or ridges on the road, particularly if the tire is underinflated .
I n o rder to m inim ize the occu rrence of impact
damage to the t ires of your veh icle, we recom ­
mend that you observe the following precau­
tions:
- Always maintain recommended inflat ion
pressures. Chec k 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
through or over such obstacles can damage
your tires. Impact with a curb may a lso
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 tire failure. If you be lieve that a
t ir e may have been damaged, replace the
t ire as soon as possible.
- T hese tires may wea r mo re qui ck ly than ot h­
ers.
- Please a lso remember that, whi le these tires
deliver respons ive handling, they may ride
l ess comfortably and make mo re noise than
othe r choices.
Reduced performance in winter /cold
season condition s
All tires are des igned for certa in pu rposes.
The low aspect ratio, ultra high performance
tires originally 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 condit ions.
If
you dr ive under those circumstances, you
should equip your veh icle with all-season or
winter t ires, which offer better traction under
those cond itions. We suggest you use the rec­
ommended snow or all-season tires specified
for your ve hicl e, or their equ iva lent.

Tire pressure
monitoring system
ill General notes
Each tire, incl uding the spare ( if provided),
shou ld 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 inf lation pressure label. (If your
vehicle has tires of a different size than the s ize indicated on the vehicle placard or tire in­
flat io n pressure labe l, you shou ld determ ine
t h e p rope r tir e inflation p ressu re fo r those
ti res).
As an added safety feature, your veh icle has
been equipped with a tire pressure mon itoring
system ( TPMS) that illum inates a low t ire
pressure te lltale whe n one or more o f you r
tires is significant ly under-inflated . According­
ly, when the low tire pressure te lltale illumi­
nates, you should 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 tire 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 affect 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 driv­
er's respons ibility 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 pressu re tellta le .
Your vehicle has also been equipped with a
T PMS ma lfu nction ind icator to ind icate when
the sys tem is not operating properly. The
T PMS ma lfunction indicator is combined with
the low tire pressure te lltale. When the sys ­
tem detects a malfunction, the telltale will
flash for approximate ly one minute and then ..,.
