ONE-STAGE remote central locking, electric windows with driver's auto up/down, interior dome lights with timed delay/fade, a retractable luggage blind and a transponder-type engine immobiliser are all fitted standard to the Impreza RV. Once the key is inserted into the ignition lock and the ignition turned on, an antenna amplifier positioned around the ignition lock reads the transponder code and transmits it to the engine management and the immobiliser computer (ECU). The ECU then compares the transmitted code for the correct sequence and, if correct, allows the engine to start.
