Your AudiTT is equipped with an electro-mechanical parking brake. The parking brake replaces the conventional handbrake, and is mainly intended to prevent the AudiTT from rolling away accidentally.
However, the electro-mechanical parking brake also offers a number of convenience and safety features in addition to the functions of a normal handbrake.
When driving away
- The parking brake auto release function releases the parking brake automatically when you wish to start moving link►.
- When driving away on a gradient, the parking brake auto release function prevents the AudiTT from rolling back unintentionally. The braking force of the parking brake is only released when there is enough power at the wheels to make the AudiTT move in the desired direction.
Emergency braking function
An emergency braking function enables you to stop the AudiTT even if the conventional foot brake should fail to work link►.
Warning lamps
- The warning lamps
on the display and in the switch light up when the parking brake is applied with the ignition switched on.
- The warning lamps
on the display and in the switch light up for approximately 20 seconds when the parking brake is applied with the ignition switched off.
- The accelerator pedal must on no account be pressed inadvertently when a gear is engaged and the engine is running with the AudiTT stationary. The AudiTT could otherwise start moving immediately and possibly cause an accident.
- It is not possible to apply the parking brake if the electrical power supply fails. In this case, park the AudiTT on a level surface and select 1st gear (manual gearbox) or move the selector lever to position P (automatic gearbox) to prevent it from rolling. Obtain professional assistance.
Note
- The parking brake can be applied at any time - even when the ignition is switched off. However, the ignition must be switched on and the brake pedal pressed before the parking brake can be released.
- The parking brake is applied automatically if the driver s door is opened while the ignition is on. This is to prevent the AudiTT from accidentally rolling away.
- Any slight noise which may be heard when the parking brake is applied or released is quite normal and no cause for concern.
- The parking brake runs an automatic test cycle at regular intervals when the AudiTT is parked. This may cause a slight noise, which is normal.
- If the warning lamp
appears, there may be a parking brake malfunction link►.
- If the electrical power supply fails, it is not possible to release the parking brake (if it was applied) or to apply the parking brake (if it was released) ►. Obtain professional assistance.
