2013 AUDI A7 snow chains

-If the brake booster is not working, for
example when towing your vehicle, or
because the brake booster has somehow
been damaged, the brake pedal must be
pressed considerably harder to make up
for the lack of booster assistance.

Driving with your
quattro ®
Applies to vehicles : with all-wheel drive
With all-wheel drive, all four wheels are driv­
en .
General info rmation
With all Wheel Drive, power is distributed to
all four wheels. This happens automatically
depending on your driving style and the road
cond it ions at the time . See also ¢
page 196 .
With the sport different ia l*, power dist ribu­
tion to the rear wheels is variable and can be
adjus ted with A udi drive select*
¢ page 102.
Always read and follow safety precautions
¢ ,0. .
Winter tires
When dr iving in the winter, your vehicle with
all-wheel drive has an advantage, even w it h
regular tires. In winter ro ad conditions it may
be advisable to mount winter tires (or all -sea ­
son tires) for improved driveability and brak­
ing: these tires must be mo unted on
all fou r
whee ls.
See also ¢ page 261, Winter tires.
Tire chains
Where tire chains are mandatory on certain
roads, this norma lly also applies to veh icles
with all-wheel drive¢
page 262, Snow
chains.
Replacing wheels /tires
Vehicles with al l-wheel d rive must always
have tires of the same s ize. A lso avoid tires
with different tread depths . For detai ls see
page ¢
page 2 5 7, New tires and replacing
tires and wheels .
Off-Road driving?
You r A ud i does not have enough gro und clea r­
ance to be used as an off-road vehicle .
It is
therefore best to avoid rough tracks and un ­
even terra in as much as possib le . Also refer to

than the speed permitted for your specific
w inter t ires. This will cause damage to the
tires leading to an accident and serious
personal injury to you and your passen­
gers .
A WARNING
Driv ing faster than the maximum speed
for which the w inter t ires on your vehicle
we re designed can cause tire fai lu re in­
cluding a blowout and sudden deflat ion,
loss of control, crashes and serious per­
sonal injuries. Have worn or damaged tires
rep laced immediate ly .
- Winter tires have maximum speed rat ing
that may be lower than your veh icle's
maximum speed.
- Never drive faster than the speed for
which the winter or other tires installed
on your vehicle are rated.
A WARNING
Always adjust your driving to the road and
traffic conditions. Never let the good ac­
celeration of the winter tires and all-whee l
drive tempt you into taking extra r isks. A l­
ways remember :
- When brak ing, an all-w heel drive vehicle
hand les in the same way as a front drive
vehicle .
- Drive carefu lly and reduce your speed on
icy and slippery roads, even winter tires
cannot he lp under black ice condit ions .
@ For the sake of the environment
Use summer tires when weather cond i­
tions permit . They are quieter, do not wea r
as quickly and reduce f ue l consumption .
Snow chains
-
Snow chains may be fitted on ly to the front
wheels, and only to certa in tire sizes. Ask yo ur
author ized Audi dealer on wh ic h tire sizes
snow chains can be used.
If you are going to use snow chains, then you
must i nstall them on the front whee ls at
l east.
T he snow chains mus t have low-p rofile links
and must not be th icker than 0 .4 inch
(10,5 mm) , includ ing the lock .
Remove whee l cen ter covers and t rim discs
before pu tting snow c hains on your veh icle
¢ (D . For safety reasons cover caps m ust then
be fitted over the wheel bo lts. These are avail­
able from autho rized Aud i dealers .
A WARNING
Using the wrong snow chains for your veh i­
cle or installing them incorrect ly can in­
crease the risk of loss of contro l leading to
se rious pe rsonal injury.
- Snow chains are available in different
sizes . Always make sure to follow the in­
structions p rov ided by t he snow chain
manufacturer.
- W hen driving with s now cha ins never
driv e faster than t he speed permitted for
your specifi c snow chains.
- Always observe local regulations.
(D Note
-Remove snow chains before dr iv ing on
roads not covered with snow to avoid
damaging tires and wearing the snow
chains down un necessa rily.
- Snow chains, which come i nto direct con­
t act with the whee l rim, can scratch or
damage it. Therefo re, make sure that the
snow chains are s uitably covered. Check
t he pos ition o f th e snow cha ins afte r
dr iv ing a few yards and correct if ne ces ­
sary. Follow the inst ructions from the
snow chain ma nufactu rer when do ing so .
- If the Adaptive Air Suspens ion * sho uld
ma lf u nction, do not mount or use snow
chains because the vehicle wi ll be ex­
treme ly low. If you do drive with snow
chains on while the vehicle is at this lev­
el, t he snow cha ins might seve rely dam­
age the whee lhouse and o ther parts of
the vehicle.

