Simultaneous use of electronic key and
KEYLESS-GO-card
When using the electronic key and the KEYLESS-GO-
card 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 222), eventually even stopping the
engine.
Wa r n i n g !
When leaving the vehicle always remove the
electronic key from the starter switch, take the
KEYLESS-GO-card with you, and lock your vehicle.
