2013 AUDI A4 SEDAN snow chains

_& WARNING
-Sensors have dead spaces in which ob­
jects cannot be detected. Be especially
alert for small children and animals,
since they are not always detected by the
sensors.
- The acoustic park ing system is not a sub­
st itute for the driver 's own caution and
alertness. Ultimate responsibi lity always
remains with the driver during parking
and simi lar maneuvers . Always watch
where you are driving.
- You should always adjust the volume and
frequency of the warning tones so that
yo u can easily hear the acoustic distance
warning even if the radio is p laying, the
air-cond itioner blower is on High or there
is a high level of outside noise .
- Check the settings whenever anyone
else has driven the vehicle before you.
(D Note
-Remember that low obstacles for which
a warn ing has already been issued may
"dive" below the system's sensing zone if
the vehicle is being backed up closer. In
this case, the warning sound shutting off
does
not in dicate that you have cleared
the obstacle . Instead, impact is immi­
nent.
- Objects such as trailer hitches, chains,
narrow posts or fences covered by a th in
l ayer of paint may not always be detect­
ed by the system. They can still damage
your vehicle without warning .
@ Tips
Keep the sensors in the rear bumper clean
and free of snow and ice so that the acous­
tic parking assist system can function
properly.

a ccident!
(D Note
- Low obstacles a lready s ignaled by a
wa rning can disappear from th e system's
detec tion range as they are approa ched
and w ill not con tinue to be signaled. Ob­
jec ts such as barr ier chains, tr ailer draw
bars, thin painted vertica l poles or fen ­
ces may not be detecte d by the system,
posing risk of damage.
- In the MMI display, t he direction of trav­
el of the vehicle rear is represented de ­
pending on the steering wheel angle.
The ve hicle fro nt swings out more tha n
the vehicle rear . Maintain plenty of d is­
tance from an obstacle so that your out­ side mirror o r a corner of you r vehicle

ger of accident!

186 Intelligent technology
-Always accelerate with special care on
even, smooth surfaces such as those that
are wet or covered with ice and snow.
The drive wheels can spin even with
these assistance systems that cannot al­
ways help to reduce the risk of loss of ve­ hicle control.
(i_) Tips
- ABS and ASR only work correctly when
all four wheels are equipped with identi­
cal tires . Different tire sizes can lead to a
reduction in engine power.
- You may hear noises when the systems
described are working .
- If the indicator light

Winter tires
When dr iving in t he winter, yo ur vehicle wi th
a ll -wheel drive h as an adv ant age, even w it h
regular tires. In wi nter road conditions it may
be advisable to mount winter tires (or all -sea ­
son tires) for improved driveability and brak­
ing : these tires must be mounted on
all fou r
wheels .
See also c::> page 245, Winter tires.
Tire chains
Where tire chains a re mandatory on certain
roads, this no rma lly also app lies to veh icles
with all-wheel drive
c::> page 246 , Snow
chains .
Replacing wheels /tires
Vehicles wi th a ll-wheel drive must alw ays
have tires of the same s ize. A lso avoid tires
with different tread depths . For detai ls see
page
c::> page 241, New tires and replacing
tires and wheels.
Off-Road driving?
Your A udi does no t have enough g ro und cle ar­
ance to be used as an off -road vehi cle. It is
therefore best to avoi d rough tracks and un­
even te rrain as much as possib le . Also refer to
c::> page 192.
A WARNING
A lways ad just yo ur dr iv ing to road and traf­
fic conditions. Do not let the extra safety
afforded by all-wheel drive tempt you into
taking extra risks .
-Al tho ugh t he all-wheel driv e is ve ry ef­
fective, always remember that braking
capacity is lim ited by tire t raction. You
should t herefore not d rive a t excessive
speeds on i cy or slippery ro ad s urfa ces.
- On wet road surfa ces, be careful not to
d rive too fast bec ause the fron t whee ls
co uld begin to slide on top of the water
(aquaplani ng) . If th is should occur, yo u •

