2013 AUDI A7 winter tires

264 Tire s and wheel s
In o rder to minimize the occurrence o f impact
damage to the tires of your vehicle, we recom­ mend that you observe the following precau­
tions :
- Always maintain recommended inflation
pressures. Check your tire pressure every
2,000 miles (3,000 km) and add a ir if neces­
sary.
- Drive carefu lly on roads with potholes, deep
gullies or ridges. The impact from driving
through or over such obstacles can damage
your tires. Impact with a curb may also cause damage to your tires.
- After any impact, immediately inspect your
tires or have them inspected by the nearest
authorized Aud i dealer . Replace a damaged
t ire as soon as possible .
- In spect your t ires every 2,000 miles (3,000
km) for damage and wear . Damage is not al­
ways easy to see. Damage can lead to loss of
air and underinflation, wh ic h could event u­
ally cause t ire fail ure.
If yo u be lieve that a
ti re may have been damaged, replace the
tire as soon as possible.
- These tires may wea r more qui ck ly than oth­
ers.
- Please a lso remembe r that, whi le these t ires
deliver respons ive handling, they may ride
less comfortably and make more noise than
other choices.
R educed p erformance in winter /cold
sea son conditions
A ll tires are designed for certain purposes .
The low aspect ratio, ultra high performance
tires originally installed on your vehicle are in­
tended for max imum dry and wet road per­
f ormance and handling . They are not suitable
for cold, snowy or icy weather cond it ions.
If
you dr ive under those circumstances, you
should equip your vehicle with all-season or
winter tires, whi ch offe r better traction under
those cond it ions . We suggest you use the rec ­
ommended snow or a ll-season tires specifie d
for your vehicle, or their equiva lent .

Tire pressure
monitoring system
ill General notes
Applies to veh icles: w ith tire pressure monito ring system
Each tire, incl uding the spare (if provided),
sho uld be checked monthly when co ld and in ­
flated to the inf lat ion pressure recommended
by the veh icle manufacturer on the veh icle
placard or tire inflation pressure label. (If your
vehicle has tires of a d ifferent size than the
s ize indicated on the vehicle placard o r tire in­
flat io n pressu re label, you sho uld dete rmine
the p roper t ire infla tion p ressure fo r those
t ir es) .
As an added safety featu re, your ve hicle has
been equipped with a tire pressure mon itoring
system ( TPM S) that illum inates a low ti re
pressure te lltale whe n one or more o f you r
tires is signif icant ly under -inflated . Acco rding­
l y, when the low tire pressure te lltale i llumi­
nates, you shou ld stop and check your tires as
soon as possib le, and inflate them to the
proper pressure. Driving on a sign ificantly u n­
der- inflated t ire causes the tire to overheat
and can lead to tire fa ilure . Under -inflation al ­
so reduces fuel eff ic iency and tire tread life,
and may affe ct the vehicle 's hand ling and
stopp ing ability.
Please note that the TPMS is not a substitute
for proper tire ma intenance, and it is the d riv­
er's respo nsibility to maintain co rrect tire
pressure, even if under -inflation has not
reached the leve l to tr igger illuminat ion of the
T PMS low tire p ressu re tellta le .
You r vehicle has also been equipped with a
T PMS ma lf u nction indicator to ind icate when
the sys tem is not oper ating properly . T he
T PMS ma lfunction indicator is comb ined w ith
the low tire pressure te lltale. Whe n the sys­
tem detects a malfunction, the telltale will
flash for approximately one min ute and then
rema in con tinuously i llum inated . T hi s se­
quence will continue upon subsequent vehicle
start-ups as long as t he malfunct ion exists . .,.

26 6 T ire s and whee ls
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.

Do not store the tire pressure if there are
snow cha ins on the tire .
