Instruments and controls Operation Driving Instrument cluster display 42 Practical hints Car care Technical data Index Central locking system Simultaneous use of electronic key and KEYLESS-GO-card When using the electronic key and the KEYLESS-GOcard at the same time, the electronic key overrules the KEYLESS-GO-card. If the engine is started with the start-/stop button on the gear selector lever, and afterwards the electronic key is inserted in the starter switch, the engine continues to run with the gear selector lever in positions "R", "N", "D" plus ranges "4", "3", "2", "1" until it is stopped by using the start-/stop button on the gear selector lever. If the electronic key is inserted in the starter switch while the gear selector lever is in position "P", the electronic key takes over. The vehicle operates according to the electronic key position in the starter switch (see page 230), eventually even stopping the engine. Warning! When leaving the vehicle always remove the electronic key from the starter switch, take the KEYLESS-GO-card with you, and lock your vehicle. Unsupervised use of vehicle equipment may cause serious personal injury.