was manufactured . Please see q page 242,
Speed roting (letter code) for a listing of the
speed rat ing letter codes and the maximum
speed at which the tires can be driven .
The speed rating letter code( ¢
page 232) is
on the side wall of the tire
c::> page 241.
A WARNING
Winter tires have maximum speed limits
that may be lower than your vehicle's max­
imum speed . Always know the maximum
speed before driving off . Never drive faster
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 inj ury to you and your passen­
gers.
A WARNING
=
Driving faster than the maximum speed
for which the winter tires on your vehicle
were designed can cause tire failure in­
cluding a blowout and sudden deflation,
loss of control, crashes and serious per­
sonal injuries. Have worn or damaged tires
replaced immed iately .
- 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 is ks . A l­
ways remember :
- When brak ing , an a ll whee l drive vehicle
hand les in the same way as a front drive
vehicle.
- Drive caref ully and reduce your speed on
icy and slippery roads, even winter tires
cannot he lp under black ice conditions.
{® Fo r the s ake of the en vironment
Use summer tires when weather condi­
tions permit. They are quieter, do not wear
as quickly and reduce fuel consumption.
Snow chains
Snow cha ins may be f itted only to the front
wheels, and only to certain tire sizes . Ask your
authorized Aud i dealer on which tire sizes
snow chains can be used.
The snow chains must have low-prof ile links
and must not be th icker than 0.53 inch
(13 .5 mm), includ ing the lock .
Remove wheel center covers and trim discs
before putt ing snow chains on your vehicle
c::> @ . For safety reasons cover caps must then
be fitted over the wheel bolts . These are avail­
able from autho rized Aud i dealers.
A WARNING
Using the wrong snow chai ns for your veh i­
cle or instal ling them incorrect ly can in­
crease the risk of loss of cont ro l leading to
serious personal injury.
- Snow chains are available in different
sizes . Always make sure to follow the in­
structions provided by the snow chain manufacturer.
- When driving with snow chains never
drive faster than the speed permitted for
your specif ic 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 unnecessarily.
- Snow chains, which come into direct con ­
tact with the whee l rim, can scratch or
damage it . Therefore, make sure that the
snow chains are s uitably covered. Check
the pos ition of the snow chains after

driving a few yards and correct if neces­
sary . Follow the instructions from the
snow cha in manufacturer when doing so.
(D Tips
Where snow chains are mandatory oncer ­
tain roads, this norma lly also applies to
veh icles with all wheel drive.
Wheel bolts
Wheel bolts must always be tightened to the
correct torque.
The design o f whee l bolts is matched to the
factory insta lled r ims . If different rims are fit ­
ted, the correct wheel bo lts wit h the right
l ength 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 bo lts from a different vehicle -even if it
is the same model
<=> page 274.
A WARNING
Improperly tightened or maintained wheel
bolts can become loose caus ing loss of
cont ro l, a co llision and serious persona l in­
Jury .
- Always keep the w heel bolts and the
threads in the wheel hubs clea n so the
w hee l bolts can t urn easily and be p rop­
erly t igh tened.
- Never grease or oil the wheel bolts and
the threads in the wheel h ubs. They can
become loose wh ile d riving if greased or
oiled, even if tightened to the specified
torq ue.
- Only use whee l bo lts that belong to the
rim being installed .
- Never use different whee ls bolts on your
vehicle.
- Alw ays m ain ta in the co rrec t tig hten ing
torq ue fo r the wheel bo lts to reduce the
risk of a wheel loss . If the tightening tor­
que of the wheel bo lts is too low, they
can loosen and come out when the vehi-
Tire s an d wheel s 24 7
cle is mov ing. If the tightening torq ue is
too high, the wheel bolts and threads
can be damaged and the whee l can be­
come loose.
@ Note
The specified torque for the whee l bolts is
90 ft lbs . (120 Nm) w ith a tolerance of
± 7,4 ft lbs. (± 10 Nm). Torque whee l bolts
diagonally . After changi ng a wheel, the
torque m ust be checked as soon as poss i­
ble with a to rque wrench -preferably by an
a uthorized Aud i dea le r or qualified wor k­
shop.
Low aspect ratio tires
Your A udi is fac tory -eq uipped w ith low aspect
ratio tires . These tires have been tho ro ughly
tested and been se lected specifically for your
model for their superb performance, road fee l
and handling under a variety of driving condi­
tions . Ask your authorized Aud i dealer for
more details.
The low aspect ratio of these t ires is ind icated
by a numeral of
55 or less in the tire's size
designation. The numera l represents the ratio
of the tire's sidewa ll height in relation to its
tread width exp ressed in percentage. Conven­
tiona l tires have a he ight/w idth ratio of 60 or
more.
The performance of low-a spect-r atio tire s is
particularly sensit ive to improper inflation
pre ssure. It is therefor e important that low
a spect ratio tire s are inflated to the specified
pres sure and that th e inflation pr essure i s
regularly checked and maintained. Tire pre s­
sure s should be chec ked at lea st once a
month and always before a long trip
<=> page 236, Checking tire pressure.
What you can do to avo id tire and rim
damage
Low aspect ratio tires can be damaged mo re
easily by impact w ith potholes, curbs, gull ies
or ridges on the road, particularly if the tire is
under inflated . ..,.

