2010 AUDI A5 CABRIOLET inflation pressure

___ T_ ir_e_ s _ a_ n _ d_ w_ h_e_ e_ ls _______________________________________________ _
After changing a wheel, the torque must be checked as soon as
possible with a torque wrench -preferably by an authorized Audi
dealer or qualified workshop. •
Low aspect ratio tires
Your Audi is factory-equipped with low aspect ratio tires. These tires
have been thoroughly tested and been selected specifically for your
model for their superb performance, road feel and handling under a
variety of driving conditions. Ask your authorized Audi dealer for
more details.
The low aspect ratio of these tires is indicated by a numeral of
55 or
less
in the tire's size designation. The numeral represents the ratio of
the tire's sidewall height in relation to its tread width expressed in
percentage. Conventional tires have a height/width ratio of 60 or
more.
The performance of low-aspect-ratio tires is particularly sensitive to
improper inflation pressure. It is therefore important that low
aspect ratio tires are inflated to the specified pressure and that the
inflation pressure is regularly checked and maintained. Tire pres­
sures should be checked at least once a month and always before a
long trip=>
page 302, "Checking tire pressure" .
What you can do to avoid tire and rim damage
Low aspect ratio tires can be damaged more easily by impact with
potholes, curbs, gullies or ridges on the road, particularly if the tire is
underinflated.
In order to minimize the occurrence of impact damage to the tires of
your vehicle, we recommend 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 necessary.
• Drive carefully 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 Audi dealer. Replace a damaged
tire as soon as possible.
• Inspect your tires every 2,000 miles (3,000 km) for damage and
wear . Damage is not always easy to see. Damage can lead to loss of
air and underinflation, which could eventually cause tire failure. If
you believe that a tire may have been damaged, replace the tire as
soon as possible.
• These tires may wear more quickly than others.
• Please also remember that, while these tires deliver responsive
handling, they may ride less comfortably and make more noise 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
intended for maximum dry and wet road performance and handling.
They are not suitable for cold, snowy or icy weather conditions. If you
drive under those circumstances, you should equip your vehicle with
all-season or winter tires, which offer better traction under those
conditions. We suggest you use the recommended snow or all-season
tires specified for your vehicle, or their equivalent.
Refer to=>
page 311 for more detailed information regarding winter
tires. •

General notes '
Each tire, including the spare (if provided), should be checked
monthly when cold and inflated to the inflation pressure recom­
mended by the vehicle manufacturer on the vehicle placard or tire
inflation pressure label. (If your vehicle has tires of a different size .,

Tires and wheels Ill _______________ _____.
than the size indicated on the vehicle placard or tire inflation pressure
label , you sho uld determine the proper tire infla tion pressure fo r
those tires.)
As an added safety feature, your vehicle has been equipped with a tire pressu re monitoring sys tem (TPMS) that illuminates a low tire pres ­
sure telltale when one o r more of your t ires is s ignificantly under­
inflated. Accord ingly, when the low tire pressure tellta le illumi nates,
you should stop and check your tires as soon as possib le, and inflate
them to the proper p ress ure. D riving on a sign ificantly under-inflated
tire causes the tire to overheat and can lead to tire fa ilure . Under­
inflation also reduces f uel 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 mainte­
nance, and it is the d river's responsibility to mainta in correct tire
pressure, even if under-inflation has not reached the level to trigger
ill umination of the TPMS low tire press ure te lltale.
Your vehicle has also been equipped w ith a TPMS malfunction indi­
cato r to indica te when the system is not operating properly . The
TP MS ma lf u nction indicator is combined with the low tire p ress ure
telltale. When the system detects a malfunct ion, the telltale will
fl ash for approximate ly one minute and then rema in continuously
illuminated. This sequence will continue upon subsequent vehicle
sta rt-ups as long as the malfunction exists.
When the ma lfunction indicator is illum inated, the system may not
be able to de tect or signa l low ti re pressure as intended . TPMS
ma lfunctions may occur fo r a var iety of reaso ns, includ ing the instal­
lation of replacement o r alternate tires or wheels on the vehi cle that
prevent the T PMS from functioning properly . Always check the TPMS
ma lfunction tellta le after replacing one or more tires or whee ls on
yo ur vehicle to ensure that the replacement o r alte rnate t ires and
wheels allow the TPMS to continue to funct ion proper ly .•

Us ing the ABS sensors, the tire pressure monitor ing system compares
the t ire tread c ircumference and vibration characteristics of the ind i­
vidual tires .
If the pressure decreases in one or more tires, this is indi -
cated in the instrument cl uster with a warning symbol and a
message ~ fig. 232 . The d river message in the display goes o ut after
5 seconds . The driver message can be displayed again by p ressing the

& WARNING
• If the tir e pres sure indicator appears in the instrument cluster
display, one or more of your tires i s significantly under-inflated.
Reduce your speed immediately and avoid any hard steering or
braking maneuvers. Stop as soon a s possible and check the tires
and their pressures . Inflate the tire pressure to the proper pres­
sure as indicated on the vehicle 's tire pressure label=>
page 300.
Driving on a significantly under -inflated tire causes the tire to
overheat and can lead to tire failure. Under -inflation also is likely
to impair the vehicle's handling and stopping ability.
& WARNING (co ntinued )
• The driver is re sponsible for maintaining the correct tire pres­
sures . You must check the tire pres sures regularly .
• Under certain conditions (such as a sporty driving style , winter
conditions or unpaved roads) , the pressure monitor indicator may
be delayed.
• Ask your authorized Audi dealer if run-flat tires may be used on
your vehicle . Your vehicle registration becomes invalid if you u se
the se tires when not permitted. Damage to your vehicle or acci­
dents could also result.
