Applies to Audi A3s: with auxiliary heating/ventilation
Plug-in hybrid drive*: Please note the information on ►Link.
The auxiliary heating/ventilation system heats and ventilates the interior of the Audi A3 and can be used either when the engine is off or when driving (for instance while the engine is warming up).
There are two ways to control the system:
Switching on/off manually - You can switch the auxiliary heating/ventilation on and off immediately either:
Either the auxiliary heating or the auxiliary ventilation will be switched on, depending on the ambient temperature and the temperature you have selected.
Switching on/off automatically (setting the timer) - You can use the timer to specify the time of day at which the temperature inside the Audi A3 is to reach the desired level. Your temperature setting and the ambient temperature will then determine when the auxiliary heating or auxiliary ventilation is switched on. You can set three different timers ►Link using the MMI* or one timer using the remote control ►Link.
Driver messages on the display
Auxiliary heating/ventilation: currently unavailable. Battery voltage too low.If this message appears, the battery is not sufficiently charged. In this case, the engine must be switched on in order to use the auxiliary heating.
Auxiliary heating/ventilation: currently unavailable. Not enough fuel.To conserve fuel, the auxiliary heating cannot be switched on if the fuel level is low.
Auxiliary heating/ventilation: system fault! Currently unavailableIf this message appears, a system malfunction has occurred. Drive to a qualified workshop soon and have the fault rectified.
WARNING!
- The auxiliary heating must not be allowed to run when the Audi A3 is in a confined space because it can give off toxic fumes.
- To avoid any possible fire risk, never have the auxiliary heating switched on when refuelling the Audi A3.
- Because of the high temperatures which occur when the auxiliary heating is running, make sure when parking the car that the exhaust outlet under the car is not obstructed in any way and that the exhaust gases do not come into contact with flammable materials (fire risk).
Note
- The auxiliary heating/ventilation system heats/cools the interior to the temperature you last selected on the air conditioner ►Link.
- At low outside temperatures some visible water vapour may form in the engine compartment. This is a normal phenomenon, and no reason for concern.
- The auxiliary heating/ventilation will not switch on or will switch itself off earlier than intended if the battery charge or fuel level is low.
