was manufactured . Please see q page 208,
Speed roting (letter code) for a listing of the
speed rat ing letter codes and the maximum
speed at wh ich the t ires can be driven .
The speed rating letter code
( c::> page 199) is
on the side wall of the tire
c::> page 207.
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
pe rsonal 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 fai lure in­
cluding a blowout and sudden deflat ion,
loss of control, crashes and serious per­
sonal injuries. Have worn or damaged tires
rep laced immed iate 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
w hich the winter or other tires installed
on your vehicle are rated.
A WARNING
Always adjust your d riving to the road and
traffic conditions. Neve r let the good ac­
celeration of the wi nte r t ir es and all-whee l
dr ive temp t you in to taking extr a ris ks . A l­
ways remember :
- Whe n bra king , a n a ll-wheel d rive 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.
{® For the sa ke of the env ironment
Use summer tires when weather condi­
tions permit. They are qu ieter, do not wear
as quickly and reduce fuel consumption.
Snow chains
Snow cha ins may be f itted only to the front
whee ls, and only to certain tire sizes . Ask your
autho rized Aud i dealer on which tire sizes
snow c hains ca n be used.
If you are go ing to use snow chains, then you
must install them on the front whee ls at
least.
The snow chains must have low-prof ile links
and must not be t hicker than 0.53 inch
(13.5 mm), includ ing the lock .
Remove whee l center covers and trim discs
before putt ing snow cha ins on your vehicle
c::> Q) . For safety reasons cover caps must then
be fitted over the wheel bolts . These are ava il ­
able from autho rized Aud i dealers .
A WARNING
Using the wrong snow chai ns for your veh i­
cle o r ins ta ll ing them in correct ly can in­
crease the risk o f loss of cont ro l leading to
se rious personal injury.
- Snow chains are available in different
sizes. Always make sure to follow the i n­
structions provided by the snow chain manufacturer .
- When driving with snow cha ins never
d rive faster than the speed permitted for
your specific snow chains.
- Always observe local regulations .
(D Note
-Remove snow chain s before dr iv ing o n
roads not covered with snow to avoid
damaging tires and wearing the snow
chains down unnecessa rily.
- Snow chains, which come in to direc t con­
tact with the whee l rim, can scratch or
damage it . Therefore , make sure that the

or ridges on the road, part icu larly if the tire is
u nderinflated.
I n o rder to m inim ize the o ccurrence of impact
damage to the t ires of your vehicle, we recom­
mend that you observe the following precau ­
tions:
- Always maintain recommended infla tion
pressures. Check your t ire pressure every
2,000 miles (3,000
km) and add air if neces ­
sary .
- Drive carefu lly on roads with potholes, deep
gullies or ridges. The impact from driving
t h rough 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 .
- 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 failure . If you be lieve that a
t ire may have been damaged, replace the
t ir e as soon as possible.
- T hese tires may wea r mo re quick ly than oth­
ers.
- Please a lso remember that, wh ile these t ires
deliver respons ive handling, they may ride
l ess comfortably and make mo re no ise than
other choices.
Reduced performance in winter /co ld
sea son condit ion s
All ti res a re des igned for certa in pu rposes.
The low aspect ratio, ultra high performance
tires originally installed on your vehicle are in­
tended for max imum dry and wet road per­
formance and handling. They are not suitable
for cold, snowy or icy weather condit ions. 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 all-season tires specified
fo r your vehi cle, or their eq uivalent. Refer to
q page 211
for more detailed infor­
mation regarding winter tires.
Tire pressure monitoring system
General notes
Applies to veh icles: w ith tire pressure monitoring system
Each tire, incl uding the spare ( if provided),
sho uld be checked monthly when co ld and in­
flated to the inflation pressure recommended by the veh icle manufacturer on the veh icle
placard or tire inflation pressure label. (If your
vehicle has tires of a different size than the
s ize indicated on the vehicle placard or tire i n­
flat ion p ressure label, you should dete rmine
the p roper t ire infla tion p ress ure fo r th ose
t i res.)
As an added safety feature, your ve hicle has
been equipped with a tire pressure mon itoring
system ( TPM S) tha t illum inates a low ti re
pressure tel ltale when one o r more of your
tires is significant ly under-inflated . Acco rding­
l y, when the low tire pressure telltale 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 un­
der- inflated t ire causes the tire to overheat
and can lead to tire fa ilure . Under-inflat ion al ­
so reduces fuel effic iency and tire tread life ,
and may affect the vehicle 's hand ling and
stopp ing abili ty.
Please note that the TPMS is not a substitute
for proper tire ma intenance, and it is the driv­
er's respons ibility to maintain co rrect tire
pressure, even if under-inflation has not
reached the leve l to tr igger illum inat ion of the
T PMS low tire pressu 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 operating p roperly . Th e
T PMS ma lfunction indicator is combined w ith
t h e low tire pressure te lltale. When the sys­
tem detects a malfunction, the telltale will
flash for approximately one min ute and then ..,_