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 .
- The driver is responsible for maintaining
the correct tire pressures. You must
check the tire pressures regularly .
- Under certain conditions (such as a spor­
ty driving style, winter conditions or un­ paved roads), the pressure monitor indi ­
cator may be delayed .
-Ask your authorized Audi dealer if run­ flat tires may be used on your vehicle.
Your vehicle registration becomes invalid
if you use these tires when not permit­
ted. Damage to your vehicle or accidents
could also result.
@ Tips
- 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" identification on the
tire sidewall ¢
page 241. We recom­
mend using these tires.
Reset tire pressure monitoring system
Applies to vehicles: with tire pressure monitoring system
If the tire pressure is adjusted, wheels are ro­
tated or changed, the TPMS must be reset via
radio or MMI*.
11> Before resetting the TPMS, the current pres­
sures of all four tires must correspond to
the specified values. Adjust the tire pressure and reset the pressure in the tire pressure
monitoring system according to the load
you are carrying

has been designed specifically fo r you r type of
vehicle . It must not be swapped with a com­
pact spare t ire from another type of veh icle.
Snow cha ins
F or technical rea son s, the use of snow chains
on the compact spare tire is
not p ermitt ed .
If you do have to dr ive with snow cha ins and a
front tire fails, mount the spare whee l w ith
tire instead of a rear t ire. Install the snow
cha ins on the rear tire and use it to rep lace
the defective front tire .
A WARNING
-Never use the spare tire if it is damaged
or if it is worn down to the tread wear in­
dicators.
- If the spare tire is more than 6 years o ld,
use it only in an emergency and w ith ex­
treme caution and careful driving.
- The spare tire is intended only for tem­
porary and short-term use. It should be
replaced as soon as possib le w ith the
normal wheel and tire.
- After mounting the compact spare tire,
the tire pressure must be checked as
soon as poss ible. The tire pressure of the
compact spa re tire must be 4.2 bar; oth­
erw ise, you risk hav ing an accident.
- Do not drive faster than SO mph (80 km/
h). You risk having an acc id ent.
-Avoid full-throttle acce le rat ion, heavy
braking, and fast corner ing . You risk hav­
ing an acc ident.
- Never drive us ing more than one spare
wheel and tire. You risk having an acci­
dent .
- Normal summer or winte r tires must not
be mounted on the compact spare whee l
rim.
- For technical reasons, the use of ti re
c hains on the spare tire is not permitted.
If it is necessa ry to dr ive wi th tire ch ains,
the spare whee l must be mounted on the
front axle in the event o f a f lat in a rear
t ir e. The newly ava ilable front wheel
must then be installed in place of the rear whee
l with the flat tire. Installing
the t ire cha in before mounting the whee l
and tire is recommended.
- Loose items in the passenger compart­
ment can cause serious personal injury
during hard brak ing or in an accident.
Never store the inflatable spare tire or
jack and tools in the passenge r compart­
ment.
