2015 AUDI S7 winter tires

268 Tires and wheels
loss of control, crashes and serious per­
sonal injuries. Have worn or damaged tires
replaced immediately.
- Winter tires have maximum speed rating
that may be lower than your vehicle'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-wheel
drive tempt you into taking extra risks. Al­
ways remember:
- When braking, an all-wheel drive vehicle
handles in the same way as a front drive
vehicle .
- Drive carefully and reduce your speed on
icy and slippery roads, even winter tires
cannot help under black ice conditions.
@) For the sake of the environment
Use summer tires when weather condi­
tions permit. They are quieter, do not wear
as quickly and reduce fuel consumption.
Snow chains
Snow chains may be fitted only to the front
wheels, and only to certain tire sizes. Ask your
authorized Audi dealer on which tire sizes
snow chains can be used .
If you are going to use snow chains, then you
must install them on the front wheels at
least.
The snow chains must have low-profile links
and must not be thicker than 0.4 inch (10,5 mm), including the lock.
Remove wheel center covers and trim discs
before putting snow chains on your vehicle
q 0 . For safety reasons cover caps must then
be fitted over the wheel bolts. These are avail­
able from authorized Audi dealers.
A WARNING
Using the wrong snow chains for your vehi­
cle or installing them incorrectly can in­
crease the risk of loss of control 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 specific snow chains.
- Always observe local regulations.
@ Note
-Remove snow chains before driving 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 wheel rim, can scratch or damage it. Therefore, make sure that the
snow chains are suitably covered. Check
the position of the snow chains after
driving a few yards and correct if neces­
sary. Follow the instructions from the
snow chain manufacturer when doing so.
- If the Adaptive Air Suspension* should
malfunction, do not mount or use snow
chains because the vehicle will be ex­
tremely low. If you do drive with snow
chains on while the vehicle is at this lev­
el, the snow chains might severely dam­
age the wheelhouse and other parts of
the vehicle.
(j) Tips
Where snow chains are mandatory on cer­
tain roads, this normally also applies to
vehicles with all-wheel drive .

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 Audi dealer. Rep lace a damaged
t ire as soon as possible.
- Inspect 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 ich could eventu­
ally cause t ire failu re. If you bel ieve that a
t ire may have been damaged, replace the
t ire as soon as possible.
- These tires may wear more quickly than oth­
ers.
- Please also remember that, while these t ires
deliver respons ive handling, they may ride
less comfortably and make mo re no ise than
othe r cho ices .
Reduced performance in winter /co ld
season condition s
All tires are des igned for certain pu rposes.
The low aspect ratio, ultra high pe rformance
tires orig inally installed on your veh icle are in­
tended for maximum dry and wet road per­
formance and handling. They are not suitable for cold, snowy or icy weather conditions. If
you dr ive under those circumstances, you
should equip your vehicle with all-season or
winter tires, which offer better traction under
those cond it ions. We suggest you use the rec­
ommended snow or a ll-season tires specified
for your vehi cle, or their equ ivalent.
Refer to¢
page 267 for more deta iled infor­
mat ion regarding winter tires.
Tire pressure
monitoring system
U) General notes
Each t ire, includ ing the spare (if provided),
should be checked monthly when cold and in­
flated to the inflation pressure recommended by the vehicle manufacture r on the vehicle
p lacard or tire inflation pressure label. (If your vehicle has tires of a diffe
rent size than the
size indicated on the vehicle placard or tire in­
flat ion pressure labe l, you shou ld determ ine
the proper t ire inflation pressure for those
t ires).
As an added safety feature, your ve hicle has
been equipped with a tire pressure monitoring
system (TPMS) that illum inates a low tire
pressure telltale when one or more of your
t ires is significantly under-inflated. According­
ly, when the low tire pressure telltale illumi­
nates, you shou ld stop and check you r tires as
soon as possib le, and inflate them to the
proper p ressu re. Driving on a sig nifican tly u n­
der- inflated t ire causes the tire to overheat
and can lead to tire fai lure . Under-inflation al­
so reduces fuel efficiency and tire tread life,
and may affect the vehicle 's hand ling and
stopp ing ability.
Please note that the TPMS is not a substitute
for proper tire maintenance, and it is the driv­ er's respons ibility to maintain correct tire
pressure, even if under-inflation has not
reached the level to trigger illumination of the
TPMS low tire pressure telltale .
Your vehicle has also been equipped with a
TPMS malfunction indicator to ind icate when
the system is not operating properly. The
TPMS ma lfunction indicator is combined w ith
the low tire pressure telltale . When the sys­
tem detects a malfunction, the telltale will
flash fo r approxima te ly one m inute and then
rema in continuously illum ina ted. This se­
quence will continue upon subsequent vehicle
start-ups as long as the malfunction exists.
When the malfunction indica to r is illum inat­
ed, the system m ay not be ab le to detect or
signal low tire pressure as intended . TPMS
malfunctions may occur for a var iety of rea­
sons, incl uding the insta llation of replace­
ment or alternate tires or wheels on the vehi­
cle that prevent the TPMS from functioning
properly. Always check the TPMS malfunction
telltale after replacing one or more tires or
whee ls on you r vehicle to ensu re that the re­
placement o r alternate ti res and wheels a llow
the TPM S to cont inue to func tion p roperly.

272 Tires and wheels -Under certain conditions (such as a spor­
ty driving style, winter conditions or un­
paved roads), the pressure monitor
indicator may be delayed.
- Ask your authorized Audi dealer if run­
flat tires may be used on your vehicle.
- The tire pressure monitoring system may
stop working when there is an ESC mal­
function.
- 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
c:> page 260. We recom­
mend using these tires.
Reset tire pressure monitoring system
If the tire pressure is adjusted, wheels are ro­
tated or changed, the TPMS must be reset via
MMI.
• Before storing the new tire pressures, check
that the current pressures on all four tires correspond to the specified values and
adapt the pressures to the current load <=>page 247.
• Switch on the ignition.
• Select in the MMI: !CAR !function button>
(Car)* systems control button > Servicing &
checks > Tire pressure monitoring > Store
tire pressures> Yes, store now.
Do not store the tire pressure if there are
snow chains on the tire. Otherwise, a sys­
tem malfunction may occur.
