The brake system is bled with regular brake bleeding equipment from the workshop equipment program. Four brake calipers with
two bleeder connections each are used for the first time on an Audi model.
After the brake discs and/or brake pads of the service brakes are replaced, the function “Break in service brakes” must be activated
on the vehicle diagnostic tester. After successful activation, the function will be performed in the background (without the vehicle
diagnostic tester connected) during the next driving cycles. The function will be continued when a new driving cycle is started if
defined conditions are met. During the routine, recuperation procedures are temporarily deactivated and the vehicle is decelerated
using the service brakes. In the following driving cycles, a defined amount of braking energy is generated and used to bed in the
brake pads and brake disc friction rings. Once the necessary braking power has been generated, the function is deactivated auto-
matically and the vehicle once again prioritises deceleration via recuperation.
Final control diagnosis can be used to check the function of the hydraulic pump, the warning lamps, the brake lights and the sound
boxes (acoustic signal).
Wheels and tires, tire pressure monitoring
The Audi e-tron GT comes with 19" forged aluminum wheels as standard equipment. 19" to 21" wheels are available as optional
extras. The RS e‑tron GT has 20” cast aluminum wheels as standard equipment. 20” or 21” wheels are available as optional extras.
Both models have reduced rolling resistance summer tires as standard equipment (distance tires). These tires are also available for
the optional 19” and 20” wheels. Summer tires designed for sporty handling (performance tires) are also available as optional
equipment for the 21” wheels. All the wheels offered can be fitted with all-season tires if desired. Winter tires and snow chains can
be used on all 19” and 20” wheels.
Depending on the market, the vehicle has the TMS breakdown set or a temporary spare wheel. A jack is included if the vehicle is
equipped with a temporary spare wheel. The Tire Mobility System (TMS) and the temporary spare wheel may be offered as
optional equipment on a market-specific basis.
