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 323 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
than the size indicated on the vehicle placard or tire inflation pressure
label, you should determine the proper tire inflation pressure for
those tires.)
As an added safety feature, your vehicle has been equipped with a tire
pressure monitoring system (TPMS) that illuminates a low tire pres ­
sure telltale when one or more of your tires is significantly under­
inflated . Accordingly, when the low tire pressure telltale illuminates,
you should stop and check your tires as soon as possible, and inflate
them to the proper pressure. Driving on a significantly under-inflated
tire causes the tire to overheat and can lead to tire failure . Under­
inflation also 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 mainte­
nance, and it is the driver's responsibility to maintain correct tire
pressure, even if under-inflation has not reached the level to trigger
illumination of the TPMS low tire pressure telltale.
Your vehicle has also been equipped with a TPMS malfunction indi­
cator to indicate when the system is not operating properly. The
TPMS malfunction indicator is combined with the low tire pressure
telltale. When the system detects a malfunction, the telltale will
flash for approximately one minute and then remain continuously illuminated. This sequence will continue upon subsequent vehicle
start-ups as long as the malfunction exists .
When the malfunction indicator is illuminated, the system may not
be able to detect or signal low tire pressure as intended. TPMS
malfunctions may occur for a variety of reasons, including the instal-..,_

lation of replacement or alternate tires or wheels on the vehicle that
prevent the TPMS from functioning properly. Always check the TPMS
malfunction telltale after replacing one or more tires or wheels on
your vehicle to ensure that the replacement or alternate tires and
wheels allow the TPMS to continue to function properly .•
App lies to veh icles: with Tire pressure monitoring syste m
Introduction
The tire pressure monitoring system monitors air pres­
sure in all four road wheels and the spare tire* while the
vehicle is moving.
As soon as the tire pressure monitoring system senses a significant
loss of air pressure in one or several tires, text messages and yellow
symbols appear in the instrument cluster display to alert the driver.
The
1warning light in the instrument cluster comes on when the tire
is significantly underinflated
=> page 17.
The warning light
L also illuminates in the case of a system malfunc­
tion.
The system continuously receives radio signals from sensors located
inside each tire.
Be aware that tire pressure is also dependent on the temperature of
the tire. For every 18 °F (10 °C) increase in tire temperature, tire pres­
sure increases by about 1.5 psi (0.1 bar). The tire warms up while the
vehicle is moving and tire pressure rises. So you should adjust tire
pressure only when the tires are
cold, when the temperature of the
tires is roughly the same as the ambient air temperature.
In order to keep the tire pressure monitoring system properly cali­
brated, tire pressure on all four tires and on the spare tire* should be
checked at regular intervals, adjusted if necessary and saved in the
proper setting (recommended pressure)=>
page 330.
The tire pressure is shown on the tire pressure label. On USA vehicles,
the tire pressure label is located on the driver's side B-pillar. On
Canada vehicles, the tire pressure label is located either on the
Safety first
driver's side B-pillar or inside the fuel filler flap. The tire pressure
label lists the recommended cold tire inflation pressures for the
vehicle at its maximum capacity weight and the tires that were on
your vehicle at the time it was manufactured. For recommended tire
pressures for normal load conditions, please see chapter
=> page 310.
The current temperatures and pressure of your tires can be viewed in
the MMI
=> page 329.
& WARNING
• When the tire pressure monitoring system warning light is lit,
one or more of your tires is significantly under-inflated. You
should stop and check your tires as soon as possible, and inflate
them to the proper pressure as indicated on the vehicle's tire pres­ sure label =>
page 310. 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 stop­
ping ability.
• Do not adjust tire pressure when tire temperature is excessive.
This could lead to serious tire damage and even cause the tire to
burst, with the additional danger of an accident.
<£> For the sake of the environment
Driving with under-inflated tires reduces fuel efficiency and tire tread
life.
(I) Tips
• Each tire, including the spare*, should be checked monthly when
cold and set to the recommended inflation pressure as specified on
the tire pressure label=>
page 310.
• The tire pressure monitoring system helps the driver to keep an
eye on tire pressures. But the driver still has the responsibility for
maintaining the correct tire pressure. .,,,
