Do not press the brake pedal while moving the balance wheel.
Through the driver display you can check the front and rear brake pressure and
the brake balance.
Notes:
To start the car, always proceed in this order: main switch, wait until display has booted (Audi Sport
logo disappears), then ignition switch.
The correct procedure to stop the car is the following:
1. Stop the engine using only the yellow switch (ignition switch/KL-15).
2. Wait at least 60 seconds.
3. Switch off the car using the red switch (main switch/KL-30).
If this procedure is followed correctly the OBD faults memory is saved and these faults can be
checked with the diagnostics tools at any time thereafter. These faults are saved until the memory
is deleted manually using the diagnostics program.
The diagnostic tool DiagRA-LE is recommended for customers to be able to check the cars.
Steering wheel module
The electronic steering wheel module permits activating different functions without removing hands from the
steering wheel.
Some of the buttons have double functionality.
