All pressure warning indicators in the display will be canceled.
Following each intentional change in specified pressures, tire pres­
sures must be saved again .
After the pressures are saved, the tire pressure monitoring system measures the current tire pressures and saves them as the new
specified pressures.
[ i ] Tip s
• The tire pressure is shown on the tire pressure label. The tire
pressure label is located either on the driver's side 8 -pillar or on the
inside of the fuel filler flap . The tire pressure label lists the recom­
mended 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, p lease see chapter=>
page 246.
• The tire pressure monitoring system helps the driver monitor t ire
pressures, but the driver is still responsible for mainta ining the
correct tire pressure. •

was not pressed.
• Audi Genuine Parts were not used for parts replacement.
• If snow chains are being used, system function can be compro­
mised due to the shielding properties of the chains.
• The tire pressure monitoring system may not be available
because of a radio ma lfunction.
• Transmitters with the same frequency, such as radio head­
phones in the veh icle or radio equipment, can cause a temporary
disruption of the system through excessive electromagnetic fields.
• Eliminate the interference if possible and then proceed as
follows: Turn off the engine for 20 minutes. Then drive another 10
min . If the warning light comes on again, you shou ld contact your
authorized Audi dealer immediately to have the problem corrected.
• Do not use commercially available tire sealants. Otherwise, the
e lectrical components of the tire pressure monitoring system will
no longer work properly and the sensor for the tire pressure moni ­
toring system will have to be replaced by an authorized Audi dealer
or other qualified workshop. •

& WARNING
Always store jacking equipment, spare wheel in the luggage
compartment. Tighten screw for the spare wheel securely. Under
no circumstances should you store the spare wheel or jack and
tools unsecured in the passenger compartment. This could cause
serious personal injury to passengers
in the vehicle in case of a
collision.
• The compact spare tire is for temporary use only and is so
marked on the sidewalls.
• Do not drive at speeds exceeding 50 mph (80 km/hi with the
compact spare wheel mounted. Also rapid acceleration, hard
braking and hard cornering must be avoided to help prevent loss
of vehicle control.
• Any continuous road use of the compact spare tire may result
in tire failure, loss of vehicle control and injury to vehicle occu­
pants.
• Do not put a snow chain on your compact spare tire. Due to the
smaller tire size, the chain will not fit properly and can thus
damage your vehicle. You could also lose the chain, as well as
control of the vehicle .
• If you have a flat front tire in road conditions which require
snow chains, first remove the undamaged rear wheel and mount
the compact spare wheel in its place. Then remove the damaged
front wheel, take the snow chains off it and attach them to the
wheel taken from the rear. This wheel can now be mounted on the
front with its snow chains. Check and adjust tire pressure promptly.
• Never use two or more compact spare tires at the same time.
0 Note
When using the compact spare wheel, note the following: •
After installing the compact spare wheel, the tire inflation pres­
sure should be checked and, if necessary, increased to 60 psi (4 .2
barl.
• The load carrying capacity is marked on the tire sidewal ls and
must not be exceeded .
• After installing the compact spare wheel, make sure that you
remount the flat tire in its storage area properly .
• The compact spare tire should be properly remounted in its
storage area as soon as the standard road tire can be replaced.
• Because the compact spare tire was specifically designed for
your vehicle, it must not be used on any other vehicle . Likewise,
compact spare wheels from other vehic les must not be used on your
vehicle.
• The compact spare tire must not be mounted on any other
wheels, nor must standard tires, snow tires, wheel covers or trim
rings be used with the compact spare wheel. If such use is
attempted, damage to these items or other vehicle components
may occur.
[ i] Tips
Check the inflation pressure of the compact spare tire (60 psi/4 .2
bar) periodically to keep the tire ready for use .•
Wheel change
Before changing a wheel
Observe the following precautions for your own and your
passenger's safety when changing a wheel.
- After you experience a tire failure, pull the car well away
from moving traffic and try to reach level ground before
you stop
~ & . ~

What do I do now? -__________________ __;__:....:....:..:: __ _
