2018 AUDI A7 Owners Manual

Ti re rotation
Rotating the tires regularly is rec­
ommended to ensure the tires
wear evenly. To rotate the t ires,
install the tires from the rear axle
on the front axle and vice versa.
This will allow the tires to have
approximately the same length of
service life.
For unidirectional tires , make
sure the tires are installed accord­ i ng to the running direction indi­
cated on the tire sidewall
¢page 241.
Hidden damage
Damage to tires and rims can of­
ten occur in locations that are hidden. Unusual vibrations in the
vehicle or pulling to one side may indicate that there is tire damage.
Reduce your speed immediately.
Check the tires for damage. If no
damage is visible from the out­
side, dr ive slowly and carefully to
the nearest authorized Audi deal­ er or authorized Audi Service Fa­
cility to have the vehicle inspect­
ed.

This can increase the risk of an accident because it has a nega­
tive effect on handling, driving

& WARNING
Always adapt the tire pressure
to your driving style and vehicle
load .
-Overloading can lead to loss of
vehicle control and increase
the risk of an accident. Read and follow the important safe­
ty precautions
in¢ page 218,
Tires and vehicle load limits.
-The tire must flex more if the
tire pressure is too low or if
the vehicle speed or load are
too high . This heats the tire up
too much. This increases the
risk of an accident because it
can cause the tire to burst and
result in loss of vehicle con­
trol.
-Incorrect tire pressure in­ creases tire wear and has a
negative effect on driving and
braking behavior, which in­
creases the risk of an accident.
{tfj) Note
Replace lost valve caps to re­
duce the risk of damage to the
tire valves.
@ For the sake of the environment
Tire pressure that is too low in­
creases fuel consumption.

A WARNING
Please note the important safe ­
ty precautions regarding tire
pressure
¢ page 215 and load
limits¢ page 218.
Tires and vehicle load limits
There are limits to the amount of
load or weight that any vehicle
and any tire can carry. A vehicle
that is overloaded will not handle
well and is more difficult to stop. Overloading can not only lead to loss of vehicle control, but can al ­
so damage important parts of the
vehicle and can lead to sudden
tire failure, including a blowout
and sudden deflat ion that can
cause the vehicle to crash .
Your safety and that of your pas ­
sengers also depends on making
sure that load limits are not ex­
ceeded . Vehicle load inc ludes ev­
erybody and everything in and on
the vehicle. These load limits are
technically referred to as the vehi­
cle's
Gross Vehicle Weight Rat­
ing
("GVWR") .
T he "GVWR" inc ludes the weight
of the basic vehicle, all factory in­
stalled accessories, a full tank of
fuel, oil, coolant and other fluids
2 18
plus maximum load . The maxi­
mum load includes the number of
passengers that the vehicle is in­
tended to carry ("seating capaci­
ty") with an assumed weight of
150 lbs . (68 kg) for each passen­
ger at a designated seating posi­
tion and the total weight of any luggage in the veh icle. If you tow
a trailer, the weight of the trailer
hitch and the tongue weight of
the loaded trailer must be includ­ ed as part of the vehic le load.
The
Gross Axle Weight Rating
("GAWR") is the maximum load
that can be applied at each of the
vehicle's two axles .
The fact that there is an upper limit to your vehicle's Gross Vehi ­
cle Weight Rating means that the
total weight of whatever is being
carried in the vehic le (inc luding
the weight of a trailer h itch and
the tongue weight of the loaded
trailer) is limited . The more pas­
sengers in the vehicle or passen­
gers who are heavier than the
standard weights assumed mean
that less weight can be carried as luggage .

A WAR NING
-
Overloading a vehicle can cause
loss of vehicle contro l, a crash
or other accident, serious per­
sonal injury , and even death .
-Carrying more weight than your vehic le was designed to
carry will p revent the vehicle
from handling properly and increase the risk of the loss of
vehicle control.
-The brakes on a vehicle that has been over loaded may not
be able to stop the veh icle
within a safe dis tance .
-Tires on a vehicle that has been overloaded can fail sud­
d en ly , including a blowout and
sudden deflation, causing loss
of control and a crash .
-Always make su re that the to­
tal load being transported -
includ ing the weight of a trail ­
er hitch and the tongue
we ight of a loaded trailer -
d oes not make t he vehicle
heavier than the vehicle's
Gross Vehicle We ight Rating .

