cluster displayPractical hints Car care Index General notes on the central locking system
If the electronic key is inserted in the starter switch, the
vehicle cannot be locked or unlocked with the remote
control.
If the vehicle cannot be locked or unlocked:
•Aim transmitter eye at a receiver on either door
handle. Check the batteries of the electronic main
key, see page 363, or synchronize the remote
control, see page 365.
•Vehicles with KEYLESS-GO only:
A KEYLESS-GO-card must be recognized by the
system as being outside the vehicle to enable the
vehicle to be locked or unlocked (maximum distance
between card and doors or trunk is approx. 3 ft. (1
m). Check the location of the KEYLESS-GO-card, see
page 38. Check the batteries of the KEYLESS-GO-
card, see page 366. The trunk lid will open
automatically if a KEYLESS-GO card is detected in
the trunk, see page 38.Note:
If neither the remote control nor KEYLESS-GO system
functions, use the mechanical key to unlock or lock the
vehicle. To start engine, insert the electronic key in the
starter switch. There could be a slight delay until the
electronic key can be turned in the starter switch.

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 363 for checking batteries.

roof and switching on the driver’s seat ventilation 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 buttonŒ or‹, see page 45.
With vehicle centrally locked, the trunk can also be
opened by using the remote control.
