Radio frequency and infrared remote control
The electronic main key has an integrated radio
frequency and infrared remote control.
Due to the extended operational range of the remote
control, it could be possible to unintentionally lock or
unlock the vehicle by pressing the transmit button. If
one of the transmit buttons is pressed, the battery check
lamp lights up briefly – indicating that the batteries are
in order. See page 283 for checking batteries.
The vehicle doors, trunk and fuel filler flap can be
centrally locked and unlocked via remote control.
Opening and closing the windows and sliding/pop-up
roof remotely can only be done with the infrared portion
of the remote control. Aim transmitter eye at a
receiver (6 or 7), press and hold transmit button Œ
or ‹.
With vehicle centrally locked, the trunk can also be
opened by using the remote control.
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.1Transmit button