Determining correct load
limit
Use the example below to calcu ­
late the total weight of the pas­
sengers and luggage or other
things that you plan to transport
so that you can make sure that
your vehicle will not be overload­
ed .
Steps for Determining Correct
Load Limit
1 . L ocate the statement " THE
COMB INED W EIGH T OF OCCU­
PANTS AND CARGO S HOU LD
NEVER EXCEED XXX KG OR XXX
L BS" on your vehicle's placard
(tire inflation pressure label)
¢ page 215, fig. 189 .
2. Determine the combined
weight of the driver and pas­
sengers that w ill be riding in
your vehicle .
3 . Subtract the combined weight
of the driver and passengers
from
" XXX " kilog rams or " XXX "
pounds shown on the sticker
¢page 215, fig. 189 .

Wheel bolts and rims
Wheel bolts
Wheel bolts must be clean and loosen/t ighten
easi ly .
Rims
Rims with a bolted rim ring* or w it h bolted whee l
covers " consist of mu ltip le pieces . These compo­
nents were bolted together using specia l bolts

and a spec ia l proced ure. Yo u must not repair or
disassemb le them
i::> &. .
A WARNING
Wheel bo lts that are tightened or repaired in­
correct ly can become loose and resu lt in loss
of vehicle contro l, wh ich increases the risk of
an accident . For the correct tighten ing spec ifi­
cation,
see ¢ page 23 7, After changing a
whe el.
- Always keep the wheel bolts and the
threads in the wheel hub clean and free of
grease .
- Only use wheel bolts tha t fit the rim.
- Always have damaged rims repaired by an
author ized Audi dealer or authorized A udi
Serv ice Facility . Neve r repa ir o r disassemb le
rims you rself, because this increases the risk
of an a cciden t.
Winter tires
Win ter tires significant ly imp rove the veh icle's
handling when dr iv ing in winter conditions. Be­
ca use of their construction (width, compound,
tread patte rn), s ummer ti res provide less trac­
tion on ice and snow.
.,. Use winter tires on a ll four wheels .
.,. Only use winter tires that are app roved for yo ur
vehicle .
.,. Please note that the maximum permitted
speed may be lowe r with winter
tires¢ &. in

ized Aud i dealer or authorized Aud i Serv ice Fa ­
cility can inform yo u about t he maximum per­
m itted speed for your tires .

¢ page 215 .
The effectiveness of wi nter tires is reduced g reat­
l y when t he tread is wo rn down to a depth of
0.157 i n (4 mm). The cha ra cte ris tics of winte r
t ir es a lso decrease g rea tly as the t ire ages , re­
gard less o f th e remaining t read.

