tion also is likely to impair the vehicle's handling and stopping
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.
W 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 328.
• 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 .
• 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.
• 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 .
Otherwise 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 pres ­
sure monitoring system to the load you are
carrying => page 328. •
Significant loss of air pressure ( )
The yellow symbol appears in the event of a significant
loss of air pressure.

If the warning light in the instrument cluster:::::, page 20
illuminates and then the ( symbol appears in the display
:::::, fig. 25 or:::::, fig. 26, this means the tire pressure is too 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:::::, page 351.

Tire pressure monitoring .
-Select Initialize wheels ~ page 43, fig. 27.
Programming is necessary:
• After the tires have been rotated on the vehicle (including use of
the spare tire*),
• If tires with new wheel sensors are used.
All pressure warning and system malfunction indicators in the
display will be canceled.
If a wheel change has been made, it is necessary to complete the
Initialize wheels function.
Th e tire pressure monitoring system is not available dur ing the
programming process and no pressure and temperature values are
displayed on the MMI display.
After you have selected the funct ion, the new wheels are
programmed and the actual pressures are stored. This learning
phase can take up to 20 minutes driving time.•

=> fig. 29 symbol appears in the display, the
tire pressure monitoring system is not available. This can have
various causes.
• If the message appears at the end of the learning process, the
system cannot recognize the wheels installed on the vehicle. This
can be because one or more wheels without a wheel sensor were
insta lled .
• A wheel sensor or other component may have failed.
• The system has detected more than 5 wheels with wheel sensors
in the vehicle, for example when carrying snow tires.
• A tire was changed but the
Initialize wheels function was not
activated
=> page 45.
• Audi replacement parts were not used.
• 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 malfunction.

Audi lane assist -_____________________ __.
Audi lane assist
Lane assist
Applies to vehicles: with lane assist
Description
Lane assist helps you keep your vehicle in your lane.
Lane assist uses a camera to detect lane boundary lines. If the
system detects that your vehicle is about to leave a lane boundary
line, the steering wheel
vibrates to alert the driver. If lane assist
detects boundary lines on both sides of the vehicle's lane, the
system enters active standby mode, which is indicated by the green
indicator light/: on the instrument cluster.
If the system is in active standby mode and the turn signal is acti­
vated before driving over the boundary line, the warning does not
occur since the system allows for intentional lane changes.
The system is designed for driving on freeways and expanded high­
ways and thus works only at speeds of 40 mph (65 km/h) or more.
& WARNING
• Lane assist will not keep your vehicle in your lane. The system
only warns the driver when the vehicle is leaving the lane. The
driver is always responsible for keeping the vehicle in the lane.
• The camera is not able to detect all lane boundary lines and in
some cases might also detect lane structures or objects as
boundary lines. This can lead to incorrect warnings or warnings
that fail to go off at all.
• The camera's visibility can be impaired by vehicles ahead of
you, for instance, or by rain, snow, heavy spray or light shining into
the camera lens. This can cause lane assist to fail to detect
boundary lines. •