@ Tips
Where snow chains are mandatory oncer­
tain roads, this normally also applies to
veh icles with all-wheel dr ive.
Wheel bolts
Wheel bolts must always be tightened to the
correct torque .
The design of whee l bolts is matched to the
factory insta lled rims . If different rims are fit­
ted, the correct wheel bolts with the right
length and correctly shaped bolt heads must
be used. This ensures that wheels are f itted
securely and that the brake system functions
correctly .
In certain circumstances, you may not use
wheel bolts from a different vehicle -even if it
is the same model
<=> page 291.
.&_ WARNING
Improperly tightened or maintained wheel
bolts can becom e loose caus ing loss of
cont ro l, a co llision and serious persona l in­
Jury .
- Always keep the wheel bolts and the
threads in the wheel hubs clea n so the
w heel bolts can t urn easily and be prop ­
erly t ightened .
- Never grease or oil the wheel bolts and
the threads in the wheel hubs. They can
become loose while d riving if greased or
oi led, even if tightened to the specif ied
torque.
- Only use whee l bolts that belong to the
rim being installed .
- Never use different whee ls bolts on your
vehicle.
- Always maintain the co rrect tighten ing
torq ue for the wheel bo lts to reduce the
risk of a wheel loss . If the tightening tor­
que of the wheel bolts is too low, they
can loosen and come out when the vehi­
cle is moving. If the tightening torque is
too high, the whee l bolts and threads
Tire s an d wheel s 263
can be damaged and the whee l can be­
come loose.
(D Note
The specified torque for the whee l bolts is
90 ft lb (120 Nm) with a tolerance of± 7,4
ft lb(± 10 Nm) . Torq ue whee l bolts diago­
nally. After changing a whee l, the torq ue
must be checked as soon as possible with a
torque wrench -preferably by an author­
i zed Audi dealer or qualified workshop.
Low aspect ratio tires
You r Aud i is facto ry-equ ipped w it h low aspect
ra tio tires. These tires have been tho ro ughly
tested and been se lec ted spe cifically for you r
model for their superb perfo rmance, road fee l
and handling under a variety of driving condi­
tions. Ask your authorized Audi dealer for
more details .
T he low aspect ratio of these t ires is ind icated
by a numera l of
55 or le ss in the tire's s ize
designation. The numera l represents the ratio
of the t ire's sidewa ll height in relation to its
tread width expressed in percentage. Conven­
tiona l tires have a he ight/w idth rat io of 60 or
more .
The performance of low-aspect -ra tio tire s is
particularly sens it iv e to improper inflation
pressure. It is therefore important that low
aspect ratio t ires are inflated to the specified
pre ssure and that the inflation pressur e is
regularly che cked and maintain ed. Tire pre s­
s ures should be checked at least on ce a
m onth and alwa ys before a long trip
¢ page 2 52, Checking tire pressure .
What you can do to avoid tire and rim
damage
Low aspect ratio tires can be damage d mo re
easily by impact w ith potholes, curbs, g ull ies
or ridges on t he road, partic ularly if the tire is
u nderinflated.

check the tires and their pressures. In­
flate the tire pressure to the proper pres­
sure as indicated on the vehicle's tire
pressure label
c> page 250. Driving on a
significantly under-inflated tire causes
the tire to overheat and can lead to tire
failure. Under-inflation also is likely to impair the vehicle's handling and stop­
ping ability.
- T he driver is responsible for ma inta ining
the correct tire pressures. You must check the t ire pressures regular ly .
- Under certain cond itions (such as a spor­
ty driving style, winter condit ions or un­
paved roads), the pressure monitor indi­
cator may be de layed .
- Ask your author ized Audi dealer if r un­
flat tires may be used on your vehicle .
Your vehicle regist ration becomes invalid
if yo u use these tires when not permit­
ted. Damage to your veh icle or accidents
cou ld also result.
- The tire pressure monitoring system
stops working when there is an ESC/ABS
malfunction .
- Using snow chains may result in a system
malfunction.
- The tire pressure monitoring system on
your Audi was developed using tires with
the "AO" or "RO" identif ication on the
tire sidewall
c> page 257. We recom­
mend using these t ires.
Reset tire pressure monitoring system
App lies to vehicles: with tire pressure monito ring system
If the tire pressure is adjusted, wheels are ro­
tated or changed, the TPMS must be reset via
MMI.
