Radio frequency and infrared remote control
The electronic key has an integrated radio frequency

lamp lights up briefly – indicating that the batteries are
in order. See page 284 for checking batteries.

of the remote control. Aim transmitter eye at a
receiver (6 or 7), press and hold transmit button Œ
or ‹.
If the electronic key is inserted in steering lock, the
vehicle cannot be locked or unlocked, and the trunk lid
cannot be opened with the remote control.
