• Tire pressure must only be adjusted when the temperature of the
tires is about the same as ambient air temperature .
• When tires are replaced, the sensors and valves should not be
detached or exchanged . Only the valve core needs to be replaced and,
if necessary, the valve and the wheel electronics replaced .
• The tire pressure monitoring system on your Audi was calibrated
usiing tires with the "AO" or "RO" identification. We recommend
using these tires.
• If you should put different wheels and tires on your vehicle (e.g.
winter wheels and tires), you must be certain that the wheels and
tires are compatible with the tire pressure monitoring system. Other­
wise the system will register a malfunction and a fault message will be displayed. For more information, contact your authorized Audi
dealer.
• Adjust the tire pressure and store the pressure in the tire pressure
monitoring system to the load you are carrying=:>

low in one or several tires (including spare tire* with sensor).
- Stop driving as soon as possible without endangering
yourself or other drivers on the road.
- Inspect the tire or tires.
- Change the tire if necessary=>

Storing tire pressures
Correct storage of specified pressure is the basic require­
ment for reliable tire pressure monitoring.
In order for the tire pressure monitoring system to operate
appropriately, you have to re-save the specified pressures
whenever you adjust tire pressure, for example when the load
condition of your vehicle changes . Proceed as follows:
Corr ecting tir e pr essure
- Check the pressure in the tires (including the spare t ire*) .
- Adjust air pressure as needed in accordance with t he infor -
mation on the label located e ither on the driver's side B ­
pillar (visible when the door is open), inside the fuel filler
flap and additionally in the manual.
Saving tire p ressures
- Turn on the ignition.
- Press the [
CAR] function button .
- Select
Systems in the CAR menu .
- Select
Tire pressure mon itoring .
-Select Sto re curr. tire pressure s~ page 329, fig . 259 .
All pressure warning indicators in the display will be canceled.
Following each intentional change in specified pressures, tire pres­
sures must be resaved . After the
pressures are saved, the tire pressure monitoring system
measures the c urrent tire pressures and saves them as the new spec­
ified pressures .
(I] Tips
• The tire pressure is shown on the tire pressure label. On USA vehi­
cles, the tire pressure label is located on the driver's side B-pillar. On
Canada veh icles, the tire pressure label is located either on the
driver's side B-pillar or inside the fuel filler flap . The tire pressure
label lists the recommended cold t ire 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 tire pressure monitoring system helps the driver to keep an
eye on tire p ressures. But the driver still has the responsib ility for
maintaining the correct tire pressure .
• If your veh icle is eq uipped w ith a standard spare ti re*, it must be
inflated to the maximum pressure specified for the vehicle .•
