the loca l regulat ions.
Use of snow chains is on ly pe rmitted with certain
rim/tire combinations due to technical reasons.
Check w ith an authori zed Audi dealer or author­
ized Audi Service Fac ility to see if you may use
snow chains .
You must remove the snow chains on roads with­
out snow. Otherw ise, you could impair dr iving
ab ility and damage the tires.
_8 WARNING
Using incorrect snow chains o r insta lling snow
chains incorrectly can result in loss of vehicle
cont rol, which inc reases the risk of an acc i­
dent.
(D Note
- Snow cha ins can damage the rims/wheel
covers* if the cha ins come into d irect con·
tact with t hem . Remove the whee l cove rs*
f irst. Use coate d snow chai ns.
- Using snow cha ins tha t add more than 0.4
i nch (10.5 mm) of he igh t ca n seve rely dam­
age the wheel ho usings and other vehicle
componen ts .
- Do no t install and use s now chai ns if there is
a mal funct ion in the adaptive air suspe n­
s ion, because the vehicle heigh t will be very
l ow . If you drive with snow chains anyway,
the wheel ho usings and other vehicle com­
ponents can be severely damaged.
@ Tips
When using snow chains, it may be useful to

Low aspect ratio tires
Your Aud i is factory-equipped with low aspect ra-
o tio tires. These t ires have been thorough ly tested co
~ and been selected specifically for your model for ,.....
~ their supe rb performance, road feel and handli ng 0 0 :c ' Wh eel s
under a var iety o f dr iv ing condit ions . Ask your au ­
thorized Audi dea le r for more detai ls.
T he low aspect rat io of t hese tires is indicated by
a nu meral o f
55 or less in the tire's si ze des igna­
tion . The n umera l represents the ratio of the
tire's sidewa ll height in relation to its tread width
expressed in percentage . Conve ntiona l tires have
a height/width ratio of 60 or more .
The performance of low-aspect- ratio tires is par­
ti cula rly sen siti ve to imprope r inflation p res­
sure. It is the refore important that low aspect
rat io tires are inflated to the specified pressure
and that the inflation pressure is regularly
checked and maintained . Tire pressures should
be checked at lea st once a month and always
before a long trip
¢ page 293 .
What you can do to avo id tire and rim
damage
Low aspect ratio tires can be damaged more eas i­
ly by impact w ith potho les, curbs, gullies or
ridges on the road, particularly if the tire is un­
der inflated .
In order to m in imize the occurrence of impact
damage to t he tires of yo ur vehicle , we recom­
me nd tha t you observe the following preca u­
tio ns:
- Always maintain recommended inflat ion pres­
sures. Check you r ti re pressu re every 2,000
m iles (3,000 km) a nd add air if necessary.
- Dr ive carefully on roads w it h potholes, deep
gullies o r ridges. The impact from dr iving
t hrough or over such obst acles can damage
your tires. Impac t with a cur b may also ca use
damage to your tires.
- After a ny impac t, im med iate ly inspect yo ur
t ires or have them inspe cted by the neares t au­
t horized A udi dealer. Replace a damaged tire as
soon as possible.
- I nspect your tires every 2,000 m iles (3,000 km)
for damage and wear. Damage is not a lways
easy to see. Damage can lead to loss of air and
underinflation, wh ich could event ually cause
tire fa ilure . If you believe that a tire may have
been damaged, replace the tire as soon as pos­
sible .
- These tires may wear more quickly than others . .,.

