It is important that the inflation pressu re is
regularly checked and maintained at recom­
mended levels .

What you can do to avoid tire and rim
damage
Low aspect ratio t ires can be damaged more
easi ly by impact with potho les, curbs, gu llies
or ridges on the road, part icularly if the t ire is
underinflated .
I n o rder to m inim ize the o ccu rrence of impact
damage to the tires of your vehicle, we recom­
mend that you observe the following precau­
tions:
- Always mainta in recommended inflat ion
pressures. Check your tire 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
thro ugh or over such obstacles can damage
your t ires. Impact with a curb may also
cause damage to your tires.
- After any impact, immediately inspect your
t ires or have them inspected by the neares t
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 unde rinflat ion, wh ich could eventu­
ally cause t ire fail ure.
If you be lieve that a
t ire may have been damaged, replace the
tire as soon as possible.
- T hese tires may wea r more quick ly than oth­
ers.
- Please a lso remember that, whi le these t ires
deliver respons ive handling, they may ride
less comfortably and make mo re noise than
other c hoices.
Reduced performance in winter /cold
s eason condition s
All tires are designed for certain pu rposes .
The low aspect ratio, u ltra hig h performance t
ir es or iginally insta lled on yo ur vehicle a re 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 drive under those c ircumstances, you
shou ld equ ip your vehicle w ith all -season or
winter tires, which offer bette r traction unde r
those conditions . We suggest you use the rec­
ommended snow o r all-season t ires specified
for yo ur vehicle , or thei r equivalent .

Tire pressure
monitoring system
ill General notes
E ach tire, including the spare ( if provided),
shou ld be checked monthly wh en co ld and in­
flated to t he inflat io n pressure recommended
by the veh icle man ufact urer on t he veh icle
placard or tire inf lation pressure labe l. (If your
vehicle has tires of a different size than the
size indicated on the vehicle placard or tire in ­
flat ion pressure labe l, you should determine
the proper t ire inflation press ure for those
t i res).
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 tell tale when one or more of your
t ires is s ignificantly 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 ress ure. Driving on a sig nifican tly u n­
der -inflated t ire causes the tire to overhea t
and can lead to tire fa ilure . Under-inflation al­
so reduces fuel eff iciency and tire tread life,
and may affect the vehicle's hand ling and
stopp ing ability.
Please note that the TPMS is not a substit ute
for proper tire maintenance, and it is the driv­
er 's respons ibility to maintain correct tire
pressure, even if under-inflation has not
