1 Tires are supplied and warranted by their manufacturer. High-performance tires are designed for optimum performance and handling in warm
climates. 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 winter or all-season
tire specified for your car or its equivalent. These high-performance tires also have a lower aspect ratio that aids performance and handling;
however, in order to avoid tire, rim or vehicle damage, it is important that the inflation pressure is regularly checked and maintained at optimum
levels. Please also remember in making your selection that, while these tires deliver responsive handling, they may ride less comfortably and
make more noise than other choices. Finally, these tires may wear more quickly than other choices.

Electrical system
Audi drive select
The 2015 A3 is equipped with Audi drive select. At model
introduction, the engine/transmission, power steering and
Adaptive cruise control can be tailored to the driver through
the Audi drive select feature. The driver can choose
between three operating modes: comfort, auto and
dynamic. In addition, the vehicle set-up can be customer
configured using individual mode. More vehicle systems
will be added to the Audi drive select at a later date.

Depending on the infotainment system installed, Audi drive
select can be configured either using the button in the
instrument panel or via the Car menu in the MMI.
The selected mode of the system is indicated in the MMI
display. Individual mode is only available with infotainment
versions MMI Navigation and MMI Navigation with Audi
connect.

Functional features:

to the vehicle key in use.
The mode can be changed when the vehicle is stationary
or while driving (requirement: terminal 15 "on").
To activate a selected mode for the Transmission/engine,
the accelerator pedal must briefly return to the idle
position.
