SEAT Arona Stop Start Not Working

SEAT Arona Start Stop Not Working

The SEAT Arona start stop system helps save fuel and reduce CO2 emissions. Each time the ignition is switched on, the start stop system is automatically activated and if deactivation is required, it must be manually switched off each time the engine is started.


When automatic engine shutdown is activated, a green symbol is displayed SEAT Arona automatic shutdown activated and if the autostop function is unavailable, an amber symbol is displayed SEAT Arona start stop not available.

Messages may also be displayed along with the warning light. For example if the system is unable to automatically restart the engine after shutdown: ‘Start-Stop system deactivated. Start the engine manually’ and if there’s a fault with the system: ‘Start-Stop system: Fault! Function not available’.
