2017 AUDI A8 tire pressure

~ 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
sw itch on sport mode ¢page

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 . .,.

Tire Pressure Monitoring
System (AS, S8)
(D General notes
A ppl ies to: AS, 58
Each t ire, including the spare (if provided),
should be checked monthly when cold and inflat­
ed to the inflation pressure recommended by the
veh icle manufact urer on the vehicle placard or
tire inflation pressure label. (If your vehicle has
tires of a different size than the size indicated on
the vehicle placard or tire inflation pressure la­
be l, you should determine the proper tire infla­
tion pressure for those tires).
As an added safety feature, your veh icle has been
equipped with a tire pressure monitoring system
(TPMS) that illuminates a low tire pressure te ll­
tale when one or more of your tires is significant­
ly under-inflated . Accordingly, when the low tire
pressure telltale illuminates, you should stop and
check your tires as soon as possible, and inflate
them to the proper pressure . Driving on a signifi ­
cantly under-inflated tire causes the tire to over­
heat and can lead to tire failure. Under-inflation
also reduces fuel efficiency and tire tread life,
and may affect the vehicle's handling and stop­
ping ability .
Please note that the TPMS is not a substitute for
p roper tire maintenance, and it is the driver's re­
sponsib ility to ma intain correc t tire p ressure,
even if under-inflation has not reached the level
to trigger illumination of the TPMS low tire pres­
sure telltale.
Your veh icle has also bee n eq uipp ed w ith a TPM S
mal function indicator to indicate when the sys­
tem is not operat ing properly. The TPMS mal­
function indicator is combined with the low tire
pressure telltale. When the system detects a
malfunction, the telltale will flash for approxi­
mately one mi nute and then remain cont inuously
illuminated . This sequence will continue upon
Wheels
subsequent vehicle start-ups as long as the mal ­
function exists .
When the malfunction indicator is illuminated ,
the sys tem may not be able to detect or signal
low tire pressure as intended . TPMS malfunctions
may occur for a variety of reasons, including the
i nsta llation of replacement or alternate tires or
whee ls on the vehicle that prevent the TPMS
from functioning properly. Always check the
TPMS malfunction telltale after replac ing one or
more tires or wheels on your vehicle to ensure
that the replacement or a lternate tires and
whee ls allow the TPMS to continue to function
properly.
If the Tire Pressure Monitoring System
indicator appears

Description
App lies to : 58 plus
The tire pressure monitoring system monitors
the pressure in the four tires when driving .
The system uses sensors that measure the tem­
perature and pressure in the tires. The data is
sent from these sensors to the control module by
radio frequency.
The Tire Pressure Monitoring System shows the current pressures and temperatures of the tires
in the Infotainment system
o page 304. It also
compares the current tire pressures with the
stored tire pressures and gives a warning in the
driver information system if the tire pressure is
different from what is stored
o page 304.
The system does not detect if the stored tire
pressures match the recommended tire pres­
sures.
- Every time the tire pressures change, for exam-
ple when the load in the vehicle changes,
- after replacing a tire, or
- if wheels with new wheel sensors are used,
you must store the tire pressures again
opage 305.
A WARNING
--The tire pressure monitoring system assists
the driver in monitoring tire pressures. The
driver is responsible for having the tires in­
flated to the correct pressure.
- Do not change the tire pressure when the
temperature of the tire is high. This could
result in serious damage to the tire and
even cause the tire to burst, increasing the
risk of an accident.
- A tire with low pressure flexes more. This
heats the tire up too much. This could cause
the tread to separate and even cause the
tire to burst, increasing the risk of an acci­
dent.
- The Tire Pressure Monitoring System does
not warn you of damage or defects in the
tire construction that could cause the tire to
burst, for example. Inspect your tires regu­
larly.

@ Tips
- The pressure of the spare tire * is not moni ­
tored.
- If t ires are re pla ced, the sensors/valves do
not need to be removed or rep laced . Ju st re­
placed the valve stem and, if necessary, the
valve and the wheel e lectron ics . If you have
quest ions, see your autho riz ed Aud i dea ler

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. ..,..