a co .... N
" N .... 0 00 \.J ' @ For the sake of the environment
Reinstall summer tires at the appropriate
time, because they provide better handling
when roads are free of snow and ice. Summer
tires cause less road noise, tire wear and fuel
consumption.
(D Tips
You can also use all season tires instead of
winter tires. Please note that in some coun­
tries where winter tires are required, only
winter tires with the
& symbol may be per­
mitted .
Snow chains
Snow chains not only improve the driving in win­
ter road conditions, but also the braking .
.,. Only install snow chains on the front wheels.
This applies also to vehicles with all wheel
drive*.
.,. Check and correct the seating of the snow
chains after driving a few feet, if necessary. Fol­
low the instructions from the manufacturer .
.,. Note the maximum speed of 30 mph (SO km/
h). Note the local regulations.
Use of snow chains is only permitted with certain
rim/tire combinations due to technical reasons.
Check with an authorized Audi dealer or author­ i zed Audi Service Facility to see if you may use
snow chains.
You must remove the snow chains on roads with­
out snow. Otherwise, you could impair driving
ability and damage the tires.
A WARNING
Using incorrect snow chains or installing snow
chains incorrectly can result in loss of vehicle
control, which increases the risk of an acci­
dent.
@ Note
- Snow chains can damage the rims/wheel
covers* if the chains come into direct con­
tact with them . Remove the wheel covers*
first . Use coated snow chains.
Wheels
- Using snow chains that add more than 0.4
inch (10.5 mm) of height can severely dam­
age the wheel housings and other vehicle
components.
- Do not install and use snow chains if there is
a malfunction in the air suspension*, be­
cause the vehicle height will be very low. If
you drive with snow chains anyway, the
wheel housings and other vehicle compo­
nents can be severely damaged .
(D Tips
When using snow chains, it may be useful to
switch on sport mode
c> page 121.
Low-profile tires
Applies to: vehicles with low-profile tires
Compared to other tire/rim combinations, low­
profile tires offer a wider tread surface and a
larger rim diameter with shorter tire sidewalls.
This results in an agile driving style. However, it
may reduce the level of comfort and increase
road noise when driving on roads in poor condi­
tion.
Low-profile tires can become damaged more
quickly than standard tires when driving over
large bumps, potholes, manhole covers and
curbs. Therefore, it is particularly important to
maintain the correct tire pressure
c>page 215.
To reduce the risk of damage to the tires and
rims, drive very carefully on poor roads.
Check your wheels regularly every 2,000 mi
(3,000 km) for damage. For example, check for
bulges/cracks on the tires or deformations/
cracks on the rims.
After a heavy impact or damage, have the tires
and rims inspected or replaced immediately by
an authorized Audi dealer or authorized Audi
Service Facility.
Low-profile tires can wear out faster than stand­
ard tires.
Uniform tire quality grading
-Tread wear
221

Wheels
- Traction AA A B C
- T emperature ABC
Quality grades can be found where appl icable on
the tire side wall between tread shoulder and
maximum section width
~ page 206, fig. 187.
For example: Tread wear 200, Traction AA, Tem ­
perature
A .
All passenger car tires must conform to Federal
Safety Requirements in addition to these grades.
Tread wear
The tread wear grade is a comparative rating
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 tire graded
150 would wear one
and one half (1 1/2) times as well on the govern­
ment course as a tire graded
100.
The relative performance of tires depends upon
the actua l conditions of their use, however, and
may depart significantly from the norm due to
variations in driving habits, service practices and
d ifferences in road characteristics and climate.
Traction
The traction grades, from highest to lowest, are
AA, A, Band
C. T hose grades represent the tire's
abi lity to stop on wet pavement as measured un ­
der controlled conditions on specified govern­ ment test surfaces of asphalt and 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
generation of heat and its ability to d iss ipate
heat when tested under controlled 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 excess ive temperature can lead to sudden
tire
fa ilure ~.&. .
The grade C corresponds to a level of perform ­
ance which a ll passenger car tires must meet un-
222
der the Federal Motor Vehicle Safety Standard
No.
109. Grades Band A represent higher levels
of performance on the laboratory test wheel than
the minimum required by law.
A WARNING -
The tract ion grade assigned to this t ire is
based on straight-ahead braking traction
tests, and does not include acceleration, cor­
nering, hydroplaning or peak traction charac­
teristics .
A WARNING
The temperature grade for this tire is estab­
lished for a tire tha t is properly inflated and
not overloaded. Excessive speed, underinfla­
tion, or excessive loading, either separately or
in combination, can cause heat buildup and
possible tire failure.
A WARNING
-
-
Temperature grades apply to tires that are
proper ly inflated and not over or underinflat­
ed.
Tire pressure monitoring system
ill General notes
Each tire, including the spare (if prov ided),
shou ld be checked monthly when cold and inflat­
ed to the inflation pressure recommended by the
vehicle manufacturer on the vehicle placard or
tire inflation pressure label. (If your veh icle has
t ir es of a diffe rent size t han the size ind icated on
the vehicl e placard or tire infl ation press ure la ­
bel, you sho uld determine the proper tire infla­
tion pressure for those tires).
As an added safety featu re, you r vehicle has been
equipped with a tire pressure monitoring system
(TPMS) that illuminates a low tire pressure tell ­
ta le when one or more of your tires is significant­
l y under-inflated. According ly, w hen the low tire
pressure telltale illuminates, you should stop and
check your t ires as soon as possible, and inflate
them to the proper pressure. Dr iving on a
