In o rder to minimize the occu rrence o f 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 a ir 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 poss ible .
- In spect 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 rinflation, wh ic h could eventu­
ally cause t ire fail ure.
If yo u be lieve that a
tire may have been damaged , replace the
tire as soon as possible.
- These tires may wear more qui ck ly than oth ­
ers.
- Please a lso remembe r that, whi le these t ires
deliver respons ive handling, they may ride
less comfortably and make more noise than
other choices.
Reduced p erformance in winter /cold
sea son condit ion s
All tires are designed for certain purposes .
The low aspect ratio, ultra hig h performance
tires originally installed on your vehicle are in­
tended for max imum dry and wet road per­
f ormance and handling . They are not suitable
for cold, snowy or icy weather cond it 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 io ns . We suggest you use the rec­
ommended snow or all -season tires specified
for your ve hicle, or their equiva 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 manufac turer 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 io n pressu re labe l, you shou ld dete rm ine
the p roper t ire inflation p ress ure fo r those
t i r es).
As an added safety feature , your veh icle has
been equipped with a tire pressure mon ito ring
system ( TPMS) that illum inates a low ti re
pressure te lltale when one or more o f your
t ires is significant ly under -inflated . Acco rding ­
l y, when the low tire pressure te lltale 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 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 affe ct the vehicle's hand ling and
stopp ing ability.
Please note that the TPMS is not a substitute
fo r 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
rea ched the leve l to tr igger illuminat ion of the
TPMS low tire p ressure tellta le .
You r vehicle has also been equipped with a
T PMS ma lfunction indicator to ind icate when
the sys tem is not operating properly . T he
TPMS 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 min ute and then
rema in continuously illum inated . Th is se­
quence will continue upon subsequent vehicle
start-ups as long as the malfunct io n exists.
When the malfunction indicator is illum inat-
ed, the system may not be ab le to detect or

signal low tire pressure as intended. TPMS
malfunctions may occur for a variety of rea­
sons, includ ing the installat ion of replace­
ment or a lternate tires or whee ls on the veh i­
cle that prevent the TPMS from funct ioning
properly . Always check the TPMS malfunct ion
telltale after replacing one or more t ires or
wheels on your veh icle to ensure that the re­
p lacement or a lternate tires and wheels allow
the TPMS to continue to function properly.
If the Tire Pressure Monitoring System
indicator appears
Applies to vehicles: with tire pressure monitoring system
The tire pressure indicator in the instrument
cluster informs you if the tire pressure is too
low or if there is a system malfunction.
F ig. 161 Ins trumen t cluste r: ind icato r light w it h m es­
s age
Using the ABS sensors, the tire pressure moni­
toring system compa res the tire tread circum­
ference and vibration characteristics of the in­
dividual tires .
If the pressure changes in one
or more tires, th is is indicated in the instru­
ment cluster display with an indicator light
IE and a message ¢ fig. 161 . If only one t ire
is affected, the location of that t ire will be in­
d icated. The message turns off after a few mi­
nutes. You can disp lay the message again
¢ page 28.
The tire pressures must be stored in the menu
d isplay aga in each time the pressures change
(switching between part ia l and full load pres­
sure) or after chang ing or replac ing a tire on
your ve hicle ¢
page 245. The tire pressure
monitoring system on ly monitors the ti re
press ure you have stored . You can find the rec­
ommended tire pressures for your vehicle on the
labe l on the driver's doo r pillar
¢ page 229 .
Tire tread circumference and vib ration charac­
teristics can change and cause a tire pressure
warning if:
- I f the tire pressure in one or more ti res is
t oo low.
- The tire has structural damage.
- The tire was replaced or the t ire pressure
changed and it was not stored again

-The spare tire is installed .

Check the tires and replace or repair if neces­

A WARNING
--- If the tire pressure ind icator appears in
the instrument cluster display , one or
mo re of your t ires is sign ifi cant ly unde r­
i n flated. Reduce yo ur speed immedi ately

maneuvers. Stop as soon as possib le and
check the tires and their pressures. In­
f late the tire pressure to the proper pres­
sure as indicated on the vehicle's tire
