or ridges on the road, part icu larly if the tire is
underinflated.
I n o rder to minim ize the o ccurrence of 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 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 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 ir e as soon as possible .
- Inspect your tires 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 ir e 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, whi le these t ires
deliver respons ive handling, they may ride
less comfortably and make mo re no ise than
other choices.
Reduced performance in winter/cold
season conditions
All tires are designed for certain purposes.
The low aspect ratio, ultra high performance
tires originally installed on your vehicle 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 drive 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
for your vehicle, or their equivalent. Refer
to
q page 263 for more detailed infor­
mation regarding winter tires.
Tire pressure monitoring system
ill General notes
Applies to veh icles: w ith tire pressure monitoring system
Each tire, including 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 vehicle
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 in­
flation pressure label, you should determine
the proper tire inflation pressu re fo r those
t i res).
As an added safety feature, your ve hicle has
been equipped with a tire pressure mon itoring
system ( TPMS) that illuminates a low tire
pressure telltale when one or more of your
tires is significant ly under-inflated. According­
l y, when the low tire pressure telltale i llumi­
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 t ire causes the tire to overheat
and can lead to tire fa ilure . Under-inflation al ­
so reduces fuel efficiency and tire tread life,
and may affect the vehicle 's handling and
stopping ability.
Please note that the TPMS is not a substitute
for proper tire ma intenance, and it is the driv­
er's responsibility to maintain co rrect tire
pressure, even if under-inflation has not
reached the level to trigger illuminat ion of the
TPMS low tire pressu re tellta le .
Your vehicle has also been equipped with a
TPM S ma lfunction indicator to ind icat e when
the system is not operating properly. The
T PMS ma lfunction indicator is combined with
the low tire pressure telltale. When the sys­
tem detects a malfunction, the telltale will
flash for approximately one minute and then ..,_