Wheels
- Please a lso remember that, wh ile these tires
deliver responsive handling, they may ride less
comfortably and ma ke more noise than other
cho ices.
Reduc ed performance in winter /cold s eason
condit ions
All tires are designed for certain purposes. The
low aspect ratio, ultra high performance t ires
or iginally i nstalled on your vehicle are intended
for maximum dry and wet road performance and
handling . They are not s uitable for cold, snowy or
icy weathe r cond itions.
If you drive under those
circumstances, you s hou ld equ ip your ve hicle
with a ll-season or win ter tires, wh ic h offe r bette r
traction under those con dit ions . We suggest you
use the recommended snow or all -season tires
specified fo r your vehicle, or their equivalent.
Refer to¢
page 298 for more deta iled info rm a­
tion regarding w in ter tires.
Uniform tire quality grading
- Tread wear
- Traction AA A B C
- Temperatu re ABC
Qua lity grades can be found where applicable on
the t ire side wall betwee n tread s hou lde r and
maximum sect io n w id th
¢pag e 283, fig. 265.
For e xample: Tread wear 2 00 , Traction AA , Tem­
perature
A .
All passenger car tires must conform to Federa l
Safety Requirements in addition to these grades.
Tread wea r
The tread wear grade is a comparat ive ra ting
based on the wear rate of the tire when tested
under contro lled conditions on a specified gov­
ernment test course.
F or examp le, a t ire graded
150 would wear one
and one ha lf
( 1 1/2) times as well on the govern ­
ment course as a tire g raded
100 .
The rela tive perfo rmance of tires depe nds upon
the actua l condi tions of their use, howeve r, and
may depart significant ly from the norm d ue to
300
variations in driving habits, service p ract ices an d
differences in road characteristics and climate.
Traction
The traction grades, from hig hest to lowest, a re
AA, A, B and
C. Those grades rep resent the tire's
ability to stop o n wet p avement as measure d un­
der controlled conditions on specified govern ­
ment test s urfaces of asphalt an d concrete. A tire
marked C may have poor traction performance
¢ _& .
Temperature
The temperature grades are A ( the highest), B,
and C, representing the tire 's resistance to the
generatio n of heat and its ability to dissipate
heat when tested under contro lled conditions on
a specified indoor laboratory test wheel.
Sustained high temperature can cause the mate­
rial of the tire to degenerate and reduce tire life,
and excessive temperature can lead to s udden
tire failure¢ &.
The grade C cor responds to a level of perform ­
ance which all passenger car tires must meet un­
der the Federal Motor Vehicle Safety Standard
No.
109. Grades Band A represent hig her levels
of performance on the laboratory test wheel than
t h e m inim um requ ired by law .
A WARNING
-
The tract io n grade assigned to this t ire is
based on st raig ht-a head b raking tr action
tes ts, and do es not in clude acceler ation, cor­
nerin g, hyd roplaning or pe ak traction ch arac­

A WARNING
T he temperat ure grade fo r thi s tire is esta b­
lishe d for a tire that is properly inflated and
not ove rloaded. Excessive speed, underinfla -

Care and cleaning
Care and cleaning
General information
Regular, proper care helps to maintain your vehi­
cle's value.
It can also be a requirement when
submitting warranty claims for corrosion damage
and paint defects on the body.
The necessary care products can be obtained
from an authorized Audi dealer or authorized
Audi Service Facility. Read and follow the instruc­
tions for use on the packaging.
A WARNING
-Using cleaning and care products incorrectly
can be dangerous to your health .
- Always store cleaning and care products out
of reach of children to reduce the risk of poi­
soning.
@ For the sake of the environment
- Preferably purchase environmentally-friend­ ly cleaning products.
- Do not dispose 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 ve­ hicle, the more the surface can be damaged. High
temperatures such as those caused by sunlight
increase the damaging effect .
Before washing, rinse off heavy deposits with
plenty of water.
Stubborn deposits such as bird droppings or tree
sap are best removed with plenty of water and a microfiber cloth.
Also, wash the underside of your vehicle once road salt stops being used for the season .
Pressure washers
When washing your veh icle w ith a pressure wash ­
er, always follow the operating instructions pro­
vided with the pressure washer. This is especially
important in regard to the pressure and spraying
distance. Do not aim the spray directly at the
306
seals on the side windows, doors, lids or the sun­
roof* or at tires, rubber hoses, insulating materi­
al, sensors* or camera lenses* . Keep a distance of
at least 16 in (40 cm).
Do not remove snow and ice with a pressure
washer.
Never use cone nozzles or high pressure nozzles.
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 . Follow instruc­
tions from the car wash operator, especially if
there are accessories attached to your vehicle.
If possible, use car washes that do not have
brushes.
Only use car washes where the veh icle remains
stationary and the washing equipment moves
around the vehicle when washing and drying. Car
washes that move the vehicle through the car
wash using a chain are not recommended.
Washing by hand
Clean the vehicle starting from the top and work­
ing 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 vehi­
cle. Insects, grease spots and fingerprints 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 micro­
fiber cloth .
Rinse the vehicle thoroughly again and let it air
dry. Remove any water residue using a chamois. ..,..

wash operator to reduce the risk of acci­
dents.
- To reduce the risk of cuts, protect yourself
from sharp metal components when wash­
ing the underbody or the inside of the wheel
housings.
-After washing the vehicle, the braking effect
may be delayed due to moisture on the
brake rotors or ice in the winter . This in­
creases the risk of an accident . The brakes
must be dried first with a few careful brake
applications.
(D Note
- If you wash the vehicle in an automatic car
wash, you must fold the exterior mirrors in
to reduce the risk of damage to the mirrors.

do not use insect removing sponges, kitchen
sponges or similar items.
- Matte finish painted vehicle components:
- To reduce the risk of damage to the sur-
face, do not use polishing agents or hard
wax.
- Never use protective wax. It can destroy
the matte finish effect .
- Do not place any stickers or magnetic
signs on vehicle parts painted with matte
finish paint . The paint could be damaged
when the stickers or magnets are re­
moved.
